Abstract

In 1996, TFTR underwent an extended outage during which large port covers were removed from the vacuum vessel in order to complete upgrades to the tokamak. Following a venting of the torus, a three tier system was developed for the outage in order to reduce and control the free tritium in the vacuum vessel so as to minimize the exposure to personnel during port cover removal and reinstallation. Several systems were implemented that successfully reduced and controlled the free tritium in TFTR and were instrumental in maintaining As Low As Reasonably Achievable (ALARA) exposures to tritium. The same systems are again being used during the safe shutdown and decommissioning of TFTR which commenced in April of 1997.
