l NRC QUESTION 1:
In the proposed approach, low pressure injection systems appear to be serving as an attemative shutdown capability (as defined in Sez!ans Ill.G.3 and Ill.L of the regulation) for     ,
certain locations of Fire Areas RB-1 and RB-2. However, the proposed LPCI approach does            l
!  not appear to satisfy the " hot shutdown" performance criterion of Section Ill.G.1, Ill.G.2,       !
and Ill.G.3 of Appendix R to 10 CFR 50. Additionally, Generic Letter 86-10 provides further        ,
clarification and staff positions with regard to defining " alternate" and " redundant" shutdown capabilities. In light of these requirements, it appears the proposed LPCI approach would be providing an alternative shutdown capability for certain locations of fire areas RB-1 and RB-2
;  (i.e., the north side of the Reactor Building Units 1 and 2 and the separation zone of the 20' elevation of Unit 1 Reactor Building east and southwest), where the preferred shutdown method (i.e., RCIC) may be unavailable due to fire damage. Please confirm that the proposed LPCI          l approach is an alternative shutdown capability for these locations, as defined in Sections Ill.G.3 !
and Ill.L of the regulation.
CP&L RESPONSE:
Carolina Power & Light (CP&L) Company's Alternative Shutdown Capability Assessment (ASCA) Report defined alternative shutdown as safe shutdown activities requiring use of abnormal operational practices or nuclear system modifications as discussed below:
: 1) Operations:
a) Other than normal safe shutdown activities from the Control Room; b) Operations from the designated alternative control systems locations; I
l           c) Manual operation at equipment location.
l l  2) Modifications:                                                                                  !
!           Rerouting, relocation, or modification of existing safe shutdown system outside a fire area to assure the ability of achieving ann maintaining safe shutdown conditions.

~ .
The ASCA Report, Section 7.2 report also stated that the safe shutdown systems in the Reactor Building consist of two types:
: 1) Normal shutdown systems operated from the Control Room (primarily Train A equipment), and
: 2) Alternative shutdown systems operated locally at the remote shutdown panel or manually in the case of selected valves (primarily Train B equipment).
The components necessary to support the Low Pressure Coolant injection (LPCI) mode of operations for a fire in the Reactor Building North are the same Train B shutdown systems as described in the original ASCA Report for which the exemption request for Appendix R, Section Ill.G.2, was granted. The ASCA Report described the use of the LPCI mode to control vessellevel during shutdown cooling. CP&L's request for an exemption from Appendix R, Section Ill.G.1, was due to the specific requirement regarding maintaining hot shutdown as it relates to controlling vessel level above top of active fuel. CP&L does not consider the use of the LPCl mode in conjunction with rapid depressurization to be outside the current emergency operating procedures which define the normal shutdown capability of the plant.
NRC QUESTION 2:
As discussed above, and in accordance with the defense-in-depth philosophy for fire protection, one reason the use of low pressure injection systems has been accepted as an alternative shutdown capability is that the regulation (Section Ill.G.3) requires fire detection and fixed fire suppression systems in the area undar consideration. However, the CP&L submittals do not describe the fire safety features, combustible loadings, or fire hazards in the areas for which the exemption is requested. Therefore, please provide information which (a) describes the combustible loadings, or fire hazards in the areas for which the exemption is requested; and (b) demonstrates that the fire protection features (detection and suppression systems) provided for Reactor Building fire areas RB-1 and RB-2 are equivalent to that required by Section lil.G.3       l of the r< gulation, or provide technical justification where this level of protection is not provided and LPCI is identified as the post-fire safe shutdown capability.
CP&L RESPONSE:
The ASCA Report for the Brunswick Steam Electric Plant (BSEP), Unit Nos.1 and 2 was submitted on April 24,1984, and supplemented by letters dated December 24,1984, and October 28,1985. The NRC approved the exemption requests contained in the ASCA Report in a Safety Evaluation Report dated December 30,1986, and NRC clarifications were provided in a revision of the Safety Evaluation dated December 6,1989. CP&L's exemption request contained in the ASCA Report, Section 7.2 provided a detailed description of the fire protection features available to support the requested exemption from Appendix R, Section Ill.G. The fire protection features described in the ASCA Report provide a increased level of protection associated with the Reactor Buildings. As shown on the enclosed sketches (provided in Enclosure 2), the suppression and detection adjacent to the raceways of concern provide an adequate level protection for the Reactor Core Isolation Cooling (RCIC) circuit to limit the possibility that a fire would require the use of the LPCI mode of operation to maintain hot shutdown.

NRC QUESTION 3:
In Enclosure 1 of CP&L letter to NRC dated August 31,1995, several documents and calculations are referenced which were not included as part of the submittal currently being        ;
evaluated. Therefore, to facilitate our review, we request copies of the following:                 ;
a) GE Calculation EAS-61-0989 b) Alternative Shutdown Capability Assessment Report for Brunswick Steam Electric Plant.
CP&L RESPONSE:
When CP&L submitted the August 31,1995, request for an exemption from the requirements of Sections Ill.G and Ill.L of 10 CFR 50, Appendix R, General Electric (GE) Calculation                ,
l   EAS-61-0989 encompassed those GE fuel types that were approved for use at the BSEP.                 >
;   Since submittal of the exemption request, CP&L has received NRC approval to load the GE13 fuel type. GE Calculation EAS-61-0989 is being updated to address the GE13 fuel type, and            l CP&L plans to submit a copy of GE Calculation EAS-61-0989 to the NRC by August 15,1997.
l   The Alternative Shutdown Capability Assessment (ASCA) Repor+. was submitted to the NRC in            1 1984. This report is a six volume report containing original database output and plant drawings      ,
at the time of the 1984 submittal. Volume 1 of the ASCA contained the shutdown methodology           l and detailed description of the individual fire areas and the fire protection features available in  !
the fire areas. A copy of Volume 1 of the ASCA Report is provided in Enclosure 3 to support         I the staffs review, since it contains the information referenced in this exemption request.          i
!   NRC QUESTION 4:
1 If not included as part of information requested in item 4, provide a more detailed description of l   fire areas RB-1 and RB-2. As a minimum, this description should: (a) describe the physical i   arrangement of the fire areas, (b) identify specific locations of post-fire shutdown equipment I
and cables (include components / cables associated with both the current RCIC approach and the proposed LPCI approach), (c) provide an analysis of fire hazards in these areas, (d) describe fire protection features (detection and suppression) provided for these areas, and (e) include simplified plant lay-out drawings, similar to those provided in the August 31,1995, submittal describing Fire Areas RB1-6 and RB2-6.
CP&L RESPONSE:
The ASCA Volume 1, Section 7, provides a detailed description and analysis of the hazards associated with the RB-1 and RB-2 fire areas which supported the approved 10 CFR 50, Appendix R, Section Ill.G.2, exemption for the Reactor Building configurations. Simplified plant i
layout sketches (five layout sketches) have been developed which reflect the general plant l
configuration for the areas acsociated with this exemption request (provided in Enclosure 2).
The generallocation of the RCIC circuits are shown on the sketches in addition to major components and raceways associated with the Residual Heat Removal (RHR) LPCI mode.

