Simulating reactor vessel meltdown and fuel lowering in concrete under serious accidents at NPPs with WWER reactors using the RASPLAV program complex

Description

The present work is devoted to numerical simulation of interaction between reactor core, reactor vessel and concrete under serious reactor accidents at nuclear power plants. The features of the serious accident simulations are considered. The possibility of keeping the meltdown core in reactor vessel is investigated theoretically and numerically. The process of interaction between the core and concrete constractions is similated numerically. 7 refs.; 22 figs
