An internal inquiry has concluded that the head of the Nuclear Regulatory Commission strategically withheld and controlled information to steer decisions on a massive dump for radioactive waste his way.
The seven-month long investigation by the agency's inspector general says NRC Chairman Gregory Jaczko was "not forthcoming" to other commissioners when he shut down a scientific review of the Energy Department's application to build the underground dump at Yucca Mountain, Nev.
In an unusual move, Jaczko sought to pre-empt the report in a statement Wednesday. He says the investigation reaffirmed that his actions have been legal and consistent with his authority as chairman. But he acknowledges to the IG that he at times lost his temper and used "forceful" management techniques.
House Republicans requested the IG report.
