JAFNPP RESPONSES TO NRC STAFF CONCERNS / STAFF POSITIONS (DELINEATED IN ENCLOSURE 2) RELATING TO FIRE PROTECTION PF-1 Fire Protection Systems Governed by the Quality Assurance Program Closed at the Exit Meeting on August 18, 1978.
The Authority has revised its Quality Assurance Program as indicated in the August 3, 1978 submittal.
PF-2 Back-up Power for CO9 Fire Suppression Systems Closed at Exit Meeting on August 18, 1978. The Authority provided details in the August 3, 1978 submittal.
PF-3 Fire Protection Organization
~
The Authority will adopt the Staff position. Recruiting and
('
interviewing to fill the vacant positions is in progress.
PF-4 Fire Brigade Training Drills The Authority will adopt the Staff position.
While each fire brigade will participate in at least one drill each quarter, only one (1) drill will be a major complex drill involving a number of personnel in addition to the fire brigade.
PF-5 Control of Welding, Cutting, Grinding and Open Flame Work The Authority will. adopt the Staff position and meet the requirements of NFPA 51B.
PF-6 Fire Fighting Procedures The Authority will adopt the Staff position.
PF-8 Fire Door Supervision The Authority is conducting an engineering study to
~
determine actions required to implement the NRC staff position.
A schedule is being prepared for the develop-ment of our answers to your
- ncerns on these issues and
. 8, 1978.
It is expected will be provided to you by 1 that implementation of all required modifications can be completed by December 31, 1980.
PF-9 Interior Hose Station (See PF-20)
The Authority will adopt the Staff position.
Hose reach tests are currently being conducted to identify those areas where additional fire hose stations should be installed.
Where modifications are required, they are expected to be completed by December 31, 1980.

PF-ll Fire Hazard Analysis The Authority will adopt the Staff position.
Implementation of the Staff position is subdivided into three parts (See PF-8 above).
PF-12 Exterior Hydrant and Hydrant Hose Houses The Authority will adopt the Staff position with the following exceptions:
1)
Expeditious clearing and removal of snow in the area of hose houses is a matter of current practice.
The Authority does not intend to implement any specific administrative controls in this area.
2)
The fire hoses stored in exterior hydrant hose houses will be subjected to the same tests (at the same frequency) as the hose used at safety-related
{-
hose stations in the plant.
Since Technical Specification, Appendix A, Table 4.12.3 and NUREG s.
0123, Revision 1, require hydrostatic testing of safety related hoses once every three years, test-ing of all hoses used at JAFNPP is expected to be completed within three years of the date that Tech-nical Specification Amendment 34 (Fire Protection) became effcctive, that is March 2, 1981.
PF-13 Yard Area Fire Hazards The Authority will adopt the Staff position.
PF-14 Post Indicator Valve Operators The Authority.will adopt the Staff position.
(
PF-15 Fire Suppression Water System Valve Supervision The Authority had adopted the Staff position.
The valves of concern in the fire protection system have been locked in the appropriate position and are checked on a monthly basis as part of Operations l
Surveillance Test F-ST-40G, titled " Locked Valve Surveillance".
~
PF-16 Relay Room Fire Protection The Authority will adopt the Staff position.
The staff.
at JAFNPP is currently developing procedures to bring the reactor from hot shutdown to cold shutdown with an assumed complete loss of every cable, system or component in the relay room.
The procedure has been
" walked through" to verify feasibility, manloading re-quirements and to estimate the time required to reach the cold condition.
Further, some modification of plant systems is being studied to:
1) improve
h7 communications; 2) reduce the manloading; 3) simplify the evolution and 4) reduce the time required to achieve and maintain the cold condition.
The scope of the modifications required is expected to be well defined by December 31, 1978 and modifications borne of the study should be completed by December 31, 1980.
PF-17 Control Room Fire Protection The Authority will adopt the Staff position.
Modifications such as a rated fire barrier between the kitchen and the remainder of the Control Room as well as replacement of the wooden cabinets in the kitchen area are expected to be completed by December 31, 1980.
PF-18 Testing of Carbon Dioxide Fire Suppression Systems Preoperational testing of the carbon dioxide total flood systems was completed during 1974.
These tests were witnessed by a representative of NELPIA and CO2 design concentrations were verified as part of those tects,
(
except for the Relay Room.
While the subsystem serving the Relay Room was " puff" tested, total flood was not conducted due to the potential effect on the process computer, ECCS Logic panels, offsite power protective relays and other equipment in the Relay Room.
Results of the total flood tests are tabulated below:
Design Actual Hazard Area Concentration Concentration North Emergency Switchgear 50%
56%
Room South Emergency Switchgear 50%
58%
l Room
{
East Electric Bay 50%
60%
West Electric Bay 50%
57%
Cable Room 50%
60%
Cable Run Room South 50%
50%
Cable Run Room North 50%
57%
Since no total flood test of Relay Room was conducted, the the Authority will increase the discharge timer setting-for that area to assure satisfactory CO2 concentration.
l The setting will be increased from the calculated value
(
of 129 seconds to 155 seconds.
In addition, the dis-l charge timer setting for the Cable Run Room South will be l
increased from 185 seconds to 205 seconds to provide additional assurance that CO2 concentration will meet or exceed the design requirement.
(
PF-20 Interior Fire Hose Stations The Authority will adopt the Staff position with the following exceptions:
1)
The Authority provided in their submittal dated August 3,1978 the results of calculations con-firming that at least 65 psig pressure exists at the highest elevation hose station outlets in the plant.
It should be noted that the responses in the August 3 submittal were compared with the requirements for Class II services listed in NFPA 14-1976 and these minimum requirements specifically apply to the stand pipe outlet rather than the hose nozzle.
In addition, the August 3 submittal used the terms " nozzle discharge pressure", " fire nozzle" and " nozzle pressure" a number of times.
In each caae, the correct term should have been
" outlet" or " stand pipe outlet".
2)
With respect to the staff concern relating to the pressure drop associated with the couplings used on the fire hose, the hose manufacturer has informed the JAFNFP staff that the couplings used are designed to meet Federal Specification WW-C-621E (Coupling Assembly and Hose) and was accepted by Factory Mutual on May 17, 1962.
In addition, manufacturer has informed the Authority that the couplings of the type used at JAFNPP were compared to expansion ring type couplings with respect to pressure drop.
The results indi' ate that the type of couplings c
used at JAFNPP experiences approximately 0.5 pounds more pressure drop at 100 gpm than the expansion ring couplings.
It was also demonstrated that essentially identical pressure drop exists under both turbulent and laminar flow for entire length of the hose.
PF-21 Safety-Related Motor Control Centers t
The Authority will adopt the Staff position.
Part 1 of PF-21 (verification that each MCC containing cables of both divisions is not required for safe shutdown) will be implemented as part of PF-ll.
l PF-24 Safety-Related Pump Rooms-Ventilation Air Intakes I
The Authority will adopt the Staff position.
l The modifications required to implement the Staff j
position are expected to be completed by December 31, 1980.

