7A--GoldSim Pro with Radionuclide Transport Module and GoldSim Pro with DP Plus

The U.S. Nuclear Regulatory Commission (NRC) is seeking to noncompetitively procure the renewal of GoldSim Pro with Radionuclide Transport Module Software Upgrades and Maintenance Support Licenses with GoldSim Technology Group LLC. The NRC requires the brand name software, which has a proprietary model file format that can only be viewed, executed, and edited using the appropriate GoldSim software. The acquisition is conducted under the authority of FAR 6.103-1, and only one responsible source can satisfy the agency's requirements. • The software is used for performing highly flexible performance assessment modeling of complex decommissioning sites and proposed high-level waste repository sites. • The NRC has no other means of obtaining this software because GoldSim Technology Group, LLC, does not allow any other distributor to provide the upgrade and/or maintenance to their proprietary software. • The acquisition is for the renewal of software upgrades and maintenance support licenses.
