Consolidated Nuclear Security (CNS) agreed to pay $18.4 million to settle alleged False Claims Act violations regarding the submission of timecards for unworked hours to the National Nuclear Security Administration (NNSA).

CNS, which is contracted by the NNSA to manage its Pantex Plant in Texas, self-disclosed the apparent misconduct, the Department of Justice (DOJ) announced in a press release Tuesday. CNS will pay nearly $16.6 million in restitution, according to its settlement agreement.
