Surveillance Testing and Calibration Activities
2.1 Administrative Controls
Administrative controls were reviewed to evaluate the#11censee's
program for implementing requirements associated with surveillance
. testing and calibration activities. .The objectives were to assure
that the ' licensee programs in place were consistent with the Tech-
nical. Specifications, Regulatory Guide 1.33, ANSI N18.7 and Appendix
B of 10 CFR 50. Calvert Cliffs Instruction (CCI)-104H delineates how
the conduct of the surveillance / calibration program is accomplished,
however, several other supporting CCIs are utilized in conjunction
with CCI-104H. Attachment I lists these CCIs and other documents
that were reviewed throughout the inspection.
2.2 Organization
In January 1986, a restructuring of the plant organization resulted
in a change to the manner in which surveillances/ calibrations are
scheduled, reviewed, tracked, etc. Prior to this reorganization,
surveillances were essentially planned, scheduled, tracked, reviewed,
and trended by one designated individual for each discipline,
i.e.,
operations, mechanical, electrical and controls.
Engineering in-
volvement came into play usually upon "out-of-spec" conditions.
However, engineering personnel have since been relocated from the
corporate office to the plant site and are now more actively involved
in the review process of completed surveillance test procedures
(STPs).

.
Organizational 1y, the General Supervisor-Plant and Project Engineer-
ing has overall responsibility for the administration of the sur-
veillance test program. .Eight positions have been established to
provide the needed controls and are as follows:
i
Engineering Surveillance Test Coordinator
Electrical & Controls Surveillance Coordinator
Mechanical Maintenance Surveillance Coordinator
Fire Protection Surveillance Coordinator
.
Inservice Inspection Surveillance Coordinator
Operations Surveillance Coordinator
Electrical & Controls Scheduling Coordinator
Mechanical Maintenance Scheduling Coordinator
Presently, inservice inspection surveillance responsibilities are
being handled by the Operations Surveillance Coordinator.
2.3 Review / Implementation
The inspector held various discussions with department managers,
group supervisors, surveillance coordinators, and scheduling
coordinators to ascertain the extent of their responsibilities in
reference to surveillance and calibration testing. These
discussions included a review of the following:
Master surveillance schedule
Monthly surveillance test schedules
Seven day working schedules
Various STP's used during the performance of
=
surveillances/ calibrations.
The licensee has created a Planning and Scheduling Group, of which,
the E&C Scheduling Coordinators (E&C SC) and Mechanical Maintenance
Scheduling Coordinators (MMSC) are part, They plan and schedule
surveillances, calibrations, and preventive and corrective main-
tenance activities for their respective disciplines. They are not,
however, involved in the review process of completed surveillances.
These are forwarded to a system engineer, via the Engineering Sur-
veillance Test Coordinator, following a supervisory review. The MMSC
and E&C SC are informed of the completion of the scheduled surveil-
lance through the use of a "PM/STP Feedback Sheet" which is attached
to each STP.
The Maintenance Supervisor, or designee, completes the
Feedback Sheet and forwards it to the appropriate Scheduling Coordin-
.
l
ator. The MMSC or E&C SC utilizes this sheet to schedule the next
performance of the STP.

