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 parameterized formulas of isomeric cross-section ratios, including two adjustable parameters for (n,2n), (n,p), (n, α) reactions at 14.5 MeV, have been derived with some approximations based on the Hauser-Feshbach theory. By fitting these formulas to available data, these parameters have been extracted, and the systematics behavior of the isomeric cross-section ratios has been studied. More accurate and reasonable predictions than before were obtained by using these parameters and the systematics formulas.
