Exelon's Clinton Power Station. 

CLINTON — The Clinton nuclear power plant will remain under increased oversight by the Nuclear Regulatory Commission following two recent incidents where investigators found a pair of low-to-moderate safety issues.

In a recent letter to the company, Steven West, a NRC regional administrator, notified Exelon the result of an inspection related to a degraded condition on a safety-related pump would be characterized as “white” and therefore, considered a low-to-moderate safety risk.

NRC inspectors determined the plant’s failure to previously identify the issue resulted in its failure. NRC inspectors verified that the pump has since been repaired.

The issue was documented during an inspection late last year. In a letter dated Feb. 2, officials at the plant did not contest the finding and indicated there were no plans to appeal.

“Clinton Power Station employees discovered the degraded condition, notified the NRC, and made the necessary repairs according to procedure,” said Exelon spokesman Gabe Goldsmith. “The station has numerous backup sources of power and at no time was there any risk to the safety of our plant, our workers or the public. We do not contest the technical violation and we welcome the NRC’s independent oversight.”

Clinton has been under increased NRC oversight since the third quarter of 2017 due to a previous safety issue. Earlier in the year, NRC inspectors discovered the plant failed to properly consider installing new electrical components on an emergency diesel generator room ventilation fan. A repair resulted in the diesel generator being inoperable for a period of time that exceeded requirements. NRC inspectors reviewed and approved the plant’s actions to resolve the issue.

Viktoria Mitlyng, a senior public affairs officer with the NRC in Lisle, said the Clinton plant will remain under increased oversight until NRC inspectors conduct reviews to verify that Exelon officials fully understood the causes for both findings and have taken sufficient action to prevent recurrence.
