Waste management
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.
