MANAGEMENT OF RADIATION RISK: A GUIDE TO DEMONSTRATING ALARP FOR AN EXISTING PLANT

摘要

All industrial activity carries risks to both the public and workers from accidents. Risk management is therefore a key part of managing industrial processes. A key requirement of UK legislation is that the operator must do all that is reasonably practicable to reduce the risks from the operation of his plant, and must demonstrate that he has done so to the regulator. This imposes a continuous requirement to review the operation and maintenance of the plant to ensure the application of the principle of as low as reasonably practicable (ALARP) risks. In addition, a particular requirement for a nuclear plant is periodic safety reviews of the safety case for the plant against modern standards. In order to ensure that decisions are made in a consistent manner and can be made transparent to the regulator, Scottish Nuclear Limited (SNL) and Nuclear Electric plc (NE) have developed guidelines and supporting methodology for the assessment of risk. This guidance in our Safety Review Guidebook (SRG) for gas cooled reactors facilitates the demonstration that all that is reasonably practicable has been undertaken to reduce accident risks, or, alternatively, identifies shortfalls requiring attention.
