Preliminary Decontamination and Decommissioning Plan for the Tokamak Fusion Test Reactor

Abstract

The Tokamak Fusion Test Reactor (TFTR) Preliminary Decontamination and Decommissioning (D&D) Plan¹ was developed to provide a framework for estimating the costs and schedule for implementing a final D&D Plan. This work will be used in evaluating the future use of the TFTR Test Cell. D&D planning and estimates were generated for two cases of plasma operations for TFTR. The first scenario is for continued operation in deuterium-deuterium (D-D) plasmas and subsequent decommissioning. This scenario would require D&D to a TFTR which is slightly activated and contaminated but still with a capability for “hands-on” D&D work. The second scenario calls for deuterium-tritium (D-T) plasma operations. In this scenario TFTR becomes highly activated and contaminated with tritium. This operational scenario will result in a TFTR which will require D&D involving remote handling. The end result in either scenario would provide a Test Cell which is available for future use. This paper will discuss the D&D objectives, management, safety and technical plans, and critical assumptions made in order to develop cost and schedule estimates.
