"Exposure: Radiation Victims Speak Out" Web Series Reveals Personal Struggles, Triumphs

Over 20 years ago, the Hiroshima newspaper Chugoku Shimbun sent a team of reporters to 15 nations around the world to gather personal accounts of people affected by radiation - from reactor accidents, accidental contamination, to nuclear weapons manufacturing and testing. The interviews were initially published as a series of eight newspaper features titled "Sekai no Hibakusha," or "Hibakusha (figuratively, "atomic bomb survivors") Around the World." This monumental series won a Japan Newspaper Publishers and Editors Association award in 1990, and was subsequently published in book form the following year. Executive Director of the Chugoku Shimbun Yukio Ogata explains,

"Largely as a result of the articles' success in bringing the public's attention to the dangers of radiation, a number of victims of radioactive contamination from areas as far-flung as Chernobyl and Bikini Atoll were able to participate in the world convention held in Hiroshima by the International Physicians for the Prevention of Nuclear War in October 1989...[T]he convention heard details concerning the damage caused by nuclear testing in Kazakhstan, which until then had been shrouded in secrecy. In turn, this disclosure of widespread destruction of the environment prompted the Chugoku Shimbun to instigate the first-ever investigation of the testing area.

At the same time, the articles served to emphasize the role that Japan could play to help radiation victims around the world. The fact that the articles have prompted the exchange of information concerning the treatment of radiation victims in Japan to help those in a similar plight in other countries is a great source of satisfaction to us at the Chugoku Shimbun. We hope that, in the future, Japan will become known as an information center for radiation victims and the treatment of their illnesses."

In March 2013, the Hiroshima Peace Media Center re-released the entire series of 134 interviews free online as "EXPOSURE: Victims of Radiation Speak Out". From the English-language introduction by Dr. Robert Jay Lifton, Director of the Center on Violence and Human Survival at the CUNY John Jay College of Criminal Justice notes,

"There is compelling appropriateness in the project's being undertaken by concerned journalists from Hiroshima. From the time the bomb was dropped, the Chugoku Shimbun, as Hiroshima's leading newspaper, has been a prime source of information about the experiences and feelings of the people of that city over subsequent decades. Its editors and writers have taken on what I call a 'survivor mission' on behalf of the city's victims, a commitment to transforming the fear, conflict, and pain of the survivors into an active exploratory enterprise of profound significance.

Their contribution goes even beyond their descriptions of the human effects of radiation. In the way they have approached their study, they have demonstrated what I call a species mentality, a commitment that transcends immediate group or nationality and extends to all of humankind. They evoke in us a sense of shared fate, of universal susceptibility to a technology that knows no boundaries, geographical or temporal. We are all in this together, as potential victims and potential perpetrators as well.

Among the regions and incidents covered in these interviews are Chernobyl, the 1987 Goiânia Accident in Brazil, contamination from the Cold War weapons program at Semipalatinsk, Kazakhstan, and the Hanford Nuclear Reservation site in Washington State.

Self-Powered Sensors Enable Monitoring Reactor Fuel Rod Status During Total Power Failures

Researchers at Penn State and Idaho National Laboratory have announced an important breakthrough in sensor technology that promises to improve operating safety and control of reactors in the event of total power failure:

Penn State researchers [have] teamed with the Idaho National Laboratory to create a self-powered sensor capable of harnessing heat from nuclear reactors' harsh operating environments to transmit data without electronic networks. The team [are presenting] their research at the Acoustical Society of America's...164th Meeting, October 22-26, 2012, in Kansas City, Missouri.

"Thermoacoustics exploits the interaction between heat and sound waves," explains Randall A. Ali, a graduate student studying acoustics at Penn State. "Thermoacoustic sensors can operate without moving parts and don't require external power if a heat source, such as fuel in a nuclear reactor, is available."

In the unlikely (but not unprecedented) event of complete power failure, as occurred when backup generators at Fukushima were flooded with seawater following the earthquake and tsunami of 11 March 2011, these self-powered sensors would allow plant operators to continue monitoring conditions within the reactor in the critical first minutes and hours of an emergency.

