NDA Technical Assurance Manager Darrell Morris joined international counterparts at WM Symposia 2018 to embrace the growing opportunities for using robots in nuclear decommissioning, and for adapting robotic technologies from other industries.
Nucleargraduate Arun Khuttan, whose training included eight months at the NDA and is now seconded to Moltex Energy, outlines an inspirational week at the annual Waste Management Symposia (WMS) in Phoenix, US.
Mae’r blog yma yn bwrw golwg ar fy mhrofiadau ar stondin arddangos RWM yn Ffair Big Bang yn ystod dau ddiwrnod olaf y digwyddiad.
O fewn RWM mae yna is-grwpiau a thimau gwahanol. Dwi’n ffisegydd siartredig, a fy ngwaith i yw dangos na fydd Cyfleuster Gwaredu Daearegol (GDF) yn achosi niwed i bobl na'r amgylchedd. Mae gwaredu daearegol yn cynnwys ynysu a gosod gwastraff ymbelydrol mewn daeargelloedd a thwneli, yn ddwfn o dan ddaear, rhwng 200m a 1000m o dan yr wyneb. Mae hyn yn atal ymbelydredd rhag cyrraedd yr wyneb mewn lefelau a allai achosi niwed. Caiff gwastraff ymbelydrol solet ei becynnu mewn cynwysyddion diogel sydd wedi’u peiriannu, a wneir fel arfer o fetel neu goncrid, a'u gosod mewn ffurfiant creigiau sefydlog, gyda'r cynwysyddion wedi'u hamgylchynu gan glai neu sment. Gelwir hyn yn ddull aml-rwystr.
Lucy Bailey is a chartered physicist working for Radioactive Waste Management, and it’s her job to show that a Geological Disposal Facility (GDF) will not cause any harm to people or the environment. Geological disposal involves isolating and containing radioactive waste in sealed vaults and tunnels deep underground, between 200 m and 1000 m below the surface. This prevents radioactivity from ever reaching the surface in levels that could cause harm.
Nucleargraduate Heather Patterson was impressed by the expertise of budding nuclear specialists who attended a recent event for PhD students in Manchester.
NDA Research Manager Yvonne Morris looks back on a conference that attracted more than 100 people to share ideas and progress on the latest research activities in nuclear decommissioning. The annual Nuclear Frontiers conference has taken place for the last …
NDA Head of Technology Melanie Brownridge is inspired by the promising innovative ideas now being explored in the £8.5 million competition to find new ways of dealing with problematic, highly radioactive nuclear facilities.
Mae Jonathan Turner yn rhannu ei brofiadau o ymweliad â rhai o gyfleusterau gwastraff ymbelydrol Sweden. Yn dilyn hyn mae sesiwn gyfweld fer gyda Kaj Ahlbom, daearegwr sydd wedi bod yn rhan o’r rhaglen dewis ac archwilio safleoedd yn Sweden am 25 o flynyddoedd.
Jonathan Turner shares his experiences from a visit to some of Sweden’s radioactive waste facilities. This is followed by a short interview session with Kaj Ahlbom, a geologist who has been involved for 25 years in the Swedish site selection and site investigation programme.
