    Hole found in nuclear submarine

    By ANDREW PICKEN
    SAFETY fears have been raised after a hole was discovered in the hull of a nuclear submarine berthed in the Firth of Forth.

    The hole – about the size of a fist – was found during routine checks on the decommissioned sub HMS Revenge at Rosyth Dockyard.

    The vessel is one of seven redundant nuclear subs stored at Rosyth by the Royal Navy since the early 1980s.

    The breach, discovered during a routine inspection in February, was in one of six external ballast tanks of the Polaris submarine, and was immediately sealed by Navy engineers.

    Although weapons and high-level radioactive fuel have long since been removed from the submarines, successive governments have failed to come up with a safe way of disposing of the radioactive reactor compartments, which remain at the centre of the subs.

    Navy chiefs today said the hole had been caused by microbes in the water and was repaired immediately, with no danger to the public.

    Environmentalists today said the incident was a reminder that a long-term solution for the ageing subs was needed.

    John Large, a leading UK nuclear consultant, said: "This is a significant incident as it will force the MoD finally to make a decision on this after years of humming and hawing.

    "The indecision and incompetence shown by the Ministry of Defence and Royal Navy over what to do with these boats has been absolutely staggering.

    "They've had no strategy and just to leave them afloat to rot really beggars belief.

    "You have to remember that up until 1985, the Royal Navy's policy on what to do with these old nuclear submarines was simply to dump them at sea.

    "I would imagine that when they take Revenge out of the water it will be like a car's MoT – once they find one thing wrong, they'll find others."

    The hole on HMS Revenge was discovered on one of six external ballast tanks, which are about half an inch thick compared with the inner hull, which is an inch and a half thick.

    The vessel will be moved to a dry dock next month to allow the vessel's hull to undergo a thorough examination.

    Pete Roche, an anti-nuclear campaigner and energy consultant, said: "This is very worrying news, but the problem is that nobody is coming up with any ideas on what to do with them."

    In April 1983, Britain's first nuclear sub, HMS Dreadnought, was towed into Rosyth at the end of her service and six others have followed.

    Stuart Hay, head of campaigns at Friends of the Earth Scotland, said: "This just goes to show the madness of going ahead with a new generation of nuclear power stations in the UK."

    Royal Navy spokesman Neil Smith said: "The hole was immediately plugged. There was no chance of the boat sinking and absolutely no risk to the environment or wider community."

    Fears over hole

    Fears over hole found in Fife sub

    A former nuclear submarine at Rosyth is listing slightly after a hole was discovered below the water line, BBC Scotland has learned.

    The hole has been repaired but Fife Council is demanding a decision on the long-term future of this and other retired submarines at the former base.

    The MoD said the hole was found in HMS Revenge during maintenance in February.

    It allowed seawater to leak into a ballast tank but there was no release of radioactivity.

    The reactor core of the submarine has long since been removed, but there is still radioactivity in the reactor compartment.

    The Ministry of Defence is considering how to dispose of the seven submarines at Rosyth.



    It said it was preparing a strategy for dismantling the submarines and for the interim storage of the radioactive waste. No decisions have been taken on where this will be sited.

    Councillor Tony Martin of Fife Council said it was "high time" the MoD took a decision.

    SNP defence spokesman Angus Robertson MP said the discovery of the hole was "an extremely unsettling incident".

    "It is bad enough that Scotland is being used as a dumping ground for these radioactive hulks, but we must now have solid assurances that there is no threat to public or environmental safety from their deteriorating condition," he said.

    Royal Navy spokesman Neil Smith said: "The hole was immediately plugged. There was no chance of the boat sinking and absolutely no risk to the environment or wider community."

    An MoD spokesman said: "HMS Revenge is one of seven decommissioned submarines at Rosyth Dockyard.

    "She has been stabilised, the pressure hull of the submarine has not been breached and there is no immediate danger to the rest of the structure.

    "As the submarine has been defuelled, there are no nuclear safety concerns."

      Plan B From

      Plan B From Hell

      April 17, 2008: A British SSBN (nuclear powered ballistic missile submarine) was recently discovered to have a fist sized hole in its hull. The hole, caused by corrosion, was patched, but questions were raised about why such a thing could happen. Well, it's complicated.
      The sub in question, HMS Revenge, was decommissioned in the 1980s. It's nuclear fuel, weapons and all noxious chemicals were removed. But the nuclear reactor is still radioactive, and will remain so for thousands of years. When the sub was built, in 1969, the plan was to simply sink the sub, in very deep water, when it was decommissioned. But that practice has since been outlawed by international treaty. Plan B was to cut up the decommissioned nuclear subs, and then bury the radioactive bits in a national repository for radioactive waste. But there has never been any agreement on where to locate said national repository.

      The current plan is to do nothing and wait. Plan B for that plan is to eventually (just before the old nuclear boats rot so much that they no longer stay afloat) cut them up and store the radioactive section (the reactor compartment) near the naval base (Rosyth, in Scotland) where these retired subs are tied up. The government does not want to discuss this, as the Scots would not be pleased. But possession is 9/10ths and all that. Besides, the English have been screwing the Scots for centuries, and you know how the Brits are about tradition.
