Transition interface method of emergency operation regulation and severe accident management guide rule

Abstract

The invention discloses an interface management method of an emergency operation regulation and a severe accident management guide rule, which requires that in a transitory stage before a severe accident, the emergency operation regulation and the severe accident management guideline are simultaneously executed. A transitory stage master control room executes the severe accident transitory stage master control room guideline (ICRG), wherein the ICRG only comprises accident management operations related to the severe accident. The interface management method provided by the invention defines the accident management property attribution; all relative countermeasures of the severe accident management are included into SAMG (Severe Accident Management Guideline); the emergency operation regulation excludes related operations of the severe accident; the interface management method is particularly suitable for a novel power plant provided with severe accident relieving equipment; in order to ensure the effective operation of the equipment in the severe accident stage, a certain severe accident relieving equipment must execute related preparation operations before reactor core damage.

Description

technical field [0001] The invention relates to the field of accident management of nuclear power plants, in particular, to the interface management of emergency operation regulations and severe accident management guidelines. Background technique [0002] The accident management of nuclear power plants is usually divided into two stages: "prevention" and "mitigation". Before the core is damaged, that is, the prevention stage of accident management, the operator implements emergency operation procedures to bring the reactor to a controllable and stable state as much as possible; if the core is damaged (or is about to be damaged), it means that a serious accident has occurred and enters accident management. During the mitigation phase, the Technical Support Center (TSC) and the main control room implement the Severe Accident Management Guidelines (SAMG) to mitigate severe accidents, prevent or reduce the release of fission products, maintain the integrity of the containment, ...

AI Technical Summary

Problems solved by technology

However, this simple interface method has limitations. With the development of nuclear power technology, especially the systems and equipment dedicated to mitigating severe accidents are gradually being widely used in nuclear power plants, the simple interface method is difficult to meet the requirements of accident management under complex system design.
