Unresolved Items
Unresolved items are matter about which more information is required
to determine whether they are acceptable or may involve noncompliance
or deviations.
New unresolved items identified during this inspection
are discussed in paragraphs 5.a, and 8.
5.
Permanent Plant Fire Protection Systems
An i..spection was made of the permanent fixed fire protection systems
which had been installed.
Most of the facility's permanent fire protec-
tion systems had not yet been installed or the installations were not
complete.
The following items were inspacted:
a.
Fire Pumps
The inspection of the fire pumps indicated that the installation did
not fully meet all the requirement of National Fire Protection
Association Standards No. 20 (NFPA-20), " Cent ri f uga l Fi re Pumps"
The electrical power supply arrangement to the electric fire , amp
was sized for ordinary motor protection and not for locked rotor
current as required by Section 6-3.4.2 of NFPA-20.
The locked rotor
current rating for this pump motor is approximately 2200 amps, but
the circuit breaker for the pump controller is set at 440 amps.
Furthermore, the main breaker to the switchgear supplying the pump
circuit was only rated at 1600 amps.
The arrangement of the
pre 3:;ure sensing line or pipe from each pump discharge pipe to each
pump contro'ler does not conform to the requirements of Section
7-5.2.1 of NFPA-20 due to the following:
piping is 3/8 inch where
as a minimum of 1/2 inch is required; check valves or restrictive
orifices are not provided in the piping; and, test connections are
not provided in the system as required.
Section 9.5.1.1 of the licensee's FSAR states that the fire protec-
tion system installations will comply to the requirements of the
o : <3
c b J As t
a,
.
.
-3-
applicable National Fire Protection Association standard or code.
In addition Section 5.E.2(c) of the licensee's " Fire Protection
Evaluation" states that the fire pump installation will conform to
'Ge criteria of NFPA-20.
The substandard fire pump installation is
a failure to meet a commitment to the NRC and is identified as
Deviation Item 395/79-17-01, " Substandard Fire Pump Installation"
The electric fire pump is rated at 2500 gpm at 125 psi.
Tests
conducted on this pump by the licensee indicated that approximately
180 psi will normally be provided in the fire protection water
system when no water is being discharged from the system.
An even
higher pressure will be provided on the piping system beneath the
elevation of the pump discharge.
Sections 3-12.1.3 and 3-12.1.4 of
NFPA-13, " Sprinkler Systems" and Sections 6-4.1 of NFPA-14, " Stand-
pipe and Hose Systems" requires valves and fittings in systems in
which the pressure exceeds 175 psi to be of the extra heavy pattern
or equivalent.
Section 2-9.6.1 of NFPA-20 requires pumps driven by
constant-speed motors to be provided with approved relief valves
where the pump shutof f pressure plus static suction pressure exceeds
the pressure for which the system components are rated.
A relief
valve was not provided for the electric driven pump.
As noted
above, the licensee's FSAR states that the fire protection systems
will meet the criteria of the applicable NFPA Standard on Codes.
The licensee agreed to provide the NRC with assurance that all
valves or fittings in the fire protection water, sprinkler and
standpipe systems will not be damaged from the over pressure.
This
item is identified as Unresolved Item 395/79-17-02, " Water 'ressure
Rating of Fire Protection System"
b.
Fire Pump Room Sprinkler System
The sprinkler system for the diesel fire pump room was not provided
with a test connection for testing the system's water flow (paddle
type) alarm indicator.
Section 3-16-6.3 of NFPA-13 requires that
waterflow alarm devices are to be tested by actual waterflow through
the system.
The licensee's FSAR Section 9.5.1 states that the
facility's fire protection systems will meet the applicable NFPA
standards and codes.
During this inspection the licensee in f o rmed
the inspector that the alarm indicator portion of the system was not
completed but that an approved test connection will be provided for
this sprinkler system.
This item is identified as Inspector Follow-ap Item 395/79-17-03,
" Fire Pump Sprinkler System Test Connectior ' f or review upon installa-
tion of the test connection.
c.
Fire Protection Systems Inspection Progrim
The fire pump installation, fire protet* ion water system, control
valves, fire hydrant and fire hydrant ho e houses have been turned
over the the licensee by the contractor (lCC).
The licensee had not

yet initiated a test program for these systems.
