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 spontaneous fission branching ratios (B) of even-Z, 90 Z 100, nuclei were found to be correlated to log B = 1.6247 × Z - 1.0361(2Z - N) - 114.66. Based on this correlation, it is predicted that the isotopes 226Ra and 228Th are spontaneous fission isotopes.
