Two contract workers admitted to placing carnival-type goldfish in an underground steam tunnel at the Perry nuclear power plant in Ohio, according to WKYC-TV.
FirstEnergy (NYSE: FE) officials discovered the goldfish swimming in a juice pitcher in the restricted tunnel in May. The U.S. Nuclear Regulatory Commission also looked into the incident since the fish were left in a secure area. The plant had been offline since March due to a planned outage and was returned to service in May.
The contract workers who admitted to placing the goldfish there reportedly said it was a practical joke, but that prank may have them blacklisted from working in any other U.S. nuclear power plant, the news station said. Four other workers admitted they knew about the prank but did not tell anyone, the report said.
