THE OBJECTIVES OF THE WORK ARE :
- TO PREPARE A SUMMARY OF THE RESULTS AND CONCLUSIONS OF THE PERFORMANCE ASSESSMENTS OF THE REPOSITORIES FOR HLW IN DEEP GEOLOGICAL FORMATIONS COVERING FOUR OPTIONS (CLAY, GRANITE, SALT AND THE SUB-SEABED) OF THE PAGIS PROJECT.
- TO REVIEW CRITICALLY THE BASIS, METHODS, MODELS AND DATA USED FOR THE PERFORMANCE ASSESSMENTS AND TO PREPARE A REPORT SETTING OUT COMMENTS AND SUGGESTIONS RELEVANT TO FURTHER ACTIONS OF THE PAGIS PROJECT.
THE "SUMMARY" REPORT IS INTENDED FOR PUBLICATION. THE "COMMENTS AND SUGGESTIONS" REPORT IS FOR USE BY THE COMMISSION AND THE PAGIS SECRETARIES.
The main objectives were:
to coordinate an effort at European level on performance assessment of nuclear waste disposal;
to promote a series of coordinated safety assessment studies on the most promising options to demonstrate the feasibility of the disposal practice and the capability of European teams to perform all the steps of a complex assessment on specific disposal sites;
to provide guidance for the research and development programmes on waste immobilisation and confinement;
to improve exchange among the European Community member states on the various options and variants studied;
to reinforce the confidence in, and confirm the feasibility of, the disposal practice.
