Experiment prediction for Loft Nonnuclear Experiment L1-4. [PWR]

Abstract

Attached is the Experiment Prediction for LOFT Experim~nt Ll-4. This report contains the WHAM and RELAP4 ~omputer code predictions of the thermal-hydraulic response of th~ LOFT system during subcooled and saturated blowdown. We welcome your comments.

Posttest REALP4 analysis of LOFT experiment L1-3A

“…Comparison of RELAP4 predicted and experimentally measured prP.ssure in intact loop. Figures 8,9,and 10 show comparisons between calculated and measured densities in the intact loop.…”

Experiment data report for LOFT nonnuclear Test L1-4. [PWR]

“…The data, presented herein in the form of graphs in International~ System of Units (SI units), have been analyzed and qualified to the extent necessary to ensure that they are reasonable and consistent. Initial assessment of the data from this test and comparison with the experiment prediction [ 2 ] were performed in the quick look report for . nonnuclear experiment Ll-4 [ 3 ].…”

“…(1) To determine that the equipment/systems function properly (2) To demonstrate that the entire test facility can withstand the structural loads of blowdown…”

“…The accumulator, the HPIS, and the LPIS were used during•this experiment. Each system was configured to inject scaled [ 2 ] flow rates of ECC directly into the PCS cold leg.…”
