l FOR INFORMATION ONLY CONTROL OF PLANT HAZARDS BARRIERS I SAN ON0FRE UNITS 2 AND 3 PROGRAM DESCRIPTION I. PROGRAM

SUMMARY

l As part of the response to problems identified in late 1993 concerning control I of watertight doors, Edison initiated development of a program to control I design basis hazards barriers at San Onofre Nuclear Generating Station (SONGS)

Units 2 and 3. An interim program was established to control hazards barriers i in accordance with 10 CFR 50.59.

1 A long term program is under development, and is expected to be in place during the Unit 2 Cycle 9 refueling outage currently scheduled for November 1996. An amendment request is being submitted to the NRC to add the long term program for the control of barriers to the administrative technical specifications. The program will provide controls for plant barriers which protect structures, systems, and components from 1) missiles from internal sources and adjacent buildings, 2) flooding from tsunami, internal sources, and adjacent buildings, and 3) environmental hazards (such as steam and l radiation). The normal configuration of these plant barriers is closed and l functional. Barrier impairments will be allowed if:

i

a. The average annual cumulative risk of fuel damage from design basis events attributable to barrier impairments does not exceed l.0E-6. Barrier allowed outage times are based on typical times l needed to restore the barrier, implement alternate barriers, l remove the hazard (s), or implement compensatory measures. Barrier allowed outage times with compensatory measures in place are based on typical times needed to perform plant maintenance, or l b. Justified by a 10CFR50.59 safety evaluation, t

or

c. The protected equipment is declared IN0PERABLE, or is not required to l be OPERABLE.

l l The long term program will be in the form of a Licensee Controlled l Specification (LCS). This document provides a description of the background, j scope, methodology and processes used in the development of the LCS.

L p 1 / 19

FOR INFORMATION ONLY II. BACKGROUND A. LICENSEE EVENT REPORT In September 1993, certain watertight doors, hatches, and penetration seals were removed from the Unit 3 Safety Equipment Building (SE) to support pre-outage construction activities. The watertight doors, hatches, and penetration seals are part of the barriers separating redundant trains of safety related equipment. An NRC inspector noticed this configuration and questioned whether these barriers, with the doors, hatches, and seals open, were able to perform their design functions and whether the effects of design basis events had been fully evaluated.

In response to the NRC inspector inquiry, Edison initiated an investigation of the expected plant response to design basis events with the altered barrier configuration. An engineering evaluation concluded that potential design basis scenarios existed which could have adversely affected the ability to achieve and maintain cold shutdown. At this ,

point, Edison restored all SE barriers to their original configurations. 1 Edison reported the Unit 3 condition to the NRC in Licensee Event Report 2-93-009 dated November 24, 1993. Subsequently, Edison committed to I maintain interim administrative controls for the Units 2 and 3 plant l barrier configurations, in accordance with 10 CFR 50.59 requirements, '

until a long term barrier control program was established.

B. INTERIM BARRIER CONTROL PROGRAM The interim program controls barriers which protect against design basis fires, missiles (internal and external), floods (internal and external),

unmonitored radiological releases, high energy line breaks, as well as maintaining ventilation / isolation boundaries, security boundaries, and environmental qualification of plant safety systems. All barriers are required to be closed and functional during normal operation for both Units 2 and 3, consistent with the " intact" barrier configuration assumed by the plant hazards analyses. Any departure from this configuration requires a 50.59 evaluation to justify the plant change.

When it is desired to have a barrier opened for planned activities, the requesting work group must request Fire Protection Engineering (FPE) to l initiate an " Impairment Form - Fire Rated Assembly" (IFFRA), then request the Nuclear Engineering Design Organization (NED0) to perform a 50.59 Safety Evaluation. Until FPE is notified by NEDO that the l evaluation allows the barrier to be open and any associated compensatory i measures are instituted, the associated IFFRA will not be activated.

1 p 2 / 19

1 i

l FOR INFORMATION ONLY When a barrier is discovered to be potentially inoperable, an unanticipated IFFRA and an Action Request (AR) are generated. For these ARs, NEDO performs an operability assessment to identify any non-fire barrier functions, and determine the compensatory measures required until the barrier is restored.

NED0 maintains a tracking system of all barriers which have been evaluated and are allowed to be impaired. In order to maintain the -

ability to perform evaluations which reflect the exact plant configuration and the potential for interactive effects associated with multiple barrier openings, FPE notifies NEDO when all IFFRAs affecting the functionality of a barrier have been terminated. This, in turn, means that a new barrier evaluation request and IFFRA must be generated each time a barrier is required to be opened - regardless of whether the barrier has been previously evaluated by NEDO.

This process imposes an undesirable burden on Operations, Maintenance, NED0 and FPE. For Operations and Maintenance, there is an undesirable but inherent delay for any activity, including corrective maintenance, that requires removing hatches or blocking doors (e.g., routing of compressed air hoses and welding cables, door repair, etc.). For NED0 and FPE, the tracking and evaluation process is very manpower intensive, requiring an additional 5 full time engineers.

C. LONG TERM BARRIER CONTROL PROGRAM TEAM In January 1994, a team was formed to develop a long term program for control of plant hazards barriers. The team includes stakeholders from Operations, Fire Protection Engineering, Maintenance, Construction, Nuclear Licensing, Nuclear Oversight, and NED0 (Civil, Environmental Qualification, and Integrated Plant Review Engineers).

A key goal of the team is to identify appropriate control measures for each hazard barrier and eliminate the need to evaluate hazard barrier

! impairments on a case-by-case basis. The strategy to address this concern for the long term program is to implement a Licensee Controlled Specification (LCS), in which barrier functionality would be decoupled from equipment operability for a limited time. This is similar to the decoupling of safety system operability from that of some support systems (e.g., fire doors and snubbers) in the existing Technical Specifications, and relocation of these requirements to an LCS.

FOR INFORNATION ONLY III. SCOPE A. EVENTS i

The long term barrier control program addresses passive devices required

! to mitigate and protect the plant against the consequences of specific

! design basis hazard events defined in the Updated Final Safety Analysis Report (UFSAR).

l The long term barrier control program does not address any events covered by existing control programs. Specific barriers covered by existing control programs include fire barriers (via FPE impairment l process), security barriers (via the Work Authorization Request (WAR) l process), control room and fuel handling building ventilation boundaries l (via Technical Specifications and procedural controls), other

ventilation boundaries (via Equipment Control), high energy line break

! whip restraints or impingement barriers (via the WAR process), and containment (via Technical Specifications). Tornado missiles and external flooding (probable maximum precipitation) events are also excluded, since they are covered by the severe weather Abnormal Operating Instruction (A01). (For severe weather events, warnings are received from the Energy Control Center with sufficient prior notice to permit barrier closing before a hazard to the plant can occur.)

l For the long term barrier control program, each barrier in a given l building was evaluated for the remaining hazards:

l e Missiles from internal sources and adjacent buildings.

l

• Flooding from tsunami, internal sources, and adjacent buildings.

