In the Chemical Processing Facility (CPF), after reconstruction was completed, the examination for advanced hydrometallurgy reprocessing was carried out from December 2002 to March 2004. In this examination,Kr were discharged from the stack. Discharge ofKr was measured and estimated by the wide range radioactive Krypton detector.GM Gas monitor of the CPF stack monitor was exchanged for the wide range radioactive Krypton detector in fiscal 1994. In discharge monitoring of this examination for advanced hydrometallurgy reprocessing,Kr gas were detected for the first time by the wide range radioactive Krypton detector of CPF. In this examination, the temporary gas monitor of the conventional GM detector was installed, and the result of measurement and inventory were compared.In this report the discharge ofKr is indicated by the wide range radioactive Krypton detector. As a result of comparative evaluation, it was confirmed that the discharge monitoring by the wide range radioactive Krypton detector was appropriate.