NRC QUESTION 5:
Provide a listing and description o the specific components that will be relied on to accomplish the proposed LPCI shutdown methodology. Include simplified drawings depicting major components and system flaw paths, and provide a detailed description of the proposed shutdown strategy.
CP&L RESPONSE:
A listing of RHR equipment for BSEP Unit No.1 and BSEP Unit No. 2 has been provided in l   Enclosures 4 and 5, respectively. Fire area locations have been identified for electrical l   components which could be affected by a fire. Fire area locations have not been identified for l   manual components which are not required to change state following the fire. Existing plant t
simplified flow diagrams have been provided in Enclosure 6 which identify the normal RHR configuration for shutdown cooling. Components not required for the LPCI mode have been identified in the comment section of Enclosures 4 and 5. Tha response to NRC Question 7 contains the shutdown actions required from the local control stations.
l NRC QUESTION 6:
Provide information which demonstrates that components associated with the proposed LPCI approach have been evaluated and found to be adequately protected from the effects of postulated fires in reactor building fire areas RB-1 and RB-2 where their use may be relied on to achieve and maintain post-fire safe shutdown conditions.
CP&L RESPONSE:
l   Sketches 1 through 5 in Enclosure 2 provide the generallayout of the Reactor Building associated with the location of RCIC circuits identified in the exemption request. The major Train B RHR components and raceways containing RHR circuits are also shown on these sketches. The Separation Zones shown on these sketches provide the approved Appendix R, Section Ill.G.2 separation between the Reactor Building North and South Fire Zones. The l   original ASCA submittal ihntified that local control of the Train B RHR components are located in the Reactor Building South Fire Zone and would be available to support shutdown from the local control stations. The RHR LPCI mode uses a subset of these components from the local control stations in the Reactor Building South Fire Zone. The original analysis of these components and cabling is maintained under the CP&L configuratirn control program to ensure future plant changes are reviewed and the original separation methodology is preserved.
NRC QUESTION 7:                                   ,
Provide a copy of the emergency or abnormal operating procedures developed to implement
:   the proposed LPCI approach in the event of fire in the identified locations of the reactor
;   building. For the purpose of our review, a draft version of this procedure would be acceptable.
i   if such procedures have not yet been developed, provide a detailed description of the shutdown methodology to be implemented by operators in response to fire in the identified locations.

The results    of   the  reexamination       and   reanalysis    of the Brunswick alternative shutdown        capability    can   be summarized as follows:
(1)   Separation between required safe shutdown circuits which meets the        specific requirements         of   Section III.G.2 of Appendix R to 10 CFR 50 presently exists in three of the fire areas reviewed.
(2)   Alternate shutdown capability           existed   or    could  be provided for 31 areas.
(3)   Ten exemptions from          the specific requirements of Section III.G.2 and III.G.3 of Appendix R to 10 CFR 50 are requested in twenty-two fire areas where existing fire protection features provide equivalent protection.
(4)   Associated     circuits      not    meeting     the separation requirements of Section III.G.2 of Appendix R to 10 CFR 50, and sharing a common power source with the shutdown equipment,   will be electrically protected from the post-fire shutdown circuits of concern by coordinated circuit breakers, fuses or similar devices.
w-      (5)  Associated      circuits      not    meeting     the separation requirements of Section III.G.2 of Appendix R to 10 CFR 50, and having a common enclosure will be electrically protected from the           post-fire shutdown circuit of concern (by circuit breakers, fuses or similar devices) and the proposed or existing fire area boundaries, fire retardant coatings       on      cables,    and special fire protection features on vertical raceways.
(6)   Associated     circuits      not    meeting     the separation requirements of Section III.G.2 of Appendix R to 10 CFR 50, and which could cause spurious operation adversely affecting the shutdown capability, have been adequately resolved by appropriate action pre- or post-fire.
1 (7)   One exemption from the specific requirements of Section III.J of Appendix R to 10 CFR 50 is requested for the East Yard where alternative emergency lighting provides equivalent lighting for safe shutdown requirements.

safe. shutdown systems and                                   their associated circuits at Brunswick Steam Electric Plant,                         Units 1 and 2 (BSEP), and the relationship of these features to the requirements of 10 CFR 50 Appendix R.[1]                                                                              ,
As a result of this evaluation, an alternative shutdown system is determined to be                   necessary                      to          achieve regulatory compliance in most plant areas.                    Conceptual designs for an alternative shutdown i
system and fire protection modifications are presented to outline                                                                              :

BSEP REVISION 1                         ASCA (2)   A fire hazards analysis of all fire areas identified in the plant.
In the report,     CP&L    identified    fire    areas and fire zones based on   the   inherent    fire   resistance      capability of existing plant structures. Fire areas     were designated as that portion of a building   that   is   separated    from   other      areas by boundaries 1
(walls, floors or roofs)      which   could    be upgraded to three hour fire boundaries with little or       no additional construction.       Fire zones were defined as     plant    areas not completely separated from adjacent zones by walls.       The combustible loadings for each fire area and fire zone were determined and the existing detection and suppression capabilities were quantified.
l The Appendix A report [1] identified 144 fire areas and zones
     --    in the two units at BSEP.      A majority of these areas consisted of
      ~~
individual rooms bounded by       walls with sufficient thicknesses to          .
qualify as rated barriers.        Areas not having a three-hour rating were found acceptable on      the   basis   of    a light fuel loading or lack of threat to    safety-related equipment and/or redundant safe shutdown equipment.       Principal    areas     of   concern   at the time included the   individual     Reactor    Buildings,      Radwaste Building, Control  Building,     Diesel     Generator    Building,     Service  Water Building and Augmented Off-Gas Building.
Barrier penetrations      considered     in    the   original analysis included doorways,     ventilation    ducts,     electrical    raceways and i          pipe chases. Penetrations of      concern    were upgraded to meet the Commission's requirements using the following methods:

The Commission's review of                                  the BSEP fire protection program resulted in the issuance of the Fire Protection Safety Evaluation og   Report    (FPSER)[ll)                on                November     22,   1977                                   Amendments  were  ;

shutdown is described in                                       this   report.       The principal focus of l
l     this report is on those areas in which modifications are required                                                l to meet Appendix R safe shutdown criteria or for which exemptions are requested.                                       An   important     result   of    this   effort  is the identification of safe snutdown modifications and fire protection modifications designed to further enhance the existing protection of    the  safe                            shutdown           capability.       These     modifications    are discussed in Sections 4 and                                       5.      The safe shutdown analysis was based on fire areas consistent                                        with guidance provided in Generic Letter 83-33[23).                                     As   in   the   BTP   9.5-1 analysis,[1] fire area boundaries    are                                   based   on   rated    barriers.        These  areas    are identified     in                                  Table   2.3-1    and   illustrated      in  Figures 2.3-1 through 2.3-42.

(1)  Review the fixed and transient cc.:bustibles either present or which may be introduced into the area in support of normal plant activities; (2)  Characterize the ignition potential; (3)  Identify those propagation control measures in use such as rated barriers, partial barriers, physical distance, ceiling height, and flame retardants which may inhibit the spread of a fire; (4)  Determine the capabilities of                the automatic detection and suppression systems; and (5)  Identify   those          features     which   may    be   required  to enhance protection within a given area.
Each step in this process is described in greater detail below.
2.5.1      Fixed Combustibles
      )         For   purposes   of   this         analysis,      fixed   combustibles    are ,
;       comprised of      exposed   electrical            cable    insulation, combustible liquids and other combustible material                  in   a fixed location in a fire area,,     The electrical cable portion of the fixed combustible loading was developed utilizing                plant cable and raceway drawings        !
in   conjunction     with   information             contained    in    a computerized conduit and cable schedule               (CASP). Combustibles associated with plant equipment and       all        other      in-situ    hazards were identified during field inspection.             As    described in this section, loadings 1
are calculated in a manner which ensures conservatism of the data presented.      The calculated           combustible loadings presented herein are expected to be larger than                the actual loading in the area by virtue of the conservatism in the calculations.

