As a result of the March 28, 1979, accident at Three Mile Island Unit 2 (TMI-2), significant quantities of radioactive fission products, including gases, particulates, and iodine, were released into the enclosed reactor building atmosphere from failed fuel in the reactor core. Air samples of the reactor building atmosphere showed /sup 85/Kr with a 10.7-yr half-life to be the principal remaining radionuclide. To permit less restricted access to the reactor building and to proceed toward decontamination of the TMI-2 facility, it was necessary to remove the /sup 85/Kr and to provide a suitable environment for workers. The venting was conducted between June 28 and July 11, 1980. The paper discusses reactor building air sampling, venting of the reactor building, radioactivity released to the environment, and the internal dosimetry program.
