1.0 STATEMENT OF \PPLICABILITY i This program outlines details for performing the preservice nondestructive examinations of the Sequoyah Nuclear Plant ASME Code Class 1, 2, and 3 com-r ponents (and their supports). The program has been organized to fulfill preservice examination requirements of the Sequoyah Operational Quality Assurance Manual, Part II, Sectica 5.1 and comply as practical with the regtJrements of Section XI of the ASME Boiler and Pressure Vessel Code. In accordance with 10 CFR Part 50, 50.55a(g)(1), a preservice inspection I
" - is not required for Sequoyah. However, the areas outlined in this program to receive a preservice inspection will be examined. The requirements of F ASME Section XI are in effect when the requirements of the applicable con-struction code have been satisfied.
m Specifics concerning performance of nondestructive examinations are not a part of this program, but are included in nondestructive examination
"* procedures (DPM N80E3 and SNP TI-51).
2.0 PURPOSE The Preservice Inspection Program (hereinafter PSI) is preliminary in nature and is employed to obtain detailed information for' inclusion in the Inservice Inspection Program. The examinations required by this program will establish acceptance of components for service. In addition, this program partially satisfies the preservice requirements of SR 4.0.5, f 4.4.5, and 4.4.10. The PSI Program serves as a means of determining built-in limitations caused by original plant design, geometry, materials of construction of the components, and the current *mchnology or state-of-art of nondestructive , testing. The PSI Program will also permit verification of the examination methods selected, finalization of detailed procedures, and will establish preservice examination dats to be used as a reference for later inservice examinations. f . 3.0 CODES OF RECORD This program was prepared to meet the requirement's of the 1974 Edition, Summer 1975 Addenda of Section XI of ASME Boiler and Pressure Vessel Code. ! n. Criteria for determining Class 2 pressure retaining bolting subject to examination is in accordance with the 1977 Edition, Summer 1978 Addenda of Section XI. Criteria for determining components subject to system 1-pressure tests following repair by welding is in accordance with the
- Summer 1978 Addenda of Section XI. Procedures for Eddy Current Examination of heat exchanger tubing, which the Summer 1975 Addenda of ASME Section XI
}, has no provisions for, meets the requirements of the 1974 Edition, Summer ca 1976 Addenda of ASME Section XI. Steam generator tubing examination require-meats are in accordance with Regulatory Guide 1.83, Rev. 1.