These procedures
are currently being prepared. The licensee stated that until the
procedures are issued, the following inspections will be made:
(1) Run the fire pumps once a week
(2) Visual inspection of control valves once a week
(3) Visual inspection of hydrants - monthly
(4) Visual inspection of Hydrant Hose Houses monthly
Pending preparation of these procedures by the licensee and subse-
quent review by the NRC, this item is identified as Inspector Followup
Item 395/79-17-04, " Fire Protection Surveillance Procedures"
6.
Construction Site Fire Protection / Prevention Program
An inspection was n.ade of the construction site fire protection pre-
vention program. The follcwing items were inspected:
a.
Fire Brigade
The licensee has delegated to the contractor the responsibility for
the organization and training of the construction site fire brigade.
The organization and training requirements of the brigade are included
in DCC's " Accident Prevention Standard Manual"
A review of the
fire Lcigade organization roster indicated that the following number
of personnel were on the brigade; first shift, 29 people; second
shift, 12 people;
and week ends and holidays, 6 people.
A review
of training records indicated that trainning for the brigade was
normally conducted on the first and third Tuesday of each month.
Additional training had also been provided by the State of South
Carolina at locations away from the site,
The last training
recorded on DCC Form 70-7 was February 6, 1979.
DCC advised that
add:tional training had been conducted but not, recorded as required
by DCC's " Accident Prevention Standard Manual.
However, DCC stated
that future training would be properly recorded.
b.
Control of Combustibles
There ias not a specific procedure covering the control of combustible
mater
s throughout the Summer Const ruction Site.
However, this
item is addressed in various housekeeping and work control procedures
such as, Daniel's " Construction Safety Handbook", OSHA requirements,
etc.
Recently, the licensee initiated a plan to require fire
retardant treated wood scaf folding within the reactor building.
However, there are a number of existing combustible scaffolds that
remain in the reactor building in which the licensee does not
contemplate removing or replacing with noncombustible scaffolding.
In general all of the guard rails, hand rails, toe boards and most of

the wood structural scaffolding supports are combustible wood.
The
licensee plans to restrict the use of combustible scaffolding planks
to the reactor building only. The license does not have a commitment
with the NRC to restrict the use of combustible scaffolding within
the plant during this construction stage as is the normal industry
practice and as required by current NRC regulatory Guide 1.120 " Fire
Protection Guidelines for Nuclear Power Plants"
c.
Welding and Cutting Operations
Neither the licensee nor the contractor require welding and burning
permits for welding and burning operations, and do not have a specific
procedure listing the fire protection safety requirements to be
followed during these operations.
However, acceptable safe practices are listed in DCC's " Construction
Safety Handbook"
The supervisors for employee's assigned to welding
and burning operations are required to instruct and insure that
their subordinates follow safe practices during welding operations.
Fire watches have been assigned by the Contractor to various areas
to help assure that welding and burning operations are safely con-
ducted.
The licensee does not have a commitment with the NRC which
woild require the administrative controls as outlined in NFPA-51B
" Cutting and Welding Processes"
However, three welding operations
within the reactor building were observed and acceptable safeguards
were being followed.
d.
Fire Protection Systems and Equipment
The requirements and frequency for the inspection and test of fire
protection equipment are outlined in DCC's " Accident Prevention
Standard Manual"
Approximately 375 extinguishers consisting of 341
dry chemical, 25 carbon droxide and 8 wheeled dry chemical units,
are provided on the site.
All extinguishers are visually inspected
weekly by fire watch personnel.
A detail inspection is provided
monthly.
This inspection program meets the requirements of NFPA-10
" Portable Fire Extinguishers"
Ten fire extinguishers were examined
and found to have been inspected and tested as required.
The exterior fire protection water systems including fire pumps,
control valves, fire hydrants and hydrant hose houses have been
turned over to the licensee
The Contractor is no longer respon-
sible for conducting the surveillance and operational test on these
items.
Paragraph 5.c contains additional information on this item.
The contractor was fabricating a tank truck for fire brigade use.
This truck will contain an 8,000 gallon water tank and is to be
equipped with a 350 gpm, 150 psi, skid mounted, fire pump.
Additonal
fire fighting equipment is to be provided on this truck but the
exact type and quantity had not been determined.

QA Records Storage
Section 17.1.17.2 of the licensee's FSAR states that the permanent QA
records and other constraction related deciments will be under the
management and control of the SCE&G QC Group and will be stored in an
area that, " affords protection against destruction or deterioration
caused by fire"
The description of the construction site records
storage facility is provided by SCE&G Quality Assurance Procedure No. 16.
