Fire barrier management method and system for nuclear power plant

Abstract

The invention discloses a method and a system for managing a fire barrier of a nuclear power plant. The method comprises the following steps: when the fire barrier information is updated, the newest fire barrier information is updated into a dynamic fire barrier database in real time; when the fire barrier information is updated, the newest fire barrier information is updated into a dynamic fire barrier database. Operation Risk Monitoring Steps: For each fire barrier operation, identifying an associated combination of rooms from the fire barrier information in the dynamic fire barrier database, determining a set of fire barriers existing in a combination of rooms, assessing a fire risk assessment result of the combination of rooms from a plurality of dimensions based on a type and a stateof the fire barriers in the set of fire barriers, and taking into account a superposition risk of different types of fire barrier operations in the set of fire barriers during the assessment process.The invention is convenient for the personnel of the power plant to conveniently inquire the data of the fire prevention barrier. The work efficiency of fire barrier management is improved and optimized, which can be applied to the examination and approval of fire barrier opening permit and the work platform of daily fire barrier management in nuclear power plant.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a method and system for managing fire barriers in a nuclear power plant. Background technique [0002] Fire barrier is a barrier used to limit the consequences of fire, including movable fire barriers, such as fire doors, fire dampers, equipment lifting hole covers, equipment transportation channel baffles; fixed fire barriers: such as firewall walls, floors, ceilings , Fireproof coating for steel structure, fire blocking through holes, fire blocking partition wall and electrical series fire protection package or fire damper. In nuclear power plants, fire doors are often kept open. New holes are made in fire barriers, original fire blocks, cable covers, ventilation pipes are covered with fire boards, steel structure fire protection layers, cable fire walls, and fire doors are removed. , the fire barrier needs to be managed. [0003] There are many types and numbers of fire barriers...
