Request #9, NRC SIT Question#3 Information
- 3.
Was there any analysis of why re-tensioning was required in past tendon surveillance activities (done at that time of surveillance testing)?
Response: There was no analysis performed during past surveillance testing years in which tendons were re-tensioned.
Additional information in response to the above question: See License Request No. 24 - NRC SIT Question# 18 folder, under sub-folder: "IWL - Tendon Surveillance History" for information, discussions and actions taken related to tendon lift-off testing and re-tensioning. Below shows the breakdown of the information contained in that folder and highlights specific areas related to the tendon lift-off testing and re-tensioning.
