Recirculation Loops Operating B 3.4.1 BASES APPLICABLE margins during abnormal operational transients (Ref. 2),

SAFETY ANALYSIS which are analyzed in Chapter 14 of the UFSAR.

(continued)

A plant specific LOCA analysis has been performed assuming only one operating recirculation loop. This analysis has demonstrated that, in the event of a LOCA caused by a pipe break in the operating recirculation loop, the Emergency Core Cooling System response will provide adequate core cooling, provided the APLHGR requirements are modified accordingly (Ref. 3).

The transient analyses of Chapter 14 of the UFSAR have also been performed for single recirculation loop operation (Ref. 3) and demonstrate sufficient flow coastdown characteristics to maintain fuel thermal margins during the abnormal operational transients analyzed provided the MCPR requirements are modified. During single recirculation loop operation, modification to the Reactor Protection System (RPS) average power range monitor (APRM) and the control rod block instrumentation Allowable Values are also required to account for the different relationships between recirculation drive flow and reactor core flow. The APLHGR and MCPR limits for single loop operation are specified in the COLR. The APRM Neutron Flux-High (Flow Biased)

Allowable Value is in LCO 3.3.1.1, "Reactor Protection System (RPS) Instrumentation." The Rod Block Monitor-Upscale Allowable Value is specified in LCO 3.3.2.1, "Control Rod Block Instrumentation."

Operation of the Reactor Water Recirculation System also ensures adequate core flow at higher power levels such that conditions conducive to the onset of thermal hydraulic instability are avoided. The UFSAR Section 16.6 (Ref. 4) requires protection of fuel thermal safety limits from conditions caused by thermal hydraulic instability. Thermal hydraulic instabilities can result in power oscillations which could result in exceeding the MCPR Safety Limit. The MCPR Safety Limit is set such that 99.9% of the fuel rods avoid boiling transition if the limit is not violated (refer to the Bases for SL 2.1.1.2). Implementation of operability requirements for avoidance of, and protection from thermal hydraulic instability, consistent with the BWR Owners' Group Long-Term Stability Solution Option I-D (Refs. 5 and 6) IL_

provides assurance that power oscillations are either prevented or can be readily detected and suppressed without exceeding the specified acceptable fuel design limits. To (continued)

(continued) "Exclusion Region" is calculated using the approved methodology specified in Specification 5.6.5. The resulting "Exclusion Region" may change each fuel cycle and is therefore specified in the COLR. Entries into the "Exclusion Region" may occur as a result of an abnormal event, such as a single recirculation pump trip, loss of feedwater heating, or be required to prevent equipment damage.

The core-wide mode of oscillation in the neutron flux is more readily detected (and suppressed) than the regional mode of oscillation due to the spatial averaging of the Average Power Range Monitor (APRM). The Option I-D analysis for JAFNPP (Ref. 7) demonstrates that this protection is provided at a high statistical confidence level for regional mode oscillations. Reference 7 also demonstrates that the core-wide mode of oscillation is more likely to occur rather than regional oscillations due to the large single-phase pressure drop associated with the small fuel inlet orifice diameters.

Recirculation loops operating satisfies Criterion 2 of 10 CFR 50.36(c)(2)(ii) (Ref. 8).

LCO Two recirculation loops are required to be in operation with their flows matched within the limits specified in SR 3.4.1.2 to ensure that during a LOCA caused by a break of the piping of one recirculation loop the assumptions of the LOCA analysis are satisfied. Alternatively, with only one recirculation loop in operation, modifications to the required APLHGR limits (LCO 3.2.1, "AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR)"), MCPR limits (LCO 3.2.2, "MINIMUM CRITICAL POWER RATIO (MCPR)"), APRM Neutron Flux High (Flow Biased) Allowable Value (LCO 3.3.1.1) and the Rod Block Monitor-Upscale Allowable Value (LCO 3.3.2.1) must be applied to allow continued operation consistent with the assumptions of Reference 3. In addition, during two-loop and single-loop operation, the combination of core flow and THERMAL POWER must be outside the Exclusion Region of (continued)

JAFNPP B 3.4-4 Revision J

Recircul ation Loops Operating B 3.4.1 BASES LCO the power-to-flow map specified in the COLR to ensure core (continued) thermal-hydraulic instability does not occur.

APPLICABILITY In MODES 1 and 2, requirements for operation of the Reactor Water Recirculation System are necessary since there is considerable energy in the reactor core, core thermal hydraulic instability may occur, and the limiting design basis transients and accidents are assumed to occur.

In MODES 3, 4, and 5, the consequences of an accident are reduced and the coastdown characteristics of the recirculation loops are not important.

ACTIONS A.1 With the reactor operating at core flow and THERMAL POWER conditions within the Exclusion Region of the power-to-flow map it is in a condition where thermal-hydraulic instabilities are conservatively predicted to occur, and must be brought to an operating state where such instabilities are not predicted to occur. To achieve this status, action must be taken immediately to exit the Exclusion Region. This is accomplished by inserting control rods or increasing core flow such that the combination of THERMAL POWER and core flow move to a point outside the Exclusion Region. The action is considered sufficient to preclude core thermal-hydraulic instabilities which could challenge the MCPR safety limit. The starting of a recirculation pump is not used as a means to exit the Exclusion Region of the power-to-flow map. Starting an idle recirculation pump could result in a reduction in inlet core enthalpy and enhance conditions necessary for thermal hydraulic instabilities.

B.1 With the requirements of the LCO not met for reasons other than Condition A, the recirculation loops must be restored to operation with matched flows within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. A recirculation loop is considered not in operation when the (continued)

JAFNPP B 3.4-5 Revision J

Recirculation Loops Operating B 3.4.1 BASES ACTIONS C.1 (continued) the recirculation loops are not required to be operating because of the reduced severity of DBAs and minimal dependence on the recirculation loop coastdown characteristics. The allowed Completion Time of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is reasonable, based on operating experience, to reach MODE 3 from full power conditions in an orderly manner and without challenging plant systems.

SURVEILLANCE SR 3.4.1.1 REQUIREMENTS This SR ensures the combination of core flow and THERMAL POWER are within appropriate limits to prevent uncontrolled thermal-hydraulic oscillations. At low recirculation flows and high reactor power, the reactor exhibits increased susceptibility to thermal-hydraulic instability. The power to-flow map specified in the COLR is based on guidance provided in Reference 7. The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Frequency is based on operating experience and the operator's knowledge of the reactor status, including significant changes in THERMAL POWER and core flow.

This SR is modified by a Note that requires this Surveillance to be performed only in MODE 1 because the APRM Neutron Flux-High (Startup) Function in LCO 3.3.1.1 will prevent operation in the Exclusion Region while in MODE 2.

SR 3.4.1.2 This SR ensures the recirculation loops are within the allowable limits for mismatch. At low core flow (i.e.,

< 70% of rated core flow), the MCPR requirements provide larger margins to the fuel cladding integrity Safety Limit such that the potential adverse effect of early boiling transition during a LOCA is reduced. A larger flow mismatch can therefore be allowed when core flow is < 70% of rated core flow. The recirculation loop jet pump flow, as used in this Surveillance, is the summation of the flows from all of the jet pumps associated with a single recirculation loop.

The mismatch is measured in terms of percent of rated core flow. If the flow mismatch exceeds the specified limits, (continued)

REQUIREMENTS Condition B must be entered, and the loop with the lower flow must be declared "not in operation". (However, for the purpose of performing SR 3.4.1.1, the flow rate of both loops shall be used.) The SR is not required when only one loop is in operation since the mismatch limits are meaningless during single loop or natural circulation operation. The Surveillance must be performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after both loops are in operation.

Jet Pumps B 3.4.2 BASES APPLICABLE The capability of reflooding the core to two-thirds core SAFETY ANALYSES height is dependent upon the structural integrity of the jet (continued) pumps. If the structural system, including the beam holding a jet pump in place, fails, jet pump displacement and performance degradation could occur, resulting in an increased flow area through the jet pump and a lower core flooding elevation. This could adversely affect the water level in the core during the reflood phase of a LOCA as well as the assumed blowdown flow during a LOCA.

Jet pumps satisfy Criterion 2 of 10 CFR 50.36(c)(2)(ii)

(Ref. 2).

LCO The structural failure of any of the jet pumps could cause significant degradation in the ability of the jet pumps to allow reflooding to two-thirds core height during a LOCA.

OPERABILITY of all jet pumps is required to ensure that operation of the Reactor Water Recirculation System will be consistent with the assumptions used in the licensing basis analysis (Ref. 1).

APPLICABILITY In MODES 1 and 2, the jet pumps are required to be OPERABLE since there is a large amount of energy in the reactor core and since the limiting DBAs are assumed to occur in these MODES. This is consistent with the requirements for operation of the Reactor Water Recirculation System (LCO 3.4.1).

In MODES 3, 4, and 5, the Reactor Water Recirculation System is not required to be in operation, and when not in operation, sufficient flow is not available to evaluate jet pump OPERABILITY.

ACTIONS A.1 An inoperable jet pump can increase the blowdown area and reduce the capability to reflood during a design basis LOCA.

If one or more of the jet pumps are inoperable, the plant must be brought to a MODE in which the LCO does not apply.

S/RVs B 3.4.3 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.3 Safety/Relief Valves (S/RVs)

BASES BACKGROUND The ASME Boiler and Pressure Vessel Code (Ref. 1) requires the reactor pressure vessel be protected from overpressure during upset conditions by self-actuated safety valves. As part of the nuclear pressure relief system, the size and number of S/RVs are selected such that peak pressure in the nuclear system will not exceed the ASME Code limits for the reactor coolant pressure boundary (RCPB).

The S/RVs are located on the main steam lines between the reactor vessel and the first isolation valve within the drywell. Each S/RV discharges steam through a discharge line to a point below the minimum water level in the suppression pool.

