- •
The MASLWR test facility has been modeled in RELAP5-SCDAP. The model is validated by comparing the simulation results with the experimental data.
- •
Results obtained from various transients show that high pressure vent and sump recirculation lines provide natural circulation flow path for long term cooling of core.
- •
New scenarios are considered in which the effect of vent and sump recirculation valves failure has been investigated.
- •
It is found from the results that continuous loss of inventory occurs due to lack of recirculation.
- •
It is concluded that the high pressure vent valves in the MASLWR safety system require more redundancy.
