Licensee Action on Previous Inspection Findings a.
(0 pen) Unresolved Item (339/79-03-01): Fire rating of dampers between battery rooms and control room. Documer.tation as to the fire rating of
,
(
these dampers is apparently not at the sita.
The licensee is to forward this data to NRC Region II office for review. Also, refer to paragraph 5.b.(23). This item remains open.
b.
(Closed)
Deviation Item (338/80-03-02):
Inadequate administrative fire prottction procedures. The licensee has revised the " North Anna Fire Protection Plan" procedure to correct this Power Station
-
deviation as follows:
(1) Section 3.5 of the FPP requires all fire brigade members to satisfactorily pass a physical examination for performing strenuous activities.
(2) Smoking restrictions within the plant have been incorporated into Section 4.6.2.g of the FPP.

'
valve numbers and all of the fire protection control valves have been included in the revised procedure. This item is closed.
d.
(Closed)
Noncompliance (Infraction) Item (338/80-03-04):
Excessive time between the inspection and test of carbon dioxide fire protection system for fuel oil pump house.
The licensee has instructed the personnel involved as to the importance of attentien to detail in the performance of scheduled tests required by the Technical Specifi-cations. The correct inspection frequency was followed for the tests conducted on February 20 and August 20, 1980. This item is closed.
i (
e.
(Closed)
Mor. compliance (Infraction)
Item (338/80-03-05), excessive l
time between inspections of fire hose stations.
The licensee has instructed the responsible personnel as to the importance of attention t
to detail in the performance of scheduled tests required by the Technical Specifications.
The inspection records for 1-PT-105.2.1, Hose Rack Inspection - Safety-Related Areas, from January 31 through November 14, 1980 were reviewed and found satisfactory.
This item is
l closed.

g.
(Closed)
Deviation Item (338/80-03-09):
Combustible wood used in I
safety-related areas of the plant. Section 4.3.3.c of the FPP has been I
revised to permit only fire retardant treated wood inside permanent plant buildings.
Sections 4.3.2 and 4.3.3 of the FPP provide l
restrictions and additional controis for the use of combustible l
.
.
.-
materials. During the plant tour the inspector did not detect any wood that was not of the fire restistance treated type.
This item appears to be under control and is therefore closed.
h.
(0 pen) Deviation Item (338/80-03-10): Substandard supervision of fire protection control valves. A number of valves in the fire protection system were found by the inspector to be in the correct alignment, but the valves were not provided with tamper proof seals.
These valves included the following:
valves to containment standpipe systems; diesel fire pump discharge valve and electric fire pump discharge valve.
The licensee does not appear to have taken sufficient corrective action on this deviation.
Therefore, this item remains open.
4.
Unresolved Items Unresolved items are matters 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.b.(2), 5.b.(12), 5.b.(16) and 5.b.(23).
5.
Fire Protection / Prevention Commitments - Unit 2 This inspection evaluated the licensee's progress and action on the fire protection commitments made to the NRC.
The NRC Fire Protection Safety Evaluation Report (FPSER) for North Anna dated February 1979 (referenced by paragraph 2.c.(11) of License NPF-7) and the licensee's Fire Protection System Review (FPSR) dated April 1,1977 with Supplements 1, 2 and 3 were used in this evaluation.
These documents describe the fire protection requirements, commitments and dates of implementation. This inspection was limited primarily to Unit 2 and areas common to Units 1 and 7 Items applicable to both Units are so noted. The commitments and findings are as follows:

Findings Additional information on the "Open" items and items marked "**" in Para. graph 5.a is listed below. The below listed numbers correspond to the numbered items in paragraph 5.a.
i (2) Fire hose has not been provided at each stand pipe hose outlet in the containment as stated in Table 1 of the FPSER.
The hose and equipment are located in a cabinet adjacent to the personnel hatch.
The licensee advised that a commitment was not made to install fire hose at each standpipe outlet but hose was to be provided in the cabinets adjacent to the personnel entrance outside each containment.
Enclosure 1 to VEPCo's letter Serial No. 4581080178 to NRR dated September 29, 1978, states that dry hose connection standpipes will be located within the reactor containment with " lengths of hose (to be located) immediatedly outside of personnel hatch in auxiliary building
,
el 291 ft".
The licensee is to resolved this discrepancy with NRR.
- This item is identified as Unreso1ved Item (338/80-42-01 and 339/80-39-01), fire hose not provided a.t each standpipe hose connection within reactor containment, and will be reviewed during a subsequent NFC insepction.
i (7) VEPCO's letter Serial No. 148/0306679 to NRR dated June 11, 1979 stated that replacement of this damper was not necessary since the ventilation duct was schedule 40 pipe provided with two normally closed seismically qualified butterfly valves in series directly inside the control room wall which would provide the equivalent, or better than a
,
3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> damper. This evaluation was apparently acceptable to NRR.
(8)
This item is presently being evaluated by NRC/IE Resident Inspector.
l (12)
This fire damper was apparently replaced with a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire damper. However, a QC inspection was not made to verify this modifi-cation.
The damper was installed under VEPC0 Design Change No.78-68I and assigned to receive QA Category III surveillance requirements. QA Category III surveillance does not require 100's inspection and the inspection of this damper was waived. Section 3.7.15 of the Technical Specification requires all penetration fire barriers protecting safety-related areas to be functional at all times. Section 4.7.15.b requires penetration fire barriers to be verified functio.nal by a visual inspection prior to declaring a penetration fire barrier functional following repairs or maintenance.
The failure to inspect the fire damper in duct penetration between the Units 1 and 2 cable tunnels is identified as Violation (338/80-42_02 and 339/80-39-02), inadequate QA/QC surveillace of fire damper installation between Units 1 and 2 cable tunnels.
i
'
In reviewing this fire damper installation the inspector reviewed procedure 1-pT-105.1.4, Fire Barriers, which is used for the visual inspection of fire barriers to asure that all penetrations are

