概要
Many number of rechargable batteries are installed as an electrical power supply system to maintain the function of the RoNNasho Reprocessing Plant. These batteries have an important role to Neep the safety of the plant, so at the case of loss of normal and external alternating power supply, electrical circuits should be switched to battery powered system automatically and instantaneously. Exchange and replacement plan of these batteries are scheduled mainly based upon the capacity test data checNed by battery vendors, expected life length,and the periodical inspection data. However it is difficult to remove all batteries from circuits and send them to battery vendor’s facilities at the same time to diagnose their capacity whether plant is in service or not. The authors introduce the advanced inspection technology as called “Short time discharge voltage measureme of batteries“ which realize to diagnose the capacity of all them without removing off from the circuits.
