Proven

  • GE began developing sodium cooled reactors in the late 1940s
  • The technology utilized by PRISM is based on more than 30 years of development

Safe

  • Features advanced passive safety systems and design prevents loss of coolant accident
  • PRISM supports non-proliferation efforts – once used in the reactor, plutonium takes on qualities that make it effectively unusable for other purposes

Clean

  • Recycles hazardous nuclear waste – reprocessed uranium and unused fuel from past nuclear reactor programs – to generate electricity
  • Decreases the environmental concerns of legacy reprocessing while generating carbon-free electricity

Cost-effective

  • Uses a highly efficient fuel manufacturing process
  • Because PRISM can process fuel materials faster than alternatives, it requires a smaller plant design, resulting in lower costs

Low carbon electricity

  • A PRISM plant is designed to generate over 600MW of predictable, controllable, low carbon electricity for the grid – enough to power 600,000 homes each year

Flexible

  • Potential exists for PRISM to evolve beyond dispositioning plutonium
  • Could recycle hazardous nuclear waste, including reprocessed uranium and unused fuel from past nuclear reactor programs


PRISM’s solution to managing the UK’s plutonium stockpile

Plutonium Reuse

large

PRISM offers an efficient, clean, cost-effective way to rapidly manage the UK’s plutonium stockpile, while also generating low-carbon electricity. The benefits of building a PRISM plant at Sellafield are significant.

  • PRISM would support the development of a world class skills base and create the opportunity for the UK to become a global center of engineering excellence and low carbon innovation
  • West Cumbria would be positioned as a global hub for innovative next generation technology underpinned by local research and development
  • Would create many hundreds of new jobs over a long period of time, moving Sellafield beyond decommissioning and waste management and into the next generation of nuclear power technologies
  • PRISM is the only existing technology capable of processing all the stored plutonium oxide powder in the UK civil plutonium stockpile
  • Over its estimated 60-year operating life, a PRISM plant is capable of dispositioning the entire UK plutonium stockpile; using more PRISM power blocks will result in more energy extracted from this energy resource
  • PRISM could conceivably make the entire UK plutonium stockpile proliferation resistant in 20 years (significantly faster than any alternatives)
  • PRISM plants could, if they were to fission all the plutonium currently stored at Sellafield, meet all of the UK energy needs for the next 100 years