• Quantumday has a excellent explainer post on thermoacoustic devices.
• A September 22, 2011 memo from Pacific Northwest National Laboratory to Idaho National Laboratory discussing centralized online monitoring and information integration systems addressed the need for such devices.

'Meltdowns' Making Safer Reactors: CEA's PLINIUS Platform and Finland's VTT

[See also "Alexander Borovoi: Chernobyl Explorer"]

The mention of the word meltdown conjures our deepest fears about nuclear power: an out-of-control reactor core collapsing into molten radioactive "lava" that consumes metal, reactor housings, concrete foundations - even, as cautionary tales warn, the ground beneath the reactor itself. While the "China Syndrome" is thankfully just a frightening fiction, complete or partial meltdowns have occurred in several severe accidents, notably Three Mile Island, Chernobyl, and most recently at three of Fukushima Daiichi's reactors. Recent European studies have even suggested that the likelihood of a severe accident is much higher than previously thought:

"Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred, scientists at the Max Planck Institute for Chemistry in Mainz and the Cyprus Institute have calculated that such events may occur once every 10 to 20 years (based on the current number of reactors) - some 200 times more often than estimated in the past."

Clearly, one important goal must be designing reactors that resist losing structural integrity in the event of an accident or meltdown, that can reliably withstand molten corium's extreme temperatures without breaching containment. Our scientific understanding has been limited in the past by the difficulty of studying meltdowns during actual emergencies, and in recreating their volcanic conditions in a controlled environment. This is one of the reasons why the innovative prototypic core melt research being performed at facilities like CEA's PLINIUS Platform, and the VTT Technical Research Centre of Finland, is crucial in developing new building materials for safer nuclear plants, as well as learning to prevent meltdowns and minimizing environmental exposure should one occur.

PLINIUS is an experimental platform for the study of severe accidents using prototypic corium, laboratory-created high-temperature molten mixtures containing depleted uranium oxides that recreate the "melt" of theoretical "meltdowns".

Its four facilities study different aspects of corium formation and behavior: VULCANO is a "50-100 kg corium melting facility," where oxides and metals are combined in a rotating cylindrical furnace and melted using induction heating, transferred plasma arc technology, or through exothermic redox reactions ("uranium thermite"). The "melt" is then poured into a test section of concrete, ceramic, or other material to study flow patterns, chemistry, and resulting material structure. COLIMA is a smaller, enclosed induction-heated unit that allows study of corium/gas interaction and aerosol formation, while KROTOS is used to observe and measure the behavior of small (~5kg) quantities of corium when dropped into water. As PLINIUS' site understatedly describes, "energetic steam explosions can be triggered and studied":

Heat transfer between the hot molten core with the colder volatile water [in KROTOS] is so intense and rapid that the timescale for heat transfer is shorter than the timescale for pressure relief, leading to the formation of a shock wave. This shock wave is intensified as a result of further mixing and energy transfer as it travels through the mixture.

The smallest of PLINIUS' facilities, VITI, (image above is a tiny molten corium droplet in the VITI crucible) specializes in tests using corium samples of less than 100 grams, mainly used for thermophysical/thermochemical property analysis, or controlled-atmosphere material interaction tests.

While Finland's Technical Research Center (VTT) conducts international applied industrial research and analysis in a variety of fields, its nuclear reactor safety program has also developed advanced simulated reactor environmental modeling (APROS) and reactor aging studies, as well as joint corium melt research with CEA's PLINIUS. Ongoing research into the science behind meltdowns, such as the work being done at PLINIUS and VTT, will help create safer, more accident-proof nuclear reactors and containment structures for our world's endlessly growing need for cleaner energy.

Jellyfish-Like Creatures Cause Shutdown of Diablo Canyon Nuclear Plant

An influx of "thumb-sized" creatures in cooling sea water proved too much for a California nuclear power plant this week, according to NDTV:

The Diablo Canyon nuclear power plant, in San Luis, California, shut down its Unit 2 reactor after sea salp, a planktonic jellyfish-like creature clogged the screens of the plant’s coolant water intake. The influx of the gelatinous animals was discovered Wednesday. Initially, plant operators reduced its functional reactor to 25% capacity. Unit 1 had a scheduled refueling earlier in the week, and had been shut down.

