Question:
What is Yankee's inspection program for the Exxon Nuclear Company fuel at the next refueling?
Response
Yankee will conduct a post-irradiation examination of at least 5 of the 40 Core XII Exxon reload assemblies during the next two refueling In the event that any of these 40 assemblies are irradiated for outages.
a third cycle, or other Exxon fuel assemblies are exposed to significantly higher 1cvels than attained by the initial reload, examinations will also be performed during subsequent outages to insure the satisfactory operation of the Exxon fuel through the highest exposure levels expected.
Specific components to be examined include the top and bottom nozzles, the guide bars, the spacers and fuel tubes. The inspection of these components will include visual observations of weld integrity, inspection for distortion and abrasion, observation for bow, crud and discoloration, and other general characteristics to determine the effects of reactor operation. The results of these inspections will be evaluated and, if deemed appropriate, integrated into the design efforts for future reloads; any abnormalities observed will be reported to the NRC within 10 days.
The final results of the inspections will be provided to the NRC within 90 days of the completion of the efforts.
