Tokai Reprocess Plant (TRP) has reprocessed about 1140 tU spent nuclear fuel for 35 years. In clarification process, there are 2 kinds of valves that used under spent fuel dissolving solution environment. These valves operation data are very valuable in process handling dissolving solution because the valves are rarely used in this process. In this report, we summarize malfunctions of the valves that we have experienced until now, and explain the method of maintenance and operation management.
