Licensee Action on Previous Enforcement Matters (92702)
(Closed) Violation 348/85-22-01, Failure to Follow ISI Plan. Alabama Power Company's letter of response dated June 5,1985, has been reviewed and determined to be acceptable by RII.
Based on examination of corrective actions as stated in the letter of response and discussions with responsible licensee personnel, the inspector concluded that Alabama Power Company had determined the full extent of the subject violation, performed the necessary survey and followup actions to correct the present conditions, and developed the necessary actions to preclude recurrence of similar circumstances. The inspector reviewed the following to verify implementation of corrective actions:
'
-
Corrective Action Report (CAR) No. 997
'
-
FNP-1-STP-157.0, Revision 2, Inservice Inspection of Class 1 and 2 Systems and Components
-
FNP-2-STP-157.0, Revision 2, Inservice Inspection of Class 1 and 2 Systems and Components 4.
Unresolved Items (92701)
Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or deviations.
One new unresolved item identified during this inspection is discussed in paragraph 5.a.(4).
5.
Maintenance Welding and Nondestructive Examination (NDE) (Units 1 and 2)
The inspector examined the welding and NDE activities described below to determine whether applicable regulatory and code requirements were being met.
In general, the governing code is ASME Section XI,1974 Edition, S75 Addenda.
For maintenance welding and NDE of ASME Code Classes 1, 2, and 3 piping and components, the codes listed below apply as implemented by Alabama Power Company (APCO) Nuclear Generation Welding Manual (FNP-0-M-023)
and NDE Program Manual (FNP-0-M-024).
These manuals are evoked by site procedure FNP-0-AP-12, Revision 4.

a.
Nuclear Welding (55050)
The inspector examined the following activities relative to the welding maintenance program:
(1) Welding Program - General The inspector reviewed the welding program in general as defined by the following:
FNP-0-AP-12, Revision 4, " Control of Special Processes During
-
Operations" FNP-0-M-23, Nuclear Generation Welding Program Manual
-
During this review, the inspector noted several areas of weak-ness, i.e., areas where the program did not contain sufficient detail. Examples were:
i
-
Lack of guidance relative to in-process inspections - fitup, welding procedure requirements, final weld size, etc.
Insufficient details on material storage and issue
-
-
Lack of requirements for detailed weld joint record Insufficient details on maintaining status of welder qualification
-
The licensee pointed out that a new Special Processes Manual, in preparation and scheduled for issuance in September 1985, would provide much more detail and would strengthen weak areas in the welding program.
The inspector briefly reviewed a draft of the new manual, and it appears that the manual will greatly improve the welding program.
Pending review of the new manual after final issuance, Inspector Followup Item 348, 364/85-33-01, Review of Special Processes Manual, is opened.
(2) Welding Material Control The applicable procedures for welding material control are:
-
FNP-0-AP-12 FNP-0-AP-9, Revision 10
" Procurement and Procurenent
-
Document Control FNP-0-M-23, WP-011, Revision 1, " Welding Procedure for ASME
-
Section III" i

.
Relative to welding material control, the inspector verified that the licensee had established procedures for purchasing,
-
receiving, storing, disbursing and handling of welding materials welding material storage procedures contained requirements
-
for environmental (moisture) control procedures contain effective measures for limiting moisture
-
pickup and maintaining identification after issue to the welder
-
welding material control system meets requirements for the most restrictive application (3) Welding procedures The inspector verified that the licensee had established procedures for preparation, qualification, approval, certification and issue of welding procedure specifications.
The applicable procedures are:
FNP-0-M-23 including WP-011
-
FNP-0-AP-1, Revision 16 " Development, Review and Approval of
-
Plant Procedures" (4) Welder Performance Qualification
The inspector _ verified that the licensee had established procedures for qualification of welders.
The applicable
'
procedures are:
-
FNP-0-M-23, WP-011 FNP-0-M-23, WP-030, Revision 1,
" Welder Qualification
-
Procedure" FNP-0-AP-12
-
The inspector reviewed original qualification records and qualifiction status records for welders F-5, F-9, F-10, and F-12 who performed welding on the welds listed in paragraph (5) below.
The inspector noted that the method being used to track welder qualification status, the " Performance Qualification Renewal" form, precludes verification that welders maintain their qualifi-cation by welding with each, process every three months as required by ASME Section IX. Actual welding dates are not being entered on the fom; the fonn indicates that the welder welded some time within a calendar quarter, e.g., 07/01/85 - 09/30/85.

'
'
discussion of this problem with the licensee, it was also detennined that the form is being filled out prior to start of the
'
quarter based on the welder having welded the previous quarter.
Using this system, it is impossible to determine if the welder
used each process every three months.
In addition, the makeup of I
the form indicates that the Maintenance Supervisor, who signs as the " Responsible Supervisor", witnesses the welding. Discussions
'
revealed that he does not actually witness the welding.
It was
also noted that the Maintenance Supervisors' signature was not
. dated.
Due to the questions relative to maintenance of welder
<
qualification status, the licensee agreed to review past mainte-nance welding records and determine if welders have welded production welds with expired qualifications.
Pending evaluation
.
I of the licensee's review, this matter is considered unresolved and.
!
is identified as Unresolved Item 348, 364/85-33-02, Welder l
Qualification Status Records.
(5) Production Welding In lieu of observation of welding, the inspector reviewed weld
.
records consisting of " Weld Process Control Sheets" for the following Unit 1 Welds:

During review of the records, the inspector noted the following
'
t problems:
!
(a) The Process Control Sheets did not indicate any in-process quality inspections such as.fitup, compliance with procedure i
l requirements, final weld size, etc. The only inspection was
a final NDE inspection for each weld. The licensee indicated l
that in accordance with their program, as defined in plant procedure FNP-0-AP-31 Revision 7, -" Quality Control Measures", the welders and welding foremen are responsible for the quality of the weld -and are qualified as level II inspectors to ANSI Standard N45.2.6.

