About this opportunity
The Nuclear Regulatory Commission (NRC) has issued a Special Notice announcing its intent to conduct a noncompetitive procurement of MicroShield Software and Maintenance from Grove Engineering Inc., located in Lynchburg, Virginia. This Special Notice was posted on April 16, 2026, with a submission deadline of May 1, 2026. The NRC is pursuing a single-source procurement under FAR 6.103-1, which authorizes noncompetitive contracting when circumstances demonstrate that only one source is reasonably available. No small business set-aside applies to this opportunity. The procurement is classified under NAICS code 511210 and represents a renewal of existing software licensing and support services.
The NRC intends to award a purchase order for MicroShield Annual Software and Maintenance to support its health physicists, waste managers, design engineers, and radiological engineers who rely on this comprehensive photon and gamma ray shielding assessment program. The contract period spans one year from June 10, 2026, through June 9, 2027, with four optional one-year renewal periods available. MicroShield serves critical functions including shield design, source strength estimation, exposure minimization, and shielding education, while offering integrated tools for graphing, material management, decay calculations, and nuclide data access. Grove Engineering Inc. holds exclusive copyright ownership of MicroShield and is the sole authorized provider of maintenance renewals for existing licenses, which justifies the noncompetitive procurement approach. While the submission deadline is May 1, 2026, interested parties should note that the procurement is designated as a single-source award and does not invite competitive bids.
Notice text
The U.S. Nuclear Regulatory Commission (NRC) intends to negotiate and award a non-competitive purchase order to, Grove Engineering Inc., 4925 Boonsboro Road, Lynchburg, VA 24503, for MicroShield Annual Software and Maintenance. The anticipated period of performance for the renewal is a one-year base period from June 10, 2026, through June 9, 2027, plus four one-year option periods to extend the term of the contract.
MicroShield is a comprehensive photon/gamma ray shielding and dose assessment program that is widely used for designing shields, estimating source strength from radiation measurements, minimizing exposure to people, and teaching shielding principles. MicroShield is used by NRC’s health physicists, waste managers, design engineers, and radiological engineers. MicroShield is fully interactive and utilizes extensive input error checking. The integrated tools provide results of graphing, material and source file creation, source inference with decay, projection of exposure rate versus time due to decay, access to nuclide data, and decay heat calculations. Grove Engineering owns the copyright to the MicroShield software licenses and does not currently authorize any other sources to sell maintenance renewals for their licenses.
The authority for this acquisition is FAR 6.103-1, which permits soliciting from a single source if the contracting officer determines that the circumstances of the contract action deem only one source is reasonably available to procure support for a one-year base period and four one-year option periods. The NAICS code for this acquisition is 511210.