• Environmental Qualification (EQ) hazards such as steam and l radiation from internal sources and adjacent buildings.

l B. BUILDINGS l Buildings containing safety related equipment or equipment that can l affect safety related equipment are included in the long term barrier l control program. The areas controlled for each unit include unit-specific and common areas. The unit-specific areas include the Penetration Building (PE), Fuel Handling Building (FH), Safety Equipment Building (SE), Diesel Generator Building (DG), and Tank Building (TK).

The common areas include the Control and Radwaste areas of the Auxiliary Building (AC and AR), and the portion of the Turbine Buildings (TB) containing the Saltwater Cooling Pump Rooms and the Saltwater Cooling Piping Tunnel. The Containment Building is not included in the long term barrier control program, because it is already controlled by specific Technical Specifications.

1 The program considers the effects of event occurrence during all plant Modes and the defueled condition.

IV. METHODOLOGY A. OVERVIEW The long term program is based on the existing deterministic analyses of each hazard, which assume all barriers normally closed and functional.

The existing design basis analyses were reviewed to identify the credible hazards for each area, associated plant barriers, potential alternate barriers, and compensatory measures. In some cases (e.g.,

missiles, high energy line breaks), it was necessary to reconstitute portions of the analyses using more conservative methodology to adequately evaluate the effects of specific barrier openings, such as i Barriers between a hazard source area and adjacent doors and hatches.

areas were identified as EQ/ missile significant unless the conditions resulting from propagation through the barrier were defined by design calculation and determined to be acceptable. Alternate barriers were limited to those suitable for the respective hazards under design-basis conditions. The hazards, applicable barriers, protected . systems, potential alternate barriers, and compensatory measures were then summarized in tables, based on the Fire Area summaries and drawings.

t Impairment of the detern:inistic hazard barriers will be permitted only l within an allowed out of service time (A0T). The A0Ts for hazard i barriers were determined from actual plant need (e.g., minimum barrier repair time, and major eglipment overhaul duration). The average annual cumulative risk from these barrier A0Ts was then evaluated using the SONGS 2/3 Individual Plant Examination (IPE) and Shutdown Probabilistic Risk Assessment (PRA) models, to verify that the incremental risk of fuel damage was maintained to acceptable levels.

B. MISSILES i Plant missile hazards and associated protection features are described l in UFSAR Section 3.5. Missiles are postulated from normally operating l rotating equipment and high energy piping systems. Review of the design i basis analyses indicated that they had two simplifications which were i not conservative for conditions in which barriers may be impaired: a)

Standby-designated equipment and safety related equipmen+ had been i' generically excluded as not "normally running"; and b) Equipment and systems located outside safety related areas (e.g., roof mounted p 5 / 19 l

- - - - = . - - -

FOR INFORMATION ONLY ventilation (HVAC) units, or turbine building pumps and valves) had been generically excluded based on intervening barrier thickness.

To address these concerns, walkdowns were performed to identify the population of potential missiles which have interactions with doors, hatches, and removable block walls that protect safety related equipment. The walkdowns identified a small number of additional postulated missile sources and determined which missile sources for each unit have potential interactions with barrier openings. These missiles will be evaluated for residual energy (e.g., after penetrating the equipment casing) in supplements to the applicable design calculations.

Pending completion of the calculation supplements, securing of the affected equipment or piping will be specified as a compensatory measure for impairment of the applicable barrier (e.g., opening of the door, hatch, or removable block wall).

Missile hazards apply in all plant modes.

C. EQ-FLOODING Plant flooding from tsunami and the associated protection features are described in UFSAR Section 2.4.6. The design basis tsunami is

, postulated to result from a vertical displacement of the sla floor at the Hypothesized Offshore Zone of Deformation, 5 miles from the plant.

The analyses assume concurrent high tide, storm surge, and wind-driven l l waves in addition to run-up from the tsunami. Alternate barriers are 1 specified for the flood height of this design basis combined event.

Compensatory measures are specified for actual tide conditions plus tsunami run-up only. Operator action is not credited, because the flood source (ocean) is generally unisolable for the duration of the event.

l Plant flooding from internal hazards and the associated protection features are described in UFSAR Section 3.4. Flooding is postulated as  !

a result of fire suppression system operation, tank wall failures, pipe l break events (including condensation from steam releases), and l circulating water system rupture (in either unit). The analyses generally assume that non-water tight doors adjacent to the flood path

[ are leak limiting. Transient flooding calculations are being performed to define bounding water levels and thereby determine which non-water tight doors are actually flood-significant. Pending completion of these calculations, such doors are assumed to be flood-significant for equipment in the room. Hatches and other penetrations over safety related equipment are also assumed to be flood-significant for equipment and panels under the opening, irrespective of the resulting flood level.

Cable submergence is not flood significant, based on original plant j qualification, p 6 / 19 l

l l

L FOR INFORMATION ONLY For postulated circulating water system failures, design basis flooding assumes 20 minutes for operator actions. Alternate barriers for this event are specified for the design basis (20 minute) flood height.

Compensatory measures for this event may be specified for a lower flood height based on posting a flood watch,10 minute operator action, and the effect of the earlier operator action on reducing the resulting flood volume. For all other flooding events from internal hazards, design basis flooding assumes 30 minutes for operator actions. For these other events, the alternate barriers and compensatory measures are specified for the respective design basis (30 minute) flood height.

Flood hazards apply in all plant modes.

D. EQ - STEAM RELEASE High energy line break (HELB) events are described in UFSAR Section 3.6.

A comparison of UFSAR Section 3.6 with Section 3.11 (Environmental Qualification) identified several HELB areas for which the associated harsh environment has not been defined, due to isolation from required equipment by normally closed barriers. Additionally, it was recognized that industry standard environmental analysis techniques (e.g., zone-averaged or homogeneous pressure / temperature calculations) are non-conservative for assessing barrier impairments, due to the possibility of directed jets of high energy fluid through a breach. Further, it would be very difficult to demonstrate acceptable (b)(1) and (b)(2) consequences per 10CFR50.49 for areas not currently designated as steam environments.