In smaller quantities away from industrial activity, Salps have been known to have a beneficial effect on seawater by consuming bacteria. The San Luis coastal salp invasion may be just a periodic bloom.

Cerenkov Radiation

A RadioActive! reader sent us this fascinating image of blue Cerenkov radiation from Ohio State University's research reactor:

"...attached is a photo...of our research reactor at OSU, which I took from the pool-top during operation at about 50 kW (thermal). The blue Cerenkov glow caused by photoelectrons, Compton electrons, and beta particles is evident here, but [in my opinion] is much prettier at our licensed power of 500 kW!

Name That Ohio (Nuclear) Plant!

I'd like to call on the expertise of RadioActive! readers to help me identify this power plant. This photo was taken Tuesday 4/4/06 from interstate highway 80-90 in northern Ohio roughly near Toledo, where the highway parallels state route 2. I think it is a nuclear reactor (judging from the containment structure), but it does not resemble either of Ohio's two reactors on the NRC list, the Davis-Besse or Perry power plants. Any suggestions and clues would be appreciated.

By the way, check out the Google Maps satellite image of Perry, Ohio. On my computer, the grid area directly corresponding to the Perry nuclear facility is blurred/smeared. Is this an intentional censoring of the image for security reasons, I wonder?

UPDATE: The Google Maps image of The Davis-Besse facility, however, is not blurred.

St. Petersburg: Report Says Renovation of Chernobyl-Type Reactor Rushed

From the St. Petersburg Times, disturbing news about an aging RBMK-1000 type reactor being renovated for reactivation:

Report Says Renovation of Chernobyl-Type Reactor Rushed
October 8, 2004
By Vladimir Kovalev
STAFF WRITER
A series of mishaps has occurred during the renovation of reactor No.1 at the Leningrad Nuclear Power Plant, or LAES, in Sosnovy Bor outside St. Petersburg because basic safety regulations were ignored, according to a new report.

Reactor No. 1 is the oldest of four reactors at the plant and its official working life has expired, but the Federal Nuclear Power Agency is seeking to extend it. It is an RBMK-1000 reactor, the same type that caused the Chernobyl disaster in 1986, and LAES management plan to restart it this fall.

Sergei Kharitonov, a former employee of the plant and now an environmental campaigner, wrote in the report that the safety systems for the reactors were installed in a rush, in some cases by unqualified workers, breaching standards on how the work should be done, the report said.

As a result, two workers died in the spring, including a 32-year-old construction worker who fell from the wall of bloc No.1 in April and a 42-year-old fitter was crushed while working on bloc No.2 in May.

"[The management] paid most of its attention to [staff] training for the launch of bloc No.1," Kharitonov quoted LAES management as saying in a statement on July 16. "The lectures were poorly attended ... Two lectures remain to be conducted. Such a situation is unacceptable, when the bloc [No.1] is about to launched, but employees are not ready for it."

More Nuclear Troubles in the Ukraine

Australia's Herald Sun reports of serious problems last week at the new Khmelnitsky nuclear power plant at Neteshin:

The reactor at Khmelnitsky power station had to be shut down on Sunday, less than two hours after it went into operation, Interfax news agency reported on yesterday. Further technical failures prevented it operating on Monday and Tuesday.

"These incidents do not represent any threat to the public or to the environment," state nuclear energy company Energoatom said in a statement.

Ukraine was the scene of the world's worst civilian nuclear disaster in 1986, when a reactor at Chernobyl nuclear power station exploded, contaminating large areas in Ukraine and neighbouring Belarus and Russia. Energoatom confirmed incidents had occurred at Khmelnitsky but said it "saw no cause for concern".

"Certain media inflated the affair," it said.

The K2 Russian-designed VVER pressurised water reactor at Khmelnitsky, which has a capacity of 1000 megawatts, was brought on stream on Sunday at a ceremony attended by Ukrainian President Leonid Kuchma. But it ground to a halt almost immediately.

An official at Ukraine's governmental commission for atomic energy said that automatic security systems at the power plant had cut off the reactor from the electricity grid. The reactor was reconnected to the grid three hours later but had to be totally shut down later because of a failure in the cooling system caused by a power breakdown, the official added.

