Operational Safety Verification
The NRC inspectors verified that the facility was 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 by reviewing facility records.
The. NRC inspectors, by observation, interview of personnel, and review of
documents, verified that physical security was being implemented in
accordance with the site security plan and that radiation protection
activities were controlled.
By observing valve position, electrical breaker position, control room
indication, and making containment entries, the NRC inspectors confirmed
the operability of the coolant charging system, safety injection system,
and the accumulator safety injection system.
Selected NRC inspector observations:
On May 10, 1986, during a routine plant tour, the NRC inspector
observed approximately 25 heavy cardboard containers in the hallway
on the north end of Elevation 2000' of the auxiliary building.
During a routine plant tour on May 13, 1986, the NRC inspector
observed the containers still present on Elevation 2000'.
Step 3.1.2
of the licensee's Procedure ADM 13-102 prohibits the storage of
combustibles in safety-related areas. This failure to follow a
procedure is an apparent violation (482/8613-03).
On May 29, 1986, licensee personnel informed the NRC inspectors that
on April 29, 1986, during plant startup (Mode 3 at the cine), RHR
Valve EJ HV-8809B, " Train B Discharge Header To Cold Leg Loops 3 and
4," was closed to stop backleakage from the reactor coolant system

into the RHR system piping. The backleakage was due to the failure
of check valves in the line to seat tightly. Subsequently, the
)
,
licensee initiated an engineering evaluation (EER 86-EJ-02) of the
)
,
l
RHR system to determine if the system could perform its safety
l
function with Valve EJ HV-8809B closed. The engineering evaluation
l
determined that the RHR system had not been analyzed in this
condition, and therefore, it could not be verified that the system
)
could provide the required minimum flow for accomplishing the
system's safety function assuming a single failure. The RHR system
)
was in this lineup (Valve EJ HV-8809B shut) for approximately
49 hours5.671296e-4 days <br />0.0136 hours <br />8.101852e-5 weeks <br />1.86445e-5 months <br /> between April 20-22, 1986. Technical Specification 3.5.2
requires that if one subsystem of the ECCS is inoperable, the
l
subsystem must be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or the
l
plant must shut down. The licensee is taking the following actions
as a result of this event:
l
Procedures are being written to define actions to be taken
j
during plant heatup if RHR temperature increases.
,
Details of this event have been made required reading for all
licensee operators so they will be aware of the consequences of
i
shutting certain RHR valves.
A licensee event report (LER) will be submitted to the NRC.
The NRC inspectors will review the LER and related activities and
j
l
document their findings in a subsequent inspection report.

i
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
inspector considered the following items while inspecting surveillance
activities:
Testing was being accomplished by qualified personnel in accordance
with an approved procedure.
The surveillance procedure conformed to TS requirements.
I

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 met the required limits.
Surveillances witnessed and/or reviewed by the NRC inspectors are listed
below:

STS IC-447, Revision 2 " Channel Calibration Nuclear
Instrumentation System Power Range Incore-Excore"
STS IC-214, Revision 2, " Analog Channel Operation Test Nuclear
Instrumentation System Power Range N41 Protection Set I"
Selected NRC inspector observations are discussed below:
On May 16, 1986, the NRC inspector observed a portion of the
performance of STS EJ-202 and then reviewed the completed
surveillance procedure. During this review, the NRC inspector
-observed that the test performer and the independent witness had just
completed testing .'B' Train Valve EJ HV-8809B, but instead of signing
off Steps 5.1.2, 5.1.3 and 5.1.4, both had signed off Steps 5.1.6,
5.1.7, 5.1.8, and 5.1.9, which are the steps for Valve EJ HV-8809A.
This is an apparent violation (482/8613-01).

