What happens to decommissioned nuclear submarines?
When the nuclear reactors used to power submarines and aircraft carriers are disposed of, the Department of Defense maintains and monitors the radioactive parts. When submarine and aircraft carrier nuclear reactors are no longer being used, the compartments are shipped to the final disposal site on barges.

How much damage can a nuclear submarine do?
It is made up of four nuclear submarines. Each sub carries up to eight missiles on board, and each missile carries up to five nuclear bombs – or warheads – on top. Each of these bombs is around eight times as destructive as the bomb which flattened Hiroshima in 1945, killing over 140,000 civilians.
How much can a submarine carry?
SSBNs (ballistic missile submarines) can carry up to 24 missiles, which can be configured with up to 8 nuclear warheads each.
Is it possible to decommission a nuclear submarine?
Decommissioning this way is not always possible, however, says Bohmer. Some Soviet subs had liquid metal cooled reactors – using a lead-bismuth mixture to remove heat from the core – rather than the common pressurised water reactor (PWR). In a cold, defunct reactor the lead-bismuth coolant freezes, turning it into an unwieldy solid block.
What is the Submarine Dismantling Project?
The Submarine Dismantling Project (SDP) will deliver the Government’s commitment to provide a safe, environmentally responsible and cost-effective solution for dismantling 27 of the UK’s de-fuelled, nuclear powered submarines after they have left service with the Royal Navy. What is submarine dismantling? How are we undertaking the dismantling?
Are UK submarines radioactive?
UK submarines are powered by nuclear reactors. During submarine operations, nuclear reactions cause radioactive substances to be generated in the pipework and components within the reactor compartment. This requires managing after the submarine leaves service.
Are the astute and Dreadnought class submarines being decommissioned?
The Astute and Dreadnought Class submarines are not included in the 27 boats in scope of the SDP but will be considered for decommissioning in the future. On 3 April 2019 the National Audit Office ( NAO) published a report on Submarine Defueling and Dismantling.
