REACTIVITY CONTROL SYSTEMS BASES MODERATOR TEMPERATURE COEFFICIENT (Cont'inued)
The most negative MTC value equivalent te the most positive moderator density coefficient (MDC), was obtained by incrementally correcting the MDC used in the FSAR analyses to nominal operating conditions. These corrections involved subtracting the incremental change.in the MDC associated with a core condition of all rods inserted (most positive MDC) to an all rods withdrawn condition and, a conversion for the rate of change of moderator density with temperature at RATED THERMAL POWER conditions. This value of the MDC was then transformed into the limiting MTC End of Life (E0L) value specified in the CORE OPERATING LIMITS REPORT (COLR). The 300 ppm surveillance limit MTC value specified in the COLR represents a conservative value (with corrections for-burnup and soluble boron) at a core condition of 300 ppm equilibrium baron concentration and is obtained by making these corrections to the limiting E0L MTC value specified in the COLR.
The Surveillance Requirements for measurement of the MTC at the beginning and near the end of the fuel cycle are adequate to confirm that the MTC remains within its limits since this coefficient changes slowly due principally to the reduction in RCS boron concentration associated with fuel burnup.
3/4.1.1.4 MINIMUM TEMPERATURE FOR CRITICALITY This specification ensures that the reactor will not be made critical with the Reactor Coolant System average temperature less than 551*F.
This limitation is required to ensure: (1) the moderator temperature coefficient is within it analyzed temperature range, (2) the trip instrumentation is within its normal operating range, (3) the pressurizer is capable of being in an OPERABLE status with a steam bubble, and (4) the reactor vessel is above its minimum RT temperature.
m 3/4.1.1.5' CORE REACTIVITY The core is considered to be operating within acceptable design limits when measured core reactivity is within 11% ak/k of the predicted value at steady state thermal conditions. Deviations from the design limit are normally detected by comparing predicted and measured steady state RCS critical boron concentrations. The different between measured and predicted values would be approximately 100 ppm (depending on the boron worth) before
'the design limit is reached. These values are well within the uncertainty limits for analysis of boron concentration samples.
Therefore, spurious violations of the design limit due to uncertainty in measuring the RCS boron concentration are unlikely.
The acceptance criteria for core reactivity (11% Ak/k of the predicted value) ensures plant operation is maintained within the assumptions of the safety analyses.

CORE REACTIVITY (Continued) 4 Accurate prediction of core reactivity is either an explicit or implicit assumption in the accident analysis evaluations. Therefore, every accident evaluation is dependent upon accurate evaluation of core reactivity.
SDM and j
reactivity transients, such as control rod withdrawal accidents or rod j
ejection accidents, are very sensitive to accurate prediction of core reactivity. These accident analysis evaluations rely on computer codes that
,^
have been qualified against available test data, operating plant data, and J
analytical benchmarks. Monitoring reactivity balance additionally ensures that the nuclear methods provide an accurate representation of the core j
reactivity.
Design calculations and safety analyses are performed for each fuel cycle.
These are used to predetermine reactivity behavior and RCS boron 1
ll concentration requirements for reactivity control during fuel depletion.
The comparison between measured and predicted initial core reactivity i
provides a normalization for the calculational models used to predict core reactivity.
If the measured and predicted RCS boron concentrations for identical core conditions at beginning of life (BOL) do not agree, then the assumptions used in the reload cycle design analysis or requirements may not be accurate.
If reasonable agreement between measured and predicted core reactivity exists at BOL, then the prediction may be normalized to the measured boron concentration. Thereafter, any significant deviations in the measured boron concentration from the predicted boron letdown curve that develop during fuel depletion may be an indication that the calculational model is not adequate for core burnups beyond BOL, or that an unexpected change in core conditions has occurred.
The normalization of predicted RCS boron concentration to the measured value is typically performed after reaching RTP following startup from a refueling outage, with the control rods in their normal positions for power operation.
The normalization is performed at BOL conditions, so that core j
reactivity relative to predicted values can be continually monitored and evaluated as core conditions change during the cycle.
)
Should an anomaly develop between measured and predicted core reactivity, an evaluation of the core design and safety analysis must be performed. Core
}
conditions are evaluated to determine that they are within the bounds of the safety analysis, and safety analysis calculational models are reviewed to verify that they are adequate for representation of the co're conditions.