The S/RVs can actuate by either of two modes: the safety mode or the relief mode. However, for the purposes of this LCO, only the safety mode is required. In the safety mode (or spring mode of operation), the spring loaded pilot valve opens when steam pressure at the valve inlet overcomes the spring force holding the pilot valve closed. Opening the pilot valve allows a pressure differential to develop across the main valve piston and opens the main valve. This satisfies the Code requirement.

Each S/RV can be opened manually in the relief mode from the control room by its associated two-position switch. If one of these switches is placed in the open position the logic output will energize the associated S/RV solenoid control valve directing the pneumatic supply to open the valve.

Seven of these S/RV solenoid control valves can also be energized by the relay logic associated with the Automatic Depressurization System (ADS). ADS requirements are specified in LCO 3.5.1, "ECCS-Operating." In addition each S/RV can be manually operated from another control switch located at the ADS auxiliary panel located outside the control room. These switches will energize a different S/RV solenoid control valve. The details of S/RVs pneumatic supply and mechanical operation in the relief mode are described in Reference 2.

S/RVs B 3.4.3 BASES (continued)

APPLICABLE The overpressure protection system must accommodate the most SAFETY ANALYSES severe pressurization transient. Evaluations have determined that the most severe transient is the closure of all main steam isolation valves (MSIVs), followed by reactor scram on high neutron flux (i.e., failure of the direct scram associated with MSIV position) (Refs. 3 and 4). For the purpose of the analyses (Ref. 4), nine S/RVs are assumed to operate in the safety mode. The analysis results demonstrate that nine S/RVs are capable of maintaining reactor pressure below the ASME Code limit of 110% of vessel design pressure (110% x 1250 psig = 1375 psig). This LCO helps to ensure that the acceptance limit of 1375 psig (at the vessel bottom) is met during the most severe pressurization transient.

From an overpressure standpoint, the design basis events are bounded by the MSIV closure with flux scram event described above. Reference 5 discusses additional events that are expected to actuate the S/RVs.

S/RVs satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii)

(Ref. 6).

LCO The safety function of nine S/RVs are required to be OPERABLE to satisfy the assumptions of the safety analysis (Refs. 3 and 4). The requirements of this LCO are applicable only to the capability of the S/RVs to mechanically open to relieve excess pressure when the lift setpoint is exceeded (safety function).

The single nominal S/RV setpoint is established (Ref. 2) to ensure that the ASME Code limit on peak reactor pressure is satisfied. The ASME Code specifications require the lowest safety valve setpoint to be at or below vessel design pressure (1250 psig) and the highest safety valve to be set so that the total accumulated pressure does not exceed 110%

of the design pressure for overpressurization conditions.

The single nominal S/RV setpoint is set below the RPV design pressure (1250 psig) in accordance with ASME Code requirements. The transient evaluations in Reference 5 are based on this single setpoint, but also include the additional uncertainties of +/- 3% of the nominal setpoint to provide an added degree of conservatism.

SURVEILLANCE SR 3.4.3.1 REQU IREMENTS This Surveillance requires that the required S/RVs open at the pressures assumed in the safety analysis of References 3 and 4. The demonstration of the S/RV safety function lift settings must be performed during shutdown, since this is a bench test, to be done in accordance with the Inservice Testing Program. The lift setting pressure shall correspond to ambient conditions of the valves at nominal operating temperatures and pressures. The S/RV setpoint is +/- 3% for OPERABILITY: however, the valves are reset to +/- 1% during the Surveillance to allow for drift.

SR 3.4.3.2 A manual actuation of each required S/RV is performed while bypassing main steam flow to the condenser and observing

Ž 10% closure of the turbine bypass valves to verify that, mechanically, the valve is functioning properly and no blockage exists in the valve discharge line. This can also be demonstrated by the response of the turbine control valves, by a change in the measured steam flow, or by any other method suitable to verify steam flow. Adequate reactor steam dome pressure must be available to perform this test to avoid damaging the valve. Also, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the S/RVs divert steam flow upon opening. Sufficient time is therefore allowed after the required pressure and flow are achieved to perform this test. Adequate pressure at which this test is to be performed is 970 psig (the pressure consistent with vendor recommendations). Adequate steam flow is represented by two or more turbine bypass valves open, or total steam flow 2 106 lb/hr. These conditions will require the plant to be in MODE 1, which has been shown to be an acceptable condition to perform this test. This test causes a small neutron flux transient which may cause a scram in MODE 2 while operating close to the Average Power Range Monitors Neutron Flux-High (Startup) Allowable Value.

Plant startup is allowed prior to performing this test because valve OPERABILITY and the setpoints for overpressure protection are verified, per ASME Code requirements, prior to valve installation. Therefore, this SR is modified by a Note that states the Surveillance is not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure and (continued)

If a valve fails to actuate due only to the failure of the solenoid but is capable of opening on overpressure, the safety function of the S/RV is considered OPERABLE.

The 24 month on a STAGGERED TEST BASIS Frequency ensures that each solenoid for each S/RV is alternately tested. The 24 month Frequency was developed based on the S/RV tests required by the ASME Boiler and Pressure Vessel Code,Section XI (Ref. 7). Operating experience has shown that these components usually pass the Surveillance when performed at the 24 month Frequency. Therefore, the Frequency is acceptable from a reliability standpoint.

DISCUSSION OF CHANGES ITS: 3.4.5 - RCS LEAKAGE DETECTION INSTRUMENTATION TECHNICAL CHANGES - LESS RESTRICTIVE (SPECIFIC)

L5 (continued)

Detection Instrumentation, is to provide instrumentation requirements for early identification of unidentified leakage, the drywell equipment drain sump monitoring system requirements of CTS 3.6.D.4, 3.6.D.5, 4.6.D.4, Table 3.2-5, and Table 4.2-5 are proposed to be deleted. The drywell equipment drain sump monitoring system does not necessarily relate directly to the Leakage requirements (other means to quantify identified leakage are available, such as equipment drain sump pump-out times). Control of the availability of, and necessary compensatory activities if not available, for indications and monitoring instruments are addressed by plant operational procedures and policies. The requirement to demonstrate Leakage is within limits is still maintained in SR 3.4.4.1. As a result, the requirement for a means to quantify identified leakage is adequately addressed by the requirements of ITS 3.4.4 and associated SR 3.4.4.1. Therefore, explicit requirements for the drywell equipment drain sump monitoring system instrumentation are not required.

L6 A Note has been added to CTS 4.6.D.4 (Note to ITS 3.4.5 Surveillance Requirements) to allow a channel to be inoperable for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> solely for performance of required Surveillances provided the other Leakage Detection System channel is OPERABLE. The 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> testing allowance has been granted by the NRC in Technical Specification amendment for Georgia Power Company's Hatch Unit 1 (Amendment 185) and Unit 2 (Amendment 125), in the ITS amendment for Washington Public Power Supply System Unit 2 (amendment 149), Nine Mile Point Unit 2 (Amendment 91, the ITS amendment), and LaSalle Units 1 and 2 (Amendments 147/133, respectively, the ITS amendments). The NRC has also granted this allowance in other topical reports for the Reactor Protection System, Emergency Core Cooling System, and Isolation System Instrumentation.

The 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> testing allowance does not significantly reduce the probability of properly monitoring leakage since the other channel must be OPERABLE for this allowance to be used.

W Insert BKGD As the water which has been collected in the drywell floor drain sump is pumped out, the discharge flow is measured and total flow indicated by a flow integrator. The unidentified LEAKAGE and unidentified LEAKAGE increase are periodically calculated from this flow integrator. A flow recorder continually plots time versus discharge flow rate: an increase in leakage rate is also detectable by an increase in sump discharge flow time and an increased frequency in discharge flow cycles.

Sb Insert BKGD-3 The sensitivity and response time of the system are a function of: location of the leak; amount of fission or corrosion product remaining in the atmosphere where they may be measured; plateout of these products in the sampling lines; effectiveness of the drywell coolers in reducing airborne concentrations; and the power level at the time of leakage occurrence (Ref. 3).

The drywell continuous atmospheric gaseous monitoring system, however, will not alarm for reactor coolant leaks (since there is no retention factor for noble gases in the reactor coolant). The drywell continuous atmospheric gaseous monitoring system will respond only if the leak is in the steam portion of the RCPB. Larger changes in LEAKAGE rates can be detected in proportionally shorter times (Ref. 5).

RCS Leakage Detection Instrumentation B 3.4.5 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.5 RCS Leakage Detection Instrumentation BASES BACKGROUND The JAFNPP design basis (Ref. 1) requires means for detecting and, to the extent practical, identifying the location of the source of RCS LEAKAGE. Reliable means are provided to detect leakage from the reactor coolant pressure boundary (RCPB) before predetermined limits are exceeded (Refs. 2 and 3).

Limits are established on abnormal leakage so that corrective action can be taken before unacceptable results occur (Ref. 4). Leakage detection systems for the RCS are provided to alert the operators when leakage rates above normal background levels are detected and also to supply quantitative measurement of leakage rates. The Bases for LCO 3.4.4, "RCS Operational LEAKAGE," discuss the limits on RCS LEAKAGE rates.

Systems for separating the LEAKAGE of an identified source from an unidentified source are necessary to provide prompt and quantitative information to the operators to permit them to take immediate corrective action.

LEAKAGE from the RCPB inside the drywell is detected by at least one of two independently monitored variables, such as sump pump flow and drywell gaseous and particulate radioactivity levels. The primary means of quantifying LEAKAGE in the drywell is the drywell floor drain sump monitoring system.

The drywell floor drain sump monitoring system monitors the LEAKAGE collected in the floor drain sump. This unidentified LEAKAGE consists of LEAKAGE from control rod drives, valve flanges or packings, floor drains, the Reactor Building Closed Loop Cooling Water System, and drywell air cooling unit condensate drains, and any LEAKAGE not collected in the drywell equipment drain sump. The drywell floor drain sump has instrumentation that supply level indicators in the control room.

