Enclosure 13.18 PT/1/A/11o3/o15 Shutdown Margin Calculation at Power Page 1 of 1

1. Purpose 1.1 The purpose of this enclosure is to perform a shutdown margin calculation while at power.

2. Procedure Performed By:

NOTE: Step 2.1 applies only to control rod groups 1 through 6. Group 7 and the APSRs may be positioned as required.

2.1 IF any groups are NOT at 100% withdrawn (other than Group 7 and the APSRs) due to CRD movement PT:

2.1.1 Verify that only one group is NOT at 100% withdrawn.

2.1.2 Verify that the inserted group is? 95% withdrawn.

NOTE: For a dropped rod/stuck rod scenario, utilize 1 inoperable rod graphs in the COLR. The rod position used should be the position of the controlling group (if the dropped/stuck rod is in the controlling group, the rod positions of remaining rods in that group should be used, not the group average.)

2.2 Verify of the following:

2.2.1 Available shutdown margin is 1% AK/K. This is shown by verifying that the 5V control rod position and power level are within the Acceptable Region or the Restricted Region on the appropriate curve for the number of RC Pumps and Inoperable rods in the COLR.

OR 2.2.2 Appropriate actions are taken per TS 3.1.4, 3.1.5, and 3.2.1 sv

16.13.1-2 05/13/04

Minimum Station Staffing Requirements 16.13.1 BASES Some of the requirement(s) of this SLC section were relocated from TS 6.1.1.9 and TS Table 6.1-1 during the conversion to ITS. These requirements were initially relocated to SLC 16.13.5, Additiona Operating Shift Requirements, dated 3/27/97.

The requirements of this SLC consolidate ONS station staffing requirements into one document. This SLC includes the shift manning requirements of ITS 5.2.2, 10 CFR 50 Appendix R Section IILH, 10 CFR 50.54.m, Operations Management Procedures (OMP s), NSD 112, and the Emergency Plan. This SLC also includes the old requirements of SLC 16.13.1

,

Fire Brigade, dated 3/27/99 and SLC 16.13.5; Additional Operating Shift Requirements dated 3/27/99. The numbers for each position per shift are additive. For example, Table 16.13.1

-1 requires a total of 5 SROs per shift (3 SROs required by 10 CFR 50.54(m)(2)(i) plus 1

additional SRO for the Fire Brigade and 1 additional for the ERO). The bases for the numbers in the first column of SLC Table 16.13.1-1 are as follows:

1 OSM (active SRO) Required by 50.54(m)(2)(ii) (implemented by OMP).

1 STA (active or inactive SRO) Required by ITS 5.2.2.g which indicates the individual fulfilling the STA position is the Shift Work Manager (implemented by OMP). Revision 50 to OMP 2-1 renamed the person fulfilling this position an STA. Note that pre-conversion TS Table 6.1-1, which implemented NUREG-0737 requirements, did not require an STA on shift when no units were in MODES 1-4. The SLC Table is more restrictive in that it requires an STA on shift at all times.

3 SROs (active SRO) Required by 10 CFR 50.54(m)(2)(i). Per ITS 5.2.2.b and 10 CFR 50.54(m)(2)(iii) at least 2 SROs must be in the control room.

1 SRO (active or inactive) or NLO Required by Appendix R Section IIl.H.

- Fire Brigade Implemented by OMP and NSD. Individual fulfilling position shall be a SRO or an NLO who is qualified to be a fire brigade leader. Per OMP this individual functions as fire brigade leader and is not available for control room activities when directing the fire brigade. Appendix R does not specify that the brigade leader be an SRO, it only specifies that the fire brigade leader have sufficient training in or knowledge of plant safety-related systems to understand the effects of fire and fire suppression systems on safe shutdown capability. When an 16.13.1-3 05/13/04

Minimum Station Staffing Requirements 16.13.1 NLO is serving as the fire brigade leader, the SRO number for each column in Table 16.13.1-1 may be reduced by one.

1 SRO (licensed or previously Required by Volume A, Section B, Figure B-2 of licensed) ERO

-

the Emergency Plan. Implemented by OMP. SRO serves as the offsite communicator and the NRC communicator in the CR/TSC. This is permissible since the offsite communicator role is completed prior to the NRC communicator role starting.

5 ROs Required by 10 CFR 50.54(m)(2)(i).

1 RO - SSF Required by ITS 5.2.2.h, implemented by OMP.

Per ITS 5.2.2.h, the manpower necessary to operate the SSF will be exclusive of the fire brigade and the minimum operating shift that is required to be present in the Control Room. ITS 5.2.2.b andlO CFR 50.54(m)(2)(iii) require 3 of the 5 ROs required by 10 CFR 50.54(m)(2)(i) to be present in the control room when fuel is in the reactor. When all three units are in MODES 1-3, one RO per unit must be available to be dispatched to the SSF.

Since 3 ROs must be present in the Control Room only two are available to dispatch to the SSF.

Therefore, one additional RO, beyond what is required by 10 CFR 50.54(m)(2)(i), is required.