To address these concerns, it is necessary to identify and control the barriers between steam releases from HELB events and areas not already defined as harsh for steam. For HELBs in which a specific steam environment is not defined, the applicable barriers were identified by evaluating steam propagation, as follows:

1. Turbine Building and Safety Equipment Building Roof Each Turbine Building and the adjacent Safety Equipment Building roof is subject to a harsh environment from postulated breaks of the main steam and feedwater lines (MSLB, FWLB). Some areas are also subject to a harsh environment from postulated breaks of the auxiliary steam lines (ASLB). Propagation of steam from these HELBs was evaluated qualitatively, considering jet impingement, deflection, plume buoyancy, and tortuous path effects.

, a. 7' Elevation Turbine Building i

Some of the postulated break locations in the main steam and

feedwater lines could result in direct or deflected jets of ,

p 7 / 19 1

FOR INFORMATION ONLY l

high energy fluid to the 7' elevation Turbine Building floor, which could result in deflected flow towards adjacent <

areas. The Saltwater Cooling System (SWCS) piping tunnel hatches are not in the jet impingement paths. However, l steam flow to the hatch covers is assumed. For existing  !

! openings in the hatch covers, credit is taken for condensation on the large piping and concrete surfaces (tortuous path) to prevent steam propagation to the SWCS pump rooms. ,

Steam propagation between Turbine Buildings at the 7' elevation is assumed via deflected flow through the ,

connecting access road (corridor), with upward pluming at i the far end. Upward pluming is credited to prevent MSLB or FWLB interactions from one unit to the other unit's 8' elevation Safety Equipment Building block wall and door openings. Upward pluming is also credited to prevent ASLB interactions with portions of the elevation 8' west wall of the Unit 2 Safety Equipment Building or elevation 9' west r

wall of the Auxiliary Building. Wall locations north of l Turbine Building column K-12 or south of Turbine Building column K-18 (as shown on the hazard barrier drawings) are considered to meet this criterion. (Thore is no corresponding auxiliary steam line in Unit 3.)

b. 30' Elevation Turbine Building Some of the postulated break locations in the main steam lines could result in directed horizontal jets across the west face of the Auxiliary Building at the 30' and 50' l

l elevations. Credit is taken for pluming to prevent MSLB and FWLB steam propagation across the entire width of the l Auxiliary Building at the 30' elevation. However, the entire width of the Auxiliary Building at the 30' elevation is assumed subject to steam from postulated breaks of the auxiliary steam line (ASLB), which runs across this area.

c. 56' and 72' Elevation Turbine Building

, Steam propagation across the west face of the Auxiliary

, Building is assumed to extend across the entire width of the building at the 50' and 70' elevations, due to directed jets and pluming from MSLB, FWLB, and ASLB steam (note: the Turbine Building elevations 56' and 72' adjoin Auxiliary Control elevations 50' and 70').

j l

FOR INFORMATION ONLY l

d. Safety Equipment Building Roof All barriers adjacent to the Safety Equipment Building roof are assumed to be subject to steam from MSLB and FWLB events in this area.

MSLB/FWLB steam hazards from the unit's own systems apply in Modes 1-4 only. MSLB/FWLB hazards from the other unit, and the ASLB hazard, apply in all plant modes.

2. Safety Equipment Building and Penetration Building The Shutdown Cooling Line Break (SDCB), described in NUREG-0712 (NRC Safety Evaluation Report for SONGS 2/3) Section 5.4.3 and SONGS 2/3 Final Safety Analysis Report (FSAR) Q&R 212.132, was evaluated for original plant licensing as a moderate energy line break (MELB, critical crack) in accordance with the 2% exclusion rule specified in NUREG-0800 (Standard Review Plan) Section 3.6.2 Branch Technical Position MEB 3-1. (The line is only at high- 1 energy conditions 2% or less of the time.) In SONGS 2/3, MELBs were required to be considered only as to flooding effects, for I which this event is not limiting. Hence, the SDCB is not included in the current EQ program. However, for barrier control program purposes, it is recognized that this event, initiated at 350 *F 1 and 350 psia, could result in about 13% of the discharged coolant .I flashing to steam. Breaks are postulated in the Penetration Building (9' and 30' elevations) and Safety Equipment Building (safety injection pump rooms). This steam release is not EQ l significant unless it is allowed to propagate to other areas.

l Accordingly, Safety Equipment Building internal barriers and the l barriers from the 9' and 30' Penetration Building to other areas l are applicable to the SDCB steam hazard. l l

l The SDCB steam hazard applies in Mode 4 only.

l

3. Penetration Building and Auxiliary Building (Radwaste) l l Each Penetration Building (PE) and unit-common areas of the i l Auxiliary Building - Radwaste (AR, at elevation 24') are subject to postulated ruptures of the letdown line (LDLB). This event is l being reanalyzed to reduce the EQ consequences (e.g., by crediting control grade isolation to reduce the steam release to less than 2 minutes). Pending completion of the reanalysis, all areas communicating with the break location are assumed to become harsh.

The Unit 2 Penetration Building (corridor from Turbine Building) and unit-common areas of AR (elevations 50' and 63', and routing through elevation 9') are subject to postulated ruptures of the auxiliary steam line. These ruptures are not EQ significant unless allowed to propagate to other areas. Tortuous path effects p 9 / 19 i

l 1

FOR INFORMATION ONLY are credited to prevent potential propagation via the Safety Equipment Building (SE) shutdown cooling piping tunnel. The remaining barriers from these areas to adjacent spaces are applicabl.e.to the LDLB and ASLB steam hazards.

The LDLB steam hazard from the unit's own system applies in Modes 1-4 only. The LDLB hazard from the other unit, and the ASLB hazard, apply in all plant modes.

4. Ventilation System Effects As a result of the steam propagation evaluations discussed above, an evaluation is being performed to assess the significance of barrier penetrations for the normal and emergency ventilation systems as potential steam propagation paths. The results of this evaluation will be incorporated into the barrier tables and associated analyses when complete.

E. EQ - RADIATION  :

Existing plant areas defined as harsh due to post-accident radiation dose are identified in UFSAR Sections 3.11 and 12.3. The post-accident doses result from a combination of airborne dose and direct shine. I Containment airborne leakage is conservatively assumed to be entirely to i the penetration building. Additional airborne terms come from  !

recirculation system and post-accident sampling system leakage to atmosphere. Direct shine comes from piping containing these fluids and from the containment penetrations themselves. Propagation of these doses to any area currently defined as mild would affect both equipment ,

qualification and personnel accessibility within the area, as well as i adjacent to that area.