The floor drain sump level instrumentation include switches that start and stop the sump pumps where required. A timer starts each time the sump is pumped down to the low level setpoint. If the sump fills to the high level setpoint (continued)

JAFNPP B 3.4-25 Revision J

RCS Leakage Detection Instrumentation B 3.4.5 BASES BACKGROUND before the timer ends, an alarm sounds in the control room, (continued) indicting a LEAKAGE rate into the sump in excess of a preset limit. In addition, the pump-out time is monitored and whenever the pump-out time exceeds a preset interval (indicating an increase in leak rate) an alarm annunciates in the control room.

As the water which has been collected in the drywell floor drain sump is pumped out, the discharge flow is measured and total flow indicated by a flow integrator. The unidentified LEAKAGE and unidentified LEAKAGE increase are periodically calculated from this flow integrator. A flow recorder continually plots time versus discharge flow rate: an increase in leakage rate is also detectable by an increase in sump discharge flow time and an increased frequency in discharge flow cycles.

The drywell continuous atmospheric monitoring system continuously monitors the drywell atmosphere for airborne particulate and gaseous radioactivity. A sudden increase of radioactivity, which may be attributed to RCPB steam or reactor water LEAKAGE, is annunciated in the control room.

The drywell atmosphere particulate and gaseous radioactivity monitoring system is not capable of quantifying LEAKAGE rates. The sensitivity and response time of the system are a function of: location of the leak; amount of fission or corrosion product remaining in the atmosphere where they may be measured; plateout of these products in the sampling lines; effectiveness of the drywell coolers in reducing airborne concentrations; and the power level at the time of leakage occurrence (Ref. 3). The drywell continuous atmospheric particulate monitoring system is sufficiently sensitive to detect a reactor coolant leak of 1 gpm within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. The drywell continuous atmospheric gaseous monitoring system, however, will not alarm for reactor coolant leaks (since there is no retention factor for noble gases in the reactor coolant). The drywell continuous atmospheric gaseous monitoring system will respond only if the leak is in the steam portion of the RCPB. Larger changes in LEAKAGE rates can be detected in proportionally shorter times (Ref. 5).

APPLICABLE A threat of significant compromise to the RCPB exists if the SAFETY ANALYSES barrier contains a crack that is large enough to propagate rapidly. LEAKAGE rate limits are set low enough to detect the LEAKAGE emitted from a single crack in the RCPB (Refs. 6 b (continued)

JAFNPP B 3.4-26 Revision J

RCS Leakage Detection Instrumentation B 3.4.5 BASES APPLICABLE and 7). Each of the leakage detection systems inside the SAFETY ANALYSES drywell is designed with the capability of detecting LEAKAGE (continued) less than the established LEAKAGE rate limits and providing appropriate alarm or indication of excess LEAKAGE in the control room.

A control room alarm or indication allows the operators to evaluate the significance of the indicated LEAKAGE and, if necessary, shut down the reactor for further investigation and corrective action. The allowed LEAKAGE rates are well below the rates predicted for critical crack sizes (Refs. 6 and 7). Therefore, these actions provide adequate response before a significant break in the RCPB can occur.

RCS leakage detection instrumentation satisfies Criterion 1 of 10 CFR 50.36(c)(2)(ii) (Ref. 8).

LCO The drywell floor drain sump monitoring system is required to quantify the unidentified LEAKAGE from the RCS. Thus, for the system to be considered OPERABLE, the flow monitoring portion of the system must be OPERABLE since this portion is capable of quantifying unidentified LEAKAGE from the RCS. The other monitoring systems (one channel each of the drywell continuous atmospheric particulate and drywell continuous atmospheric gaseous monitoring systems) provide early alarms to the operators so closer examination of other detection systems will be made to determine the extent of any corrective action that may be required. With the leakage detection systems inoperable, monitoring for LEAKAGE in the RCPB is degraded.

APPLICABILITY In MODES 1, 2, and 3, leakage detection systems are required to be OPERABLE to support LCO 3.4.4. This Applicability is consistent with that for LCO 3.4.4.

ACTIONS A.1 With the drywell floor drain sump monitoring system inoperable, no other form of sampling can provide the equivalent information to quantify leakage. However, the drywell continuous atmospheric monitors will provide indication of changes in leakage.

JAFNPP B 3.4-27 Revision J

RCS Leakage Detection Instrumentation B 3.4.5 BASES ACTIONS A.1 (continued)

With the drywell floor drain sump monitoring system inoperable, but with RCS unidentified and total LEAKAGE being determined every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> (SR 3.4.4.1), operation may continue for 30 days. The 30 day Completion Time of Required Action A.1 is acceptable, based on operating experience, considering the multiple forms of leakage detection that are still available. Required Action A.1 is modified by a Note that states that the provisions of LCO 3.0.4 are not applicable. As a result, a MODE change is allowed when the drywell floor drain sump monitoring system is inoperable. This allowance is provided because other instrumentation is available to monitor RCS leakage.

B.1 With one required drywell continuous atmospheric monitoring channel inoperable, SR 3.4.5.1 must be performed every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for the remaining OPERABLE drywell continuous atmospheric monitoring channel to provide periodic information of activity in the drywell at a more frequent interval than the routine Frequency of SR 3.4.5.1. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> interval provides periodic information that is adequate to detect LEAKAGE and recognizes that other forms of leakage detection are available. However, this Required Action is modified by a Note that allows this action to be not applicable if both drywell continuous atmospheric monitoring systems are inoperable. Consistent with SR 3.0.1, Surveillances are not required to be performed on inoperable equipment.

C.1 and C.2 With both required gaseous and particulate drywell continuous atmospheric monitoring channels inoperable, grab samples of the drywell atmosphere must be taken and analyzed to provide periodic leakage information. Provided a sample is obtained and analyzed once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, the plant may be operated for up to 30 days to allow restoration of at least one of the two monitors.

The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> interval provides periodic information that is adequate to detect LEAKAGE. The 30 day Completion Time for restoration recognizes that at least one other form of leakage detection is available.

JAFNPP B 3.4-28 Revision J

RCS Leakage Detection Instrumentation B 3.4.5 BASES ACTIONS C.1 and C.2 (continued)

The Required Actions are modified by a Note that states that the provisions of LCO 3.0.4 are not applicable. As a result, a MODE change is allowed when both the gaseous and particulate drywell continuous atmospheric monitoring systems are inoperable. This allowance is provided because other instrumentation is available to monitor RCS leakage.

D.1 and D.2 If any Required Action and associated Completion Time of Condition A or B cannot be met, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to perform the actions in an orderly manner and without challenging plant systems.

E.1 With all required monitors inoperable, no required automatic means of monitoring LEAKAGE are available, and immediate plant shutdown in accordance with LCO 3.0.3 is required.

SURVEILLANCE The Surveillances are modified by a Note to indicate that REQUIREMENTS when a channel is placed in an inoperable status solely for performance of required Surveillances, entry into associated Conditions and Required Actions may be delayed for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, provided the other required instrumentation (the drywell floor drain sump monitoring system or drywell continuous atmospheric monitoring channel, as applicable) is OPERABLE. Upon completion of the Surveillance, or expiration of the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> allowance, the channel must be returned to OPERABLE status or the applicable Condition entered and Required Actions taken. The 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> testing allowance is acceptable since it does not significantly reduce the probability of properly monitoring RCS leakage.

RCS Leakage Detection Instrumentation B 3.4.5 BASES SURVEILLANCE SR 3.4.5.1 REQUIREMENTS (continued) This SR is for the performance of a CHANNEL CHECK of the required drywell continuous atmospheric monitoring channels.

The check gives reasonable confidence that the channels are operating properly. The Frequency of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> is based on instrument reliability and is reasonable for detecting off normal conditions.

SR 3.4.5.2 This SR is for the performance of a CHANNEL FUNCTIONAL TEST of the required RCS leakage detection instrumentation. The test ensures that the monitors can perform their function in the desired manner. The test also verifies the alarm setpoint and relative accuracy of the instrument channel. A successful test of the required contact(s) of a channel relay may be performed by the verification of the change of state of a single contact of the relay. This clarifies what is an acceptable CHANNEL FUNCTIONAL TEST of a relay. This is acceptable because all of the other required contacts of the relay are verified by other Technical Specifications and non-Technical Specifications tests at least once per refueling interval with applicable extensions. The Frequency of 31 days considers instrument reliability, and operating experience has shown it proper for detecting degradation.

SR 3.4.5.3 This SR is for the performance of a CHANNEL CALIBRATION of required leakage detection instrumentation channels. The calibration verifies the accuracy of the instrument channel.

The Frequency is 92 days and operating experience has proven this Frequency is acceptable.

RHR Shutdown Cooling System-Cold Shutdown B 3.4.8 B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.8 Residual Heat Removal (RHR) Shutdown Cooling System-Cold Shutdown BASES BACKGROUND Irradiated fuel in the shutdown reactor core generates heat during the decay of fission products and increases the temperature of the reactor coolant. This decay heat must be removed to maintain the temperature of the reactor coolant

< 212°F in preparation for performing refueling operations, or the decay heat must be removed for maintaining the reactor in the Cold Shutdown condition.

The two redundant, manually controlled shutdown cooling subsystems (loops) of the RHR System provide decay heat removal. Each loop consists of two motor driven pumps, a heat exchanger, and associated piping and valves. Both loops have a common suction from the same reactor water recirculation loop. Each pump discharges the reactor coolant, after circulation through the respective heat exchanger, to the reactor via a reactor water recirculation loop. The RHR heat exchangers transfer heat to the RHR Service Water System.

APPLICABLE Decay heat removal by operation of the RHR System in the SAFETY ANALYSES shutdown cooling mode is not required for mitigation of any event or accident evaluated in the safety analyses (Ref. 1).

Decay heat removal is, however, an important safety function that must be accomplished or core damage could result. The RHR Shutdown Cooling System meets Criterion 4 of 10 CFR 50.36(c)(2)(ii) (Ref. 2).

