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.

We have measured the spectra of neutrons and secondary gamma rays emerging from a liquid-nitrogen sphere of 129.3-cm radius with a 14-MeV neutron source at its center. Time-of-flight techniques were used to obtain the detailed data and to minimize background. To compare the measurements with calculations, we folded the detector efficiencies and appropriate experimental parameters into the calculated output of TARTNP, a coupled neutron-photon Monte Carlo transport code utilizing the Lawrence Livermore Laboratory Evaluated Neutron Data Library, September 1975. The calculated neutron spectra show fair agreement with the measurements, and the calculated gamma-ray spectrum is nearly the same as the corresponding measured spectrum. The total biological dose derived from these measurements is in good agreement with the calculations and provides a benchmark for a dose-versus-range curve obtained by TARTNP calculations.
