The Department of Energy’s Office of Environmental Management, which is responsible for the cleanup of 15 nuclear sites across the country, lacks a clear understanding of its costs for work not directly related to site cleanup, hampering the department’s ability to prioritize competing funding needs, according to a report by the Government Accountability Office.

A former senior resident inspector for the Nuclear Regulatory Commission pleaded guilty on December 13 in the U.S. District Court for the Western District of Virginia to making false statements on NRC inspection reports. Such false statements violate federal statutes and carry a maximum penalty of five years in prison.
