Findings
Additional information on the "open" items and on the " closed" items
in paragraph 5.a marked by an "*" are listed below. The below listed
numbers correspond to the numbered items in paragraph 5.a.
?
(1)Section IV.C.3.c of EFPP states in part that the automatic sprinkler
systems conform to the requirements of National Fire Protection
Association Standard No. 13 - (NFPA-13), Sprinkler Systems. The
automatic sprinkler systems installed as part of the plant's fire
protection modifications do not fully meet the criteria of NFPA-13.
The following are examples of where the systems do not fully meet
the provisions of hTPA-13.
(a) The sprinkler piping for pre-action systems which contain
over 20 ' heads is not supervised 'as required by Section
5-3.5.2 of NFPA-13.

(b) The sprinkler deflectors in many areas are located up to
twice the distance beneath ceiling / roof structures than that
permitted by Section 4-3 of hTPA-13.
(c) Serious obstruction to discharge of water spray from the
systems in some areas is provided by ventilation ducts,
electrical cable trays, conduit, piping and building struc-
tural supports.
This problem is most acute in the cable
spreading room.
Sections 4-4.13 and B-4-2.3 of NFPA-13
require that additional sprinkler protection be provided in
areas where obstructions are located.
(d) Closed type nozzles for water spray type sprinkler systems
located long distances beneath ceilings or roofs arg not
provided with heat collectors to assure prompt actuation in
the event of fire as required by Section 3-16.8 of hTPA-13.
(e)
'
Test pipes (main drains) arranged to properly test the water
supply to each system are not provided as required by Section
2-9 of NFPA-13.
(f) The shut off vaives to the water flow alarms on wet pipe
systems are located on the discharge side of the retarding
chamber in lieu of the supply side as required by Section
3-17.4.3 of hTPA-13.
(g) Valves to the water flow alarm devices to the sprinkler
systems are not of the type which can be sealed or locked in
position as required by Section 3-17.4.5 of hTPA-13.
(h) The flange bolts on the flange fitting in the supply piping
to the sprinkler / standpipe system at the intake structure
are too short and do not meet the provisions of Section
3-13.1 of NFPA-13.
This situation may also exist on other
flange type fittings.
This item is a failure to meet a commitment to the NRC and is iden-
f-
tified as Deviation Item (50-321/80-02-02 and 50-366/80-02-02),
9ubstandard Automatic Sprinkler Systems.
(5)&
(8) To control the s_torage of combustible materials signs have been
posted _throughout the east cableway of Unit I which read
" CAUTION - Storage of Combustibles Prohibited". However, during
(
this inspection, approximately 45 boxes of HEPA filters were
!
stored -in this area.Section III.C.4. (b) of the EFPP states in
part that the storage of transient combustibles within this area
will be controlled by procedures and signs.
The storage of
j
combustibles within this area is a failure to meet a commitment
to the NRC and is identified as Deviation Item (50-321/80-02-03),
Storage of Combustibles in East Cableway of Unit 1.

(9) Installation is not complete but is not required until after the
1980 refueling.
(12) Oil curbs have been installed around the RHR pumps for Units 1
and 2.
However, the oil curbs for the Unit 2 RHR pumps are
nonfunctional since this area is approximately 25% full of an
oil-water solution. The failure to install and adequately maintain
this oil catchment area which was required by Section III.C.4 of
the EFPP is a failure to meet a commitment to the NRC and is
identified as Deviation Item (50-366/80-02-04), Inadequate Oil
Catchment Facility for Unit 2 RHR Pumps.
(13) Refer to above item (1). Also, the connection from the exterior
fire protection water distribution system to the sprinkler / stand-
pipe system within the river intake structure is not provided
with an independent outside control valve as required by Section
3-3.1 of NFPA-24, Outside Protection.
Section IV.C.2.a of the
EFPP states ir part that the exterior fire protection water
system is designed in accordance with NFPA-24. This discrepancy
is a failure to meet a commitment to the NRC and is identified as
Deviation Item (50-321/80-02-16 and 50-366/80-02-15), substandard
Water Supply to the Sprinkler / Standpipe System Within the River
Intake Structure.
(16)Section III.C.4 of the EFPP states in part that the storage of
transient combustibles within the river intake structure will be
controlled by appropriately marking the floor areas. However,
the floor areas are not marked or signs are not provided to pro-
hibit the storage of combustibles within the intake structure.
This item is a failure to meet a commitment to the NRC and is
identified as Deviation Item (50-321/80-02-05 and 50-366/80-02-05),
Signs to Prohibit Storage of Combustible Materials Not Provided
at River Water Intake Structure.
(17) Refer to above item (1).

