The BR2-Material Testing Reactor and its Major Contribution to the Reactor Material, Fuel and Safety Research

Abstract

The BR2 was shutdown at the end of June 1995 for a programme of extensive refurbishment after more than 30 years utilisation. The beryllium matrix was replaced and the aluminium vessel inspected and requalified for the envisaged 15 years life extension. Other aspects of the refurbishment programme were aimed at reliability and availability of the installations, safety of operation and compliance with modern safety standards. The reactor was restarted in April 1997.This paper deals with aspects of this refurbishment in general as well as the ongoing experimental projects in the areas of reactor material, fuel behaviour and safety research.