BSEP REVISION 0                               ASCA Philosophy The fundamental             philosophy      applied             to                       this            analysis was based on the:following considerations:
(1)     Accurate determinations of fixed combustible quantities can be made using plant drawings, computer data bases and field inspections.                                                                                                  ,
(2)     It         is   recognized that           fixed combustibles may be l                       characterized by different heats of combustion.                                                              Where      ;
l                       several different types of fuels were analyzed together I
as a group (as in the case of different cable types run in common trays), the value for the heat of combustion selected was based on that material present which had                                                                   '
the highest value.            As an example, the highest value for electrical           cables was determined to be 13,000 Btu /lb and is consistent with data reported in the literature.[20, 21, 22]
Conservatism i
s l               Conservatism             in  the  analysis              is      achieved                                 through        the
       ~N  following considerations:
(1)     The previously            calculated                  cable                                 tray    fill was determined using fill percentages based on a cross-                                                                     l sectional area method.               This results in a conservative l                       approach for the following reason:
Previous control and instrument cable calculations were completed using            the       cross-sectional area method,
,                       however, power cable was previously evaluated using a                                                                   '
diameter method.
This diameter method estimates the tray fill to be the ratio of the summation of cable                                                                     -
diameters to the tray width. For example, if three two                                                                  !
inch diameter cables were placed in a 12 inch wide by four inch high tray, the fill calculates to fifty percent as calculated below:
l l
diameter of summation             =   3 cables x 2 inches                                              =     50%        i tray width                                12 inches Using the cross-sectional method fill is calculated as 20%.          Using the previous example for a cross-sectional method the calculation is as follows:                                                                                   i cross-section area cables = 3.14 r 2 x 3 cables                                                             = 20%

The judgement that ignition          potential   is considered low is based on the availability of          high energy sources in the vicinity of exposed fixed     combustible       materials   and the ignitability of those   materials.        In      this   context,    combustible   materials contained    within   wraps,       behind     thermal   shields  or   inside enclosures such as closed         sumps, conduit, cabinets, tanks, etc.,
are excluded from consideration.
The ignition potential for         the   exposed combustibles is low if one or more of the following attributes apply:
(1)   Exposed electrical cable is either self-extinguishing, non-fire propagating or qualified to IEEE-STD-383[24]
or treated with a flame retardant coating;
.-           (2)   Lubricating oils in the area contained within closed             ,
i             sumps or in substantial equipment housings and have a
   '               high flash point
* no uninsulated hot surfaces (i.e.,
greater than 350 6F) exist within 20 feet of the sump);
(3)   Exposed fixed     combustibles are protected from floor-based   fires    by     plume impingement thermal shields composed of noncombustible materials; (4)   Area usage is          restricted     due   to  health   physics considerations; (5)   No uninsulated hot surfaces         (i.e., gecater than 350 F) exist within 20 feet of the exposed combustible.
2.5.4   Fire Propagation Control Measures Fire propagation is       a   concern    because   the spread of fire damage f ror its original       site could threaten redundant divisions of safe shutdown equipment.            Several   measures are available to control the propagation of fires.           These measures include:

The      standards which form the underlying basis for the design of these systems at BSEP are:                                             l (1)    NFPA-STD-72D-1975,               " Standard        for   the      Installation, Maintenance and Use of Proprietary Protective Signaling Systems"[25]

The detection system is designed to provide early warning of incipient fires     through     the     use       of ceiling-mounted ionization detectors. A    common    alarm     panel        mounted      in the Control Room provides audible and visual indication                of the fire zone in which an alarm may originate.       The supervision feature of the detection circuitry provides indication           of    faults       (e.g.,        loss of power, opens, shorts, etc.) in the system.
Automatic suppression         is     provided        in safety-related plant areas where significant exposure fires may develop as a result of plant activities. Such    areas       generally involve locations where combustible   materials      may      accumulate           in       support    of   work activities   (e.g.,      a  staging       area).         In     addition, automatic suppression    is   provided      to    protect       specific        hazards     and to protect ECCS systems       from    common       mode     failure       due to a fire.
Automatic suppression is        also      provided        in    certain areas where electrical cables for       redundant       safety-related divisions may be in close proximity to each other.
The sprinkler system design criteria is sufficient to ensure control of the anticipated hazards.                 The delivered water density capability of     the    BSEP   automatic          suppression        systems usually J

BSEP REVISION 0                                 ASCA 2.5.7     NFPA Codes and Standards The  fire   protection / prevention              features     at  BSEP   were designed and implemented             utilizing     the National Fire Protection Association (NFPA) codes as guidelines.                  At the time of design or implementation, the most recent                editions    of the applicable NFPA codes were utilized to achieve the required level of protection.
NFPA codes are revised on             a   periodic basis to keep abreast of the state-of-the-art in             fire     protection.      Recent changes in the codes allow         for   improvements        or    alternative approaches to achieving the required level of                protection and do not imply that the existing protection           is      inadequate.      Requiring the existing fire protection / prevention           features      at   BSEP   to   be reanalyzed against the     latest      published        editions     of   the   NFPA codes and T

Fire protection program and design features were implemented to meet the protection requirements      of     Appendix A to BTP 9.5-1.
The continued maintenance     of   those   systems and compliance with those specific code requirements ensures         that the high degree of fire protection, as originally      stipulated     by the Commission, is i l
maintained.
l Therefore,     all fire    protection   programs    and/or  systems implemented at BSEP under previous editions of the codes will not be updated to reflect subsequent editions.

criteria:
5 (1)   The    reactor          is            subtritical                   with         an effective multiplication factor (keff) of less than or equal to 0.99;                                                                                                           "

maintaining the reactor coolant level above the top of the active fuel; 5
(3)   Reactor decay heat is                               being            removed at         a ' rate

In    the      transition                    state, heat. removal exceeds heat generation allowing                     for            a      cooldown              of   the       plant. Cold l                          shutdown differs               from     transition                      in   that           the reactor coolant system temperature is reduced below 212 0F.

This definition     recognizes    that     electrical   cables may be damaged by a     fire. This   cable damage may prevent operation of safe shutdown components or       may   result     in maloperation of non-safe   shutdown    equipment    which     may    preclude   attaining  safe shutdown. The effects    of   spurious operation have been analyzed as follows:
(1)  Maloperation of safe shutdown equipment due to control circuit interlocks between safe shutdown circuits and other circuits; and (2)  Maloperation of equipment which is not defined as active or passive safe shutdown, but which could prevent the achievement of a safe shutdown function and thus has been included as required for safe shutdown.
3.3   Assumptions This   analysis   considers     the   effects     of  fire  on  plant
  ~
equipment and     identifies    methods    for    achieving safe shutdown.
The fundamental assumption made in this analysis is that a single fire occurs in any plant       area coincident with a complete 72-hour loss of off-site power.      However, off-site power is assumed to be present for those situations where availability of off-site power could adversely impact      safe   shutdown.         All equipment normally 1
present in    the   plant   is   assumed    to    be   functional at design 1 capability and may be lost only        as   a result of fire damage. No other   external    events,    accidents,     or   equipment   failures are assumed to occur in connection with either the postulated fire or l
through achieving a stable cold shutdown condition.

