Safety Analysis of FFTF (Fast Flux Test Facility) Loss of Flow Without Scram Tests.

摘要

Loss of flow without scram tests were conducted at the Fast Flux Test Facility (FFTF) in July of 1986 as part of the passive safety program. This paper describes the safety analyses that were conducted in preparation for these tests. The next two papers in this session will report results of the testing and give more details. These tests involved shutting off primary coolant flow with the reactor at powers of up to 200 MW or 50% of normal full power. PPS trips were bypassed prior to the test and additional trips installed. Consequently, a detailed reevaluation of PPS system and its response to off-normal events was required.
