In February 1997, the U.S. Department of Energy, Nevada Operations Office issued the Mitigation Action Plan which addressed potential impacts described in the ''Final Environmental Impact Statement for the Nevada Test Site and Off-Site Locations in the State of Nevada'' (DOE/EIS 0243). The U.S. Department of Energy, Nevada Operations Office committed to several actions, including the preparation of an annual report, which summarizes waste shipments to and from the Nevada Test Site (NTS) Radioactive Waste Management Sites (RWMSs) at Area 3 and Area 5. This document satisfies requirements with regard to low-level radioactive waste (LLW) and mixed low-level radioactive waste (MLLW) transported to or from the NTS during fiscal year (FY) 2002.

Application of two electrical resistivity methods at the Hanford Site Mock Tank during 2002, indicate the viability of the methods as possible leak-detection tools for SST retrieval operations. Electrical Resistivity Tomography and High-Resolution Resistivity were used over a 109-day period to detect leakage of a waste simulant beneath the tank. The results of the test indicate that both of these two methods, and subset methods may be applicable to SST leak detection.
