Invented in the early 1990s, the tomographic gamma scanner is used in the nondestructive assay of radioactive waste contained in drums or cans. In the last 10 years, TGS technology has been industrialized, with systems operating in South Korea, the United States and Europe. A new ASTM International test provides users with a means of streamlining TGS procedures and practices, and it will be…

Neutron absorbers have been used for criticality control in spent nuclear fuel pools and in spent fuel transportation casks for decades. However, since the late 1980s, as spent fuel storage pools have been filled, utilities have transferred spent fuel into dry dual-purpose (storage/transportation) canisters. The neutron absorbers used in dual-purpose canisters are subjected to different operating…