Following evaluations of the core design and safety analysis, the cause j
of the reactivity anomaly may be resolved.
If the cause of the reactivity anomaly is a mismatch in core conditions at the time of RCS boron concentration sampling, then a recalculation of the RCS boron concentration requirements may be performed to demonstrate that core reactivity is behaving as expected.
If an unexpected physical change in the condition of the core has occurred, it must be evaluated and corrected, if possible.
If the cause of the reactivity anomaly is in the calculation technique, then the calculational models must be revised to provide more accurate predictions.
If any of these results are demonstrated, and it is concluded that the reactor core is acceptable for continued operation,then the boron letdown curve may be renormalized and power operation may continue.
If operational restriction or additional surveillance requirements are necessary to ensure the reactor core is acceptable for continued operation, then they must be defined.

OPERABILITY of the control rod position indicators is required to determine control rod positions and thereby ensure compliance with the control rod alignment and insertion limits.
Verification that the Digital Rod Position Indicator agrees with the demanded position j
within i 12 steps at 24, 48, 120, and 228 steps withdrawn for the Control Banks and 18, 210 and 228 steps withdrawn for the Shutdown Banks provides assurances that the Digital Rod Position Indicator is operating correctly over the full range of indication.
Since the Digital Rod Position System does not indicate the actual shutdown rod position between 18 steps and 210 steps, only points in the indicated ranges are picked for verification of agreement with demanded position.
for purposes of determining compliance with Specificatien 3.1.3.1, any immovability of a control rod invokes ACTION Statement 3.1.3.1.a.
Before utilizing ACTION Statement 3.1.3.1.c, the rod control urgent failure alarm must be illuminated or an electrical problem must be detected in the rod control system. The rod is considered trippable if the rod was demonstrated OPERABLE during the last performance of Surveillance Requirement 4.1.3.1.2 and met the rod drop time criteria during the last performance of Surveillance l

The ACTION statements which permit limited variations from the basic

These restrictions provide assurance of fuel rod integrity during continued operation.
In addition, those safety analyses affected by a misaligned rod are reevaluated to confirm that the results remain valid during future operation.
The power reduction and shutdown time limits given in ACTION statements 3.1.3.2.a.2, 3.1.3.2.b.2, and 3.1.3.2.c.2, respectively, are initiated at the l
time of discovery that the compensatory actions required for POWER OPERATION can no longer be met.
The maximum rod drop time restriction is consistent with the assumed rod drop time used in the safety analyses. Measurement with T greater than or equal to 551*F and with all reactor coolant pumps operatin,g, ensures that the measured drop times will be representative of insertion times experienced during a Reactor trip at operating conditions.