  .m (1)  The fire damage        occurs     throughout       the     area   under consideration.
(2)  The fire damage results in an unusable                      cable with regard to proper safe shutdown function.
(3)  The fire-damaged cable conductors will either short to other conductors in the same cable or conductors in other cables located in the same enclosure; or short to ground through the enclosure; or the conductor will separate causing an open circuit.
This analysis reflects       the    latest    position concerning hot shorts as expressed by    t..e   Staff    in   a me:aorandum to CP&L dated December 21,   1983.[9]        This   position     excludes       the following combinations   of   cable-to-cable       hot   shorts    based        on   the low likelihood of occurrence:
(1)  3-phase ac power circuit cable (4.16kV and 480V voltage levels);
   ''%      (2)   De-energized 2-vire double fused ungrounded dc power                          i
_T            cable (125V or 250V voltage level);
(3)   De-energized 2-wire double fused ungrounded dc control circuit caole (125V voltage level); and (4)   De-energized    2-wire     ungrounded     ac    power       or control circuits (120V ac).
3.3.1.2   Mechanical Component Damage Fire damage to valves,       piping, and noncombustible tubing is not assumed to    adversely     impact    their    ability      to function as pressure boundaries or as safe shutdown components.                Therefore, a fire   is  not  assumed    to    cause    a   valve   or    othec mechanical component to change    position      unless    the   fire also affects the electrical equi i runt or    circuit     associated     with the component.
In addition, it was    assumed      that    exposure    to     a fire will not prevent   the  manual   stroking       of     the   valve      following      fire
    'd extinguishment.

This assumption reflects the              fact        that nuclear power plant l        fires are   sufficiently     limited          in       magnitude     and    duration to l       preclude    the   potential    of    significanc              damage     to   mechanical 1
equipment. Damage which is      assumed              to   occur    as a result of a l
fire   would    involve   discoloration               and    other    such nuperficial l
manifestations     of   exposure     to       a       high    temperature      cxidizing environment. Since these effects would be localized e.nd of short l       duration,    mechanical     and      overall               structural     integrity    is considered not impaired.
3.3.1.3    Instrument Damage Instruments (e.g., resistance               temperature detectors (RTDs),
thermocouples, pressure t ansmitters                    and   flow transmitters) are assumed to    suffer    damage    in        a   manner        similar     to electrical i ' '%
_f cables. If these devices are         exposed to a fire, only associated cables   are    damaged. The     instrument              fluid    boundary remains undamaged.       Sight glasses     and        mechanically           linked tank-level indicators are assumed to be unaffected by fire.
3.3.1.4   Smoke and Toxic Gases This analysis     recognizes          that        smoke    and   corrosive gases generated    by   burning    materials               such      as    those    containing l       polyviny1 chlorides     may  pose       a       threat        to    personnel    safety.
Notwithstanding this      consideration,                the   relatively      short burn duration of the postulated fire is assumed to preclude the build-l       up of sufficient concentrations of               such gases to fail electrical I
and mechanical components.         Consequently, concentrations of such J

-s gases within fire      areas  and   deposition           of    chlorides on plant components are not considered in this analysis.
Postulated corrosive gas      build-up    from           a     fire in a small area and chloride deposition       within   a   general plant area would not be sufficient to adversely       affect plant equipment while safe shutdown is achieved and maintained.          This conclusica is further supported by the Commission in their analysis of the Browns Ferry fire as documented in NUREG-0050.[10]
3.3.2    Fire Duration and Brigade Activity The total fire brigade      commitment    to          a    fire is one hour.
This hour is broken down as follows:
(1)  30 minutes to respond and extinguish the fire.after its discovery
''h        (2)   30   minutes   to  assess   the    fire           damage     and restore suppression equipment following fire extinguishment 3.3.3    Inerted Drywell The BSEP drywell     is  inerted   during power operation within the following guidelines and therefore has not been analyzed:
(1)   The containment    atmosphere oxygen concentration shall be less than 4 percent by volume within 24 hours after thermal power is greater        than          15 percent        of rated thermal power.
(2)   The containment       atmosphere        concentration            may be deinerted beginning 24 hours prior to a scheduled reduction of thermal power to less than 15 percent of rated thermal power.
3.3.4    HVAC Requirements The -17 ft elevation (east side) of the Reactor Building and the diesel     generator   cells   are  cooled           with       the  normal HVAC equipment, or at least some portion of it.

(2)  Reactor Coolant Makeup.         Maintain the reactor vessel water above the top of the active fuel.
(3)  Decay Heat Removal. Remove the decay heat through cold
,,,               shutdown conditions.

(4)  Process Monitoring.       Provide     direct                    reading of safe shutdown process variables.
(5)   Support Functions. Provide    support                  to achieve all of the above performance goals.

l Two   de  motor-operated             valves      are    located    in     the  pump discharge line.          A    minimum-flow        bypass     line protects the RCIC pump from overheating under no-flow                 or low-flow conditions.          The minimum-flow bypass line maintains flow                   through the RCIC pump by diverting water to the suppression                 pool. The minimum-flow valve can  be   operated         automatically        or    manually.        When     operated automatically, the valve is controlled by a pressure switch which senses RCIC   pump        discharge       pressure      and    a   flow switch which
  -s    senses discharge flow.
3.5.2.2   High Pressure Coolant Injection System l            The High Pressure            Coolant      Injection (HPCI) System provides makeup water to the reactor to prevent overheating of the reactor fuel in the event         of    a    small     steam / water     leak in the primary
[       system. The system supplies             high     pressure water to the reactor i       vessel in sufficient quantities                to   keep     the core covered.       The l       principal components           of    the   HPCI     system     consist      of   a steam turbine,   which    drives         a   centrifugal        pump,    and   system valve controls and instrumentation.              The     system is designed to operate
!       Independent of ac power,             service      air, or external cooling water systems. HPCI can be operated automatically or manually from the Control Room,    or        it   can    be    initiated       manually    from a local Page 3-28

3.5.2.3    Automatic Depressurization System The purpose of        the   Automatic Depressurization System (ADS) is   to   provide     protection       against      overpressurization          of          the reactor vessel       and    to   enable     manual        depressurization       of the nuclear system.
Each unit has 11         safety / relief      valves (SRVs) which prevent reactor pressure vessel overpressurization.                     These are located on the four steam lines          between     the    reactor        vessel and the first J

main steam isolation valve.           Seven     of   these 11 valves have the l    automatic depressurization features.                Each   valve discharges to l    the suppression pool through          a   separate      line which enters at a point below the minimum water           level    of the pool. Figures 3.3-1 and 3.3-2 depict the major        components        in the ADS. Tables 3.5-9 through 3.5-12     identify     the     ADS    components    required for safe shutdown. The valves open      by mechanical self-actuation if there is excess pressure and       may    also      be operated remote-manually to control the pressure rise and depressurize the nuclear system.
All 11   safety / relief    valves       are   provided with individual control switches     for    remote-manual        operation    from the Control l    Room. Three   of   the    four    valves      which    do not have automatic
; -~ features can also be       controlled       from    the remote shutdown panel l
l located at the 20 foot elevation of the Reactor Building.
Each of the eleven SRVs associated with ADS is equipped with an air accumulator.      The    accumulators        ensure that there will be sufficient air to cycle       each     ADS     valve    five times or hold the
;    valve open if it     is    already     open,     in   the   event that the air supply to the ADS valve is unavailable.

