Assessment of in-vessel retention capability for APR1400
Description
The effectiveness of the external cooling of RPV strategy has been examined. For the key scenarios, MAAP code is used to derive the boundary condition for this investigation. Using MELTTHERM code, we examined the thermal margin for these scenarios. We found that there is enough thermal margin with the ULPU III CHF data. The effect of in-vessel injection with the external cooling of RPV is also examined. For the LBLOCA scenario, the heat flux ratio is 0.66 with the in-vessel injection. This translates into the thermal margin of 34%. For APR1400, the external cooling of RPV is a very effective severe accident management strategy in retaining corium in-vessel