BASES 3/4.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION The plant is designed to' operate with all reactor coolant loops in operation and maintain DNBR above the safety analysis limit DNBR (1.32) during all normal operations and anticipated transients.
In MODES 1 and 2 with one
. reactor coolant loop not in operation this specification requires that the l
plant be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
In MODE 3, two reactor coolant loops provide sufficient heat removal capability for removing decay heat even in the event of a bank withdrawal accident;-however, single failure considerations require that three loops be OPERABLE. A single reactor coolant loop provides sufficient heat removal if a bank withdrawal accident can be prevented; i.e., by opening the Reactor Trip i
System breakers.
In MODE 4, and in MODE 5 with reactor coolant loops filled,'a single reactor coolant loop or RHR loop provides sufficient heat removal capability for removing decay heat; but single failure considerations require that at least two loops (either RHR or RCS) be OPERABLE.
.In MODE 5 with reactor coolant loops not filled, a single RHR loop provides sufficient heat removal capability for removing decay heat; but single failure considerations, and the unavailability of the steam generators j
as a heat removing component, require that at least two RHR loops be OPERABLE.
I The operation.of one reactor coolant pump (RCP) or one RHR pump provides adequate flow to ensure mixing, prevent stratification and produce gradual reactivity changes during boron concentration reductions in the Reactor Coolant System.
The reactivity change rate associated with boron reduction will, therefore, be within the capability of operator recognition and control.
Addition of borated water with a concentration greater than or equal to the minimum required RWST concentration but less than the actual RCS baron concentration shall not be considered a reduction in boron concentration.
The restrictions on starting a reactor coolant pump in MODES 4 and 5 are provided to prevent RCS pressure transients, caused by energy additions from the Secondary Coolant System, which could exceed the limits of Appendix G to 10 CFR Part 50.
The RCS will be protected against overpressure transients and will not exceed the limits of Appendix G by restricting starting of the RCPs to when the secondary water temperature of each steam generator is less than 50*F above each of the RCS cold leg temperatures.
3/4.4.2 SAFETY VALVES The pressurizer Code safety valves operate to prevent the RCS from being pressurized above its Safety Limit of 2735 psig.

I During operation, all pressurizer Code safety. valves must be OPERABLE to prevent the RCS from being pressurized above its Safety Limit of 2735 psig.
The combined relief capacity of all of these valves is greater than the maximum surge rate resulting from a complete. loss-of-load assuming no Reactor trip and also assuming no operation of the power-operated relief valves or
. steam dump valves.
I' Demonstration of the safety valves' lift settings will' occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Code.
Addition to the RCS of borated water with a concentration greater than or equal to the minimum required RWST concentration shall not be considered a
-positive reactivity change. Cooldown of the RCS for restoration of 3perability of a pressurizer code safety valve, with a negative moderator temperature coefficient, shall not be considered a positive reactivity change provided the RCS is borated to the COLD SHUTDOWN, xenon-free conditions per specification 3.1.1.1.

~
The 12-hour periodic surveillance is sufficient to ensure that the parameter is. restored to within its limit following expected transient opera-tion. The maximum water volume also ensures that a steam bubble is formed and thus the RCS is not a hydraulically solid system. The requirement that a minimum number of pressurizer heaters be OPERABLE enhances the capability of the plant to control Reactor Coolant System pressure and establish natural circulation.
3/4.4.4 RELIEF VALVES The power-operated relief valves (PORVs) and' steam bubble function to relieve RCS pressure during all design transients up to and including the.
design step load decrease with steam dump. Operation of the PORVs minimizes the undesirable opening of the spring-loaded pressurizer code safety valves.
1 Each PORV has a remotely operated block valve to provide a positive shutoff capability should a relief valve become inoperable.
The PORVs are equipped with automatic actuation circuitry and manual l
control capability. Because no credit for automatic PORV operation is taken in the USAR analyses for MODE 1, 2 and 3 transients, the PORVs are considered OPERABLE in either the manual or automatic mode.
The automatic mode is the preferred configuration, as this provides pressure relieving capability without reliance on operator action.

The lead factor represents the relationship between the fast neutron flux l

Allowable pressure-temperature relationships for various heatup and cooldown rates are calculated using methods derived from Appendix G in Section III of the ASME Boiler and Pressure Vessel Code as required by Appendix G to 10 CFR Part 50.
The general method for calculating heatup and cooldown limit curves is based upon the principles of the linear elastic fracture mechanics (LEFM) technology.
In the calculation procedures a semi-elliptical surface defect with a depth of one-quarter of the wall thickness, T, and a length of 3/2T is assumed to exist at the inside of the vessel wall as well as at the outside of the vessel wall. The dimensions of this postulated crack, referred to in i
Appendix G of ASME Section III as the reference flaw, amply exceed the current capabilities of inservice inspection techniques. Therefore, the reactor operation limit curves developed for this reference crack are conservative and provide sufficient safety margins for protection against nonductile failure.

