Wylfa on Anglesey chosen for UK’s first Small Modular Reactor, advancing the Clean Energy Superpower plan.

Mae Great British Energy - Nuclear (GBE-N) yn falch o gyhoeddi bod Wylfa yn Ynys Môn wedi cael ei ddewis fel y safle ar gyfer Adweithyddion Modiwlaidd Bach cyntaf y DU. Dyma garreg filltir bwysig yng nghynllun Clean Energy Superpower y llywodraeth.

Bydd y prosiect seilwaith strategol hwn yn darparu hyd at 1.5GW o ynni carbon isel i’r grid, gan gefnogi nodau sero net y DU a gwella diogelwch ynni. Bydd y datblygiad yn creu manteision economaidd sylweddol i Gymru hefyd, gan gynnwys creu hyd at 3,000 o swyddi yn ystod cyfnod prysuraf y gwaith adeiladu a chyfleoedd gyrfa hirdymor.

Ychwanegodd Simon Bowen, Cadeirydd GBE-N:

Dyma foment hanesyddol i’r Deyrnas Unedig a cham pwysig arall at wireddu potensial Prydain i arwain y ffordd o ran ynni niwclear.

Bydd yr Adweithyddion Modiwlaidd Bach cyntaf hyn yn Wylfa yn gosod y sylfeini ar gyfer dull seiliedig ar fflydoedd o ddatblygu niwclear, gan gryfhau annibyniaeth ynni’r DU a denu buddsoddiad hirdymor i’r economi leol.

Mae gan Wylfa hanes balch o ragoriaeth niwclear ac rydyn ni’n edrych ymlaen at adeiladu ar y sylfaen honno i ddarparu swyddi, hyfforddiant ac ynni carbon isel am genedlaethau.

Heddiw, mae Simon Bowen wedi cael ei gadarnhau fel Cadeirydd parhaol GBE-N.

Mae’r rhaglen adweithyddion modiwlaidd bach wedi cael £2.5 biliwn o gyllid gan y llywodraeth ac mae wedi’i chynllunio i ddenu buddsoddiad preifat, cryfhau cadwyn gyflenwi’r DU, a lleihau’r ddibyniaeth ar ynni wedi’i mewnforio.

Bydd GBE-N yn parhau i weithio gyda rhanddeiliaid a chymunedau lleol i sicrhau bod y prosiect yn creu gwerth parhaol, ac yn cynnal ymddiriedaeth y cyhoedd.

Great British Energy - Nuclear (GBE-N) is pleased to announce that Wylfa on Anglesey has been selected as the site for the UK’s first Small Modular Reactor (SMR), marking a major milestone in the government’s Clean Energy Superpower plan.

This strategic infrastructure project will deliver up to 1.5GW of low-carbon energy to the grid, supporting the UK’s net zero goals and enhancing energy security. The development will also bring significant economic benefits to Wales, including up to 3,000 jobs during peak construction and long-term career opportunities.

Simon Bowen, Chair of GBE-N, added:

This is a historic moment for the UK, and is another momentous step in realising Britain’s potential in leading the way on nuclear energy.

These first SMRs at Wylfa will lay the groundwork for a fleet-based approach to nuclear development, strengthening the UK’s energy independence and bringing long-term investment to the local economy.

Wylfa has a proud history of nuclear excellence, and we’re excited to build on that foundation to deliver jobs, training, and low-carbon energy for generations to come.

Today, Simon Bowen has also been announced as the Chair of GBE-N.

The SMR programme is backed by £2.5 billion in government funding and is designed to attract private investment, strengthen the UK supply chain, and reduce reliance on imported energy.

GBE-N will continue to engage with local communities and stakeholders to ensure the project delivers lasting value and maintains public trust.
