I 6.
Monthly Maintenance Observation (62703)
Station maintenance activities of safety-related systems and components were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides, industry codes and standards, and were in conformance with technical specifications.
The following items were considered during the review:
limiting conditions for operations were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as applicable; functional testing and/or calibrations were performed prior to returning components or systems to service; quality control records were maintained;
- An unresolved item is a matter about which more information is required to determine whether it is acceptable or may involve a violation or deviation.

activities were accomplished by qualified personnel; parts and materials were properly certified; radiological controls were implemented; and fire prevention controls were implemented. Work requests were reviewed to determine the status of outstanding jobs to assure that priority was assigned to safety-related equipment maintenance which may affect system performance. The following maintenance activities were observed / reviewed:
Unit 1 FCV-3227A repair 1A Inverter repair Unit 1 Containment Building tendon surveillance & inspection 1C Diesel Generator PMs Fire Damper inspection and maintenance j
Service Water battery racks repair

No violations or deviations were identified.

Operational Safety Verification (71707)
The inspectors observed control room operations, reviewed applicable logs and conducted discussions with control room operators during the report period.
The inspectors verified the operability of selected emergency systems, reviewed tagout records, and verified proper return to service of affected components.
Tours of the auxiliary building, diesel building, turbine building and service water. structure were conducted to observe plant equipment conditions, including fluid leaks and excessive vibrations. The ' inspector verified compliance with selected Limiting Conditions for Operations (LCO) and results of selected surveillance
,
tests.
The verifications were accomplished by direct observation of monitoring instrumentation, valve positions, switch positions, accessible hydraulic snubbers, and review of. completed logs, records, and chemistry l
results.
The licensee's compliance with LCO action statemants were reviewed as events occurred.
The inspectors routinely attended meetings with certain licensee management and observed various shift turnovers between shift supervisor, shift foremen and licensed operators.
These meetings and discussions provided a daily status of plant operations, maintenance, and testing activities in progress, as well as discussions of significant problems.
The inspector verified by observation and interviews with security force members that measures taken to assure the physical protection of the facility met current requirements.
Areas inspected included the organization of the security force; the establishment and maintenance of gates, doors, and isolation zones; that access control and badging were proper; and procedures were followed.
On June 18, 1987, during the performance of STP 80.10 " Diesel Generator 2C i
1000 KW Load Rejection Test", the licensee found an electrical problem in which 2C diesel generator would not have non-essential engine protection (NEEP) when aligned to 2B battery. The licensee has found a wiring error in termination cabinet 38B on 1TB1-3. The non-essential engine protection

is bypassed during emergency starting of the diesel generator. Therefore,
from an emergency start situation the diesel generator was not affected.
This item is unresolved pending further investigation (348; 364/87-14-02).
On June 9,1987 at approximately 10:30 a.m., the licensee attempted to perform FNP-0-PMP-1087 " Test for Isolation of Fire Dampers in the Control Room Air Conditioning System."
The NRC resident inspector was present to
observe the test. The test could not be performed because both trains
"A" and "B" were found to be electrically inoperable.
(See Unresolved Item 348-364/87-13-02).
Each damper is composed of four sections with each section operating independently of the other three sections.
An investigation of the electrical components of the fire dampers was initiated by the licensee with the following results:
a.
Links were found open in terminal box A1TB015 on train
"A" and also in terminal box B1T019 on train "B".
'
b.
Additional links were found open in field wired terminal boxes located at each fire damper.
c.
The terminal box for damper XV2782AD was improperly wired in that there were two jumper wires installed.
d.
The SRD's (explosive release device) electrical wiring in each damper were not connected.
e.
One damper did not have the SRD's installed.
The licensee rectified the wiring, closed the links and verified the installation in accordance with the drawing.
FNP-0-PMP-1087 was performed again on June 11, 1987 on train "A" dampers.
The test was unsatisfactory due to mechanical binding of the dampers and a electrical problem.
Inspection indicated that wiring supplied with SRDs had separated from the SRD and shorted against the metal damper / duct work.
The licensee cleaned, lubricated and exercised the train "A" dampers. The dampers were then mechanically actuated. The damper would not fully close and latch with air flow in the duct. The dampers were actuated without air flow in the duct and this time performed as intended.
Testing on train
"B" dampers indicated similar results.
The original fire dampers, located in the horizontal duct work, were installed during plant construction.
The firestats and SRD circuits were tested satisfactorily by startup test procedure 400-3-444.
The fire dampers are designed to operate by melting of thermal links or by anticipatory electrical signals from firestats and SRD's.
The firestats are designed to operate at lower temperature.
The Fire Protection Re-evaluation program required that fire dampers be relocated in the
]
vertical run of duct work at the penetration in the penthouse floor.
l Bechtel Change Notice BM-3088, CWR-32.85 and MWR-30023 accomplished this l
and the work was completed on November 21, 1980.
The dampers were

,
mechanically tested without air flow on December 9, 1980 and the mechanical work was functionally accepted on December 23, 1980. The SRD's were relocated under Bechtel Change Notice BE-4502 and completed under CWR 1-32.86 and MWR-26982 on February 18, 1981. The inspection and functional.
testing performed was inadequate to prove the work. The four fire dampers were re-inspected as late as March 1982. During this inspection the wiring was found to be incomplete on the SRDs on all four dampers in that none of the wiring to the SRDs had been terminated.
Two MWRs were written to complete the work.
These MWRs were never implemented.
Inadequate corrective actions on the fire dampers are addressed in NRC inspection i
report 348, 364/87-11 as a Potential Enforcement Finding, The inspections and testing of completed work, which is required before
,
functional acceptance to prove operability of the system or component, was inadequate or had not been implemented.
This resulted in the electrical modification to the dampers to be incomplete and therefore the electrical initiation portion of the fire dampers was inoperable beginning on February 18, 1981 to June 1987.
The inspection and testing of the completed work as required by 10 CFR 50 Criterion X and XI were inadequate
'i in that the uncompleted wiring circuits, the jumpers installed in a field terminal box, and the open links in the field terminal boxes were not identified as not conforming to documented instructions, procedures and drawings.
This is a violation (348, 364/87-14-01).
