Researchers announced earlier this month that they have completed major construction of the Gamma-Ray Energy Tracking Array (GRETA), a precision tool for gamma ray spectroscopy that, according to Paul Fallon, a researcher at University of California–Berkeley and GRETA’s project director, will be 10 to 100 times more sensitive than previous nuclear science experiments. Fallon was quoted in an August 8 article published by Lawrence Berkeley National Laboratory (Berkeley Lab)—where GRETA’s project leaders are based and GRETA was assembled.

Deep Isolation announced that it hosted its third technical workshop for the UPWARDS project, a Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) initiative aimed at developing a universal canister system (UCS) for the disposal of radioactive waste streams from advanced reactors. The workshop, held at R-V Industries in Honey Brook, Pa., focused on the large-scale manufacturing and commercialization of the UCS.

Researchers at Savannah River National Laboratory (SRNL), in concert with Lawrence Berkeley National Laboratory, Massachusetts Institute of Technology, Pacific Northwest National Laboratory, and Florida International University, are leading the Advanced Long-Term Environmental Monitoring Systems (ALTEMIS) project to move groundwater cleanup from a reactive process to a proactive process, while also reducing the cost of long-term monitoring and accelerating site closure.
