United States Nuclear Regulatory Commission Mr. Harold R. Denton, Director Information Related to NRC/NRR Fire Protection Site Visit Page 2 During observation of the BVPS-2 Control Roan Shift Supervisor's Office, tne NRC Fire Protection Reviewers noted that the smoke detector is located in an apparently restricted space above the solid suspended ceiling of the office. DLC plans to renove the existing steel wall which separates the BVPS-2 and BVPS-1 Shift Supervisor's Of fices creating one conmon office. DLC is evalua-ting the effectiveness of smoke detection currently provided on the BVPS-1 portion of the office (at ceiling level) in detecting smoke due to fires below the ceiling of the conbined office. The results of this evaluation will be avail able by March 9,1987. During their review of the BVPS-2 smoke detector spacing, the NRC review-ers noted three locations where they felt detectors should have been installed and were not. Therefore, the reviewers requested that DLC perfonn a review to ensure that detectors have been installed where required. The results of this review are to be documented in a letter to the NRC. DLC has begun the review and final results will be available by March 9,1987. Based on recent discussions with BVPS operations personnel, the response provided in the noted reference for Iten 3 (Fire Brigade Training)is being clarified. The response should read as follows: Prior to fuel load all fire brigade members who would be expected to respond to a fire at BVPS-2 will undergo training specifically related to firefighting in the BVPS-2 Cable Spreading Roon. This includes all BVPS-2 licensed operators, all shif t radiation technicians, all shift cheni sts, and all non-licensed BVPS operators. Not included in this training are BVPS-1 licensed operators who would not ce expected to respond to a fire at BVPS-2. The training will incluoe walkthroughs of 1 the Cable Spreading Roan in full brigade gear. i l f d i

Clarification of Structural Steel Deviation The NRC Fire Protection Reviewer requested addi tional infonnation to ensure that failure of unprotected structural steel in the upper elevations of the Service and Auxiliary Buildings (Fire Areas SB-5 and PA-5) will have no adverse impact on the safe shutdown capability.

Response

FSAR Appendix 9.5A provides results of the fire protection safe shutdown ana-lysis for these areas and concludes that safe shutdown can be achieved assuning loss of all safe shutdown cables and equipnent located in these areas. FSAR Table 3.2-2 provices a sunmary of Seismic and QA Category I structures. As indicated in the referenced table, the Seismic Category I seisnic and torna-do missile barrier is located at the 780' elevation for the Service Building and- at 773'-6" for the Auxiliary Building. These are the floor slabs in Fire Areas 58-5 and PA-5. Failure of the structural steel above the tornado missile barriers will not cause danage to cunponents below as the missile boundary is capable of with-standing collapse. In addition, FSAR Section 3.68.1.3.4.3 states in part for the Service Building that ". .

                                    .- if non-seismic Category I portions of the structure fail, no adverse effects on adjacent Seisnic Category I structures or conponents will occur."

In conclusion, the above infonnation provides adequate justification for the

SRP deviation on unprotected structural steel.

Conduits / Penetration Seals Item C.S.a(3): The Standard Review Plan states that openings inside conduit larger than 4 inches in diameter should be sealed at the fire barrier, and that openings inside conduit 4 inches or less in diameter should be

  • sealed at the fire barrier unless the conduit extends at least 5 feet on each side of the fire barrier and is sealed either at both ends or at the fire barrier with noncombustible material to prevent the passage of smoke and hot gases, w; S + 5 te. Se A.

Differences from the SRP: g derdl. Cow kined.

For these cases, the installation of a fire seal at the first opening on one side of the barrier, combined with fire wrap from the seal to the barrier, effectively extends the fire barrier. This method provides the same degree of protection as would sealing at the barrier.

Amendment 14 9.5A-121 February 1987

BVPS-2 FSAR

SUBJECT:

One-Hour Fire Wrap of Ductwork Item C.5.a(4): The Standard Review Plan states that penetration openings for ventilation systems should be protected by fire dampers having a rating equivalent to that required of the barrier (see NFPA-90A, " Air

                                     - Conditioning and Ventilating Systems"). Flexible air duct coupling in ventilation and filter systems should be noncombustible.

Differences from the SRP:

a. Certain fire dampers were located outside of fire barriers and the ductwork portions from the dampers to the barriers are protected with a 1-hour fire-rated material.

r

  • J Ventilation ductwork passing through fire barriers is protected on both sides of the barrier with a 1-hour fire- a rated material and tutomatic detection instead of fire dampers installed at the barrier.

{ g J Ventilation ductwork passing through fire barriers is protected on the outsides of the barrier with a 1-hour fire-rated material and automatic detection and suppression instead of fire dampers. Justification:

a. Due to changes in boundaries of a portion of the plant's fire areas it became necessary to install fire dampers in completed ventilation systems. Extensive redesign and field i

modifications would have been required to locate the fire dampers inside the barrier. The fire dampers are located as close to the fire barriers , as possible and the ductwork from the fire dampers to the barrier is wrapped with a 1-hour fire-rated material. Fire wrap is also installed on the ductwork beyond the fire damper to the first support if required to ensure the ductwork's integrity. l The fire severity in these areas is less than 1 hour on both sides of the barrier or automatic suppression and detection has been provided.