(22) Fire doors with a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> fire rating (Class B) have been instal-
led in wall openings between the control rooms and the peripheral
rooms (toilet and kitchen and administration areas). However,
these fire doors have not been provided with a door closer as
required by Section 2-8.4 of NFPA-80, Fire Doors.Section IV.B.I.j
of the EFPP states in part that all openings in fire rated walls
will be provided with doors, hardware and frames which are listed
by Underwriter's Laboratories (UL). UL requires that fire doors
be installed in accordance with the criteria of NFPA-80 to retain
their UL listing. This item is a failure to meet a commitment to

the NRC and is identified as Deviation Item (50-321/80-02-06 and
50-366/80-02-06), Substandard Fire Door Installations Between
Control Room and Adjacent Areas.
The fire / security doors between the control room and the turbine
building are not provided with positive type latching devices as
required by Section 2-8.2 of NFPA-80.
This item is another
example of Deviation Item (50-321/80-02-06 and 50-366/80-02-06),
Substandard Fire Door Installations Between Control Room and
Adjacent Areas.
(23) Rate of rise (heat) type fire detectors have been installed in
the kitchen adjacent to the control room in lieu of the smoke
detectors specified by Section III.C.I.1 of the EFPP. Thig item
is a failure to meet a commitment to the NRC and is identified as
Deviation Item (50-321/80-02-07 and 50-366/80-02-07), Incorrect
Type Fire Detectors for the Control Room Kitchen.
?
(24) The licensee advised that an evaluation of the control cabinets
within the control room indicated that all cabinets which contained
safety related cables were provided with sufficient ventilation
openings which would permit smoke to escape and activate the area
fire detection system in the event of a fire within the cabinet.
This appears to meet the intent of the FPSER.
(26) Refer to above item (1).
(28) Refer to above item (1).
-
(30) The sprinkler system for the 130' control building corridor is
installed directly over four safety related electrical cabinets.
Water spray protection or prevent. ion has not been provided for
these cabinets as stated by Section III.C.I.4.(g) of the EFPP.
Also, an evaluation apparently has not been made to determine if
the construction of the cabinet will provide adequate protection in
the event of actuation of the Sprinkler System. This is a failure
to meet a commitment to the NRC and is identified as Deviation Item
I
(50-321/80-02-08 and 50-366/80-02-08), Inadequate Protection Against
Sprinkler System Discharge for Four Safety Related Cabinets - 130 Foot
Elevation of Control Building Corridor.
(32) Table 3 Item No. 39 (Response No. 25.a to NRC questions of June 13,
1977) of the EFPP states in part that a mobile platform for fire
fighting operations will be provided in both the northwest and
southwest cable areas for each unit. During this inspection a
mobile platform was not located in the Unit I northwest cable
area.
The platform assigned to the northwest cable area ws
actually located in the southwest cable area of Unit 1.
This
failure to meet a commitment to the NRC is identified as Deviation
Item (50-321/80-02-09), Mobile Fire Fighting Platform Not Provided
For Unit 1 Northwest Cable Area.
(40) Refer to above item (1).