1 RO ADV

-

Amendment 314, 314, 314 requires that staffing level be increased by an additional RO beyond what is required in Table 16.13.1-1 when in Condition B of ITS 3.5.2. The additional RO is designated to respond to an event requiring activation of the SSF for the unit operating under ITS 3.5.2 Condition B. The additional RO role may be fulfilled by an SRO as long as the SRO is not being counted towards the number of required SROs listed in Table 16.13.1-1 and is qualified to tasks involving operation of the SSF systems.

When all three units are in MODES 1-4, a total of seven ROs are required; five per 10 CFR 50.54(m)(2)(l), one per ITS 5.2.2.h, and one per ITS 3.5.2 Condition B.

8 NLOs Required by 10 CFR 50 Appendix R Part lll.H, ITS 5.2.2.a, Volume A, Appendix 8, Spill Prevention 16.13.1-4 05/13/04

Minimum Station Staffing Requirements 16.13.1 and Control and Counter Measures Plan, Revision 98-04, 10/98 of the Emergency Plan, and Volume A, Section B, Figure B-8 of the Emergency Plan.

Implemented by OMP. (Four for fire brigade, one NLO per Unit to complete critical AP and EOP actions and 1 for SSF equipment verification for the design basis Appendix R fire.) When an NLO is serving as the fire brigade leader, the NLO number for each column in Table 16.13.1-1 must be increased by one or one fire brigade member must be supplied from another organization.

The number of NLOs that are fire brigade qualified may be reduced provided that a like number of fire brigade qualified personnel are provided from other organizations. This does not change the total number of NLOs required; only the number required to be fire brigade qualified.

2 NLOs ADV License Amendment 314, 314, 314 requires that staffing levels be increased by an additional two NLOs beyond those required in Table 16.13.1-1 when in Condition B of ITS 3.5.2. The additional NLOs are designated for the purpose of operating the Atmospheric Dump Valves (ADVs) for the unit under ITS 3.5.2 Condition B. In addition, the NLOs with the responsibility for operating the ADVs will be designated to respond to the control room within five minutes and will not be given duties that will prevent this from happening.

7 SPOC Required by Volume A, Section B, Figure B-8 of the Emergency Plan and the Fire Plan (Volume A, Appendix 8, Spill Prevention and Control and Counter Measures Plan, Revision 98-04, 10/98).

Implemented by OMP 1-7 and NSD 112. Consists of two I&E technicians ERO qualified and knowledgeable of IP/0/A0050/003 (Power SSF Submersible Pump), two MM technicians ERO qualified and knowledgeable of MP/0/AI1 300/059 (Install SSF Submersible Pump), one supervisor or temporary supervisor qualified to establish the OSC and perform the OSC Maintenance Supervisor functions, and one additional person to help with pump installation as directed by SPOC supplied by one of the following groups in the order 16.13.1-5 05/13/04

Minimum Station Staffing Requirements 16.13.1 listed: SPOC, other maintenance personnel onsite, C&F, Chemistry, RP and Maintenance Overtime resources. Security will automatically supply one Security Guard to open doors and gates who will also assist with any maintenance activities to be performed. The Security Guard is counted as one of a total of 6 people needed to install the submersible pump. One other person is needed to establish the OSC for a total of 7. In the event of a fire, SPOC will respond to the fire until directed to install the submersible pump. A total of 5 SPOC personnel are assigned to the fire brigade. Per PIP 4-099-2987 problem evaluation, it is acceptable to consider these additional 5 Fire Brigade members to be available for other duties, such as installation of the SSF pump. This is based on Oconee Fire Brigade Guide #2, which contains guidance that allows fire brigade members to be released from the brigade for operational needs at the discretion of the OSCITSC.

The number of SPOC personnel qualified as fire brigade members may be reduced, provided that the qualified fire brigade members from other organizations are increased by a like number. This does not change the total number of SPOC personnel required, only the number required to be fire brigade qualified.

1 Chemistry Technician ERO

-

Required by Volume A, Section B, Figure B-8 of the Emergency Plan. Implemented by OMP and Station Chemistry Manual 2.6. A Chemistry Technician who is fire brigade qualified may be credited toward fulfilling the ERO requirement and the fire brigade requirement. In the event of a fire, the Chemistry technician will respond to the fire until directed otherwise.

3 RP Technicians Three are required by Volume A, Section B, Figure B-8 of the Emergency Plan. One is required by ITS 5.2.2.d and may be counted towards fulfilling the ERO requirement. Implemented by HPIOIBI1000IO54. RP technicians who are fire brigade qualified may be credited toward fulfilling the ERO and TS requirements and the fire brigade requirement. In the event of a fire, the RP 16.13.1-6 05/13/04

Minimum Station Staffing Requirements 16.13.1 technician will respond to the fire until directed otherwise.

Minimum Station Staffing numbers for the SRO and RO positions in Table 16.13.1

-1 change as a function of the number of units in MODES 1-4 and whether the operating Units are controlled from one or two Control Rooms. The number for the remaining positions in Table 16.13.1-1 is not affected by operational condition of the units.

10 CFR 50.54(m)(2)(i) requires 3 SROs when two units are in MODES 1-4 and contro lled from two Control Rooms, 2 SROs when two units are in MODES 1-4 and controlled from a common control room, 2 SROs when one unit is MODES 1-4 and 1 SRO when no units are MODES 1-4. Thus considering fire brigade and ERO requirements, this results in the requirement for 5 SROs when two units are in MODES 1-4 and controlled from two Control Rooms, 4 SROs when two units are in MODES 1-4 and controlled from a commo n control room, 4 SROs when one unit is MODES 1-4 and 3 SROs when no units are MODES 1-4.

