Jerry Hyde DOE HQ, EM-50 Frank Crimi Lockheed Environmental Systems, NRC Subcommittee on D&D Trish Baisden Lawrence Livermore National Laboratory, NRC Subcommit tee on D&D BACKGROUND INFORMATION For over 40 years, the Hanford Site manufactured nuclear materials for the nation's defense programs. To assist in this nuclear materials production, nine water-cooled graphite-moderated plutonium reactors were constructed along the Columbia River by the U.S.

The resulting mound would be topped with an engineered barrier designed to limit water infiltration to 0.1 centimeter per year. On the basis of a review of environmental impacts, total project cost, and the results of the public review process, the preferred option selected in the ROD was safe storage of the eight reactors followed by deferred one-piece removal.

The last reasons for selecting C-Reactor were that the EIS ROD for the proposed D&D approach had been finalized, and the conceptual design and detailed radiological and hazardous materials characterization had been completed to implement the plan. Note: Although Fluor-Daniel is the Site Management and Integration Contractor (I/C)

Waste management, including volume reduction, packaging, transportation, and disposal; · Safe storage enclosure system design, including roof, penetration seals, electrical and remote monitoring, and ventilation; and · Site restoration. In April 1996 Delphinus Engineering delivered to BHI the CDR, which included the following deliverables: Conceptual design; Engineering studies; Long-lead-time procurement items; Preliminary hazards analysis; Work breakdown structure and WBS dictionary; and Conceptual cost estimate and project schedule.

C-Reactor is one of eight reactors slated for safe storage followed by deferred one-piece removal. Developing new, practical technologies in the areas of characterization, decontamination, demolition, waste disposal, facility stabilization and worker health and safety during the C-Reactor project hopefully will reduce D&D costs, reduce health and safety risks, and expedite the safe storage of the other surplus reactors.

In the CDR engineering studies, potential technologies were evaluated for the various activities identified (e.g., decontamination versus contaminant removal, demolition techniques, etc.~. A description of each technique considered was included along with its potential application, applicability, cost, and availability.

These organizations are responsible for providing supporting cost estimates as well as collecting actual cost data. BHI executes the D&D activities using Hanford Plant Force union workers, except for construction work, which falls under the requirements of the DavisBacon Act.

The Hanford Environmental Remediation Disposal Facility (ERDF) is also permitted as a CERCLA facility, although it was designed to RCRA criteria.

From page 67... ...
Hanford has identified six focus areas for which innovative technologies will be selected, used, and evaluated. The Hanford focus areas are characterization, decontamination, demolition, waste disposition, facility stabilization, and worker health and safety.

BHI is following the contractual requirements of its contract with DOE-RL by including appropriate contract clauses and requirements to the members of the TAT and other subcontractors. Product liability and intellectual property rights have not been barriers in setting up the C-Reactor LSDP.
