the aftermath of this typhoon, units 2 and 3 of the Wolseong nuclear power plant in Gyeongju have stopped.



During the last typhoon'Mysak', 4 nuclear power plants in Busan were automatically shut down, but reporter No. Gyu pointed out whether there is a problem with safety management.



<Reporter> It



is 8:38 am today (7th) when the turbine generator of Wolseong Nuclear Power Plant Unit 2 in Gyeongju, Gyeongsangbuk-do has stopped.



At 9:18 a.m. 40 minutes later, the turbine generator of Wolseong Nuclear Power Plant Unit 3 was also shut down.



Korea Hydro & Nuclear Power is estimated to have had an abnormality in the transmission facilities outside the power plant due to the influence of the typhoon high line.



The generator was automatically stopped because the power generated by the nuclear power plant could not be transmitted to the outside.



KHNP said that the power of the reactor that runs the generator has been reduced to 60% of the normal level to maintain a safe state and that there is no problem with the cooling system.



He explained that there were no radioactive leaks from turbine shutdown.



Both Wolsong Units 2 and 3 are 7 million MW-class pressurized heavy water reactors and began commercial operation in 1997 and 1998, respectively.



Earlier on the 4th, the nuclear power plants of Kori Units 3 and 4 and Shin-Kori Units 1 and 2 in Jangan-eup, Busan, were stopped.



It is presumed that power transmission was not possible due to a problem in the transmission system outside the power plant due to the influence of typhoon Mysack.



An emergency diesel generator was started due to incomplete external power supply to the reactor.



[Bumjin Jeong/Professor, Department of Nuclear Engineering, Kyunghee University: There are scenarios when these events happen.

Since electricity cannot be sent to the transmission and substation facilities, it can be considered that the reactor was shut down to keep the reactor safe.] The



Nuclear Safety Committee said it plans to determine when to resume operation after investigating the exact cause of the nuclear power plant shutdown.
