NAC International announced that the Nuclear Regulatory Commission has certified a highly shielded version of the company’s OPTIMUS (Optimal Modular Universal Shipping) transportation package for radioactive materials and waste. NAC’s OPTIMUS-H is now approved under 10 CFR Part 71 with Certificate of Compliance (CoC) USA/9392/B(U)F-96, effective Aug. 5, 2024.

The OPTIMUS-H CoC follows licensing approvals of the cask in Canada and Australia. Previously, the lightweight version of the OPTIMUS package, OPTIMUS-L, received certification from the NRC and the Canadian Nuclear Safety Commission.

NAC unveiled its first OPTIMUS to the public at the 2020 Waste Management Conference in Phoenix. Since then, NAC has delivered 22 OPTIMUS-L and nine OPTIMUS-H systems to support North American packaging and transportation projects.