In order to ensure the system availability in the event of a fire in an area not using this system, the ductwork was protected.with a 1-hour fire-rated material and fire dampers were not installed in the fire barriers. The fire severity in these areas (SB-1, SB-2, SB-4) is less than 1 hour and automatic general area fire detection with local and control room alarms has been provided.
d. -*@ Due to plant layout the ventilation ductwork for the emergency switchgear ventilation and the battery room exhaust system were required to be installed in other fire

{ areas (CV-1, CV-3, SB-3) not serviced by this equipment. In order to ensure the system availability in the event of a fire in an area not using these systems, the ductwork was protected with a 1-hour fire-rated material and fire dampers were (CV-1, notCV-2, installed in the fire barriers. These fire areas and CV-3) are provided with automatic suppression and detection with local and control room alarms.

Our with'several hundred fire tests over the past years has invariably shown that larger objects with n W thermal mass (e.g. large HVAC ducts) heat up more slowly.

3M Interam" E-50 Series Fire Protection Mat Installation Booklet, Issue #5500-004, dated September 30, 1986 Section III.G. on page 5500@-7 of this booklet states that using two layers of Interam" E-54A (ncminal .8" total thickness) would be a conservative approach to fire protecting HVAC ducts. This very conservative approach was mentioned as a possibility to insuru that air and objects within the HVAC would not exceed 325'F maxinum temperature. When no critical electrical cables lay within the ductwork, the 325'F

I OL 29 8" N:35 31 EU:LD:tG 207g C.0:0 00 Stone & Webster January 29, 1987 Phge 2 requirement seems very conservative. General structural steel and supports fire protection requirements are to keep the maxinum tanperature below 1200'F and the average teqperature below 1000*P. Coincidentally, M Fire Test #87-14 was just run on January 28, 1987 which indicated a cold side maximum tenperature on 18 gauge galvanized sheet metal of 283'F after one hour. This sheet metal was fire protected with one layer of E-54A and one layer of E-53A secured with 1/2" wide stainless steel banding at 8" spacing. Preliminary results are attached. I hope this information is useful to you, sincerely, Randall G. Koza senior Fire Protection Engineer 612/733-4554 RGKamz Encl.

SUBJECT:

Modified Fire Doors Item C.5.a(5): The Standard Review Plan states that door openings in fire barriers should be protected with equivalently rated doors, frames, and hardware that have been tested and approved by a nationally

                                        ' recognized laboratory. Such doors should be self-closing or provided

, with closing mechanisms and should be inspected semiannually to verify that automatic hold-open, release, and closing mechanisms and

latches are operable. 'See NFPA 80, " Fire Doors and Windows.")

a. Fire door assemblies have been modified from their tested configuration by the addition of security hardware and alarm equipment as required by NRC regulation.

w # e. Safeguardt Sw'IAm,t i b. Rolling steel fire doors have had the lower jam modified from the tested configuratio[n to allow for the installation ' Q and removal of equipment, &r the dood is not fire-rated. __SI i c. Special purpose-type door assembliesC(for example, oversized W f oors. pressure-resistant doorTN_ (containment access doors / hatches) ed water-tight doors]) are not UL rated. Justifications: t

a. These modifications were made following the guidelines suggested by Underwriters Laboratories. They are similar to those made on BVPS-1 which were reviewed and found acceptable by the NRC. The door areas have either automatic detection and suppression or manual fire fighting equipment available in the areas. The security alarmed doors also have remote monitoring capability via the security system ,

j .bscr/ 4 video monitors and the alarm function in the event the door is left open, which would alert personnel of an abnormal ) (pg,9,g.my) condition in these areas. ! b. The rolling steel doors in the north and south safeguards l areas are not used to separate adjacent fire areas but are i ' used to separate the stairwell within a fire area from the l remainder of the area. Since the safeguards areas are normally unoccupied and the fire severity is less than 1/2 i l hour, this arrangement is acceptable. ! The rollinghteelJoorbetweentheturbinebuilding(TB-1) l and thersourn n"i e= waansuildina]EsoSafin the railway ' bay, is not a fire-rated door because the door was purchased and installed as an exterior door to the turbine building 4 before the 505B was envisioned.

SUBJECT:

New Fuel Area Item C.7.1: ' The Standard Review Plan states that automatic fire detection should alarm and annunciate in the control room and alarm locally.

           ' Difference from the SRP:

Automatic detection in the new fuel storage area is not required. Justification: The new fuel storage area is an enclosed cubicle within the fuel building, combustible loading in the area, and the building in general, is extremely low.j alo comousticles are stored in rne area w postulated fire in any area of the fuel building will not impact the ability to safely shut down the plant. Since the fuel building access is controlled, and the building is a low traffic area, potential for accumulation of transient combustibles is negligible. Fire hose stations and portable extinguishers are provided. 1 L - ALairlrakve con h o ls w ,11 h t 9/ n d e t 4 , L n. w

SUBJECT:

Fire Hydrant Spacing Item C.6.b(7): The Standard Review Plan states that hydrants should be installed approximately every 250 ft. on the yard main systen. Difference fran the SRP: Fire Hydrant No. 16, located outside of the southwest corner of the Turbine Building, . is located 340 feet fran Fire Hydrant No.15 which is located outside of the South Office Shops Building. Justification: Fire Hydrant No.16 has been relocated due to field interferences. Sufficient lengths of hose have been providt:d in the associated hose cart houses to pro-vide coverage in the event of a fire. The specific hazards in the area are the Main Transfonner and the two Station Service Transfonners. These transfonners have been provided with autonatic deluge suppression systens.}}
