COVERT, MI -- Another issue was discovered during an inspection at Palisades nuclear plant that will require a repair, according to a Nuclear Regulatory Commission (NRC) document.

On Saturday, Nov. 10, with the plant in a refueling outage, during an NRC required bare metal visual inspection of the reactor head, a through-wall leak was identified on a reactor vessel head control rod drive nozzle, a NRC preliminary notification document dated Nov. 14 states.

There was no safety impact on the plant or the public and the leak was small enough that radioactive levels were not detected above normal within a containment area of the plant, NRC Spokeswoman Viktoria Mitlyng said.
