Safety at nuclear plants

The Nuclear Regulatory Commission approved new security rules for nuclear power plants, including measures to better protect against cyber attacks. The rules also call for new training and qualification requirements for security officials and say operators must develop new ways to respond in case part of a plant is lost in an explosion or fire. Many details remain classified for security reasons.

Watchdog groups criticize the NRC for not going far enough. In particular, they say nuclear plants should be required to protect against aircraft attacks and to repel ground-based terrorists.
