MELCOR benchmarking: The NRU full-length high-temperature-4 test
- Brookhaven National Lab., Upton, NY (United States)
The purpose of this paper is to describe a MELCOR simulation of the national research universal (NRU) full-length high-temperature-4 (FLHT-4) test and to compare results with test data and predictions from the SCDAP mechanistic code. This study provides code-to-code as well as code-to-data comparisons and will help to identify input refinements and model improvements for MELCOR. It will also help in assessing MELCOR's ability and limitations in predicting events and conditions associated with the early phase of severe core damage. This benchmarking analysis was performed as part of an overall MELCOR assessment effort being carried out for the U.S. Nuclear Regulatory Commission by Brookhaven National Laboratory. The results are considered applicable equally to the recently released MELCOR 1.8.2 as to the earlier version 1.8.1.
