A Lengthy Entry

Since I promised a good rundown on nuclear near-misses a while back, figured it was time to get things together. Something to think about, it's not always 3-Mile-Island type incidents. AND, whether you buy it or not, we came damn close far too often to something resembling the big one. While the list below is more mainstream and not specific cold-war incidents (I'll save that for another time), all it takes is one plane to have engine trouble over enemy territory or a technical malfunction giving the impression "we" or "they" are initiating attack, prompting retaliation. An animal setting off a perimeter fence alarm at a base that was cross-wired to the attack alarm system of other bases comes to mind. That one sent planes rushing down the runways. Another is an equipment failure at a distant phone relay station that all 3 "backup" communication systems happened to run through. For all intents, the base had been wiped off the face of the earth, taking all communication links with it.
 
Early on, both the USSR and the US realized that the only disuasion from nuclear war was the understanding of mutually assured destruction (MAD). While the arms race was taking off, assuring both sides had ample and advanced weaponry to take out the largest population centers possible, the real advancements were being made on the warning and detection systems, allowing adequate time for a full scale retaliation. Both Dr. Strangelove and even Wargames use many factual incidents in a seemingly "that can't happen" storyline. So many little things are over the top you think they're fiction. The "weapons" section below gives you a taste of actual events. And consider this…the hotline to Moscow wasn't established until a year after the Bay of Pigs Invasion- 1963! That said, there are much better lists out there for cold war bafoonery and mishaps, I'll get around to those sometime.
 
People forget there are a lot of "research reactors" out there too. I've done my best to whittle down a few choice incidents from a listing that would impress and bewilder. Some accidental, some pure negligence. How do you "lose" 234 pounds of enriched uranium?? Special thanks to lutins.org for the info. Here's a taste:
 
Research Facilities:
2 September 1944
Peter Bragg and Douglas Paul Meigs, two Manhattan Project chemists, were killed when their attempt to unclog a tube in a uranium enrichment device led to an explosion of radioactive uranium hexafluoride gas at the Naval Research Laboratory in Philadelphia, PA. The explosion ruptured nearby steam pipes, leading to a gas and steam combination that bathed the men in a scalding, radioactive, acidic cloud of gas which killed them a short while later.
26 July 1959
A clogged coolant channel resulted in a 30% reactor core meltdown at the Santa Susana Field Laboratory (now known as the Boeing-Rocketdyne Nuclear Facility) in the Simi Hills area of Ventura County, California. Most of the radioactive fission products were trapped, but gasses were vented which resulted in the release of the third greatest amount of radioactive iodine-131 in nuclear history. The incident was largely covered up until a class-action suit was filed by local residents, who successfully sued for $30 million over cancer and thyroid abnormalities contracted due to their proximity to the facility.
1957
A radiation release at the the Keleket company resulted in a 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.
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.
 
 
Power Generation:
3 January 1961
A reactor explosion (attributed by a NRC source to sabotage) at the National Reactor Testing Station in Arco, Idaho, killed one navy technician and two army technicians, and released radioactivity "largely confined" (words of John A. McCone, Director of the Atomic Energy Commission) to the reactor building. The three men were killed as they moved fuel rods in a "routine" preparation for the reactor start-up. One technician was blown to the ceiling of the containment dome and impaled on a control rod. His body remained there until it was taken down six days later. The men were so heavily exposed to radiation that their hands had to be buried separately with other radioactive waste, and their bodies were interred in lead coffins.
Comment: I've seen pictures of this gruesome incident. When the vessel was blown apart, the control rod literally pinned the tech to the ceiling where he hung for days. Radiation is a relatively slow killer. Scalding, pressurized radioactive steam, not so much. If I recall, a team of men working in rotating shifts to limit exposure, were sent in to try to save the others and secure the station.
19 November 1971
The water storage space at the Northern States Power Company's reactor in Monticello, Minnesota filled to capacity and spilled over, dumping about 50,000 gallons of radioactive waste water into the Mississippi River. Some was taken into the St. Paul water system.
March 1972
Senator Mike Gravel of Alaska submitted to the Congressional Record facts surrounding a routine check in a nuclear power plant which indicated abnormal radioactivity in the building's water system. Radioactivity was confirmed in the plant drinking fountain. Apparently there was an inappropriate cross-connection between a 3,000 gallon radioactive tank.
1981
The Critical Mass Energy Project of Public Citizen, Inc. reported that there were 4,060 mishaps and 140 serious events at nuclear power plants in 1981, up from 3,804 mishaps and 104 serious events the previous year.
Comment: FOUR THOUSAND!
11 February 1981
An Auxiliary Unit Operator, working his first day on the new job without proper training, inadvertently opened a valve which led to the contamination of eight men by 110,000 gallons of radioactive coolant sprayed into the containment building of the Tennessee Valley Authority's Sequoyah I plant in Tennessee.
15-16 January 1983
Nearly 208,000 gallons of water with low-level radioactive contamination was accidentally dumped into the Tennesee River at the Browns Ferry power plant.
Comment: People are idiots.
 