A composite curve is constructed based on a point-by-point comparison of the steady-state and finite heatup rate data. At any given temperature, the allowable pressure is taken to be the lesser of the three values taken from the curves under consideration.
The use of the composite curve is necessary to set conservative heatup limitations because it is possible for conditions to exist such-that over the course of the heatup ramp the controlling condition switches from the inside to the outside and the pressure limit must at all times be based on analysis of the most critical criterion.
The OPERABILITY of two PORVs, or two RHR suction relief valves, or an RCS vent opening of at least 2 square inches ensures that the RCS will be protected from pressure transients which could exceed the limits of Appendix G to 10 CFR Part 50 when one or more of the RCS cold legs are less than or equal to 368'F.
Either PORV or either RHR suction relief valve has adequate relieving capability to protect the RCS from overpressurization when the transient is limited to either: (1) the start of an idle RCP with the secondary water temperature of the steam generator less than or equal to 50*F above the RCS cold leg temperatures, or (2) the start of a centrifugal charging pump and its, injection into a water solid RCS.
In addition to opening RCS vents to meet the requirement of Specification 3.4.9.3c., it is acceptable to remove a pressurizer Code safety valve, open a PORV block valve and remove power from the valve operator in conjunction with disassembly of a PORV and removal of its internals, or otherwise open the RCS.

l REACTOR COOLANT SYSTEM-BASES COLD OVERPRESSURE l
The Maximum Allowed PORV Setpoint for the' Cold Overpressure Mitigation System (COMS) is derived by analysis which models the performance of the COMS assuming Various mass input and heat input transients.
Operation with a PORV Setpoint less than or equal to the maximum Setpoint ensures that Appendix G criteria will not be violated with consideration for: (1) process and instru-mentation uncertainties; and (2) single failure.
To ensure mass and heat input transients more severe than those assumed cannot occur, Technical Specifications require lockout of both Safety Injection pumps and all but one centrifugal charging pump while in MODES 4, 5, and 6 with the reactor vessel head installed and disallow start of an RCP if secondary coolant temperature is more than 50*F above reactor coolant temperature.
Exceptions to these requirements are accept-able as described below.
Operation above 350*F but less than 375'F with only one centrifugal charging pump OPERABLE and no Safety Injection pumps OPERABLE is allowed for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
As shown by analysis LOCAs. occurring at low temperature, low pressure conditions can be successfully mitigated by the operation of a single centrifugal charging pump and a single RHR pump with no credit for accumulator injection.
Given the short time duration and the condition of having only one centrifugal charging pump OPERABLE is allowed and the probability of a LOCA occurring during this time, the failure of the single centrifugal charging pump is not assumed.
Operation below 350'F but greater than 325'F with all centrifugal charging and Safety Injection pumps OPERABLE is allowed for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
During low pressure, low temperature operation all automatic Safety Injection actuation signals except Containment Pressure - High are blocked.
In normal conditions a single failure of the ESF actuation circuitry will result in the starting of at most one train of Safety Injection (one centrifugal charging pump, and one Safety Injectionpump).
For temperatures above 325*F, an overpressure event occurring as a result of starting two pumps can be successfully mitigated by operation of both PORVs without exceeding Appendix G limit.
Given the short time duration that this condition is allowed and the low probability of a single failure causing an overpressure event during this time, the single failure of a PORV.is not assumed.
Initiation of both trains of Safety Injection during this 4-hour time frame due to operator error or a single failure occurring during testing of a redundant channel are not considered to be credible accidents.
Although CONS is required to be OPERABLE when RCS temperature is less than 368'F, operation with all centrifugal charging pumps and both Safety Injection pumps OPERABLE is acceptable when RCS temperature is greater than 350*F.
Should an inadvertent Safety Injection occur above 350'F, a sin capacity to relieve the combined flow rate of all pumps.gle PORV has sufficient Above 350*F two RCPs and all pressure safety valves are required to be OPERABLE.

