| ENS 56410 | 14 March 2023 22:50:00 | Yankee Rowe | NRC Region 1 | 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 hours 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) | |
| ENS 40826 | 17 June 2004 15:53:00 | Yankee Rowe | NRC Region 1 | Westinghouse PWR 4-Loop | Three 55 gallon drums of sand, each impregnated with 1.73 microCuries Cs-137, were shipped to Yankee Rowe from Atlanta, Georgia via Federal Express. The specific activity of the material is 32 picoCuries per gram. Upon arrival at Yankee Rowe, a hole in one of the drums was noticed and about 70 pounds of sand was determined to be missing. About 3 pounds of material was recovered from the shipping truck. The hole appeared to be caused by a fork lift puncture. The specific activity of the material is less than the Department of Transportation reportable quantity. Yankee Rowe contacted state of Vermont and notified the NRC Resident Inspector. |
| ENS 40673 | 14 April 2004 13:00:00 | Yankee Rowe | NRC Region 1 | Westinghouse PWR 4-Loop | While dismantling the vapor containment using a torch, slag fell down on some plastic below and started a fire. The fire was reported to the control room at 1155. The licensee declared an unusual event at 1225. The fire department responded. The fire was extinguished at 1303. This is a decommissioned facility and there is no fuel in the reactor. No one was injured. There was only very low levels of radioactivity in the building of less than 1000 disintegrations per minute per 100 centimeters squared.
At 1408, Yankee Rowe terminated from the Unusual Event. Initial sampling indicates that there was no radiological release. Notified R1(McDermott), NRR (Reis), NMSS (Holahan), DIRO (Wessman), DHS (MacKee), and FEMA (Sullivan). |
| ENS 40562 | 2 March 2004 15:55:00 | Yankee Rowe | NRC Region 1 | Westinghouse PWR 4-Loop | A container of concrete rubble was being transported from the Plant to Palmer, MA where it would eventually be transported via railroad to a waste repository. The intermodal container connection to the trailer broke off allowing the container to fall off spilling contents on the road. The location of the incident is approximately two miles from the Plant at Ford Hill Road, in Rowe, MA. The net weight of the container is 38,860 lbs and it contains low level radioactive concrete. Site Radiation Protection was sent by the licensee to the location of the incident. The spilled concrete rubble will be placed in a new container which will be taken back to the site. Clean up of the area is in progress, and area release is pending a post clean up survey. No one was injured during this incident. The licensee has notified the NRC Resident Inspector, the local Fire Department, State and Local government agencies and the Environmental Protection Agency (EPA). A Press Release is being planned to be issued by the licensee. |
