SC Nuclear Plant Gets Yellow Warning Over Another Cracked Emergency Fuel Pipe

Federal regulators have issued a preliminary "yellow" warning to Dominion Energy after cracks were discovered again in a backup emergency fuel line at their South Carolina nuclear plant. ABC News reports: 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. 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.
