Gentlemen: | |||
Thank you for your letters of January 12, 1987 and March 12, 1987, in response | |||
to our letter dated October 17, 1986. As a result of our review, we find that | |||
additional information, with respect to Items D. I and E in the Notice of | |||
Violation (N0V) and Item B in the Notice of Deviation (N00) is needed. | |||
Specifically, for NOV, Item D.1, you did not address whether or not a review | |||
was performed with respect to the support analysis (No. 01-CSM-2a-II on | |||
conduit No. C23G04066) to assure that the reduced support capacity was | |||
considered. | |||
Please piv/ide us with this information. | |||
For NOV, Item E, it was identified that subsequent to your letter dated | |||
January 12, 1987, additional HVAC organization realignment occurred. | |||
This | |||
action affects your response provided in Item e, of paragraph 3., " Action to | |||
Prevent Recurrence." Please provide the changes caused by this realignment with | |||
respect to the Unit 2 HVAC support field verification program. | |||
For N0D, item 0, base material defect inspection was not identified as an | |||
attribute to be excluded as is required by ERC CPP-007. | |||
Your response that | |||
accurate reinspection cannot be performed following application of coatings is | |||
not consistent with your position regarding inspection for weld defects | |||
through paint. | |||
Inspection of welds in the coated condition and after removal | |||
of the coating was successfully demonstrated by ERC using QI-062. The | |||
observed condition became acceptable in accordance with Ql-QAP-11.1-28 only | |||
after the issuance of DCA-41710 which clarified acceptance criteria. | |||
Therefore, please respond to the deviation as originally requested. | |||
Your response to N00, Items C and D indicates disagreement with the stated | |||
deviations. We have reviewed the additional information you have provided and | |||
have inspected further the as-built condition of Verification Package | |||
1-S-HVDS-075. Based on this review and further inspection, we agree that the | |||
stated deviations did not occur and are withdrawing them. | |||
We have no further questions regarding NOV. Items A, B, C, D.2, F, G, I, and | |||
N00, items A and E, and will review your corrective actions during a future | |||
inspection. | |||

NOTICE OF VIOLATION | |||
ITEM A (446/8602-V-08) | |||
A. | |||
Criterion V of Appendix B to 10 CFR Part 50, as implemented | |||
by Section 5.0, Revision 3, dated July 31, 1984, of the TUGCo Quality | |||
Assurance Plan (QAP), requires that activities affecting quality shall be | |||
prescribed by and accomplished in accordance with documented instructions, | |||
procedures, or drawings. | |||
Paragraph 2.5 of TUGCo Procedure CP-EP-4.6, " Field Design Change Control," | |||
Revision 10, dated April 16, 1984, states, in part, " Design | |||
changes / deviations to specified engineering documents shall be documented | |||
by revision initiated by an Engineering Change Request (ECR), a Design | |||
Change Authorization (DCA) or a Component Modification Card (CMC)." DCA | |||
18,016 required removal of wire strands using a wire stripper to reduce | |||
wire size from #16AWG to #18AWG. | |||
Contrary to the above, wire size reductions were implemented for Unit 2 | |||
termination cabinets, 2-TC22 and 2-TC23, by construction operation | |||
travelers in a manner different than specified on DCA 18,016; no revision | |||
to the DCA had been initiated, nor were either an ECR or CMC initiated. | |||
RESPONSE TO ITEM A (446/8602-V-08) | |||
, | |||
1. | |||
Reason for the Violation: | |||
We admit to the alleged violation for the reasons that follow. | |||
A DCA is not intended or required to show the specific process for | |||
implementing the change. Consequently when the traveler was. prepared, no | |||
review of the DCA was considered resulting in an alternate method being | |||
utilized. | |||
2. | |||
Corrective Actions Taken: | |||
The DCA (No. 18,016) was revised to delete the specifics regarding wire | |||
size reduction. Also, to ensure the method used was acceptable, an | |||
i | |||
engineering evaluation was performed on the cable in question with no | |||
, | |||
adverse effects regarding resistance, etc. being found. | |||
3. | |||
Action to Prevent Recurrence: | |||
The procedure CP-CPM 6.3 defines the traveler program and will be revised | |||
, | |||
to require that a review of the DCA be conducted prior to the traveler | |||
being issued to ensure that if the DCA data contain specifics they are | |||
incorporated into the traveler. | |||
; | |||
4. | |||
Date of como11ance: | |||
The revision to the procedure will be issued by January 9, 1987. | |||

B. | |||
Criterion XVI of Appendix B to 10 CFR Part 50, as implemented by Section | |||
' | |||
16.0, Revision 0, dated July 1,1978, of the TUGC0 QAP, states, in part, | |||
i | |||
" Measures shall be established to assure that conditions adverse to | |||
quality, such as . . . deficiencies, deviations . . . are promptly | |||

identified and corrected." | |||
t | |||
f | |||
! | |||
' | |||
Contrary to the above, the measures established did not assure that the | |||
i | i | ||
following described condition adverse to quality was promptly identified | |||
or promptly corrected. The NRC inspector reviewed a sample of 70 Sample | |||
i | |||
Recheck Request / Report forms, completed by the Inspection Process Control | |||
, | |||
(IPC) group since July 1985, and identified 80 examples where QC | |||
' | |||
inspectors had entered " SAT" inspection attributes in inspection reports | |||
, | |||
1 | 1 | ||
where "NA" (i.e., not applicable) was the correct entry. | |||
; | This condition | ||
; | |||
was identified in the monthly IPC reports beginning with the September | |||
report dated October 11, 1985. Subsequent IPC reports (October and | |||
. | |||
November) characterized this condition as both "a generic problem" and a | |||
significant deficiency and requested that corrective action be taken as | |||
early as December 13, 1985. However, no apparent action has been taken to | |||
4 | 4 | ||
establish how long this condition may have existed before September 1985 | |||
i | |||
nor has corrective action, in a generic sense, been taken. | |||

1. | |||
Reason for the Violation | |||
We admit to the alleged violation for the reascns that follow. | |||
. | . | ||
The practice of entering " Sat" on Inspection Report (IR) attributes when | |||
l | |||
the attribute has more appropriately "N/A" was implemented due to | |||
'l | i | ||
instructions given to QC Inspectors by a field QC Supervisor. The | |||
'l | |||
supervisor instructed his subordinate inspectors to status all IR | |||
attributes as " Sat" whenever the attribute was not unsatisfactory. The | |||
, | |||
practice was considered acceptable by the supervisor since it could not | |||
i | |||
lead to describing an unsatisfactory attribute as satisfactory. This | |||
; | action was taken to avoid the incorrect use of "N/A" when " Sat" or "Unsat" | ||
was more appropriate. Since the practice was not implemented by all | |||
supervisors, inconsistent documentation resulted. | |||
For example, when only | |||
one hilti bolt was located in a room or area, the minimum spacing to other | |||
l | |||
hilti's was considered " Sat" by some QC Inspectors and "N/A" by other | |||
I | |||
; | |||
inspectors. | |||
i | |||
j | |||
The IPC program identified examples where IPC personnel considered the | |||
" Sat" status of these IR attributes to be unacceptable, even though | |||
I | |||
unsatisfactory installations were not identified. These items were | |||
l' | |||
reported as unsatisfactory on Surveillance Recheck / Request Report (SRRR). | |||
QE reviewed SRRRs on an ongoing basis as surveillances were completed and | |||
i | i | ||
the reports received. As stated in the details of the NRC IR, QE | |||
j | |||
concluded that the entry of " Sat" when N/A was applicable, did not render | |||
! | |||
the quality of the item unacce> table and, therefore, did not warrant NCR | |||
! | |||
j | issuance. This practice was, | ||
iowever, considered undesirable from a | |||
! | ! | ||
! | consistent documentation standpoint. This view was shared by QC | ||
i | i | ||
i | Nanagements however, since nonconforming conditions were not involved, | ||
j | i | ||
actions to resolve the inconsistency in documentation practices was not | |||
j | |||
promptly initiated. | |||

RESPONSE TO ITEM B (446/8602-V-06) CONT'D | |||
2. | |||
Corrective Action Taken | |||
Actions taken to resolve inconsistent IR completion involved informal | |||
training of QC Inspectors at the request of the Site QC Supervisor (letter | |||
TUQ-3511 dated 12/10/85). This request emphasized the need to assure | |||
consistent entry of " Sat /Unsat" vs. "N/A" or irs based on the October 1985 | |||
IPC Report. As this instruction was not totally effective in resolving | |||
the inconsistencies, formal classroom training was initiated in February | |||
1986 and completed in May 1986. | |||
It was not and is not considered | |||
necessary to determine the extent or duration this inconsistency existed | |||
since the issue involves inconsistent IR completion only, and does not | |||
alter the status of QC accepted items. | |||
l | |||
3. | |||
Action to Prevent Recurrence | |||
The training described above should prevent recurrence of this violation. | |||
, | |||
Ongoing Quality surveillances and trending would identify further | |||
' | |||
inconsistencies of this nature. The Surveillance Inspection program in | |||
effect since January 1986, has not identified further inconsistencies of | |||
]~ | ]~ | ||
this type. | |||

