Operational health physics experience during the JET D-T experiment

摘要

The JET deuteium-tritium experiments in 1997 (DTEl) utilised 20 grams of tritium, produced more than 2.3x10~(20) D-T neutrons, and generated peak fusion powers of 16 MW. Significant health physics input was required to measure and quantify the radiological consequences of high yield neutron and gamma production, and of processing large tritium quantities. This paper summarises the results of radiological protection monitoring carried out during the campaign.
