.............A complete non-event really; you would probably get a bigger radiation dose flying across the pond or from a chest x-ray. To make the story better a totally meaningless quote from our favourite nuclear "expert" - wonderful.
Possibly another attempt to stoke up anti nuclear feelings and fears. Remember that some hard decisions are needed soon (like years ago!) on building new power stations to fill that approaching hole in our generating capability. There are also those who'd like to do away with nuclear submarines.
