Westinghouse teams with Nordion and PSEG to produce Co-60 at Salem
Westinghouse Electric Company, Nordion, and PSEG Nuclear announced on Tuesday the signing of long-term agreements to establish the first commercial-scale production of cobalt-60 in a U.S. nuclear reactor. Under the agreements, the companies are to apply newly developed production technology for pressurized water reactors to produce Co-60 at PSEG’s Salem nuclear power plant in New Jersey.

The decree authorizing the creation of the ITER facility was published on November 9, 2012, with the provisions adopted having been considered mostly acceptable. However, it is the first fusion facility of this kind to require a creation decree and the design of some of the systems had not yet been finalized. Moreover, while some equipment, with their associated safety requirements, are indeed classic and well known, others are uncommon and their safety requirements, although considered acceptable, are requesting justification.
Therefore, the decree was supported by about 200 requests, which have to be met during the facility startup schedule. This paper takes stock of the current situation and presents the current status of the main expected answers, taking into account the design evolution which has been further proposed by the operator (e.g., the new vacuum vessel pressure suppression system, etc.).
Some safety issues have already been considered as solved (the tokamak support design, accident within the neutral beam cell, etc.). Others are estimated not to be completely satisfactory (e.g., explosion within the vacuum vessel). Before moving on to commissioning, a few issues are still pending (detritiation system efficiency, radiation protection, etc.) and additional studies regarding the final design are expected (hot cells, tritium and waste buildings, etc.).
