SAFETY LIMITS B 2.1 i
BASES l
f 2J, SAFETY LIMITS The Specifications in Section 2.1 establish operating parameters to assure that specified receptable i
fuel design limits are not exceeded during steady state operation, normal operational transients, and anticipated operational occurrences (AOOs). These parameters are based on the Safety Limits requirements stated in the Code of Federal Regulations,10 CFR 50.36(c)(1):
" Safety limits for nuclear reactors are limits upon important process variables that are i
found to be necessary to reasonably protect the integrity of certain of the physical barriers i
that guard against the uncontrolled release of radioactivity."
l 4
The fuel cladding, reactor pressure vessel and primary system piping are the principal barriers to the release of radioactive materials to the environs. Safety Limits are established to protect the Integrity of these barriers during normal plant operstions and anticipated transients. The fuel cladding integrity limit is set such that no fuel damag3 is calculated to occur as a result of an AOO. l Because fuel damage is not directly observable, a step-back approach is used to establish a Safety
}
Limit for the MINIMUM CRITICAL POWER RATIO (MCPR) that represents a conservative margin j
relative to the conditions required to maintain fuel cladding integrity.
The fuel cladding is one of the physical boundaries which separate radioactive materials from the i
environs. The integrity of the fuel cladding is related to its relative freedom from perforations or j
cracking. Although some corrosion or use-related cracking may occur during the life of the cladding, fission product migration from this source is incrementally cumulative and continuously measurable. Fuel cladding perforations, however, can result from thermal stresses which occur from reactor operation significantly above design conditions and the protection system safety settings. While fission product migration from cladding perforations is just as measurable as that from use-related cracking, the thermally caused cladding perforations signal a threshold beyond which still greater ther~ al stresses may cause gross rather than incremental cladding deterioration.
m Therefore, the fuel cladding integrity Safety Limit is defined with margin to the conditions which would produce onset of transition boiling (MCPR of 1.0). These conditions represent a significant departure from the condition intended by design for planned operation. Therefore, the fuel cladding integrity Safety Limit is established such that no calculated fuel damage shall result from an abnormal operational transient. This is accomplished by selecting a MCPR fuel cladding integrity Safety Limit which assures that during normal operation and AOOs, at least 99.9% of the fuel rods in the care do not experience transition boiling.
Exceeding a Safety Limit is cause for unit shutdown and review by the Nuclear Regulatory Commission (NRC) before resumption of unit operation. Operation beyond such a limit may not in itself result in serious consequences but it indicates an operational deficiency subject to regu'atory review.

SAFETY LIMITS B 2.1 1

BASES l
l 21A THERMAL POWER. Low Pressure or low Flow 1
i This fuel cladding integrity Safety Limit is established by establishing a limiting condition on core
)
4 THERMAL POWER developed in the following method. At pressures below 800 psia (~785 psig),
the core elevation pressure drop (0% power,0% flow) is greater than 4.56 psi. At low powers and flows, this pressure differential is maintained in the bypass region of the core. Since the pressure I
i drop in the bypass region is essentially all elevation head, the core pressure drop at low powers and I
j flows will always be greater than 4.56 psi. Analyses show that with a bundle flow of 28 x 103 lb/hr, bundle pressure drop is nearly independent of bundle power and he's a value of 3.5 psi.
)
Thus, the bundle flow with a 4.56 psi driving head will be greater than 28 x 108 lb/hr. Full scale ATLAS test data taken at pressures from 14.7 psia to 800 psia indicate that the fuel assembly j
critical power at this flow is approximately 3.35 MWt. At 25% of RATED THERMAL POWER, the l
peak powered bundle would have to be operating at 3.86 times the average powered bundle in i
j order to achieve this bundle power. Thus, a core thermal power limit of 25% for reactor pressures below 785 psig is conservative.

