Dive Summary:

• The Nuclear Regulatory Commission says it has no idea how a pair of goldfish swimming in a pitcher of radioactive water got into an underground steam tunnel at FirstEnergy’s Perry nuclear plant in Perry, Ohio, regulators said Monday.
• "I can't speculate where the contaminated water could have come from," said NRC spokeswoman Viktoria Mitlyng. "There are locations in the plant that have slightly radioactive water. We are not aware of any type of leak from the primary coolant system."
• Despite the mysterious event, the NRC said the goldfish do not indicate a security or safety crisis. But an investigation continues to track the possibility that an employee smuggled the goldfish into the plant.
