Uninterruptible power supply systems are installed in the Tokai reprocessing plant in preparation for the emergency case that the commercial power supply is stopped by an accidental or intentional interruption in the supply of electricity. The uninterruptible power supply system particularly provides a temporary power source to the important devices for the radiation control of nuclear critical monitoring in the plant. Thus, the system is potentially important and essential for nuclear plants. The paper repots the current activities such as regular inspections, replacement of parts and system update, to maintain the function of uninterruptible power supply systems.

There are plural facilities having a radiation controlled area in the Tokai reprocessing plant, and an uninterruptible power supply system which considered a blackout is necessary for the power supply to each facility from the viewpoint of radiological management and nuclear material containment. In addition, at the time of the power supplying abnormality, intelligence gathering is necessary for prompt measures and restoration. In this report, the intensive monitoring system, which aimed for the unification of the power supply monitor place and the acceleration of the intelligence gathering to detect a power supply abnormality point, is described.