10 CFR 50.54(m)(2)(i) requires 5 ROs when two units are in MODES 1-4 and controlled from two Control Rooms, 4 ROs when two units are in MODES 1-4 and contro lled from a common control room, 4 ROs when one unit is MODES 1-4 and 3 ROs when no units are MODES 1-4. OMPs require 2 ROs to man the SSF when two units are in MODES 1-3 and 1 RO when one unit is MODES 1-3. None are required when no units are in MODES 1-3.

Therefore, no additional ROs are required beyond what is required by 10 CFR 50.54(m)(2)(i) when less than three units are in MODES 1-3 with one exception.

When two units are in MODES 1-3 and controlled from one Control Room one additio nal RO is required since 10 CFR 50.54(m)(2)(i) only requires 4 ROs when the two operating units (Units 1 and 2) are controlled from one control room. Since one RO (or SRO) must be present in the Control Room when fuel is in the reactor vessel, the two ROs required to man the SSF for the operating units are exclusive of the one RO require d for each unit.

Therefore, a total of 5 ROs are required for this configuration.

The minimum staffing number for the SPOC and NLO positions is reduce d by one when all three units are in MODE 4 or below. This reduction is allowed since the SSF is not required to be OPERABLE in these MODES. Therefore, there is no need for SPOC to provide a qualified individual to establish the OSC and no need for an NLO to perform SSF equipment verification.

SLC 16.13.1.a.1 requires at least one ROper unit to be present in the contro l room when fuel is in the reactor and one SRO to be present in the control room while in MODES 1-4. This requirement is based on 10 CFR 50.54(m)(2)(iii) and ITS 5.2.2.b. The first part of SLC 16.13.1 .a.2, which requires at least one licensed operator to be in the reactor building when fuel handling operations in the reactor building were in progress, was relocat ed during the ITS conversion from TS Table 6.1-1, Additional Requirement 3. This require ment has existed since the initial issuance of Oconee Technical Specifications. The second part of SLC 16.13.a.2, which requires that a SRO or an SRO limited to fuel handling activities be present to directly supervise CORE ALTERATIONS including fuel loading or transfer and be assigned no other duties, is based on 10 CFR 50.54(m)(2)(iv). SLC 16.13.1.a.3 which requires an operator, in 16.13.1-7 05/13/04

Minimum Station Staffing Requirements 16.13.1 addition to those specified in ITS 5.2.2.b to supplement the control room staff if the computer for a reactor is inoperable for more than eight hours, was relocated during the ITS conversion from TS Table 6.1-1, Additional Requirement 6. This requirement has also existed since the initial issuance of Oconee Technical Specifications. SLC 16.13.1.b, which specifies the STA shall be an experienced SRO was relocated during the ITS conversion from TS 6.1.1.9.

The primary purpose of the Fire Protection Program is to minimize both the probability and consequences of postulated fires. Despite designed active and passive Fire Protection Systems installed throughout the plant, a properly trained and equipped Fire Brigade organization of at least ten (Reference 8) members is needed to provide immediate response to fires that may occur at the site. This number is the result of a corrective action from Reference

10. This Fire Brigade requirement is normally met by using one SRO (or NLO qualified to be a

fire brigade leader), 4 NLOs, and 5 SPOC personnel. However, this requirement can also be met by using personnel from other organizations (e.g., Chemistry, Radiation Protection, and Security).

Fire Brigade equipment and training conform to Oconees commitments to Appendix A to Branch Technical Position 9.5-I and supplemental NRC Staff guidelines including Nuclea r Plant Functional Responsibilities, Administrative Controls and Quality Assurance.

This SLC is part of the Oconee Fire Protection Program and therefore subject to the provis ions of Oconee Facility Operating License Conditions.

The following requirement was relocated from the TS 6.1.1.8 during the conversion to ITS.

A training program for the fire brigade shall meet or exceed the requirements of Section 27 of the NFPA Code-i 975, except that training sessions may be held quarterly.

ACTIONS Al With the requirements for minimum station staffing not met, the minimum station staffin g levels shall be restored within 2 hours0.0833 days <br />0.0119 weeks <br />0.00274 months <br />.

OP/i/A/i 104/049 Page 2 of 5 Low Temperature Overpressure Protection (LTOP)

1. Purpose This procedure provides guidance to comply with Technical Specification (TS) 3.4.i2 and SLC 16.5.2 as well as provide protection from a low temperature overpr essure (LTOP) event.

2. Limits And Precautions 2.1 LTOP must be set per this procedure under the following plant conditions:

• MODE 3 when any RCS cold leg temperature is 325°F

• MODES 4, 5, and 6 when an RCS vent path capable of mitigating the most limiting LTOP event is NOT open 2.2 Conditions for which a dedicated LTOP Operator can compensate are shown graphically in Enclosure 4.13 (LTOP Requirements Logic Diagram).

NOTE: For purpose of performance of HPI Full Flow testing, LTOP controls are met by having both OTSG handholes removed.