When    the     control     switches are placed in the open position, a solenoid valve is energized, opening a pilot valve which    allows     steam   pressure       to   open   the   valve. The r
remaining four SRVs can also be actuated from the RTGB, and their

When operated remote-manually, the solenoid                   valves may be actuated at any nuclear system pressure.                However, sufficient steam pressure, approximately 100 psig,              must     be   present    to   overcome the main valve preload spring tension, or                  the   valve    will not open. The SRVs close once pressure drops below 50 psig.
In their     automatic          operating       mode,   the   ADS   valves open automatically when the HPCI system                  cannot make up inventory on a loss of coolant.        However, for           safe shutdown, the ADS valves are operated manually         to       provide     depressurization      of   the reactor vessel.
There are 11 vacuum              breaker      valves located in the drywell,

Following a SRV operation, the steam                   in the line condenses as it cools, creating a         vacuum       in     the   downcomer     tube. The vacuum l
breakers open to prevent water in the suppression pool from being drawn up into the downcomer tube.

coolant injection (LPCI)       mode     is    required         for reactor coolant level control during cold shutdown.            The TC function is performed           i by RHR in the suppression pool cooling mode of operation, and the                      i SDC function is performed by RHR in the shutdown cooling or low pressure coolant injection mode of operation.
The RHR   system     consists     of     two      essentially complete and i
:         independent loops, identified as train A                 and train B. Each loop    I is comprised of two pumps,        piping, valves, a heat exchanger, and associated instrumentation and controls.                   The arrangement of the valves and pipes for each        loop provides the flexibility required for the multiple functions performed by this system.
The   RHR  system     is   provided       with       manual    overrides  for 4

Reactor shutdown cooling and         torus      cooling are initiated by the l        plant operator.                                                                        !
In the LPCI mode      of   operation,        the      RHR system will start automatically in response        to    either     of two initiation signals:
(1) reactor vessel low low low level or (2) drywell high pressure coincident with reactor vessel low pressure.
The RHR pump can take       suction       from the suppression pool or from the reactor      vessel.       The    suppression          pool   is the water source for LPCI      and   sui-pression     pool        cooling modes operation, I
while the reactor      recirculation       loop        is   utilized for shutdown cooling operation.

l RHR Shutdown Cooling Function The shutdown cooling (SDC) function of RHR is used to remove decay    heat       once       reactor      vessel                    pressure       has  decreased      to l         approximately 125 psig.

L l         transfer to the Service Water System.                                       The water is then returned-             I l

During this mode of operation,                                  the isolation valves and the l         shutdown cooling         suction          valve            corresponding               to the operating pump are         opened  remote-manually.

l operation, only one pump per loop is permitted to operate (not an s_. ,   interlock but an administrative control).                                                                           l

For this analysis, one RHR                        pump per unit and its associated heat-exchanger are sufficient                     to          complete .the cooldown to cold                       >

RHR   instrumentation             provide            adequate                  monitoring   during   the I
I cooldown to cold shutdown.                  Logic                 circuitry of this mode of RHR operation is not essential for safe shutdown, since there will be ample time         for  operator          action.                       For     this   analysis of safe shutdown, the RHR loop               cross-tie                valve            is assumed to be closed l
with its associated breaker in the open position.

l      3.5.2.6   Service Water System The Service Water (SW)            System     performs two functions.                 The diesel generator cooling water (DGCW) function provides essential

cooling water    for   operation          of     the     diesel     generators.            The purpose   of  the    residual         heat      removal     cooling     water (RHRCW) function of the SW system is             to    supply water for cooling of the l      RHR pumps, area coolers and heat exchangers.
The Service Water      System         for    each     unit     consists of five service water pumps enclosed in              a water intake structure (common to Units 1 and    2),    and     associated lube water pumps, strainers, valves and controls.

BSEP s REVISION 0                         ASCA header consists of a group of service water pumps, parallel loads and   interconnecting    headers,         which     are   normally   operated independently.
Under   normal   operating      conditions,      three    SW  pun.ps (two operating, one standby) pr , vide       water to the conventional header while the remaining    two    SW   pumps      (one operating, one standby) provide water to the nuclear header.
The SW lube water     pumps     provide      water   to the nuclear and conventional SW pumps for bearing lubrication, seal injection and cooling water for the pump      motor       coolers. The lube water pumps normally take suction    from     either      the   nuclear or conventional header.
g-        Figures 3.3-11 and     3.3-12      depict     the major components and flow paths for the    SW   system     and     Tables 3.5-21 thicugh 3.5-26 identify the service water components which are required for safe shutdown.
For RHRCW, service water        is     delivered    to the tube side of the RHR heat exchangers     from     the     nuclear service water header.
For each unit, any one     of    the    five    SW pumps, and one RHR heat exchanger are   required    to    provide      cooling    water   for the RHR system.
For DGCW, the    Unit    1   and     2   emergency diesel generator's jacket water heat exchangers are supplied with cooling water from the nuclear headers from      Units     1    and 2 through normally closed motor-operated valves. The Unit       I   nuclear header is : e normal J

             - for diesel generators 3 and 4.                            The Unit 2 nuclear header is the normal supply for diesel                         generators       3   and   4 and the alternate supply for diesel generators 1 and 2.
The nuclear SW pumps, which supply the nuclear service water headers and are powered by                          the 4.16kV emergency buses, also have an. automatic starting capability.                            Upon loss of normal power, the diesel generators                    start       and     re-energize      the   emergency buses, which in      turn           enable            the   nuclear      SW   pumps    to        start. Once
              " tarted, the pumps                     will     continue      to    operate    until stopped by
              ;perator action or tripped                          by    pn: active      devices.           The nuclear service water pumps for                         each     unit    can supply cooling water for
   .-         the diesel generators of- either                            ar    both    units.          Each unit is provided with an                  opposite          unit    diesel     starting        signal to the nuclear service                water           pumps.       When     the   diesel generators of                    i eitaer unit automatically start,                            .the nuclear service water pumps for both units               also            start.       This    ensures     that an alternate, automatic water supply                         exists     for    the   diesel generator jacket water coolers in the event that there is loss of off-site power.
One operable service water pump is sufficient to satisfy the diesel       generator                      cooling       requirements        for         both     units simultaneously.                 For this           analysis,      the operation of one diesel l
generator per             unit              is  required      to    meet   the plant electrical demand.

The primary source of                  diesel    fuel          is the fuel oil storage l
tank. This tank              contains     sufficient        fuel             to operate all four l
diesel engines at full load                   for   seven days.                   This tank supplies four four-day               storage    tanks    located        in          the underground vault adjacent to the Diesel Generator Building.                                Two fuel oil transfer pumps provide transfer capability                     from each underground four-day
      --     storage tank             to     its   corresponding      diesel                 generator day tank.       1 Each   day      tank            contains      sufficient             fuel           to   operate  its       ;
corresponding diesel engine at                    full   load              for      a minimum of two hours. Existing local               transfer     switches allow operation of the fuel   oil      transfer            pumps    independently             of         the  Control Room, provided that ac                power   is    present    at          the corresponding local l
motor control center.
In addition to the diesel generators, the AC Emergency Power System consists of four                 4.16kV     emergency               buses (El, E2, E3 and E4) and four 480V emergency unit substations (ES, E6, E7 and E8).

