SC nuclear plant issued a warning over another cracked emergency fuel pipe, latest in series of issues
The South Carolina nuclear plant has had 6 reports of small pipe cracks in the past 2 decades
{{#rendered}} {{/rendered}}- U.S. officials have issued a warning to a South Carolina nuclear plant over a cracked pipeline essential for cooling a reactor if electricity fails.
- The V.C. Summer plant near Columbia has had a series of reports in the past two decades over small cracks that were found on its fuel pipes.
- Dominion Energy, the owner of the nuclear plant, said its planning to improve the reliability of its backup system.
Federal officials have issued a warning about a substantial safety violation at a South Carolina nuclear plant after cracks were discovered again in a backup emergency fuel line.
Small cracks have been found a half-dozen times in the past 20 years in pipes that carry fuel to emergency generators that provide cooling water for a reactor if electricity fails at the V.C. Summer plant near Columbia, according to the U.S. Nuclear Regulatory Commission.
The agency issued what it calls a preliminary "yellow" warning to plant owner Dominion Energy last week.

It is the second most serious category and only seven similar warnings have been issued across the country since 2009, nuclear power expert David Lochbaum told The State newspaper after reviewing records from federal regulators.
A crack first appeared on a diesel fuel pipe in 2003, and similar pipes have had other cracks since then.

The agency issued the preliminary yellow warning because of the repeated problems.
The commission’s ruling is not final and Dominion will have a chance to explain what happened, utility spokesperson Darryl Huger wrote in an email

"With a commitment to continued safe operations, we are inspecting and maintaining our generator and related components. We will continue to keep the NRC updated on our future strategy to further enhance our diesel generators," Huger wrote.

The South Carolina company had plans to build two more reactors, but billions of dollars of cost overruns forced it to abandon the project in 2017 and sell to Dominion.

Dominion has recently requested to renew the license for the nuclear plant for an additional 40 years.
{{#rendered}} {{/rendered}}Longtime nuclear safety advocate Tom Clements told the newspaper the pipe problems should mean a lot more scrutiny by regulators.
"This incident serves as a wake-up call to fully analyze all such systems prior to a license-renewal determination,’’ Clements said in an email.