To address these concerns, it is necessary to control barriers between l harsh radiation areas and areas not already defined as harsh, or to '

evaluate the area and adjacent spaces for (b)(1) and (b)(2) consequences per 10CFR50.49. At this time, the only post-accident mild areas with such an evaluation are within the Safety Equipment Building, which is discussed further below. Compensatory measures may be specified for barriers to airborne dose propagation (which is principally beta), based i on operator action to close the barrier at the ALERT level of accident '

response.

Dose hazards from the unit's own systems apply in Modes 1-4 only. Dose hazards from the other unit apply in all plant modes.

I FOR INFORMATION ONLY

1. Safety Equipment Building EQ - Dose To establish the impact on safety-related electrical equipment in the Safety Equipment Building (SE) and on offsite doses due to the potential increase in radiation levels with barriers impaired, specific evaluations were performed. Normal 40 year doses and the following activity contributions were included in this evaluation:

a. Leakage through Containment Penetrations The UFSAR 15.6.3 accident scenario assumes a post accident source term in the containment and airborne activity leaking to the penetration area. For the SE evaluation, the non-1E exhaust fan from the Penetration Area is assumed to fail and I the radioactive gases accumulate and enter the SE through l open doors and hatches.  :

b. Leakage through Failed Safety Injection Pump Seals l l

The UFSAR 15.6.3 accident scenario assumes a post accident I source term in the containment with failure of the limiting pump seal (LPSI pump) during post-LOCA recirculation. For the SE evaluation, the activity released to the Safety Injection pump room is assumed to propagate to the rest of I the SE through open doors and hatches.

For EQ equipment, the evaluation compared the radiation levels, with the barriers open, to the minimum qualified dose in the EQ Data Packages. It was shown that the qualification levels bound the estimated doses with open doors and hatches.

For non-EQ equipment (i.e., equipment nominally in a mild environment), an evaluation was performed to determine the effect on this equipment of radiation levels due to impaired barriers.

Since this equipment is not on the E0 Master List, this evaluation was performed by comparing the affected equipment with similar equipment that is EQ qualified. The evaluation concluded that safety-related equipment is qualified to the estimated dose levelt with one exception. The exception is the heat tracing power and control panel for the wide-range gas monitor (WRGM: RT7865). To address this exception, the LCS will require the WRGM to be declared inoperable for its accident monitoring function, when the applicable dose barriers are impaired. In addition, non-safety related equipment was also evaluated for potential EQ interactions in accordance with 10CFR50.49(b)(2). Non-safety related equipment interactions were determined to be acceptable.

It is noted that since the nominal configuration of the plant is all barriers closed, the EQ evaluation is not intended to change p 11 / 19

FOR INFORMATION ONLY the design basis of the plant. As such, neither the EQ Master l List, EQ Document Packages, nor calculations which define post-accident environmental conditions will be revised to reflect the plant configuration with impaired barriers. A separate EQ progran, document has been prepared to control the configuration of the non-EQML equipment potentially subject to these conditions.

There is no effect on offsite or control room dose consequences, since the existing design calculations assume all activity released from Containment to the Penetration or Safety Equipment Buildings is released without credit for holdup.

l

2. Ventilation System Effects An evaluation is being performed to assess the significance of barrier penetrations for the normal and emergency ventilation systems as potential dose propagation paths. The results of this l evaluation will be incorporated into the barrier tables and l associated analyses when complete. l F. ALTERNATE BARRIERS l Alternate barriers were limited to those suitable for the respective hazards under design-basis conditions. Seismic Category I concrete l walls and floors were considered suitable as alternate barriers for all hazards if provided with appropriate penetration seals (e.g., radiation- i rated for LOCA dose hazard, flood-rated for flood hazard, etc.) or otherwise shown acceptable by design analysis. Non-load bearing I interior walls (typically, expanded-metal lath and plaster construction) J were considered unsuitable for hazards involving missiles, rupture of non-seismic lines, or dose from LOCA shine.

G. PROTECTED SYSTEMS Preliminary identification of the protected systems in each area was made from the Updated Fire Hazards Analysis (UFHA) area summaries.

Systems associated solely with cables in the area were identified only if missile hazards applied, based on original plant qualification for flood, steam, and dose hazards. To ensure that all affected systems have been identified, this information is being validated against the Plant Equipment Data Management System (PEDMS).

l FOR INFORMATION ONLY H. ALLOWABLEOUTAGETINES(A0Ts)

A0Ts were defined from actual plant need, and the risk of possibly l simaltaneous A0T entries was evaluated for the effect on overall plant rir.,k, using the Units 2 and 3 IPE and Shutdown PRA models, as described i be: low:

1. Basis Based on a review of barrier impairments for maintenance and recurring construction activities under the interim program, a minimum A0T of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is needed to permit repair or l

implementation of compensatory actions for typical barriers, such as water-tight doors. Similarly, a minimum A0T of 7 days is needed to permit major maintenance (e.g., equipment overhauls),

once the compensatory action is in place. These A0Ts are consistent with those specified by the applicable Technical Specifications for safety system active support features (e.g.,

Emergency Chilled Water System, per Technical Specification 3/4.7.10).

The A0T for implementing the initial compensatory actions for the l l critical barriers of a postulated Circulating Water System flood I event was limited by the PRA analysis. (See Section IV.H.5.) A l maximum A0T of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> is needed for acceptable risk consequences for this event. It is expected that a similar limitation on A0T will be needed for the tsunami barriers. (This will be confirmed in the final PRA analysis.) This A0T is consistent with the time needed for the specified initial compensatory actions (e.g., post a flood watch in the Turbine Building). A minimum A0T of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is needed to implement any other compensatory actions for these barriers (e.g., berm openings to elevation 9'0"), consistent with ,

the above.

l

2. Acceptance Criteria

, The annual cumulative risk of Fuel Damage (FD) from design basis l l events attributable to barrier impairments was evaluated using the j following acceptance criterion:

FD < 1.0E-6 This acceptance criterion would be characterized by the PSA Application Guide (EPRI Topical Report TR-105396, "PSA Applications Guide") as "non-risk significant," and is about 3% of l

tho frequency of core damage as calculated in the Units 2 and 3

! IPE (i.e., CDF - 3.0E-5/yr). An acceptance criterion for Significant Release (SR) was not used, since contairiment barriers p 13 / 19 l

I

FOR INFORMATION ONLY will remain subject to the applicable Technical Specifications and

! outside the scope of the proposed LCS.

3. Assumptions

]

1

a. Hazards due to sources inside the plant were

! considered in this stuc'y. Hazards covered in this

! study were flooding, steam release, radiological release, and internal missiles. Flooding hazards due to tsunami are included.

}. b. Fire hazards and external hazards were excluded since 1

the barriers for these hazards are controlled by other programs.

c. Flooding from moderate energy piping system failures was postulated due to critical cracks in the piping system consistent with the licensing basis. The plant flooding analyses were based on this criterion.

