' Followup On Previously Identified NRC Items
.
-(Closed) Violation (482/8530-03): Flow Orifice Installed Backwards
The NRC inspectors verified-that Orifice Plates EG FE-64, 83, and 89 were
reversed and installed properly.
In addition, the NRC inspectors verified
that maintenance personnel have been trained on the proper orientation of
f
orifice plates, that maintenance engineers have been trained to specify
y
proper orientation and that quality engineers have been instructed to
23
verify that work instructions provide for proper orientation.
This
'
violation is' closed.

'
(Closed) Open Item (482/8621-03):
Licensed Operator Requalification Exam
.
Regrade
This item tracked the licensee's commitment to regrade all exams taken in
the 1986 requalification exam to insure correct grading.
The licensee has
performed this task. This open item is closed.
4.
Operational Safety-Verification
The NRC inspectors verified that the facility is being operated safely and
in conformance with regulatory requirements by direct observation of
'
licensee facilities, tours of the facility, interviews and discussions with
licensee personnel, independent verification of safety system status and
limiting conditions for operations, and reviewing facility records.
The
NRC inspectors, by observation of randomly selected activities and interview
of personnel verified that physical security, radiation protection, and
fire protection activities were controlled.
By observing accessible components for correct valve position and
electrical breaker position, and by observing control room indication, the

NRC inspectors confirmed the operability of the high pressure coolant
injection (charging) system. The NRC inspectors also visually inspected
safety components for leakage, physical damage, and other impairments that
could prevent them from performing their designed functions.
5.
Monthly Surveillance Observation
.
The NRC inspectors observed selected portions of the performance of
surveillance testing and/or reviewed completed surveillance test procedures
to verify that surveillance activities were performed in accordance with TS
requirements and administrative procedures. The NRC inspectors considered
the following elements while inspecting surveillance activities:
Testing was being accomplished by qualified personnel in accordance
.
with an approved procedure.
,
The surveillance procedure conformed to TS requirements.
.
Required test instrumentation was calibrated.
.
Technical Specification limiting conditions f<
operation (LCO) were
.
satisfied.
Test data was accurate and complete.
Where appropriate, the NRC
.
inspectors performed independent calculations of selected test data to
verify their accuracy.
The performance of the surveillance procedure conformed to applicable
.
administrative procedures.
The surveillance was performed within the required frequency and the
.
test results rnet the required limits.
Surveillances witnessed and/or reviewed by the NRC inspectors are listed
below:

y
During'a review of randomly selected surveillance procedures that had been

completed and transmitted to the records vault; the NRC inspector observed
.
that Steps 6.3, 6.4,'and 6.5 of Surveillance Procedure STS MT-016,
-
n
,,
Revision 3, " Standby Diesel Generator Inspection," had not been signed, as
required.
In_ addition Section 5.6.2 of Administrative procedure ADM
02-300, " Surveillance Testing," states that, "Each reviewer of test
3'
results shall ensure that each test package is complete including all test
data / signatures required by the subject test." This failure of designated
-pe.rsonnel (test performer, supervisor, and QC supervisor / lead) to sign the
g
required procedure steps and of the reviewers to identify and ccrrect the
-
- oversight, as required by the above procedures is an apparent violation
'
(482/8628-01).
The NRC inspector did not identify any other
3
discrepancies during this review.

6.
Monthly Maintenance Observation
'
The-NRC inspector observed maintenance activities performed on
safety-related systems and components to' verify that these activities were
conducted in accordance with approved procedures, Technical Specifications,
and applicable industry codes and standards.
The following elements were
considered by the NRC inspector during the observation and/or review of
the maintenance activities:
LCOs were met and, where applicable, redundant components were
'
.
-
' operable.
Activities complied with adequate administrative controls.
..
Where required, adequate, approved, and up-to-date procedures were
.
used.
Craftsmen were qualified to accomplish the designated task and
.
technical expertise (i.e., engineering, health physics, operations)
m
was made available when appropriate.
Replacement parts and materials being used were properly certified.
.
Required radiological controls were implemented.
.
Fire prevention controls were implemented where appropriate.

determined that a sealed source had not been tested as required every six
d
months.
This event was caused when licensee personnel, who incorrectly
-3
categorized this source as being "i.fstorage" and removed it from the list
-3
of sources requiring a leak test every six months.
Licensee personnel put
.the source back on the list when the error was identified and verified
5
through records that all other sources had been tested, as required, and
j
also made it a requirement that.the site health physicist had to approve
j
removal of any test sources from the list.
f
The second event occurred on April 22, 1986, when an incore neutron
detector was installed prior to being tested as required by the TS. The
licensee placed tags on the storage cabinet for the fission detector
h
instructing warehouse personnel to contact reactor engineering and health
?
physics prior to. issuing the detectors.
This LER and the related Defect
J
Deficiency Report (DDR)86-043 were provided as required reading for
G
cognizant personnel.
The NRC inspector reviewed the required reading

On September 23, 1986, licensee personnel determined durir.g performance of
7

a routine surveillance that the spent fuel crane overload limit was set
s
200 pounds greater than the TS (3.9.7) specified 2250 pounds.
Contrary to

the TS, new fuel was moved between September 23 and 25, 1986, with the

crane overload limit set wrong.
Discussion with the licensee determined
1
-
that the overload limit apparently had not been challenged.
The NRC

The purpose of this IEB was to inform the licensee of a design deficiency
-involving the minimum flow recirculation paths for emergency core cooling
system (ECCS) pumps which could allow a single failure to result in a
common-cause failure of all ECCS pumps in a system and to request certain
i,
. licensee actions.
The licensee's response to this IEB (KMLNRC 86-209 dated November 7, 1986)
' stated, in part, ". . . the WCGS design configuration of the ECCS pumps
4
and their recirculation paths is not vulnerable to a single failure in the
minimum flow recirculation line . . . that could cause a failure of more
