The first tritium experiment in the JET machine was carried out in November 1991. A number of different regulatory approvals were required in order to proceed with the experiment. These included radioactive discharge authorisation, approval of the safety justification and endorsement of the arrangements for accounting for tritium. Up to 90 g of tritium will be used in the full D-T phase and JET has obtained authorisation for holding this amount on site and for related radioactive discharges. The report highlights the regulatory issues involved in determining the appropriate site inventory limit. It emphasises the importance of establishing a well-founded justification in the case for radioactive discharge authorisations, and the necessity of matching the form of the compliance monitoring employed to the predicted mix of nuclides discharged. The accident analysis criteria and routine dose limits used at JET are discussed in relation to the tightening of regulatory requirements, together with QA and design standards.
