Krypton Recovery Development Facility (KRF) in Tokai Reprocessing Plant (TRP) has been constructed to develop recovery and storage technology of radioactive krypton (Kr) in off-gas. Since, this facility was selected as precedingly decontaminated and demolished facility in TRP decommissioning, controlled release of remaining Kr in KRF was implemented as preparation for facility decontamination and dismantling. This paper describes review of technology development in KRF and controlled release of Kr.