} d. The expected number of hours of barrier impairment per year for critical barriers in each building were j

extracted from historical data for the interim control program. Separate values were used for locked / secured

doors and hatches vs. unlocked c'oors. Barrier open l

time associated with normal access and egress through '

i doors was excluded, based on the doors remaining under the immediate control of attendant personnel.

e. Fixed barrier penetration seals were excluded based on impairment history and significance for hazard propagation. Historically, voluntary and as-found impairments of penetration seals have involved degradation vs. complete loss of the hazard barrier ,

function. Since typical penetration seals are I relatively small in area compared to doors or hatches, l significant hazard. propagation could not have occurred .

even in the few cases where impairment involved i complete . loss of the seal. As such, penetration seals will be addressed in a separate evaluation.

f. The models utilized in this study were based on the Units 2 and 3 Individual Plant Examination (IPE) and Shutdown PRA models.

g. Operator action times used in the PRA were consistent with those assumed in the flooding analyses. Operator action probabilities were based on Human Reliability Analysis (HRA). The HRA methodology u?.ilized for this p 14 / 19

f FOR INFORMATION ONLY study was developed and applied in the Accident Sequence Evaluation Program (ASF.P)(NUREG/CR-4772).

l l h. Pipe failure probabilities were based on the EPRI l Report (TR-102266) " Pipe Failure Study Update."

l- 4. Analysis l

A PRA is being performed to determine the average annual cumulative risk of fuel damage due to impaired barriers.

Preliminary results were obtained by a detailed evaluation of the l

hazards applicable to the Safety Equipment Building (SE) barriers.

The SE results were then conservatively scaled to the complete plant, using a scaling factor of 5 (i.e., FD,iont:- 5 x FDst). The final results will be obtained by a detailed evaluation of the complete plant, including the other buildings.

The barrier PRA is based on the Units 2 and 3 IPE and Shutdown PRA models, with newly. developed barrier event trees. Initiating events, such as pipe ruptures, consist of failures which could potentially impact other plant systems if barriers were impaired.

Applicable barrier impairment combinations were considered for propagation of the hazard in each event. Impairment combinations expected to occur from a single, recurring, work activity were treated as a single impairment where appropriate. The consequences of initiating events were identified by deterministic l evaluations such as flooding calculations. Consequences were i evaluated by event and location with impairment of the applicable barriers.

5. Results i

Based on scaling of the SE results to the complete plant, the l acceptance criterion could not be met with a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> A0T to implement compensatory actions, for all barriers. For the l critical barriers which protect against a Circulating Water System )

flood in the Turbine Building, it was necessary to impose a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> l A0T for posting of a flood watch. Analysis of the complete plant is also expected to result in the need for a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> A0T for the l compensatory actions for tsunami barriers. With the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> I (critical) and 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (other) A0Ts to implement applicable compensatory measures, and a 7 day A0T to restore the barriers, the acceptance criterion is met.

l FOR INFORNATION ONLY V. ADNINISTRATIVE CONTROLS A. EXISTING PROGRANS l

There are several existing programs which control many of the hazards barriers in the plant. These are identified below:

Barrier Type Existing Control Program Fire Barriers Technical Specifications and FPE i Impairment Process Security Barriers Security Procedures and Work

Authorization Request (WAR) Process Control Room and FH Technical Specifications and l HVAC Boundaries Procedures Other HVAC Equipment Control and WAR Evaluation Boundaries Process HELB Pipe Whip and WAR Evaluation Process Jet Impingement Barriers Tornado Missile Severe Weather Abnormal Operating Instruction

, External Flood Severe Weather Abnormal Operating i

Barriers (Probable Instruction Maximum Flood)

Containment Technical Specifications and Procedures B. NEW ADNINISTRATIVE CONTROLS A new program will be implemented for control of barriers which protect the plant against internal sources of missiles, flooding, and harsh environment hazards, such as steam and radiation. This program will consist of administrative controls implemented through a Licensee l Controlled Specification (LCS).

1. Licensee Controlled Specification The proposed LCS for each Unit addresses unit-specific and common barriers. Each LCS includes three tables, two for barriers with ,

EQ or internal missile functions, and one for barriers which do I not have either of these functions. Some of the barriers l controlled through the LCS are also subject to existing Technical Specification controls for fire barriers, the fuel handling isolation (FHIS) boundary, or control room isolation boundary (CREACUS). The overlap with fire barrier Technical Specifications p 16 / 19

I FOR INFORMATION ONLY is identified generically in the LCS. The overlap with FHIS and CREACUS Technical Specifications is identified specifically in the LCS tables. Impairment of any barriers not identified in these tables will be controlled via the 10CFR50.59 process. Barriers and applicable requirements may be added, modified or deleted from the LCS tables via a 10CFR50.59 evaluation and the applicable procedures for revising Licensee Controlled Specifications.

Critical barriers identified by the PRA evaluation (e.g., for the Circulating Water Flood in the Turbine Building) are identified in Table 1. Other barriers with EQ or internal missile functions are identified in Table 2 of the LCS. In Table 1 and Table 2, each barrier is identified by the area being protected, the systems being protected, the hazard source area, the applicable hazards, and the alternate barriers and/or compensatory measures available for each of the hazards. The LCS requirements for Table 1 and Table 2 barriers are applicable whenever a protected system is required to be operable and the applicable hazards can occur. The hazards, protected systems (and associated Tech Specs), alternate barriers, and compensatory measures are identified by Unit Mode (Mode 1-4, or Mode 5/6/Defueled), where applicable.

2. Allowable Outage Times (A0Ts)

The LCS permits Table 1 barriers to bo impaired for only 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.  ;

The LCS permits any Table 2 barrier to be impaired for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Prior to the end of these respective A0Ts, the alternate ,

barrier or compensatory. measures identified in the respective l Table must be implemented, or the impaired barrier restored, or l further impairment justified by a 10CFR50.59 evaluation, or the protected equipment declared inoperable and its applicable ,

Technical Specification Action (s) implemented. Implementing the i alternate barriers for all specified hazards permits exit from the l LCS action. Implementing the compensatory measures (or a combination of alternate barriers and compensatory measures) for )

i all specified hazards permits the barrier to remain non-functional l for up to 7 days. Prior to the end of the 7 day A0T, the impaired barrier must be restored, or the alternate barrier implemented, or further impairment justified by a 10CFR50.59 evaluation, or the protected equipment declared inoperable and its applicable Technical Specification Action (s) implemented. Technical Specification 3.0.3 is the applicable Tech Spec Action for some areas (e.g., those which have not been evaluated for 10CFR50.49(b)(2) interaction effects). However, based on the experience with the interim program, it is expected that 10CFR50.59 evaluations would continue to be performed to preclude the need for plant shutdown due to barrier impairments for one of these areas, p 17 / 19

FOR INFORMATION ONLY

3. Surveillances Periodic surveillances are included for Table 1 and Table 2 barriers. These surveillances will be performed by FPE and Maintenance. Table 3 barriers have no EQ or missile functions, and hence no required surveillances under this LCS unless used as an alternate barrier per Table 1 or Table 2.

