Dear Mr.Denton:

Carolina Power&Light Company hereby submits additional deviations to the Branch Technical Position 9.5-1 to NUREG-0800. Attachment 1 provides the technical information needed for your review.The deviations were discussed with your staff at an April 30, 1986, meeting.Should you have any questions concerning this letter, please contact Mr.Patrick Carier at (919)836-8165.Yours very truly, SRZ/PPC/mmh Attachment S.R.Zi erman Manager Nuclear Licensing Section cc: Mr.B.C.Buckley (NRC)(W/A)Mr.G.F.Maxwell (NRC-SHNPP) Dr.J.Nelson Grace (NRC-RII)Mr.Travis Payne (KUDZU)Mr.Daniel F.Read (CHANGE/ELP) Wake County Public Library Mr.Wells Eddleman Mr: John D.Runkle Dr.Richard D.Wilson Mr.G.O.Bright (ASLB)Dr.J.H.Carpenter (ASLB)Mr.J.L.Kelley (ASLB)Mr.T.S.Moore (ASLAB)Dr.R.L.Gotchy (ASLAB)'r.H.A.Wilber (ASLAB)Bb0b2402b5 SbObi8 PDR*DOCK 05000400 F PDR 411 Fayettevitte Street~P.O.Box 1551 o Raleigh, N.C.27602 I l4'" 4!4l Flf 1 ll~I 4, FIRE PROTECTION ADDITIONAL DEVIATIONS

SUMMARY

A deviation has been identified from BTP-9.5-1, Section C.5.a (1, 2, 4 and 5)of NUREG-0800 from having fire-rated dampers, doors, and penetration seals in walls and floors designated as 3-hour rated.AREA DESCRIPTION See Tables 1, 2, and 3 for area description. DISCUSSION Tables 1, 2 and 3 identify the location of the doors, HVAC and bus duct penetrations. For those penetrations and doors where safe shutdown equipment is within 20 feet, automatic suppression and detection has been provided on at least one side of the door or penetration. The combustible loading in the areas are considered low to moderate.The doors are manufactured to the same engineering specification as would a 3-hour rated door.The SSA equipment i'dentified within 20 feet radius of the doors or penetrations do not have their redundant counterpart within 20 feet except for MCC-IA-35SA and MCC-1B-35SB (deviation previously identified in NLS-86-040, dated February 13, 1986).CONCLUSION CP&L believes that this deviation is justified for the following: 1.Low to moderate combustible loading in the zone.2.Suppression and detection systems are provided on at least one side of the door or penetration. 3.The SSA equipment identified within 20 feet radius of the doors or penetrations do not have their redundant counterpart within 20 feet except as noted above.Based on the fire, prevention features provided, CP&L concluded that the addition of fire dampers and rated doors would not greatly enhance the fire protection in the these zones and provides an acceptable deviation to NUREG-0800, Section C.5.1 (1, 2, 4, and 5).(0767NEL) 'F ll I

SUMMARY

A deviation has been identified from BTP-9.5-1, Section C.5.b(2)NUREG-0800 from having to consider intervening combustibles between the following: 1)the power and control cable feeding the CCW lA-SA pump, and 2)the CCW 1B-SB pump and related cables.AREA DESCRIPTION Plant Location: Reactor Auxiliary Building Elevation 236 feet Fire Area: 1-A-BAL SSA Area: FAABL3 Fire Zone: 1-A-3-PB Other Safe Shutdown E ui ment in the SSA Area: 1.2.3.4.5.6.7.8.9.10.11.12.13.Air Handler AH-29 Motor Control Centers 1B22SB SW Booster Pumps Air Handler AH-9 Air Handler AH-6 (Local)Air Handler AH-7 (Local)RHR Heat Exchangers CCW Heat Exchangers CCW Pumps CVCS Charging Pumps Air Handler AH-10 Air Handler AH-11 (Local)Auxiliary Feedwater Pumps and lA22SA DISCUSSION The power and control cable is routed in conduit from CCW lA-SA to cable tray raceway which is approximately 100 feet from the CCW 1B-SB pump and related cable.Intervening combustibles are present between these components in the form of IEEE-383 cables located in cable trays approximately 8 feet away (see Figure 1).The location is provided with an automatic suppression system actuated by thermal detection. Ionization detectors are also provided in this location for fire detection. This zone has low combustible loading as described in the SHNPP fire hazard analysis, Section 9.5A.3, Page 9.5A-29.Additional informa-tion for this area is available in licensee submittal NLS-84-245, dated June 12, 1984.CONCLUSION CP&L believes that this deviation is)ustified for the following reasons: 1.Low combustible loading in the area.2.Suppression and detection systems are provided in the area.(0767NEL) C I t' 3.Physically separated by approximately 100 feet.Based on the fire prevention features provided, CP&L concluded that further consideration of intervening combustibles would not greatly enhance fire protection in this zone and provides an acceptable deviation to NUREG-0800, Section C.5.b(2).(0767NEL)