D. | |||
Criterion V of Appendix B to 10 CFR Part 50, as implemented by Section | |||

5.0, Revision 3, of the Tugco QAP, requires that activities affecting | |||
quality shall be prescribed by and accomplished in accordance with | |||
documented instructions, procedures, or drawings. | |||
Contrary to the above, the following conditions were identified with | |||
respect to Unit 2 conduit supports in which the prescribed activities were | |||
not accomplished: | |||
2. | |||
Section 3.3.1.1 in Revision 14 of Tugco Instruction QI-QP-11.21-1 | |||
requires that the welding symbol for an intermittent fillet weld | |||
be in accordance with standard welding symbols of AWS 2.4-79. | |||
Inspection revealed the existence of intermittent fillet welds on | |||
11 conduit supports in which the applicable, typical support | |||
drawing did not depict an intermittent fillet weld symbol. | |||
RESPONSE TO ITEM 0.2 (446/8602-V-21) | |||
, | , | ||
1. | |||
Reason for the Violation | |||
We admit to the alleged violation for the reasons that follow. | |||
The typical support drawing detail CSM-6C-I depicts an intermittent fillet | |||
weld utilizing the dimensional / hatching method in lieu of providing the | |||
applicable information within the welding symbol. This method of | |||
detailing welding requirements is recognized by AWS 2.4-79, paragraph | |||
4.4.1. | |||
Although TUGC0 Instruction QI-QP-11.21-1, Revision 14 states that | |||
the standard welding symbols will be in accordance with AWS 2.4-79, the | |||
procedure does not explicitly address the acceptable practice of utilizing | |||
the dimensional / hatching method. Only examples of commonly used standard | |||
welding symbols from AWS 2.4-79 are referenced. Additionally, weld | |||
lengths and locations are as depicted on CSM-6C-I. | |||
2. | |||
Corrective Action Taken | |||
It has been the intent of the procedure to include some of the most | |||
commonly used weld symbols to facilitate the inspection process, not to | |||
include all possible weld symbols from AWS criteria which may be used. | |||
TUGC0 Instruction QI-QP-11.21-1 will be clarified to state that standard | |||
welding symbols as referenced in the procedure are only " typical" as | |||
allowed by AWS 2.4-79. | |||
Additionally, a subsequent revision of drawing | |||
2323-S2-0910 sheet CSM-6C-I, more clearly depicts the weld location using | |||
the dimensional / hatching method described above. | |||

2. | |||
Corrective Action Taken Cont'd | |||
Concurrently, an engineering evaluation was conducted with the following | |||
results: | |||
Due to the generic nature of drawing 2323-S2-0910, Sh. CSM-6C-I, Rev. 3, | |||
the plate size (at the welds in question) can vary up to l'-6" max. | |||
In | |||
order to accurately communicate the welding requirements for this joint | |||
design, the engineer utilized the weld symbol to specify the weld size and | |||
minimum length. The typical centerline for acceptable weld spacing for | |||
this generic application was identified separately on the sheet. This is | |||
an acceptable industry practice which meets the intent of AWS 2.4-79. | |||
To assure that the engineering requirements were met during installation, | |||
as-built sketches were made of the eleven (11) supports identified in the | |||
NRC report. An engineering evaluation of these as-builts has verified | |||
that all eleven are in compliance with the welding requirements specified | |||
by this typical drawing. | |||

Criterion X of Appendix B to 10 CFR Part 50, as implemented by Section | |||
10.0, Revision 1, dated July 31, 1984, of the TUGC0 QAP, states, in part, | |||
"A program for inspection of activities affecting quality shall be | |||
established and executed . . . to verify conformance with the documented | |||
instructions, procedures, and drawings for accomplishing the activity." | |||
Contrary to the above, the following examples from Unit 2 HVAC duct | |||
support inspections were observed where the Bahnson inspection program | |||
failed to identify nonconformances with the documented instructions, | |||
procedures, and drawings: | |||
1. | |||
Section 9.1 in Revision 1 of Bahnson Procedure WP-TUSI-001 states, | |||
in part, with respect to intermittent welds, " Weld increments- | |||
shall begin and terminate within 1/8" of the ends of the joints or | |||
length . . . ." Seven HVAC duct supports, however, inspected by | |||
the NRC had intermittent fillet welds which did not begin or | |||
. | terminate within 1/8" of the ends of the joints. | ||
2. | |||
Section 6.5 in Revision 5 of Bahnson Procedure QCI-CPSES-011 | |||
states, in part, with respect to welding, "The Quality | |||
Representative shall make certain that the size, length, and | |||
. | |||
location of all welds conform to the requirements of QCI-CPSES-014 | |||
and DFP-TUSI-003, and to the detailed drawing . . . ." | |||
Independent inspection identified the following conditions in | |||
three HVAC duct supports: | |||
a. | |||
A 2" long, 1/4" fillet weld required by the drawing was | |||
measured as being 1/8" for the full length, | |||
b. | |||
Two, 2-1/2" long,1/8" fillet welds required by the | |||
drawing between the two lateral braces and the main | |||
support were missing. | |||
c. | |||
Two,1-1/2" long,1/8" fillet welds required by the | |||
drawing were measured as being 1-1/4" long. | |||
3. | |||
Section 6.6 in Revision 5 of Bahnson Procedure QCI-CPSES-011 | |||
states, in part, " Weld profiles shall meet the following | |||

The faces of fillet welds may be slightly convex, flat, or | |||
slightly concave . . . Welds shall be visually examined to | |||
determine if the following defects are evident: | |||
... | |||
Undercut shall not exceed 1/32" for materials thicker than | |||
1/4"." | |||
One support was identified in which two welds exhibited 1/16" | |||
undercut for 50 percent of the weld lengths on members which were | |||
1/2" thick. The support also had a 1/4" and a 3/8" weld in which | |||
grinding of the weld produced excess convexity, resulting in an | |||
unacceptable weld profile. | |||

Contrary to the above, verification or checking of a design change, | |||
initiated to resolve a deviation from design documents, did not assure the | |||
adequacy of either the design change' or the disposition of the | |||
nonconformance report (NCR) which documented the deviation. NCR M-80- | |||
00161, initiated on November 6, 1980, addressed the drilling through of a | |||
" probable" template bar, a rebar, and notching another rebar. The | |||
disposition was "Use-As-Is" and referenced DCA No. 9091. The solution in | |||
the DCA stated that, "The condition as described is acceptable." However, | |||
the described condition addressed just one cut bar. | |||
- | |||
RESPONSE TO ITEM F (445/8603-V-04) | |||
1. | |||
Reason for the Violation | |||
We admit the alleged violation for the reasons that follow. | |||
The disposition of NCR M-80-00161 addressed authorization to cut a single | |||
layer of concrete reinforcing steel. The disposition inadvertently failed | |||
to address the remaining conditions due to the nature of the deviations | |||
described as follows: | |||
The bar cut at 2-1/2" depth is authorized by DCA 9091. The bar cut at 5- | |||
1/2" depth is a template bar requiring no authorization for its cutting. | |||
It has no structural significance and is used only for facilitating | |||
installation. The template bar is a construction aide which does not (and | |||
is not required to) appear on design drawings. Therefore, the cutting of | |||
this bar is not a nonconforming condition. The bar notched at 7" depth is | |||
the end of the tail of a bent bar. The cutting of such bars is | |||
generically approved by DCA 243; no additional authorization is required | |||
and hence this is not addressed in DCA 9091. | |||

Action to Prevent Recurrence | |||
The adequacy of nonconformance dispositions has been the issue of a site | |||
initiated Corrective Action Request (CAR-062 dated March 4, 1986) and a | |||
deficiency considered to be potentially reportable under the provisions of | |||
10CFR50.55(e) (SDAR CP-86-48 dated June 16,1986). | |||
The evaluation of these issues include,1) an assessment of the adequacy | |||
of NCR dispositions, and 2) programmatic problems with revising NCRs. | |||
A review of a random sample of NCRs has been conducted to determine the | |||
safety significance of actions resulting from completed dispositions. | |||
This review has provided a high degree of assurance of the adequacy of the | |||
dispositions of NCRs at CPSES. To further ensure that safety concerns do | |||
not exist, a review program encompassing technical review of all | |||
previously closed NCRs with " void," " repair" or "use-as-is" dispositions | |||
is planned. | |||
, | |||
In order to maintain a high degree of confidence that NCR dispositions | |||
- | - | ||
will not result in safety concerns, an interdiscipline review effort has | |||

G. | |||
Criterion X of Appendix B to 10 CFR Part 50, as implemented by Section | |||

* | |||
" A Program for inspection of activities affecting quality shall be | |||

