1Title:  Management of key technologies in the UK Naval Nuclear Propulsion Programme Add
 Summary:  Presentation slides created by Christopher Palmer (Assistant Chief Engineer of Rolls-Royce Submarines) describing technology management in the United Kingdom's Naval Nuclear Propulsion Programme. Slide two provides the programme timeline. The first UK nuclear-powered submarine, the HMS Dreadnought, was powered by an S5W reactor and launched in 1960. The HMS Valiant, launched in 1966, was the first UK submarine powered by a Rolls-Royce pressurized water reactor plant. Both the UK and US programs are focused on building submarines that do not require refueling; slide 3 describes Rolls-Royce's Core H design, which achieves this goal. Slide 4 notes that future UK ballistic missile submarines will be powered by a next-generation plant, PWR3, which represents "a significant design evolution for the UK NNPP." In slide 5, Palmer describes the unique role of the UK NNPP in technology management, given its independent technical development and the depressed state of civilian nuclear power in the UK. He gives three examples in which the programme has taken the lead management role: "reactor core and plant performance analysis, validation and verification; major reactor plant component design; and, high integrity electrical design." Like its US counterpart (with its resources like the Bettis and Knolls laboratories), the UK NNPP has "dedicated infrastructure" that Palmer cites on slide 6. He continues by describing the collaborative efforts between the US and UK naval nuclear propulsion programs on slide 7, including the ability of both sides to gain an independent review of design approaches. In slides 10-12, Palmer describes programme challenges. In terms of decommissioned vessels, he notes that "current NNPP practice is afloat storage of defueled and decommissioned vessels (currently 17)" and that this capacity will be exhausted by 2020. This is contrast to the US approach of removing defueled reactor compartments and transporting them for storage at the Hanford Site; in part, this approach is a product of the larger number of decommissioned US nuclear submarines and ships.

2Title:  HMS Dreadnought, first British nuclear submarine Add
 Summary:  The HMS Dreadnought, the first British nuclear-powered submarine. In both her overall design and propulsion plant, the Dreadnought mirrored the six United States submarines of the Skipjack class. The Dreadnought was powered by an S5W reactor; Westinghouse worked with the British manufacturer Rolls Royce on the construction of the propulsion plant. Electric Boat provided assistance to the Vickers-Armstrong Limited shipyard for the submarine's construction.