to occur if the limit is not violated. Since the pa'ameters which result in fuel damage are not j
}
directly observable during reactor operation, the thermal and hydraulic conditions resulting in j
departure from nucleate boiling have been used to mark the beginning of the region where fuel i
damage could occur. Although it is recognized that a departure from nucleate boiling would not 2
necessarily result in damage to BWR fuel rods, the critical power ratio (CPR) at which boiling I
transition is calculated to occur has been adopted as a convenient limit. However, the uncertainties in monitoring the core operating state and in the procedures used to calculate the critical power j
result in an uncertainty in the value of the critical power. Therefore, the fuel cladding integrity Safety Limit is defined such that, with the limiting fuel assembly operating at the MCPR Safety i
Limit, more than 99.9% of the fuel rods in the core are expected to avoid boiling transition. This includes consideration of the power distribution within the core and all uncertainties.
The margin between a MCPR of 1.0 (onset of transition boiling) and the Safety Limit,is derived from a detailed statistical analysis which considers the uncertainties in monitoring the care operating state, including uncertainty in the critical power correlation. Because the trrnsition boiling correlation is based on a significant quantity of practical test data, there is a very high confidence that operation of a fuel assembly at the condition where MCPR is equal'.o the fuel cladding integrity Safety Limit would not produce transition boiling. In addition, during single recirculation loop operation, the MCPR Safety Limit is increased by 0.01 to conser/atively account for increased uncertainties in the core flow and TIP measurements.
However, if transition boiling were to occur, cladding perforation would not necessarily be j
expected. Significant test data accumulated by the NRC and private organizations indicate that the use of a boiling transition limitation to protect against cladding failure is a very conservative OUAD CITIES - UNITS 1 & 2 B22 Amendment Nos.177 & 175

12 LIMITING SAFETY SYSTEM SETTINGS The Specifications in Section 2.2 establish operational settings for the reactor protection system l
instrumentation which initiates the automatic protective action at a level such that the Safety Limits will not be exceeded. These settings are based on the Limiting Safety System Settings requirements stated in the Code of Federal Regulations,10 CFR 50.36(c)(1):
" Limiting safety system settings for nuclear reacters are settings for automatic protective devices related to those variables having significtint safety functions. Where a limiting safety system setting is specified for a variable on which a safety limit has been placed, the setting must be so chosen that au.omatic protective action will correct the abnormal situation before a safety limit is excee ied. "
124 Reactor Protection System Instr.imentation Setooints The Reactor Protection System (RPS) instrumentation setpoints specified in the table are the values at which the reactor scrams are set for each parameter. The scram settings have been selected to l
ensure that the reactor core and reactor coolant system are prevented from exceeding their Safety Limits during normal operation and design basis anticipated operational occurrences and assist in mitigating the consequences of accidents. Conservatism incorporated into the transient analysis is documented by each approved fuel vendor. The bases for individual scram settings are discussed in the following paragraphs.
1.
Intermediate Renae~ Monitor. Neutron Flux - Hiah The IRM system consists of eight cham %rs, four in each of the reactor protection system logic CHANNELS. The IRM is a 5 decade,10 range, instrument which covers the range of power level between that covered by the SRM and the APRM. The IRM scram setting at 120 of 125 divisions is active in each range of the IRM. For example, if the instrument were on Range 1, the scram setting would be 120 divisions for that range; likewise, if the instrument were on Range 5, the scram would be 120 divisions on that range. Thus, as the IRM is ranged up to accommodate the increase in power level, the scram setting is also ranged up.
The m,et significant sources of reactivity change during the power increase are due to control rod withdrawal in order to ensure that the IRM provides adequate protection against the single rod withdrawal error, a range of rod withdrawal events has been analyzed. This analysis included starting the event at various power levels. The meu.,evere case involves an initial condition in which the reactor is just suberitical and the iRM system is not yet on scale.
Additional conservatism was taken in this analysis by assuming that the IRM CHANNEL closest to the withdrawn rod is bypassed. The results of this analysis show that the reactor is scrammed and peak local power is limited to 7.7% of rated bundle power, thus maintaining MCPR above the fuel l
cladding integrity Safety Limit. Based on the above analysis, the IRM povides protection against QUAD CITIES - UNITS 1 & 2 B 2-5 Amendment Nos.177 & 175 i

