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.

Compatibility of monolithic silicon carbide (SiC) with ternary lithium ceramics (Li1-xAlO2-y, Li2-xTiO3-y, Li2-xZrO3-y and Li4-xSiO4-y) under irradiation of neutrons at high temperatures was studied. Disk samples of SiC in contact with sintered ternary lithium ceramics were irradiated in High Flux Isotope Reactor (HFIR) at 800 °C to 5.9 displacements per atom (dpa). Chemical reactions of SiC as determined by appearance of the surface were relatively less significant for the systems of SiC/Li1-xAlO2-y and SiC/Li2-xTiO3-y, whereas some bonding likely due to chemical reaction between SiC and the lithium ceramics and broken samples were observed in the systems of SiC/Li2-xZrO3-y and SiC/Li4-xSiO4-y. The effect of lithium burnup due to the (n, ) nuclear reaction was also examined by using samples of lithium ceramics whose lithium ratio was hypo-stoichiometric in the fabrication process. More reaction products were observed on the surface of -SiC in contact with Li1-xAlO2-y having the lower lithium ratio (Li/Al). It was considered that the formation of LiAl5O8 phase due to lithium loss could deteriorate the compatibility of the SiC - Li1-xAlO2-y system.