PF-25 Emergency Lighting The Authority will adopt the Staff position.
The Authority will implement part 1 of this Staff position by modification of the existing 125 VDC emergency lighting system.
The modifications are expected to be completed by December 31, 1980.
2)
Emergency lights, with the exception of those in the Control Room, will be marked to provide easy identification.
The normal Control Room lighting consists of 273 fixtures, all of which are supplied from emergency power.
Therefore, no specific special marking is required.
Emergency AC lighting in other areas of the plant will be marked for easy identification and completely relamped every 2 years.
Since the average lifetime flourescent tubes used in these fixtures is approximately 28 months, relamping at 2 year intervals should assure 7
(
adequate lighting under emergency conditions.
No other administrative controls with respect to emergency lighting are proposed.
PF-26 Reactor Building Elevation 344'6" Battery Rooms - Air Flow Monitor Closed.
The LPCI battery room ventilation systems have air flow monitors that will detect and alarm low air flow conditions that might exist due to failure of fan motors; failure of motor to fan couplings or loss of air flow due to improper damper positions or other air l
flow-path blockage.
Loss of air flow is annunciated at local ventilation control panels and alarms on these panels are in turn annunciated in the Control Room.
PF-28 Manual Fire Fighting Equipment The Authority will adopt the Staff position.
Procurement, distribution, storage and training in the use of the equipment is expected to be completed by June 30, 1979.
PF-29 Control of Combustibles The Authority will adopt the Staff position.
l PF-30 Brigade Leader Training l
The Authority will adopt the Staff position.
The training required to implement the Staff position is expected to I
be completed by June 30, 1979.

PF-31 Post Indicator Valve Labeling The Authority will adopt the Staff position.
Procurement and installation of the signs is expected to be completed by December 31, 1978.
PF-32 Diesel Fire Pump Room Sprinkler Head Spacing The Authority will adopt the Staff position.
Implementation of this Staff position will be concurrent with other engineering studies (see PF-8).
