UK Reactors Safety and Life Extension

Impact: Economic, Technological, Environmental


About 18% of UK electric supply is provided by 14 graphite-moderated Advanced Gas-cooled Reactors (AGRs) and 1 Pressurised Water Reactor (PWR). The AGRs are graphite-moderated, generic in design and the nuclear regulator is concerned that a common safety related fault could lead to immediately shutdown of all AGRs. The development of novel techniques at Manchester has allowed the continued operation helping the operators to establish an expected seven-year life extensions for all AGRs. For the plant operators this represents a potential income of £2.5bn per annum, avoid 30m tonnes CO2 pa and generate supply chain income within the UK of £650m pa and create or protect 2000 jobs.
