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 describe a new formulation of the Monte Carlo approach to particle transport problems by defining a direct point flux estimator that extracts information from “passage” points rather than “collision” points. The approach leads directly to the radically new concept of track rotation and provides a statistical framework in which it is possible to prove the validity of the track rotation concept in spherically symmetric configurations and the validity of the compensated track rotation concept in nonspherically symmetric configurations. The approach can lead to essentially infinite gains in efficiency over conventional analog Monte Carlo methods that cannot directly estimate the flux at a point.
