Three Mile Island Unit 2 (TMI-2): reactor building venting experience
A major step in the cleanup of the damaged Three Mile Island Unit 2 (TMI-2) plant was conducted in June and July of 1980. This step was the venting of radioactive gases, mostly Krypton 85 (Kr-85) from the TMI-2 reactor building. After a wait of more than 7 months from the time of submitting the request to the Nuclear Regulatory Commission (NRC), GPU vented about 44,000 curies of Kr-85, about one curie of Tritium, and trace amounts of particulate activity. The venting was conducted from June 28 to July 11, without any major problems. The maximum integrated doses that were calculated for any given sector off-site were 4.5 mrem skin dose and 0.045 mrem whole body dose. Actual measured doses off-site were less than the maximum calculated doses.
