Title: Environmental Solutions FY05: PNNL Contributions to Bechtel Hanford, Inc.

Abstract

Pacific Northwest National Laboratory provided support to Bechtel Hanford, Inc., for their work to safely demolish nuclear facilities and clean up waste sites near the Columbia River. During FY05, PNNL screened a variety of technologies to solve difficult problems. The danger of lung-scarring beryllium becoming airborne during the demolition of a nuclear fuel rod fabrication plant was addressed. For Bechtel Hanford, PNNL researchers extensively screened technologies and supported field testing of selected options. Assisted by the Laboratory's information, Bechtel Hanford staff razed the 76,000-square-feet facility near the Columbia River with no release of airborne beryllium. Removing large tanks and other equipment containing highly radioactive material from the 107-N facility continued to present challenges. The facility housed the filtration equipment for N Reactor's fuel storage basin. In FY05, PNNL identified and reviewed retrieval technologies. This work built on the evaluation criteria PNNL staff developed in FY04. In support of Bechtel Hanford's work to remediate and close the 618-7 burial ground, PNNL researchers evaluated remote technologies to characterize the waste drums as they are retrieved. One objective is to identify any drums containing Zircaloy, a zirconium alloy that can catch on fire when exposed to certain conditions. To assist in safely retrieving,more » treating, and disposing of spent nuclear fuel decladding waste in the 116-C-3 tank, PNNL identified and reviewed waste characterization, retrieval, and treatment technologies. This information was used by Bechtel Hanford staff as part of their engineering study of the situation.« less
