In answering an urgent question from Plaid AM Rhodri Glyn Thomas, First Minister Carwyn Jones said his cabinet are united in attempting to bring the UK's nuclear fleet to Milford Haven, arguing the move could bring jobs to Wales.
Conservative Paul Davies welcomed the plan and asked if the Welsh Government intends to explore the full economic impact of the bid.
But Plaid AMs condemned the Government, citing safety concerns.
The idea was first mentioned by Carwyn Jones at yesterday's First Minister's questions.
