Installation and Inspection of
Category 1
Miscellaneous
Elec-
trical' Systems
CD-T-16,-(Rev. 10)
Structural Steel and Q-Decking
Based on this review, it appears that the above procedures meet the
licensee's commitments in Section 9B of the Vogtle FSAR and the Unit
Fire Protection Quality Assurance Program Evaluation Report dated
March 1,1988, (File X4BJ01, Log: 7323). This report evaluated the
existing ~ QA program applied to design, construction, installation,
and testing of the fire protection features provided for Vogtle
'.
Unit 2.
Included in this report is a description of the Fire
Protection Finalization Program, FP-3, which is intended to verify
specific fire protection features by a combination of design reviews
and walkdowns. The fire protection features which are to be verified
are:
Underground Utilities
Fire Detection System
Sprinkler System
Fire Hose Cabinets
Fire Door Assemblies
- afe Shutdown Conduit
The rr sults of this program will be reviewed during a future NRC
-
inspection.
Additionally, the inspector reviewed the following test records for
l
the dates indicated. The test data and frequency associated with the
i
construction fire protection systems inspecticas were found to be
satisfactory with regard to meeting the requirements of procedure
i
SD-T-05.
(1)
File X7BA01-C11Q - Monthly Fire Extinguisher Inspection Report:
The construction Fire extinguishers were inspected each month
between January 1988, and April 1988, except not all extin-
guishers located outside the power block were inspected during
February 1988, s'ue to manpower shortage to conduct inspections.
The inspector ve. ified that all extinguishers inside the power
block safety related plant areas were inspected during this
period.
(2)
File X7BA01-C3A - Monthly Hose House Inspection Report: The
inspector verified that the plant Hose Houses and Hose boxes
were inspected between October 1987, and April 1988, except
records for the February 1988, inspection was not located in the
QA ' records vault.
During the inspection the licensee satis-
factorily located copies of these records which were to be
placed in the appropriate file in the records vault.

Permanent-Plant Fire Protection Features
The= status of the construction and installation of the permanent plant
features for Unit 2 is a follows:
a.
Fire Pumps, Storage Tanks, Yard Mains, Hydrants, Fire Hose Houses
(Module 640538)
The fire water supply and distribution system is essentially 100%
installed and under operational control of Unit 1.
Some lead-in
water supply piping to Unit 2 sprinkler systems has not yet been
flushed.
Test blanks have been installed between the system
isolation valves and Unit 2 preaction sprinkler valves prior to
system installation.
The test blanks will be removed after the
header piping is verified clean.
For Unit 2, this provides reesonable
assurance that foreign materials have been removed from the
-undergrovri lead-in piping system and that sprinkler systems are free.
from foretgn material. Georgia Power Company requested NRC approval
by letter dated July 7,1987, for this alternate flushing technique.
SER approval was provided by letter dated October 26, 1987, from the
NRC that concluded the proposed change was acceptable. The inspector
reviewed sprinkler system detail and tagging chart Drawing 2X4DF00290
(Revision 1), and flushing Procedure VEGP-2 (Revision 0), Attachment
10.3, Temporary Flushing Modifications, which indicate the instal-
lation of the test blanks and the lead-in piping flushing procedure.
. Based on this review, it appears that the installation and removal of
the test blanks are adequately controlled through the use of drawings
and the procedures for Vogtle Unit 2.
b.
Automatic Sprinkler Systems
The installation of 124 Unit 2 sprinkler systems is nearing 70%
completion. Design is completed fc
all sprinkler systems. A review
was made of the QC inspection and hydrostatic tests for the below
listed systems:

These tests appeared to meet the 200 psi test pressure for two hour s
duration testing requirements of NFPA-13, Sprinkler Systems and are
satisfactory.
A .walkdown of these systems was conducted ar.d it appeared that the
sprinkle. coverage was in general, provided at the ceilir.g level. It
was noted that criteria for placement of in-tray spray systems was
deleted for these and other plant areas, except the cable spreading
>
rooms.
Also it was noted that sprinkler piping supports in these
areas utilize NFPA-13 hanger and sway bracing designs rather that
rigid type supports which were used on Unit 1.
These sprinkler
'
design changes were accepted by the NRC in a SER dated October 26,
1987.
Based upon the inspectors review it appeared that the
-
installed systems reviewed met the licensee's design criteria as
approved by the SER.
c.
. Fire Door
Fire door installation is proceeding with approximately 60%
completed. An inspection was made of the following fire doors to -
verify that the appropriate QA inspection records were provided as
designated in the Vogtle Unit 2 Fire Protection Quality Assurance
Program Evaluation Report.
No discrepancies were noted.

Control Room Temporary Fire Barrier Wall
For a period of Unit 1 operation and Unit 2 construction, the Unit 1
and Unit 2 centrol rooms were separated by a gypsum board three hour
fire barrier wall on the Unit 2 side between the two control rooms.
By letter dated December 21, 1987, Georgia Power notified the NRC of
the proposed removal of this fire barrier prior to completion of
Unit 2.
The inspector reviewed the licensees commitments to provide
interim fire protection features denoted in the above letter to
,

verify their implementation to preclude the remaining Unit 2 control
room construction activities from compromising the safety of the
Unit 1 control room.
The inspector reviewed the Unit 2 fire watch
log and verified that appropriate fire watches had been established
since January 1988. Other features including structural steel fire
proofing, portable fire extinguishers, welding permit controls
l
'
appeared to be in place, except it was observed during the
walkthrough that the committed Unit 2 fire hose cabinet immediately
adjacent to the control room entrance (labeled Station No.
2-23-01-R4-197) was not maintained available for fire brigade use due
to construction related obstructions in the areas consisting of a
construction workstation, stacked five gallon cans of construction
,
materials, ladders and crew boxes weich restricted accessibility to
'
!
the cabinet.
In addition, the fir 2 hose cabinet door latch was
inoperable and construction electrical power cords were being stored
i
inside the cabinet. The failure to maintain this fire hose cabinet
'
capable of spraying all Unit 2 control room areas is a failure to
meet a commitment made to the NRC and is identified as Deviation
(425/88-32-01), Failure to Maintain Manual Fire Hose Suppression
!
Capability for the Unit 2 Control Room.
Except as noted above,
within the areas examined, no additional violations or deviations
were identified.

Oil Collection System (64100)
The Vogtle FSAR Section 9BC.7.a states that an oil collection system is
provided for the reactor coolant pump.. Each Uni: 2 reactor coolant pump
is provided with an oil collection systcm arranged to collect oil from
potent?al leakage points and drain this oil into a drain tank.
Potential oil leakage points for each pump have been provided with an oil
containment system consisting of a lower bearing oil pot drip pan, upper
oil level detection drip pan, oil cooler drip pan, and oil lif t system
enclosure.
These enclosures are connected to oil collection piping headers which are
designed in accordance with the Bechtel Nuclear Project Classification
List (414) denoted as Nuclear Safety Class 4 (Quality Group D) as defined
by Regulatory Guide 1.26. and are supported to Nuclear Seismic Category 1
to withstand a design basis seismic event. A separate tank of 300 gallons
capacity is provided for each pump's lubrication system oil collection
piping headers. Each collection tank is verted and provided with a flame
arrestor.
Each tank's capacity is sufficient to hold the full volume of
oil from the reactor coolant pump.
The inspector reviewed the following documentation of the oil collection system
and it was verified that the system was being installed under a QA/QC program.
