JAMES A.
FITZPATRICK NUCLEAR POWER PLANT RESPONSES TO USNRC DRAFT SAFETY EVALUATION REPORT RELATING TO FIRE PROTECTION Item 3.1.1 Interior llose Stations (PF-9)
Electrically safe fire hose nozzles have been provided for areas con taining electrical hazards.
Administrative controls have been established to prevent access to manual fire fighting equipment from being restricted by temporary storage of materials within the plant.
Three hundred psi test, single jacket, lined hose has replaced unlined linen hose on those hose stations which are provided for the protection of safety-related structures and systems.
Item a.l.2 Valve Supervision Valves in the fire water system are either locked in the correct position or electrically supervised.
Further, the correct positioning of all valves in the system are being verified on a monthly basis.
Item 3.1.8 Ventilation Systems - Safety Related Pump Rooms (PF-24)
SP-1 & SP-2 Details of any modification to the ventilation system associated with the safety related pump rooms will be furnished to the USNRC by December 31, 1979.
Item 3.1.9, Alternate Shutdown Capability - Relay Room / Cable 3.3.17 Spreading Room The Authority is reviewing the FitzPatrick Plant alternate shutdown capability with respect to a severe fire loss in the Relay Room or in the Cable Spreading Room.
Complete development of procedures to allow the plant to be brought to a cold shutdown condition in less than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> cannot be completed until the study which is being performed for the Commission's staff Position PF-ll (See item 3.2.1) has been completed.
The study associated with PF-ll will provide the de tailed information with respect to the loss of safety related cables and/or com-ponents.
Once it has been determined which cables and components would no longer be available for use in achieving the cold shutdown condition, the Authority will then proceed with the development of any necessary modification proposals and/or procedures to provide this alternate shutdown capability.
The Authority will iaake the modification proposals (if any) available for review by the Commission no later than December 31, 1979, which should allow completion of any modification, if required, by October 31, 1980.
Item 3.1.10 Exterior Hydrant Hose Houses (PF-12)
Damaged doors on exterior hose houses have been repaired or replaced.
Item 3.1.14 Control of Combustibles (PF-29)
The turbine oil system valves and other piping system valves that could allow drainage of com-bustible fluids if improperly positioned have been locked in the proper position, and are being checked monthly.
Diesel Fire Pump Room 3prinkler Head Spacing Item 3.2.4 (PF-32)
As indicated to you in our letter dated Feb.
8, 1979 an engineering study has been performed to verify that the diesel fire pump room sprinkler head arrange-ment provides adequate coverage that protects the entire room.
Item 3.3.1 Detector Testing The fire detection systems at the FitzPatrick Plant were designed and constructed in accordance with the following National Fire Protection Association Codes dated 1967:
72A Local Fire Protective Signaling Systems 72B Auxiliary Signaling Systems 72C Remote Station Signaling Systems 72D Proprietary Signaling Systems Item 3.3.2 Signaling Circuits Supervision (PF-19)
Fire detection and signaling systems are installed in the following 12 areas:
1.
Relay room 7.
Emergency gen.switchgear room N 2.
Cable room 8.
Emergency gen.switchgear room S 3.
Cable run room N 9.
Electric bay tunnel W 4.
Cable run room S
- 10. Electric bay tunnel E 5.
Electric bay W ll. Radwaste cable and sample room 6.
Electric bay E
- 12. AC equipment room In addition, actuation and alarm devices are provided for the water spray system and for the total flooding carbon dioxide system.
In order to respond to the NRC concerns, the Authority plans to review each specificatici and the associated vendor's drawings to evaluate the existing system, in parallel with the current PF-19 effort, currently scheduled to be completed by August 1979.
Item 3.3.3 Fire Alarm Annunciation in the Control Room The Authority has tested the fire alarm bell (annunciator) in the control room under a noisy condition in which all of the other annunciators in the control room were also alarming.
