Prosecutors said Saturday they will launch an all-out investigation into nuclear reactors suspected of using unauthorized parts amid concerns over power shortages.
Two power-generating atomic reactors were turned off earlier this week after they were found to be using substandard control cables supplied under fake quality warranties. The suspension sparked worries about a power shortage ahead of high demand in summer.
"Although the investigation started after the Korea Hydro & Nuclear Power Co. filed suits against a manufacturer and a testing agency of the control cable, we will look into all evidence related to fake nuclear parts," a senior official at the Busan District Prosecutors' Office said. "We will proceed with the investigation taking into account other potential irregularities."
The Korea Hydro & Nuclear Power is a state-funded nuclear agency based in the southeastern port city of Busan.
The latest move comes after officials at the presidential office on Friday said that it was not only the control cables that are problematic, but many other reactor parts are also believed to have similar problems.
These problems were uncovered when the Board of Audit and Inspection and other agencies conducted a joint investigation last year and the current government became aware of them while looking into the latest case, they said.
Prosecutors said they plan to establish a special team of investigators who have expertise in nuclear reactor issues as irregularities by some firms could be part of a massive corruption scheme.
The presidential official pledged to fully disclose the findings of the probe and draw up fundamental measures to ensure safety.
