Mae Llywodraeth Cymru wedi buddsoddi hefyd mewn gallu ymchwil ac arloesi niwclear yng Ngogledd Cymru, yn fwyaf amlwg drwy raglen Sêr Cymru, megis y Ganolfan Hydrolig Thermol Genedlaethol a chreu grŵp ymchwil y Sefydliad Dyfodol Niwclear.
The Welsh Government has also made investments in nuclear research and innovation capability in North Wales, most notably through the Sêr Cymru programme, such as the National Thermal Hydraulic Facility and the creation of the Nuclear Futures Institute research group.
