Six scientists received radiation doses of 2–4 sieverts (200–400 rem) [11] (p. 96). An experimental bone marrow transplant treatment was performed on all of them in France and five survived, despite the ultimate rejection of the marrow in all cases. A single woman among them later had a child without apparent complications.
The United States 9/11 Commission found that nuclear power plants were potential targets originally considered as part of the September 11 attacks. If terrorist groups could sufficiently damage safety systems to cause a core meltdown at a nuclear power plant, or sufficiently damage spent fuel pools, such an attack could lead to widespread ...

NRX and Zeep buildings 1945. NRX was for a time the world's most powerful research reactor, vaulting Canada into the forefront of physics research.Emerging from a World War II cooperative effort between Britain, the United States, and Canada, NRX was a multipurpose research reactor used to develop new isotopes, test materials and fuels, and produce neutron radiation beams, that became an ...
There are also events of no safety relevance, characterized as "out of scale". [37] Examples: 5 March 1999: San Onofre, United States: Discovery of suspicious item, originally thought to be a bomb, in nuclear power plant. [38] 29 September 1999: H.B. Robinson, United States: A tornado sighting within the protected area of the nuclear power plant.
It is fundamentally a Canadian design, significantly advanced from NRX. [1] It was built as the successor to the NRX reactor at the Atomic Energy Project of the National Research Council of Canada at Chalk River Laboratories. The NRX reactor was the world's most intense source of neutrons when it started operation in 1947. [2]
A clean-up crew working to remove radioactive contamination after the Three Mile Island accident. Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards".
Due to safety concerns many countries are considering thorium nuclear reactors which AECL's CANDU reactors easily convert into [9] (from uranium fuelled). Higher energy yields using thorium as the fuel (1 tonne (0.98 long tons; 1.1 short tons) of thorium produces the same amount of energy as 200 tonnes (200 long tons; 220 short tons) tons of ...
