TECHNICAL LETTER REPORT ,

ON FIRST 10-YEAR INTERVAL INSERVICE INSPECTION ]

REQUESTS FOR RELIEF 1 EOR SOUTHERN NUCLEAR OPERATING COMPANY  !

VOGTLE ELECTRIC GENERATING PLANT. UNIT 2 I DOCKET NUMBER 50-425 1

1. SCOPE l

l By letters dated November 30,1998 (Letters LCV-1279, and LCV-1280), the licensee, Southern Nuclear Operating Company, submitted a proposed alternative from the augmented reactor pressure vessel examination required by 10 CFR 50.55a(g)(6)(ii)(A) and other requests for relief from the requirements of the ASME Code,Section XI, for the Vogtle Electric Generating Plant, Unit 2. The proposed alternative and relief requests are for the first 10-year inservice inspection (ISI) interval. Based on our review, the following additionalinformation is required to complete the evaluation of the subject requests for relief.

l

2. INFORMATION REQUIRED 2.? Request for Relief RR-20 (Revision 1)- The Code requires 100% volumetric and surface examinations of the welds identified in the licensee's submittal. The licensee stated that complete examination of these welds is limited by physical limitations due to geometric configuration. The table provided in the licer'see's submittal provides minimalinformation on coverages achieved. Please provide specific description of geometrical constraints or interferences, and drawings or sketches showing the specific configurations of the subject welds to demonstrate the impracticality of meeting the Code examination coverage requirements. This information is needed to support the determination that the subject Code requirements are impractical in accordance with 10 CFR 50 55a(g)(6)(i).

.2.2 ' Request for Relief RR-30 (Part C-B)*- The Code requires 100% volumetric and surface examinations of the welds identified in the licensee's submittal. The licensee stated that complete examination of these welds is limited by physical

l limiiations due to component configuration. The table provided in the licensee's submittal provides minimalinformation on coverages achieved. Please provide specific description of geometrical constraints or interferences, and drawings or

sketches showing the specific configurations of the subject welds to demonstrate the impracticality of meeting the Code examination coverage requirements. This information is needed to support the determination that the subject Code requirements are impractical in accordance with 10 CFR 50.55a(g)(6)(i).

j. Additionally, it is unclear whether relief is for volumetric coverage, surface

]

coverage, or both. Provide clarification detailing the specific examination coverages requiring relief.

l 2.3 Request for Relief RR-34 (Part C-F-1)- The Code requires 100% volumetric and surface examinations of the welds identified in the licensee's submittal. The licensee stated that complete exami-nation of these welds is limited by physical limitations due to geometric configuration, and component obstructions. The table provided in the licensee's submittal provides minimal information on coverages achieved. Please provide specific description of geometrical constraints or I

interferences, and drawings or sketches showing the specific configurations of the subject welds to demonstrate the impracticality of meeting the Code examination coverage requirements. This information is needed to support the determination that the subject Code requirements are impracticalin emdance with 10 CFR 50.55a(g)(6)(i). '

2.4 Request for Relief RR In tne " Code Reauirement for Which Relief is l' Reauested" portion of the submittal, the licensee stated that " Relief is re' quested I

from the requirements of IWA-4000 and IWA-7000 of the 1983 Edition with Addenda through Summer 1983 for piping, valves, and fittings 1 inch NPS and smaller." In the " Basis for Relief" portion of the relief the licensee stated that "...

relief is requested from the record keeping requirements for repairs to piping and components 1-inch NPS and smaller."

.4 IWA-4000 ar.d IWA-7000 contain multiple requirements relating to Repair and Replacements, including; Repair Program Requirements, inspection, Materials,

. Welding and Welder Qualification, Pressure Testing, Examinations, Records, etc.

Based upon the multiple requirements listed in IWA-4000 and IWA-7000 it is  !

unclear what specific code requirement (s) the licensee is seeking relief from. The request for reliaf as written appears generic in nature and does not clearly identify-

- the specific requirement (s) for which relief is required, i.e., is the licensee seeking l relief from all of IWA 4000 and IWA-7000 or only IWA-4700 concerning records? '

Provide the specific code requirements (include paragraphs and subparagraphs) l I

for which relief is required. .
