BWR (Boiling Water Reactor) Full Integral Simulation Test (FIST) Phase 2 Test Results and TRAC-BWR (Transient Reactor Analysis Code) Model Qualification.

摘要

A full height BWR system simulator built under the Full Integral Simulation Test (FIST) program is used to investigate system responses for various transients. The test program consists of two test phases. This report provides a summary, discussion, highlights, and conclusions of the FIST Phase II tests. The Phase I tests are reported in NUREG/CR-3711, EPRI NP-3602, GEAP-30496. Eight matrix tests were conducted in the FIST Phase I. These tests investigated the large break, small break and steamline break LOCA's, as well as natural circulation and power transients. There are nine tests in Phase II of the FIST program. They include the following LOCA tests: BWR/6 LPCI line break, BWR/6 intermediate size recirculation break, and a BWR/4 large break. Steady state natural circulation tests with feedwater makeup performed at high and low pressure, and at high pressure with HPCS makeup, are included.
