[7] Unit 1 suffered a station blackout on 18 March 2001 when grid instability caused a loss of offsite power and both of the emergency diesel generator trains failed to start.
Both units had tripped off-line the prior day due to instability in the 345 kV offsite power transmission line, caused by salt-bearing seasonal sea smog.
[8] During the normal full operation of the power plant on 29 January 2005, Unit 2 reactor scram was initiated followed by a main turbine trip.
A universal logic card in the plant's solid-state protection system malfunctioned, erroneously reporting a low-low water level condition in the steam generators.
[11] While operating at reduced power in anticipation of typhoon Talim, on 1 September 2005, the Unit 2 main transformer differential protective relay tripped because a damaged support insulator caused one phase to flash to ground.
[12] Following the subsequent repair work, on 8 September 2005, as the unit was in a hot standby condition, a water hammer occurred in one of the main steam lines.
[16][17] The Unit 3 of the power plant was shut down on 16 November 2010 to undergo the EOC-19 outage after running in full cycle continuously, safely and stably for 539 days.
[19] One reactor of the plant was shut down to undergo an overhaul from 9 November 2015 to 7 December 2015 to replace fuel rods and maintain electrical equipment.
[22] On 23 July 2017, the second nuclear reactor coolant system of the plant failed and electricity generation was interrupted at 1:10 a.m.[23] The damage was resolved the next day.
