The U.S. Nuclear Regulatory Commission (NRC) began a series of inspections at the 500 MW Fort Calhoun nuclear power plant in Nebraska to examine the plant’s restart checklist and evaluate a recent cooling water pump issue.
Inspectors will look into the condition involving four main water pumps incorrectly anchored using shorter bolts than required. The pumps, referred to as raw water pumps, provide the main cooling water from the Missouri River to the plant.
Other inspectors are reviewing items from the restart checklist, including flooding, fire and an ongoing safety culture evaluation, totaling about 450 items that need to be looked at before any restart authorization decision can be made. NRC inspectors will write a report on their findings within 45 days of the end of the inspection.
