Nuclear power plant operation method considering fatigue state of small modular nuclear reactor

Abstract

The present invention provides a method of operating a nuclear power plant, considering a fatigue state of a small modular nuclear reactor, the nuclear power plant including a plurality of small modular nuclear reactors, the method comprising: a monitoring step of monitoring a fatigue state of each of the small modular nuclear reactors; an analyzing step of, when a problematic small modular nuclear reactor, the fatigue state of which has been determined to be a predetermined level or more, is identified, analyzing whether the problematic small modular nuclear reactor is operable by considering the driving state of the problematic small modular nuclear reactor; a diagnosing step of diagnosing cumulative fatigue states of the remaining small modular nuclear reactors when the problematic small modular nuclear reactor has been determined to be inoperable.
