inspector examined the new calibration block and reviewed related quality records for compliance with ASME Section XI requirement Welds for which records were reviewed were as follows:

UNIT 1 Accumulator tanks "A" and "C" Welds IC - 4 No recordable indications 1A-1 No recordable indications 1A - 3 No recordable indications Boron Injection Tank Weld 1-4 No recordable indications UNIT 2 Accumulator tanks "A", "B" and "C" Weld 3 40"-43",144"-147" and 288"-291" No recordable indications Boron Injection Tank Weld - 1 9"-10", 45"-46" and 125"-126" No recordable indications Weld - 2 15"-16", 45"-46" and 125"-126" No recordable indications This item is considered close . Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or devia-tions. One unresolved item identified during this inspection is discussed in paragraph . Service Water Reservoir Improvements This inspection was performed as a followup effort to that conducted on June 11-13, 1985, and documented in Report 50-338,339/85-17. At that time, work activity centered around the installation of buried piping that would be used to connect the new service water valve-house to the existing buried service water lines. During this inspection, work activity included

' installation of structural steel for supports / hangers inside the valve-house; field and shop fabrication of pipe subassemblies for installation into the system; nondestructive examinations including exploratory ultra-sonic examinations on structural steel support columns in the spray pon The overall Service Water Reservoir Improvement program is being implemented under 'the Repair and Replacement rules outlines in ASME Boiler and Pressure Vessel Code,Section XI Rules for Inservice Inspection of Nuclear Power

Plant Component Repairs and replacements will meet the requirements of ASME Section XI 1980 Edition through Winter 1981 Addenda, Subsections IWA, IWB, IWC, and IWD 4000. References to other subsections of the code, pertain to requirements of ASME Section XI 1974 Edition through Summer 1975 Addenda apply. For determining the suitability of replacements, the requirements of Subsections IWA, IWB, IWC and IWD 7000 of the 1980 code and subsequent addenda are used for guidanc The original construction code for the Service Water System is ANSI (formerly USAS) B31.7-1969 Edition with Addenda through 1970. The Service Water System is governed by Class III requirements of that code for design, materials, dimensions, fabrication, assembly, erection, inspection and testin The design basis, system description, design evaluation, and components of the existing Service Water Systems are addressed in the Updated Final Safety Analysis Report Section 9. Structural steel supports / hangers are being constructed and inspected in accordance with AWS D1.1, Structural Welding Code. The inspector inspected the pipe support structure, walked through the valve house to observe welding anc' inspection activities, and inspected completed welds. The '

following completed and in process welds were inspected for compliance with ;

code requirements and regulatory commitment Hangers Weld Location l 1031 West Horizontal, N-289 I 1030 East Lower, N-289 1011 East Lower N-259, -261 1028 West Horizontal N-302

The above examination was performed in accordance with VEPCO's approved MT procedure M-T-1 Rev. 3, written to meet ASME Section V paragraph T-726A.

I Following completion of the examination, the inspector reviewed, material, equipment and personnel qualification for compliance with code requirements and regulatory commitments. Within these areas, the inspector noted the

following: The licensee has identified laminar indications in the structural steel material used as support columrs for the new spray array system in the service water pond. This condition was observed during a weld QC i inspection and subsequently verified with the aid of ultrasonic examinatio The licensee expanded the UT examination and found the

i condition existed in the web .of WIOX49 wide flange steel columns. The

material in question was produced by Inland Steel Company and purchased t through Rockwell Engineering of Blue Island, Illinois. At the close of

this inspection, the UT examination was still in progress. Discussion  !

with the licensee representative disclosed that a 10 CFR 21 report was j being drafted for submittal to the NR ' As stated earlier, structural steel supports inside the valve house are

.

being welded and inspected in accordance with AWS D1.1 Structural Steel Welding Cod In addition, the licensee's Operational Quality Assur-

'

ance Program as delineated in Topical Report VEPI-SA endorses Regula-

tory Guide 1.94 and ANSI Standard N45.2.5-1974 (Standard). Paragraph -

l 7.5, Welding of the Standard, establishes that inspection of structural ,

i steel welds shall be performed in accordance with the provision of AWS D1.1 Section 6 and adds that in-process inspections shall include joint

fitup prior to start of weldin In reference to this inspection requirement, the inspector ascertained that fit up inspections were not

. a QC hold point since this was not. required by AWS-D1.1. Discussions i with VEPC0's construction site management and QC inspectors disclosed i that although structural welding was monitored, three of the four QC inspectors interviewed indicated that no fitup inspections had been verified in any of the supports constructed or on those currently under ,

construction in the valve hous In a meeting with site management, held prior to the exit interview to discuss this matter further, the licensee disagreed with the inspec-tor's position that fitup inspections should be performed prior to '

'

welding as required by the Standard and stated that their interpreta-

. tion of ANSI 45.2.5, paragraph 7.5 was that the requirements for

!

inspection of welds are specified by AWS D1.1, Section 6, and that additional inspections are established by the engineer to be performed l on a surveillance basis. The inspector stated that fitup inspections

'

were an integral part of good welding practices as it provided for

. verification that proper weld gap had been attained; materials, i procedures and personnel were being used and, therefore, the final

weld size would be consistent with design engineering requirement Because of this variance in interpretation of the Standard, the licensee indicated that they would seek an official interpretation from the ANSI committee in charge, and in the mean time proceed with fit-up  ;

inspections of structural steel welds in-process. The inspector agreed

"

to identify the matter as an unresolved item pending a review of the ANSI committee's response, UNR 338, 339/86-26-01, Fit Up Inspection of Structural Steel Weld ,