1. | |||
Reason for Violation | |||
i | We admit to the alleged violation for the reasons that follow. | ||
; | |||
i | |||
With the exception of those discrepancies which pertain to supports CTH-2- | |||
i | |||
9774 and CTH-2-10420, the dimension verification discrepancies described | |||
] | |||
in this violation are the result of isolated QC Inspector errors. The | |||
; | ; | ||
reason for the violations associated with supports CTH-2-9774 and CTH-2- | |||
j | |||
10420 are as follows: | |||
j | |||
1 | 1 | ||
For CTH-2-9774, the QC inspector was required by Quality Instructions to | |||
! | ! | ||
j | verify that dimensions shown on "As-built" drawings were within the | ||
j | |||
tolerances specified in QI-QP-11.10-2a. QC inspection has not been | |||
i | required to assure that all dimensions are included on the drawing. Since | ||
l | , | ||
i | |||
the dimensional information referenced in the finding was not on the "As- | |||
i | |||
built" drawing, those dimensional verifications were not performed by the | |||
l | |||
QC inspector. | |||
; | ; | ||
, | |||
For CTH-2-10420, the inspection method used by the inspector to measure | |||
[ | [ | ||
i | the distance between the welded attachments involved measuring the | ||
; | i | ||
; | distance from the ing of the weld on the C-6 channel to the ing of the | ||
l | ; | ||
weld attaching the conduit support to the embedded plate. This inspection | |||
; | |||
method was considered acceptable practice from approximately June 1985 to | |||
l | |||
April 1986 due to the perceived conservatism achieved (i.e., greater | |||
separation). | |||
However, this measuring method resulted in the plus side of | |||
I | I | ||
the 1" tolerance allowed by QI-QP-11.10-2a being exceeded on CTH-2-1042- | |||
' | ' | ||
when measured from the f_ ara of the attached member to the f_tra of the | |||
other welded attachment. | |||

Corrective Action Taken | |||
! | |||
Nonconformance Reports were initiated to address the dimensional | |||
discrepancies. | |||
The dispositions required the drawings to be revised to | |||
' | |||

; | |||
show the "As-built" conditions with the exception of the following NCRs: | |||
l | |||
0 | |||
NCR M-86-201794 addressing CTH-2-9774 was dispositioned "Use-as- | |||
is." | |||
The disposition does not require the location of the | |||
3/8"x4"x5" plate with respect to the C-6 channel to be on the | |||
drawing, only that the weld requirement of the plate to channel is | |||
per design drawing. This weld dimensional requirement was | |||
, | |||
verified by QC at the time of the original QC inspection. | |||
O | |||
Also, per the NCR disposition, DCA 24400 was issued April 2, 1986, | |||
to provide verification criteria when the dimensional location of | |||
, | , | ||
the tray clamp in relation to the C-6 channel is not shown on the | |||
l | l | ||
drawing. QI-QP-11.10-2A has been revised to include this | |||
criteria. | |||

action will be taken as required by the NCR disposition. | |||
Subsequent clarification was received by Engineering whereby the | |||
, | |||
j | |||
separation measurements were to be verified using face-to-face, | |||

unless otherwise detailed on the design drawing. The clarified | |||
method for measuring has been applied since April 1986. | |||

i | Action to Prevent Recurrence | ||
j | i | ||
! | |||
i | Each of the QC Inspectors involved with acceptance of the discrepant | ||
! | installations identified have been made aware of their errors. To | ||
l | i | ||
! | determine the need for further corrective action, the performance of these | ||
j | |||

reinspection results. | |||
Based on this review it has been determined that | |||
i | |||
the involved inspectors have demonstrated a high degree of accuracy in the | |||
! | |||
performance of inspections and no further corrective action is needed. | |||
l | |||
Per the disposition of NCR N-86-201794, no further action is required for | |||
! | |||
the dimensional 3/8"x4"x5" plate-to-channel finding. However, the | |||
revision of QI-QP-11.10-2a should prevent recurrence of the erroneous | |||
j | |||
dimensional location of the tray clamp plate-to-the channel finding. | |||

portion of the 50-foot increment of this weld shall be radiographed." | |||
Contrary to the above, the required radiography of the remaining portion | |||
of a 50' increment of weld was not performed even though one of the two | |||
second 12" radiographs (No. 146T2) at seam P84 in the Unit 2 containment | |||

1. | |||
Reason for the Violation | |||
. | . | ||
At the time of inspection, procedures failed to clearly describe the | |||
conditions for initiating a DR or NCR. | |||
2. | |||
Corrective Action Taken | |||
Recently issued Nuclear Engineering and Operations (NE0) procedures | |||
clearly define the site guidelines for deficiency and nonconformance | |||
reporting. | |||
Implementing procedures will be revised to include | |||
requirements of the appropriate NE0 procedures. | |||

Action to Prevent Recurrence | |||
The corrective action should prevent recurrence of this part of the | |||

Reason for the Violation | |||
All prior revisions of STA-404, " Control of Deficiencies", have required | |||
Quality Assurance to determine if the deficiency "may cause or has caused | |||
a nonconformance." This part of the violation occurred because STA-404 | |||

RESPONSE TO ITEM A (445/8603-D-14) | |||
1. | |||
Reason For Deviation | |||
! | |||
{ | |||
We admit to the alleged deviation for the reasons that follow, | |||
i | |||
! | |||
The primary reasons for the deviation are imprecise guidance in QI-019 and | |||
j | |||
inspector misinterpretation of that guidance. | |||
Prior to Revision 3, QI-019 | |||
did not specifically address allowable clearances in the gravity direction | |||
. | |||
! | ! | ||
for dead weight, box frame supports. Although these clearance | |||
; | |||
requirements were covered in ERC Inspector training, some confusion | |||
! | |||
existed over eleven inspection packages in which the box frame support | |||
i | i | ||
drawings showed the pipe in contact with the support but specified no | |||
! | ! | ||
allowable clearance value. | |||
ERC decided to revise QI-019 to reflect | |||
I | |||
clearance requirements as taught in inspector training, and to reinspect | |||
! | ! | ||
those eleven packages. As a result, ERC Description Memorandum QA/QC-RT- | |||
1436 (dated 2/10/86) was issued to describe the Revision 3 changes to | |||
section 5.3.5(A) of QI-019. | |||
(The memo erroneously stated that no | |||
previously issued packages were affected by the changes, when in fact | |||
Attachment A to the memo listed the eleven (11) packages requiring | |||
! | |||
l | |||
reinspection. Recognizing the error in the memo, ERC issued Revision 1 to | |||

ITEM A (445/8603-D-14) CONT'D | |||
1. | |||
Reason for Deviation (cont'd) | |||
Subsequent to the issuance of QA/QC-RT-1436, listing the eleven (11) | |||
packages to be reinspected, ERC became aware of past inspector confusion | |||
over allowable clearances even when zero inches (0") clearance in the | |||
gravity direction was specified on the drawing. | |||
ERC then issued | |||
Supplemental Inspection Instructions requiring reinspection of all box | |||
frame, dead weight supports in the small bore population. | |||
In total, 32 | |||
packages were reinspected resulting in 9 Deviation Reports regarding zero | |||
l | |||
clearance in the gravity direction. | |||
Package No. I-S-SBPS-051 was among | |||
those reinspected, and a clearance violation in the gravity direction was | |||
noted on Deviation Report No. I-S-SBPS-051-DR3 and subsequently on NCR M- | |||
23400N R-1. Attachment A to memo QA/QC-RT-1436 was not revised to reflect | |||
i | |||
these reinspections. | |||
2. | |||
Corrective Action Taken | |||
Corrective Action has been completed with the issuance of Rev. 3 to QI-019 | |||
and with the reinspection of all affected packages as of May 30, 1986. | |||
~ | |||
Revision 2 to QA/QC-RT-1436 was issued on November 11, 1986, and contains | |||
a note referring to the reissuance of all affected packages. | |||
3. | |||
Action to Prevent Recurrence | |||
No action to prevent recurrence is contemplated for the Small Bore | |||
population as reinspection efforts are complete and Rev. 3 to QI-019 has | |||
been issued. As a result of CAR-16, ERC QI procedures were reviewed in | |||
meetings between engineers and inspectors to ensure clarity and | |||
consistency of the procedures. The need to clarify box frame support | |||
clearance criteria in QI-019 was identified in a January 11, 1986, CAR-16 | |||
meeting. | |||

Revision 3) for applicability in developing the QI-029 inspection | |||
; | |||
checklist. | |||
Inspection for excessive grinding due to welding defects on | |||
i | |||
base materials was not included on the checklist for the following | |||
i | |||
reasons. While excessive grinding may be readily detected after initial | |||
i | |||
installation is complete, it cannot be accuratelv reinspected following | |||
i | |||
application of coatings. | |||
In most cases, the grinding performed to remove | |||
1 | |||
weld defects would not be detectable through paint at all. | |||
Further, while | |||
! | |||
the ASME Code Subsection NF stipulates that grinding to remove weld | |||
defects may not encroach on minimum base metal thickness, there is no code | |||
' | ' | ||
: | |||
requirement to inspect for other types of defects in base metal as a | |||
! | |||
result of the welding process. Once coatings have been applied, it is | |||
l | |||
difficult to distinguish between markings due to grinding versus other | |||
i | |||
potential causes. | |||
Paint removal to inspect for potential excess grinding | |||
i | |||
is impractical. | |||
In addition, paint removal methods also remove some base | |||
; | |||
! | metal in the process, making an accurate determination of the depression | ||
l | j | ||
i | depth impossible. | ||

RESPONSE TO ITEM B (445/8603-D-18) CONT'D | |||
engineer concluded that inspection for excessive grinding of base metal | |||
through paint is not a recreatable characteristic of the welding | |||
attribute. | |||
In accordance with ISAP VII.c, attributes or subattributes | |||
which are deemed not recreatable are not included on inspection | |||
checklists. | |||
However, due to NRC inspector concerns, the ERC inspector wrote an Out-of- | |||
Scope observation for Verification Package No. I-S-LBSN-065 noting | |||
potential excess grinding on the pipe support base metal. A | |||
Nonconformance Report was subsequently issued and is currently being | |||
evaluated to disposition the Out-of-Scope observation. | |||
It should also be noted that the nominal flange thickness for this pipe | |||
support (a W4 x 13 structural shape) is 3/8 inch. | |||
In accordance with QI- | |||
QAP-11.1-28, a depression depth of 1/16 inch (the observed condition) is | |||
. | |||
thus acceptable. | |||

