Northstar Medical Radioisotopes Phase 2

Corporate Contractors, Inc. built an Isotope Processing Facility for NorthStar Medical Radioisotopes in Beloit, a very unique project with very stringent regulatory requirements. NorthStar is one of only a few companies producing molybdenum-99 (Mo99), the parent isotope to Tc99m, without using uranium as its starting material. The 26,000-square-foot, three-level facility features dissolution hot cells, filling lines housed in an ISO class eight clean room, an automated packaging line, clean-in-place (CIP) systems and specialized storage vaults. CCI worked with NorthStar’s physicists and nuclear engineers to create labs, quality control rooms and radiation production lines. It took more than two months to hammer and grind out the site’s bedrock. The building is precast and steel construction with 40-inch concrete slabs on grade to support production hot cells weighing up to 500,000 pounds for a 100-square-foot area. CCI used extensive value engineering to save costs.
