In the fall of 2012, Greenpeace requested an analysis from the Radiation Authority. This agency's tests are used to assess the risk of a meltdown. However, that analysis is now classified as confidential. Previously, this kind of information was public.
Ulf Yngvesson, general counsel at the Radiation Safety Authority says they could not give out the report because it held too many technical details that could get into the wrong hands.
Greenpeace says they do not need those kinds of details, but think that the authority is covering up something. But Yngvesson at the Radiation Safety Authority says if there had been a risk of radioactivity or meltdown, they would shut down the reactor.