LCO Two RHR shutdown cooling subsystems are required to be OPERABLE. An OPERABLE RHR shutdown cooling subsystem consists of one OPERABLE RHR pump, one heat exchanger, one or two RHR service water pumps providing water to the heat exchanger, as required for temperature control, and the associated piping and valves. The two subsystems have a common suction source and are allowed to have a common heat exchanger and common discharge piping. Thus, to meet the LCO, both RHR pumps (and two RHR service water pumps) in one (continued)

Since the piping and heat exchangers are passive components that are assumed not to fail, they are allowed to be common to both subsystems. In MODE 4, the RHR cross tie valves (1OMOV-20 and 1ORHR-09) may be opened to allow pumps in one loop to discharge through the opposite recirculation loop to make a complete subsystem. Additionally, each shutdown cooling subsystem is considered OPERABLE if it can be manually aligned (from the control room or locally) in the shutdown cooling mode for removal of decay heat. In MODE 4, one RHR shutdown cooling subsystem can provide the required cooling, but two subsystems are required to be OPERABLE to provide redundancy. Operation of one subsystem can maintain or reduce the reactor coolant temperature as required.

However, to ensure adequate core flow to allow for accurate average reactor coolant temperature monitoring, nearly continuous operation is required.

APPLICABILITY In MODE 4, the RHR System is required to be OPERABLE so that it may be operated in the shutdown cooling mode to remove decay heat to maintain coolant temperature below 212'F.

Otherwise, a recirculation pump is normally in operation to circulate coolant to provide for temperature monitoring.

In MODES 1 and 2, and in MODE 3 with reactor steam dome pressure greater than or equal to the RHR cut in permissive pressure, this LCO is not applicable. Operation of the RHR System in the shutdown cooling mode is not allowed above this pressure because the RCS pressure may exceed the design pressure of the shutdown cooling piping. Decay heat removal at reactor pressures greater than or equal to the RHR cut in permissive pressure is typically accomplished by condensing the steam in the main condenser. Additionally, in MODE 2 (continued)

JUSTIFICATION FOR DIFFERENCES FROM NUREG-1433, REVISION 1 ITS: 3.4.9 - RCS PRESSURE AND TEMPERATURE (P/T) LIMITS RETENTION OF EXISTING REQUIREMENT (CLB)

CLB1 JAFNPP has not developed the "Reactor Coolant System (RCS) PRESSURE AND TEMPERATURE LIMITS REPORT (PTLR)". References to limits in the PTLR are replaced with current requirements. In addition, consistent with current licensing basis (CTS 3.6.A.1), the reactor vessel and head flange minimum temperature is only required to be met when the reactor vessel head bolting studs are under tension. Therefore, SR 3.4.9.6, SR 3.4.9.7, and SR 3.4.9.8 have been modified to reflect this condition.

SR 3.4.9.4 requires the verification that the active recirculation loop flow exceeds 40% of rated drive flow or the active loop has been operating below 40% rated flow for a period no longer than 30 minutes.

(The Specification 3.5.1 word "required" has been added to ITS 3.5.1 Required Actions E.1 and F.1 for consistency with the usage NUREG ITS markup p 3.5-2 and throughout the ITS, since not all ADS valves are 3.5-5 required to be Operable: the unit "psig" has been added after the value "1040" in SR 3.5.1.8. since each value NUREG Bases markup p B 3.5 should have the unit immediately after it: the SR 11 3.5.1.4 Bases have been modified to include the information relocated by DOC LA4 (i.e., that the motor- Retyped ITS p 3.5-2 and 3.5 operated cross-tie valves be chain locked closed and the 5 manual cross-tie valve be locked closed): the words "low pressure" have been added to ITS 3.5.2 Condition C and Retyped ITS Bases p B 3.5-11 Required Actions A.1 and C.2 to be consistent with a similar addition to Condition A, since the Condition and Specification 3.5.2 Required Actions affect only the low pressure ECCS: the word "required" has been added to ITS 3.5.2 Required NUREG ITS markup p 3.5-7 Action C.2 for consistency with the usage throughout the ITS, since not all low pressure ECCS subsystems are NUREG Bases markup p B 3.5 required Operable; and the word "OPERABLE" has been 17 added to the ITS 3.5.2 Bases LCO section, consistent with a similar sentence in ITS 3.4.7 and ITS 3.4.8 Retyped ITS p 3.5-9 Bases.)

Retyped ITS Bases p B 3.5-20 Editorial The words "at the 258,000 gallon level" have been Specification 3.5.2 changed to "at approximately 258,000 gallons" in the SR 3.5.2.1 and SR 3.5.2.2 Bases. NUREG Bases markup p B 3.5 20 Retyped ITS Bases p B 3.5-24 Technical change DOC LA2 justified the relocation to the Bases the Specification 3.5.1 details in CTS 4.5.D.1.a that the simulated automatic actuation test for the ADS System opens the pilot DOC LA2 (DOCs p 11 of 24) valves. However, the NUREG and ITS Bases only states that the endpoint of the test is the solenoids, not the pilot valves. The LA DOC has been modified to clearly state that the endpoint is the solenoids and not the pilot valves. This is acceptable since SR 3.5.1.13, which is performed on a similar Frequency, actually opens the ADS valves, including the pilot valves.

DISCUSSION OF CHANGES ITS: 3.5.1 - ECCS - OPERATING TECHNICAL CHANGES - MORE RESTRICTIVE (continued)

M8 According to CTS 3.9.F.1, the reactor shall not be made critical unless both LPCI MOV Independent Power Supplies are operable which is effectively MODES 1 and 2. ITS 3.5.1 requires the low pressure core injection subsystems to be Operable in MODES 1, 2 and 3. Since the operability of the LPCI MOV Independent Power Supply effects the OPERABILITY of the associated LPCI subsystem, the operability requirements of LPCI MOV Independent Power Supplies have been extended to MODE 3. This ensures that each LPCI subsystem will remain operable with the required uninterruptable power supply during reactor conditions where there is significant core energy. This change is considered more restrictive and has no adverse effect on safety.

M9 CTS 4.6.E.4 requires the safety/relief valves to be manually opened every 24 months. ITS SR 3.5.1.13 requires this same manual opening but requires the actuation to be initiated on a Staggered Test Basis for each valve solenoid. This will ensure that a different solenoid will be used to actuate the valve every 24 months and is considered more restrictive since the current requirement does not specify which solenoid to use. This change is necessary to ensure both solenoids are tested within any 48 month period.

MIO CTS 3.5.A.5 requires all recirculation pump discharge valves to be Operable prior to reactor startup (or closed if permitted elsewhere in these specifications). ITS 3.5.1 and associated SR 3.5.1.6 also require all recirculation pump discharge valves to be Operable. However, if this requirement can not be met, then ITS SR 3.5.1.6 allows the I associated recirculation pump discharge valve to be "de-energized" in the closed position. Requiring the inoperable recirculation pump discharge valve to also be "de-energized" in the closed position represents an additional restriction on plant operation. This change is necessary to ensure the proper flow path for the associated LPCI subsystem.

M11 CTS 4.5.G.3 requires the HPCI System discharge piping to be vented from the high point of the system whenever HPCI is lined up to take suction from the condensate storage tank (CST) on a monthly basis. In ITS SR 3.5.1.1 this requirement must be met whenever HPCI is required to be Operable whether it is aligned to the CST or the suppression pool. This change is considered more restrictive on plant operation but necessary to help prevent a water hammer following an initiation signal.

M12 CTS 3.5.A.1 and 3.5.A.3 require the Core Spray (CS) and Low Pressure Coolant Injection (LPCI) Systems, respectively to be Operable whenever irradiated fuel is in the reactor vessel and prior to reactor startup from cold shutdown (this covers MODES 1, 2 in the ITS).

DISCUSSION OF CHANGES ITS: 3.5.1 - ECCS - OPERATING TECHNICAL CHANGES - LESS RESTRICTIVE (GENERIC)

LA4 CTS 3.5.A.3.b contains detailed descriptions of the requirements of assuring that the LPCI cross-tie line be isolated. ITS SR 3.5.1.4 requires that the cross tie valves be verified closed and electrical power be removed from the electrically powered motor operator.

Additional details on actual valve numbers and method of valve closing presents information that is not required for assuring that the cross tie be isolated. These additional details are proposed to be relocated to the Bases. As such, these details are not required to be in the ITS to provide adequate protection of the public health and safety. Changes to the Bases will be controlled by the provisions of the proposed Bases Control Program described in Chapter 5 of the Technical Specifications.

LA5 The requirement in CTS 4.6.E.3 concerning the integrity of the nitrogen system and components which provide manual and ADS actuation of the safety/relief valves are proposed to be relocated to the Technical Requirements Manual (TRM). The system will continue to be required to perform its required safety function to be considered OPERABLE. ITS SR 3.5.1.3 is added (refer to M6) to address the important characteristic of whether there is sufficient pneumatic pressure available to permit the actuation of the ADS valves should an accident occur. The Operability requirements of ITS 3.5.1 for ADS valves and the ITS definition of OPERABLE - OPERABILITY are adequate to ensure the ADS valves are maintained capable of performing their specified safety function. In addition, the surveillance being relocated will continue to be performed and will identify degradation of the ADS nitrogen system pressure retention capabilities. As such, this surveillance is not required to be in the ITS to provide adequate protection of the public health and safety. Changes to the relocated requirement in the TRM will be controlled by the provisions of 10 CFR 50.59.

LA6 CTS 4.5.G.1, 4.5.G.2, and CTS 4.5.G.3 present the technical detail of the method to be employed to assure that the Core Spray, Low Pressure Coolant Injection and High Pressure Coolant Injection pump discharge lines are full of water (shall be vented from the high point of the system and water flow observed). The detail pertaining to how these Surveillances are to be performed are proposed to be relocated to the Bases. These details are not necessary to ensure the Operability of the ECCS subsystems. The requirements of Specification 3.5.1, ECCS-Operating, and the associated SR 3.5.1.1 are adequate to ensure the ECCS subsystems remain Operable. Therefore, the relocated details are not required to be in the ITS to provide adequate protection of the public health and safety. Changes to the Bases will be controlled by the provisions of the Bases Control Program described in Chapter 5 of the Technical Specifications.

