| Event Description | The following information was provided by the licensee via fax:
On March 14, 2023, at 2000 EDT, in accordance with 10 CRFR 50.72(b)(3)(xiii). Yankee Nuclear Power Station Independent Spent Fuel Storage Installation (ISFSI) determined that the impacts of a severe winter storm have resulted in a major loss in off site response capability. Since approximately 0200, very heavy snow has fallen and greater than two feet has accumulated on site. All security related equipment has remained functional, and there have been no impacts to methods of offsite communications or emergency assessment capability. The concrete cask heat removal systems have remained operable in accordance with the NAC International multi-purpose container system (NAC-MPC) technical specifications. From approximately 0550 until 1840, offsite power was lost, and the site was powered by the security diesel generator. Periodically throughout the day, the Security Shift Supervisor was in contact with State and local police to ensure response capability. At the 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> update, the law enforcement agencies reported that there were recent reports of trees and power lines being downed by the weight of the snowfall causing road closures and significantly impacting routes and response times to the site. The site remains fully staffed.
On March 14, 2023, at 2000 EDT, in accordance with 10 CFR 50.72(b)(3)(xiii), Yankee Nuclear Power Station Independent Spent Fuel Storage Installation determined that the impacts of a severe winter storm resulted in a major loss in offsite response capability. Downed trees and power lines in conjunction with up to thirty-six (36) inches of snow prevented vehicle passage on normal response routes. On March 15, 2023, at approximately 1700 EDT, these roadways were passable, and employees and emergency vehicles regained normal access to the site. However, the Town of Rowe, Massachusetts police chief informed the site that the town remained in an emergency status and the roadways may need to be intermittently closed in order for utility workers to restore power lines and continue to clear tree limbs. On March 16, 2023, 1815 EDT, the Town of Rowe, Massachusetts police chief secured from the emergency. Therefore, this update is to inform the NRC that the Yankee Nuclear Power Station Independent Spent Fuel Storage Installation has similarly returned to baseline operations. NRC Region I management has been updated throughout the progression of the storm and recovery. A press release is not anticipated. Notified R1DO (Bickett) |
