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 thermal-neutron capture cross section of 147Sm has been measured by the mass spectrometric determination of the number of 148Sm atoms formed by neutron capture. Samples of high isotopic purity were irradiated in a well-thermalized neutron spectrum for which the time-integrated neutron flux and effective neutron temperature were monitored by the burnup in 149Sm and 157Gd. A thermal-neutron capture cross section value of 75 ± 11 b was obtained from a post-irradiation 148Sm/ 147Sm ratio of 0.00025 ± 8%, at an effective neutron temperature of 127 ± 13°C.
