Research Facilities

The U.S. Department of Energy spends over $4 billion each year for the restoration and management of sites contaminated by nuclear materials.
Their 2000 Federal budget noted:

"The Environmental Management (EM) program is responsible for addressing the environmental legacy resulting from the production of nuclear weapons. The nuclear weapons complex generated waste, pollution, and contamination that pose unique problems, including unprecedented volumes of contaminated soil and water, radiological hazards from special nuclear material, and a vast number of contaminated structures. Facotries, laboratories, and thousands of square miles of land were devoted to producing tens of thousands of nuclear weapons. Much of this is largely maintained, decommissioned, managed, and remediated by the EM program, which is sometimes referred to as the "cleanup program." EM's responsibilities include facilities and sites in 30 states and one territory, and occupy an area equal to that of Rhode Island and Delaware combined - or about 2.1 million acres."

21 August 1945
Louis Slotin , a physicist, was killed during the final stages of the Manhattan Project undertaken at Los Alamos, New Mexico to develop the first atomic bomb) from a radiation burst released when a critical assembly of fissile material was accidentally brought together by hand. This incident pre-dated remote-control assembly of such components, but the hazards of manual assembly were known at the time (the accident occurred during a procedure known as "tickling the dragon's tail"). A similar incident occurred nine months later (dramatized in the Hollywood movie Fat Man and Little Boy); this time, eight people were exposed, one of whom died days later. Hand-maniuplations of critical assemblies was abandoned only after another accident on 30 December 1958.

2 July 1956
Nine persons were injured when two explosions destroyed a portion of Sylvania Electric Products' Metallurgy Atomic Research Center in Bayside, Queens, New York.

1957
A radiation release at the the Keleket company resulted in a five-month decontamination at a cost of $250,000. A capsule of radium salt (used for calibrating the radiation-measuring devices produced there) burst, contaminating the building for a full five months.

30 December 1958
A nuclear criticality accident occured from a solution in a plutonium recovery operation at Los Alamos Scientific Laboratory in New Mexico. The operator died later of acute radiation sickness. The March, 1961 Journal of Occupational Medicine printed a special supplement devoted to the medical analysis of this accident.

1959
A partial sodium reactor meltdown occurred at the Santa Susana Field Laboratory in Simi Valley Hills, California.

5 October 1966
A sodium cooling system malfunction caused a partial core meltdown at Detroit Edison's Enrico Fermi I demonstration breeder reactor near Detroit, Michigan. Radioactive gases leaked into the containment structures, but radiation was reportedly contained.

1974
Whistleblowers at the Isomedix company in New Jersey reported that radioactive water was flushed down toilets and had contaminated pipes leading to sewers. The same year a worker received a dose of radiation considered lethal, but was saved by prompt hospital treatment.

1982
International Nutronics in Dover, New Jersey, which used radiation baths to purify gems, chemicals, food, and medical supplies, experienced an accident that completely contaminated the plant, forcing its closure. A pump malfunctioned, siphoning water from the baths onto the floor; the water eventually was drained into the sewer system of the heavily populated town of Dover. The NRC wasn't informed of the accident until ten months later -- and then by a whistleblower, not the company. In 1986, the company and one of its top executives were convicted by a federal jury of conspiracy and fraud. Radiation has been detected in the vicinity of the plant, but the NRC claims the levels "aren't hazardous."

1986
The NRC revoked the license of a Radiation Technology, Inc. (RTI) plant in New Jersey for repeated worker safety violations. RTI was cited 32 times for various violations, including throwing radioactive garbage out with the regular trash. The most serious violation was bypassing a safety device to prevent people from entering the irradiation chamber during operation, resulting in a worker receiving a near-lethal dose of radiation.

ca. December 1991
One of four cold fusion cells in a Menlo Park, CA, laboratory exploded while being moved; electrochemist Andrew Riley was killed and three others were injured. The other three cells were buried on site, leading to rumors that a nuclear reaction had taken place. A report concluded that it was a chemical explosion; a mixture of oxygen and deuterium produced by electrolysis ignited when a catalyst was exposed. The Electric Power Research Institute, which spent $2 million on the SRI cold fusion research, suspended support for the work pending the outcome of an investigation.

