Evaluation of single failure effects during loss of coolant accidents for a VVER-440 reactor
This paper describes the results of an analysis of loss of coolant accidents (LOCA`s) for the Soviet designed, light water cooled and moderated reactors referred to as VVERS. The VVER unit selected for this analysis is designated as VVER-440 Model 213. This plant generates 440 MWe and is of current interest since fifteen are now operating and additional units are in various stages of construction within Eastern Europe and the New Independent States. In addition to the analysis of two base case LOCA`S, this paper also presents the results of several sensitivity studies related to single failures in various plant systems that have been included in the design to mitigate the effects of LOCA`s on plant and fuel system performance. Examples of the safety systems selected for these sensitivity studies include the scram system, the accumulators, and the high pressure injection system.
