Activation measurements on the Tokamak Fusion Test Reactor (TFTR)
- 1. Princeton Plasma Physics Lab., Princeton, NJ 08544
Description
The Tokamak Fusion Test Reactor (TFTR) is the largest operating magnetically confined fusion research device in the United States. In the deuterium-deuterium (D-D) mode it has set new neutron production records in its ''super-shot'' regime on the order of 10/sup 16/ n/sec. The production of small quantities of tritium during these runs also means that some deuterium-tritium (D-T) reactions produce 14 MeV neutrons and thereby increase activation. This paper discusses activation measurements and how the observed radionuclides compare to predictions made for TFTR. Presently, Mn-54, Co-58, Mn-56 and Co-60 are now detectable, along with Br-82 from G-10 electrical insulation. Therefore, procedures for access to the tokamak area now incorporate health physics considerations