24 January 1961
A B-52 bomber suffered structural failure and disintegrated in mid-air 12 miles north of Seymour Johnson Air Force Base in Goldsboro, NC, releasing two hydrogen bombs. Five crewmen parachuted to safety, while three others died when the aircraft exploded in mid-air. The bombs jettisoned as the plane descended, one parachuting to earth intact, the other plunging deep into waterlogged farmland. To this day, parts of the nuclear bomb remain embedded deep in the muck. The area is off-limits, and is tested regularly for radiation releases. More information can be found at the Broken Arrow: Goldsboro, NC site at www.ibiblio.org/bomb/.

14 March 1961
A B-52 with nuclear bombs crashed in California while on a training mission.

13 January 1964
A B-52 with two nuclear weapons crashed near Cumberland, Maryland.

17 January 1966
A B-52 collided with an Air Force KC-135 jet tanker while refueling over the coast of Spain, killing eight of the eleven crew members and igniting the KC-135's 40,000 gallons of jet fuel. Two hydrogen bombs ruptured, scattering radioactive particles over the fields of Palomares; a third landed intact near the village of Palomares; the fourth was lost at sea 12 miles off the coast of Palomares and required a search by thousands of men working for three months to recover it. Approximately 1,500 tons of radioactive soil and tomato plants were removed to the U.S. for burial at a nuclear waste dump in Aiken, S.C. The U.S. eventually settled claims by 522 Palomares residents at a cost of $600,000, and gave the town the gift of a $200,000 desalinizing plant.

22 January 1968
A B-52 crashed 7 miles south of Thule Air Force Base in Greenland, scattering the radioactive fragments of three hydrogen bombs over the terrain and dropping one bomb into the sea after a fire broke out in the navigator's compartment. Contaminated ice and airplane debris were sent back to the U.S., with the bomb fragments going back to the manufacturer in Amarillo, Texas. The incident outraged the people of Denmark (which owned Greenland at the time, and which prohibits nuclear weapons over its territory) and led to massive anti-U.S. demonstrations. One of the warheads was reportedly recovered by Navy Seals and Seabees in 1979, but a recent (August 2000) report suggests that in fact it may still be lying at the bottom of Baffin Bay.

24 July 1969
U.S. missile production was temporarily suspended due to a serious fire at the Atomic Energy Commission's Rocky Flats plutonium bomb factory. The surrounding countryside was irradiated by plutonium, and several buildings at the factory were so badly contaminated that they had to be dismantled.

2 November 1981
A fully-armed Poseidon missile was accidentally dropped 17 feet from a crane in Scotland during a transfer operation between a U.S. submarine and its mother ship.

Submarines and Ships

1954
An experimental sodium-cooled reactor utilized aboard the USS Seawolf, the U.S.'s second nuclear submarine, was scuttled in 9,000 feet of water off the Delawre/Maryland coast. The reactor was plagued by persistent leaks in its steam system (caused by the corrosive nature of the sodium) and was later replaced with a more conventional model. The reactor is estimated to have contained 33,000 curies of radioactivity and is likely the largest single radioactive object ever dumped deliberately into the ocean. Subsequent attempts to locate the reactor proved to be futile.

October 1959
One man was killed and another three were seriously burned in the explosion and fire of a prototype reactor for the USS Triton at the Navy's training center in West Milton, New York. The Navy stated, "The explosion...was completely unrelated to the reactor or any of its principal auxiliary systems," but sources familiar with the operation claim that the high-pressure air flask which exploded was utilized to operate a critical back-up system in the event of a reactor emergency.

1961
The USS Theodore Roosvelt was contaminated when radioactive waste from its demineralization system, blew back onton the ship after an attempt to dispose of the material at sea. This happened on other occasions as well with other ships (for example, the USS Guardfish in 1975).

10 April 1963
The nuclear submarine Thresher imploded during a test dive east of Boston, killing all 129 men aboard.

1968
Radioactive coolant water may have been released by the USS Swordfish, which was moored at the time in Sasebo Harbor in Japan. According to one source, the incident was alleged by activists but a nearby Japanese government vessel failed to detect any such radiation leak. The purported incident was protested bitterly by the Japanese, with Premier Eisaku Sate warning that U.S. nuclear ships would no longer be allowed to call at Japanese ports unless their safety could be guaranteed.

21 May 1968
The U.S.S. Scorpion, a nuclear-powered attack submarine carrying two Mark 45 ASTOR torpedoes with nuclear warheads, sank mysteriously on this day. It was eventually photographed lying on the bottom of the ocean, where all ninety-nine of its crew were lost. Details of the accident remained classified until November 1993, when the Navy admitted that it had suspected all along that the Scorpion had accidentally been torpedoed by an American vessel. The nuclear material was never recovered.

