spokesman Dr Carl Clowes said the new station could be a target for terrorists and would see highly toxic waste kept on the site for 150 years.
Dylan Morgan from PAWB
said: "About 160,000 people were forced from their homes in the Fukushima area in order to escape from the radiation that would damage their health.

Now PAWB says it has identified the potential to bring between 2,500 and 3,000 jobs to the island, although most of them are already in existing energy Carl of proposals.
PAWB say solar and biomass could also provide 750 jobs with projects on the table in Holyhead and Llangefni, and 150 jobs could come from wave and tidal schemes.
Neither PAWB, the Wales Anti-Nuclear Alliance nor anti-nuclear campaigner Dr Max Wallis received invitations to the meeting.
This includes ensuring that organisations such as PAWB get every opportunity to ask appropriate questions regarding waste and costs and so on.
Dylan Morgan, coordinator for PAWB
, challenges public bodies to say how they would cope with a serious accident at Wylfa, and evacuate much of North West Wales.