2.3 The LTOP requirement of deactivating HPI can be considered met during HPI System testing when a LTOP vent path 3.6 square inches is open. Refer to Enclosure 4.5 (LTOP Vent Paths) for vent path flow area sizes.

2.4 Refer to Enclosure 4.8 (LTOP Pressure Instruments) for detailed inform ation concerning acceptable pressure instruments to be used during LTOP.

2.5 1N-121 (High Pressure Supply to Pzr) should remain closed when LTOP is required.

This valve has a permanent tag stating this.

2.6 A dedicated LTOP Operator is a compensatory measure allowed by TS 3.4.12 Condition F to monitor for an initiation of an LTOP event. Entry into this Condition is required any time a dedicated LTOP Operator is established.

2.7 Removing an ICCM Train from service renders the associated Pressu rizer level(s) for that ICCM train inoperable, and therefore the 260 inch audible Pressu rizer level alarm inoperable. A dedicated LTOP Operator will be required if the RCS

< 325°F and a vent path is NOT established.

OP/i/AR 104/049 Page 3 of 5 2.8 A dedicated LTOP Operator is required when RCS 325°F and any of the following administrative controls CANNOT be impl emented:

2.8.1 RCS closed (no LTOP vent path establishe d),

AND HPI pump operating and capable of injecting into RCS via 1HP-120 (RC VOLUME CONTROL),

AND 1HP-120 travel stop is inoperable.

2.8.2 RCS closed, AND RCS has deviated from pressure, temp erature, or level limits.

2.8.3 RCS closed, AND controls on use of high pressure Nitro gen NOT established.

2.8.4 RCS closed, AND number of available Pressurizer Heat er Banks NOT restricted.

2.8.5 RCS closed, AND OAC inoperable, 2.8.6 RCS closed, AND LTOP computer alarms inoperable.

2.8.7 RCS closed, AND any required audible Pressurizer level alarm inoperable.

2.8.8 RCS closed, AND the required audible RCS high press ure alarms inoperable.

2.9 When 1HP-120 travel stop is installed, available makeup flow is limited. RCS rate should be monitored and controlle cooldown d.

2.10 At least one HPI train shall be available as a makeup source from the BWST RCS vent equivalent to two SG primary whenever a handholes one SG primary manway is NOT established. {3}

OP/i/A/i 104/049 Page 4 of 5 2.11 OAC computer points:

2.11.1 When Computer Points are credited for LTOP, the Computer Pomts MUST be used from a Computer Display that indicates the Qual ity of the Computer Point.

The point Value must represent actual plant cond itions and the point Quality MUST indicate one of the following:

• GOOD

• INHB

• LALM

• HALM

• LOLO

• HIHI

• ALM

• DALM 2.11.2 Computer points 01 L3 154 (LTOP-RCS Pres sure High (Channel 1)) and O1L3 156 (LTOP-Pzr Lvi High (Channel 1)) are non-credited backup LTOP alarms fed from the RC LR PRESS TRAIN A instrument. Inoperability of these alarms requires no action.

2.11.3 Computer points 01L3 169 (LTOP-RCS Pressure High (Channel 2)) and 01L3 168 (LTOP-Pzr Lvi High (Channel 2))

are the RCS high pressure and 225 inch Pzr level alarms that are credited in the LTOP analysis. These alarms receive pressure input from the RC LR PRESS TRAiN B instrument which does NOT control the PORV. If eithe r of these computer points is inoperable, entry into TS 3.4.12 Condition F is required.

2.12 Enclosure 4.13 (LTOP Requirements Logi c Diagram) aids in determining if LTOP requirements are satisfied. This diagram shou ld be used as a reference when planning 3 performing activities that may affect LTOP.

2.12.1 Enclosure 4.13 (LTOP Requirements Logic Diag ram) should be verified as follows:

• Applicable plant/equipment configuration statu s should be circled.

• Logic diagram path should be traced out to verif y LTOP requirements are satisfied.

2.13 Enclosure 4.15 (Swapping LTOP Components) is available for swapping to alternate configuration for LTOP components after LTO P has been set, if needed.

SSF B 3.10 STANDBY SHUTDOWN FA 3.10.1 CILITY B 3.10.1 Standby Shutdown Facility (SSF)

BASES BACKGROUND The Standby Shutdown Facility (SS F) is designed as a standby system for use under certain emergency con ditions. The system provides additional defense in-depth pro tection for the health and safety of public by serving as a backup to exis the ting safety systems. The SSF is provided as an alternate means to achieve and maintain the unit in MODE 3 with average RCS temper ature 525°F (unless the initiating event causes the unit to be driven to a lower temperature) following CFR 50 Appendix R fire, sabotage, 10 turbine building flood, station blackou (SBO) and tornado missile events, t and is designed in accordance wit criteria associated with these events. h In that the SSF is a backup to existing safety systems, the sing le failure criterion is not required.

Failures in the SSF systems will not cause failures or inadvertent operations in other plant systems.

The SSF requires manual activati and can be activated if emergency on systems are not available.