C. | |||
Section 5.2 of ERC Procedure CPP-022, Revision 0, states, in part, " Paint | |||
shall be removed from the weld connections which have been inspected | |||
through paint . . . . Results of these visual inspections shall be | |||
documented and include, as a minimum, criteria utilized, (and) any | |||
discrepancies." Section 5.2.D of ERC QI-062, Revision 0, states, " Verify | |||
surface of welds are sufficiently free of overlap, abrupt ridges and | |||
ripples so proper interpretation of radiographic and/or other required NDE | |||
could be accomplished." | |||
In deviation from the above, ERC quality inspection documented in | |||
Verification Package No. I-S-NPBW-014 that the surface of welding which | |||
attached item 1 to support steel identified on Drawing FW-1-019-901A-C57W | |||
was acceptable. | |||
Independent inspection identified, however, that after | |||
removal of coatings the weld surface was unacceptable. | |||
> - | Subsequent to the | ||
NRC inspection, ERC personnel issued a deficiency report documenting the | |||
rejectable weld condition. | |||
RESPONSE TO ITEM C (445/8603-D-17) | |||
We deny the alleged deviation for the reasons that follow. | |||
> - | |||
The surface of the subject weld (with paint on) was inspected per packages | |||
I-S-PWRE-006 and I-S-NPBW-014. Weld surface irregularities were noted by | |||
the inspectors and the attribute rejected in each package. The rejection | |||
was documented on DR No. I-S-PWRE-006 DR2. | |||
(No DR was written for the | |||
NPBW package, as the second part of the inspection called for weld surface | |||
examination with the paint removed.) | |||
Following paint removal, the weld surface could be more easily examined. | |||
The weld surface attribute was accepted in I-S-NPBW-014 and later in | |||
Overview Inspection Report No. 24-008 (I-S-PWRE-006). Due to NRC concerns | |||
about the weld surface, however, an independent Level III inspector was | |||
brought to CPSES to examine the weld. The report by this Level III | |||
inspector stated, "This writer found this weld to be acceptable except in | |||
some cases where abrupt ridges and valleys were pronounced due in part to | |||
limited grinding of the surface. | |||
It should be noted that this is a | |||
judgement interpretation that would vary from weld to weld and in some | |||
cases the final magnetic particle test may require additional surface | |||
preparation influenced by the specific MT method used." The independent | |||
Level III inspector concluded: "It is evident that the magnetic particle | |||
examination would be the last determining factor as to the adequacy of the | |||
weld." | |||
A review of the original magnetic particle examination of the weld | |||
performed by Chicago Bridge and Iron indicated the acceptability of the | |||
weld and weld surface. Based on the judgement of the ERC inspectors, the | |||
independent Level III inspector report, and the acceptance of the weld in | |||
the original NDE report, ERC concluded the weld surface was acceptable. | |||
However, due to continuing NRC concerns regarding the interpretation of | |||
the independent Level III inspector's report, Deviation Report No. I-S- | |||
NPBW-014 DR1 was generated. | |||

To resolve the issues, a Brown and Root Level III inspector performed a | |||
Magnetic Partical Test on the weld. On the basis of the test report | |||

Section 5.1.1 of Revision 2 to ERC Procedure CPP-008 states, in part, | |||
. . . should an attribute appear on the generic checklist and not be | |||
" | |||
applicable to the specific item, the engineer indicates 'N/A' and provides | |||
reasonable justification for the entry." | |||
In deviation from the above, an independent inspection of Verification | |||
Package No. I-S-HVDS-075, support DG-844-2K-1J, revealed that Sections | |||
2F.1, ?F.2, and 2F.3 in the checklist for QI-035, dealing with embed | |||
plates and spacing violations, had been "N/A'd" by the engineer. | |||
Further, the noted justification for this entry was "No Embedded PLs." | |||
However, independent inspection identified the existence of an embed plate | |||
with dimensions of approximately 20' X 8". | |||
RESPONSE TO ITEM D (446/8602-D-13) | |||
We deny the alleged deviation for the reasons that follow. | |||
Sections 2F.1, 2F.2, and 2F.3 for Verification Package No. I-S-HVDS-075 | |||
had been "N/A'd" by the ERC engineer. The justification for this entry | |||
was "No Embedded PLs". A subsequent review of this package by ERC has | |||
,~ | |||
! | |||
revealed that a deviation does not exist. The ERC Engineer correctly | |||
N/A'd these attributes. | |||
Quality Instruction (QI) 035, " Reinspection of HVAC Duct Supports" | |||
delineates the inspection requirements to be performed for this population | |||
(HVDS). | |||
Section 5.2.2F of this QI addresses Welded Attachments to | |||
Embedded Plates. | |||
For the 2F. attributes to be inspected, the duct support | |||
has to be attached (welded) to the embedded plates. Verification Package | |||
No. I-S-HVDS-075 contains support DG-844-2K-lJ for inspection. | |||
Support | |||
DG-844-2K-1J is not welded to an embed plate, therefore these attributes | |||
(2F.1, 2F.2, and 2F.3) cannot be reinspected. Therefore, the ERC engineer | |||
correctly N/A'd these inspection attributes. | |||
During the course of this review and subsequent discussions with the NRC | |||
it was brought to the attention of ERC that NRC had a concern with | |||
Attribute 4C.3, "Hilti to Embedded Plate Edges". The ERC inspector had | |||
originally accepted this attribute. QI-035, Section 4C.3 requires the ERC | |||
inspector to " verify that the minimum distance of each Hilti anchor to any | |||
adjacent embedded plate (or Nelson stud, if available) meets the | |||
requirements of Attachment 6.17..." | |||
The required minimum for a 1-inch | |||
Hilti to the edge of an embedded plate is 7-1/2 inches. | |||
Subsequent | |||
inspection of attribute 4C.3 revealed a 1 inch Hilti installation 7/8-inch | |||
from an embedded plate. | |||
Verification Package No. I-S-HVDS-075, was reissued and a deviation report | |||
I-S-HVDS-075-DR4 issued by the ERC inspector on July 31, 1986, identifying | |||
, | |||
the discrepant condition. | |||
In addition, Nonconformance Report No. M-86- | |||
202172X was issued on September 2, 1986 and has not yet been | |||
dispositioned. | |||

j | on the drawing. The member whose lengths were not shown, spanned two | ||
l | |||
members. These members were verified, under the configuration attribute, | |||
; | |||
to ensure that they spanned the two members. However, a tolerance was not | |||
j | |||
applied to the member length, because it was not considered safety | |||
significant. | |||
; | |||
Therefore, attribute 2D. was accepted for the aforementioned members. The | |||

attribute was not safety significant in those cases. | |||

RESPONSE TO ITEM E.2 (446/8602-D-11) CONT'D | |||
1. | |||
Reason for Deviation (cont'd) | |||
Subsequent discussions with the ERC inspector revealed that a six inch | |||
rule had also been used to verify the skewed weld leg size. The six inch | |||
rule was used to measure the leg that had the member "end prepped." The | |||
inspector apparently accepted the attribute on that basis. Based on | |||
further discussions with the ERC inspector, NRC inspector, and TUGC0 QA/QC | |||
personnel it was determined that the ERC Level III should verify attribute | |||
38. The Level III inspector successfully measured one leg of the skewed | |||
fillet weld using a skewed weld gage. The Level III inspector determined | |||
that the second leg of the weld could not be measured in the manner | |||
demonstrated by the ERC inspector. The measured leg size was 3/8-inch. | |||
Measurement of the second leg was found to be indeterminate. Therefore, a | |||
deviation does exist for Verification Package No. I-S-HVDS-075 attribute | |||
i~ | 38. | ||
2. | |||
Corrective Action Taken | |||
i ~ | |||
ERC Deviation Report (DR) number I-S-HVDS-075-DR5 was prepared to document | |||
the undersized weld. | |||
. | |||
3. | |||
Action to Prevent Recurrence | |||
< | |||
t | t | ||
For Verification Package No. I-S-HVDS-075, where inspector error was | |||
' | |||
evident, the inspector and the lead inspector and population (ERC) | |||
engineer discussed specifics to determine why the error occurred. | |||
, | , | ||
Documented evidence of these discussions is available in the file for NRC | |||
review. | |||
At the discretion of the lead inspector, formal and informal group | |||
; | meetings were held to discuss inspector error on a generic basis. These | ||
Miscussions allowed appropriate information to be disseminated to various | |||
: | cognizant ERC inspectors. | ||
An Overview Inspection Program was implemented to reinspect a sample of | |||
, | |||
each inspectors work. | |||
Results of the Overview Inspection Program are | |||
j | |||
complete and are available for NRC review. The inspector for Verification | |||
; | |||
Package No. I-S-HUDS-075 had an overall error rate of 0.18% or 0.0018. | |||
This number is significantly less than one percent and is based on 3279 | |||
, | |||
l | |||
: | |||
decision points reviewed by Overview Inspection with 6 in disagreement. | |||
l | |||
Based on these Overview results, we believe that no further action to | |||
prevent recurrence is required. | |||

