EIS-0288-S1: Draft Supplemental Environmental Impact Statement

Production of Tritium in a Commercial Light Water Reactor

The Draft Supplemental Environmental Impact Statement for the Production of Tritium in a Commercial Light Water Reactor (DOE/EIS-0288-S1) supplements DOE’s 1999 Final EIS (DOE/EIS-0288), which addressed the production of tritium in Tennessee Valley Authority (TVA) reactors at Watts Bar Unit 1 in Rhea County, TN, and Sequoyah Units 1 and 2 in Hamilton County, TN, using tritium-producing burnable absorber rods (TPBARs).  After several years of production experience at Watts Bar 1, NNSA determined that it needed to produce less tritium than previously anticipated.  The new (2014) version of the Draft SEIS analyzes impacts associated with higher tritium permeation and also includes three additional alternatives that address options for providing needed tritium in the event of a reactor outage.
