At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

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.