The SSF is designed to maintain the reactor in a safe shutdown conditi for a period of 72 hours3 days <br />0.429 weeks <br />0.0986 months <br /> following on 10 CFR 50 Appendix R fire, turbine building flood, sabotage, SBO, or tornado missile events. This is accomplished by re-establishing and maintaining Reactor Coolant Pum Seal cooling; assuring natural circulat p ion and core cooling by maintainin the primary coolant system filled g to a sufficient level in the pressurize while maintaining sufficient second r ary side cooling water; and maintaining the reactor subcritical by isolating all sources of Reactor Coolant System (RCS) addition exc ept for the Reactor Coolant Makeu System which supplies makeup of p a sufficient boron concentration.

The SSF ASW System is a high hea d, high volume system designed to provide sufficient steam generator (SG) inventory for adequate decay heat removal for three units during a loss of normal AC power in conjunction with the loss of the nor mal and emergency feedwater systems. One motor driven SSF ASW pump, located in the SSF, serv all three units. The SSF ASW pum es p, two HVAC service water pumps, and the Diesel Service Water (DS W) pump share a common suction supply of lake water from the emb edded Unit 2 condenser circulating water (CCW) piping.

SSF B 3.10.1 BASES BACKGROUND The SSF ASW System is used to provide (continued) adequate cooling to maintain single phase RCS natural circ ulation flow in MODE 3 with an average RCS temperature 525°F (unless the initiating event causes the unit to be driven to a lower temperature).

In order to maintain single phase RCS natural circulation flow, an adequate number of Bank 2, Group B and C pressurizer heaters must be OPERABLE. These heaters are needed to compensate for ambient heat loss from the pressurizer.

As long as the temperature in the pressu rizer is maintained, RCS pressure will also be maintained. This will preclude hot leg voiding and ensure adequate natural circulation cool ing.

The SSF Portable Pumping System, whic h includes a submersible pump and a flow path capable of taking suction from the intake canal and discharging into the Unit 2 CCW line, is designed to provide a backup supply of water to the SSF in the eve nt of loss of CCW and subsequent loss of CCW siphon flow. The SSF Por table Pumping System is installed manually according to procedures.

The SSF RC Makeup System is design ed to supply makeup to the RCS in the event that normal makeup sys tems are unavailable. An SSF RC Makeup Pump located in the Reactor Building of each unit supplies makeup to the RCS should the normal makeup system flow and seal cooling become unavailable. The system is designed to ensure that sufficient borated water is provided from the spent fuel pools to allow the SSF to maintain all three units in MOD E 3 with average RCS temperature 525°F (unless the initiating event cau ses the unit to be driven to a lower temperature) for approximately 72 hou rs. An SSF RC Makeup Pump is capable of delivering borated water from the Spent Fuel Pool to the RC pump seal injection lines. A portion of this seal injection flow is used to makeup for reactor coolant pump sea l leakage while the remainder flows into the RCS to makeup for other RC S leakage (non LOCA).

The SSF Power System provides elec trical isolation of SSF equipment from non-SSF equipment. The SSF Power System includes 4160 VAC, 600 VAC, 208 VAC, 120 VAC and 125 VDC power. It consists of switchgear, a load center, motor con trol centers, panelboards, remote starters, batteries, battery chargers, inverters, a diesel generator (DG),

relays, control devices, and interconne cting cable supplying the appropriate loads.

The AC power system consists of 416 0 V switchgear OTS1; 600 V load center OXSF; 600 V motor control cen ters XSF, 1XSF, 2XSF, 3XSF, PXSF; 208 V motor control centers 1XS F, 1XSF-1, 2XSF, 2XSF-1, 3XS 3XSF-1; 120 V panelboards KSF, KSF F, C.

SSF B 3.10.1 BASES BACKGROUND SSF ASW pump should be operated whe (continued) n the diesel is operated to provide a load for the diesel. This is not a requirement for operability since the diesel could be operated to pro vide long term power to one or more units RC makeup pumps without ope rating the SSF ASW pump as long as a large load (SSF ASW pump )

is not added later (diesel desouping concern).

SSF Portable Pumping Supplies makeup water to the SSF AS W System, the SSF DSW System, and the SSF HVAC Service Water Sys tem after siphon flow I gravity flow and forced CCW flow are lost.

SSF Power System Other SSF Systems cannot operate wit hout receiving power from the diesel for SSF scenarios where power from U2 MFB is not available.

SSF Pressurizer Heaters Single phase RCS natural circulation flow cannot be maintained without the pressurizer heaters. The number of SSF heaters utilized is based on testing and calculations performed on a unit by unit basis to determine the minimum number of required hea ters needed to overcome actual pressurizer ambient losses. Since the heaters do not have their own action statement, the SSF ASW System is declared inoperable when the heaters are inoperable.

SSF RCS Isolation Valves (HP-3, HP

-4, HP-20, RC-4, RC-5, RC-6)

These valves do not have their own acti on statement. When they are inoperable, their corresponding SSF RC makeup system is considered inoperable.

SSF HVAC System Portions of the SSF HVAC System, con sisting of the SSF Air Conditioning (AC) and Ventilation Sys tems support the SSF Power System OPERABILITY. The SSF AC System, which includes the HVAC service water system and AC equipm ent (fan motors, compressors, condensers, and coils), must be ope rable to support SSF Power System operability. Since an inoperable SSF Power System results in all other SSF subsystems being inoperable, an SSF HVAC System operability problem that makes the SSF Power System inoperable also results in other SSF Subsystems being inoper able.

