Subject:

Catawba Nuclear Station, Unit 1 Docket No.' 50-413 Request for Relief Serial Number 95-01 Gentlemen: l Please find attached Request for Relief Serial Number 95-01. Submittal of this relief request is necessary because during the Unit I end-of-cycle 8 refueling outage, complete coverage of the subject welds could not be obtained. } I For weld number IRHRB-W3, radiography will be used as an alternate volumetric j examination method. This examination will be performed during the Unit I end-of-cycle 9 refueling outage, which is the first refueling outage in the second ten year inspection interval. Hence, approval of this relief request is requested by June 29,1995, which is the end of the fir.n ten-year inspection interval. { Should you have any questions concerning this relief request, please call L.J. Rudy at l (803) 831-3084. l Very truly yours, j D.L. Rehn LJR/s Attachment 9505310593 950516 PDR ADOCK 05000413 P PDR t q ( amr e,v,te

DUKE POWER COMPANY STATION CATAWBA UNIT 1 10-YEAR INTERVAL REQUEST FOR RELIEF NO. 9S-01 I. System / Component (s) for Which Relief 1.s Requested: ASME Section XI Code Class: 1 Examination Category: B-M-1 Valve - Residual Heat Removal System (ND) - Valve Body To Bonnet Weld Weld Number }1em Number 1ND-37A B12.040.002D ASME Section XI Code Class: 2 Examination Category: C-A Steam Generator - Lower Shell To Transition Cone Weld Weld Number Item Number 1SGC-04B-05 C01.010.002 ASME Section XI Code Class: 2 Examination Category: C-A Residual Heat Removal (ND) Heat Exchanger - Flange To Shell Weld Weld Number Item Number 1RIIRB-W3 C01.010.050 II. Code Requirement: ASME Section XI, Examination Category B-M-1, Pressure Retaining Welds In Pump Casings And Valve Bodies, Table IWB-2500-1, Item No. B12.40 requires a

volumetric examination of essentially 100% of the weld length and adjacent base material on all Valve Body i Welds greater than or equal to 4 inch nominal pipe size as defined by Figure No. IWB-2500-17. Examinations are 1 limited to one valve within each group of valves that are of the-same constructional design, manufacturing method, and that - perform similar functions in the system. ASME Section XI, Examination Category C-A, Pressure Retaining Welds In Pressure Vessels, Table IWC-2500-1, Item No. C1.10 requires a volumetric examination of essentially 100% of the weld length and adjacent base material on Pressure Vessel Shell Circumferential Welds at gross structural discontinuities as defined by Figure No. IWC-2500-1. III. Code Requirement from which Relief is Requested: Relief is requested for the above identified Class 1 Valve Body Weld from meeting the coverage requirements as defined in ASME Section XI, Appendix III, Article 111-4000, III-4420. I Relief is requested for the above identified Class 2 Pressure Vessel Shell Circumferential Welds from meeting the coverage l requirements of ASME Section XI, IWA-2232(a) as defined in l ASME Section V, Article 4, T-441.4.4; T-441.5. 1 IV. Basis for Relief: During the ultrasonic examination of the welds shown in, two directional coverage as required by ASME Section XI, Appendix III and Section V, Article IV as modified by' Code Case N-460 could not be obtained. Causes of these limitations are part geometry, physical barriers, and component / weld material. Where possible, a combination of angles and wave modes were used to maximize the coverage obtained. The weld and base metal at the component inside surface was covered from at least one direction with a minimum of one angle. 1

V. Alternate Examinations or Testing: No additional examinations are planned for Weld ID Numbers, IND-37A and 1SGC-04B-05. In addition to the ultrasonic examination, radiography will be performed on Weld ID Number 1RHRB-W3. For Weld ID Numbers 1ND-37A and 1SGC-04B-05, the use of radiography as an alternate volumetric examination method is not practical due to component thicknesses and geometric configurations. Other restrictions making radiography impractical are the L necessity to use double wall techniques due to inaccessibility of the ID surface and physical barriers prohibiting access for placement of source, film, number bands, etc. We will continue to use the most current ultrasonic techniques available to obtain maximum i coverage for future examinations of these weld numbers. For Weld ID Number 1RHRB-W3, radiography will be used as an alternate volumetric examination method upon completion of a modification to the heat exchanger to allow access to the ID surface for source positioning and the qualification of an acceptable radiographic technique. This radiographic examination will be performed during Unit 1 EOC9, which is the first refueling i l outage in the Second Ten Year Inspection Interval. VI. Justification for the Granting of Relief: Limitations are permanent obstructions and cannot be removed for the components / welds listed in Section I above. Although the coverage requirements of ASME Section XI, as defined in Section V, Article 4 and Section XI, Appendix III could not be met, the amount of l coverage obtained for these examinations provides an acceptable level of quality and integrity. Based on these evaluations,it is Duke Power Company's opinion that the limited coverage will not endanger the health and safety of the general public.

Duke Power Company will perform UT examinations to the extent practical in accordance with ASME Section V, Article 4 and ASME Section XI, Appendix III. VII. Implementation Schedule: These examinations will continue to be scheduled in accordance with the requirements of ASME Section XI for future Inspection Intervals at Catawba Nuclear Station, Unit 1.
