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.

Neutron kinetics investigations at the zero-power LR-0 reactor in Czechoslovakia are described. The reactor is fueled with WWER-1000 assemblies. Reactivity perturbations generated by absorber cluster movements are investigated. It can be shown that, under certain conditions, space-dependent effects can be corrected by a simple model. The experimental results are used to verify a nodal three-dimensional, two-group neutron kinetics code.
