Korea Hydro & Nuclear Power's Hanul Nuclear Power Headquarters (headed by Lee Seyong) announced that at approximately 6:11 p.m. on November 23, the turbine of Shinhanul Unit 1 (with a capacity of 1.4 million kW) was automatically shut down.


On November 21, after connecting to the grid and increasing output, the turbine generator of Shinhanul Unit 1 was automatically shut down due to a failure in the main generator exciter.


An exciter is a device that supplies field current to the main generator.



Currently, the reactor is being stably maintained at around 50% power. The cause of the exciter failure is under investigation, and follow-up measures will be taken after a detailed cause is identified.
