Transition interface method between emergency operating procedures and severe accident management guidelines

Abstract

The invention discloses an interface management method of an emergency operation procedure and a serious accident management guideline, which requires that the emergency operation procedure and the severe accident management guideline be executed simultaneously in the transitional stage before the serious accident. The main control room during the transition period implements the guidelines for the main control room during the transition period of severe accidents (ICRG), and the ICRG only includes accident management operations related to severe accidents. The interface management method proposed by the invention clarifies the nature of accident management, and puts all related countermeasures of serious accident management into SAMG, and does not include related operations of serious accidents in the emergency operating procedures. The invention is especially suitable for new power plants equipped with severe accident mitigation equipment. In order to ensure the effective operation of the equipment in the severe accident stage, some severe accident mitigation equipment must start to perform relevant preparatory operations before the core is damaged.

Description

technical field [0001] The invention relates to the field of nuclear power plant accident management, in particular to the interface management of emergency operating procedures and severe accident management guidelines. Background technique [0002] The accident management of nuclear power plants is usually divided into two phases: "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 the 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, and...

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.
