Outgoing Nuclear Regulatory Commission Chairman Gregory Jaczko will face his Republican critics next week during a House Energy and Commerce Committee hearing.

Jaczko will testify at the May 31 hearing alongside the other four commissioners, an NRC spokesman confirmed. The commissioners’ behind-the-scenes squabbling over policy and personality matters has tumbled into the spotlight in recent months.

The joint hearing of the committee’s environment and energy subcommittees will focus on Jaczko’s leadership at the commission as well as recent policy decisions, including the panel’s recent approval of the first new nuclear reactors in decades.