JAFNPP 3.5-6 Amendment (Rev. J)

ECCS - Operating B 3.5.1 BASES APPLICABLE b. Maximum cladding oxidation is g 0.17 times the total SAFETY ANALYSES cladding thickness before oxidation; (continued)

c. Maximum hydrogen generation from a zirconium water reaction is g 0.01 times the hypothetical amount that would be generated if all of the metal in the cladding surrounding the fuel, excluding the cladding surrounding the plenum volume, were to react;
d. The core is maintained in a coolable geometry; and
e. Adequate long term cooling capability is maintained.

The limiting single failures are discussed in Reference 5.

For a LOCA due to a large recirculation pump suction line pipe break, failure of the Division 2 125 VDC battery is considered the most severe failure. For a small break LOCA, HPCI failure is the most severe failure. In the analysis of events requiring ADS operation, it is assumed that only five of the seven ADS valves operate. Since six ADS valves are required to be OPERABLE, the explicit assumption of the failure of an ADS valve is not considered in the analysis.

The remaining OPERABLE ECCS subsystems provide the capability to adequately cool the core and prevent excessive fuel damage.

The ECCS satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii)

(Ref. 11).

LCO Each ECCS injection/spray subsystem and six ADS valves are required to be OPERABLE. The ECCS injection/spray subsystems are defined as the two CS subsystems, the two LPCI subsystems (which includes both pumps per subsystem),

and one HPCI System. The low pressure ECCS injection/spray subsystems are defined as the two CS subsystems and the two LPCI subsystems.

With less than the required number of ECCS subsystems OPERABLE, the potential exists that during a limiting design basis LOCA concurrent with the worst case single active component failure, the limits specified in Reference 10 could be exceeded. All ECCS subsystems must therefore be OPERABLE to satisfy the single failure criterion required by Reference 10.

JAFNPP B 3.5-5 Revision J

ECCS - Operating B 3.5.1 BASES ACTIONS B.1 and B.2 (continued)

If the inoperable low pressure ECCS subsystem(s) cannot be restored to OPERABLE status within the associated Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

C.1 and C.2 If the HPCI System is inoperable and the RCIC System is verified to be OPERABLE, the HPCI System must be restored to OPERABLE status within 14 days. In this condition, adequate core cooling is ensured by the OPERABILITY of the redundant and diverse low pressure ECCS injection/spray subsystems in conjunction with ADS. Also, the RCIC System will automatically provide makeup water at most reactor operating pressures. Verification of RCIC OPERABILITY immediately is therefore required when HPCI is inoperable. This may be performed as an administrative check by examining logs or other information to determine if RCIC is out of service for maintenance or other reasons. It does not mean to perform the Surveillances needed to demonstrate the OPERABILITY of the RCIC System. If the OPERABILITY of the RCIC System cannot be verified, however, Condition G must be immediately entered. If a single active component fails concurrent with a design basis LOCA, there is a potential, depending on the specific failure, that the minimum required ECCS equipment will not be available.

ECCS- Operating B 3.5.1 BASES ACTIONS D.1 and D.2 (continued)

In this condition, adequate core cooling is ensured by the OPERABILITY of the ADS and the remaining low pressure ECCS subsystems. However, the overall ECCS reliability is significantly reduced because a single active component failure in one of the remaining OPERABLE subsystems concurrent with a design basis LOCA may result in the ECCS not being able to perform its intended safety function.

Since both a high pressure system (HPCI) and low pressure subsystem are inoperable, a more restrictive Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is required to restore either the HPCI System or the low pressure ECCS injection/spray subsystem to OPERABLE status. This Completion Time is consistent with the recommendations provided in a reliability study cited in Reference 12 and has been found to be acceptable through operating experience.

E.1 The LCO requires six ADS valves to be OPERABLE in order to provide the ADS function. Reference 5 contains the results of an analysis that evaluated the effect of two of the seven ADS valves being out of service. This analysis shows that, assuming a failure of the HPCI System, operation of only five ADS valves will provide the required depressurization.

However, overall reliability of the ADS is reduced, because a single active component failure in the OPERABLE ADS valves could result in a reduction in depressurization capability.

Therefore, operation with five ADS valves is only allowed for a limited time. The 14 day Completion Time is consistent with the recommendations provided in a reliability study cited in Reference 12 and has been found to be acceptable through operating experience.

F.1 and F.2 If any one low pressure ECCS injection/spray subsystem or one LPCI pump in both LPCI subsystems is inoperable in addition to one required ADS valve inoperable, adequate core cooling is ensured by the OPERABILITY of HPCI and the remaining low pressure ECCS injection/spray subsystem(s).

However, overall ECCS reliability is reduced because a (continued)

JAFNPP B 3.5-8 Revision J

ECCS - Operating B 3.5.1 BASES ACTIONS F.1 and F.2 (continued) single active component failure concurrent with a design basis LOCA could result in the minimum required ECCS equipment not being available. Since both a high pressure system (ADS) and low pressure subsystem(s) are inoperable, a more restrictive Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is required to restore either the low pressure ECCS subsystem(s) or the ADS valve to OPERABLE status. This Completion Time is consistent with the recommendations provided in a reliability study cited in Reference 12 and has been found to be acceptable through operating experience.

G.1 and G.2 If any Required Action and associated Completion Time of Condition C, D, E, or F is not met, or if two or more required ADS valves are inoperable, the plant must be brought to a condition in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reactor steam dome pressure reduced to g 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

H.1 When multiple ECCS subsystems are inoperable, as stated in Condition H, the plant is in a condition outside of the accident analyses. Therefore, LCO 3.0.3 must be entered immediately.

SURVEILLANCE SR 3.5.1.1 REQUIREMENTS The flow path piping has the potential to develop voids and pockets of entrained air. Maintaining the pump discharge lines of the HPCI System, CS System, and LPCI subsystems full of water ensures that the ECCS will perform properly, injecting its full capacity into the RCS upon demand. This will also prevent a water hammer following an ECCS (continued)

JAFNPP B 3.5-9 Revision J

ECCS - Operating B 3.5.1 BASES SURVEILLANCE SR 3.5.1.2 (continued)

REQUIREMENTS includes when the system is being realigned from or to the RHR shutdown cooling mode. At the low pressures and decay heat loads associated with operation in MODE 3 with reactor steam dome pressure less than the shutdown cooling permissive pressure, a reduced complement of low pressure ECCS subsystems should provide the required cooling, thereby allowing operation of RHR shutdown cooling, when necessary.

SR 3.5.1.3 Verification every 31 days that ADS pneumatic supply header pressure is Ž 95 psig ensures adequate pneumatic pressure for reliable ADS operation. The accumu ator on each ADS valve provides pneumatic pressure for valve actuation. The design pneumatic supply pressure requirements for the accumulator are such that, following a failure of the pneumatic supply to the accumulator, at least one valve actuation can occur with the drywell at 70% of design pressure (Ref. 13). The ECCS safety analysis assumes only one actuation to achieve the depressurization required for operation of the low pressure ECCS. This minimum required pressure of ; 95 psig is provided by the ADS nitrogen supply. The 31 day Frequency takes into consideration administrative controls over operation of the pneumatic system and alarms for low pneumatic pressure.

SR 3.5.1.4 Verification every 31 days that the RHR System cross tie valves are closed and power to the motor operated valve is disconnected ensures that each LPCI subsystem remains independent and a failure of the flow path in one subsystem will not affect the flow path of the other LPCI subsystem.

Acceptable methods of removing power to the operator include de-energizing breaker control power or racking out or removing the breaker. If one or more of the RHR System cross tie valves are open or power has not been removed from the motor operated valve, both LPCI subsystems must be considered inoperable. In addition, plant procedures require the motor operated cross tie valve to be chain locked closed and the manual cross tie valve to be locked closed. The 31 day Frequency has been found acceptable, I

REQUIREMENTS considering that these valves are under strict administrative controls that will ensure the valves continue to remain closed with either control or motive power removed.

SR 3.5.1.5 Cycling open and closed each LPCI motor operated valve independent power supply battery charger AC input breaker and verification that each LPCI inverter output has a voltage of 2 576 V and g 624 V while supplying its respective bus demonstrates the capability of the supply to become independent from emergency AC power and that the AC electrical power is available to ensure proper operation of the associated LPCI injection and heat exchanger bypass valves and the recirculation pump discharge valve. Each inverter and battery charger AC input breaker must be OPERABLE for the associated LPCI subsystem to be OPERABLE.

The 31 day Frequency has been found acceptable based on operating experience.

SR 3.5.1.6 Cycling the recirculation pump discharge valves through one complete cycle of full travel demonstrates that the valves are mechanically OPERABLE and will close when required.

Upon initiation of an automatic LPCI subsystem injection signal, these valves are required to close to ensure full LPCI subsystem flow injection in the reactor via the recirculation jet pumps. De-energizing the valve in the closed position will also ensure the proper flow path for the LPCI subsystem. Acceptable methods of de-energizing the valve include de-energizing breaker control power, racking out the breaker or removing the breaker.

The specified Frequency is once during reactor startup before THERMAL POWER is > 25% RTP. However, this SR is modified by a Note that states the Surveillance is only required to be performed if the last performance was more than 31 days ago. Verification during reactor startup prior to reaching > 25% RTP is an exception to the normal Inservice Testing Program generic valve cycling Frequency of (continued)

REQUIREMENTS 92 days, but is considered acceptable due to the demonstrated reliability of these valves. If the valve is inoperable and in the open position, the associated LPCI subsystem must be declared inoperable.

SR 3.5.1.7, SR 3.5.1.8, and SR 3.5.1.9 The performance requirements of the low pressure ECCS pumps are determined through application of the 10 CFR 50, Appendix K criteria (Ref. 8). This periodic Surveillance is performed (in accordance with the ASME Code,Section XI, requirements for the ECCS pumps) to verify that the ECCS pumps will develop at least the flow rates required by the respective analyses. The low pressure ECCS pump flow rates ensure that adequate core cooling is provided to satisfy the acceptance criteria of Reference 10. The pump flow rates are verified against a system head equivalent to the RPV pressure expected during a LOCA. The total system pump outlet pressure is adequate to overcome the elevation head pressure between the pump suction and the vessel discharge, the piping friction losses, and RPV pressure present during a LOCA. These values may be established during preoperational testing.