Weapons:
Comment1: There's a lot here, I know. Trust me, I whittled this down!!
Comment2: This section blows my mind. The number of aircraft carrying nuclear weapons (armed or fail-safe) that crashed, had to jettison their payload, or outright disappeared is staggering! As of this date there are still nuclear "bombs" lost in the depths of the oceans and it's only a matter of time before their casings are compromised.
13 February 1950
A B-36 en route from Alaska to Carswell Air Force Base in Fort Worth, Texas, developed serious mechanical difficulties, complicated by severe icing conditions, leading to the world's first nuclear accident. The crew headed out over the Pacific Ocean and dropped the nuclear weapons from 8,000 feet off the coast of British Columbia. The weapons' high-explosive material detonated on impact, but the crew parachuted to safety.
Comment: As I mentioned in a previous post, it is possible for the explosive material to fire and not trigger a nuclear reaction if the payload is isolated, or if safety systems do their job. It IS possible to release low-levels of radiation if the core does catch fire.
10 November 1950
A B-50 en route to Davis-Monthan Air Force Base in Tucson, Arizona, was forced to jettison a nuclear weapon over the St. Lawrence River near St. Alexandre-de-Kamouraska, Canada.
10 March 1956
A B-47 with two nuclear weapons aboard disappeared over the Mediterranean Sea after flying out of MacDill Air Force Base in Tampa, Florida. An exhaustive search failed to locate the aircraft, its weapons, nor its crew.
27 July 1956
A U.S. B-47 practicing a touch-and-go landing at Lakenheath Royal Air Force Station near Cambridge, England went out of control and smashed into a storage igloo housing three Mark 6 nuclear bombs, each of which had about 8,000 pounds of TNT in its trigger mechanism. No crewmen were killed, and fire fighters were able to extinguish the blazing jet fuel before it ignited the TNT.
22 May 1957
A 10 megaton hydrogen bomb was accidentally dropped from a bomber in an uninhabited area near Albuquerque, New Mexico owned by the University of New Mexico. The conventional explosives detonated, creating a 12 foot deep crater 25 feet across in which some radiation was detected.
28 July 1957
A C-124 Globemaster transporting three nuclear weapons and a nuclear capsule from Dover Air Force Base in Delaware to Europe experienced loss of power in two engines. The crew jettisoned two of the weapons somewhere east of Rehobeth, Del., and Cape May/Wildwood, New Jersey. A search for the weapons was unsuccessful and it is a fair assumption that they still lie at the bottom of the ocean.
31 January 1958
Unbeknownst to Moroccan officials, a B-47 loaded with a fully-armed nuclear weapon collapsed and caught fire on the runway at a U.S. Strategic Air Command base 90 miles northeast of Rabat. The Air Force considered evacuating the base, but instead allowed the bomber to continue to burn for seven hours. During cleanup operations a large number of vehicles and aircraft were contaminated.
5 February 1958
A B-47 carrying a Mark 15, Mod 0, nuclear bomb on a simulated combat mission from Homestead Air Force Base in Florida collided with an F-86. After three unsuccessful attempts to land at Hunter Air Force Base in Georgia, the B-47 crew jettisoned the nuclear bomb into the Atlantic Ocean off Savannah. The Air Force conducted a nine-week search of a 3-square-mile area in Wassaw Sound where the bomb was dropped, but declared on April 16 that the bomb was irretrievably lost. The bomb was rediscovered in September 2004.
11 March 1958
A B-47 on its way from Hunter Air Force Base in Georgia to an overseas base accidentally dropped an unarmed nuclear weapon into the garden of Walter Gregg and his family in Mars Bluff, South Carolina. The conventional explosives detonated, destroying Gregg's house and injuring six family members. The blast resulted in the formation of a crater 50-70 feet wide and 25-30 feet deep. Five other houses and a church were also damaged; five months later the Air Force paid the Greggs $54,000 in compensation.
15 October 1959
A B-52 with two nuclear bombs collided in mid-air with a KC-135 jet tanker and crashed near Hardinsberg, Kentucky. Both bombs were recovered intact, but eight crewmembers lost their lives.
7 June 1960
A BOMARC-A nuclear missile burst into flames after its fuel tank was ruptured by the explosion of a high pressure helium tank at McGuire Air Force Base in New Egypt, New Jersey. The missile melted, causing plutonium contamination at the facility and in the ground water below.
21 January 1961
A B-52 bomber carrying one or more nuclear weapons disintegrated in midair following an engine fire and explosion approximately 10 miles north of Monticello, Utah, killing all five crewmembers.
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. 
8 December 1964
A B-58 slid off a runway at Bunker Hill (now Grissom) Air Force Base in Peru, Indiana. The resulting fire consumed portions of five onboard nuclear weapons, leading to radioactive contamination of the surrounding area.
5 December 1965
An A-4E aircraft accidentally fell overboard off the USS Toconderoga, with the loss of pilot LTJG D.M. Webster and a nuclear weapon. The incident, which occurred in the Pacific Ocean approximately 200 miles east of Okinawa, was not reported by the Department of Defense until 1981.
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.
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.
 
Storage/Disposal:
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.
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.
19 September 1980
An Air Force repairman doing routine maintenance in a Titan II ICBM silo in Damascus, Arkansas 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.
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.
Comment: THIRTY NINE TONS of uranium dust. That is A LOT of DUST! And 337 tons of hexafluoride up and gone? Whereabouts "completely unknown". Criminey.
