Title:
NUCLEAR POWER PLANT OPERATION METHOD CONSIDERING FATIGUE STATE OF SMALL MODULAR NUCLEAR REACTOR
Document Type and Number:
WIPO Patent Application WO/2023/234640
Kind Code:
A1
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; and a flexible operation step of adjusting outputs of the remaining small modular nuclear reactors on the basis of the accumulative fatigue state derived in the diagnosing step.
