Nuclear renaissance? US OKs new reactor design [View all]

Source: MSNBC

Opening the door to a new generation of nuclear reactors, federal regulators on Thursday approved a design that a nuclear watchdog group acknowledged is an improvement but still not ideal.

The AP1000 reactor, designed by Westinghouse Electric Co., is safer than the current generation of U.S. reactors, which date back 30 years or more, members of the Nuclear Regulatory Commission said in voting for approval.

"The design provides enhanced safety margins through use of simplified, inherent, passive, or other innovative safety and security functions, and also has been assessed to ensure it could withstand damage from an aircraft impact without significant release of radioactive materials," NRC Chairman Gregory Jaczko said in a statement.

Fears of an aircraft impact were heightened after the Sept. 11, 2001, attacks.

Apparently you don't either. FBaggins Dec 2011 #108