No instances of missed surveillances were identified. - However, upon
further review of this process, the inspector determined that the
"PM/STP Feedback Sheet" was not being effectively used as _ intended.
Only_on certain occasions were the Scheduling Coordinators reviewing-
this feedback sheet.
In most instances, they were being informed of
completed surveillances verbally during_ departmental meetings held
frequently throughout the week.
The inspector noted that this: feedback mechanism.is_an essential
part of the licensee's program in assuring that surveil. lances are
. performed within the required frequency, especially'since the
scheduling coordinators are not involved in the review process. The
licensee acknowledged the inspector's concern and stated.that
CCI-104H was just recently issued and needed additional attention.
The inspector had no further questions regarding this concern.
The inspector verified that calibration methods and associated fre-
quencies had been established for installed instrumentation utilized
during the performance of technical specification-required surveil-
_
lances. These instrument calibrations are tracked, scheduled and
_
performed under the preventive maintenance (PM) program. The in-
spector selected four surveillance requirements associated with the
1) auxiliary feedwater, 2) containment cooling, 3) emqygency core
cooling, and 4) condensate systems.
From these survey 11ance require-
ments, the licensee was requested to provide-the appropriate PM
identifier which documented the calibration of associated instrumen-
tation used during the performance of these surveillances.
Sub-
sequently, the inspector retrieved from' plant history, the appro-
priate PM cards (copies) which are utilized to document the
performance of PM calibrations. No discrepancies were. identified.
Discussions were also held with the onsite Licensing Group, since
they are responsible for identifying the need to create or revise an
STP as a result of a license amendment.
The inspector selected from
the Master Status Log of T.S. Changes, Facility Change Request
83-1013 "125 Volt DC System." The FCR package was retrieved from
plant history and the inspector reviewed the package and those steps
taken to ensure that changes to STP-M-550-0 were made as a result of
the licensee amendment. Before the licensing group closes a FCR,
they ensure that appropriate changes have been made to STPs and that
these changes have been implemented as well.
The inspector also observed the performance of STP-M-310-1, " Linear
Power Channel Calibration" conducted on the morning of August 21,
1986. NRC observation of this surveillance was to verify that the
following was accomplished.
Applicable STP was approved, up-to-date, and utilized
throughout the conduct of the surveillance.

.
Appropriate personnel were notified prior to the start of the
test.
Calibrated test equipment was used.
Acceptance criteria were met, and if not, appropriate steps
were taken.
Following completion or postponement of the test, system was
realigned for normal operation.
During the calibration of channel A, subchannel B, meter NI-005
indication was found to be out-of-tolerance at the 200% power test
level. The E&C technicians immediately informed the shift
supervisor, stopped any further testing, and realigned channel A to
its normal configuration.
Subsequently, Maintenance Order No.
206-233-411A was generated to allow for necessary adjustments to
bring NI-005 within tolerance limits. Quality Control was present
during the readjustment and re-calibration check of NI-005.
2.4 Findings
As the E&C technicians were setting up to perform STP-M-310-1, the
inspector observed that potentiometers S/N 10980 and 11237, had
exceeded their re-calibration due dates. The inspector pointed this
out to the E&C technician, who stated that these test instruments
were being utilized only as a power supply, and that digital volt
meters (DVM) S/N 448297 and 835509 were the critical standards to be
utilized during the test (These DVMs were found to be within their
re-calibration due date.).
The inspector accompanied the technician to the E&C shop test in-
strument storage cage, whereupon an attempt was made by the-licensee
to find two similar potentiometers that had been calibrated. None
could be found, however five more potentiometers, all of which had
exceeded their re-calibration due dates, were found in their normal
storage locations. Heise gauge, No. 17476 was also found in its
normal storage location and it too had exceeded its' re-calibration
due date.
Licensee Quality Assurance Procedure -17 " Control and
Calibration of Measuring and Test Equipment" requires that test
instruments be appropriately identified as to their out-of-calibration
status and physically separated from the rest of the test equipment.
This is a violation (317/86-15-01; 318/86-15-01).
The inspector held further discussions with the licensee, regarding
whether proper controls were in place for the storage and issuance of
test equipment, and why the E&C technicians inadvertently picked up
the two "out-of-cal" potentiometers in the first place. A subsequent
review of a previously conducted audit by the licensee's onsite QA
organization and the above mentioned violation indicates that manage-
.
6
,
ment involvement and evaluation of the storage and issuance of test
equipment is warranted.
3.0 QA/QC Interface
l
The inspector held discussions with both QA and QC supervision to deter-
mine their involvement with the surveillance testing and calibration
program. QC receives monthly,-a schedule of those surveillances planned
for the upcoming month. Their review of this schedule and appropriate
surveillance test procedures enables them the opportunity to decide what
STPs they would like to witness. QC also observes all adjustments, re-
tests, etc.,
for those surveillance tests in which problems had ini-
tially occurred.
The inspector also reviewed the most recently completed audits conducted
,
by QA of the surveillance / calibration and measuring and test equipment
areas. Findings were noted in the surveillance testing area, however they
were minor in nature and were resolved prior to the completion of the
audit. Several findings were identified in an audit of the measuring and
test equipment area conducted in April 1986. Audit findings have since
been resolved, however it appears, based on the inspector's findings, that
corrective measures need further strengthening in this area.
