Licensee Action on Previous Inspection Findings Not inspected.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Licensee Identified Items The inspector reviewed the status of the following items:
a ~
Item No. 50-400/79-23-05, Defective Hanger Welds.
The licensee's interim report dated December 19, 1979 reported that reinspection of suspect hangers was complete and that rework of the 192 defective hangers was in progress, with 68 completed.
The letter cited an estimated completion date of January 31, 1980.
Discussions with the site personnel revealed that progress was much s'lower than originally estimated because of the need for scaffolding to complete the rework.
The licensee stated that another interim report would be submitted to
establish a new estimated completion date.
(On January 31, 1980 Region II received the licensee's second interim report dated January 28, 1980 which reported completion of rework and reinspection on 129 of the 192 defective hangers and estimating the new completion date to be March 1, 1980.
b.
Potential CDR - Spool Piece Linear Indication.
On January 18, 1980 the licensee called RII to report that a linear indication approxi-mately 18-inches long by 1/4-inch deep had been discovered on the outside surface of an 8-inch diameter carbon steel spool piece manu-factured by Southwest Fabrication and Welding.
During discussion with the licensee the inspector was informed that a linear indication had been found in several spool pieces during MT inspection of field welds, but in every case but one the indication had been removed with only minor or cosmetic grinding.
The case that had not cleared up had been ground until an 'excavation approximately 1/4-inch deep was made before it, disapperaed.
This indication was in evidence intermittently for about 20-feet of the surface of the pipe; traveled in a spiral fashion around the outside surface; and the longest unbroken segment was about 18-inches long.
The licensee had cut three samples from the pipe for metallurgical examination.
The inspector inspected the affected piping and reviewed the results of the metallurgical exami-nation.
Photomacrographs of cross-sections cut from the piping showed the indication to be a process mark which did not appear to be more than a cosmetic problem.
(On January 29, 1980 the licensee called RII to state that based on the analysis of the problem the item was not reportable because the indication was only 2/ to 5g of the wall thick-ness and the originally reported 1/4-inch depth had been produced by excessive grinding).
The inspector informed the licensee that this item would be assigned item No. 50-400/80-03-04
"Spool Piece Linear Indication" for tracking purposed but would be opened and closed in this report.
c ~
Lamination in Maintenance Rail Support Plates.
On January 18, 1980 the licensee reported that two A-516 grade
Steel plates, 6-inches square were found to have laminations at the plate edge.
During this inspection the licensee informed the inspec-tor that all of the plates involved with the support of the maintenance crane rails were being systematically replaced with material which had been ultrasonically tested for laminations.
In that the replacement work was continuing this item was assigned No. 50-400/80-03-03
"Lami-nation in Maintenance Rail Support Plates".
6.
Inspector Follow-up Items The following previously identified inspector follow-up items were examined during this inspection:
a ~
Item No. 50-400/79-26-01; 50-401/79-26-01; 50-402/79-25-01; 50-403/79-25-01 - "Surveillance of Contractor Welding".
The licensee issued
"3" construction Quality Assurance Procedure CQA-20 "Surveillance of Contractor Welding and Related Activities" on January 23, 1980.
This procedure provides guidance for the inspection criteria and frequency to assure that sub"contractor welding is in accordance with contracted quality requirements.
This item is closed.
b.
Item No. 50-400/79-26-02; 50-401/79-26-02; 50-402/79-25-02; 50-403/
79-25-02 " QA/QC inspection procedures.
The inspector verified that the licensee's visual inspection procedure addresses the inspection of socket weld joints for piping pull-back and weld size.
This item is closed.
7.
Welding Material Control The inspector reviewed the licensee's program for the purchase storage and issue of welding materials for use in safety related applications.
This review included the following:
a.
Site Specification No. 021, "Purchasing Welding Materials for Permanent Plant Construction".
b.
Procedure MP-03 "Welding Material Control".
During the review of MP-03 and discussions with licensee personnel it was determined that covered electrode was being issued from the rod stations in leather pouches as well as the heated electrode caddies, required by the licensee's ASME QA Manual.
While there were no instances where rod issued in leather pouches was used on ASME work the licensee's QA personnel issued DDR-346 to document the situation.
The apparent cause of the problem was that a revision to paragraph 3.18 of MP-03 appears to allow issue of pouches while paragraph 3.26 specifies that issued be in heated caddies.
In that there was no apparent noncompliance with the ASME QA Manual and the licensee's welding Engineering Personnel immediately started preparation on a revision to procedure MP-03 to clarify the requirements the inspector informed the licensee that this would be tracked as inspector follow-up item No. 50-400, 401, 402, 403/80-03-01
"Welding Material Control" pending resolution of DDR-346 and chage to porcedure MP-03.
There were no items of noncompliance or deviations identified in this area of inspectio ~
~
Welding Procedure Specifications and Quality Assurance Procedures Reactor Coolant Pressure Boundary and Other Safety-Related Procedures.
The inspector reviewed the following welding procedure specifications for ASME Piping work:
a.
General Welding Procedure for Stainless Steel, Nickel Base and Nonferrous Weldments MP-07.
b.
General Welding Procedure for Carbon Steel Weldments.
c.
Detail Welding Procedure lAl P"1 Carbon Steel (SMAW).
d.
Detail Welding Procedure 1Bl P-1 Carbon Steel (GTAW).
e.
Detail Welding Procedure SB2 Stainless Steel (GTAW).
f.
Site Specification 030, Field Fabrication and Erection of Power Piping.
g.
Site Specification 031, requirements for Field Welding of Category 1,
2 8 3 or Code Class 1,
2 6 3 Pipe Components.
During this review the inspector noted that the General Welding Procedure (A 6 B above)
and detail welding procedure (C
,
D 8 E above)
requirements for weld weave appear to differ.
This was discussed with the licensee's welding engineer who agreed to resolve the apparent discrepancy by issuing required procedure changes.
The difference is that the General Procedure specifies a maximum weld bead width and the detail procedures specify a
maximum oscillation during welding.
The inspector informed the licensee that clarification of these requirements would be an inspector follow-up item, No. 50"400, 401, 402, 403/80-03"02 "Welding Procedure Weave Width".
There were no items of noncompliance or deviations identified in this area of the inspectio k