SSF B 3.10.1 BASES BACKGROUND The SSF AC System is designed to maintain the (continued) SSF Control Room, Computer Room, and Battery Rooms within their design temperature range. Elevated temperatures in the SSF Control Room and Computer Room could cause the SSF Power System to fail during an accident which requires operation of the SSF. The SSF AC System consists of two refrigeration circuits and an air handling unit. The requirements for the refrigeration circuits vary with outdoor air temperatu re. Depending on outdoor air temperature and Air Conditioning Syst em performance, the two refrigeration circuits may not be required to supp ort SSF power system OPERABILITY. The air handling unit is required to circulate air regardless of the number of refrigeration circu its required. Since the SSF HVAC service water pumps perform a redundan t function, only one of the two are required to be operable for the SSF HVA C service water system to be considered operable. The SSF Ventilatio n System, which supplies outside air to the Switchgear, Pump, HVAC and Diesel Generator Rooms, is composed of the following four subsystem s: Constant Ventilation, Summer Ventilation, On-line Ventilatio n, and Diesel Generator Engine Ventilation. These ventilation systems work together to provide cooling to the various rooms of the SSF under both standby and on-line modes. The Diesel Generator Engine Ventilation fan is required for operability of the SSF Power System. The six fans associated with the other three ventilation systems may or may not be required for SSF operability dependent upon outside air temperatu re. If the SSF AC System refrigeration circuits or one of the vent ilation fans fail, an engineering evaluation must be performed to determine if any of the SSF Systems or instrumentation are inoperable.

SSF Instrumentation System SSF Instrumentation is provided to monitor RCS pressure, RCS Loop A and B temperature (hot leg and cold leg), press urizer water level, and SG A and B water level. Indication is displayed on the SSF control panel.

APPLICABLE The SSF serves as a backup for existing safet SAFETY ANALYSES provide an alternate and y systems to independent means to achieve and maintain one, two, or three Oconee units in MODE 3 with average RCS temperature 525°F (unless the initiating even t causes the unit to be driven to a lower temperature) for up to 72 hours3 days <br />0.429 weeks <br />0.0986 months <br /> following 10 CFR 50 Appendix R fire, a turbine building flood, sabo tage, SBO, or tornado missile events (Refs. 1,6, 7, and 8).

The OPERABILITY of the SSF is consistent with the assumptions of the Oconee Probabilistic Risk Assessment (Ref

. 2). Therefore, the SSF satisfies Criterion 4 of 10 CFR 50.36 (Ref.

3).

SSF B 3.10.1 BASES LCO The SSF Instrumentation in Table B 3.10.1-1 and the following SSF Systems shall be OPERABLE:

a. SSF Auxiliary Service Water System;

b. SSF Portable Pumping System;

c. SSF Reactor Coolant Makeup System; and

d. SSF Power System.

An OPERABLE SSF ASW System includes pressurize r heaters capable of being powered from the SSF, and an SSF ASW pum p, piping, instruments, and controls to ensure a flow path capable of taking suction from the Unit 2 condenser circulating water (CCW) line and discharging into the secondary side of each SG. The minimum num ber of pressurizer heaters capable of being powered from the SSF is base d on maintaining RCS natural circulation flow. The number of SSF cont rolled pressurizer heaters needed to meet this requirement is dependent upon ambient heat loss from the pressurizer and the steam leakage rate from the pressurizer. The following table provides combina tion of SSF controlled pressurizer heaters versus steam space leakage rates that have been previously determined to meet Operability requirements for the SSF.

This is based on an Oconee calculation, with additiona l margin to prevent frequent revision. Engineering Input is needed to deter mine if other combinations of pressurizer heaters versus steam space leakage rate are acceptable.

An OPERABLE Reactor Coolant Makeup System includes an SSF RC Makeup pump, piping, instruments, and controls to ensure a flow path capable of taking suction from the spent fuel pool and discharging into the RCS. The following leakage limits are applicable for the SSF RC Makeup System to be considered OPERABLE:

Maximum Allowed Total Combined RCS Leakage for SSF RC Makeup System Operability The maximum allowed total combined RCS leakage is 24.7 GPM. A Units total combined RCS leakage shall be 24.7 GPM for its corresponding SSF RC Makeup System to be considered OPERABLE

.

Total Combined RCS leakage is based on Total RCS Leakage Rate +

Quench Tank Level Increase + Total RC Pump Seal Return Flow. Total RC Pump Seal Return Flow is determined by summing the seal return flow rate for all four RC Pumps. If the seal return flow rate for a RC Pump is not available, 3.35 GPM may be used as the seal return flow rate for the affected pump. This worst case seal leakage occurs when two seal stages are failed with the third seal stage leaking maximum outflow to the leakage system.

An OPERABLE SSF Power System includes the SSF DG, diesel suppor t

systems, 4160 VAC, 600 VAC, 208 VAC, 120 VAC, and 125 VDC systems. Only one 125 VDC SSF battery and its associated charger are required to be OPERABLE to support OPERABILITY of the 125 VDC system.

