NorthStar Medical Radioisotopes Phase 2

Beloit, WI: Corporate Contractors Inc built an Isotope Processing Facility for NorthStar Medical Radioisotopes, an incredibly unique project with very stringent regulatory requirements. NorthStar is the first US company in 30 years to begin 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 8 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 limestone bedrock.

Designed by Poepping, Stone, Bach & Associates, Inc. (PSBA), the building is a precast and steel construction with 40-inch concrete slabs on grade to support production hot cells weighing up to 500,000 pounds per 100 square foot area. CCI used extensive value engineering to help NorthStar save costs.
