Nuclear Research Reactor Decontamination & Decommissioning

University Of Washington
Seattle, Washington

ENERCON and its partner, LVI Services, INC, successfully completed the D&D of the University of Washington Research and Training Reactor in Seattle, Washington in October 2006. ENERCON received notice in January 2007 that the facility was recommended for unrestricted release by the NRC's independent verifier, Oak Ridge Institute of Science and Education (ORISE). ENERCON was responsible for the radiation safety, dosimetry, health and safety, waste management and quality control programs. In addition, ENERCON developed and implemented the Final Status Survey (FSS) Plan and authored the FSS report. Radiological Decontamination & Decomissioning (D&D) activities began in early April 2006 and were conducted through the summer of 2006. The D&D activities resulted in the generation of 1677 cubic feet of Low Level Radioactive Waste and 32 cubic feet of Mixed Waste which were disposed at U.S. Ecology in Hanford, Washington and Energy Solutions in Clive, Utah, respectively. Final Status Surveys (FSS) in support of license termination commenced in August 2006 and were completed in the beginning of October 2006. The FSS was planned and conducted in accordance with methodologies established in NUREG/CR-5849. The project was completed on schedule and on budget. The project was completed with a total collective dose of 1.491 person-REM (30% of the collective dose estimated in the Decommissioning Plan). License Termination for the Reactor was announced by the NRC in August 2007.
