To ask the Secretary of State for Defence for what reasons HMS Tireless was refused permission to dock in the United Arab Emirates.
To ask the Secretary of State for Defence for what reasons HMS Tireless was refused permission to dock in the United Arab Emirates.
As a matter of routine we do not discuss submarine operations, but I can give assurances that HMS Tireless' visit to the United Arab Emirates (UAE) was not for any maintenance-related issues or repairs. HMS Tireless paid a successful visit to the UAE between 15 and 20 March.

The HMS Tireless defect repair was undertaken at Devonport between February and June 2013 under the Warship Support Modernisation Initiative. Total direct costs are subject to on-going negotiations.

Paul Flynn:
The reactor in HMS Tireless was shut down on her return to Her Majesty's Naval Base Devonport to allow investigations to be carried out and repair plans to be developed. Laboratory tests confirmed that the level of airborne radioactivity in the reactor compartment was well within the normal permitted
limits for discharges to the environment. Following regulatory approval, normal alongside reactor compartment ventilation was resumed.
Repairs to HMS Tireless have now been completed and she will return to operational service in due course. It is too early to confirm what the final cost of the repairs will be.

To ask the Secretary of State for Defence what steps his Department has taken to prevent further leaks of coolant from HMS Tireless; and if he will take steps to ensure that replacement submarines are constructed in such a way as to ensure that such leaks cannot occur.

The defect investigation into the recent leak of a very small quantity of coolant on HMS Tireless and the consequent repairs have both now been completed.
The designs of Naval nuclear reactor plants are informed by lessons from earlier designs, including experience of any in-service defects. Such lessons are applied wherever practicable, including on submarines that are either being built or designed.

The Defence Nuclear Safety Regulator has permissioned three activities related to the coolant leak in HMS Tireless:
permission to vent the reactor compartment to atmosphere external to the submarine;
permission to conduct repairs at Her Majesty's Naval Base Devonport; and
permission for continued operation of HMS Tireless following completion of repairs.
The documents incorporating these permissions are being redacted and will be placed in the Library of the House as soon as they are available.
To ask the Secretary of State for Defence with reference to the answer of 15 April 2013, Official Report, column 59, on HMS Tireless, what the duration of the leak was in hours and minutes; what the volume of the lost coolant was; whether the reactor closed down or tripped...

[holding answer 13 May 2013]: The duration from the initial report of the problem to the cessation of the leak was approximately 192 hours, throughout which normal radiological monitoring of the reactor compartment was conducted.
Although the extremely sensitive radioactivity monitors indicated that elevated levels of airborne radioactivity had been detected, the coolant leak was not sufficient to produce a measurable quantity of liquid or affect the normal operation of the reactor, which was in operation throughout.
On return to Devonport the reactor compartment was surveyed and a small amount of dry surface radioactive contamination was detected in the vicinity of the leak. The area was cleaned, following standard nuclear procedures, after which no further surface contamination was detected.
No liquids associated with the leak were offloaded at Devonport or discharged at sea, and solid wastes arising from the cleaning and subsequent repair work have been removed in accordance with normal waste disposal procedures.
I am withholding the information regarding the details of the radiological inventory as its disclosure would, or would be likely to prejudice the capability, effectiveness or security of the armed forces.
To ask the Secretary of State for Defence pursuant to his answer of 4 March 2013, Official Report, column 846W, on HMS Tireless, on what date Ministers in his Department were informed of problems with the nuclear reactor cooling system on HMS Tireless; whether the incident was categorised as an...

The very small coolant leak, which was wholly contained within HMS Tireless' sealed reactor compartment, was not categorised as an abnormal event with the potential to challenge a nuclear safety system because the operating philosophy, design and safety justification for the reactor plant allows for safe management in such cases.
No members of the crew were exposed to additional or unexpected doses of radiation. As soon as the facts related to the incident had been established and assessed by the relevant Ministry of Defence authorities, Ministers were notified on 5 February 2013.
To ask the Secretary of State for Defence pursuant to the answer of 1 March 2013, Official Report, column 718W, on HMS Tireless, if he will place in the Library a copy of the report of the investigation into the recent coolant leak from the reactor of HMS Tireless conducted...

A very small coolant leak, contained within the sealed reactor compartment onboard HMS Tireless, was discovered on 4 February 2013. This presents no safety risk to members of the public, the environment or the crew.
The submarine was in international or UK territorial waters throughout her journey to Devonport, where there is a specialist submarine maintenance facility. There was no requirement to engage with or to inform the Government of the Republic of Ireland.
Repair plans are being developed and it is too early to confirm the detail or cost.

[holding answer 28 February 2013]: The recent coolant leak onboard HMS Tireless was a very small quantity and was caused by a very small defect in a system within the sealed reactor compartment of the submarine. There was no risk to the public, environment or the crew. As repair plans are currently being developed, it is too early to confirm the duration or cost of such repairs. The impact of this defect on other submarines has been fully considered and, accordingly, it is not deemed necessary to carry out additional maintenance or inspections as a result.
The Defence Nuclear Safety Regulator (DNSR) requires the Naval Reactor Plant Authorisee to investigate thoroughly incidents of this nature. Given this investigation, a further investigation by the DNSR is considered unnecessary in this instance.
I cannot comment on Tomahawk Land Attack Missile launch capability as the disclosure of this information would, or would be likely to, prejudice the capability, effectiveness or security of our armed forces.
(2) what investigations the Defence Nuclear Safety Regulator has made into the reactor coolant leak on board HMS Tireless; and if he will place a copy of the Regulator's report in the Library.