Unit substations, consisting of transformers and switchgear, are         provided within the plant to step the voltage down to       480V    and supply loads at that voltage.
120V ac electrical     power    is   supplied for lighting, instruments and controls.
Each 480V substation is normally          fed from one of the 4.16kV emergency buses through a 4.16kV-to-480V, 1500kVA transformer and dual  primary / secondary    breakers.        Tie    breakers   are provided between the 480V     emergency     substations;      this allows feeding of one substation    from    another,     should    the   normal   feed  not be available. The    480V   emergency     unit    substations feed various p,   motor control centers which in         turn feed equipment necessary for safe shutdown of the units.
The   emergency    buses    El,    E2,   E5   and   E6   provide  power primarily to BSEP Unit 1, while Duses E3, E4, E7 and E8 primarily serve BSEP Unit 2.
The emergency buses are separated into two divisions.             Buses El, E3, E5 and E7 are Division         I; E2, E4, E6 and E8 are Division II. Cables    and   equipment     for   each    division    are physically separated to meet the original plant design criteria.             The diesel generators, 4.16kV emergency buses,         and 480V emergency buses are located in the Diesel      Generator     Building. The 4.16kV emergency buses are normally     fed   from    their    corresponding unit's 4.16kV auxiliary buses. Upon   loss    of   all off-site and unit auxiliary power, the emergency buses       are    powered    by the emergency diesel

The circuit     analysis     was    performed     based         on   the component's category. Components      that     were   required          to operate or change
,       position (active      safe     shutdown)     had   their         power    and control cables identified.        For components that were required to maintain their    normal   operating      position      (passive          safe    shutdown  or spurious operation), only the           control    cables which would change i
their position were identified.              Typical circuits which are not required for component operation are annunciator, computer, motor winding    heaters    and    external       monitoring          circuits    that  are
    -   electrically isolated from          the    electrical          circuits of concern.
    ''' The BSEP computer-based conduit            and cable raceway schedules were then used to identify the physical routings of individual cables.
The electrical     raceway      drawings     overlayed          with   the BSEP fire zones were marked up with the safe shutdown cable routes and safe shutdown equipment.        These    drawings     were         used to determine the physical location of        all   safe     shutdown equipment by specifying the fire zone     in     which   the    equipment       and cables are located.
These-fire zones were        later     combined    to produce fire areas for subsequent separation analysis.            This information was compiled to produce the     final     data   base    to   be   used         in   the   Appendix R separation analysi.'.

BSEP l     REVISION 0                           ASCA Using the functional       block     diagrams     and the safe shutdown equipment information,        the    Appendix     R   separation analysis was performed using the data         base    management system.          This analysis identified the safe shutdown components potentially damaged by an Appendix R fire in each         fire    area.       The analysis was done for 1
safe shutdown      from   both    the    Control     Room      and existing local   l control     stations.       The   functional      block      diagrams    were then  l I
evaluated for all safe        shutdown functions to identify deviations             I from the separation criteria of Appendix              R. Since there were no    l i
fire areas in     the    ESEP    analysis      that   are      considered free of   '
intervening combustibles         (fixed     or   transient),        all electrical safe shutdown     equipment      in   a    given    fire     area was considered
  -, failed in the most damaging manner.
  --       The    next   step    was   to    develop     options      to   resolve   the identified deviations.           These     options    included,       but were not  ;

This    process identified those       l safe    shutdown      components      which      required       modifications    to facilitate     safe    shutdown     operation       from     the    Control   Room, existing remote shutdown panels, or             local control stations.         The existing remote shutdown         locations      are   described in Subsection 6.2.2 where they are identified as alternative control stations.
The final product of        this     analysis identified all the fire areas at.BSEP     which     require     alternative shutdown from existing control stations (see        Section     4   for    a detailed compilation of i

Electrical circuit fault                    protection was originally designed
(                  to provide protection for plant electric circuits through the use l                  of   protective          relaying,       circuit         breakers,           and          fuses. This protective equipment was designed                      and applied to ensure adequate protection of all electrical distribution equipment from electric l

electrical circuit and thus                   will     prevent the propagation of the
!                  fault to other portions of the electrical system.
An        integral      part     of         the       original         electrical           system protection was           the    proper        coordination         of        all these devices.
Such coordination ensures that                     the      protective device nearest to the fault          operates     prior       to     the      operation           of any " upstream" devices, and           limits      interruption          of    electrical                 service   to a minimum amount            of    equipment.             These      design practices provide I
reasonable assurance that                most       circuits       of concern, associated with safe shutdown             circuits        by     common      power supplies, will be sufficiently           protected      to      ensure        that   fire            damage      does not

Three assumptions were employed in this review:
(1)  No' single failure criteria was applied to electrical protection devices.               Electrical protection devices are assumed to operate properly in accordance to their corresponding      time-current                                                        characteristics, unless their failure is directly attributable to a fire.
(2)  Only one electrical fault at any given time was assumed to affect a common power supply feeder branch. The largest load side feeder circuit breaker or fuse was used for that purpose and coordination verified against
                              -s                                                                                                the line side protection.                                                            Electrical faults may be
                                                           ;                                                                    considered bolted phase-to-phase or phase-to-ground.
                                  ~/
(3)  Loss of electrical power (either motive or control) to passive safe shutdown devices (as defined in Section 2) was not considered detrimental to safe shutdown since these devices were assumed to be in their normal position or status pre-fire and thus fail safe or "as is". Loss of electrical power (either motive or control power)     to passive                                                       safe shutdown devices, by definition, would not have an impact on safe shutdown capability by spurious operations unless that condition had been clearly identified in the safe shutdown                                                                                                                    :

Consideration           will be given to incorporating direction in post-fire shutdown procedures to clear buses of non-safe shutdown loads                     where    simultaneous sustained circuit faults have the potential of affecting a safe shutdown power supply.
Upon           incorporation       of         these         changes,                proper    circuit coordination will exist at BSEP, thereby eliminating all circuits i

3.5.4.2               Associated Circuits by Spurious Operations This analysis              identified         the    potential spurious operation candidates                    and  placed    them     into       one        of            the 'following           two categories:
(1)         Spurious operation candidates which could affect proper

For other cases,         no       redundant device was used because the prevention of                    a   loss    of      coolant           could               be assured by the

Propagation within the same fire                                                    area is ameliorated by the j,                  IEEE-383 features                             of         the         cable             insulation- used                        on power and control circuits.

Since conduit is totally enclosed along its route, fire

         . Process instrumentation / control loops                                  originate' in a panel which contains the de power       supply for the instrumentation loop.
This panel is fed by     120V   ac      power circuits which-also present the potential    for   fire   damage           resulting                           in   a 120V ac power  ,

conductor coming-in contact       with            an            instrumentation loop.               The concern is that fire     damage    may propagate into instrument loops in the form of a flame front or fault current.
The design   features    of    an            instrumentation                        panel provide several barriers which greatly reduce the likelihood of a 120V ac power circuit coming     in   contact             with                an instrumentation loop.
First, the entire enclosure       is       grounded.                              This would cause the   ;
local fuse in the power      circuit to blow should the fire-damaged, s 120V ac wire come     in  contact       with                either the enclosure or any                  ,
4 metal-encased device inside the            cabinet.                            Given the far greater surface area of grounded enclosure                   to           cable, there is a greater             i potential for the fire-damaged          circuit                       to          contact a portion of the metal enclosure than another wire located inside the cabinet.
The next barrier to      damage,             whicn                 would inhibit the fire-damaged 120V ac    power    cable    from contacting an instrumentation loop, is    the  metal   shield    enclosing                          all instrumentation loop l
conductors which     run  external         to            the instrumentation cabinet.
Similar to the enclosure,      this        metal                  shield is grounded at one end of the instrument     loop    and         would,                     in all likelihood, also l
blow the local 120V ac panel       fuse               in the case of a fire-induced fault.