The reactor was restarted on Monday, only to be stopped again yesterday, officially to test its shut-down system and cooling units.

Not an auspicious beginning, I'm afraid, despite ITAR-TASS' rather glowing (if spoken-too-soon) praise. I truly hope plant officials don't do something silly...like deciding to bypass safety measures to "get the thing started" - we know where that can lead.

Frighteningly, for many regions of the world like Ukraine, nuclear energy is currently one of the most viable energy options. Having a cold climate with existing high pollution, more use of fuels like coal would cause further damage to air quality and likely increase rainfall pH levels. Additionally, research into developing workable technologies such as geothermal, solar and wind power requires large-scale financial investment that strapped nations like the Ukraine simply can't afford.

From "Non-traditional sources of energy may be key to Ukraine's future," by Roman Woronowycz of Kyiv [Kiev] Press Bureau, in the Ukraine Weekly, April 30, 2000:

Once looked at with keen interest, a Ukrainian government choked by money shortages has cast aside any serious work on the development of non-traditional renewable energy sources, such as wind and solar power, as an alternative to its primary reliance on atomic energy.

Ukraine has made much of the West's delays in providing financing to complete two traditional and controversial new reactors that Kyiv wants completed to offset the power that will be lost when Chornobyl shuts down at the end of this year. However, there are those here and in ecologically minded countries such as Germany who believe that Ukraine has no recourse but to reconsider non-traditional energy sources as well, which could do the work of the nuclear power plants as efficiently and with none of the risk.

One such person is the institute's director, Viktor Shulha, a gray-haired, 60-something scientist with a strong belief that Ukraine must turn to wind and solar power to meet its energy demands. Mr. Shulha said he has been frustrated in his attempts to turn the government's ear to his cause by the most familiar of laments in Ukraine: there simply is no money for it.

Mr. Shulha became the director of the Institute of Energy Engineering when it was formed 10 years ago by the Ministry of Energy, and at one time had an extensive group of advisors and experts. The team already had developed recommendations and a plan for developing wind energy when it came up against the insurmountable wall of Ukraine's current economic reality.

"We decided that for Ukraine the best potential would be to develop wind and biomass sources, and the government put the accent on wind energy. But, as it turned out, Ukraine had no finances and the experts moved on," said Mr. Shulha.

More than any other nation, the Ukraine should understand the risks of nuclear power and the awesome consequences of "inconsequential" mistakes - but with another bitter winter on the way, time manages to dull the sting of fear almost as smoothly as reassuring official words. "If someone you know was killed in a car crash nearly twenty years ago, would you stop riding in cars for the rest of your life?"

Atomic technology has advanced since the 1986 disaster as wealthier nuclear-dependent nations, like France, Belgium and Italy, have invested considerable sums in developing safer meltdown-resistant reactor designs. Nonetheless, as history has shown, nothing is truly 100% foolproof - and make no mistake, EnergoAtom is a beleaguered interest, by any account [check out news stories linked below]. Let's keep our fingers crossed, and our orbiting Eyes In The Sky watchful.

Missing Yankee Nuclear Fuel Rods Found

From the Champlain Channel WPTZ-TV
Fuel Rods Found In Pool At Plant

POSTED: 8:21 pm EDT July 13, 2004
UPDATED: 9:24 am EDT July 14, 2004

VERNON, Vt. -- Two highly radioactive pieces of spent nuclear fuel reported missing three months ago appear to have been where they were supposed to be all along.

A spokesman for the federal Nuclear Regulatory Commission said Vermont Yankee has told the NRC it found the fuel rods in the spent fuel pool at the plant. Vermont Yankee officials said last week they had found records at a General Electric laboratory in California that appeared to provide a key clue as to the fuel pieces' whereabouts.

Workers found the spent rods inside a cylinder that was sent to Vermont Yankee by GE specifically to hold the fuel segments. Searchers found the canister at the bottom of the spent rod pool and opened it up, discovering the rods late Tuesday afternoon. Vermont Yankee said it has updated its records to make sure something like that doesn't happen again.