SSF B 3.10.1 BASES (continued)

APPLICABILITY The SSF System is required in MODES 1, 2, and 3 to provide an alternate means to achieve and maintain the unit in MODE 3 with average RCS temperature 525°F (unless the initiating event causes the unit to be driven to a lower temperature) follo wing 10 CFR 50 Appendix R fire, turbine building flood, sabotage, SBO and tornado missile events.

The safety function of the SSF is to achie ve and maintain the unit in MODE 3 with average RCS temperature 525°F (unless the initiating event causes the unit to be driven to a lowe r temperature); therefore, this LCO is not applicable in MODES 4, 5, or 6.

ACTIONS The exception for LCO 3.0.4, provided in the Note of the Actions, permits entry into MODES 1, 2, and 3 with the SSF not OPERABLE. This is acceptable because the SSF is not required to support normal operation of the facility or to mitigate a design basis accid ent.

A.1, B.1, C.1, D.1, and E.1 With one or more of the SSF Systems inop erable or the required SSF instrumentation of Table B 3.10.1-1 inoperab le, the SSF is in a degraded condition and the system(s) or instrumentation must be restored to OPERABLE status within 7 days. The 7 day Completion Time is based on the low probability of an event occurring which would require the SSF to be utilized.

F. 1 If the Required Action and associated Com pletion Time of Condition A, B, C, D, or E are not met when SSF Systems or Instrumentation are inoperable due to maintenance, the unit may continue to operate provided that the SSF is restored to OPERAB LE status within 45 days from discovery of initial inoperability.

This Completion Time is modified by a Note that indicates that the SSF shall not be in Condition F for more than a total of 45 days in a calendar OCONEE UNITS 1, 2, & 3 B 3.10.1-9 BASES REVISION DATED 05/18/10

SSF B 3.10.1 BASES ACTIONS F.1 (continued) year. This includes the 7 day Completion Time that leads to entry into Condition F. For example, if the SSF ASW System is inoperable for 10 days, the 45 day special inoperability period is reduced to 35 days. If the SSF ASW System is inoperable for 6 days, Condition A applies and there is no reduction in the 45 day allowance. The limit of 45 days per calendar year minimizes the number and duration of extended outages associated with exceeding the 7 day Completion Time of a Condition.

G.1 and G.2 If the Required Action and associated Completion Time of Condition F are not met or if the Required Action and associated Completion Time of Condition A, B, C, D, or E are not met for reasons other than Condition F, the unit must be brought to a MODE in which the LCO does not apply.

To achieve this status, the plant must be brought to MODE 3 within 12 hours0.5 days <br />0.0714 weeks <br />0.0164 months <br /> and MODE 4 within 84 hours3.5 days <br />0.5 weeks <br />0.115 months <br />. The allowed Completion Times are appropriate, to reach the required unit conditions from full power conditions in an orderly manner and without challenging plant systems, considering a three unit shutdown may be required.

SURVEILLANCE SR 3.10.1.1 REQUIREMENTS Performance of the CHANNEL CHECK once every 7 days for each required instrumentation channel ensures that a gross failure of instrumentation has not occurred. A CHANNEL CHECK is normally a comparison of the parameter indicated on one channel with a similar parameter on other channels. It is based on the assumption that instrument channels monitoring the same parameter should read approximately the same value. Significant deviations between the two instrument channels could be an indication of excessive instrument drift in one of the channels or of something even more serious. A CHANNEL CHECK will detect gross channel failure; therefore, it is key in verifying that the instrumentation continues to operate properly between each CHANNEL CALIBRATION. This SR is modified by a Note to indicate that it is not applicable to the SSF RCS temperature instrument channels, which are common to the RPS RCS temperature instrument channels and are normally aligned through a transfer isolation device to each Unit control room. The instrument string to the SSF control room is checked and calibrated every 18 months Agreement criteria are determined based on a combination of the channel instrument uncertainties, including indication and readability.

REQUIREMENTS channel is outside the criteria, it may be an indication that the sensor or the signal processing equipment has drifted outside its limit. If the channels are within the criteria, it is an indication that the channels are OPERABLE. If the channels are normally off scale during times when surveillance is required, the CHANNEL CHECK will only verify that they are off scale in the same direction. Off scale low current loop channels are verified to be reading at the bottom of the range and not failed downscale.

The Frequency is based on unit operating experience that demonstrates channel failure is rare.

SR 3.10.1.2 Verifying battery terminal voltage while on float charge for the batteries helps to ensure the effectiveness of the charging system and the ability of the batteries to perform their intended function. Float charge is the condition in which the charger is supplying the continuous charge required to overcome the internal losses of a battery (or battery cell) and maintain the battery (or a battery cell) in a fully charged state. The voltage requirements are based on the nominal design voltage of the battery and are consistent with the initial voltages assumed in the battery sizing calculations. The 7 day Frequency is consistent with manufacturer recommendations and IEEE-450 (Ref. 4).

SR 3.10.1.3 and 3.10.1.4 SR 3.10.1.3 provides verification that the level of fuel oil in the day tank is at or above the level at which fuel oil is automatically added. The level is expressed as an equivalent volume in gallons. The day tank is sized based on the amount of fuel oil required to successfully start the DG and to allow for orderly shutdown of the DG upon loss of fuel oil from the main storage tank.