The flow tests for the HPCI System are performed at two different pressure ranges such that system capability to provide rated flow against a system head corresponding to reactor pressure is tested at both the higher and lower operating ranges of the system. The required system head should overcome the RPV pressure and associated discharge line losses. Adequate reactor steam pressure must be available to perform these tests. Additionally, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the HPCI System diverts steam flow.

Therefore, sufficient time is allowed after adequate pressure and flow are achieved to perform these tests.

Adequate reactor steam pressure must be 2 970 psig to perform SR 3.5.1.8 and > 150 psig to perform SR 3.5.1.9.

Adequate steam flow is represented by at least one turbine bypass valve open or main turbine generator load is greater than 100 MWe. Reactor startup is allowed prior to performing the low pressure Surveillance test because the reactor pressure is low and the time allowed to satisfactorily perform the Surveillance test is short. The (continued)

JAFNPP B 3.5-13 Revision J

ECCS- Operating B 3.5.1 BASES SURVEILLANCE SR 3.5.1.7, SR 3.5.1.8, and SR 3.5.1.9 (continued)

REQUIREMENTS reactor pressure is allowed to be increased to normal operating pressure since it is assumed that the low pressure test has been satisfactorily completed and there is no indication or reason to believe that HPCI is inoperable.

Therefore, SR 3.5.1.8 and SR 3.5.1.9 are modified by Notes that state the Surveillances are not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the reactor steam pressure and flow are adequate to perform the test. The 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allowed for performing the flow test after the required pressure and flow are reached is sufficient to achieve stable conditions for testing and provides reasonable time to complete the SRs.

The Frequency for SR 3.5.1.7 and SR 3.5.1.8 is in accordance with the Inservice Testing Program requirements. The 24 month Frequency for SR 3.5.1.9 is based on the need to perform the Surveillance under the conditions that apply during a startup from a plant outage. Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based on the refueling cycle. Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.

SR 3.5.1.10 The ECCS subsystems are required to actuate automatically to perform their design functions. This Surveillance verifies that, with a required system initiation signal (actual or simulated), the automatic initiation logic of HPCI, CS, and LPCI will cause the systems or subsystems to operate as designed, including actuation of the system throughout its emergency operating sequence, automatic pump startup and actuation of all automatic valves to their required positions. The HPCI System actual or simulated automatic actuation test must be performed with adequate steam pressure for verification of automatic pump startup.

Additionally, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the HPCI System diverts steam flow. Thus, sufficient time is allowed after adequate pressure and flow are achieved to perform this test associated with the HPCI System. Adequate reactor steam dome pressure is > 150 psig. Adequate steam flow is represented by at least one turbine bypass valve open. This SR also ensures that the HPCI System will automatically (continued)

ECCS - Operating B 3.5.1 BASES SURVEILLANCE SR 3.5.1.10 (continued)

REQUIREMENTS restart on an RPV low water level (Level 2) signal received subsequent to an RPV high water level (Level 8) trip. In addition, this SR also ensures that the HPCI suction is automatically transferred from the CSTs to the suppression pool on high suppression pool water level or low CST water level. The LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1 overlaps this Surveillance to provide complete testing of the assumed safety function.

For CS and LPCI, the 24 month Frequency is based on the need to perform the Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the reactor at power. For HPCI, the 24 month Frequency is based on the need to perform the surveillance under conditions that apply during a startup from a plant outage. Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based on the refueling cycle. Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.

This SR is modified by two Notes. Note 1 states that for the HPCI System, the Surveillance is not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the reactor steam pressure and flow are adequate to perform the test. The 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allowed for performing the actual or simulated automatic actuation for the HPCI System after the required pressure and flow are reached is sufficient to achieve stable conditions for testing and provides reasonable time to complete the SR. Note 2 excludes vessel injection/spray during the Surveillance. Since all active components are testable and full flow can be demonstrated by recirculation through the test line, coolant injection into the RPV is not required during the Surveillance.

SR 3.5.1.11 The ADS designated S/RVs are required to actuate automatically upon receipt of specific initiation signals.

A system functional test is performed to demonstrate that the mechanical portions of the ADS function (i.e.,

solenoids) operate as designed when initiated either by an actual or simulated initiation signal, causing proper actuation of all the required components. SR 3.5.1.13 and the LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1 (continued)

JAFNPP B 3.5-15 Revision J

ECCS - Operating B 3.5.1 BASES SURVEILLANCE SR 3.5.1.11 (continued)

REQUIREMENTS overlap this Surveillance to provide complete testing of the assumed safety function. The 24 month Frequency is based on the need to perform the Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the reactor at power. Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based on the refueling cycle.

Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.

This SR is modified by a Note that excludes valve actuation since the valves are individually tested in accordance with SR 3.5.1.13. This prevents the possibility of an RPV pressure blowdown.

SR 3.5.1.12 A LPCI motor operated valve independent power supply subsystem inverter test is a test of the inverter's capability, as found, to satisfy the design requirements (inverter duty cycle). The discharge rate and test length correspond to the design duty cycle requirements.

The Frequency of 24 months is acceptable, given plant conditions required to perform the test and the other requirements existing to ensure adequate LPCI inverter performance during the 24 month interval. In addition, the Frequency is intended to be consistent with expected fuel cycle lengths.

SR 3.5.1.13 A manual actuation of each required ADS valve is performed while bypassing main steam flow to the condenser and observing Ž 10% closure of the turbine bypass valves to verify that the valve and solenoid are functioning properly and that no blockage exists in the S/RV discharge lines.

This can also be demonstrated by the response of the turbine control or bypass valve or by a change in the measured flow or by any other method suitable to verify steam flow.

REQUIREMENTS Adequate reactor steam dome pressure must be available to perform this test to avoid damaging the valve. Also, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the ADS valves divert steam flow upon opening.

Sufficient time is therefore allowed after the required pressure and flow are achieved to perform this SR. Adequate pressure at which this SR is to be performed is Ž 970 psig (the pressure consistent with vendor recommendations).

Adequate steam flow is represented by at least two pr more turbine bypass valves open or total steam flow Ž 10 lb/hr.

These conditions will require the plant to be in MODE 1, which has been shown to be an acceptable condition to perform this test. This test causes a small neutron flux transient which may cause a scram in MODE 2 while operating close to the Average Power Range Monitors Neutron Flux-High (Startup) Allowable Value. Reactor startup is allowed prior to performing this SR because valve OPERABILITY and the setpoints for overpressure protection are verified, per ASME requirements, prior to valve installation. Therefore, this SR is modified by a Note that states the Surveillance is not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure and flow are adequate to perform the test. The 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allowed for manual actuation after the required pressure and flow are reached is sufficient to achieve stable conditions and provides adequate time to complete the Surveillance. SR 3.5.1.11 and the LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.1 overlap this Surveillance to provide complete testing of the assumed safety function.

The Frequency of 24 months on a STAGGERED TEST BASIS ensures that both solenoids for each ADS valve are alternately tested. The Frequency is based on the need to perform the Surveillance under the conditions that apply during a startup from a plant outage. Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based on the refueling cycle. Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.

APPLICABLE The ECCS performance is evaluated for the entire spectrum of SAFETY ANALYSES break sizes for a postulated loss of coolant accident (LOCA). The long term cooling analysis following a design basis LOCA (Ref. 1) demonstrates that only one low pressure ECCS injection/spray subsystem is required, post LOCA, to maintain adequate reactor vessel water level in the event of an inadvertent vessel draindown. It is reasonable to assume, based on engineering judgement, that while in MODES 4 and 5, one low pressure ECCS injection/spray subsystem can maintain adequate reactor vessel water level. To provide redundancy, a minimum of two low pressure ECCS injection/spray subsystems are required to be OPERABLE in MODES 4 and 5.

APPLICABLE The ECCS performance is evaluated for the entire spectrum of SAFETY ANALYSES break sizes for a postulated loss of coolant accident (LOCA). The long term cooling analysis following a design basis LOCA (Ref. 1) demonstrates that only one low pressure ECCS injection/spray subsystem is required, post LOCA, to maintain adequate reactor vessel water level in the event of an inadvertent vessel draindown. It is reasonable to assume, based on engineering judgement, that while in MODES 4 and 5, one low pressure ECCS injection/spray subsystem can maintain adequate reactor vessel water level. To provide redundancy, a minimum of two low pressure ECCS injection/spray subsystems are required to be OPERABLE in MODES 4 and 5.

The low pressure ECCS subsystems satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii) (Ref. 2).

LCO Two low pressure ECCS injection/spray subsystems are required to be OPERABLE. The low pressure ECCS injection/

spray subsystems consist of two CS subsystems and two LPCI subsystems. Each CS subsystem consists of one motor driven pump, piping, and valves to transfer water from the suppression pool or from both condensate storage tanks (CSTs) to the reactor pressure vessel (RPV). The CST suction source consists of two CSTs connected in parallel.

Each OPERABLE LPCI subsystem consists of one motor driven pump, piping, and valves to transfer water from the suppression pool to the RPV. Only a single LPCI pump is required per subsystem because of the larger injection capacity in relation to a CS subsystem. In MODES 4 and 5, the RHR System cross tie valves are not required to be closed.

REQUIREMENTS equivalent to 324 inches (27 ft), ensures that the CS System can supply at least 50,000 gallons of makeup water to the RPV. An excess amount of water remains as a supplementary volume and to ensure adequate CS pump NPSH. The CS suction is uncovered at approximately 258,000 gallons (two tanks).

However, as noted, only one required CS subsystem may take credit for the CST option during OPDRVs. During OPDRVs, the volume in the CSTs may not provide adequate makeup if the RPV were completely drained. Therefore, only one CS subsystem is allowed to use the CSTs. This ensures the other required ECCS subsystem has adequate makeup volume.