(45) &
(48) The drain piping from the Unit I and Unit 2 Reactor Recirculation
M-G set rooms terminate (discharge) to the floor at the 130 foot
elevation of the reactor building. Tabic 3 Item No. 43 (Response
,,
to NRC question 25.e(3) of June 13, 1977) states in part that the
'
valves in this drain piping system will be locked closed. During
this inspection these valves were found closed but were not locked
in the closed position. This item is a failure to meet a commitment
to the NRC and is identified as Deviation Item (50-321/80-02-10 and
50-366/80-02-10), Control valves in Drain Piping from Reactor Recir-
,
culation M-G Set Rooms Not Locked in Closed Position. These, valves
were, however, locked by the licensee prior to the completion of
the inspection.
(49)Section IV.C.2.c of the EFPP states in part that a floor to
ceiling fire barrier will be provided between each fire pump. A
fire barrier has been provided between each pump; however, the
fire pump controller and battery charger for diesel engine pump
No. 2 is located within the enclosure for fire pump No. 3.
A
fire involving pump No. 3 would possibly result in pump No. 2
becoming inoperative.
The present arrangement does not fully
meet the intent of the EFPP and is failure to meet the conunitment
to the NRC. This item is identified as Deviation Item (50-321/
80-02-11 and 50-366/80-02-11), Inadequate Fire Barrier Separate
Between Fire Pump Nos. 2 and 3.
(52)Section IV.C.3.b of the EFPP states in part that all interior
-
fire protection control valves to the sprinkler systems for
Unit I are designed with electrical valve supervision which will
ring a local alarm when the valve moved to the wrong position.
Also, these valves will be locked in the correct position.
In
addition, the control valves for the unit 2 systems will be
electrically supervised and arranged to sound an alarm in the
control room if the control valves are moved to the wrong position.
The following Unit I sprinkler cystem control valves were provided
with local electrical valve supervision and were found open but not
locked open as required:
l
(a) Cable spreading room
!
(b) HVAC Area at 158' elevation
l
(c) RPS Area
l
l
The following Unit 2 sprinkler system control valves are provided
I
with local electrical supervisor but. do not sound an alarm in the
l
control room as required by the EFPP:
(a) Cable Spreading Room
(b) Corridor at 130' elevation
(c) RPS Area

The above discrepancies are failures to meet a commitment to the
NRC and are identified as Deviation Item (50-321/80-02-12 and
50-366/80-02-12), Substandard Supervision of Fire Protection
Control Valves.
(53) - The licensee's audit of the fire protection administrative control
procedures, Southern Company Services - Fire Protection and Loss
Prevention Audit of Hatch Plant - August 15, 1979, recommended a
number of changes to the existing procedures. These recommendations
are currently .Seing reviewed and existing procedures reevaluated
by the licensee to determine the appropriate corrective action
required. The licensee advised that all required changes will be
completed prior to August 1,
1980. This item is identified as
Inspection Followup Item (50-321/80-02-13 and 50-366/80-02-13),
Licensee's Reevaluation and Revisions to Fire Protection Admin-
istrative Procedures, and will be reviewed during a subsequent
NRC inspection.
~
(55) An air compressor has been provided to refill the self-contained
breathing apparatus which are provided for emergency use. Section
IV.B.4.h of the EFPP states in part that this air compressor will
be located within a special receptacle in the diesel generator
building and arranged for manual connection to an emergency power
supply in the event of loss of offsite power. However, the air
compressor has actually been installed within the water treatment
building in which a power source is apparently not available in
the event of loss of offsite power. This is a failure to meet a
commitment to the NRC and is identified as Deviation Item (50-321/
80-02-14 and 50-366/80-02-14), Incorrect Location of Air Compressor
for Emergency Breathing Apparatus.
6.
Fire Protection QA Program
Documentation is not provided or is not easily retrievable to demonstrate
that the fire protection modifications required by the FPSER and the EFPP
were accomplished under the management control of a Quality Assurance (QA)
'
organization.Section IV.B.7 of the EFPP states in part that the ten QA
,
i,
criteria of Section C of Appendix A to NRC's Branch Technical Position
'
APCSB.9.5-1 (BTP 9.5-1) will be applied commensurate with the controls
described in the operational QA Program and the QA Program for fire protec-
tion will be under the management control of the QA organization. Detail
functional test reports were provided for the fire detection systems, but
inspection procedures, test results, etc. , were not available for the other
modifications.
Also, the fire suppression systems were installed by a
,
'
contractor and it appears that very limited inspections and controls were
provided by the licensee over these installations. The apparent lack of a
fire protection QA program in the following areas listed by BTP 9.5-1:

Fire Pumps (Diesel Pumps)
i
The two diesel driven fire pumps are electrically started with starting
current taken from two banks of storage batteries which are shared by each
engine.Section IV.C.2.c of the EFPP states that the fire pump installation
is consistent with hTPA-20, Centrifugal Fire Pumps. Section 8-2.6.1 of the
3
current edition of NFPA-20 states that each fire pump engine shall be
provided with two storage battery units. This section also states that
this provision is not applicable to installations made prior to adoption of
NFPA-20. The licensee is to evaluate the fire pump installation and deter-
mine if the installation should meet the applicable provisions of the
current edition of NFPA-20. This item is identified as Unresolved Item
(50-321/80-02-15 and 50-366/80-02-15), Substandard Diesel Driven Fire Pump
Installation, and will be reviewed during a subsequent NRC inspection.