This procedure states that during the construction phase a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire
rated facility equipped with a dry chemical or gas fire protection system
will be provided. The procedure does not pr_oide details of the construc-
tion and installation requirements for the storage room and fire protection
system provided.
An inspection was made of the construction site QA records storage
room
which is located in the construction site administrative building.
This
room is approximately 15 x 40 feet in size with a 10 foot high ceiling.
The walls are reinforced concrete and the ceiling is concrete on top of
an exposed metal deck.
The licensee has determined that the fire rating
of the room enclosure is 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />.
A class A (3-hour) fire door is provided
into the room but the door is not designed or arranged to be automatic
self closing as required by NFPA-80, " Fire Doors", and NFPA-232, " Records
Protection"
Air conditioning duct penetrations into the room are provided
with 1 1/2 hour rated fire dampers.
The value or this enclosure is
reduced due to 1 1/2 hour rated fire dampers and non self closing fire
door.
A total flooding, high pressure, carbon dioxide fire protection system is
provided for the records storage room.
This system is automatically
operated by fixed, temperature rate conpensated, heat detectors.
The
detectors are supplied power from a 120 volt AC power source which is
also connected to the emergency secondary power supply for the site
telephone system.
There is no provision for a control panel to provtde
electrical supervision to the detector and carbon dioxide actuation
circuits as required by Sections 1-8.2, 1-8.3, 1-8.4, and 1-8.5 of NFPA-12,
" Carbon Dioxide Extinguishing Systems", f u rthe rmo re , the door into the
room is not automatic self closing or arranged to close automatically
upon operation of the carbon dioxide system as required by Sections
2-2.2.1 and 2-4.4.1 of NFPA-12.
These items significantly reduce
reliability and effectiveness of the fire protection system.
The current
NRC requirements for QA records storage facilities are included in NRC
This guide requires QA records to be stored in a
minmum 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> rated enclosure which is provided with a fixed fire protec-
tion system or a duplicate set of records are to be maintained.
The
design of the records storage facility is required to meet the construc-
tion and protection requirements of NFPA-232 for " Vital records"
It
appears that the current NRC requirements did not exist at the t~ime the
construction license was awarded.
Therefore, the licensee does not have
a commitment to the NRC to provide a standard storage facility during the
construciton phase.
Approximately 20% of the records stored within the
existing facility are reported by the licensee to be "one of a kind" and

probably could not be replaced if destroyed by fire. The failure of the
existing storage facility to meet current criteria is listed as Inspector
Followup Item 395/79-17-05, " Substandard Fire Protection Features for QA
Records Storage", pending further review by the licensee and NRC/NRR.
8.
Safety Records Storage Warehouses
Section 17.1.13.2 of the licensee's FSAR states that level A and B safety
related items will be stored in a fire resistant building or equivalent
Construction site warehouse Nos. A and B are used by the
structure.
licensee for storage of safety related items which fall into the level A
and B protection classification.
These warehouses are not fire resistant
or fire resistive buildings as defined by NFPA-220, " Building Construction",
but are all metal construction and meet the noncombustible / limited-
combustible construction classification of NFPA-220.
These warehouses
are provided with preaction type automatic sprinkler systems and appear
to comply with the FSAR as equivalent fire resistant structures.
However, the value of the sprinkler protection for these buildings has
been reduced due to the construction of the following unsprinkled areas:
Two 40' x 40' and one 20' x 24' combustible storage decks in warehouse A;
a 14' x 30' and 20' x 40' classroom in warehouse B; and, an 8' x 60'
combustible shed adjoining west side of warehouse B (between warehouses A
and B) which is used for storage of oil, lubricants and other miscellaneous
storage.
The lack of sprinkler protection in the above areas could
result in a delay in the operation of the automatic sprinkler systems in
the event of fire which could increase the fire loss and water damage to
safety related items stored within the building.
NFPA-13, " Sprinkler
Systems", requires sprinkler systems to be installed throughout a building.
Section 4-4.11 of NFPA-13 specifically requires protection beneath storage
decks.
The licensee's FSAR does not appear to indicate the type of fire protec-
tion required for the level A and B storage buildings in order for these
buildings to qualify as an equivalent fire resistant structure.
Therefore,
this item is identified as unresolved item 395/79-17-06, '" Fire Protection
for Safety Related Storage Warehouses", pending further evaluation by the
licensee and NRC.