Should an overpressure event occur in these conditions, the presurizer safety valves provide acceptable and redundant overpressure protection.

j 3/4.6.1.4 INTERNAL PRESSVRE The limitations on containment internal pressure ensure that: (1) the containment structure is prevented from exceeding its design negative pressure differential with respect to the outside atmosphere of 3.0 psig, and (2) the containment peak pressure does not exceed the design pressure of 60 psig during steam line break conditions.
The maximum peak pressure expected to be obtained from a steam line break event is 48.9 psig. The limit of 1.5 psig for initial positive containment pressure will limit the total pressure to 50.4 psig, which' is less than design pressure and is consistent with the safety analyses.

3/4.6.1.7 CONTAINMENT VENTILATION SYSTEM The 36-inch containment purge supply and exhaust isolation valves are required to be closed and blank flanged during plant operations since these
. valves have not been demonstrated capable of closing during a LOCA or steam line break accident. Maintaining these valves closed and blank flanged during plant operation ensures that excessive quantities of radioactive material will not be released via the Containment Purge System.' To provide assurance that tiie 36-inch containment valves cannot be inadvertently opened, the valves are blank flanged.
The use of the containment mini-purge lines is restricted to the 18-inch purge supply and exhaust isolation valves since, unlike the 36-inch valves, the 18-inch valves are capable of closing during a LOCA or steam line break accident. Therefore, the SITE B0UNDARY dose guideline values of 10 CFR Part 100 would not be exceeded in the event of an accident during containment purging operation. Operation will be limited to 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> during a calendar year. The total time the Containment Purge (vent) System isolation valves may be open during MODES 1, 2, 3, and 4 in a calendar year is a function of anticipated need and operating experience. Only safety-related reasons, e.g.,
containment pressure control or the reduction of airborne radioactivity to facilitate personnel access for surveillance and maintenance activities, should be used to support the additional time requests. Only safety-related reasons should be used to justify the opening of these isolation valves during MODES 1, 2, 3 and 4, in any calendar year regardless of the allowable hours.
Leakage integrity tests with a maximum allowable leakage rate for containment purge supply and exhaust supply valves will provide early indication of resilient material seal degradation and will allow opportunity for repair before gross leakage failures could develop.
The 0.60 L leakage limit shall not _ be exceeded when the leakage rates determined by the leakage l
integrity tests of these valves are added to the previously determined total for all valves and penetrations subject to Type B and C tests.

The pressure reduction and resultant lower containment leakage rate are consistent with the assumptions used in the safety analyses.
i The Containment Spray System and the Containment Cooling System are i
redundant to each other in providing post-accident cooling of the containment
-atmosphere. However, the Containment Spray System also provides a mechanism i
for removing iodine from the containment atmosphere and therefore the time, 1
requirements for restoring an inoperable Spray System to OPERABLE status have been maintained consistent with that assigned other inoperable ESF equipment.
3/4.6.2.2 SPRAY ADDITIVE SYSTEM The OPERABILITY of the Spray Additive System ensures that sufficient Na0H is added to the containment spray in the event of a LOCA. The limits on Na0H i
volume and concentration ensure a pH value of between 8.5 and 11.0 for the 4
solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic l
stress corrosion on mechanical systems and components. The contained solution
[
volume limit includes an allowance for solution not usable because of tank discharge line location or other physical characteristics.
The educator flow test of 52 gpm with RWST water is equivalent to 40 gpm Na0H solution. These assumptions are consistent with the iodine removal efficiency assumed in the safety analyses.
3/4.6.2.3 CONTAINMENT COOLING SYSTEM The OPERABILITY of the Containment Cooling System ensures that: (1) the containment air temperature will be maintained within limits during normal operation, and (2) adequate heat removal capacity is available when operated in conjunction with the Containment Spray Systems during post-LOCA conditions.
The required design cooling water flow to the Containment Cooling System is verified by the surveillance testing requirements of Specification 4.6.2.3(b) which is performed at 18 month intervals. The testing requirements of Specification 4.6.2.3(a), performed at 31 day intervals, ensure that the fan units and the cooling water flow paths (supply and return) from the Essential Service Water System headers are OPERABLE.
I The Containment Cooling System and the Containment Spray System are redundant to each other in providing post accident cooling of the containment atmosphere. As a result of this redundancy in cooling capability, the allowabic out-of-service time requirements for the Containment Cooling System have been appropriately adjusted.

