Guidance: Gwaredu daearegol

Mae technoleg niwclear wedi bod yn rhan o’n bywydau am dros 60 o flynyddoedd, ac mae’n cael ei ddefnyddio i gynhyrchu pŵer, ym maes diwydiant, meddygaeth ac amddiffyn. Erbyn heddiw, mae ynni niwclear yn darparu bron i un rhan o bump o holl drydan y DU. Mae’r gweithgareddau yma wedi creu gwastraff ymbelydrol y mae angen i ni ei reoli yn ddiogel.
Mewn Cyfleuster Gwaredu Daearegol (GDF) bydd y gwastraff yn cael ei roi gannoedd o fetrau o dan y ddaear. Cydnabyddir yn rhyngwladol mai GDF yw’r datrysiad hirdymor mwyaf diogel; bydd cael un yn y DU yn creu swyddi a buddsoddiad gwarantedig i’r gymuned dan sylw.

Detailed guide: The UK’s nuclear history

Our nuclear legacy

The United Kingdom is a pioneer of nuclear technologies and opened the world’s first commercial nuclear power station in 1956, at Calder Hall near Sellafield in Cumbria. Nuclear power has delivered great benefits: it has supported national defence, generated electricity for more than 60 years and our country remains a world-leading nuclear enterprise.

Today the UK is faced with the challenge of cleaning up the legacy of its early nuclear operations – a large-scale programme undertaken by the Nuclear Decommissioning Authority (NDA). This includes delivering innovative solutions for managing radioactive waste that meet today’s safety standards and will protect us into the distant future.

Why we use nuclear energy today

UK Government policy is to have a wide mix of energy supplies, so we use nuclear alongside other energy sources, such as gas and solar. Today, nuclear energy generates around one fifth of the country’s electricity, and under current government proposals that include Hinkley Point C, some of our power will come from nuclear sources in the future.

There are important reasons why nuclear is part of the mix:

  • it’s a low carbon choice that supports the UK’s climate change goals: nuclear power stations generate electricity without emitting greenhouse gases like carbon dioxide and methane

  • nuclear power plants produce electricity 24 hours a day, whatever the weather

  • nuclear power plants don’t require a daily supply of new fuel to operate, unlike gas, coal and biomass plants

Where else does radioactive waste come from?

Besides nuclear power generation, radioactive waste comes from:

  • Medical – in particular, radioactive materials are used to sterilise equipment, and help diagnose and treat medical illnesses.

  • Industry – for example, gamma rays are used to test the quality of welds or the thickness of products, such as paper.

  • Defence – includes the operation of active nuclear-powered submarines and the decommissioning of retired submarines.

  • Research and development – from nuclear fusion technology to developing new radiotherapy treatments to testing novel solid materials for encapsulating liquid radioactive wastes.

The full list of radioactive waste present in our country is kept up to date and published on the UK’s Radioactive Waste Inventory website.

What we need to do now

The radioactive waste resulting from power generation, medicine, defence and other industries needs to be managed carefully. Existing waste is currently stored above ground at more than 30 sites around the UK. These surface stores can be safe for many decades, but require continuous protection to keep them secure and in good condition, as the waste remains radioactive for hundreds of thousands of years.

There is international consensus that geological disposal is the safest and most secure way to manage higher activity waste for the long term, and that a Geological Disposal Facility (GDF) will ensure that the responsibility of continually protecting this waste is not passed on to future generations.

Detailed guide: Radioactive Waste Management (RWM) – about us

Radioactive Waste Management (RWM) is a public organisation established by government and responsible for planning and delivering geological disposal in the UK.

We collaborate with scientists around the world on multi-million pound research programmes, sharing the latest scientific advances and best practice. We also work with the producers of radioactive waste to find ways to package it that are suitable for disposal in a Geological Disposal Facility (GDF).

Our vision is to create a safer future by managing radioactive waste effectively, to protect people and the environment.

30 years of scientific research and development

The RWM team includes scientists and engineers with over 30 years’ experience in carrying out research and development to support geological disposal, supported by community engagement specialists.

Our organisation is a subsidiary of the Nuclear Decommissioning Authority (NDA), a public sector organisation tasked by the UK government with the safe and efficient clean-up of Britain’s civil nuclear legacy.

Independent scrutiny

Our work is regulated by the Office for Nuclear Regulation (ONR) and the following agencies:

It is also scrutinised by an independent body set up by the government, the Committee on Radioactive Waste Management, (CoRWM).
