i RaSPONSE To CHEMICAL ENGINEERING BRANCH REQUEST FOR ADDITIONAL INFORMATION RANCHO SECO UPDATED FIRE MAZARDS ANALSYIS REPORT 1.
NRC REQUEST The Lfranses states that the Updated Fire Nazards Analysis (UFMA) included analyses for several new areas, includists the Nuclear Services Electrical Building.
Since these areas were not included in the 1977 Fire Nazards Analysis (FMA) the Lfcensee shoul1 describe how the fire protection for these areas conforms with Appendix A to Branch Technical Position APCSB (9.5 1).
This response does not need to include the T01 Dieset Generator Bullding, since this has already been evaluated by the staff.
PESPONSE Ta'cle 1 provides a listing of the 1977 FMAR fire areas and the 1987 JFMAR fire areas and Identifies the new and revise-fire areas.
Previous BTP APCSB 9.5-1 or NUREG 0800 comparisons were reviewed to determine if the new fire area (s) had been previa"sty evaluated for conformance to the Standard Review Plan.
The fire areas created since 1977 (with the exception of the TDI Bldg) are:
NSEB Fire Areas (75 through 91.2)
Previously reviewed by NiC (SER dated 6 4 85) l NSRW Pump Area (110)
New designatI*
of an area previously reviewed (See BTP 9.5 1 submittat dated 8 31 76 regarding safety related pump areas).
Transformer Attey (70)
This fire area was design =ted in 1987 UFNA to attow tracking of cabling routed through the area for NN!/ICS and EFIC
)
moolfications.
The transformer atLey was described in item 5.a.13 of the NSEB NUREG 0800 submittals j
(11 15 84, 3 21 85, 4 12 85, 4 16 85, and 5 14 85).

9 RESPONSE TO CNEMICAL ENGINEERING 3 RANCH REQUEST FOR ADDITIONAL INFORMATION RANCHO SECO UPDATED FIRE MAZARDS ANALSYlS REPORT 2.
NRC eEQUEST The licensee has referenceo a number of documents, related to the post fire safe shutdown nethodology, that were not listed in the July 1985 (UFNA).
The licensee shoutd identify how this erhtotdology has changed from that which was evaluated by the staff in the May 19, 1986 safety evaluation.
RESPONSE
A comparison of the July 1985 List of post fire safe shutdown equipment (July 1985 UFNAR Reference 17) and the 1987 UFhAR post-fire safe shutdown equir ent List (1987 UFNAR Reference 18) was performed to identify the equipment added or deleted, and the bases for the changes.
Table 2 provides this comparison.
The changes to the post fire safe shutdown equipment ilst are summarized belown o
Components which are skid mounted with the truce die' generators are considered part of the dieset generati
) and are no longer itemized on the safe shutdown equipment st.
o Addition of the TDI diesel generators and associated j
equipment, power panels, and cabling.
o Addition of the EFIC cabinets and associated controt j
cabling.
o Additions to the auxillary feedwater system, main feedwater system, and main steam system associated with the EFIC i
modifications.
o Certain steam generator instruments were deleted from the
]
safe shutdown equipment list.
New instruments essociated j
with the EFIC system were added to the list.
o changes of valve numbers were incorporated.
l o
As a result of modificatio9s to the electrical distribution
- system, changes were ade to the lists of eloctrical buses which supply power to coeponents required to operate for safe shutdown.

RESPONSE TO CHEMICAL ENGINEERING BRANCH REQUEST FOR ADDITIONAL INFORMATION RANCHO SECO UPDATED FIRE MAZARDS ANALSYl3 REPORT 2.
RESPONSE (cont) o As a result of changes in the design of the NSEB MVAC system, the Train A and Train 5 normat/ essential isolation was moved from dampers MV 50104 and MV 50105 to dampers HV 50126 and MV 50127.
(Note:
The finst NSEB NVAC system design set the normat/essentist isolation at NV 50104 and MV*50105.
This change, as welt as other changes resulting from the evaluation of Appendin a compliance of the finat NSEB HVAC system configuration, wlLL be ref3ected in future UFMAR revisions.)
o Control Room /TSC MVAC system filtration units $FATA an., SFA78 were deleted from the post fire safe shutdown equipment List.
3 These units are not required to ope 7ste to provide conting to the Control Room /TSC.
In the event of fire, the system is operated in the recirculation mode radiological filtration is not required.
o AlthouS1 not required to meet the separation requirements of Appendix R,
Section Ill.G, certain components of the emergency communication system were adved to the safe s
shutdown equipment list to ensure adequate communications capability Is maintained to support alternative shutdown.
o The pressurittr spray valves were added to attow review of possible spurious valve operation.
These valves were previously not included, as spray is isolated by telp of the reactor coolant pumps.
These valves are added for information only and may be deleted from future revletons of the UFOAR.
o The reactor scram breaker cabinets were added to the safe shutdown eqJlpment List for clarity only.
This comparison shows that the differences in saf e sh Jtdown methodolgy result primarity from the recent EFic, TDI, and sstated modifications.
l The NRC review of the flee protection features for'these modifications is documented in the respective Sets.

