Nov. 20, 2023, 2:05 p.m. Updated 35 {"title": ["", "Improving the safety and reliability of geological disposal of higher activity radioactive waste via geothermal energy co-production"], "description": ["", "\nAccording to the Nuclear Decommissioning Authority, Higher Activity Waste (HAW) includes High\nLevel Waste (HLW), Intermediate Level Waste and some Low Level Waste that is unsuitable for\ndisposal in the Low Level Waste Repository. HLW from re-processing typically occurs in liquid form\nand is converted into a solid product via a process called 'vitrification' prior to long-term storage and\ndisposal. Storage is via canisters placed into an air-cooled store until a suitable disposal route\nbecomes available. A facility would store vitrified HLW for at least 50 years before disposal. The UK\nGovernment's policy for long-term management of HAW is geological disposal, which involves\nplacing waste deep underground in a Geological Disposal Facility (GDF). A GDF includes multiple\nengineered barriers, several hundred metres underground, constructed in a suitable geological\nenvironment to ensure that the radioactivity in the waste is sufficiently isolated and contained that\nit will not cause harm to people and the environment for many hundreds of thousands of years.\nThere is currently no GDF operating in the UK, but the Government is currently developing a site\nselection process to find a volunteer host community with suitable geology. The Welsh Government\nhas also decided to adopt a policy of geological disposal for the long-term management of HAW and\ncontinues to support the policy of voluntary engagement. Scottish Government policy is that the\nlong-term management of HAW should be in retrievable near-surface facilities close to the origin of\nthe waste.\nThe temperature of HLW can rise significantly because of its radioactivity. This poses technical\nchallenges when designing a GDF, due to the impact that the released thermal energy could have on\nthe physical and chemical stability of both natural and engineered barriers, with potential\nconsequences for the GDF's long-term safety and reliability. If the original structure of the rock is\naltered, for example, it may change a groundwater movement pattern and the transport pathway\nfor radionuclides to the environment. Also, waste glass could undergo devitrification.\nThis project aims to investigate the potential benefits of controlling the temperature field in a GDF\nvia bespoke, closed-loop geothermal energy recovery systems, where the HAW would act as a hightemperature anthropogenic geothermal source. Geothermal engineering design concepts will be\ndeveloped and evaluated for potential GDF application taking account of depth, layout, geological\ncharacteristics at the site, the radioactivity inventory and the anticipated temperature field\ndevelopment over time. Their impact on the long-term integrity of GDFs will be assessed, as will the\namounts of recoverable energy for heat and/or power generation or for use to maintain stable\nrepository conditions, taking account of safety, operational and environmental constraints.\nThe project provides an ideal opportunity for a highly motivated geoscientist, physical scientist, or\nengineer to develop solutions to important problems affecting energy and the environment. The\nstudentship will benefit from the doctoral training opportunities of the Graduate School of the\ncollege of science and Engineering in Glasgow University. The work will be conducted in the School\nof Engineering in Glasgow, in collaboration with the Scottish Universities Environmental Research\nCentre in East Kilbride.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