SR 3.10i.4 provides verification that there is an adequate inventory of fuel oil in the storage tanks to support SSF DG operation for 72 hours3 days <br />0.429 weeks <br />0.0986 months <br /> at full load. The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> period is sufficient time to place the unit in a safe shutdown condition The 31 day Frequency for these SRs is adequate to assure that a sufficient supply of fuel oil is available, since low level alarms are provided and unit operators would be aware of any large uses of fuel oil during this period.

SSF B 3.10.1 BASES SURVEILLANCE SR 3.10.1.5 REQUIREMENTS (continued) The SR requires the DG to start (normal or emergency) from standby conditions and achieve required voltage and frequency. Standby conditions for a DG means that the diesel engine coolant and oil are being continuously circulated and temperature is being maintained consistent with manufacturer recommendations. This SR is modified by a Note to indicate that all DG starts for this Surveillance may be preceded by an engine prelube period and followed by a warmup period prior to loading. This minimizes wear on moving parts that do not get lubricated when the engine is running.

The 31 day Frequency is consistent with Regulatory Guide 1.9 (Ref. 5).

This Frequency provides adequate assurance of DG OPERABILITY, while minimizing degradation resulting from testing.

SR 3.10.1.6 This Surveillance ensures that sufficient air start capacity for the SSF DG is available, without the aid of the refill compressor. The SSF DG air start system is equipped with four air storage tanks. Each set of two tanks will provide sufficient air to start the SSF DG a minimum of three successive times without recharging. The pressure specified in this SR is intended to reflect the lowest value at which the three starts can be accomplished.

The 31 day Frequency takes into account the capacity, capability, redundancy, and diversity of the AC sources.

SR 3.10.1.7 This Surveillance demonstrates that the fuel oil transfer pump automatically starts and transfers fuel oil from the underground fuel oil storage tank to the day tank. This is required to support continuous operation of SSF DG. This Surveillance provides assurance that the fuel oil transfer pump is OPERABLE, the fuel oil piping system is intact, the fuel delivery piping is not obstructed, and the controls and control systems for automatic fuel transfer systems are OPERABLE.

The 92 day Frequency is considered acceptable based on operating experience.

SSF B 3.10.1 BASES SURVEILLANCE SR 3.10.1.8 REQUIREMENTS (continued) A sample of fuel oil is required to be obtained from the SSF day tank and underground fuel oil storage tank in accordance with the Diesel Fuel Oil Testing Program in order to ensure that fuel oil viscosity, water, and sediment are within the limits of the Diesel Fuel Oil Testing Program.

The 92 day Frequency is considered acceptable based on operating experience related to diesel fuel oil quality.

SR 3.10.1.9 This Surveillance verifies that the SSF DG is capable of synchronizing with the offsite electrical system and accepting loads greater than or equal to the equivalent of the maximum expected accident loads. A minimum run time of 60 minutes is required to stabilize electrical loads, while minimizing the time that the DG is connected to the offsite source.

Although no power factor requirements are established by this SR, the DG is normally operated at a power factor between 0.8 lagging and 1.0.

The 0.8 value is the design rating of the machine, while the 1.0 is an operational limitation to ensure circulating currents are minimized. The load band is provided to avoid routine overloading of the DG. Routine overloading may result in more frequent teardown inspections in accordance with vendor recommendations in order to maintain DG OPERABILITY.

The normal 92 day Frequency for this Surveillance is consistent with Regulatory Guide 1.9 (Ref. 5).

This SR is modified by three Notes. Note 1 indicates that diesel engine runs for this Surveillance may include gradual loading, as recommended by the manufacturer, so that mechanical stress and wear on the diesel engine are minimized. Note 2 states that momentary transients because of changing bus loads do not invalidate this test. Similarly, momentary power factor transients above the limit will not invalidate the test. Note 3 indicates that all DG starts for this Surveillance may be preceded by an engine prelube period and followed by a warmup period prior to loading.

This minimizes wear on moving parts that do not get lubricated.

The presence of physical damage or deterioration does not necessarily represent a failure of this SR, provided an evaluation determines that the physical damage or deterioration does not affect the OPERABILITY of the battery (its ability to perform its design function).

The 12 month Frequency for this SR is consistent with IEEE-450 (Ref. 4),

The discharge rate and test length correspond to the design duty cycle requirements. The design basis discharge time for the SSF battery is one hour.

The Surveillance Frequency for this test is 12 months. This Frequency is considered acceptable based on operating experience.

SR 3.10.1.13 CHANNEL CALIBRATION is a complete check of the instrument channel, including the sensor. The test verifies that the channel responds to a measured parameter within the necessary range and accuracy.

CHANNEL CALIBRATION leaves the channel adjusted to account for instrument drift to ensure that the instrument channel remains operational between successive tests. CHANNEL CALIBRATION shall find that measurement errors and bistable setpoint errors are within the assumptions of the setpoint analysis. CHANNEL CALIBRATIONS must be performed consistent with the assumptions of the setpoint analysis.

This Frequency is justified by the assumption of an 18 month calibration interval to determine the magnitude of equipment drift in the setpoint analysis.