SR 3.7-lxx.1 and SR 3.7-lxx.2 require periodic verification that movable hazards barriers (door, water-tight door, hatch, manhole cover, or block wall) are FUNCTIONAL. Movable barriers are FUNCTIONAL when they are closed and capable of remaining in that configuration during the applicable EQ/ missile events. For example: a door with a broken lock is still FUNCTIONAL if it will remain latched; a door with a broken latch is still FUNCTIONAL if it will not open due to differential pressure from ventilation, flooding, or HELB dynamic effects, and is not a barrier for HELBs of non-seismic lines. Movable barriers which are not locked or otherwise secured are required to be surveilled daily. Movable barriers which are locked or otherwise secured (e.g., hatches which cannot be moved without lifting gear) are required to be surveilled once per month. These surveillances will be performed coincident with the fire barrier surveillances per Technical Specification 3/4.7.9.

SR 3.7-lxx.3 and SR 3.7-lxx.4 require periodic verification of gasket contact and the performance of related preventive maintenance items (PMs) for water-tight doors. A sliding surveillance frequency is specified, consistent with the wide variation in service severity of water-tight doors (e.g., from low l to high traffic, and ventilation-seated vs. -unseated l applications). An initial surveillance frequency of 12 months is specified for unlocked doors. For unlocked doors which pass the gasket contact criterion as-found at two successive surveillances, the surveillance frequency can be reduced to the next lower value.

For unlocked doors which do not pass the gasket contact criterion as-found at two successive surveillances, the surveillance frequency is increased to the next higher value. The minimum and maximum surveillance frequencies are 24 months and 30 days, respectively. For locked doors, which are inherently low-traffic ,

and wear, a surveillance frequency of 24 months is specified.  !

SR 3.7-1xx.5 and 6 require periodic verification that fixed hazards barriers (wall, floor, roof, or penetration seal) are FUNCTIONAL. Fixed barriers are FUNCTIONAL when they are closed or capable of closing and remaining in that configuration during the applicable EQ/ missile events. For example, a penetration seal that is capped on only one side is still FUNCTIONAL. Wall s, floors, and roofs are required to be surveilled once per 24 p 18 / 19

FOR INFORMATION ONLY l months. Penetration seals, including conduit seals, are required to be surveilled on a 24 month sampling basis, consistent with fire barrier Technical Specification requirements. Fire dampers may also be included in these surveillances, if required by the results of the ventilation system effects evaluations discussed in sections IV.D.4 and IV.E.2 above. These surveillances will be performed coincident with the fire barrier surveillances per Technical Specification 3/4.7.9.

4. Implementation A detailed implementation plan for the hazards barrier LCS is being developed. In addition to procedure changes and training, the plan will include appropriate changes in signage and simplified tracking for impairments which can be completed within the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> or 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> A0Ts. This will permit a significant reduction in pre-planning time and engineering support required for activities such as corrective maintenance. The plan will also include a follow-up evaluation of the risk impact associated with barrier impairments, and appropriate program changes if needed.

Implementation of the LCS will not occur until completion of the supporting design documentation and final engineering review of the LCS tables. This documentation includes formal revision of the EQ zone drawings, calculation supplements and revisions, and new EQ program documents. These supporting activities are presently scheduled to occur by September 1, 1996.

If the area is a buffer space for adjoining areas containing protected equipment (as defined under PROTECTED EQUIPMENT AREA above), the designation for the area containing the protected equipment is listed in this field instead (eg. (2 - AR-09 -07 6) ) .

In Modes 1-4, if the PROTECTED SYSTEMS must be declared inoperable and: a) the affected areas have not been evaluated for 10 CFR 50.49 (b) (2) effects, or b) if both trains of required systems must be declared inoperable and this is not specifically addressed under the system Technical Specification, then Tech Spec 3.0.3 applies. In Modes 5/6/Defueled, one or more of Technical Specifications 3/4.1.2 (CVCS), 3/4.3.1 (RPS), 3/4.3.2 (ESFAS), 3/4.4.1.4 or 3/4.9.8 (SDCS), 3/4.7.5 (CREACUS), 3/4.7.10 (ECWS), 3/4.8.3 (electrical distribution) or 3/4.9.12 (PACU) would apply. Fire Protection requirements per Technical Specification 3/4.7.9 also apply to most barriers, but are controlled through a separate program.

HAZARD SOURCE AREA:

The plant area number (unit, building, elevation and area) in which the APPLICABLE HAZARDS may exist without credit for alternate barriers. These hazards (eg. line break events) may occur in the specified source area, or propagate through the specified source area from another location (eg. through a corridor from the turbine building). The same abbreviations are used as defined for hazard source areas, above.

APPLICABLE p m ns:

The Environmental Qualification (EQ) and internally-generated missile hazards that apply to the specified source area, including steam, radiation and flooding. The hazards are applicable in UNIT 2 + COMMON FOR INFORMATION ONLY p 2 / 14

LCS 3.7-1 m TABLE 1 CRITICAL nonIERS WITH EQ/ MISSILE FUNCTIONS all Modes unless otherwise specified (eg. Mode 1-4, or Mode 5/6/Defuel). If no hazards apply in the Mode, this is shown as (none). The following hazard abbreviations are used in conjunction with the building abbreviations defined above to define the source location:

ASLB: Auxiliary Steam Line Break (for example, ASLB (50'AR)). Postulated ruptures of the non-seismic auxiliary steam line result in direct release of high temperature steam (366 F) and flooding due to steam condensation. ASLBs in the AR building are assumed to drain to the 9' PB and Shutdown Cooling System piping tunnels. This hazard applies in all Modes.

CNS flood: Circulating Water System flood. Postulated ruptures of the non-seismic circulating water system in either unit results in flooding of both turbine buildings to elevation +10'6".

This hazard applies in all Modes.

FNLB: FeedWater Line Break. Postulated ruptures of the non-seismic main feedwater system results in direct release of high temperature steam (due to flashing) and flooding with jet impingement effects. This hazard applies in Modes 1-4. Some common areas are affected by a FNLB in both Units.

