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 variances of pulse fluctuations of a periodically pulsed fast reactor have been calculated. The characteristic parameters of SORA, the 1-MW pulsed fast reactor, under development by Euratom at Ispra, have been used as input data. As a result, the relative standard deviation was found to be independent of the duration of the power pulse and the pulse shape and inverse proportional to the square root of the operation power.
