- Abstract
- In Japan, the experimental fast reactor Joyo has successfully completed its operation program of MK-I core (30, 75 MWt) and now preparing for the power increase to 100 MWt (MK-II core). The prototype LMBFR Monju has finished the first stage of licensing and is waiting for the second stage by the Nuclear Safety Commission. Considerations of sodium fires are very important for the design and licensing of LMFBRs. Continuing effort has been made in the study of sodium fires and their consequences since the beginning of the Japanese fast breeder reactor development program. Recent effort is mainly focussed on studies related to Monju, especially on the design and testing of primary cell liners against large sodium spills. Experimental and analytical studies on sodium fires, water release from concrete and sodium concrete reactions are conducted as a part of this study. Some extinguishing agents are also tested against sodium fires. In addition, considerable effort is being made in the development of detection systems for the small sodium leaks before a pipe rupture. This paper briefly summarizes the Japanese status of these sodium fire related activities conducted by Fast Breeder Reactor Development Project of the Power Reactor and Nuclear Fuel Development Corporation.