i functional.
This procedure does not appear adequate to accomplish the intent of Technical. Specification Section 4.7.15 in that inspection acceptance and rejection criteria are not provied for the various -
penetrations in the fire barriers,- i.e. electrical, mechanical, fire
!
dampers, fire doors, etc.
The licensee agreed to evaluate and revise
,
j this procedure and to advise NRC Region II as to the results of this evaluation and scheduled dates the existing procedure will be revised and implemented. This item is identified as Unresolved Item (338/80-
'
42-06 and 339/80-39-6), surveillance inspection procedure for pene-
'
[
tration fire barriers.
,
(14) The manual sprinkler system for the cable tunnel area had been
,
installed. However, the. installation of the high system in the ceiling
<
area was not complete since the sprinkler heads provided were of the
,
closed type in lieu of the open type as required by the FPSR and the FPSER. The system would have been functional but would not have met the design requirements.
The closed. heads were changed to the open a
type heads on December 11, 1980.
Section Z c.(11) of the operating
'
license required this installation to be completed no later than i
November 1, 1980.
This item is identified as Violation Item l-(339/80-39-05),
failure to implement fire protection modification j
requirements of the operating license.
.
(16)
In general, the installation of the smoke detection -systems do-not fully meet the criterion of NFPA-72E, Automatic Fire Detectors, in
many areas.
The licensee stated that a commitment was never made to
!
the NRC for the installation of the detection systems to meet the provisions of NFPA-72E.
However, the licensee is to review the
'
existing design and installation and provide justification for~the areas in which the detection systems do not meet the provision of
!
NFPA-72E.
This data is to be submitted to NRC Region II by March 15,
!
1981.
This item is identified as unresolved item (338/80-42-03 and 339/80-39-03), substandard smoke detector installations, and will be-reviewed upon completion of the licensee's' evaluation.
i I
(23) The fire dampers are no't standard type dampers and documenation as to the fire resistant rating of these fire dampers is not available
I at the site. The licensee is to provided NRC, Region II, documentation which will indicate the fire resistant rating of these dampers. Also, the dampers located in the ducts which contain the fans do not appear to be held in the open position by means of fusible link devices. The licensee is to reinspect these dampers and make necessary repairs if
!
needed.
This item is considered another example of the previous Unresolved Item (339/79-03-01) and is also applicable to Unit 1.
This item is identified as Unresolved Item (338/80-42-04), fire rating of dampers between battery rooms and control rooms.
(
(28) Refer to above item (16).
.
l (29A)
The installation of the sprinkler. system for the component cooling pumps is practically complete. However, the QC documentation -
i
!
l
>
.-
o
..
.
is not complete and several inspection discrepancies, such as no heat collectors provided for sprinkler heads located in open floor area, have not been corrected.
The system is, however, functional.
These problems are currently identified by Inspector Followup Item (338/80-03-01 and 339/80-03-01), sprinkler system deficiencies, which remains
open.
A total of 200 feet of li-inch hose, one nozzle and two spanner (35)
s wrenches are provided.
However, the hose is stored in rolls and not racked to permit ready use. The licensee is to properly install this hose within the storage cabinet.
This item will be reviewed during a subsequent NRC inspection.
(36) The fire extinguisher is stored inside and near the entrance door into this buidling. This arangement appears to meet the intent of the commitment.
(38)
A fire extinguisher had not been provided for the auxiliary service water building as of December 11, 1980. The licensee advised that an extinguisher would be installed in this building by December 12,1980.
This item was required to be accomplished by November 1,1980 per Section 2.c.(11) of the operating license. This item is identified as another example of Violation (339/80-39-05),
failure to implement fire protection modification requirements of the
!
operating licensee.
(39A) Refer to above item (16).
(43A)
Fire detectors are only installed with the ventilation ducts.
Area detection is not provided and it appears that no additional detector's are required to meet the commitment to the NRC.
However, this arrangement does not conform to the provisions of NFPA-72E. Refer
,
to above item (16).
'
(46)
The fire detectors installed within the main steam valve house t
are located approximately 10 feet beneath the ceiling which 3ee not conform to the provisions of NFPA-72E.
The amount of comui:ibles within this area is exceptionally small; therefore, no additional changes to the detection system appears warranted.
