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

The U.S. Nuclear Regulatory Commission (NRC) is issuing a pre-solicitation notice for the noncompetitive renewal of GoldSim Pro with Radionuclide Transport Module Software Upgrades and Maintenance Support Licenses. This proprietary software procurement will be conducted under the sole-source authority of FAR 6.103-1, as GoldSim Technology Group LLC is the only responsible source capable of providing the required software and support services. The NRC requires this brand-name software for performing highly flexible performance assessment modeling of complex decommissioning sites and proposed high-level waste repository sites, with the software's proprietary model file format accessible only through GoldSim's own applications. The acquisition is justified on the basis that GoldSim Technology Group, LLC does not authorize any resellers or alternative distributors for software upgrades and maintenance, leaving the NRC with no other viable procurement option. The pre-solicitation notice was posted on February 3, 2026, with a deadline of February 11, 2026, for submission of any responses or questions.

This procurement involves no set-aside designations and represents a renewal contract with the incumbent contractor, GoldSim Technology Group LLC, located at 22500 SE 64th Place, Suite 240, Issaquah, Washington 98027-8111. The pre-solicitation notice does not specify an award value or budget range for this software license renewal and maintenance support contract. The NAICS classification for this opportunity is 513210 (Software Publishers), and the Product Service Code is 7A20 (IT and Telecom—Application Development Software with Perpetual License Software). As a sole-source noncompetitive acquisition, the contract will be awarded directly to GoldSim Technology Group LLC without competitive bidding, contingent upon the company's demonstrated ability to continue meeting the NRC's technical and operational requirements.
