Nuclear Regulation: Slow Progress in Identifying and Cleaning Up NRC's Licensees' Contaminated Sites

Pursuant to a congressional request, GAO reviewed the effectiveness of the Nuclear Regulatory Commission's (NRC) decommissioning program, focusing on: (1) NRC progress in identifying all former licensees' sites that require additional cleanup; (2) NRC progress in ensuring that sites on its Site Decommissioning Management Plan (SDMP) are cleaned up in a timely manner; and (3) factors that impede the timely cleanup of sites.
