Title:
PROBABILISTIC SAFETY ANALYSIS-BASED FIRE PROTECTION SELECTION METHOD AND APPARATUS FOR CABLES IN NUCLEAR POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2022/227679
Kind Code:
A1
Abstract:
A probabilistic safety analysis-based fire protection selection method and apparatus for cables in a nuclear power plant. The method comprises: performing quantitative analysis on an improved fire probabilistic safety analysis model, and calculating and obtaining a fire risk result of the nuclear power plant; obtaining an initial fire protection coated cable list, recognizing and modeling cables in the initial fire protection coated cable list in the model, and obtaining a fire risk quantification result; and determining whether the fire risk quantification result meets a probabilistic safety objective, and if not, adding other cables affected by fire to the initial fire protection coated cable list until the fire risk quantification result meets the probabilistic safety objective, so as to obtain a cable fire protection target list. By means of the method, cables having critical risks can be quantitatively recognized as cables that require fire protection, and the fire protection investment of the nuclear power plant is optimized, such that the maximum balance between safety and economy is achieved.
