-
The inspector observed that material certifications for welding
-
materials and structural bolts were not included with the vendor documentation available for review by the inspector as required by Specification 2555-56.
'
This is considered to be an infraction of.s CFR 50, Appendix B,
.
Criterion VII which state.=, in part, " Documentary evidence that material and equipment conform to the procurement requirements
'
.
shall be available at the nuclear power plant site prior
...
to installation or use of such material or equipment."
3.
Bolted connections Section 1-735.2, Bolting Procedure, of USAS B 31.7 requir.es that bolts shall be engaged so that there is visible evidence of complete threading through the nut.
The applicable pump and valve code has similar requirements.
.
.
During observation of work in progress on the decay heat system the inspector observed a numbei of flanged connections which had been bolted up, but in unich the bolt threads were not fully engaged. As exa=ples, it was noted that this was true of sc=e bolts en the following:
Connections to decay heat closed cooling water outlet line a.
flanges on decay heat coolers DHC-1A and DHC-13.
,
b.
Connections to suction and discharge line flanges on decay heat rt=p DHP 1A.
.
Connection of end cover to body of pump DNP 1A.
c.
d.
Connection of cover to body of check valve DHV 103A.
This item is unresolved pending observation of bolted connections
,
by the I&E inspector following inspection of the cocpleted system by the licensee.
,
4.
Purchase So_ecification - Miscellaneous Steel The inspector examined the documentation listed below concerning anchor bolts for the core flood tank support structure.
SP-88, Rev.A, dated January 9, 1976, " Identification of a.
Structures. Systems and Co=ponents under the Meted QA Plan."
This procedure states that Appendix I lists the specifications which are used for purchase and/or installation of structhral systems and co=ponents which are safety related and vuich are required to b controlled under the site QA plan during receipt storage and installition.

Appendix I lists Specification 2555-60,. Sections 3A, SC SD, SH and ISB,and Specification 2555-32, Sections 3A, SA and SB as nuclear safety related.
- b.
Purchase Order No. 9459-02-18-1 Release, dated July 20, 1971,
-
releases Drawing No. 4189 and states that material and fabrication are to be in accordance with the recuirements of I
Specification 2555-32, Sec. SA, and Specification 2555-60, Sec. 53.
Discussions of these documents as well as Specification 2555-60, Section SC and their examination by the inspector leaves some question as to which is the applicable specification since:
(1) 2555-32,- Section SA, does not reference Drawing N.o. 4489.
(2) 2555-60, Section SB, is not listed as nuclear safety
,
-
related on SP-88.
..
(3) 2555-60, Section SC, references Drawing No. 4189, but is not referenced on P.O.
9459-02-18-1.
The inspector observed. that this procedure is generally followed for p ocurement of miscellaneous steel and questioned whether the same problem had been encountered with other purchase orders for such material.
.
This item is unresolved.
5.
PT and Visual Examination - Class N-2 Welds
.
The inspector witnessed performance of visual and liquid penetrant (PT) examination of two socket velds, MU 25-A4 MU 25-B4 by the inspection contractor.
a.
Tha inspection contractor's representative stated that the visual examination of welds was cont'.ucted in accordance with the requirements of UE&C Welding Procedure 20&8.
The inspector reviewed parts of Procedure 20&8 applicable to weld inspection and weld quality r quirements and observed that they are in compliance with USAS B31.7 requirements.
b.
During interpretation of the PT results, the inspector
' observed an indication in the weld crater in each of the two welds examined.

.
The inspection centractor's representative stated that the indications were within acceptable limits outlined i
in their penetrant Procedure NPT-1-NP.
The inspector's review of Procedure NPT-1-NP disclosed that rounded indications up to 3/16" in diameter were acceptable.
'
Procedure NPT-1-NP did not make a distinction between indications and weld crater indications.
E However, Paragraph 3.2.4 o' Burns & Roe (B&R) Specification 2555-72,' tiding and NDT i Nuclear and Auxiliary Piping,"
states in part, "All indications in the weld craters or in the line of fusion between base material and weld metal shall be treated as defects...."
The inspector's review of the above documents, observation of work and
,
discussion with responsible personnel indicates a possible disparity between the specification and procedural requirements.
..
The above apparent disparity is considered unresolved pending a review and interpretation of the specification requirements by the A/E.
6.
Pipine Installation The inspector visually inspected the surge line from the
,
pressurizer to the reactor coolant loop hot leg cnd the core flood line f rom core flood tank "A" to the reactor pressure vessel (RPV).
The lines were found to have been installed and connected in accordance with the FSAR requirements.
Pip e spool pieces, fittings, valves and hangers (where complete)
were installed in accordance with layout and 1sonetric drawings as shown below.
a.
Surge Line This line was installed as shown on FSAR Figure 5.1-5 and in a: ordance with B&W Drawings Nos. 141562, Rev. 14; 141563, Rev. 12; 141564, Rev. 8; 141569, Rev. 10; and FSK-4.
b.
Core Flood Line
~
Thf, line from core flood tank "A" to the RPV was installed as shown on*FSAR Figure 5.1-3 and in accordance with B&R Drawings Nos. 2077, Rev. 7, 2034, Rev. 16; and M.W. Kellogg (MWK) Isometrics 2-4-1 and~2-4-3.
Hangers were installed as shown on MWK Drawing E 2491-4 except that hangers Nos.

This item is considered to be acceptable.
8.
Fit-up and Weldine of Picine
.
The inspector observed the fit-up and align =ent of weld joint 2-DH-V128B, which attaches a 10" line to a cotor operated valve in the decay heat system.
The inspector r.lso witnessed the fit-up of vald joint 1913-1, a 2" pipe to fitting veld in the make-up purification system.
The alignment and fit-up of
'
the above weld joints was in accordance with the require =ents of UE&C Welding Procedure 20&8.
-
After completion of the ::
pass in the above identified welds the inspector visually inspected the rcot pass.
The inspector found the appearance of the weld to be ir. cocpliance with procedural requirements.
The inspector verified the velder's qualification to weld to the applicable procedure and the positions involved.
The inspector selected welds DH'V128A, DH-12SB and 191B-1
^
where the welding wa-beyond the root pass stage for verification of precedural ccapliance. The above welds were performed by qualified welders, using materials certified to meet specification requirements.
