Palisades Nuclear Power Plant Returned to Service

March 16, 2014

Covert, Mich. – Palisades Nuclear Power Plant was returned to service at 6:44 a.m. today following completion a 55 day, 19 hour planned refueling and maintenance outage.

During the outage, 64 used fuel assemblies were removed from the reactor vessel and replaced. In addition, more than 8,500 work activities were completed. Some of the major projects completed include inspections of the reactor vessel and Palisades’ two low pressure turbines.

Early in our refueling outage planned inspections were conducted of all 45 control rod drive housings at Palisades. Control rod drives permit control rods to be inserted and withdrawn from the reactor core. Each control rod is encased inside one housing. Seventeen of the 45 housings did not meet Palisades’ inspection criteria and we determined that those housings would require replacement prior to returning Palisades to service. There was no leakage associated with any of the housings and there was no risk to the health and safety of the public or employees.

As a proactive measure to ensure continued safety and reliability of our facility, we replaced all 45 of our control rod drive housings with new housings of a different design and material. One housing was replaced in 2012, with the remaining 44 replaced during this outage.

The safety of Palisades is our highest priority. Replacing all of the housings – including those that met inspection criteria – represents our continued commitment to achieve the highest levels of safety and reliability.

More than 1,000 outside workers assisted Palisades employees with outage work. The influx of more than 1,000 outside workers and their associated spending provided economic boost to the local communities.