RESPONSE TO CHEMICAL ENGINEERING BRANCH REQUEST FOR ADDITIONAL INFORMATION RANCHO SECO UPDATED FIRE HAZARDS ANALSTIS REPORT 3.
NRC REQUEST The licens]e states that the UFNA incorporates changes in combuetible toading since the previous FNA.
The licensee should identify where these toadings have increased and the amount of change.
RESPONSE
tsste 3 Lists the combustible loadinga from the 1977 FMAR, the 1985 UFNAR, and the 1987 UFNAR.
Table 3 shows that loadings have, in general, increased throughout the plant.
The increased loadings are attributable to the followings o
Different combustlble calculation methods used in the revisions to the UFNAR.
o Increased cable tray loadings due to cable pulls for recent I
plant modifications.
o Increased conservatism in cable combustible toeding values.
o Watkdown surveys of area combustible loadings performed during plant outages.
Because of the time period in which the surveys were conducted, certaln construction related i
materials are included in the 1985 and 1987 UFNARs er Inaeltu combustible loading.
In addition, the walkdowns conservatively estimated combustible toedings for items not j
normally considered as in situ combustible loading, e.g.
emergency tighting battery casings.
The 1987 UPNAR demonstrates the adequacy of the fire area bounderles to contain a design basis fire using these i
conservative combustible toading values.
(Note:
The 1987 UFNAR did not include the combustible loading due to the charcoal fitter installed on the Auxillary Sullding roof (fire area RG1) as part of the below grade Auxillary Building j
MVAC system modifications completed during the recent plant outage.
This combustible loading increase (approximately 3,800 Stu/sq ft) will be included in future UFNAR revisions.)

NRC REQUEST I
The Licenses states that the Updated UFMA identifies' changes in i
fire protection equipment since the previous'FMA.
.The. Licensee should identify if any fire protection equipment has been deleted.
RESPONSE
The changes in the 1987 UFMAR descriptions of the fire protection equipment for each area result from the fottowings o.
Different interpretations of extent of coverage provided by an area's instattod suppression system.
Table 4 shows the areas where descriptions of cree suppression have been revised.
o Offferent Interpretations of the number of. hose stations considered avaltable from adjacent fire areas for manual fire fighting.
No hose stations have been physicatty removed from the plant.
o Changes in placement of portable fire extinguishers, l
Extinguisher placement is reviewed and modified as required to reflect extinguisher agent improvements, and changes in plant facilities and hazards.
Fire extinguishers are located in accordance with the requirements of MFPA 10.

Note Subsequent to the issuance of the 1987 UFNAR, certain additional changes were made to the fire protection systems T
j o
Analysis of associated circuits lesues related to the dampers i
used to isolate the NSEs carbon dioxide fire suppression systems necessitated the temporary disablement of these systems.
Future Licensing submittels witt reftect the final configuration of these fire suppression systems.
o To ensure that fire eatinguishers are supplled to required locations in a timely manner, information on portable ratinguisher placement will be deleted from the UFMAR and I

RESPONSE TO CHEMICAL ENGINEERING SRANCH REQUEST FOR ADDITIONAL INFORMATION RANCHO SECO UPDATED FIRE MAZARDS ANALSYl3 REPORT 5.
NRC REQUEST Item (6) on page 1-2-states that changes in the fire ratings of Appendix R fire barriers have been incorporated into the UFNA.
The licensee shoutd identify where if any, barrier ratings have been reduced along with justification of the new ratlng.
RESPONSE
The changes in the 1987 UFNAR regarding the fire ratlng of the fire carriers which form fire area bounderles result from a reevaluation of the fire rating of barriers constructed of metal stud and plaster partition.
The fire area bounderles which were reevaluated are detalted in Table 5.
The acceptablLity of the revised barrier ratings is d6monstrated in the UFNAR analysis for each fire ures.
The metat stud / plaster partition construction has been rerated for a one hour fire rating.
The acceptablLity of the new rating is based on the low fire loadings within the fire areas invotved.
