MELCOR Simulation of the PBF (Power Burst Facility) Severe Fuel Damage Test 1-1

摘要

This paper describes a MELCOR version 1.7.1 simulation of the Power Burst Facility (PBF) Severe Fuel Damage (SFD) 1-1 test. The input data for the simulation was obtained from the SFD 1-1 Test Results Report and from SCDAP input. Results are presented for the transient two-phase interface level in the core, fuel and clad temperatures at various elevations in the fuel bundle, clad oxidation, hydrogen generation, fission product release, and heat transfer to the surrounding structures. Comparisons are made with experimental data and predictions from STCP and the NRC's mechanistic code SCDAP (version 18). 6 refs., 12 figs.
