Subject:
Waterford 3 SES Docket No. 50-382 License No. NPF-38 Inservice inspection (ISI) Relief Request 1S1-017, Revision 1, Request Authorization to Substitute Visual (VT-3) Examination for the Code-required Surface or Volumetric Examination of the four Reactor Pressure Vessel Support integral Attachment Welds (ISI Exam Number 01-074)
Gentlemen:
l On February 21,1997, during a conference call between NRR, INEL and Waterford 3 personnel, questions were raised regarding the alternative examination proposed j
in Inservice Inspection Relief Request 1S1-017, revision 1. In letter W3F1-97-0014 dated February 13,1997, Waterford 3 requested authorization to perform a visual (VT-3) examination in lieu of the Code-required surface or volumetric examination of the Reactor Pressure Vessel Support Integral Attachment Welds.
During the call, INEL raised questions about using a VT-3 examination in lieu of a surface or volumetric examination. The ensuing discussion addressed the type of loading the Reactor Pressure Vessel Support Integral Attachment Welds would be subjected to, the type degradation that could occur and the method of examination that would best detect this degradation.
The feasibility of performing a VT-1 examination of the welds was also addressed.
The anticipated dose rates and inaccessibility to portions of the weld were discussed at length. Recognizing that only a partial examination would be feasible, INEL and h
NRR recommended a partial VT-1 in conjunction with the requested VT-3 be
,N.f tl '
I considered in lieu of the Code-required surface or volumetric examination.
