New reactor control system for Vengeance
By Richard Scott
The UK Royal Navy Vanguard-class nuclear-powered ballistic missile submarine (SSBN) HMS Vengeance is to be the first boat of its class to receive a new Reactor Control and Instrumentation (RC&I) system.
Installation of the new system intended to become a fleet-wide fit in due course has begun as part of Vengeance 's current Long Overhaul Period (Refuel) (LOP(R)), being undertaken by Babcock at Devonport Royal Dockyard.
Developed and manufactured by Rolls-Royce, the new RC&I system will replace the legacy Pressurised Water Reactor 2 (PWR2) RC&I system designed in the mid-1980s. The latter is increasingly costly to maintain as a result of component obsolescence.
According to Babcock and Rolls-Royce, the new 'obsolescence-tolerant' RC&I design will provide long-term support and availability of PWR2 plants. The first RC&I update installation, performed at the Shore Test Facility at the Vulcan Naval Reactor Test Establishment in the north of Scotland earlier in 2012, was led and completed by Rolls-Royce and supported by Babcock. Experience from this installation has been captured for the first-of-class fit on Vengeance now being undertaken by Babcock and supported by Rolls-Royce.182 of 327 words