Selected NRC inspector observations are discussed below:
On May 16, 1986, the NRC inspector reviewed completed WR 02222-86.
.The NRC inspector observed that, contrary to written instructions
delineated in Block 18 of the WR, the limitorque serial number had
not been written down in Block 39 of the WR.
This failure to follow
procedure instructions is an apparent violation of TS 6.8.1 which
requires that, " Written procedures shall be established,
implemented, and maintained . . . ."
(50-482/8613-02)
7.
Environmental Qualification of Electric Equipment
Instrument Transmitters
While performing routine maintenance work on safety-related pressure
transmitters that were located in a harsh environment area (steam and
feedwater piping room), licensee personnel observed that some of the
pressure transmitter field splice (FS) boxes had terminal boards for
'
making wire terminations rather than splices, which were specified for
wire terminations in environmentally qualified electric equipment located
in a harsh environment. Sheet 5 of Specification E-17000A, page 5,
" Termination Of Selected Class 1E Devices." (harsh environment) delineates
the accepted method for making these terminations,
j
Based on this observation, the licensee inspected 12 pressure transmitters
,
and 4 valve controller FS boxes and determined that terminal boards in
lieu of splices were used in 10 of the 16 FS boxes inspected. The problem
appears to have been caused by errorn made in both design and
installation. The following is a summary of the type problem identified
in each instrument.
Six main steam pressura transmitters FS boxes had terminal boards
installed due to a design error in that the wrong specification was
provided on installation / inspection insttuctions. The affected
transmitters were AB-PT-0525, AB-PT-0526, AB-PT-0535, AB-PT-0536, and
AB-PT-0545. Specification E IR8900, " Raceway, Notes, Symbols, and
Details," (non-harsh environment) was called for rather than
Specification E-17000A.
Two atmospheric relief valve controllers and three main steam
pressure transmitter FS boxes had terminal blocks installed even
though the installation instructions specified splices. The affected
instruments were AB-PY-0002, AB-PY-0004, AB-PT-0534, AB-PT-0524, and
AB-PT-0515.
.
.
.
.
11
The FS box for Main Steam Pressure Transmitter AB-PT-0546 had splices
(which is right) in it even though the installation / inspection
instructions called for terminal boards.
Based on the above findings, the licensee performed an inspection on 101
additional instruments, and found the following deficiencies in the
indicated instrument's FS box:
Connection boxes for 8 containment recirculation sump level
instruments were not filled with silicone fluid as required by
Installation Drawing J-481-0002, " Installation Specifications
Transmitter Wiring and Mounting." The affected instruments were
EJ-LE-0007A, EJ-LE-0007B, EJ-LE-0008A, EJ-LE-0008B, LF-LE-0009A,
LF-LE-0009B, LF-LE-0010A, and LF-LE-0010B.
Connection boxes for 8 level instruments for monitoring water level
in the RER pump rooms and the auxiliary building sumps were not
-
filled with silicone fluid as required by Installation Drawing
J-481-0005, " Installation Specifications Transmitter Wiring and
Mounting." The affected instruments were LF-LE-0101A, LF-LE-0101B,
LF-LE-0102A, LF-LE-0102B, LF-LE-0103A, LF-LE-0103B, LF-LE-0104A, and
LF-LE-0104B.
Connection box terminations for 4 containment cooler temperature
elements did not have potting compound applied to terminal blocks as
required by Installation Drawing J-558B-0008, " Installation
Specifications Transmitter Wiring and Mounting." The affected
instruments were GN-TE-0060, GN-TE-0061, GN-TE-0062, and GN-TE-0063.
The licensee is presently expanding the walkdown inspections of
environmentally qualified electrical equipment to include a sample of all
special connections (i.e., splices) located in this equipment. Pending
further review and inspection of the licensee's evaluation, the matter is
considered an unresolved item (482/8613-04).
No violations or deviations were identified.
8.
Survey of Biofouling Detection Instrumentation on Cooling Water Heat
Exchangers
,
The NRC inspector interviewed licensee personnel and reviewed the Final
Safety Analysis Report (FSAR) to determine whether instrumentation was
available on safety-related equipment cooled by open-cycle service water
system (essential cooling water) which would detect biofouling.

The containment air coolers were found to be the only pieces of
safety-related equipment that were being monitored for cooling water flow.
However, this instrumentation was not online but was used to measure flow
at least once per 31 days as part of the TS surveillance requirement for
the containment cooling system. Operability was demonstrated by a flow
rate of equal to or greater than 2200 gpm to each cooler group. A flow
rate less than this on one or more cooler groups required the operator to
enter the TS action statement.
The licensee was found to be concerned by the problem of biofouling. This
was evident by their program of inspecting, at 6-month intervals,-
selected components using service water and essential cooling water.
Included in this sample was fire protection piping.
No violations or deviations were identified.
