KEWAUNEE, Wis. (AP) -

The Nuclear Regulatory Commission is proposing a $70,000 civil penalty against the owner of the Kewaunee nuclear power plant, which will soon be decommissioned.

The NRC says fire drills were not being properly conducted and that fire drill records were falsified. Regulators say their investigation concluded that between August 2009 and December 2011 a fire brigade trainer held training sessions instead of actual fire drills and then falsely claimed the drills were completed.

Regulators say Dominion Energy has taken corrective measures, including actions against the former trainer and the trainer's supervisor and a revision to the plant's fire drill procedures. Dominion did not immediately return a call for comment.

Dominion announced earlier that the Kewaunee plant will be shut down and decommissioned. The plant will stop operating May 7.