14 January 1969
A series of explosions aboard the nuclear aircraft carrier Enterprise left 17 dead and 85 injured.

16 May 1969
The U.S.S. Guitarro, a $50 million nuclear submarine undergoing final fitting in San Francisco Bay, sank to the bottom as water poured into a forward compartment. A House Armed Services subcommittee later found the Navy guilty of "inexcusable carelessness" in connection with the event.

12 December 1971
Five hundred gallons of radioactive coolant water spilled into the Thames River near New London, Connecticut as it was being transferred from the submarine Dace to the sub tender Fulton.

October-November 1975
The USS Proteus, a disabled submarine tender, discharged significant amounts of radioactive coolant water into Guam's Apra Harbor. A geiger counter check of the harbor water near two public beaches measured 100 millirems/hour, fifty times the allowable dose.

22 May 1978
Up to 500 gallons of radioactive water was released when a valve was mistakenly opened aboard the USS Puffer near Puget Sound in Washington.

Nuclear Bomb Tests and Testing Facilities

5 September 1961
President Kennedy ordered the resumption of nuclear testing, "underground, with no fallout."

10 December 1961
Clouds of radioactive steam escaped from an underground nuclear test, closing several New Mexico highways.

9 December 1968
Clouds of radioactive steam from a nuclear test in Nevada broke through the ground, releasing fallout and violating the Limited Nuclear Test Ban Treaty signed 5 years earlier.

18 December 1970
An underground nuclear test in Nevada resulted in a cloud of radioactive steam to be thrust 8,000 feet in the air over Wyoming.

15 July 1999
A spokesperson for President Clinton announced that thousands of contract workers at U.S. nuclear weapons facilities, exposed to toxic and radioactive substances during the previous 50 years, could seek federal compensation for related illnesses.

Processing, Storage, Shipping and Disposal

December 1962 A summary report was presented at an Atomic Energy Commission symposium in Germantown, Maryland, listing 47 accidents involving shipment of nuclear materials to that date, 17 of which were considered "serious."

1971
After experimenting with disposal of radioactive waste in salt, the Atomic Energy Commission announced that "Project Salt Vault" would solve the waste problem. But when 180,000 gallons of contaminated water was pumped into a borehole; it promptly and unexpectedly disappeared. The project was abandoned two years later.

1972
The West Valley, NY fuel reprocessing plant was closed after 6 years in operation, leaving 600,000 gallons of high-level wastes buried in leaking tanks. The site caused measurable contamination of Lakes Ontario and Erie.

December 1972
A major fire and two explosions occurred at a Pauling, New York plutonium fabrication plant. An undetermined amount of radioactive plutonium was scattered inside and outside the plant, resulting in its permanent shutdown.

1979
The Critical Mass Energy Project (part of Ralph Nader's Public Citizen, Inc.) tabulated 122 accidents involving the transport of nuclear material in 1979, including 17 involving radioactive contamination.

16 July 1979
A dam holding radioactive uranium mill tailings broke, sending an estimated 100 million gallons of radioactive liquids and 1,100 tons of solid wastes downstream at Church Rock, New Mexico.

August 1979
Highly enriched uranium was released from a top-secret nuclear fuel plant near Erwin, Tennessee. About 1,000 people were contaminated with up to 5 times as much radiation as would normally be received in a year. Between 1968 and 1983 the plant "lost" 234 pounds of highly enriched uranium, forcing the plant to be closed six times during that period.

January 1980
A 5.5 Richter earthquake at Lawrence Livermore National Laboratory, where large amounts of nuclear material are kept, caused a tritium leak.

19 September 1980
An Air Force repairman doing routine maintenance in a Titan II ICBM silo dropped a wrench socket, which rolled off a work platform and fell to the bottom of the silo. The socket struck the missile, causing a leak from a pressurized fuel tank. The missile complex and surrounding areas were evacuated. Eight and a half hours later, the fuel vapors ignited, causing an explosion which killed an Air Force specialist and injured 21 others. The explosion also blew off the 740-ton reinforced concrete-and-steel silo door and catapulted the warhead 600 feet into the air. The silo has since been filled in with gravel, and operations have been transferred to a similar installation at Rock, Kansas.

21 September 1980
Two canisters containing radioactive materials fell off a truck on New Jersey's Route 17. The driver, en route from Pennsylvania to Toronto, did not notice the missing cargo until he reached Albany, New York.