Internal flooding: Flooding due to fire suppression system operation or postulated ruptures of piping (including condensation from steam line breaks) or tank walls. " Internal" distinguishes these events from flooding due to external sources (eg. probable maximum precipitation events),

which are addressed by the Severe Weather AOI. This hazard applies in all Modes.

Internal missiles: Postulated missiles from rotating equipment and high energy lines.

" Internal" distinguishes these events from missiles due to external sources (eg. tornado missiles), which are addressed by the Severe Weather AOI. This hazard applies in all Modes.

I LDLB: Letdown Line Break. Postulated rupture of the Letdown system piping will result in direct release of high temperature steam (due to flashing) and flooding. Portions of the Letdown system piping in area AR are non-seismic. This hazard applies in Modes 1-4. Some common areas are affected by a LDLB in both Units.

LOCA: Loss of Coolant Accident. Postulated rupture of the Reactor Coolant System in containment with 'IMI source terms is assumed to result in a gradual release of airborne activity to the Penetration Building and Safety Equipment Building (LOCA airb), and in gamma UNIT 2 + COMMON FOR INFORMATION ONLY p 3 / 14

Doors (other than R-suffix designated shield doors) do not perform a barrier function for LOCA shine. This hazard applies in Modes 1-4. Some common areas are affected by a LOCA in both Units.

MSLB: Main Steam Line Break. Postulated rupture of the main steam lines results in direct release of high temperature steam with jet impingement effects, and flooding due to condensation. Main steam piping in area TB, and portions of the main steam lines in area SE '

are non-seismic. This hazard applies in Modes 1-4. Some common areas are affected by a MSLB in both Units. ,

SDCB: Shutdown Cooling Break. The shutdown cooling system is a high energy system only during l Mode 4 operation. Postulated critical cracks in the shutdown cooling piping under these conditions will result in direct steam release (due to flashing) and flooding.

Tsunami flooding: Flooding due to a postulated seismic displacement of the sea floor at the Hypothesized Offshore Zone of Deformation. Tsunami run-up is additive to other concurrent sea conditions (including tide, storm surge and wave action). This hazard applies in all Modes.

I ALTERNATE BARRIERS:

Barriers or actions which provide equivalent protection against the specified hazards. For example, closing the Control Room missile doors provide protection against MSLB steam equivalent to that provided by the normal barrier doors. Non-load bearing interior walls can not be credited as ALTERNATE BARRIERS for postulated ruptures of non-seismic lines (eg.

MSLB/FWLB outside containment) or for LOCA dose hazards, due to seismic failure modes and inadequate sectional density for shielding. If no ALTERNATE BARRIERS are defined, this is shown as (NONE AVAILABLE). If the hazards do not apply in certain Modes (eg. Modes 5/6/Defueled), this is shown as (none required).

COMPENSATORY MEASURES:

Actions which temporarily eliminate the hazard or reduce its consequences to an acceptable level. For example: a) Securing a system needed for unrestricted power operation (eg. 1 auxiliary steam) can temporarily eliminate a hazard; b) Posting a flood watch can reduce a hazard by changing the assumed duration of the flood source from 20 minutes (design basis) to

, 10 minutes. If no COMPENSATORY MEASURES are defined, this is shown as (NONE AVAILABLE). If UNIT 2 + COMMON FOR INFORMATION ONLY p4 / 14

This area may contain the PROTECTED SYSTEMS or (if the other walls / floors of the area are not sealed against the hazard) serve as a buffer space against propagation of the hazards into the areas in which the PROTECTED SYSTEMS are actually located.

The specified barriers include WALLS, FLOORS, PENETRATION SEALS, DOORS, WATER-TIGHT (WT) DOORS, and HATCHES as applicable. (Conduit seals are considered PENETRATION SEALS in this table.) .

The following abbreviations are used for buildings:

AC: Auxiliary Building (Control Area). This building / area is common to both Unit 2 and 3.

AR: Auxiliary Building (Radwaste Area). This building / area is common to both Unit 2 and 3.

CT: Cable Tunnel. Each unit has its own Cable Tunnel'.

DG: Diesel Generator Building. Each unit has its own Diesel Generator Building.

FH: Fuel Handling Building. Each unit has its own Fuel Handling Building.

PE: Penetration Building. Each unit has its own Penetration Building.

SE: Safety Equipment Building. Each unit has its own Safety Equipment Building.

TB Turbine Building. Each unit has its own Turbine Building. Portions of the Turbine Buildings are common to both Units, including the intake structure area and Saltwater Cooling System piping tunnels.

LCS 3.7-13ac TABLE 2 OTHER BARRIERS WITH EQ/ MISSILE FUNCTIONS TK: Tank Building. Each unit has its own Tank Building.

YD: Yard Area. Yard Areas 2-YD-30-200A and 2-YD-30-200B ace the Unit 2 + common and the Unit 3 yard areas, respectively. These area designations arc. used for the roof areas of buildings for which a separate area designation is not assigned.

PROTECTED SYSTEMS (Acolicable T/S):

The safety related and safe shutdown system trains located in the PROTECTED EQUIPMENT AREA, and the Technical Specifications which apply if they must be declared inoperable. The specific systems are identified in the applicable UFHA sections for each area. Cable is not included (based on original plant qualification) unless missile hazards apply to the area. Due to the large number of systems / trains in some areas, this may be shown as various (Train A/B) or similar. If the area is a buffer space for adjoining areas containing protected equipment (see discussion under PROTECTED EQUIPMENT AREA above), the designation for the area containing the protected equipment is listed in this field instead (eg. (2-AR-03-076)).

In Modes 1-4, if the PROTECTED SYSTEMS must be declared inoperable and: a) the affected areas have not been evaluated fc r 10 CFR 50.49 (b) (2) effects, or b) if both trains of required systems must be declared inoperable and this le-not specifically addressed under the system Technical Specification, then Tech Spec 3.0.3 applies. In Modes 5/6/Defueled, one or more of Technical Specifications 3/4.1.2 (CVCS), 3/4.3.1 (RPS), 3/4.3.2 (ESFAS), 3/4.4.1.4 or 3/4.9.8 (SDCS), 3/4.7.5 (CREACUS), 3/4.7.10 (ECWS), 3/4.8.3 (electrical distribution) or 3/4.9.12 (PACU) would apply. Fire Protection requirements per Technical Specification 3/4.7.9 also apply to most barriers, but are controlled through a separate program.

HAZARD SOURCE AREA:

The plant area number (unit, building, elevation and area) in which the APPLICABLE HAZARDS may exist without credit for alternate barriers. These hazards (eg. line break events) may occur in the specified source area, or propagate through the specified source area from another location (eg. through a corridor from the turbine building). The same abbreviations are used as defined for hazard source areas, above.

