-License No.'CPPR-105 1
As a_ result of the inspection conducted on March-16-26, 1987 and in accordance with the'" General, Statement'of Policy and Procedure for NRC Enforcement Actions",.
10CFR2, Appendix C, the following violation was identified:~
L A.'
10CFR50, Appendix ^B, Criterion X states in part "A program for inspection of activities affecting quality shall be established and t
. implemented by or for the organization performing the activity to verify conformance with the documented instructions, procedures, and
' drawings for accomplishing the activity...."'
During the NRC inspection conducted between M' arch 16 and 26,,1987 the following examples of failure to implement quality. control procedures affecting safety related. inspections were identified:
(1)
Inspection Procedure Area' Release - Electrical Inspection IP-12.3, paragraph 5.2.1.2 b, states;" Verify.there are no loose flex conduit connections."
N Inspection Report SPE-326, Inspection Flexible Conduit Connection requires in part... "The inspector shall verify QA-Category I flex conduits submitted by construction for the following criteria:
(a)-
Verify - That the couplers on. both ends of.the flex conduit, as well
'as conduit fittings used for the termination of cables, are hand tight.
According to this. inspection repcrt the. flex conduit connections on 2CHS*MOV81338 satisfactorily met the'above criteria on i

Instrument and Instrumentation Tubing Installation Procedure FCP-507.7, dated January 9, 1986:
a.
paragraph 10.2 states in part... " Turn the nut beyond finger i

paragraph 8.2.4 states in part... " Flex hose, where shown will j
be installed within a single plane as shown on the isometric r
within a tolerance of + or - 1/2 inch to the dimensions specified."
I i
" Flex hose is to be installed with the anti-torque lines at each ~
i l
ferrule in. alignment with each other (same clock position)."

\\
Also, Inspection Procedure 7.2.9, Installation and Fabrication of Instrumentation and Instrumentation Supports, dated January 27, 1987, states in part... "17.1.7 The SQC Inspector shall visually verify l
that the flex hose assembly contains anti-torque indicator lines at each end on the ferrules which are in alignment with each other (i.e.
same clock position)...."
Contrary to the above:
The flex hose depicted on isometric RK-3055 was'not installed within a + or - 1/2 inch plane and the anti-torque arrows were not aligned with each other.

Inspection Procedure 7.2.9 Installation and Fabrication of Instrumentation and Instrumentation Supports, dated January 27,1987 states.in part... "17.1.3 When tubing passes through a sleeve, the minimum dimension between the I.D. of the sleeve and the 0.0. of the tubing shall not be less than 1/2 inch."
Contrary to the above:
The clearance between tubing (Item 68 on drawing 10080-RK-332A-1) and sleeve S-6201 was observed to be approximately 1/8 inch.
(4) Installation procedure 2BVS-970 with Addendum 1 states in part
" Anchors shall be installed perpendicular to the concrete surface within 6 deg, unless otherwise specified.
Beveled washers, minimum thickness equal to standard washer thickness, shall be used to compensate for lack of perpendicularity, exceeding 3 degrees,.... "

Appendix'Ai 3
J Contrary to.the above:
An anchor bolt for aux 1.liary feed pump 2FWE*P22 was installed ~at an-'
angle ofc5 degreestout of perpendicular without a beveled washer such that'the' nut' failed to make full contact with the base.
5 (5) Schneider Sheet Metal' print SM-7-1 for diesel generator buildin'g HVAC
- system ductwork piece SM/26 required the spacing from the left flange
[.
to the first stiffener to-be'16 inches:and from the first stiffener.
i; to the second stiffener to be 16 inches and from there to the other end.of the duct to be 24 inches.
1 Inspection Procedure 7.4.1, Inspection of Q.A. Category I and Other Seismic Heating, Ventilation and Air. Conditioning System Installations, dated December 19,-1985,- states in part'"5.8.1 The SQC Inspector shall perform measurements at his' discretion to verify the ductwork
' size and shape conform to the approved engineering drawings.
Contrary to the above:
The duct'was installed in a position reversed from the above.
In process, final and as-built inspection failed to identify this
deviation from the drawing.

Inspection Procedure 6.3, ' Structural Steel Erection and Bolting, dated November 10, 1986,' states in part "7.1 The contractor may g
l elect to use any of the following tightening methods:
a) Turns-of nut tightening b) Calibrated wrench tightening c) Tightening by use of a direct tension indicator.
The SQC Inspector shall witness the installation of the bolts to assure that the selected procedure is:
properly used and to verify that all bolts are tightened...."
Contrary to the above:
Fan 2HVC*FN241A support is bolted with A325 bolts. One of these bolts was improperly torqued as it could be turned by hand.

6 (8) Inspection Procedure 7.2.9, Installation and' Fabrication of Instrumentation and Instrumentation Supports, dated November 4, 1985 states in part "The SQC Inspector shall verify that the clamps / straps for field run pneumatic tubing supports are located / positioned in accordance with the applicable drawing, and the number of notches and the notch orientation for Girard type supports are in accordance with the applicable drawing...."
i Contrary to the above:
l The outer half of Girard clamp 2RCS-TSA-134A was installed such that the alignment notches.were not aligned.
1 (9) In specification 2BVS-934, " Installation of Heating and Cooling Systems" the licensee commits to follow the specifications of ANSI B31.5 for brazing of copper tubing associated with safety related HVAC systems.
ANSI B31.5 states in part "... Joint Clearance.
The average clearance between' surfaces to be joined shall not be greater than 0.004 inches (0.10 mm) (or a diametrical clearance of 0.008 in. (0.20 mm)).
"The ASNI B31.5 also requires examination of joints and connections for apparent faults.
Contrary to the above:
The copper tubing associated with control room air conditioning units to be inadequately brazed in that the " tee" below valve 2HVC-79 and 1
valve 2HVC-113 did not have a completely filled joint. There was no l
evidence of Quality Control inspection of these joints for clearance prior to brazing or of the completed brazed joint as required above.
l In addition the trending analysis for brazed joints (reference DLC-SQCL-0285-GY - Trend No. TN-006) identified a problem with brazed joints that did not appear to be effectively resolved.
l (10) Procedure 2BVM-236 " Engineering and Quality Control Survey of Component Spacing and Clearances " requires in part a survey for and documentation of clearance violations for all safety related components / systems located in Category I seismic areas.
Procedure 2BVM-220 specifies in Table II a minimum clearance of two inches to accomodate deflection of large bore piping.
Contrary to the above, a clearance of approximately 11/16" was
{
measured between the pipe clamp of hanger No. 2515-PSST-607 and an l
existing structural beam W8X18.

' Contrary to the above vertical welds on a mounting bracket for instrument 2 RCS*LISI321 were found to be 3 inches long in lieu of the drawing requirement of four inches.
(12) Beaver Valley Unit 2 Main One Line and Three Line Diagrams specify test impedance values for Station Service Transformers 2A and 28 and Unit Transformers 2C and 2D.
Contrary to the above, the test impedance values were either partially omitted or incorrectly shown.
Furthermore, the test impedance values.
for transformers 2A and 2B were transposed in the Station Service Voltage and Local Analysis, E-68, and in the Station Service Fault i
Analysis, E-74.
This is a Severity Level V Violation.
Pursuant to the provisions of 10 CFR 2.201, Duquesne Light Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice a written statement or explanation in reply, including: (1) the corrective steps which have been taken and the results achieved; (2) the corrective steps which will be taken to avoid further violations; and (3) the date when full compliance will be achieved.
