Report
New technical solutions elaborated in WWER reactor NPS designs on preventing the severe accidents and their control
Description
The most typical accidents at NPP with WWER-1000 type reactors are outlined. Measures on preventing accidents and measures on severe accidents control and mitigation of their consequences are analyzed. The first group of the measures includes use of reactors with improved nuclear physical features, use of primary circulating pumps with minimum seal leakages, use of safety channel element availability monitoring system. The second group of measures envisages use of passive residual heat removal system, passive core flooding system, system of quick boron injection into the first circuit, system of pressure shedding and cleaning of releases, hydrogen suppression system. 4 figs