APPLICABLE HAZARD _R:

The Environmental Qualification (EQ) and internally-generated missile hazards that apply to the specified source area, including steam, radiation and flooding. The hazards are applicable in UNIT 2 + COMMON FOR INFORMATION ONLY p 2 / 128

LCS 3.7-1xx TABLE 2 OTHER BARRIERS WITH EQ/ MISSILE FUNCTIONS all Modes unless otherwise specified (eg. Mode 1-4, or Mode 5/6/Defuel). If no hazards apply in the Mode, this is shown as (none). The following hazard abbreviations are used in conjunction with the building abbreviations defined above to define the source location:

ASLB: Auxiliary Steam Line Break (for example, ASLB (5 0 ' AR) ) . Postulated ruptures of the non-seismic auxiliary steam line result in direct release of high temperatura steam (366 F) and flooding due to steam condensation. ASLBs in the AR building are assumed to drain to the 9' PB and Shutden Cooling System piping tunnels. This hazard applies in all Modea.

CNS flood: Circulating Water System flood. Postulated ruptures of the non-seisnic circulating water system in either unit results in flooding of both turbine buildings to elevation +10'6".

This hazard applies in all Modes.

FMLB: FeedWater Line Break. Postulated ruptures of the non-seismic main feedwater system results in direct release of high temperature steam (due to flashing) and flooding with jet impingement effects. This hazard applies in Modes 1-4. Some common areas are affected by a FMLB in both Units.

Internal flooding: Flooding due to fire suppression system operation or postulated ruptures of piping (including condensation from steam line breaks) or tank walls. " Internal" distinguishes these events from flooding due to external sources (eg. probable maximum precipitation events),

which are addressed by the Severe Weather AOI. This hazard applies in all Modes.

Internal missiles: Postulated missiles from rotating equipment and high energy lines.

" Internal" distinguishes these events from missiles due to external sources (eg. tornado missiles), which are Oddressed by the Severe Weather AOI. This hazard applies in all Modes.

LDLB: Letdown Line Break. Postulated rupture of the Letdown system piping will result in direct release of high temperature steam (due to flashing) and flooding. Portions of the Letdown system piping in area AR are non-seisnic. This hazard applies in Modes 1-4. Some common areas are affected by a LDLB in both Units.

LOCA: Loss of Coolant Accident. Pectulated rupture of the Reactor Coolant System in containment with TMI ciource terms is assumed to result in a gradual release of airborne activity to the Penetration Building and Safety Equipment Building (LOCA airb), and in gamma UNIT 2 + COMMON FOR INFORMATION ONLY p 3 / 128

LCS 3.7-1xx TABLE 2 OTHER BARRIERS WITH EQ/ MISSILE FUNCTIONS dose via shine from containment piping penetrations and post-accident recirculation piping (LOCA shine). Doors (other than R-suffix designated shield doors) do not perform a barrier function for LOCA shine. This hazard applies in Modes 1-4. Some common areas are affected by a LOCA in both Units.

MSLB: Main Steam Line Break. Postulated rupture of the main steam lines results in direct release of high temperature steam with jet impingement effects, and flooding due to condensation. Main steam piping in area TB, and portions of the main steam lines in area SE are non-seismic. This hazard applies in Modes 1-4. Some common areas are affected by a MSLB in both Units.

SDCB: Shutdown Cooling Break. The shutdown cooling system is a high energy system only during Mode 4 operation. Postulated critical cracks in the shutdown cooling piping under these conditions will result in direct steam release (due to flashing) ano flcoding.

Tsunami flooding: Flooding due to a postulated seismic displacement of the sea floor at the Hypothesized Offshore Zone of Deformation. Tsunami run-up is additive to other concurrent sea conditions (including tide, storm surge and wave action). This hazard applies in all Modes.

ALTERNATE BARRIERS:

Barriers or actions which provide equivalent protection against the specified hazards. For example, closing the Control Room missile doors provide. protection against MSLB steam equivalent to that provided by the normal barrier doors. Non-load bearing interior walls can not be credited as ALTERNATE BARRIERS for postulated ruptures of non-seismic lines (eg.

MSLB/FWLB outside containment) or for LOCA dose hazards, due to seismic failure modes and inadequate sectional density for shielding. If no ALTERNATE BARRIERS are defined, this is shown as (NONE AVAILABLE). If the hazards do not apply in certain Modes (eg. Modes 5/6/Defueled), this is shown as (none required).

COMPENSATORY MEASURES:

Actions which temporarily eliminate the hazard or reduce its consequences to an acceptable level. For example: a) Securing a system needed for unrestricted power operation (eg.

auxiliary steam) can temporarily eliminate a hazard; b) Posting a flood watch can reduce a hazard by changing the assumed duration of the flood source from 20 minutes (design basis) to 10 minutes. If no COMPENSATORY MEASURES are defined, this is shown as (NONE AVAILABLE). If UNIT 2 + COMMON FOR INFORMATION ONLY p 4 / 128

Table 2 consists of 4 sections (for Protected Equipment Areas AC, AR, CT through PE, and SE through YD). Each section is sorted by PROTECTED EQUIPMENT AREA (unit, building, level, area number, room number) . Within each PROTECTED EQUIPMENT AREA, entries are further sorted by HAZARD SOURCE AREA (unit, building, level, area number, room number). Leading zeroes are included in the level and area numbers (eg. 2-AC-09-005 vs. 2-AC-9-5) for correct sorting.

Related barriers which are not listed (eg. wall adjacent to a specified door, penetration seal adjacent to a specified seal, etc.) may nnt be added to this listing without a specific evaluation per 10CFR50.59.

AED 1. AREA 2: The plant area numbers (unit, building, elevation and area) and rooms between which the specified barrier is located. Areas 2-YD-30-200A and 2-YD-30-200B are the Unit 2 l and Unit 3 yard areas, respectively, which include the roof areas of other buildings for which a separate fire area designation is not assigned.

REMARKS: Other pertinent or clarifying information.

l 1. Unless noted otherwise, all barriers in this table are subject to applicable controls outside this LCS for one or more of the following functions: fire protection; severe weather AOI; Fuel Handling Isolation System boundary; CREACUS boundary; security. Where none of these functions apply, "No comp measures req'd" is shown in the Remarks.

2. Barriers which can provide EQ/ missile functions as an alternate to a Table 2 barrier are shown as " Table 2 alternate barrier" in the Remarks. Table 3 barriers with t

this designation are subject to the same surveillance
