Submarine nuclear propulsion

Rolls-Royce is a world-leader in nuclear submarine systems and support services incorporating design, procurement and operation.  For the past fifty years, we have been the Technical Authority for the UK Nuclear Steam Raising Plant (NSRP). They are responsible for powering the whole of the UK’s Royal Navy submarine fleet.

In order to fulfil our role as Technical Authority, we employ specialist and highly skilled engineers across a number of disciplines. These include; design, stress analysis, structural integrity assessment, NDE, thermo-hydraulic analysis, materials and chemistry.

Following the 2007 decision to replace the UK’s nuclear deterrent, work is progressing on developing the design requirements for a new propulsion plant. We are developing and assessing the options for this new plant. We will be using the latest nuclear engineering skills to produce a design that delivers a step change in safety and availability, whilste time reducing through-life costs. 

Our role today covers all major activities – design, project management, procurement and safety assessment. Worldwide submarine operational support is provided from Derby and through support staff at naval bases throughout the UK.
