Identification, Analysis and Management of Risks During the Refilling of the Temelín Nuclear Power Plant with Cooling Water

EasyChair Preprint 7808

Abstract

The critical process of nuclear power plant safety is the reactor cooling. From safety reasons, it is necessary to consider low probable unacceptable risk impacts scenarios. Analysis of data on operation of nuclear power plants showed that one of problems that creates critical situations is a long-term power black-out. The article identifies the  risks  associated with the existing way of refilling the cooling water for cooling-down of the unit on Temelín nuclear power plant, in the long-term blackout. It analyzes operating conditions and identifies critical points of cooling water supply process, i.e. problems of critical safety function. The paper shows response to extreme accident scenario based on application of feed and bleed method. It compiles a risk management plan for critical items of this process.