BSEP m      REVISION 0                                         ASCA For the reasons                   delineated      above,          the       potential for fire l
l damage inside an instrumentation panel resulting in 120V ac being impressed directly on an instrumentation loop, is sufficiently small as to be neglected.
,                 Raceways             routed           throughout            the     plant               which  contain instrumentation loop conductors                        are          dedicated           to that service.
They contain nothing                    but. instrumentation               loop circuits and are
!           completely enclosed.                        Because    of         this    restriction,              the only i
cable-to-cable              faults          which    could          induce      fire damage-related fault currents in the subject loop would be other instrumentation loops. Because of the small                     currents used in these circuits (in the range of 4-20 ma or 10-50 ma), it would require mcny multiple
      -3    faults on a single              conductor            to generate sufficient currents to 1
     '#     produce an ignition                 source        in   some          other     part            of the plant.
Instrumentation loop power supplies typically will not allow much more than the              design          maximum    for         the    loop        for the following reasons:
(1)   First, the step-down transformer which feeds this power supply has inherently a                        large impedance because of the small conductors used on the secondary winding.
(2)   The secondary                       side    of           the     transformer usually incorporates a current-limiting resistance to reduce "in rush" currents when the power supply is initially turned on.
(3)   Usually the regulator portion of the power supply incorporates a " current sense" resistor which controls electronics which prevent an excessive current from j                       being produced by the output stage of the power supply.

I i     These multiple      faults   would    have       to   take    place   through the
(     grounded shield which encloses         each instrumentation loop pair of l

The potential for      multiple         faults   resulting in a credible 1
ignition source is best illustrated with an example.                  Suppose ten l     instrumentation loops operating at              full   scale (50 ma each) were l

g (.0068) = 1.7 milliwatts (based on #18 copper wire).                  This energy level can best be put into perspective by comparing it to a cable insulation damage study performed by Factory Mutual Research.[12]
i Table X of the Factory       Mutual Research report shows that piloted i
i      ignition,    in   natural   air    flow,       requires     integrated energies ranging from 420 KJ/M 2 to      1360    KJ/M2         In order to reach these integrated    energy     levels,     the        previously      calculated   1.7 millivatts would have       to   be   applied        for   a   time ranging from approximately 67 hours to 217        hours.        Clearly, since these times are    so  long,   the    deposited          energy   will    dissipate   before sufficient     integrated   energy       levels       are    reached   to  cause ignition.

  ,_   REVISION 0                          ASCA Based on the large number of independent faults required and the fact that these faults would also have to occur through metal l      shields, it is    likely  that      this    situation    does not present a credible common-enclosure ignition          source    remote from the point l
of the presumed fire damage.
Remotely located devices are, primarily, process measurement transmitters which control       the    instrumentation loop currents to some    value  proportional      to     the     measured    variable. The instrumentation cables routed to         these devices are enclosed over      l their entire path in the raceways discussed previously.              Once the cable enters the    electrical      enclosure     which    forms part of the transmitter, it is again protected by a grounded metal enclosure.
   -s  This enclosure protects the loop conductors from coming in direct
   '/  contact    with  high-energy     electrical      conductors.      Since most transducers are powered     by     the   current     (4-20   ma) which flows through the instrumentation loop, there            is no mechanism by which a high-energy hot short     could      take    place inside the transducer enclosure.
In  summary,   the   only       locations      in   the  plant   where instrumentation circuits are exposed          to   fire damage which could induce currents in excess      of    the    normal   4-20 ma are the fixed routed raceways, control panels        and    instrumentation racks. The currents which could be     induced      by   a fire affecting a raceway, have been shown to be    too     small    to   be   of concern. Also, the l       barriers inherent in the      instrumentation       rack and control panel i

3.6  Conclusion This   section     described        the    process      used  to     identify deviations from the safe and alternative shutdown requirements of Appendix R. Th. sections        which   follow     present the results of this analysi , summarize the           modifications proposed, and contain exemption applications where Section III.G requirements cannot be met. The nature of      these       modifications are, for the most part, g  refinements to the      existing       alternative shutdown capability and

generally    involve    provision       of   additional      electrical circuit isolation devices.      The     principal     conclusion to be derived from this   assessment    is     that     existing   plant      alternative shutdown features provide a substantial           amount      of protection to the safe shutdown capability as specified by Appendix R.

l (1)  An   alternative           shutdown       approach        relying          on remote operation of equipment               from dedicated alternative safe shutdown control stations and local operator actions as a   redundant          method     for     Control        Room        control           on a selective component basis; (2)  Exemptions based on either                    existing              protection                or proposed modifications; or (3)  Combinations of the above options.
For each safe          shutdown      system,     the proposed modifications for      achieving     safe        shutdown     are     described         in       Table     4.1-1.

Section 6 presents the alternative shutdown methods for achieving l         each prescribed safe shutdown performance                        goal. Sections 5 and 7 l contain the proposed fire               protection modifications and exemption                                   !

4.3      Areas Requiring Alternative Shutdown A fire in selected           fire     areas     may preclude achievement of many safe       shutdown          functions     when     analyzed        according           to the l
criteria of Appendix R.               The     fire areas below, with the affected l

5.1  Introduction This   section    describes    the      various     fire    protection modifications proposed for     fire   areas    containing safe shutdown equipment.      These  modifications    meet    one   of   the    following criteria:                                                                    )

  .       .;            requirements.
l Automatic suppression system      modifications are described in two sections. Subsection   5.2 describes proposed automatic water suppression system modifications and the areas where installation is proposed. Subsection 5.3   includes a description of the Halon suppression system proposed to be      installed in Fire Area DG-1 in support of an exemption application.
Fire  protection   modifications       to  upgrade     fire    barrier penetrations are discussed in Subsections 5.4 through 5.7.             These modifications are intended to     provide a fire rating commensurate with   the  anticipated    equivalent    fire   severity     of   areas   of concern.      In  general,    these     requirements     are    applied   to

A    description         of        fire     suppression               systems             to meet the requirements of Appendix R[1]                    is   included                in this section.           As discussed in Section III.G.2(b) and                       (c) of Appendix R, fire area suppression in the area is                    a  required          feature in order to meet the  separation           requirements           between         redundant                  safe  shutdown trains.        In conformance with              the requirements of Section III.G.1 of Appendix R, CP&L           proposes           to   provide suppression systems in the following BSEP areas:                                                                                   ,
(1)         5 ft Elevation of the Reactor Building Unit 1 A    single line of              closed-head sprinklers will be installed above the-HPCI Room running from east to west bounded by the Reactor Building wall and the dryvell.
This suppression system, in conjunction with 20 feet of horizontal separation with negligible quantities of exposed     fixed            intervening             combustibles                in    the separation zone, will provide reasonable assurance that at least one safe shutdown train will remain free of fire damage.                                                                              1 (2)         20 ft Elevation of the Reactor Building Unit 1                                            ;
i A   single line of              closed-head sprinklers will be installed running east to                        vest            from the Reactor Building wall to the drywell.                            This fire suppression system,   in conjunction with 20 feet of horizontal separation with negligible exposed fixed intervening combustibles between               the         redundant safe shutdown trains, will provide compliance with the separation requirements of Appendix R.

Conduits for the power and control cables for the diesel generator exhaust fans where routed.through DG-16 will be provided with a three-hour-rated enclosure.
(9)   All exposed cables within the east separation zone on the 50 ft elevation of Reactor Building Unit 1 and Unit 2 will be provided with a one-hour-rated enclosure.
The material and     specific     design   to   be used in enclosing raceways will not    be   specified     until   the detailed engineering phase. The design will   consider fire protection requirements as well as other issues affecting        reactor safety such as structural loads and equipment qualification.
5.9  Fire Stops An issue of concern      is   the   prevention of fire propagation between redundant safe shutdown        trains.      In lieu of Appendix R separation features in the       Reactor Buildings, a configuration is 9s,j    employed    relying  upon   a    combination    of   physical separation, automatic suppression and detection, and rated fire barriers.          To inhibit fire propagation      downward    along    exposed vertical cable trays and across separation zones, fire stops are proposed.
Vertical    trays    penetrating      floor     slabs  at  different elevations of the Reactor      Buildings    will utilize these stops at either the top or the bottom       of   the slab in lieu of penetration seals. Horizontal cable    trays    traversing the west central zone of the 50 ft    elevation   of    the   Reactor    Buildings will also be equipped with stops.