1983
The Department of Energy confirmed that 1,200 tons of mercury had been released over the years from the Y-12 Nuclear Weapons Components Plant at Oak Ridge, Tennessee, the U.S.'s earliest nuclear weapons production plant. In 1987, the DOE also reported that PCBs, heavy metals, and radioactive substances were all present in the groundwater beneath Y-12. Y-12 and the nearby K-25 and X-10 plants were found to have contaminated the atmosphere, soil and streams in the area.

December 1984
The Fernald Uranium Plant, a 1,050-acre uranium fuel production complex 20 miles northwest of Cincinnati, Ohio, was temporarily shut down after the Department of Energy disclosed that excessive amounts of radioactive materials had been released through ventilating systems. Subsequent reports revealed that 230 tons of radioactive material had leaked into the Greater Miami River valley during the previous thirty years, 39 tons of uranium dust had been released into the atmosphere, 83 tons had been discharged into surface water, and 5,500 tons of radioactive and other hazardous substances had been released into pits and swamps where they seeped into the groundwater. In addition, 337 tons of uranium hexafluoride was found to be missing, its whereabouts completely unknown. In 1988 nearby residents sued and were granted a $73 million settlement by the government. The plant was not permanently shut down until 1989.

1986
A truck carrying low-level radioactive material swerved to avoid a farm vehicle, went off a bridge on Route 84 in Idaho, and dumped part of its cargo in the Snake River. Officials reported the release of radioactivity.

6 January 1986
A container of highly toxic gas exploded at The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma, causing one worker to die (when his lungs were destroyed) and 130 others to seek medical treatment. In response, the Government kept the plant closed for more than a year and fined owners Kerr-McGee $310,000, citing poorly trained workers, poorly maintained equipment and a disregard for safety and the environment. [See also 24 November 1992.]

1986
After almost 40 years of cover-ups, the U.S. Government released 19,000 pages of previously classified documents which revealed that the Hanford Engineer Works was responsible for the release of significant amounts of radioactive materials into the atmosphere and the adjacent Columbia River. Between 1944 and 1966, the eight reactors, a source of plutonium production for atomic weapons, discharged billions of gallons of liquids and billions of cubic meters of gases containing plutonium and other radioactive contaminants into the Columbia River, and the soil and air of the Columbia Basin. Although detrimental effects were noticed as early as 1948, all reports critical of the facilities remained classified. By the summer of 1987, the cost of cleaning up Hanford was estimated to be $48.5 billion. The Technical Steering Panel of the government-sponsored Hanford Environmental Dose Reconstruction Project released the following statistics in July 1990: Of the 270,000 people living in the affected area, most received low doses of radiation from Iodine, but about 13,500 received a total dose some 1,300 times the annual amount of airborne radiation considered safe for civilians by the Department of Energy. Approximately 1,200 children received doses far in excess of this number, and many more received additional doses from contaminants other than Iodine. [See also May 1997 and July 2000.]

1987
The Idaho Falls Post Register reported that plutonium had been found in sediments hundreds of feet below the Idaho National Engineering Laboratory, an experimental reactor testing station and nuclear waste storage site.

1988
The National Research Council panel released a report listing 30 "significant unreported incidents" at the Savannah River production plants over the previous 30 years. As at Hanford (see 1986), ground water contamination resulted from pushing production of radioactive materials past safe limits at this weapons complex. In January 1989, scientists discovered a fault running under the entire site through which contaminants reached the underground aquifer, a major source of drinking water for the southeast. Turtles in nearby ponds were found to contain radioactive strontium of up to 1,000 times the normal background level.

6 June 1988
Radiation Sterilizers, Incorporated reported that a leak of Cesium-137 had occurred at their Decatur, Georgia facility. Seventy thousand medical supply containers and milk cartons were recalled as they had been exposed to radiation. Ten employees were also exposed, three of whom "had enough on them that they contaminated other surfaces" including materials in their homes and cars, according to Jim Setser at the Georgia Department of Natural Resources.

October 1988
The Rocky Flats, Colorado plutonium bomb manufacturing site was partially closed after two employees and a Department of Energy inspector inhaled radioactive particles. Subsequent investigations revealed safety violations (including uncalibrated monitors and insufficient fire-response equipment) and leaching of radioactive contaminants into the local groundwater.

