An Era Ends at the Fort Calhoun Nuclear Power Plant

Shortly before 1 p.m. Monday, operators in the control room of the Fort Calhoun nuclear power plant pushed a red button, initiating an automatic shutdown of the reactor. So ended commercial operations for the nation’s smallest nuclear power plant, located along the Missouri River, about 20 miles north of Omaha, Neb.

fcsWhen it happened, just as it had done when the plant began operations 43 years earlier, the NRC had staff onsite to ensure events unfolded as planned, systems functioned as designed and public health and safety were protected.

“The shutdown was done in a very professional manner,” said Geoff Miller, a branch chief in the NRC’s Division of Reactor Projects, who oversees the plant from the NRC’s Region IV office in Arlington, Texas. By his side was Lindsay Brandt, a reactor inspector from the Region IV office, who also monitored the shutdown.

Max Schneider, the Senior Resident Inspector at Fort Calhoun, was in the plant monitoring the shutdown and checking to ensure that all plant systems responded as designed. “Everything went very well. There were no issues with plant equipment,” said Schneider, who reported to the site in June 2014 after serving as a Resident Inspector at the Pilgrim nuclear power plant in Massachusetts.

“I’ve watched lot of plant shutdowns prior to maintenance and refueling outages,” Miller said.  “Usually there is a lot of tension and excitement in the air in anticipation of events to follow but there was not a lot of that Monday. Things were subdued.”

The Omaha Public Power District’s Board of Directors voted several months ago to shut down Fort Calhoun for commercial reasons.

Brandt will remain at the plant for another three or four weeks and then return to the NRC’s Region IV, where she will resume other duties. Schneider will remain onsite for six months to a year to monitor post shutdown activities and ensure a safe transition from commercial operations to decommissioning mode.

Inspectors from the NRC’s Region IV office will conduct periodic inspections to ensure that spent fuel is being stored safely and securely in the plant’s water-filled spent fuel pool and in dry cask canisters while it remains onsite. The NRC will also conduct periodic inspections of decommissioning activities.

Within 30 days, Omaha Public Power District officials are expected to submit a letter to the NRC certifying the permanent cessation of commercial operations and stating that all of the radioactive fuel has been permanently removed from the reactor vessel. When this happens, OPPD will have surrendered its authority to operate the reactor or reload fuel in it. They have two years in which to file a report with the NRC, describing their plans for decommissioning the plant.

NRC Finishes Review of Vermont Yankee Decommissioning Planning Report

More of a marathon than a sprint, the decommissioning of a nuclear power plant can in some cases take decades. But central to the successful completion of that process is careful planning and vigilant oversight.

vyIn December of 2014, the Vermont Yankee nuclear power plant embarked on that phase of its life after being permanently shut down. As required by the NRC, Entergy, the plant’s owner, submitted a Post-Shutdown Decommissioning Activities Report, or PSDAR, on Dec. 19, 2014.

What exactly is a PSDAR? It is a report designed to provide the NRC and public with a general overview of the company’s proposed decommissioning activities. The report includes estimated costs for decommissioning and an affirmation that the decommissioning can be completed consistent with the site’s environmental statement.

Since the PSDAR only provides information and is not a federal action, it does not require NRC approval. However, the agency does review such submittals to confirm they meet regulatory requirements.

Besides performing an evaluation of the nuts-and-bolts aspects of the decommissioning plans, the NRC staff also reviewed public comments regarding the report. Along those lines, the agency held a public meeting on Feb. 19, 2015, in Brattleboro, Vt., for the purpose of receiving comments. Those remarks and others submitted separately in writing were all considered as the report was being prepared.

The NRC staff has now completed its review of the report and has determined the planned decommissioning activities, schedules and other information described in it are consistent with the agency’s requirements in this area. A copy of the NRC’s letter to Entergy regarding the PSDAR review results will be made available in the agency’s electronic documents system, ADAMS.

Also on the topic of Vermont Yankee’s decommissioning, as of Feb. 1, 2016, the responsibility for Vermont Yankee has been transferred within the NRC from the office responsible for operating reactors to the office responsible for decommissioning nuclear power plants.

Going forward, the Office of Nuclear Material Safety and Safeguards’ Division of Decommissioning, Uranium Recovery and Waste Programs will oversee licensing activities involving Vermont Yankee.

The NRC will continue to perform inspections at Vermont Yankee, with the intention of being on-site anytime a major activity is taking place.
