SKorea idles 2 nuke plants after cable tests faked

Source: Associated Press

SEOUL, South Korea (AP) — South Korea has idled two nuclear power plants after finding that test results for crucial control cables were falsified in a new blow to an industry mired in a graft scandal and safety lapses.

... The cables control valves that are responsible for cooling nuclear fuel or preventing the release of radioactive materials during an emergency. Another four nuclear reactors that were either shut down for scheduled maintenance or under construction were also using cables that had failed the tests.

... It said the cables, which were in use since December 2011, failed nine of 12 tests pertinent to their operation in a "loss of coolant accident."

... Last year, the South Korean nuclear industry was rocked by revelations that thousands of components used in nuclear plants had falsified quality certificates. Dozens of employees at state owned nuclear power plant operator, Korea Hydro & Nuclear Power Co., were prosecuted for taking bribes from contractors to accept substandard parts and machinery.

The last paragraph -- that THOUSANDS of components used in nuclear plants had falsified quality certificates is especially scary. And DOZENS of employees at state owned nuclear power plant operator, Korea Hydro & Nuclear Power Co., were prosecuted for taking bribes

1. And now it will take that much more money to get it right

4. The bad thing about this is South Korea does rely quite a bit on nuclear power

much like Japan has (or had until the disaster a few years ago). It maybe luck that greater scrutiny has been put on the plants here before something very bad happened. I tend to think if such a large scale disaster had not happened, we may have never known the deficiencies at the plants in Korea until it was too late. Korea is going to have to phase out nuclear power as some of the plants are pretty old.

5. Yup, "unprecedented power shortages" expected this summer

From the article: With the shut down of the 2 affected plants, a total of 10 nuclear plants are now offline. "Unprecedented power shortages are expected" (this summer). Korea has 23 nuclear power plants supplying about 30% of its energy {{probably meaning 30% of its electrical energy -Progree}}

=========================================
Not good at all. And although geographically a peninsula, which is bad enough, electrically S. Korea is an island all on its own because I doubt that they have much or any electrical ties with their only land neighbor -- North Korea (would be very surprised if they had any).

6. High electricity bills this summer

My wife is already getting on me about using the AC because our bills will be higher. Most of the energy (aside from nuclear power and some from wind farms off of Incheon) are imported from other countries including the United States.

8. Yup, I was thinking all their electricity is domestically produced but all the fuel needed to

power their electrical generating plants comes from overseas. (As well as fuel for all other purposes such as transportation, factories, home heating,....)

My understanding (since I don't think they have any electrical ties to N.Korea) is that the S. Korean electrical system is entirely on its own -- it must generate enough electricity to meet the load every moment in real time -- or shed some load (or partially collapse until supply and demand are matched). (I worked at an electric utility). A very precarious situation compared to geographically larger power networks like on the continents where electric utilities have mutual-support electrical ties with their neighbors.

But the fuel needed to power those generators as you indicate, is all imported. (excepting the windfarms which don't need fuel. And the nuclear fuel?)

At least that's my picture / understanding of it

Kind of the worst of both worlds -- needing to import all your fuel (including nuclear fuel? I suspect) -- while having no mutually aiding electrical ties with anyone.

Good luck!

7. And this year's summer English camps are gonna suck

Last year our camp had 2 2-hour blocks of no A/C during the day. I decided to bring some fans in from home to help with circulation. The rains eventually came in, but that first week sucked ass. --- everybody felt like this.
