The Ship/Submarine Recycling Program (SRP) is the process the United States Navy uses to dispose of decommissioned nuclear vessels. SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere.
Spent nuclear fuel is shipped by rail to the Naval Reactor Facility in the Idaho National Engineering and Environmental Laboratory (INEEL), located 67 kilometers (42 miles) northwest of Idaho Falls, Idaho, where it is stored. The fuel is not reprocessed.
At PSNS the SRP proper begins. A submarine is cut into three or four pieces: the aft section, the reactor compartment, the missile compartment if one exists, and the forward section. Missile compartments are dismantled according to the provisions of the Strategic Arms Reductions Treaty. Reactor compartments are sealed at both ends and shipped by barge and multiple-wheel high-capacity trailers to the Department of Energy's Hanford Nuclear Reservation in Washington state where they are buried. The burial trenches have been evaluated to be secure for at least 600 years before the first pinhole penetration of some lead containment areas of the reactor compartment packages occurs, and several thousand years before leakage becomes possible.
Until 1991, the forward and aft sections of the submarines were rejoined and placed in floating storage. Various proposals for disposal of those hulks were considered, including sinking them at sea, but none were economically practical. All required removal of the numerous polychlorinated biphenyl products (PCBs) on board, which are considered hazardous materials by the Environmental Protection Agency and United States Coast Guard. In order to reduce the costs, the remaining submarine sections are recycled, returning reusable materials to production. In the process of submarine recycling, all hazardous and toxic wastes are identified and removed, reusable equipment is removed and put into inventory. Scrap metals and all other materials are sold to private companies or reused. The overall process is not profitable, but does provide some cost relief. Disposal of submarines by the SRP costs the US $25-50 million per submarine.
By the end of 2005, 195 nuclear submarines had been ordered or built in the US (including the NR-1 Deep Submergence Craft and Virginia, but none of the later Virginias). The last of the regular Sturgeon attack boats, L. Mendel Rivers was decommissioned in 2001, and Parche, a highly-modified Sturgeon, was decommissioned in 2004. The last of the "41 for Freedom," Kamehameha was decommissioned in 2002. Decommissioning of the Los Angeles boats began in 1995 with the badly-damaged Baton Rouge. Additionally, a handful of nuclear powered cruisers have entered the program, and their dismantlement is ongoing. Note that the United States operates nuclear powered aircraft carriers, but as of 2006 no nuclear powered carrier has been decomissioned. Hulks waiting or already processed by the recycling program include:
| Ship Name (Hull Number) | Start Date | Completion Date |
|---|---|---|
| ex-Long Beach (CGN-9) | 1 October 2008 | Not started |
| ex-Bainbridge (CGN/DLGN-25) | 1 October 1997 | 30 October 1999 |
| ex-Truxtun (CGN/DLGN-35) | 1 October 1997 | 28 April 1999 |
| ex-California (CGN/DLGN-36) | 1 October 1998 | Ongoing |
| ex-South Carolina (CGN/DLGN-37) | 1 June 2007 | Not started |
| ex-Virginia (CGN/DLGN-38) | 1 October 1999 | Ongoing |
| ex-Texas (CGN/DLGN-39) | 1 October 1999 | Ongoing |
| ex-Mississippi (CGN/DLGN-40) | 1 October 2004 | Ongoing |
| ex-Arkansas (CGN/DLGN-41) | Unknown | Unknown |
A dagger (†) after a completion date indicates that portions of the hulk were preserved as memorials. See the individual articles for details.
Submarines marked cancelled were scheduled to be inactivated and recycled, but instead will be refueled and given a comprehensive overhaul.
Because the program is underway, this list is almost certainly incomplete.
Note for ships marked with refit: Sam Rayburn (SSBN-635) was converted into a training platform — Moored Training Ship (MTS-635). Sam Rayburn arrived for conversion on 1 February 1986, and on 29 July 1989 the first Moored Training Ship achieved initial criticality. Modifications included special mooring arrangements including a mechanism to absorb power generated by the main propulsion shaft. Daniel Webster (SSBN-626) was converted to the second Moored Training Ship (MTS-2 / MTS-626) in 1993. The Moored Training Ship Site is located at Naval Weapons Station Charleston in Goose Creek, South Carolina. Sam Rayburn is scheduled to operate as an MTS until 2014 while undergoing shipyard availabilities at four year intervals.