NOTICE OF DEVIATION | |||
ITEM E.3 (445/8603-D-13) | |||
E. | |||
Section 4 of Revision 3 to ERC Procedure CPP-009 states, in part, | |||
" Qualified QA/QC Review Team personnel perform field reinspections of | |||
specific hardware items and reviews of appropriate documents in accordance | |||
with' approved instructions . . . ." | |||
In deviation from the above, the following examples were noted where field | |||
reinspections of hardware items were not performed in accordance with | |||
approved instructions: | |||
E.3. | |||
Attribute 1.f in Section 5.2.6.2 of QI-025, Revision 2, states, in | |||
part, " Ensure that a minimum of 2 inches clearance is maintained, | |||
including pipe insulation, with respect to other piping when one | |||
or both lines have an operating temperature of 2000 F or | |||
_ | greater . . . ." | ||
For Verification Package No. I-M-LBC0-148, the | |||
ERC inspector signed off this attribute as acceptable, even though | |||
there were three cases where the minimum separation criteria were | |||
not met and no documentation existed justifying this condition. | |||
The three instances were as follows: | |||
a. | |||
Line 2-CC-1-060-152-3 was in contact with the inspected | |||
_ | |||
line at a location 6' 6" north of wall 7-S and 10' west of | |||
wall D-S. | |||
The two lines were parallel and were in contact | |||
for about 4'. | |||
b. | |||
Line 2-CC-1-061-152-3 was in contact with the inspected | |||
line at a location 12'6" north of wall 7-S and about 8' | |||
west of wall D-S. | |||
c | |||
Line 1-CC-1-062-152-3 was closer to the inspected line | |||
than the allowable 2" at a location 6' 6" north of wall 7- | |||
S and 7' 6" west of wall D-S. | |||

RESPONSE TO ITEM E.3 (445/8603-D-13) | |||
1. | |||
Reason for Deviation | |||
We admit to the alleged deviation for the reasons that follow. | |||
Investigation by ERC confirmed the above findings identified by the NRC. | |||
Therefore, a deviation does exist for Verification Package No. I-M-LBC0- | |||
148, attribute 1.f, which was incorrectly accepted by the ERC inspector. | |||
2. | |||
Corrective Action Taken | |||
Deviation Report (DR) number I-M-LBCO-148-DR-3 was prepared on August 28, | |||
1986, to document the existence where the minimum separation criteria was | |||
not met. Nonconformance Report (NCR) number M-25340N was generated as a | |||
result of the DR to disposition the above conditions. | |||

Action to Prevent Recurrence | |||
In cases where inspector error was evident, the inspector and the lead | |||
! | ! | ||
inspector or population engineer discussed specifics to determine why the | |||
error occurred. | |||
i | |||
Documented evidence of these discussions is available in the file for NRC | |||
3 | review. | ||
3 | |||
At the discretion of the lead inspector, formal and informal group | |||
meetings were held to discuss inspector errors on a generic basis. These | |||
, | , | ||
; | |||
discussions allowed appropriate information to be disseminated to various | |||
cognizant ERC inspectors. Additionally, this finding was discussed and | |||
documented with all overview inspectors on June 10, 1986. The overview | |||
, | , | ||
inspectors were instructed to review in detail all NCRs in each overview | |||
< | < | ||
l | l | ||
! | inspection package. | ||
}- | ! | ||
An Overview Inspection Program was implemented to reinspect a sample of | |||
}- | |||
each inspectors work. Results of the Overview Inspection Program are | |||
complete and are available for NRC review. The. inspector for Verification | |||
Package No. I-M-LBC0-148 had an overall error rate of 1.12% or 0.0112. | |||
This number of errors is slightly more than one percent and is based on | |||
2675 decision points reviewed by Overview Inspection with 30 | |||
disagreements. Based on the Overview Inspection, we believe that no | |||
further action to prevent recurrence is required. | |||
4. | |||
Date of Comoliance | |||
Corrective action will be completed commensurate with the final | |||
disposition of nonconformance report M-25340N which is expected by May 1, | |||

Gentlemen:
Thank you for your letters of January 12, 1987 and March 12, 1987, in response
to our letter dated October 17, 1986. As a result of our review, we find that
additional information, with respect to Items D. I and E in the Notice of
Violation (N0V) and Item B in the Notice of Deviation (N00) is needed.
Specifically, for NOV, Item D.1, you did not address whether or not a review
was performed with respect to the support analysis (No. 01-CSM-2a-II on
conduit No. C23G04066) to assure that the reduced support capacity was
considered.
Please piv/ide us with this information.
For NOV, Item E, it was identified that subsequent to your letter dated
January 12, 1987, additional HVAC organization realignment occurred.
This
action affects your response provided in Item e, of paragraph 3., " Action to
Prevent Recurrence." Please provide the changes caused by this realignment with
respect to the Unit 2 HVAC support field verification program.
For N0D, item 0, base material defect inspection was not identified as an
attribute to be excluded as is required by ERC CPP-007.
Your response that
accurate reinspection cannot be performed following application of coatings is
not consistent with your position regarding inspection for weld defects
through paint.
Inspection of welds in the coated condition and after removal
of the coating was successfully demonstrated by ERC using QI-062. The
observed condition became acceptable in accordance with Ql-QAP-11.1-28 only
after the issuance of DCA-41710 which clarified acceptance criteria.
Therefore, please respond to the deviation as originally requested.
Your response to N00, Items C and D indicates disagreement with the stated
deviations. We have reviewed the additional information you have provided and
have inspected further the as-built condition of Verification Package
1-S-HVDS-075. Based on this review and further inspection, we agree that the
stated deviations did not occur and are withdrawing them.
We have no further questions regarding NOV. Items A, B, C, D.2, F, G, I, and
N00, items A and E, and will review your corrective actions during a future
inspection.

Attachment 1
ITEM A (446/8602-V-08)
A.
Criterion V of Appendix B to 10 CFR Part 50, as implemented
by Section 5.0, Revision 3, dated July 31, 1984, of the TUGCo Quality
Assurance Plan (QAP), requires that activities affecting quality shall be
prescribed by and accomplished in accordance with documented instructions,
procedures, or drawings.
Paragraph 2.5 of TUGCo Procedure CP-EP-4.6, " Field Design Change Control,"
Revision 10, dated April 16, 1984, states, in part, " Design
changes / deviations to specified engineering documents shall be documented
by revision initiated by an Engineering Change Request (ECR), a Design
Change Authorization (DCA) or a Component Modification Card (CMC)." DCA
18,016 required removal of wire strands using a wire stripper to reduce
wire size from #16AWG to #18AWG.
Contrary to the above, wire size reductions were implemented for Unit 2
termination cabinets, 2-TC22 and 2-TC23, by construction operation
travelers in a manner different than specified on DCA 18,016; no revision
to the DCA had been initiated, nor were either an ECR or CMC initiated.
RESPONSE TO ITEM A (446/8602-V-08)
,
1.
Reason for the Violation:
We admit to the alleged violation for the reasons that follow.
A DCA is not intended or required to show the specific process for
implementing the change. Consequently when the traveler was. prepared, no
review of the DCA was considered resulting in an alternate method being
utilized.
2.
Corrective Actions Taken:
The DCA (No. 18,016) was revised to delete the specifics regarding wire
size reduction. Also, to ensure the method used was acceptable, an

Criterion XVI of Appendix B to 10 CFR Part 50, as implemented by Section
'
16.0, Revision 0, dated July 1,1978, of the TUGC0 QAP, states, in part,
i
" Measures shall be established to assure that conditions adverse to
quality, such as . . . deficiencies, deviations . . . are promptly
'
!
l
identified and corrected."
t
f
!
'
Contrary to the above, the measures established did not assure that the
i
following described condition adverse to quality was promptly identified
or promptly corrected. The NRC inspector reviewed a sample of 70 Sample
i
Recheck Request / Report forms, completed by the Inspection Process Control
,
(IPC) group since July 1985, and identified 80 examples where QC
'
inspectors had entered " SAT" inspection attributes in inspection reports
,
1
where "NA" (i.e., not applicable) was the correct entry.
This condition
was identified in the monthly IPC reports beginning with the September
report dated October 11, 1985. Subsequent IPC reports (October and
.
November) characterized this condition as both "a generic problem" and a
significant deficiency and requested that corrective action be taken as
early as December 13, 1985. However, no apparent action has been taken to
4
establish how long this condition may have existed before September 1985
i
nor has corrective action, in a generic sense, been taken.

