8 Fuel release Nuclear chain reaction Krzysztof Starosta (SFU) The Fukushima Nuclear Crisis April 11, / 23
9 Fuel release Plutonium Plutonium (Pu) is a man made, radioactive, heavy element containing 94 protons. 239 Pu is produced in fuel containing 238 U. 239 Pu is the material of choice for nuclear weapons. Mixed Oxide nuclear fuel used in one of the Fukushima reactors contains Pu/U mixture. The element of Pu is highly toxic when inhaled, (less toxic when ingested). Animal studies found that an accumulated dose of a few milligram of plutonium per kilogram of tissue is lethal. Traces of Pu were reported to be found at the Fukushima site (but not talked about recently). Krzysztof Starosta (SFU) The Fukushima Nuclear Crisis April 11, / 23
10 Fission fragments release Radio-iodine 131 I 131 I is a man made radioactive isotope of Iodine. 131 I has a half life of 8 days. 131 I is an abundant fission fragment. 131 I is used in radiotherapy of cancer. 131 I is not found in the atmosphere in normal conditions. 131 I is a good indicator of radioactivity release in reactor accidents, the signal is not obstructed by background. Iodine accumulates in the thyroid, thus large scale exposure to 131 I is a potential health hazard. Krzysztof Starosta (SFU) The Fukushima Nuclear Crisis April 11, / 23
11 Fission fragments release Radioactive 137 Cs 137 Cs is a man made radioactive isotope of Cesium. 137 Cs has a half life of 30 years. 137 Cs is an abundant fission fragment. 137 Cs is used in radiotherapy of cancer and in food irradiation. 137 Cs was not present in the environment before 1940 s when fission started to be used for nuclear power releases. 137 Cs background from nuclear weapon tests and previous nuclear accidents obscures the signal from Fukushima. Contamination with 137 Cs is long lasting. Krzysztof Starosta (SFU) The Fukushima Nuclear Crisis April 11, / 23
12 Fission fragments release Nuclear weapon tests 2000 reported tests 550 atmospheric explosions Krzysztof Starosta (SFU) The Fukushima Nuclear Crisis April 11, / 23
13 Fission fragments release Fission fragments release Release depends critically on the accident scenario. Fission fragments which exists as gases, vapours, or aerosols are released first. The Three Mile Island accident released gases only, including 131 I. The explosions and fires following the Chernobyl accident resulted in a release of 6 tons of fragmented fuel along with radioactive gases. The release of 131 I from the Chernobyl was 2.4 million times larger than from the Three Mile Island accident. The crisis management at Fukushima successfully prevented large-scale radioactivity release in the past month, however, the cooling operates under emergency conditions.