24 November 1992
The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma closed after repeated citations by the Government for violations of nuclear safety and environmental rules. It's record during 22 years of operation included an accident in 1986 that killed one worker and injured dozens of others and the contamination of the Arkansas River and groundwater. The Sequoyah Fuels plant, one of two privately-owned American factories that fabricated fuel rods and armor-piercing bullet shells, had been shut down a week before by the Nuclear Regulatory Commission when an accident resulted in the release of toxic gas. Thirty-four people sought medical attention as a result of the accident. The plant had also been shut down the year before when unusually high concentrations of uranium were detected in water in a nearby construction pit. [Also see 6 January 1986 for details of an additional incident.] A Government investigation revealed that the company had known for years that uranium was leaking into the ground at levels 35,000 times higher than Federal law allows; Carol Couch, the plant's environmental manager, was cited by the Government for obstructing the investigation and knowingly giving Federal agents false information.

31 March 1994
Fire at a nuclear research facility on Long Island, New York resulted in the nuclear contamination of three fire fighters, three reactor operators, and one technician. Measurable amounts of radioactive substances were released into the immediate environment.

May 1997
A 40 gallon tank of toxic chemicals, stored illegally at the U.S. Government's Hanford Engineer works exploded, causing the release of 20,000-30,000 gallons of plutonium-contaminated water. A cover-up ensued, involving the contractors doing clean-up and the Department of Energy, who denied the release of radioactive materials. They also told eight plant workers that tests indicated that they hadn't been exposed to plutonium even though no such tests actually were conducted (later testing revealed that in fact they had not been exposed). Fluor Daniel Hanford Inc., operator of the Hanford Site, was cited for violations of the Department of Energy's nuclear safety rules and fined $140,625. Violations associated with the explosion included the contractor's failure to assure that breathing devices operated effectively, failure to make timely notifications of the emergency, and failure to conduct proper radiological surveys of workers. Other violations cited by the DOE included a number of events between November 1996 and June 1997 involving Fluor Daniel Hanford's failure to assure adherence to PFP "criticality" safety procedures. ("Criticality" features are defined as those features used "to assure safe handling of fissile materials and prevention of...an unplanned and uncontrolled chain reaction that can release large amounts of radiation.") [See also 1986 and July 2000.]

8 August 1999
The Washington Post reported that thousands of workers were unwittingly exposed to plutonium and other highly radioactive metals over a 23-year period (beginning in the mid-1950's) at the Department of Energy's Paducah Gaseous Diffusion Plant in Kentucky. Workers, told they were handling Uranium (rather than the far more toxic plutonium), inhaled radioactive dust while processing the materials as part of a government experiment to recycle used nuclear reactor fuel.

June 2000
U.S. Senator Mike DeWine (R-OH) led a field senate hearing regarding workers exposed to hazardous materials while working in the nation's atomic plants. At the hearing, which revealed information about potential on and off-site contamination at the Portsmouth Gaseous Diffusion Plant in Piketon, Ohio, DeWine noted, "We know that as a result of Cold War efforts, the government, yes, our federal government, allowed thousands of workers at its facilities across the country to be exposed to poisonous materials, such as beryllium dust, plutonium, and silicon, without adequate protection." Testimony also indicated that the Piketon plant altered workers' radiation dose readings and worked closely with medical professionals to fight worker's compensation claims.

July 2000
Wildfires in the vicinity of the Hanford facility hit the highly radioactive "B/C" waste disopsal trenches, raising airborne plutonium radiation levels in the nearby cities of Pasco and Richland to 1,000 above normal. Wildfires also threatened the Los Alamos National Laboratory in New Mexico and the DOE's Idaho National Engineering and Environmental Laboratory. In the latter case, the fires closely approached large amounts of stored radioactive waste and forced the evacuation of 1,800 workers. [See also 1986 and May 1997.]

YMP Editor: (Addition/May 26, 2002)
STRONTIUM - What is it? There are two types.
(#1) = Strontium: A soft malleable ductile metalic element of the alkaline-earth group occuring only in combination and used especially in color TV tubes, in crimson fireworks, and in the production of some ferrites.
What is a FERRITE?
Any of several magnetic substances that consist essentially of an iron oxide combined with one or more metals (as manganese, nickle, or zinc), have high magnetic permiability and high electrical resistivity, and are used especially in computer memories. Also, a solid solution in which alpha iron is the solvent.

(#2) = Strontium 90: A heavy radioactive isotope of strontium having the mass number of 90 that is present in the fallout from nuclear explosions and is hazardous because like calcium it can be assimilated in biological processes and deposited in the bones of human beings and animals; called also: radiostrontium.
