Emergency Planning for Nuclear Power Plants

Nuclear Energy Activist Toolkit #47

The NRC’s regulations include requirements intended to prevent serious nuclear plant accidents from occurring and to mitigate one should it happen. Because these measures, even if fully and faithfully implemented, reduce rather than eliminate the chances of a serious accident, the NRC’s regulations also include requirements to protect the public from radioactivity released during an accident.

NRC’s Transparency: Glasnost or Half-Glasnost?

Nuclear Energy Activist Toolkit #46

The NRC’s words about openness:

The Vienna Conference on Nuclear Weapons

I recently returned from the Vienna Conference on the Humanitarian Impact of Nuclear Weapons (HINW14), the third such conference since March 2013 spearheaded by a number of international civil society organizations and non-nuclear weapons states. These states are growing increasingly impatient with the nuclear weapons states in their lack of progress toward global disarmament—as they pledged to do in Article VI of the 1968 Nuclear Non-Proliferation Treaty (NPT).  Read More
