Description/Abstract:
Revision 8 of this document addresses the need for long-term Tritium supply to fuel the nation's nuclear defense capability and the decisionmaking process for a Record of Decision to document DOE's programmatic decisions on the Tritium Supply alternatives. The programmatic environmental impact statement considers several Tritium Supply options, one of which is the Accelerator Production of Tritium (APT). This report documents the information on the APT concept. The APT Tritium Supply option consists of an accelerator than bombards a spallation target with high-energy protons. Neutrons are produced in the spallation target and are absorbed in a blanket material to produce Tritium. Two spallation targets are currently under investigation: 1) a tungsten neutron source target and 2) a lead neutron source target. In the tungsten target concept, the neutrons are captured by He-3, which is circulated through the system, thus producing Tritium. This target system is referred to as the He-3 target throughout this report. The lead target is surrounded with a Lithium-aluminum blanket and the Tritium is produced by neutron capture by Li-6. This target concept is referred to in the report as the Spallation-Induced Lithium Conversion (SILC) target. The He-3 target is the primary target while the SILC target is a backup system. The majority of the information contained in the report pertains to an APT deisgn for the production of 3/8th of the New Production Reactor (NPR) program baseline Tritium production goal. Some environmental impact information is included for a phased APT which would produce lesser amounts of Tritium. The general philosophy used in developing APT information for the impact statement was to generate bounding estimates. The information in this report includes the entire process from the production to the purification of Tritium. Recycling and purification of Tritium in the stockpile are not addressed in this report.
