Water Valve Leak Mitigation

AI Contract Overview
The Naval Nuclear Laboratory, operated by Fluor Marine Propulsion under contract with the Department of Energy, is seeking information on innovative methods to mitigate water leakage past valves during maintenance of pure water fluid systems. This request is purely for market research and not a solicitation for proposals or contracts. The goal is to identify non-intrusive solutions that prevent continuous water flow into work areas without compromising pure water chemistry or the integrity of stainless-steel components. Proposed methods must not require removal after use, must not introduce foreign materials into the system, and must either be applied externally, completely dissolve into innocuous constituents at room temperature, or otherwise avoid permanent modification of the system. The emphasis is on practical, reliable alternatives to freeze seals that reduce resource consumption during maintenance or welding operations. Responses are limited to five pages and must be submitted by September 3, 2026. This initiative is managed by Fluor Marine Propulsion, the DOE contractor overseeing the Naval Nuclear Laboratory, with inquiries directed to ATIP@unnpp.gov. The effort is classified under NAICS code 54171 and is intended to assess industry capabilities to support future procurement decisions. Interested parties should note that no costs incurred in preparing responses will be reimbursed, and submission of information does not guarantee future contract opportunities. All responses will be used solely for planning and market analysis purposes.

Full Description
THIS IS A REQUEST FOR INFORMATION ONLY. THIS IS NOT A SOLICITATION.
This notice is issued solely for informational and planning purposes. This notice does not constitute a solicitation. The Naval Nuclear Laboratory (NNL), operated by Fluor Marine Propulsion (FMP), is utilizing this request for information for market research to determine what organizations have the capability to fulfill this requirement. NNL will not be responsible for any costs incurred by interested parties in responding to this request for information.
Responses shall not exceed five (5) pages in length.
Scope:
When performing maintenance on a pure water fluid system, valves are commonly used for work area isolation. Valves that have been in-service can leak past their seats. In this case, the worker may still be protected from hazardous energy on the other side of the valve but work such as welding might not be possible if water is being continually introduced to the work area. In this case, more valves can be used if available in the system design, but if not, freeze seals are commonly used to eliminate leakage. Freeze seals can consume significant work and resources to set, so alternate means to mitigate water leakage past valves is desired.
A method to mitigate valve leak-by for the hours or days a system is open for maintenance or the time to perform a weld is desired which will not affect pure water chemistry or stainless-steel corrosion or cracking performance. The method must not introduce devices or materials that require removal from the system after repair is completed. Solutions must either be external to the system, completely dissolve into known and consistent constituents at room temperature, or otherwise non-intrusive.