Containment isolation within the time limits specified for those isolation valves designed to close automatically ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA.
3/4.6.4 COMBUSTIBLE GAS CONTROL The OPERABILITY of the equipment and systems required for the control of l
hydrogen gas ensures that this equipment will be available to maintain the hydrogen concentration within containment below its flammable limit during post-LOCA conditions.. Either recombiner unit is capable of controlling the expected hydrogen generation associated with: (1) zirconium-water reactions, (2) radiolytic decomposition of water, and (3) corrosion of metals within containment. Operation of the Emergency Exhaust System with the heaters operating for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters. These Hydrogen Control Systems are consistent with the recommendations of Regulatory Guide 1.7, " Control of Combustible Gas Concentrations in Containment Following a Loss-of-Coolant Accident,"-
Revision 2, November 1978.

Adequate mixing of the containment atmosphere following a LOCA is ensured by natural circulation without reliance on a hydrogen mixing systems.

The OPERABILITY of the main steam line isolation valves ensures that no more than one steam generator will blowdown in the event of a steam line 4
rupture. This restriction is required to: (1) minimize the positive reactivity effects of the Reactor Coolant System cooldown associated with the blowdown, and (2) limit the pressure rise within containment in the event the steam line rupture occurs within containment. The OPERABILITY of the main i
steam isolation valves within the closure times of the Surveillance Requirements are consistent with the assumptions used in the safety analyses.
3.4.7.1.6 STEAM GENERATOR ATMOSPHERIC RELIEF VALVES
\\
The operability of the main steamline atmospheric relief valves (ARV's) l ensures that reactor decay heat can be dissipated to the atmosphere in the j
event of a steam generator tube rupture and loss of offsite power and that the
, Reactor Coolant System can be cooled down for Residual Heat Removal System a
operation. The number of required ARV's assures that the subcooling can be achieved, consistent with the assumptions used in the steam generator tube l
rupture analysis, to facilitate equalizing pressures between the Reactor Coolant System and the faulted steam generator.
For cooling the plant to RHR initiation conditions, only one ARV is required.
In this case, with three ARV's operable, if the single failure of one ARV occurs and anothar ARV is assumed to be associated with the faulted steam generator, one ARV remains available for required heat removal.
l Each ARV is equipped with a manual block valve (in the auxiliary building) to provide a positive shutoff capability should an ARV develop leakage. Closure of the block valves of all ARV's because of excessive seat leakage does not endanger the reactor core; consistent with plant accident and transient analyses, decay heat can be dissipated with the main steamline 4
i safety valves or a block valve can be opened manually in the auxiliary building and the ARV can be used.to control release of steam to the astmosphere.
For the steam generator tube rupture event, primary to secondary leakage can be terminated by depressurizing the Reactor Coolant System with the pressurizer power operated relief yalves.

The redundant cooling capacity of this system, assuming a single failure, is consistent with i
the assumptions used in the safety analyses.
Each independent CCW loop contains two 100% capacity pumps and, therefore, the failure of one pump does not affect the OPERABILITY of that loop.