Yankee Nuclear Powers Up Once More...Er, Hold That Thought

BURLINGTON, Vt. -- There was another scare Thursday morning at Vermont Yankee. This, after the nuclear power plant had just resumed full power Wednesday night following a fire that forced a 19-day shutdown.

Officials said an excess of oil caused black smoke to blow out of a furnace inside a building on the grounds Thursday morning. An onsite fire brigade shut off the furnace switch a little after 4 a.m. A representative for the plant's parent company said there was no damage or injuries from the incident.

I don't know about you, but I'd feel a little leery of uprating an old plant with repeated "problems" like this...and they still haven't found the missing two pieces of fuel rod.

Vermont Yankee Plant to Remain Offline Indefinitely

Following a recent transformer fire at the Vermont Yankee nuclear power plant, officials have decided to keep the facility offline for more thorough investigation.

From the Champlain Channel:

UPDATED: 10:40 am EDT June 24, 2004

BURLINGTON, Vt. -- Vermont Yankee remained off-line Thursday after two fires there on Friday, but Entergy now says the plant's safety system didn't respond the way it should have.

Vermont Yankee officials said the accident was far less serious than originally feared, but critics charge it's the pattern they're concerned about. It's just one safety lapse after the next, they said. "A fire at a nuclear plant is a big deal," one customer said. Five days after the fire there, critics call the accident more serious -- and more telling -- than first believed.

"Powerplants have what's called a bathtub curve," said longtime nuclear engineer Arnie Gundersen. "They fail a lot when they're new. They fail a lot when they're old. In between though, they don't fail a lot. I have been saying that they're on the upslope of the bathtub curve, and we should see more of these failures as the plant gets older." Gundersen cites three forced shutdowns in nine months due to broken valves and pumps.

Vermont Yankee turns 32 this year, but marks the year with a series of embarrassments: cracks in the steam dryer, a pair of missing fuel rods and, most recently, the transformer fire. Public service commissioner David O'Brien sent the state nuclear engineer to Vernon this week for a closer look. "We've got to find out what caused it," Public Service Commissioner David O'Brien said. "Was it a problem with the equipment? Was it a problem with maintenance? We've got to find that out first."

Officials hope to find out what caused the accident within a week. The plant will remain off-line indefinitely. The NRC, meanwhile, still plans to assess Vermont Yankee for its proposed uprate later this summer.

Got MOX?

Shikoku Electric Co.'s Ikata No. 3 reactor is likely to become the third facility in Japan to go "pluthermal" - to use MOX, or mixed-oxide, fuel for power generation. From the Asahi Shimbun:

Shikoku Electric Power Company...Monday informed the Ehime prefectural government of its plans to burn MOX nuclear fuel there by fiscal 2010.

Pluthermal power is controversial because it uses plutonium-uranium mixed oxide fuel, or MOX. Under this method, plutonium extracted from spent nuclear fuel is burned in reactors originally designed for uranium fuel. Pluthermal power is key to the nation's nuclear-fuel recycling program.

Critics warn the pluthermal method carries more health and safety risks to reactors originally designed to burn only uranium fuel. Shikoku Electric Power's plan follows those of Kansai Electric Power Co. and Kyushu Electric Power Co. Kansai Electric Power got the green light from the Fukui prefectural governor in March for its plan to burn MOX at its Takahama nuclear power plant. Kyushu Electric Power in late April notified the Saga prefectural government and the town of Genkai that it plans to burn MOX as early as 2009 at one of its reactors there.

Under Shikoku Electric Power's plan, no more than 16 of the 157 uranium-fuel elements in what are called fuel bundles-groups of fuel elements burned in a reactor-will initially be replaced with MOX at the No. 3 reactor in Ikata. The number of MOX elements will eventually be increased to about one-fourth of the bundle, with the maximum set at 40.

Greenaction-Japan is a organization which opposes the use of "pluthermal" (a Japanese term combining the words "plutonium" and "thermal") power, citing increased safety concerns:

Over the last several years the government and electric utilities have argued that the pluthermal program is a method of recycling precious resources. They claim that it is in Japan's best interest to extract the uranium and plutonium contained in spent nuclear fuel rather than directly disposing of it as some countries do. The argument used is that Japan is an energy poor country which needs to conserve uranium resources and use plutonium for energy security purposes.

