The Nuclear Power Plant Accident Handbook A CNSC Emergency Operations Centre Tool

摘要

The Emergency Operations Centre (EOC) at the Canadian Nuclear Safety Commission (CNSC) in Ottawa is activated for all events which are leading or could lead to significant on-site or off-site consequences, and where the consequences of the event will be strongly affected by the operator's actions. During a nuclear emergency the CNSC's regulatory role is to provide assurance that appropriate actions are taken to limit the risk to health, safety, security and the environment. In response to the Fukushima Nuclear Emergency and the subsequent EOC response, the CNSC Fukushima Task Force recommended that hardcopy and e-version reference packages for all Canadian reactor sites be readily available to the Technical Assessment Team. The information should be easily accessible and provide pertinent information in a clear and concise manner. CSNC staff, in a cooperative agreement with Atomic Energy Corporation Limited (AECL), has begun implementing this recommendation through the development of the Nuclear Power Plant (NPP) Accident Handbook. The NPP Accident Handbook will provide readily available reference material for CNSC technical staff involved in EOC operations and enable them to find site-specific and accident-specific details in addition to providing expert advice to the EOC team during accident progression. The NPP Accident Handbook is being developed under a Graphical User Interface (GUI) software application, with the necessary drawings, databases and calculations behind the GUI. As the software will not perform detailed calculations, the use of hard engineering code is not needed. The handbook, which will have the feel of an easy to navigate webpage, is in short, a one-stop reference for nuclear accidents. This paper presents an update on the development of the NPP Handbook with the intent of sharing the lessons learned by the CNSC during the Fukushima nuclear accident.
