Subject:
Waterford 3 SES Docket No. 50-382 License No. NPF-38 Inservice Inspection (ISI) Reilef Request ISI-001, Revision 7, Limited Examination of Welds / Components Gentlemen:
In accordance with the Code of Federal Regulations 10CFR50.55a(g), Inservice Inspection Requirements", licensees must perform an Inservice Inspection of certain ASME Code Class 1,2, and 3 pressure-retaining components. The inspection
)
requirements for the first interval at Waterford 3 SES are contained in the ASME Boiler and Pressure Vessel Code,Section XI,1980 Edition with addenda through I
Winter 1981.Section XI stipulates % amount of examination required for each component.
N Whenever a complete examination, as defined by Section XI, is not attainable due to component design or configuration, the limitations to the required examinations must be submitted to the NRC per 10CRF50.55a(g)(5)(iii). In compliance with this regulation, Waterford 3 is submitting the attached relief request.
t Revision 7 of Relief Request 1S1-001 is enclosed for your review in Attachment 1.
Tables 1 and 2 of this attachment contain a complete listing of alllimited examinations performed during the first inservice inspection interval at Waterford 3, which ended July 1,1997. Table 2 contains a list of components for wliich relief was 9001290047 980127

Relief Request 1S1-001, Rev. 7 Component Classification Class 1 and 2, Examination Categories B-A, B-8, B F, B H, B-J, B L-2, C-A, C B, C-C, C F Examination Requirement For each code item requiring a surface and/or volumetric examination, the examination tables in the Waterfo ' '
st interval Inservice Inspection Program identify a figure which illustrates th 9mination requirement for a specific code item. These figures were derived from those shown in IWB-2500-1 through 20 and IWC-2500-1 through 13 of Section XI and have been enhanced to show exact weld configuration as it exists at Waterford 3.
Relief Requested Waterford 3 is requesting that relief be granted from obtaining 100% coverage when examining the items contained in Table 1.
Basis for Relief Class 1 and 2 piping and components are designed with welded joints such as nozzle-to-pipe, pipe to elbow and reducer-to-tee which physically obstruct all or part of the required examination. Every effort was made when selecting welds to minimize the number of welds requiring relief. Additionally, multiple angles, search units, extended Vee paths and other techniquas (i.e., Refracted L waves) were used to provide additional coverage where practical. To perform the Code-required examination, mo6fication and/or replacement of the component would be required. The examinations performed on the subject welds in addition to the examination of similar welds contained in the program would detect generic degradation, if it existed, therefore demonstrating an acceptable leve: of integrity.
Writerford 3 has generated a detailed summary of the ASME Code Class 1 and 2 piping and component welds / areas which received a limited or partial examination during Rns. The summary identifies the specific weld / area and the cause for the partial examination. The listing of welds / areas receiving a partial exam during RF8 is atached (Table 1) to this relief request.
