International Herald Tribune: The Nuclear Regulatory Commission announced tighter security requirements Tuesday for 33 research and test reactors, located mostly at universities, in response to a energy law passed by Congress in 2005.Under the new rules says the IHT, any person seeking unescorted access to a research or test reactor facility must be fingerprinted and undergo an FBI background check. In the past such checks were required only for reactor facility employees with access to sensitive security information.
