Kock

Andrea Kock was named director of the Nuclear Regulatory Commission’s Office of Nuclear Materials Safety and Safeguards.

Kock was previously the Region I administrator in King of Prussia, Pa., and had been serving recently as temporary head of the NMSS.

NMSS licenses and regulates the facilities and materials associated with the processing, transport, and handling of nuclear materials, including uranium recovery activities and the fuel used in commercial nuclear reactors. The office also implements the NRC’s Agreement State program; liaises with American Indian tribal governments; and supports agency rulemaking, environmental review, and financial assurance projects.

Background: Kock first joined NRC in 1996 as a radiation specialist in Region II, eventually working up to supervisor positions in the former Office of Federal, State, Materials and Environmental Management Programs, the Office of Nuclear Reactor Regulation, and the Office of Nuclear Reactor Regulation, where she was deputy office director for engineering.

Prior to her career at the NRC, Kock was a Department of Energy health physics fellow. She is a graduate of the NRC’s Leadership Potential Program and the Senior Executive Service Candidate Development Program.