4 inspections are specified on the Process Sheet, no
inspections other than the welder's and foreman's is required.
If an independent inspection is specified on the Process Sheet, the responsible group supervisor for the work
activity being inspected shall assign a qualified inspector
to perform the required inspection.
The independent inspector may be another maintenance journeyman or foreman who is qualified to procedure FNP-0-AP-31 and is independent
!
.
of the work actually being inspected.
However, as noted no
'
independent in-process inspections were specified or performed for the above welds.
Paragraph NA-4133.10 of ASME Section III, the applicable code for the above welding, requires that in-process inspections to assure conformance with instructions and procedures be
>
performed and that the inspections be performed by persons other than those who performed the activity being examined.
In addition, such persons are not to report directly to the
'
imediate supervisors who are responsible for the work being
,
inspected.
!
10 CFR 50, Appendix B, Criteria X, requires that a program for inspection of activities affecting quality be established and that such inspections be perfonned by individuals other
than those who performed the activity being inspected.
Paragraph 17.2.10 of the Farley FSAR, which implements l.
Appendix B, Criterion X, states that maintenance activity inspections will include the original inspection requirements
<
to the extent the original requirements can be determined
from available documents.
The welds in question originally received in-process inspections such as fitup, final visual, procedure compliance, etc.
This failure to perform in-process inspections by independent
,
i inspection personnel for the above listed welds is in -
'
violation of 10 CFR 50, Appendix B, Criterion X, and ASME
-
'
Section III and is identified as Violation 348/85-33-04,
'
Failure to Perform Independent In-process Inspections for Class 1 and 2 Pipe Welds.
(b) As noted above, procedure FNP-0-AP-31, which implements ANSI Standard N45.2.6 and Regulatory Guide (RG) 1.58,. allows welders and foremen to be qualified as Level II inspectors and perform welding inspections.
Position 3 of RG 1.58 j
requires that specific technical abilities of the person being certified should be related to the specific assigned
,
task.

Inspector certification records for one foreman and one welder were reviewed and the following areas that appear to violate RG 1.58 and ANSI Standard N45.2.6 were identified:
The " Basis for. Certification" by the Farley program is l
' -
education and experience. - For the records reviewed, it is impossible to determine if the documented experience is related to the specific assigned task (welding, i
electrical,etc.)
,
Maintenance journeymen and' f oremen are certified as
-
level II inspectors in the general area of " Maintenance,
'
' Activities" regardless of the maintenance area to be
inspected.
This general activity classification is-too
'
broad to assure that inspectors are qualified as related
,
'to specific assigned task (welding, electrical, etc.).
,
i During discussion of this matter with site QA personnel, the inspector found that the licensee had an open QA audit
finding (see. QA Audit Finding FNP-NC-43-85-8(17)) almost identical' to that identified above.
At the time of the l
current inspection, the audit' finding was still being l
evaluated.
Pending review of the licensee's corrective
'
-
action to the QA audit, this matter is identified as

Period 2, Outage 1 4-6 and 4-17 APR-2-2110
Period 2, Outage 1 4 and 52 APR-2-2314 The records were reviewed in the areas of:
Calibration data sheets
-
-
Proper recording of recordable indications Evaluation of examination data by Level II or Level III examiner
-
Evaluation of data complies with applicable procedures
-
Evaluation of indications complies with applicable procedures
-
c.
During review of the above records, the inspector reviewed the licensce's program for inspection of pipe supports required to be inspected by ASME Section XI.
Inspection data for Unit I spring type hangers, inspected during the last outage (period 3, Outage 1), were reviewed.
The inspector found that for Unit I spring hangers
"A" on 150 ALA-221 and "F" on ISO ALA-218, the support settings were not verified as required by ASME Section XI, Table IWC-2520.
Paragraph 3.6.1 of Procedure ISI 8, revision 07, Am. 01, " Visual Examination Procedure",
requires that hangers having calibrated load indicators have the scale reading recorded.
Paragraph 4.10 of FNP-1-STP-157.0, Revision 1,
" Inservice Inspection of Class 1 and 2 Systems and Components",
requires that support settings of constant and variable spring type hangers be verified.
This failure to verify support setting is in violation of 10 CFR 50, Appendix B, Criterion V, and is identified as Violation 348/85-33-05, Failure to' Follow Procedures for Verification of Spring Support Settings.
,The inspector noted that although the licensee's procedures and QA program had been violated, the ASME Code had not been violated at the-time the violation was found.
ASME Section XI requires that the supports in question be inspected during the third 40 month period. Since or.ly th'e 1st outage of the period has passed, the settings can be verified during a future outage prior to expiration of the period. However, it is not certain that the licensee would have caught the omission had the inspector not reviewed the records.
"
Within the areas inspected, one violation was identified. No deviations were identified.
