W-320 pit liner vs. coating cost risk benefit analysis
This report evaluates the costs and the risk trade-offs associated with the two pit lining or confinement options being considered as part of the Tank 241-C-106 Waste Retrieval Project. Both of these pit secondary confinement options (i.e., stainless steel pit liners and epoxy coating) can be implemented in a fashion that complies with criteria for secondary containment systems specified by the Washington Administration Codes (WAC-173-303-604). Direct life cycle costs of the two options including design, fabrication, installation, radiation, exposure, and decontamination and disposal costs are compared. Risk is expressed as probability weighted with the confinement consequences that could be mitigated by the pit liner. The risk impact of the choice of the confinement option is also evaluated in the context of the overall risk associated with the sluicing project and continued storage of the high-heat waste in the Tank 241-C-106 pending completion of the W-320 Project. The two pit secondary containment options are stainless steel line and epoxy coating.