Under this condition, the bell is audible from any point within the control room and the Authority therefore considers this item to be closed.
Item 3.3.4, Fire Pump Performance / Capacity 3.3.5 The Authority plans to perform the tests indicated to assure satisfactory performance of the fire pumps.
These tests are currently scheduled to be completed during the snubber inspection outage which should commence on March 30, 1979.
Following com-pletion of the tests, the Authority will provide the Commission with the required data to demonstrate satisfactory performance or will provide details of additional tests, repairs or modifications if required by July 1, 1979.
Item 3.3.7 Total Flooding CO2 Suppression Systems - Ventilation System Interlocks The Authority will review the design of the ventila-tion systems which serve the areas listed in the draft SER.
For those areas which are not properly interlocked with the carbon dioxide suppression systems, the Authority will develop modifications to effect isolation of the ventila' tion systems to preclude the loss or dilution of the carbon dioxide.
The review of the ventilation system design will be complete and the scope of any required modifications will.also be determined by September 1, 1979.
This will allow modifications to be implemented during the spring 1980 refueling outage.
Item 3.3.9 Exposed Structural Steel (PF-22)
The Authority has committed to study the problem of exposed structural steel and where necessary, provide protection of the structural steel where failure could jeopardize safe shutdown.
This study is being conducted to satisfy the Commission's con-cern which was outlined in PF-22 and is expected to be complete by July 31, 1979.
Item 3.3.11 Crescent Area Fire Protection (PF-23)
The Authority is performing a study relating to a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rated barrier between the east and west portions of the crescent area.
The Authority has also committed to study the feasibility and desir-ability of converting the suppression sys tems associated with the HPCI and RCIC turbines to automatic actuated systems.
Both portions of this study are expected to be complete by August 23, 1979.
The Authority is reviewing the moving of the fire protection actuation " pull boxes" at the head of the stairs leading to the west crescent area.
We intend to either move the " pull boxes" outside of the locked area or to move the locked gate to another location to eliminate the in terference.
This modification will be complete by Spring 1980.
Item 3.3.12 Electrical Cable Penetration Qualification (PF-27)
The Authority has committed to perform a study and test to de termine the fire resistance rating of electric cable penetration seals and also deter-mine and implement the necessary modifications to assure a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rating of these seals.
The study and testing is expected to be complete by January 7,
1980.
Item 3.3.13 Ventilation Duct Penetrations The Authority will review ventilation duct pene-trations with respect to the presence of fusible link operated dampers for the areas listed in this item.
For those ventilation duct penetrations in which the currently installed dampers are inadequate or non-existent, the Authority will develop modifi-cations to upgrade the penetrations by installation of rated UL-listed fusible link dampers.
The review is expected to be completed before December 31, 1979 and modifications should be complete by July 1, 1980.
Item 3.3.15 Testing of Carbon Dioxide Fire Suppression Systems (PF-18)
The Authority is planning testing of the carbon dioxide fire suppression systems installed in safety related areas to demonstrate that a satis factory concentration of carbon dioxide can be achieved and maintained for the design period in all parts of the area if existing documentation cannot sup-port or establish that the current system will provide this protection.
The study will review the pre-operetional test data and other documen-tation in an effort to establish that the existing installation is adequate without performing full scale discharge tests.
The Authority will provide the Commission with details of this study by August 1979.
Should the study not clearly indicate that the Commission's concern will be satisfied, we will also provide details with respect to proposed testing and/or modifications to satisfy the Commission's concern by August 1979.
Item 3.3.16 Flame Retardant Coating the Authority has reviewed the flame retardant status of the cabling in the relay room and cable spreading room at the FitzPatrick Plant.
Our re-view indicates that the cable installed in those rooms passed flame tests which are now idcntified as the IEEE 383 tests.
This data was originally provided to the Commission in the January 11, 1977 response to Branch Technical Position 9.5.1 (page 10, Subparagraph f.) and we therefore consider this item closed.
