For reliable operation of a fast breeder reactor, the fuel elements must be resistant to breaching in slow-ramp, operational overpower transients. To determine this resistance capability of mixed-oxide fuel elements, extended overpower transient tests over a range of element design and operating conditions are being conducted in the Experimental Breeder Reactor-II (EBR-II). These tests are a part of a collaborative Operational Reliability Testing (ORT) program between the US Department of Energy and the Power Reactor and Nuclear Fuel Development Corp. (PNC) of Japan. The Phase 1 portion of the program was successfully completed in 1990; the Phase 2 program is currently in progress. Four extended overpower transient tests were conducted in the Phase-1 ORT program. The results of the first three tests, TOPI-1A, -1B and -1C, using existing preirradiated mixed-oxide fuel elements from the US breeder development program. have been reported. The results of the fourth test, TOPI-1D, using fuel elements specifically designed and fabricated for the ORT program, are the subject of this paper.
