IAEA-TECDOC--1043: Technologies for gas cooled reactor decommissioning, fuel storage and waste disposal.

Technical committee meeting on technologies for gas cooled reactor decommissioning, fuel storage and waste disposal. Juelich (Germany) 8-10 Sep 1997

International Atomic Energy Agency, Vienna (Austria), IAEA-TECDOC--1043

Abstract

Gas cooled reactors (GCRs) and other graphite moderated reactors have been important part of the world's nuclear programme for the past four decades. The wide diversity in status of this very wide spectrum of plants from initial design to decommissioning was a major consideration of the International Working group on Gas Cooled Reactors which recommended IAEA to convene a Technical Committee Meeting dealing with GCR decommissioning, including spent fuel storage and radiological waste disposal. This Proceedings include 25 papers presented at the Meeting in three sessions entitled: Status of Plant Decommissioning Programmes. Fuels Storage Status and Programmes. Waste Disposal and decontamination Practices.
