Solicitation N00024-26-R-4164 is a Request for Proposal from NAVSEA HQ for the preparation, transport, dismantlement, and disposal of the ex-Long Beach (CGN 9) cruiser, including its defueled reactor plants. The scope of work requires the contractor to transport the vessel from PSNS&IMF in Bremerton, Washington, to a disposal site and perform complete dismantlement, including the scrapping of non-radioactive structures and the disposal of reactor vessels and hazardous materials. The project is scheduled for a period of performance from April 1, 2027, to September 30, 2032. The government will award one firm-fixed-price contract based on a best value tradeoff, where past performance is weighted more heavily than price, provided the technical and management approach is acceptable. The contract involves stringent security and regulatory requirements, specifically the protection of Unclassified Naval Nuclear Propulsion Information (U-NNPI) and compliance with NRC radiological regulations and DOT requirements. Offerors must provide a performance bond equal to 20 percent of the original contract price and ensure key personnel are U.S. citizens. Proposals must be submitted via PIEE in four separate volumes, including a technical proposal limited to 125 pages. Payment will be processed through the Wide Area WorkFlow (WAWF) system, with a performance-based payment structure that includes a 15 percent milestone for Navy Approval of Site Release for Unrestricted Use. Additionally, an incentive fee is applicable to CLIN 0004, subject to NRC-identified infractions and government discretion.
