This effort requires close, regular communication and coordination with program personnel from NNSA and the Tennessee Valley Authority (TVA). TVA is a cooperating agency in preparing the SEIS because tritium-producing rods are being irradiated in its Watts Bar Unit 1 reactor. Once the tritium-producing rods are irradiated in the TVA reactors, they are removed and sent to the U.S. Department of Energy's Savannah River Site, where the tritium is extracted. Each tritium-producing rod makes about 10,000 curies of tritium.
After publishing the 1999 Environmental Impact Statement (EIS) for the Production of Tritium in a Commercial Light Water Reactor (CLWR), which had assumed permeation of tritium through the walls of the tritium-producing rods in the reactor at 1 curie/per rod/year, it was found that the actual permeation rate is 3–4 curies/per rod/year. Primarily for this reason, the National Nuclear Security Administration (NNSA) is preparing a Supplemental EIS. Additionally, while the original EIS analyzed the impacts of up to 3,400 tritium-producing rods in a reactor, the current SEIS analyzes the environmental impacts associated with a maximum of 2,500 rods per reactor. To manage all aspects of the preparation of this complex SEIS, NNSA relied on Dade Moeller, an NV5 Company,* as a member of JAD Environmental, LLC, to:
- Prepare the project management documents, including a Project Management Plan, Quality Assurance (QA) Plan, and Administrative Record Plan
- Draft the Notice of Intent to prepare the SEIS
- Manage preparation of the materials and logistics for public scoping meetings, including responses to comments received both at the meetings and during the public comment period
- Manage the efforts of a significant number of technical experts in all disciplines necessary for preparation of such a complex EIS, including all impacts of normal operations such as air, surface, and groundwater impacts, accident analysis, and transportation impacts
