(Bloomberg) -- Entergy Corp. agreedto review fire safety measures at all its nuclear reactors after aninvestigation by federal regulators found that workers at one plantfailed to follow rules and falsified records.

Contract workers at Entergy’s Waterford 3 nuclear power plant inLouisiana falsified reports showing they had performed fireinspections that never occurred between July 2013 and April 2014,according to a statement issued Friday by the U.S. Nuclear Regulatory Commission. An Entergysupervisor also failed to take action when provided withinformation of suspected wrongdoing, the agency said. Plantoperators are required to carry out periodic inspections to ensurefire doesn’t damage the reactor’s equipment.

Renewed scrutiny over safety

The commission’s findings come as Entergy faces renewed scrutinyover its safety record. Last month, nuclear regulators said thatthree of the company’s reactors will be subject to increasedfederal oversight because of safety shortcomings. And Entergy saidit was extending a maintenance outage at the Indian Point plantnorth of New York City after discovering bolts missing in areactor.

In light of the latest findings, Entergy agreed to complete acomprehensive review of its fire watch programs and improvetraining among other measures, according to the commission.

Entergy has stepped up its fire safety measures and thecontractors involved in the incident are no longer employed at thecompany, Leanna Weaver, a spokeswoman for Entergy, said in ane-mailed statement. "Entergy does not tolerate improper reportingor disregard of our protocols," Weaver said.
