Westinghouse, Nordion, and PSEG team up to produce Co‑60 in the United States
This past January, Westinghouse Electric Company, Nordion, and PSEG Nuclear formalized agreements to implement newly developed cobalt-60 production technology at Units 1 and 2 of PSEG’s Salem nuclear power plant in New Jersey, with the Co-60 to be supplied to Nordion. Through an ongoing joint initiative, the companies aim to harness U.S. pressurized water reactors to produce a key medical isotope and build the first commercial-scale Co-60 production platform in the United States.

The General Atomic Neutron Velocity Selector has been used to study the details of neutron scattering in reactor-grade graphite. The scattering into various angular directions between 30 and 120° has been studied for incident neutrons with energies ranging up to 0.611 eV. The energy-transfer cross sections, corrected for plural scattering effects, have been evaluated to provide data in regions of large energy and momentum transfers not previously available and not readily accessible to experimenters using a reactor as a source of neutrons. The results are quite definitive and, when compared to the best available theory, indicate some regions of good agreement and some regions where a more complete theoretical treatment would be useful.