1.
Reason for the Violation
We admit to the alleged violation for the reascns that follow.
.
The practice of entering " Sat" on Inspection Report (IR) attributes when
l
the attribute has more appropriately "N/A" was implemented due to
i
instructions given to QC Inspectors by a field QC Supervisor. The
'l
supervisor instructed his subordinate inspectors to status all IR
attributes as " Sat" whenever the attribute was not unsatisfactory. The
,
practice was considered acceptable by the supervisor since it could not
i
lead to describing an unsatisfactory attribute as satisfactory. This
action was taken to avoid the incorrect use of "N/A" when " Sat" or "Unsat"
was more appropriate. Since the practice was not implemented by all
supervisors, inconsistent documentation resulted.
For example, when only
one hilti bolt was located in a room or area, the minimum spacing to other
l
hilti's was considered " Sat" by some QC Inspectors and "N/A" by other
I
inspectors.
i
j
The IPC program identified examples where IPC personnel considered the
" Sat" status of these IR attributes to be unacceptable, even though
I
unsatisfactory installations were not identified. These items were
l'
reported as unsatisfactory on Surveillance Recheck / Request Report (SRRR).
QE reviewed SRRRs on an ongoing basis as surveillances were completed and
i
the reports received. As stated in the details of the NRC IR, QE
j
concluded that the entry of " Sat" when N/A was applicable, did not render
!
the quality of the item unacce> table and, therefore, did not warrant NCR
!
issuance. This practice was,
iowever, considered undesirable from a
!
consistent documentation standpoint. This view was shared by QC
i
Nanagements however, since nonconforming conditions were not involved,
i
actions to resolve the inconsistency in documentation practices was not
j
promptly initiated.

2.
Corrective Action Taken
Actions taken to resolve inconsistent IR completion involved informal
training of QC Inspectors at the request of the Site QC Supervisor (letter
TUQ-3511 dated 12/10/85). This request emphasized the need to assure
consistent entry of " Sat /Unsat" vs. "N/A" or irs based on the October 1985
IPC Report. As this instruction was not totally effective in resolving
the inconsistencies, formal classroom training was initiated in February
1986 and completed in May 1986.
It was not and is not considered
necessary to determine the extent or duration this inconsistency existed
since the issue involves inconsistent IR completion only, and does not
alter the status of QC accepted items.
l
3.
Action to Prevent Recurrence
The training described above should prevent recurrence of this violation.
,
Ongoing Quality surveillances and trending would identify further
'
inconsistencies of this nature. The Surveillance Inspection program in
effect since January 1986, has not identified further inconsistencies of
]~
this type.

Independent inspection revealed a decision point which had not
been included in the isometric drawing by the Field Engineer. One
support was observed in which a 3/8" Hilti bolt had been
installed. The applicable typical drawing specified a 1/2" Hilti
, -
bolt with the option of using a 3/8" Hilti bolt, provided the

quality shall be prescribed by and accomplished in accordance with
documented instructions, procedures, or drawings.
Contrary to the above, the following conditions were identified with
respect to Unit 2 conduit supports in which the prescribed activities were
not accomplished:
2.
Section 3.3.1.1 in Revision 14 of Tugco Instruction QI-QP-11.21-1
requires that the welding symbol for an intermittent fillet weld
be in accordance with standard welding symbols of AWS 2.4-79.
Inspection revealed the existence of intermittent fillet welds on
11 conduit supports in which the applicable, typical support
drawing did not depict an intermittent fillet weld symbol.
RESPONSE TO ITEM 0.2 (446/8602-V-21)
,
1.
Reason for the Violation
We admit to the alleged violation for the reasons that follow.
The typical support drawing detail CSM-6C-I depicts an intermittent fillet
weld utilizing the dimensional / hatching method in lieu of providing the
applicable information within the welding symbol. This method of
detailing welding requirements is recognized by AWS 2.4-79, paragraph
4.4.1.
Although TUGC0 Instruction QI-QP-11.21-1, Revision 14 states that
the standard welding symbols will be in accordance with AWS 2.4-79, the
procedure does not explicitly address the acceptable practice of utilizing
the dimensional / hatching method. Only examples of commonly used standard
welding symbols from AWS 2.4-79 are referenced. Additionally, weld
lengths and locations are as depicted on CSM-6C-I.
2.
Corrective Action Taken
It has been the intent of the procedure to include some of the most
commonly used weld symbols to facilitate the inspection process, not to
include all possible weld symbols from AWS criteria which may be used.
TUGC0 Instruction QI-QP-11.21-1 will be clarified to state that standard
welding symbols as referenced in the procedure are only " typical" as
allowed by AWS 2.4-79.
Additionally, a subsequent revision of drawing
2323-S2-0910 sheet CSM-6C-I, more clearly depicts the weld location using
the dimensional / hatching method described above.

Corrective Action Taken Cont'd
Concurrently, an engineering evaluation was conducted with the following
results:
Due to the generic nature of drawing 2323-S2-0910, Sh. CSM-6C-I, Rev. 3,
the plate size (at the welds in question) can vary up to l'-6" max.
In
order to accurately communicate the welding requirements for this joint
design, the engineer utilized the weld symbol to specify the weld size and
minimum length. The typical centerline for acceptable weld spacing for
this generic application was identified separately on the sheet. This is
an acceptable industry practice which meets the intent of AWS 2.4-79.
To assure that the engineering requirements were met during installation,
as-built sketches were made of the eleven (11) supports identified in the
NRC report. An engineering evaluation of these as-builts has verified
that all eleven are in compliance with the welding requirements specified
by this typical drawing.

Criterion X of Appendix B to 10 CFR Part 50, as implemented by Section
10.0, Revision 1, dated July 31, 1984, of the TUGC0 QAP, states, in part,
"A program for inspection of activities affecting quality shall be
established and executed . . . to verify conformance with the documented
instructions, procedures, and drawings for accomplishing the activity."
Contrary to the above, the following examples from Unit 2 HVAC duct
support inspections were observed where the Bahnson inspection program
failed to identify nonconformances with the documented instructions,
procedures, and drawings:
1.
Section 9.1 in Revision 1 of Bahnson Procedure WP-TUSI-001 states,
in part, with respect to intermittent welds, " Weld increments-
shall begin and terminate within 1/8" of the ends of the joints or
length . . . ." Seven HVAC duct supports, however, inspected by
the NRC had intermittent fillet welds which did not begin or
terminate within 1/8" of the ends of the joints.
2.
Section 6.5 in Revision 5 of Bahnson Procedure QCI-CPSES-011
states, in part, with respect to welding, "The Quality
Representative shall make certain that the size, length, and
.
location of all welds conform to the requirements of QCI-CPSES-014
and DFP-TUSI-003, and to the detailed drawing . . . ."
Independent inspection identified the following conditions in
three HVAC duct supports:
a.
A 2" long, 1/4" fillet weld required by the drawing was
measured as being 1/8" for the full length,
b.
Two, 2-1/2" long,1/8" fillet welds required by the
drawing between the two lateral braces and the main
support were missing.
c.
Two,1-1/2" long,1/8" fillet welds required by the
drawing were measured as being 1-1/4" long.
3.
Section 6.6 in Revision 5 of Bahnson Procedure QCI-CPSES-011
states, in part, " Weld profiles shall meet the following
requirements:
The faces of fillet welds may be slightly convex, flat, or
slightly concave . . . Welds shall be visually examined to
determine if the following defects are evident:
...
Undercut shall not exceed 1/32" for materials thicker than
1/4"."
One support was identified in which two welds exhibited 1/16"
undercut for 50 percent of the weld lengths on members which were
1/2" thick. The support also had a 1/4" and a 3/8" weld in which
grinding of the weld produced excess convexity, resulting in an
unacceptable weld profile.

Criterion III of Appendix B to 10 CFR Part 50, as implemented by Section

documents and that deviations from such standards are controlled . . . The
design control measures shall provide for verifying or checking the
adequacy of design . . . Design changes, including field changes, shall be

original design . . . ."
Contrary to the above, verification or checking of a design change,
initiated to resolve a deviation from design documents, did not assure the
adequacy of either the design change' or the disposition of the
nonconformance report (NCR) which documented the deviation. NCR M-80-
00161, initiated on November 6, 1980, addressed the drilling through of a
" probable" template bar, a rebar, and notching another rebar. The
disposition was "Use-As-Is" and referenced DCA No. 9091. The solution in
the DCA stated that, "The condition as described is acceptable." However,
the described condition addressed just one cut bar.
-
RESPONSE TO ITEM F (445/8603-V-04)
1.
Reason for the Violation
We admit the alleged violation for the reasons that follow.
The disposition of NCR M-80-00161 addressed authorization to cut a single
layer of concrete reinforcing steel. The disposition inadvertently failed
to address the remaining conditions due to the nature of the deviations
described as follows:
The bar cut at 2-1/2" depth is authorized by DCA 9091. The bar cut at 5-
1/2" depth is a template bar requiring no authorization for its cutting.
It has no structural significance and is used only for facilitating
installation. The template bar is a construction aide which does not (and
is not required to) appear on design drawings. Therefore, the cutting of
this bar is not a nonconforming condition. The bar notched at 7" depth is
the end of the tail of a bent bar. The cutting of such bars is
generically approved by DCA 243; no additional authorization is required
and hence this is not addressed in DCA 9091.

NCR M-80-00161 was revised in April 1986 in order to reference the
information noted above.

