Safety Assessment and Regulatory Requirements

Nuclear Energy Agency

Seven papers were presented in Session 1. Taking benefit of the lessons from the Barsebäck accident, many countries have improved their units since 1992. In Sweden, new strainers were developed for PWR installations which included large sacrificial strainers and self-cleaning “wing-strainer” to provide robust debris handling. The Canadian Nuclear Safety Commission (CNSC) and Canadian industry worked closely together to solve the strainer issue. AECL performed extensive tests and developed finned strainers to provide added strainer areas. Despite the issue of an official recommendation in 1998, German technical support organisations and utilities performed further experiments to demonstrate the function of the sump ...
