A MARSSIM-Based Release of a Radiological Facility on the Hanford Site Using Data-Logging Instruments


G. M. Ceffalo, D. H. Denham, S. R. Reed


This paper describes the use of data-logging instruments and a location system to survey and release a portion of a former radiobiology laboratory on the Hanford Site. The building, originally intended to be disposed as 12,000 tons of contaminated waste, was selected as a candidate for release as backfill on-site. As part of Bechtel Hanford's ongoing efforts to optimize the low-level waste and cost of operations, new methods and technologies are constantly being tried. Bechtel Hanford has been implementing a Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM)-like approach to release of real property, but in a piecemeal fashion, using parts of the process in conjunction with our existing Data Quality Objectives (DQO) process. The planned demolition of the 108-F facility offered the opportunity to use the MARSSIM process from start to finish, in conjunction with new instruments and techniques.