Recently promoters of the pluthermal program have begun to argue that the program is also necessary in order to reduce the amount of surplus plutonium accumulated as a result of overseas reprocessing. Since mid- 2001, the Japanese government and electric utilities have put forward yet another argument for the pluthermal program. They claim that without the pluthermal program Japanese nuclear power plants would be unable to continue to produce power...The use of MOX fuel increases the risk and severity of a nuclear accident. When using MOX fuel, the control rods' capacity to function is reduced and power output is less stable and harder to control.

The NRC has a quarterly publication called the MOX: Mixed Oxide Fuels Newsletter, "published quarterly to highlight recent news and events associated with the NRC's licensing of a mixed oxide fuel fabrication facility." The lastest March 2004 issue [PDF file] among other things, talks about the

...October 2003...DOE fil[ing of] an application for license to export up to 140 kilograms of plutonium dioxide to the Cadarache and MELOX MOX fuel fabrication facilities in France. The plutonium would be used to fabricate four MOX fuellead test assemblies, which would be returned to the U.S. for proposed MOX fuel qualification tests in the Catawba Nuclear Power Station. [a two-unit power plant located on Lake Wylie in York County, S.C.]

MOX is (pardon the pun) a highly-charged topic in the United States as well, as the anti-mixed-oxide site Nix-MOX clearly demonstrates with its "Top 10 Reasons to Oppose the Use of MOX":

"MOX IS A BAD IDEA!! MOX infrastructure supplies all the pieces needed for making plutonium a desirable commodity, while it claims to dispose of it. MOX legitimizes the production of plutonium by foreign countries, and creates a market for something that could used in a weapon of mass destruction. Plutonium is dangerous and should be kept out of our economy and out of our commercial reactors."

Illinois: "Nuclear America"?

With half the state's electricity generated at nuclear power plants, Illinois qualifies as "highly dependent" on this form of energy; and with 11 currently operating commercial reactors, it's tied in first place with Pennsylvania for the "Most Nuclear Plants." Not on the list? The now-decommissioned Zion 1 and 2 Nuclear Plant near Gurnee, IL, or the decommissioned Dresden 1 plant in Morris. from the NRC's Decommissioned Plants Section:

Zion Units 1 and 2 were permanently shut down on February 13, 1998. The fuel was transferred to the spent fuel pool, and the owner submitted the certification of fuel transfer on March 9, 1998. A public meeting was held on June 1, 1998, to inform the public of the shutdown plans. The owner has converted the turbine-generators into synchronous condensers and have isolated the spent fuel pool within a fuel building "nuclear island." The plant has been placed in SAFSTOR, where it will remain until about 2013 when the decommissioning trust fund will be sufficient to conduct DECON activities. The owner will retain the spent fuel until it is accepted by the Department of Energy. The owner submitted the post-shutdown decommissioning activities report (PSDAR), site-specific cost estimate, and fuel management plan on February 14, 2000. A public meeting to discuss the PSDAR was held on April 26, 2000.

Zion may be out of service, but the Village of Gurnee maintains a webpage detailing the emergency evacuation procedure in event of an accident at the plant.

Vermonters Protest Proposed 20% Yankee Nuclear "Uprating"

The embattled, aging Vermont Yankee nuclear power plant in Vernon (which recently made headlines when two highly radioactive pieces of fuel rod were reported missing) is expected to be given a 20% power boost - or "uprating."

This doesn't sit very well with many residents of this characteristically "back-to-nature" region. From today's Brattleboro [VT] Reformer:

BRATTLEBORO -- Flashing placards, more than 125 nuclear power protesters marched downtown on Saturday, calling for a cease to "uprate" proceedings and, moreover, for Vermont Yankee's closing. The group, which made its way from the Brattleboro Food Co-op to the Common, held placards saying, "Stop Vermont Yankee," "Not Another Chernobyl," and "Does Vermont Matter?" A child in a stroller had a sign which said: "Protect My Future."

Doug Wight, of Shutesbury, Mass., yelled, "Not in my backyard, not in country, not in my world," as he walked toward the Common, where demonstrators listened to anti-nuclear speakers.

