Sequoyah Unit 2 remains safely shutdown following an electrical issue in one of the four reactor coolant pumps.  The reactor shutdown as expected.   When the issue is fixed, the reactor will return to full power. 

SQN Unit 2 Key Points

  • TVA's Sequoyah Unit 2 reactor automatically shut down at approximately 7:26 p.m. on Thursday, August 16.   All equipment operated as designed and the unit remains safely shut down. 
  • The cause of the reactor shutdown was an electrical issue in one of the four reactor coolant pumps.    
  • Unit 2 has four reactor coolant pumps which circulate water through the reactor. 
  • When the issue is fixed, the reactor will return to full power.  
  • Sequoyah Unit 2 was operating at 100 percent power and had been online 421 days when the shutdown occurred.
  • While the unit is shutdown, non-radioactive steam may be vented to the atmosphere.  This is normal and may be heard by nearby residents.  We apologize for any inconvenience the noise may cause our neighbors.
  • Sequoyah Unit 1 is operating at 100 percent power.  The unit has been online 87 days.
    • TVA has a robust power system with a good mix of generating facilities including 29 hydroelectric dams, 11 coal-fired power plants, three nuclear plants and 11 natural gas-fired power facilities that can produce about 34,000 megawatts of electricity, delivered over 16,000 miles of high-voltage power lines.