3/4.7.5 ULTIMATE HEAT SINK The limitations on the ultimate heat sink level and temperature ensure that sufficient cooling capacity is available either to: (1) provide normal cooldown of the facility or (2) mitigate the effects of accident conditions within acceptable limits.
i The limitations on minimum water level and maximum temperature are based on providing a 30-day cooling water supply from the Essential Service Water pumps to safety-related equipment without exceeding its design basis temperature and is consistent with the recommendations of Regulatory Guide 1.27, " Ultimate Heat Sink for Nuclear Plants," March 1974.
3/4.7.6 CONTROL ROOM EMERGENCY VENTILATION SYSTEM The OPERABILITY of the Control Room Emergency Ventilation System ensures that: (1) the ambient air temperature does not exceed the allowable temperature for continuous-duty rating for the equipment and instrumentation cooled by this system, and (2) the control room will remain habitable for operations personnel during and following all credible accident conditions.
Operation of the system with the heaters operating to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the charcoal adsorbers and HEPA filters. The OPERABILITY of this system in conjunction with control room design provisions is based on limiting the radiation exposure to personnel occupying the control room to 5 rems or less whole body, or its equivdent.
This limitation is consistent with the requirements of General Design Criterion 19 of Appendix A, 10 CFR Part 50. ANSI N510-1975 and N510-1980 will be used as procedural guides for surveillance testing.

3/4,9 REFUELING OPERATIONS BASES 3/4.9.1 BORON CONCENTRATION The limitations on reactivity conditions during REFUELING ensure that:
(1) the reactor will remain subtritical during CORE ALTERATIONS, and (2) a uniform boron concentration is maintained for reactivity control in the water volume having direct access to the reactor vessel.
The limitation on Keff of no greater than 0.95 is sufficient to prevent reactor criticality during refueling operations.
The locking closed of the required valves during refueling operations precludes the possibility of uncontrolled boron dilution of the filled portions of the Reactor Coolant System.
This action prevents flow to the RCS of unborated water by closing flow paths from sources of unborated water.
These limitations are consistent with the initial conditions assumed for the boron dilution incident in the safety analyses.
3/4.9.2 INSTRUMENTATION The OPERABILITY of the Source Range Neutron Flux Monitors ensures that redundant monitoring capability is available to detect changes in the reactivity condition of the core.
When determining compliance with action statement requirements, addition to the RCS of borated water with a concentration greater than or equal to the minimum required RWST concentration shall not be considered to be a positive reactivity change.
3J4.9.3 DECAY TIME The minimum requirement for reactor subtriticality prior to movement of irradiatea fuel assemblies in the reactor vessel ensures that sufficient time has elapsed to allow the radioactive decay of the short-lived fission p r out.c t s.
This decay time is consistent with the assumptions used in the safety analyses.
3 4.9.4 CONTAINMENT BUILDING PENETRATIONS The requirements on containment building penetration closure and OPERABILITY ensure that a release of radioactive material within containment will be restricted from leakage to the environment.
The OPERABILITY and closure restrictions are sufficient to restrict radioactive material release from a fuel element rupture based upon the lack of containment pressurization potential while in the REFUELING MODE.
The OPERABILITY of this system ensures the containment purge penetrations will be automatically isolated upon detection of high radiation levels within containment.
The OPERABILITY of this system is required to restrict the release of radioactive materials from the containment atmosphere to the environment.
Equivalent isolation methods for the emergency personnel escape lock and containment wall penetrations ensure releases from containment are prevented for credible accident scenarios.
The isolation techniques must be approved by an engineering evaluation and may include use of a material that can provide a temporary, pressure tight seal capable of maintaining the integrity of the penetrations and airlock to restrict the release of radioactive material from a fuel element rupture.

The minimum of 1000 gpm allows flow rates which provide additional margin against vortexing at the RHR pump suction while in a reduced RCS inventory condition.
Addition of borated water with a concentration greater than or equal to the minimum required RWST '... centration but less than the actual RCS boron concentration shall not be considered a reduction in boron concentration.
The requirement to have two RHR loops OPERABLE when there is less than 23 feet of water above the reactor vessel flange ensures that a single failure of the operating RHR loop will not result in a complete loss of RHR capability. With the reactor vessel head removed and at least 23 feet of water above the reactor vessel flange, a large heat sink is available for core cooling. Thus, in the event of a failure of the operating RHR loop, adequate time is provided to initiate emergency procedures to cool the core.