: 6. ALTERNATIVE SHUTDOWN CAPABILITY 6.1    Introduction For the fire areas where the requirements of Section III.G.2 cannot be met, CP&L will expand its existing alternative shutdown capability      in     ac.nordance       with      Section            III.G.3   to   meet     the performance goals          of     Section        III.L        to      Appendix   R.[1]     This section      describes      the     alternative            shutdown        capability     to be implemented in order to achi' eve compliance at BSEP.
The proposed alternative                shutdown              capability   for the safe s   shutdown areas utilizes             the     safe      shutdown systems described in i
            -     Subsection 3.5 of this report                 and the modifications described in Section 4 to the          existir.g      remote       shutdown system to ensure the ability to meet Appendix R               performance goals. The present remote shutdown capability already provides the                             ability to meet.much of l                 the safe shutdown performance                 goals        at BSEP.        The modifications proposed in      this      report       are      directed            primarily   at providing enhanced circuit          isolation        for     the         remote shutdown capability presently installed at BSEP.
l All    equipment         and     cables        associated           with    alternative shutdown capability will             be      separated              from. the   fire areas of concern in accordance             with     the      requirements of Section III.G.2 except for the limited number                  of    cases which are the subject of exemption requests.             These     exemption               requests   are provided in
;                  Section 7.

original design by      installing    each   4.16kV     bus and each diesel

generator in a separate room.
The   alternative     control    locations     will     be   electrically isolated using manual      control    switches, relays, breakers, fuse-disconnect   switches     or  coordinated      fuses. This     will provide isolation for all     cables   which    could     affect     the operation of alternative    shutdown    components    as    a   result     of fire-induced failures (open circuits,      short    circuits     or shorts to grounds).
Circuit isolation capability will        be provided for control, power and   instrumentation     cables,   as   required,      to    ensure     that no electrical connection will      exist    after manual isolation between the alternative shutdown circuits        and     those circuits that could v                                   Page 6-4

6.2.2               Control Room Alternative Control Station The Control Room alternative                 control                  station is located on the 49 ft elevation of                        the   Control     Building.                          The Control Room i
occupies the majority of this Control Building location.
This control location remains                  operable, to some degree, for any fire located outside this fire area.
Some of the               circuit   modifications              described                            in Section 4 were made                        to ensure    safe   shutdown       system                    operation from the Control Room and the                         descriptions     are           included in Table 6.2-1.
Page 6-6

BSEP REVISION 0                        ASCA These modifications justify      the   Control  Room as an alternative control station. However,   fires    may result in sufficient cable damage to force    the  use   of   the designated alternative control stations described in Subsection 6.2.1.
The Control Room is    the   preferred location for the control operations which are required.
6.3   Alternative Shutdown Method The  alternative   shutdown     method   at    BSEP    involves      the following categories of alternative shutdown activities:
(1)  Alternative    shutdown       activities       at    designated alternative control        stations     located outside the Control Room.
(2)  Alternative shutdown activities      which are accomplished inside the Control Room.
    'N       (3)  Manual alternative shutdown activities which occur at s-              equipment that requires manual operation because of fire damage to the electrical operators or cables for the component.
The following discussions of the alternative shutdown method are based on the guidelines listed below:
(1)  Overall alternative        shutdown     activities         will be coordinated either by the unit operator in the Control Room or by the operator manning the remote shutdown panel section of the RCIC and RHR alternative control station.
(2)  Whenever possible, the safe shutdown activities will be controlled from the Control Room.               Sometimes this involves alternative shutdown activities taking place in the Control Room.
l l            (3)  Normal safe shutdown      activities    are  not discussed in j                 this report.

(4)     Because spurious operation candidates were resolved, in some cases, by opening         the associated circuit breaker, the following safe shutdown valves must. have their breakers closed prior to use:
(a)   Unit 1:    (1-Ell-F008 or 1-Ell-F009) 1-Ell-F006A, 1-Ell-F006B, 1-Ell-F006C and 1-Ell-F006D.
(b)   Unit 2:    (2-Ell-F008 or 2-Ell-F009) 2-Ell-F006A, 2-Ell-F006B, 2-Ell-F006C and 2-Ell-F006D.
Due to the large number           of fire areas for which alternative shutdown is       provided,    it    was   determined                       that an area-by-area discussion of the safe         shutdown      method             would be cumbersome and                              -
would     not   clearly     present      the     important                              features             of  the alternative shutdown capability.              Table 6.2-1 provides a summary of the alternative         control    methods     which                     will be utilized for each of the BSEP fire areas.              A sample entry for Table 6.2-1 is
     ,e S provided on the following page.
To utilize Table 6.2-1,           the alternative shutdown activities described below must first           be   reviewed.                     For the given sample,                        ;
Subsection 6.3.6        would    be   considered             for                the                portion of the alternative       shutdown     method      addressing                           the                SDC     function.
Similarly, Subsection 6.3.7 addresses the remaining safe shutdown                                                    ,
function which       requires     control     of     the designated alternative t
control stations for EPS.
               . Note for this sample,         the   TC    and             DGCW functions would be                             ;
fulfilled      from    the   Control     Room.           Consequently,                                    the normal l operating procedures         and    equipment     would                     be              used.            The PMI function would also be unaffected by a fire.

The RHR system valves are         controlled      from the RCIC and RHR alternative control station.          The    operator at this station will realign valves to put     the     RHR    system into the suppression pool cooling mode. This is accomplished by local control switches and indicating lights located at the           individual MCC cubicles for the RHR safe shutdown valves.        This    MCC   is part of the RCIC and RHR alternative control station.
The   RHR   pump  is   controlled        from   its     respective 4.16kV emergency switchgear alternative           control   station. The operator at the 4.16kV    emergency      switchgear     alternative control station
    ~s   will close the RHR pump breaker once           he is requested to do so by
  ~
the coordinating operator.        This action will not take place until the operator at    the  RCIC      and    RHR   alternative control station verifies that the RHR     system      is    aligned to start torus cooling operation.
The   torus   cooling      function     will   be    initiated following isolation of the    reactor      vessel. Once   this     function has been initiated, operator action is not           required until the decision is made to change the RHR operating mode to shutdown cooling.
Diagnostic instrumentation          required    to     support the proper operation of the    TC   function       is   located     at   the RCIC and RHR alternative control station.

The shutdown cooling function is provided by one         train of RHR in the shutdown cooling mode.
The  RCIC   and    RHR   alternative     control    station   provides l
indication and control capability         for establishing the necessary valve alignment for SDC.        The   shutdown    cooling mode of RHR can i          start as soon as     the   reactor pressure drops below approximately 1
l          125 psig.
l                The  operator     activities    required      to   initiate   the   SDC function consist of realigning the RHR system valves to terminate l

realignment begins, the RHR pump         will be tripped by the operator l
manning the emergency 4.16kV        alternative control stations.        Once ,
the   pump  is   restarted,     the   only    subsequent     operator action l
,          required will be throttling service water flow or RHR flow to the l
l          RHR heat exchanger to control the reactor cooldown rate,                       j l
During the subsequent      cooldown,     the operator will maintain reactor water level by shifting         the RHR pump suction between the       l reactor vessel and the       torus   to   allow injection of torus water directly into the vessel       through    the   RHR    loop. Reactor level instrumentation located at the        RCIC    and RHR alternative control l
