College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

The effects of post-welding heat treatment (PWHT) at temperatures ranging from 640°C to 750°C for 1 h on the mechanical and metallographical properties of a dissimilar-metal electron beam weld (EBW) joint of reduced activation ferritic/martensitic steel, F82H, and SUS316L austenitic stainless steel were investigated. The EBW joint is demarcated into five regions: the base metal of F82H (F82H-BM), the heat-affected zone of F82H (F82H-HAZ), the interlayer at the edge of F82H-HAZ (IL), the weld metal (WM), and the base metal of SUS316L (SUS316L-BM). No hardening resulting from welding and no significant change in the hardness resulting from PWHT above 640°C were observed in the F82H-BM, SUS316L-BM and WM. However, a significantly higher hardness was observed in the as-welded F82H-HAZ and IL than in other regions, and a significant reduction in hardness occurred in F82H-HAZ and IL, as a result of PWHT above 640°C. Irradiation hardening after PWHT at 720°C was investigated using proton-irradiation at 300°C up to 0.1 and 1 dpa. The irradiation hardening of the WM, IL and SUS316L-BM, which was less than that of the as-received SUS316L, was much larger than that of F82H-HAZ and F82H-BM.