The event was organized by Citizen's Awareness Network in Shelburne Falls, Mass., an anti-nuclear energy activism group. The demonstration was supposed to protest the Nuclear Regulatory Commission's unwillingness to perform a comprehensive, independent assessment of the Vernon nuclear power plant before its power output is upped 20 percent. But the NRC announced last week that it would conduct an independent engineering assessment.

Another demonstration to shut down Vermont Yankee down is scheduled for May 15 in Greenfield, Mass. Demonstrators are to meet up at Greenfield Common at 11 a.m. and march through the city to Energy Park.

The 33-year-old plant is among the oldest in the United States, which leads nuclear opponents to say it cannot withstand a 20 percent power boost. Vermont Yankee officials maintain that the plant is inspected regularly by the NRC and has not had any significant problems.

The missing fuel rods from Vermont Yankee are still AWOL, and the Providence Journal (registration reguired) reports officials are planning a search of waste sites in South Carolina and Washington State in an effort to track down the pieces.

Nuclear TV: PBS' Look Back at TMI, NOVA's Back to Chernobyl

(UPDATE 6/14/12: While "Meltdown at Three Mile Island" and "Back to Chernobyl" are not to my knowledge available on PBS' website, or through services like Netflix (unlike many other titles in the excellent American Experience series), with a little searching you should have little trouble finding them on YouTube in most countries.)

While you won't find many nuclear-energy related videos at your local video store (documentaries, anyway) there are some noteworthy releases available at libraries and at retail - mostly from transcription dealers and "deep-catalog" mail order outlets like Amazon.com. Being fortunate enough to have access to resources like the University of Chicago and Harold Washington libraries, I tracked down some excellent programs I'd like to recommend: but I should mention that none of the titles here are available in DVD format at this point, only as VHS tapes.

PBS' The American Experience: Meltdown at Three Mile Island (60 min.) replays the events of America's worst nuclear accident in 1979. With vintage news footage and contemporary interviews with key response team players like former Pennsylvania governor Dick Thornburgh and Attorney Governor William Scranton, this documentary is an exceptional inside look back at those panicked days near Harrisburg. This was a personally fascinating retrospective for me; not only for the content, but because I was living in Central New Jersey - less than two hours away by car from Three Mile Island - at the time of the accident.

As you watch the events unfold, what comes to mind is how unnecessary much of the TMI media confusion was in retrospect, although it may have been unavoidable at the time. For hours on end, emergency responders and the PA governor's office were unable to reach the power plant's operators, because the ordinary landlines were jammed tight with reporters' calls from around the country. No "Red Phone" hot-line was active, no two-way radio, and of course, no cell phones: the stricken plant was essentially incommunicado during some of the most crucial hours.

NOVA: Back to Chernobyl (originally aired February 14th, 1989) is an out-of-print title, but well worth tracking down, and you may likely find a copy at a library near you. Correspondent Bill Kurtis travels to the Soviet Union for a visit to the reactor site three years after the incident, and speaks with a number of survivors and eyewitnesses. Darkly humorous are the scenes with Kurtis' chatty ushanka-capped [уша́нка], Geiger counter-toting liason, Dr. Richard Wilson, who tries to reassure the journalist that the rather alarming radiation readings are nothing to worry about:

Kurtis: "Professor, how far do you think we are now from the reactor?"
Wilson: "Oh, about 30 miles."
Kurtis: "Should we check the readings?"
Wilson: "You’ll hear a high-pitched whistle as it checks the battery first. You’ll begin to hear some clicking as the readings start coming in. That’s a pretty good background, about the same as it was in Kiev. Let me just check the instrument. I’ll pull a source out of my case here."
Kurtis: "That level would seem to be the natural background."
Wilson: "That’s the natural background, but now you can test the beta ray [remember these are really particles] source, and you can hear it clicking furiously."
Kurtis: "What will the level be around the reactor itself?"
Wilson: "On this scale, around the reactor itself, we’ll find the reading to be off-scale, and we’ll have to change to the next scale. It’s about 30 times the background level around the reactor itself."
Kurtis: "Will that be any danger to us?"
Wilson: "No, you can be there for a year and get the amount of radiation that a worker is allowed to have in a year."