3.
Action to Prevent Recurrence
The adequacy of nonconformance dispositions has been the issue of a site
initiated Corrective Action Request (CAR-062 dated March 4, 1986) and a
deficiency considered to be potentially reportable under the provisions of
10CFR50.55(e) (SDAR CP-86-48 dated June 16,1986).
The evaluation of these issues include,1) an assessment of the adequacy
of NCR dispositions, and 2) programmatic problems with revising NCRs.
A review of a random sample of NCRs has been conducted to determine the
safety significance of actions resulting from completed dispositions.
This review has provided a high degree of assurance of the adequacy of the
dispositions of NCRs at CPSES. To further ensure that safety concerns do
not exist, a review program encompassing technical review of all
previously closed NCRs with " void," " repair" or "use-as-is" dispositions
is planned.
,
In order to maintain a high degree of confidence that NCR dispositions
-
will not result in safety concerns, an interdiscipline review effort has
)
resulted in new corporate procedures for controlling nonconformances and
deficiencies.
4.
Date of Comoliance
The implementing procedures and the training of personnel on the new
procedures were completed December 22, 1986.

Criterion X of Appendix B to 10 CFR Part 50, as implemented by Section
10.0, Revision 1, dated July 31, 1984, of the Tugco QAP, states, in part,
"A Program for inspection of activities affecting quality shall be
established and executed . . . to verify conformance with the documented
instructions, procedures, and drawings for accomplishing the activity."
Paragraph 2.0 in Revision 0 to Tugco Procedure TNE-AB-CS-3 requires
walkdown drawings to reflect history and methodology to produce as-built
drawings.
It further requires the walkdown drawings to depict all the
necessary information required for subsequent QC verifications; i.e.,
support configuration dimensions and material sizes.
Paragraph 3.2.3 in Revision 5 to Tugco Instruction QI-QP-11.10-2A requires
the QC inspector to verify that the completed support is in accordance
with the as-built drawing.
Contrary to the above, the following conditions were identified with
respect to seven Unit 2 cable tray support drawings:
1.
Walkdown drawings neither depicted all required information nor
included correct dimensional information necessary for subsequent
~
QC verification.
RESPONSE TO ITEM G.1 (446/8602-V-14)
1.
Reason For the Violation
We admit to the alleged violation for the reasons that follow.
Review of the specific cable tray support installations noted in the
finding has indicated this condition is the result of errors in field
measurements obtained during the preparation of as-built drawings.
In one
instance (CTH-2-9774), the finding resulted from a weakness in the
inspection procedure.
2.
Corrective Action Taken
The following nonconformance reports were issued as a result of the
conditions noted in this violation:

!.
!
1.
Reason for Violation
We admit to the alleged violation for the reasons that follow.
i
With the exception of those discrepancies which pertain to supports CTH-2-
i
9774 and CTH-2-10420, the dimension verification discrepancies described
]
in this violation are the result of isolated QC Inspector errors. The
reason for the violations associated with supports CTH-2-9774 and CTH-2-
j
10420 are as follows:
1
For CTH-2-9774, the QC inspector was required by Quality Instructions to
!
verify that dimensions shown on "As-built" drawings were within the
j
tolerances specified in QI-QP-11.10-2a. QC inspection has not been
required to assure that all dimensions are included on the drawing. Since
,
i
the dimensional information referenced in the finding was not on the "As-
i
built" drawing, those dimensional verifications were not performed by the
l
QC inspector.
,
For CTH-2-10420, the inspection method used by the inspector to measure
[
the distance between the welded attachments involved measuring the
i
distance from the ing of the weld on the C-6 channel to the ing of the
weld attaching the conduit support to the embedded plate. This inspection
method was considered acceptable practice from approximately June 1985 to
l
April 1986 due to the perceived conservatism achieved (i.e., greater
separation).
However, this measuring method resulted in the plus side of
I
the 1" tolerance allowed by QI-QP-11.10-2a being exceeded on CTH-2-1042-
'
when measured from the f_ ara of the attached member to the f_tra of the
other welded attachment.

2.
Corrective Action Taken
!
Nonconformance Reports were initiated to address the dimensional
discrepancies.
The dispositions required the drawings to be revised to
'
,
show the "As-built" conditions with the exception of the following NCRs:
l
0
NCR M-86-201794 addressing CTH-2-9774 was dispositioned "Use-as-
is."
The disposition does not require the location of the
3/8"x4"x5" plate with respect to the C-6 channel to be on the
drawing, only that the weld requirement of the plate to channel is
per design drawing. This weld dimensional requirement was
,
verified by QC at the time of the original QC inspection.
O
Also, per the NCR disposition, DCA 24400 was issued April 2, 1986,
to provide verification criteria when the dimensional location of
,
the tray clamp in relation to the C-6 channel is not shown on the
l
drawing. QI-QP-11.10-2A has been revised to include this
criteria.
l-
0
NCR M-86-202657 was initiated to address the previous use of the
toe-to-toe method to measure the separation distance between
]
welded attachments to embedded plates. CTH-2-10420 is addressed
in the NCR since it was inspected using this method.
Further
!
action will be taken as required by the NCR disposition.
Subsequent clarification was received by Engineering whereby the
,
j
separation measurements were to be verified using face-to-face,
)
unless otherwise detailed on the design drawing. The clarified
method for measuring has been applied since April 1986.

3.
Action to Prevent Recurrence
i
!
Each of the QC Inspectors involved with acceptance of the discrepant
installations identified have been made aware of their errors. To
i
determine the need for further corrective action, the performance of these
j
inspectors was evaluated through review of Quality Surveillance
reinspection results.
Based on this review it has been determined that
i
the involved inspectors have demonstrated a high degree of accuracy in the
!
performance of inspections and no further corrective action is needed.
l
Per the disposition of NCR N-86-201794, no further action is required for
!
the dimensional 3/8"x4"x5" plate-to-channel finding. However, the
revision of QI-QP-11.10-2a should prevent recurrence of the erroneous
j
dimensional location of the tray clamp plate-to-the channel finding.
The clarification of attachment separation inspection methods used should
l
prevent recurrence of this finding.

Full compliance has been achieved.
Part 2
" ... site procedures do not clearly describe the conditions under which a

1.
Reason for the Violation
.
At the time of inspection, procedures failed to clearly describe the
conditions for initiating a DR or NCR.
2.
Corrective Action Taken
Recently issued Nuclear Engineering and Operations (NE0) procedures
clearly define the site guidelines for deficiency and nonconformance
reporting.
Implementing procedures will be revised to include
requirements of the appropriate NE0 procedures.
3.
Action to Prevent Recurrence
The corrective action should prevent recurrence of this part of the
Violation.
4.
Date of Compliance
The procedures will be revised by January 15, 1987.
Part 3
" ... nor were DRs reviewed for potential conditions requiring an NCR prior
to a June 1985 revision to the deficiency reporting procedure STA-404."
1.
Reason for the Violation
All prior revisions of STA-404, " Control of Deficiencies", have required
Quality Assurance to determine if the deficiency "may cause or has caused
a nonconformance." This part of the violation occurred because STA-404
did not require clear documentation of the review for noncoriforming
conditions.

RESPONSE TO ITEM A (445/8603-D-14)
1.
Reason For Deviation
!
{
We admit to the alleged deviation for the reasons that follow,
i
!
The primary reasons for the deviation are imprecise guidance in QI-019 and
j
inspector misinterpretation of that guidance.
Prior to Revision 3, QI-019
did not specifically address allowable clearances in the gravity direction
.
!
for dead weight, box frame supports. Although these clearance
requirements were covered in ERC Inspector training, some confusion
!
existed over eleven inspection packages in which the box frame support
i
drawings showed the pipe in contact with the support but specified no
!
allowable clearance value.
ERC decided to revise QI-019 to reflect
I
clearance requirements as taught in inspector training, and to reinspect
!
those eleven packages. As a result, ERC Description Memorandum QA/QC-RT-
1436 (dated 2/10/86) was issued to describe the Revision 3 changes to
section 5.3.5(A) of QI-019.
(The memo erroneously stated that no
previously issued packages were affected by the changes, when in fact
Attachment A to the memo listed the eleven (11) packages requiring
!
l
reinspection. Recognizing the error in the memo, ERC issued Revision 1 to
,
!
QA/QC-RT-1436 the same day, stating that the change to QI-019 did affect
the eleven (11) previously issued packages.)

1.
Reason for Deviation (cont'd)
Subsequent to the issuance of QA/QC-RT-1436, listing the eleven (11)
packages to be reinspected, ERC became aware of past inspector confusion
over allowable clearances even when zero inches (0") clearance in the
gravity direction was specified on the drawing.
ERC then issued
Supplemental Inspection Instructions requiring reinspection of all box
frame, dead weight supports in the small bore population.
In total, 32
packages were reinspected resulting in 9 Deviation Reports regarding zero
l
clearance in the gravity direction.
Package No. I-S-SBPS-051 was among
those reinspected, and a clearance violation in the gravity direction was
noted on Deviation Report No. I-S-SBPS-051-DR3 and subsequently on NCR M-
23400N R-1. Attachment A to memo QA/QC-RT-1436 was not revised to reflect
i
these reinspections.
2.
Corrective Action Taken
Corrective Action has been completed with the issuance of Rev. 3 to QI-019
and with the reinspection of all affected packages as of May 30, 1986.
~
Revision 2 to QA/QC-RT-1436 was issued on November 11, 1986, and contains
a note referring to the reissuance of all affected packages.
3.
Action to Prevent Recurrence
No action to prevent recurrence is contemplated for the Small Bore
population as reinspection efforts are complete and Rev. 3 to QI-019 has
been issued. As a result of CAR-16, ERC QI procedures were reviewed in
meetings between engineers and inspectors to ensure clarity and
consistency of the procedures. The need to clarify box frame support
clearance criteria in QI-019 was identified in a January 11, 1986, CAR-16
meeting.