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM ADMINISTRATIVE CHANGES Al In the conversion of the James A. FitzPatrick Nuclear Power Plant (JAFNPP) Current Technical Specification (CTS) to the proposed plant specific Improved Technical Specifications (ITS) certain wording preferences or conventions are adopted which do not result in technical changes. Editorial changes, reformatting, and revised numbering are adopted to make the ITS consistent with the conventions in NUREG-1433, "Standard Technical Specifications, General Electric Plants, BWR/4,"

Revision 1 (i.e., Improved Standard Technical Specifications (ISTS)).

A2 CTS 3.5.G.1 requires the RCIC pump to be considered inoperable when the associated pump discharge piping cannot be maintained in a filled condition. This will require entry into CTS 3.5.E where 7 days (LI) is allowed to restore the RCIC System to Operable status. In the ITS, the requirement that the RCIC discharge piping must be filled is reflected in SR 3.5.3.1. Therefore, since this SR is directly related to the operability requirements of the RCIC System, this cross reference can be deleted and this change considered administrative. This change is consistent with NUREG-1433, Revision 1.

A3 CTS 4.5.E.L.a (ITS SR 3.5.3.5) is modified by Note 2 that excludes vessel injection during the Surveillance. The Bases indicates that this test must include actuation of all automatic valves to their required positions. Since all active components are testable and full flow can be demonstrated by recirculation through the test line, coolant injection into the RPV is not required during the Surveillance. This Note, therefore, is explicit recognition that ITS SR 3.5.3.5 can be 1L satisfied by a series of overlapping tests. Since surveillance testing of RCIC (CTS 4.5.E.1.a) does not presently require actual injection, and is currently satisfied by a series of overlapping tests, the addition of the Note excluding vessel injection is an administrative change.

A4 Not used.

A5 CTS 3.5.E.3 does not require the Reactor Core Isolation Cooling (RCIC)

System to be Operable during low power physics testing and during reactor operator training provided the reactor coolant temperature is 0

  • 212°F. Therefore, since there are no Operability requirements for the RCIC System during the conditions of CTS 3.5.E.3, the allowances provided are meaningless and therefore this deletion is considered administrative. This change is consistent with NUREG-1433, Revision 1.

JAFNPP Page 1 of 7 Revision J

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM TECHNICAL CHANGES - MORE RESTRICTIVE M1 CTS 3.5.E.2 requires the reactor to be placed in the cold condition and pressure less than 150 psig within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when CTS 3.5.E cannot be met. This requirement is proposed to be replaced by ITS 3.5.3 Required Actions B.1 and B.2 which require the plant be in MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to reduce reactor steam dome pressure to : 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> (see L2) under the same condition. Based on operating experience, this Completion Time limit still allows for an orderly transition to MODE 3 without challenging plant systems. This change is more restrictive because it provides an additional requirement to place the plant in MODE 3 in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> prior to requiring reactor steam dome pressure to be S150 psig.

M2 CTS 4.5.E.1 requirement, to permit up to 10 days of continuous operation from the time steam becomes available until RCIC Surveillances need to be performed, is being changed. The Note to ITS SR 3.5.3.3 and SR 3.5.3.4 and Note 1 of SR 3.5.3.5 allow only 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> from the time reactor steam pressure and flow are adequate to perform the test. The 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> allows sufficient time to achieve stable conditions for testing and provides a reasonable time to complete the SR without impacting plant operation. Reducing the allowable time to perform the test, from 10 days to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, imposes additional operational limitations. This change will require that the actual surveillances be performed sooner in the plant startup, and thereby demonstrate RCIC Operability sooner than current requirements dictate. Therefore, this change is considered more restrictive but necessary to ensure Operability within a reasonable time period when the equipment is required to be Operable.

M3 The CTS 4.5.E.l.d requirement, that RCIC deliver at least 400 gpm against a system head corresponding to a reactor vessel pressure of 1,195 psig to 150 psig, is being divided into two separate Surveillance Requirements SR 3.5.3.3 and SR 3.5.3.4. ITS SR 3.5.3.3, will require demonstration of the RCIC pump capability at the high reactor vessel pressure each 92 days, with reactor pressure Ž 970 psig and

  • 1040 psig.

Reactor pressures of ! 970 psig and

  • 1040 psig represents a nominal value at rated conditions within the CTS required band for testing.

This pressure range represents conditions of lower driving pressure for the RCIC turbine and thus, a more restrictive condition under which to provide the required flow. ITS SR 3.5.3.4 will require demonstration of the RCIC pump capability at the low reactor vessel pressure every 24 months with reactor pressure g 165 psig. Reactor pressure of

  • 165 psig is near the lower limit (i.e., > 150 psig) of operability/capability of the RCIC turbine, yet provides a 15 psig range above the lower limit in which to conduct the test. CTS required that the RCIC test confirm the capability of the pump at 150 psig. As a practical consideration, the test is performed when sufficient pressure is available at near 150 psig. To require the test at
  • 150 psig would be to require a test JAFNPP Page 2 of 7 Revision J

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM TECHNICAL CHANGES - MORE RESTRICTIVE M3 (continued) of the capability of the pump outside the required operability range.

This change will ensure the RCIC System is tested at both the high and low pressures at the proposed Frequencies and is therefore considered more restrictive on plant operation but necessary to ensure RCIC remains Operable over its full operating range.

M4 CTS 4.5.G.3 requires the RCIC System discharge piping to be vented from the high point of the system whenever RCIC is lined up to take suction from the condensate storage tank (CST). In ITS SR 3.5.3.1, this requirement must be met whenever RCIC is required to be Operable, not just when RCIC is lined up to take suction from the CST. This change is considered more restrictive on plant operation but necessary to help prevent a water hammer following an initiation signal.

TECHNICAL CHANGES - LESS RESTRICTIVE (GENERIC)

LA1 The details of CTS 4.5.E.1.a footnote *, that states "automatic restart on a low water level signal which is subsequent to a high water level signal", are proposed to be relocated to the Bases. The Bases for SR 3.5.3.5 states in part that "this test also ensures the RCIC System will automatically restart on an RPV low water level (Level 2) signal received subsequent to an RPV high water level (Level 8) trip." The requirement in ITS SR 3.5.3.5 is adequate to ensure the RCIC automatic actuation capability is verified to ensure Operability. As such, these details are not required to be in the ITS to provide adequate protection of the public health and safety. Changes to the Bases will be controlled by the provisions of the proposed Bases Control Program described in Chapter 5 of the Technical Specifications.

LA2 The details in CTS 4.5.G.3 which describe the method to be employed to assure that the RCIC discharge piping is full of water (shall be vented from the high point of the system and water flow observed) are proposed to be relocated to the Bases. These details are not necessary to ensure the Operability of the RCIC System. The requirements of LCO 3.5.3 (RCIC System) that the RCIC System must be Operable and the associated Surveillances are adequate to ensure the RCIC System remains Operable.

Therefore, the relocated details are not required to be in the ITS to JAFNPP Page 3 of 7 Revision J

CTS 4.5.E.1.c requires the RCIC motor operated valves to be tested for Operability every 92 days. These requirements are proposed to be relocated to the TRM. These details are not necessary to ensure Operability of the RCIC System. The requirements of LCO 3.5.3 that the RCIC System must be OPERABLE and SRs 3.5.3.3, 3.5.3.4, and 3.5.3.5 are adequate to ensure the RCIC System remains Operable. Therefore, the relocated requirements are not required to be in the ITS to provide adequate protection of the public health and safety. The TRM will be incorporated by reference in to the JAFNPP UFSAR at ITS Implementation.

Changes to the relocated requirements in the TRM will be controlled by the provisions of 10 CFR 50.59.

TECHNICAL CHANGES - LESS RESTRICTIVE (SPECIFIC)

Li CTS 3.5.E.1 allows continued operation for a maximum of 7 days after RCIC is determined to be inoperable. ITS 3.5.3 Required Action A.2 allows continued operation for a maximum of 14 days under the same conditions. As in the existing Specification, the 14 day Completion Time for restoring RCIC is contingent upon the Operability of HPCI. The 14 day completion time is based on a reliability study that evaluated the impact on ECCS availability (Memorandum from R.L. Baer (NRC) to V.

Stello, JR. (NRC), "Recommended Interim Revisions to LCOs for ECCS Components," December 1, 1975). The main factor contributing to the acceptability of allowing continued operation for 14 days with RCIC inoperable is the similar functions of HPCI and RCIC, and that the HPCI is capable of performing the RCIC function, at a substantially higher capacity.

L2 CTS 3.5.E.2 requires the reactor be in the cold condition and reactor pressure be reduced to less than 150 psig within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when CTS 3.5.E cannot be met. ITS 3.5.3 Required Actions B.1 and B.2 requires the plant to be in MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (Ml) and to reduce reactor steam dome pressure to . 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> under the same conditions.

This change is less restrictive since the time to reduce pressure has JAFNPP Page 4 of 7 Revision J

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM TECHNICAL CHANGES - LESS RESTRICTIVE (SPECIFIC)

L2 (continued) been extend from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. This change is acceptable since the compensatory action added in accordance with M1 and this extended time to be

  • 150 psig will ensure a more continuous reduction in power and reactor coolant pressure within the specified maximum cooldown rate and within the capabilities of the plant. The additional time to complete these ACTIONS reduces the potential for a plant event that could challenge plant safety systems.

L3 CTS 4.5.E.1.a stipulates a simulated automatic actuation test shall be performed. The phrase "actual or," in reference to the automatic initiation signal, has been added to CTS 4.5.E.1.a (ITS SR 3.5.3.5) for verifying that each RCIC subsystem actuates on an automatic initiation signal. This allows satisfactory automatic system initiations to be used to fulfill the Surveillance Requirements. Operability is adequately demonstrated in either case since the RCIC System itself can not discriminate between "actual" or "simulated" signals.

