The Cintichem radioisotope production facility was located in Tuxedo, N.Y., 60 miles northwest of New York City, on a 100-acre site in the Sterling Forest Industrial Park. The facility was owned and operated by Union Carbide Corporation until 1984, when it was sold to Hoffman-LaRoche, a large pharmaceutical company.

The facility consisted of a 5-MWt, pool-type research reactor and production facility, connected via a 12-foot-deep, water-filled transfer canal to a bank of five adjacent hot cells. The facility began operation in the early 1960s, producing neutron-irradiated, enriched uranium target capsules. The fuel was 93 percent high-enriched uranium.

Can plant closures be an industry engagement opportunity?

New York’s Indian Point-3 was scheduled to close in April 2021.

At present, more than 20 commercial nuclear power plants in the United States have entered the decommissioning process, and many indicators point to a coming wave of additional plant closures. Indeed, with increasing numbers of plants terminating operations due to unfavorable market conditions, some voices have deemed this the “age of decommissioning.”

Regardless of whether a plant shuts its doors earlier than antici­pated or seeks a life extension through relicensing, all plants eventually close. When they do, the closure sets off a wave of economic impacts ranging from minor disruptions to severe and long-lasting harm.

Solving Sellafield’s 4 Ds problem

Though robotics solutions have been used across many industries, for many purposes, Sellafield Ltd has begun to bring robotics to the U.K. nuclear industry to conduct tasks in extreme environments. The Sellafield site, in Cumbria, United Kingdom, contains historic waste storage silos and storage ponds, some of which started operations in the 1950s and contain some of the most hazardous intermediate--level waste in the United Kingdom. There is a pressing need to decommission these aging facilities as soon as possible, as some of them pose significant radiation risk.