l
The ERC QA/QC Discipline Engineer did in fact review QI-QAP-11.1-28
Revision 3) for applicability in developing the QI-029 inspection
checklist.
Inspection for excessive grinding due to welding defects on
i
base materials was not included on the checklist for the following
i
reasons. While excessive grinding may be readily detected after initial
i
installation is complete, it cannot be accuratelv reinspected following
i
application of coatings.
In most cases, the grinding performed to remove
1
weld defects would not be detectable through paint at all.
Further, while
!
the ASME Code Subsection NF stipulates that grinding to remove weld
defects may not encroach on minimum base metal thickness, there is no code
'
requirement to inspect for other types of defects in base metal as a
!
result of the welding process. Once coatings have been applied, it is
l
difficult to distinguish between markings due to grinding versus other
i
potential causes.
Paint removal to inspect for potential excess grinding
i
is impractical.
In addition, paint removal methods also remove some base
metal in the process, making an accurate determination of the depression
j
depth impossible.
For these reasons, the ERC QA/QC discipline

engineer concluded that inspection for excessive grinding of base metal
through paint is not a recreatable characteristic of the welding
attribute.
In accordance with ISAP VII.c, attributes or subattributes
which are deemed not recreatable are not included on inspection
checklists.
However, due to NRC inspector concerns, the ERC inspector wrote an Out-of-
Scope observation for Verification Package No. I-S-LBSN-065 noting
potential excess grinding on the pipe support base metal. A
Nonconformance Report was subsequently issued and is currently being
evaluated to disposition the Out-of-Scope observation.
It should also be noted that the nominal flange thickness for this pipe
support (a W4 x 13 structural shape) is 3/8 inch.
In accordance with QI-
QAP-11.1-28, a depression depth of 1/16 inch (the observed condition) is
.
thus acceptable.

ITEM C (445/8603-D-17)
C.
Section 5.2 of ERC Procedure CPP-022, Revision 0, states, in part, " Paint
shall be removed from the weld connections which have been inspected
through paint . . . . Results of these visual inspections shall be
documented and include, as a minimum, criteria utilized, (and) any
discrepancies." Section 5.2.D of ERC QI-062, Revision 0, states, " Verify
surface of welds are sufficiently free of overlap, abrupt ridges and
ripples so proper interpretation of radiographic and/or other required NDE
could be accomplished."
In deviation from the above, ERC quality inspection documented in
Verification Package No. I-S-NPBW-014 that the surface of welding which
attached item 1 to support steel identified on Drawing FW-1-019-901A-C57W
was acceptable.
Independent inspection identified, however, that after
removal of coatings the weld surface was unacceptable.
Subsequent to the
NRC inspection, ERC personnel issued a deficiency report documenting the
rejectable weld condition.
RESPONSE TO ITEM C (445/8603-D-17)
We deny the alleged deviation for the reasons that follow.
> -
The surface of the subject weld (with paint on) was inspected per packages
I-S-PWRE-006 and I-S-NPBW-014. Weld surface irregularities were noted by
the inspectors and the attribute rejected in each package. The rejection
was documented on DR No. I-S-PWRE-006 DR2.
(No DR was written for the
NPBW package, as the second part of the inspection called for weld surface
examination with the paint removed.)
Following paint removal, the weld surface could be more easily examined.
The weld surface attribute was accepted in I-S-NPBW-014 and later in
Overview Inspection Report No.24-008 (I-S-PWRE-006). Due to NRC concerns
about the weld surface, however, an independent Level III inspector was
brought to CPSES to examine the weld. The report by this Level III
inspector stated, "This writer found this weld to be acceptable except in
some cases where abrupt ridges and valleys were pronounced due in part to
limited grinding of the surface.
It should be noted that this is a
judgement interpretation that would vary from weld to weld and in some
cases the final magnetic particle test may require additional surface
preparation influenced by the specific MT method used." The independent
Level III inspector concluded: "It is evident that the magnetic particle
examination would be the last determining factor as to the adequacy of the
weld."
A review of the original magnetic particle examination of the weld
performed by Chicago Bridge and Iron indicated the acceptability of the
weld and weld surface. Based on the judgement of the ERC inspectors, the
independent Level III inspector report, and the acceptance of the weld in
the original NDE report, ERC concluded the weld surface was acceptable.
However, due to continuing NRC concerns regarding the interpretation of
the independent Level III inspector's report, Deviation Report No. I-S-
NPBW-014 DR1 was generated.

RESPONSE TO ITEM C (445/8603-D-17) CONT'D
To resolve the issues, a Brown and Root Level III inspector performed a
Magnetic Partical Test on the weld. On the basis of the test report
(MT/PT Report #29023) the weld and weld surface were acceptable.
Therefore, no deviation exists. DRs No. I-S-NPBW-014 DRI and No. I-S-
'
PWRE-006 DR2 will be invalidated.

D.
Section 5.1.1 of Revision 2 to ERC Procedure CPP-008 states, in part,
. . . should an attribute appear on the generic checklist and not be
"
applicable to the specific item, the engineer indicates 'N/A' and provides
reasonable justification for the entry."
In deviation from the above, an independent inspection of Verification
Package No. I-S-HVDS-075, support DG-844-2K-1J, revealed that Sections
2F.1, ?F.2, and 2F.3 in the checklist for QI-035, dealing with embed
plates and spacing violations, had been "N/A'd" by the engineer.
Further, the noted justification for this entry was "No Embedded PLs."
However, independent inspection identified the existence of an embed plate
with dimensions of approximately 20' X 8".
RESPONSE TO ITEM D (446/8602-D-13)
We deny the alleged deviation for the reasons that follow.
Sections 2F.1, 2F.2, and 2F.3 for Verification Package No. I-S-HVDS-075
had been "N/A'd" by the ERC engineer. The justification for this entry
was "No Embedded PLs". A subsequent review of this package by ERC has
,~
!
revealed that a deviation does not exist. The ERC Engineer correctly
N/A'd these attributes.
Quality Instruction (QI) 035, " Reinspection of HVAC Duct Supports"
delineates the inspection requirements to be performed for this population
(HVDS).
Section 5.2.2F of this QI addresses Welded Attachments to
Embedded Plates.
For the 2F. attributes to be inspected, the duct support
has to be attached (welded) to the embedded plates. Verification Package
No. I-S-HVDS-075 contains support DG-844-2K-lJ for inspection.
Support
DG-844-2K-1J is not welded to an embed plate, therefore these attributes
(2F.1, 2F.2, and 2F.3) cannot be reinspected. Therefore, the ERC engineer
correctly N/A'd these inspection attributes.
During the course of this review and subsequent discussions with the NRC
it was brought to the attention of ERC that NRC had a concern with
Attribute 4C.3, "Hilti to Embedded Plate Edges". The ERC inspector had
originally accepted this attribute. QI-035, Section 4C.3 requires the ERC
inspector to " verify that the minimum distance of each Hilti anchor to any
adjacent embedded plate (or Nelson stud, if available) meets the
requirements of Attachment 6.17..."
The required minimum for a 1-inch
Hilti to the edge of an embedded plate is 7-1/2 inches.
Subsequent
inspection of attribute 4C.3 revealed a 1 inch Hilti installation 7/8-inch
from an embedded plate.
Verification Package No. I-S-HVDS-075, was reissued and a deviation report
I-S-HVDS-075-DR4 issued by the ERC inspector on July 31, 1986, identifying
,
the discrepant condition.
In addition, Nonconformance Report No. M-86-
202172X was issued on September 2, 1986 and has not yet been
dispositioned.

on the drawing. The member whose lengths were not shown, spanned two
l
members. These members were verified, under the configuration attribute,
to ensure that they spanned the two members. However, a tolerance was not

applied to the member length, because it was not considered safety
significant.
Therefore, attribute 2D. was accepted for the aforementioned members. The
acceptance was based on engineering judgement that the member length

RESPONSE TO ITEM E.2 (446/8602-D-11) CONT'D
1.
Reason for Deviation (cont'd)
Subsequent discussions with the ERC inspector revealed that a six inch
rule had also been used to verify the skewed weld leg size. The six inch
rule was used to measure the leg that had the member "end prepped." The
inspector apparently accepted the attribute on that basis. Based on
further discussions with the ERC inspector, NRC inspector, and TUGC0 QA/QC
personnel it was determined that the ERC Level III should verify attribute
38. The Level III inspector successfully measured one leg of the skewed
fillet weld using a skewed weld gage. The Level III inspector determined
that the second leg of the weld could not be measured in the manner
demonstrated by the ERC inspector. The measured leg size was 3/8-inch.
Measurement of the second leg was found to be indeterminate. Therefore, a
deviation does exist for Verification Package No. I-S-HVDS-075 attribute
38.

Gentlemen:
,,
In a conversation with your Mr. I. Barnes on March 12, 1987, we advised
Region IV that the date for completion of the corrective action regarding
Notice of Deviation Response to Item E.2 446/8602-D-11 was being revised.
Specifically, the date of full compliance stated in the response was
February 20, 1987. DR I-S-HVDS-075-DR5 was not resolved until March 11,
1987. The date of full compliance, therefore, was achieved on March 11,
1987.
