Reference:
1) Letter, G.S. Spencer to N.0. Strand, some subject
date June 9, 1980.
2) Letter, D.F. Knuth to all AEC Licensees, " Criterion
for Determining Enforcement Action and Categories of
Nonccmpilance", dated December 13, 1974.
Dear Mr. Spencer:
This letter is in response to your letter of June 9,1980, which
discussed the results of the inspection conducted May 20-23, 1980
of activities authorized by Nuclear Regulatory Commission Construction
Permit Numbers CPPR-154 and CPPR-155. The letter identified two items
of noncompliance categorized in accordance with Reference 2 and re-
quired the Supply System to provide a response to these items.
The specific Nuclear Regulatory Commission Findings, as stated in your
letter, and the Supply System responses are provided in Attachment I
to this letter.
Should you have any questions to desire further information, please
feel free to contact me directly.
Very truly yours,
W

ATTACHMENT I
NUCLEAR REGULATORY COMMISSION FINDING A
10 CFR 50, Appendix B, Criterion V, as implemented by Section 17.4.5 of the
Quality Assurance Program documented in the approved PSAR deviation 18-WP,
states, in part, that " Activities affecting quality...shall be accomplished
in accordance with... instructions, procedures or drawings".
i
Specification No. 3240-4, titled " Piping and Piping Supports - WPPSS Quality
Class I, II, and G" in Division 2, Section 2A, paragraph 6.04h states that
"All pipe welds except socket welds and where otherwise stated on the contract
drawings shall be full penetration welds."
Contrary to the above requirements, the inspector observed on May 20 and 22,
1980, that piping subassenbly No. 3-3CC12-0095A-1 had incomplete root pene-
tration on the inside dianeter of a pipe to elbow weld, specified to be a
full penetration wela, in three areas for a total circumferential distance of
approximately 2.5 inches to 3 inches and that piping subassembly No. 3-3CC24-
06758-8 had incomplete root penetration on the inside diameter of a pipe weld,
specified to be a full penetration weld, for a total circumferential distance
of approximately 12 inches. The above piping subassemblies are carbon steel
and destined for service in the Unit 3 Component Cooling Water System and had
been accepted by Ebasco receipt inspection.
This is an infraction.

NUCLEAR REGULATORY COMMISSION FINDING B
r
10 CFR 50, Appendix B, Criterion V,- as implemented by Section 17.4.5 of the
-
Quality Assurance Program documented in the approved PSAR deviation 18-WP,
,
states, in part, that " Activities affecting quality...shall be accomplished
in accordance with... instructions, procedures or drawings."
Specification No. 3240-4, titled " Piping and Piping Supports - WPPSS Quality
Class I, II and G" in Division 2, Section 2A, paragraph 6.01a states that "All
,
fabrication covered by this specification shall be in accordance with ASME
Section III" and further states in paragraph 6.0ld-iii that "The ends of pipe-
to-pipe, pipe-to-fitting and pipe-to-valve joints shall be aligned as accurately
as practical within the existing commercial codes and standards tolerance of
pipe diameters, pipe wall thickness and out-of-roundness." The ASME B&PV Code,
1974 Edition, Summer 1976 Addenda, Subsection NO, Figure ND4233-1 requires 1/32"
maximum uniform mismatch around joints with concentric centerlines and a 3/32"
maximum mismatch at any one point around the joint for pipe joints with offset
centerlines.
Contrary to the above requirements, the inspector observed on May 20-23, 1980,
that certain piping subassemblies stored at the Saginaw storage area contained
weld joints with offset in excess of ASME B&PV Code requirements. The discre-
pant piping subassemblies has been accepted by Ebasco receipt inspection. The
findings are summarized on the next page.

SUBASSEMBLY NO.
DISCREPANCY
(1) 3-3CC24-04058-5
Inside diameter offset of approximately
5/32" for about 6" of circumferential
distance of one weld
(2)'3-3CC24-0205A-1
Inside diameter offset of approximately
3/16" for about 3" of circumferential
distance on pipe / elbow weld
(3) 3-3CC24-0675B-4
Pipes at one weld joint were approxi-
mately 5/32" offset in inside diameter
due to misalignment for a circumferential
distance of about 6".
(4) 3-3CC24-03-SA-28
Inside diameter offset of approximately
5/32" due to misalignment of pipes to
be joined for about 6" and 8" of circum-
-
ferential distance on first and second
,
welds respectively from elbow opening.
This is an infraction.
'
For both items of Noncompliance, the following actions apply.
CORRECTIVE STEPS WHICH HAVE BEEN TAKEN:
Nonconformance Report number 11934 was prepared on May 22, 1980 to disposition
the pipe spools which were identified by the NRC as exceeding offset limits or
which exhibited incomplete weld penetration. The NCR disposition was to return
the spools to the vendor.
The Supply System issued Stop Shipment Order number 04001 on June 20, 1980 which
requires Supply System evaluation and approval of Associated Piping & Engineering
Corporation's (APSE) corrective action plan and the action taken to prevent re-
currence prior to release of any further shipments.
'The Supply System has established a hold point to perform 100% visual receipt
inspection of all accessable interior / exterior ASME Section III spool welds.
This receipt inspection will determine the acceptability of weld joint offset
-and weld penetration, and shall remain in effect until such time that sufficient
inspection has been performed with acceptable results to obtain a satisfactory
confidence level.
CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATION:
AP&E will visually inspect all accessable welds on ASME Section III pipe spools
now at the WNP-3/5 site.
Inspections will determine the acceptability of weld
joint offset and weld penetration based on contract requirements. Unacceptable

spools will be dispositioned-to either b6 reworked at the site by AP&E utilizing
.
approved procedures or be returned -to AP&E's facility for appropriate action.
The Supply System will perform a sample receipt inspection on other prepurchased
,
materials / components containing similar attributes. Sampling will remain in
effect until such time that a sufficient sample size has been inspected with
,
acceptable results to obtain a satisfactory confidence level.
'
DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED:
i
Full compliance will be achieved upon receipt and approval of AP&E's corrective
action plan and action taken to prevent recurrence.