L4 CTS 4.5.E.2 requires the verification that the HPCI System is Operable immediately and daily thereafter when RCIC is determined to be inoperable. ITS 3.5.3 Required Action A.1 requires immediate verification by administrative means that the HPIC System is Operable, but the explicit requirement for periodic continuing verification has been deleted. These verifications are an implicit part of using Technical Specifications and determining the appropriate Conditions to enter and Actions to take in the event of inoperability of Technical Specification equipment. In addition, plant and equipment status is continuously monitored by control room personnel. The results of this monitoring process are documented in records/logs maintained by control room personnel. The continuous monitoring process includes re evaluating the status of compliance with Technical Specification requirements when Technical Specification equipment becomes inoperable using the control room records/logs as aids. Therefore, the explicit requirement to periodically verify the Operability of HPCI when RCIC is inoperable is considered to be unnecessary for ensuring compliance with the applicable Technical Specification actions.

L5 CTS 3.5.E.2 requires reactor pressure to be reduced to less than 150 psig. ITS 3.5.3 Required Action B.2 will require reactor pressure be reduced to : 150 psig. This change is slightly less restrictive since a reduction in reactor steam dome pressure to only 150 psig will be considered as satisfying the requirement, whereas in the CTS reactor steam dome pressure must be reduced to < 150 psig. This change is JAFNPP Page 5 of 7 Revision J

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM TECHNICAL CHANGES - LESS RESTRICTIVE (SPECIFIC)

L5 (continued) acceptable since it places the plant outside of the current and proposed Applicability of the RCIC System in CTS 3.5.E.1 (ITS 3.5.3 Applicability). This change is consistent with NUREG-1433, Revision 1.

L6 The CTS 4.5.E.1.d specification that required RCIC flow be demonstrated "against a system head corresponding to a reactor vessel pressure of 1195 to 150 psig" is changed to a demonstration of required RCIC flow "against a system head corresponding to reactor pressure", consistent with NUREG-1433, Revision 1 requirements. The CTS 4.5.E.1.d specification is represented in ITS as two surveillances (see DOC M3),

ITS SR 3.5.3.4 performed at a reactor pressure of < 165 psig, and ITS SR 3.5.3.3 performed with reactor pressure 2 970 and . 1040 psig.

Adopting NUREG wording for ITS SR 3.5.3.4 results in testing requirements analogous to the CTS specification and current testing practice at the low pressure end of the HPCI operability band. Adopting NUREG wording for ITS SR 3.5.3.3 constitutes a less restrictive change.

The RCIC system is designed to provide its rated flow over a reactor pressure range of 150 psig to a maximum pressure based on the lowest SRV safety setpoint. The CTS range of 1195 to 150 psig corresponds to the entire range of operability for RCIC and is intended to demonstrate RCIC operability throughout this range. As noted in DOC M3, however, the CTS does not specify a reactor pressure range for test performance.

In practice, the test is performed at the low end of the range (i.e.,

-150 psig) after start-up, and within the normal reactor operating pressure range (970 to 1040 psig) on a periodic basis. CTS testing at the low end of the range demonstrates flow against a discharge head based upon a differential above reactor pressure, consistent with the proposed ITS SR 3.5.3.4. CTS testing in the normal reactor operating pressure range, however, demonstrates flow against a system head derived from the "reactor vessel pressure of 1195" CTS value, not "against a system head corresponding to reactor pressure" as proposed by ITS SR 3.5.3.3.

In actual operation, RCIC system inlet steam pressure and RCIC pump discharge pressure correspond to reactor pressure with allowance for line losses. Requiring that RCIC demonstrate minimum system design flow "against a system head corresponding to a reactor vessel pressure of 1195" with actual reactor steam dome pressure in the normal operating range is overly conservative, since the condition represents less driving steam pressure for the RCIC turbine than would be available if a discharge pressure corresponding to 1195 psig reactor pressure were actually required. RCIC is required to exceed its design operating JAFNPP Page 6 of 7 Revision J

DISCUSSION OF CHANGES ITS: 3.5.3 - RCIC SYSTEM TECHNICAL CHANGES - LESS RESTRICTIVE (SPECIFIC)

L6 (continued) requirements to satisfy such test conditions. The NUREG-1433, Revision 1 requirement specifying a reactor pressure range for performing the test and requiring demonstration of flow rate "against a system head corresponding to reactor pressure" constitutes a more accurate and appropriate demonstration of RCIC operability than the CTS in that the NUREG requirements more accurately reflect actual RCIC operating conditions. Since adoption of the NUREG requirements for ITS SR 3.5.3.3 removes a degree of overly restrictive conservatism, the change is considered less restrictive.

RCIC System B 3.5.3 CORE ISOLATION B 3.5 EMERGENCY CORE COOLING SYSTEMS (ECCS) AND REACTOR COOLING (RCIC) SYSTEM B 3.5.3 RCIC System BASES RCIC BACKGROUND The RCIC System is not part of the ECCS; however, the System is included with the ECCS section because of their similar functions.

The RCIC System is designed to operate either automatically or manually following reactor pressure vessel (RPV) isolation accompanied by a loss of coolant flow from the feedwater system to provide adequate core cooling and

DB4 JAFNPP was designed and under construction prior to the promulgation of Appendix A to 10 CFR 50 - General Design Criteria for Nuclear Power Plant. The JAFNPP Construction Permit was issued on May 20, 1970. The proposed General Design Criteria (GDC) were published in the Federal Register on July 11, 1967 (32 FR 10213) and became effective on February 20, 1971 (32 DR 3256). UFSAR Section 16.6 - Conformance to AEC Design Criteria, describes the JAFNPP current licensing basis with regard to the GDC.

The selected pressure condition of < 165 psig in SR 3.5.3.4 is very close to the lower range where RCIC is required to be Operable, however, at the same time allows some flexibility to establish the condition. The Bases has been modified as required to reflect these changes to the Specification.

RCIC System B 3.5.3 BASES (continued)

ACTIONS A.1 and A.2 If the RCIC System is inoperable during MODE 1, or MODE 2 or 3 with reactor steam dome pressure > 150 psig, and the HPCI System is verified to be OPERABLE, the RCIC System must be restored to OPERABLE status within 14 days. In this Condition, loss of the RCIC System will not affect the overall plant capability to provide makeup inventory at high reactor pressure since the HPCI System is the only high pressure system assumed to function during a loss of coolant accident (LOCA). OPERABILITY of HPCI is therefore verified immediately when the RCIC System is inoperable. This may be performed as an administrative check, by examining logs or other information, to determine if HPCI is out of service for maintenance or other reasons. It does not mean it is necessary to perform the Surveillances needed to demonstrate the OPERABILITY of the HPCI System. If the OPERABILITY of the HPCI System cannot be verified, however, Condition B must be immediately entered. For transients and certain abnormal events with no LOCA, RCIC (as opposed to HPCI) is the preferred source of makeup coolant because of its relatively small capacity, which allows easier control of the RPV water level. Therefore, a limited time is allowed to restore the inoperable RCIC to OPERABLE status.

The 14 day Completion Time is consistent with the recommendations in a reliability study (Ref. 4) that evaluated the impact on ECCS availability, assuming various components and subsystems were taken out of service. The results were used to calculate the average availability of ECCS equipment needed to mitigate the consequences of a LOCA as a function of allowed outage times (AOTs). Because of similar functions of HPCI and RCIC, the AOTs (i.e.,

Completion Times) determined for HPCI are also applied to RCIC.

B.1 and B.2 If the RCIC System cannot be restored to OPERABLE status within the associated Completion Time, or if the HPCI System is simultaneously inoperable, the plant must be brought to a condition in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reactor steam dome pressure reduced to g 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

REQUIREMENTS 31 days is further justified because the valves are operated under procedural control and because improper valve position would affect only the RCIC System. This Frequency has been shown to be acceptable through operating experience.

SR 3.5.3.3 and SR 3.5.3.4 IfN The RCIC pump flow rates ensure that the system can maintain reactor coolant inventory during pressurized conditions with the RPV isolated. The flow tests for the RCIC System are performed at two different pressure ranges such that system capability to provide rated flow against a system head corresponding to reactor pressure is tested both at the higher and lower operating ranges of the system. The required system head should overcome the RPV pressure and associated discharge line losses. Adequate reactor steam pressure must be available to perform these tests.

Additionally, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the RCIC System diverts steam flow. Therefore, sufficient time is allowed after adequate pressure and flow are achieved to perform these SRs.

Adequate reactor steam pressure must be 2 970 psig to perform SR 3.5.3.3 and > 150 psig to perform SR 3.5.3.4.

Adequate steam flow is represented by at least one turbine bypass valve open, or main turbine generator load is greater than 100 MWe. Reactor startup is allowed prior to performing the low pressure Surveillance because the reactor pressure is low and the time allowed to satisfactorily perform the Surveillance is short. The reactor pressure is allowed to be increased to normal operating pressure since it is assumed that the low pressure Surveillance has been satisfactorily completed and there is no indication or reason to believe that RCIC is inoperable.

These SRs are modified by Notes that state the Surveillances are not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the reactor steam pressure and flow are adequate to perform the test.

A 92 day Frequency for SR 3.5.3.3 is consistent with the Inservice Testing Program requirements. The 24 month Frequency for SR 3.5.3.4 is based on the need to perform the Surveillance under conditions that apply during a startup from a plant outage. Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based on the refueling cycle.

Therefore, the Frequency was concluded to be acceptable from a reliability standpoint.

This Surveillance verifies that, with a required system initiation signal (actual or simulated), the automatic initiation logic of the RCIC System will cause the system to operate as designed, including actuation of the system throughout its emergency operating sequence; that is, automatic pump startup and actuation of all automatic valves to their required positions. This test also ensures the RCIC System will automatically restart on an RPV low water level (Level 2) signal received subsequent to an RPV high water level (Level 8) signal (Level 8 signal closes RCIC steam inlet valve, and subsequent Level 2 signal will re open valve) and that the suction is automatically transferred from the CST to the suppression pool. The LOGIC SYSTEM FUNCTIONAL TEST performed in LCO 3.3.5.2 overlaps this Surveillance to provide complete testing of the assumed design function.
