i SUMMARY f
Scope:
This routine, unannounced inspection was in the areas of as-buil+
!
verification of Reactor Coolant System (RCS) Prassure Boundary Piping
!
and Safety-Related Piping.
Previously - identified open items were
!
also reviewed, and licensee activities related to NRC Bulletin 88-05 t
were reviewed and observed.
!
Results: In the areas inspected one violation, 425/88-37-01(paragraph 2c)was
identified.
This violation was in the area of RCS Work Observation
and involved the presence of Weld Spatter and gouges on the i
pressurizer surge line piping directly prior to application of
insolation.
Programatic strength was demonstrated by the rapid
evaluation and repair of the above mentioned damage.
However, the potential for weakness is indicated by conditions which allowed the
,
weld spatter and gouges to remain on the Pressurizer Surge Line piping following at least two documented inspections of the RCS piping.

Work Observation and Verification of As-Built Reactor Coolant and Safety-RelatedPiping(37051,49053,49063)
{
The inspector verified the as-build configuration of Reactor Coolant
System (RCS) piping and safety-related piping.
The applicable code for i
piping described herein is the ASME Boiler and Pressure Vessel Code,1974 Edition Sumer 1976 Addenda.
The piping and/or furnished spool pieces
.
were installed by Pullman Power Products (PPP) or Georgia Power Company (GPC). With field welds performed by same.

a.
Work Observation and Verification i
'
Since the available window for work activities associated with installation of piping / components has passed, the inspector elected to complete a field examination of installed piping and associated i
valves, welds, and hangars.
Selected portions of piping and assemblies listed in Paragraph 2b were then compared against "as-built"
,
design drawings and quality documentation.
The following was then determined:

Measures exisc and are in force to protect installed piping and
components / assemblies from construction debris, physical damage, l
and hostile environments.

Installation activities were conducted with reference to
specified procedures and by qualified personnel where required.

Weld Spatter and Gouges on Pressurizer Surge Line A violation of failure to follow procedures was identified during the as-build verification inspection activities conducted on the pressurizer surge line.
The inspector discovered gouges and weld spatter on spool piece 053-S-03; The damage was on the 16" OD section of the pressurizer surge line; damage was located on the top surface of the surge line 22-1/4" from weld 053-W-03 and extending 19-1/4" long x 1-1/2" wide in an axial direction, and on the bottom surface of the surge line,10-1/2" from weld 053-W-03, 7 3/4" long x 1/2" wide, in an axial direction. The gouges were estimated at.015" deep.
The particular section of pipe on which the spatter and gouges were located had been prepared for insulation and was one of the last un-insulated portions on the pressurizer surge line.
This un-insulated portion of the surge line containing the damage was completely wrapped in plastic and according to licensta records, inspected for damage May 19,1988 (prior to primary hydro testing)
and for cleanliness on May 25-26, 1988.
GPC Procedure MD-T-19 Rev.
June 2,1988, "Insulation Installation Inspection" requires insulated piping to be checked for among other things"... are strikes, weld spatter and/or physical damage."
This procedure indicates that walkdown inspections are valid for a period not in excess of 60 days.
Following the inspector's discovery of the damage, a PPP QC inspector recorded the gouges and spatter on Deviation Report (DR) number PP-18142 dated June 29, 1988, for disposition by Westinghouse.
The PPP Inspector indicated that the damage was "As Supplied."
Their disposition was for removal of spatter and gouges by light i
buffing and blending, liquid penetrant te *.ing of the affected areas,
'
and ultrasonic testing to ensure minimum wall requirements of the
'
pipe were not violated.
The completed OR was received in the regional office immediately following this inspection.
Due to failure to identify this damage-especially due to its close proximity to a shop weld which required pre-service inspection, and
following walkdown inspections of the surge line, and failure to follow procedure this will be identified as Violation 425/88-37-01.

Re:ords Reviews t
The inspec+or reviewed pertinent records associated with the piping and assemblies listed in Paragraph 2b to determine if materials used were in conformance with requirenents for naterial certification, installation, and testing per ASME Section II code.
This review included Non-destructive Examination (NDE) associated with the piping required by ASME Section II, certification of pipe utilized, and non-confortnance/ deviation reports.

Independent Inspection Effort Housekeeping (548348), Material Identification and Control (42902B), and Materials Control (429408)
The inspector conducted a general inspection of Unit 2 containment and auxiliary building to observe activities such as housekeeping, material identification and control; material control, and storage.
Within the scope of this inspection, no violations or deviations were found.

Action on Previous Inspection Findings and NRC Bulletins (92701)
a.
(Closed) URI 425/88-33-01, Proper Incorporation of As-Built Corrections to Design Drawings.
A previous inspection identified discrepancies between identification data on penetrations in the Unit 2 containment and corresponding identified data on design drawings.
During this inspection, the inspector verified as-built conditions against design drawings 'in RCS pressure boundary and safety-related piping and no discrepancies were detected.

Licensee efforts to establish their actions and response to requirements of this bulletin were outlined by cognizant licensee personnel in a meeting held on June 28, 1988. The inspector, senior construction resident, and cognizant licensee personnel directly involved in planning the licensee response to NRCB 88-05 attended the meeting.
The inspector also witnessed hardness testing of a flange identified i
by Georgia Power Com;.any as having been suppled by WJM.
The flange
(8" blind flange, SA-105) was installed on a flushing tee adjacent
'
to the discharge isolation valve on Train "A" CCW Pump No 5.
Results of the hardness test indicated the flange was 125 to 130 Brinnell.
This is contrary to ASME SA-105 which requires Brinnell 137 minimu __
