INTRO: Sea salps -- gelantinous, marine organisms that look like jellyfish -- may be small, typically measuring less than 10 centimeters tall. But the tiny creatures are turning out to be a major pest to South Korea’s nuclear industry.
The organisms have clogged water systems used to cool Korea Hydro & Nuclear Power Co.’s Hanul No. 1 and No. 2 reactors, forcing them to shut Tuesday, the second time in less than three weeks the units were taken offline due to sea salps. The reactors, which each have a capacity of 950-megawatts, were offline for about a week in late March.
The shutdowns could get costly the longer they continue. If the amount of lost power from the initial eight-day disruption was offset with generation from liquefied natural gas, it would require a 60,000-ton cargo of the supercooled fuel, costing roughly $21.8 million, according to BloombergNEF analyst Olympe Mattei.
Sea salps can link up into chains several meters in length and have been said to resemble a crystal chandelier drifting through the ocean.. (MORE)
