Critical Control Valves and their Reliability During Seismic Events

Abstract

The revitalization of nuclear industry in world comes with increasing safety concerns and regulations. This paper focuses on the study of reliability of controlling valves regulating the cooling water flow around a nuclear core. The cooling process of a nuclear core is of high importance when considering nuclear power plant safety. The main concern for the valve’s construction and operation is its survivability and continued functioning at all times. The main purpose of this paper is to enable the nuclear industries in Canada to gain an overview of the valve design and its capability in withstanding unforeseen condition such as seismic events.