Averaos Power Ranae Monitor j
For operation at low pressure and low flow during Startup, a reduced power level, i.e., setdown, APRM scram setting of 15% of RATED THERMAL POWER provides adequate thermal margin
{
between the setting and the Safety Limit. The margin is adequate to accommodate anticipated j
maneuvers associated with power plant startup. Effects of increasing pressure at zero or low void content are minor; cold water from snurces available during startup are not much colder than that already in the system; temperature coefficients are small; and, control rod patterns are constrained to be uniform by operating procedures backed up by the rod worth minimizer. Of all possible sources of reactivity input, uniform control rod withdrawalis the most probable cause of significant power rise. Because the flux distribution associated with uniform rod withdrawals does not involve high local peaks, and because several rods must be moved to change power by a significant i
percentage of rated power, the rate of power rise is very slow. Generally, the heat flux is in near 1
equilibrium with the fission rate. In an assumed uniform rod withdrawal approach to the scram i
setting, the rate of power rise is no more than 5% of RATED THERMAL POWER per minute, and 3
the APRM system would be more than adequate to assure a scram before the power could exceed the Safety Limit. The 15% APRM setdown scram setting remains active until the mode switch is placed in the Run position.
i j,
The average power range monitoring (APRM) system, which is calibrated using heat balance data i
taken during steady state conditions, also provides a flow biased neutron flux which reads !n percent of RATED THERMAL POWER. Because fission chambers provide the basic input signels, 1
the APRM system responds directly to average neutron flux. During transients, the instantaneous rate of heat transfer from the fuel (reactor thermal power) is less than the instantaneous neutron j
flux due to the time constant of the fuel. During abnormal operational transients, the thermal j
ew*r of the fuel will be less than that indicated by the neutron flux at the scram setting.
l afses demonstrate that, with a 120% scram setting for dual recirculation loop operation, or j-with a 116.5% scram setting for single recirculation loop operation, none of the abnormal operational transients analyzed violates the fuel cladding integrity Safety Limit, and there is a 4
i substantial margin from fuel damage. One of the neutron flux scrams is flow dependent until it j
reaches the applicable setting where it is " clamped" at its maximum allowed value. The use of the l
flow referenced neutron flux scram setting provides additional margin beyond the use of a the fixed high flux scram setting alone.
An increase in the APRM scram setting would decrease the margin present before the fuel cladding integrity Safety Limit is reached. The APRM scram setting was determined by an analysis of margins required to provide.a reasonable range for maneuvering during operation. Reducing this
)
operating margin would increase the frequency of spurious scrams, which have an adverse effect on reactor safety because of the resulting thermal stresses. Thus, the APRM scram setting was selected because it provides adequate margin for the fuel cladding integrity Safety Limit, yet allows operating margin that reduces the possibility of unnecessary scrams.

LSSS B 2.2 BASES decrease as power is increased to 100% in comparison to the level outside the shroud, to a maximum of seven inches, due to the pressure drop across the steam dryer. Therefore, at 100%
power, an indicated water level of + 8 inches water level may be as low as + 1 inches inside the shroud which corresponds to 144 inches above the top of active fuel and 504 inches above vessel aero. The top of active fuelis defined to be 360 inches above vessel zero.
l 5.
Main Steam Line isolation Valve - Closure Automatic isolation of the main steam lines is provided to give protection against rapid reactor depressurization and cooldown of the vessel. When the main ateam line isolation valves begin to close, a scram signal provides for reactor shutdown so that high power operation at low reactor 1
pressures does not occur. With the scram setting at 10% valve closure (from full open), there is no appreciable increase in neutron flux during normal or inadvertent isolation valve closure, thus 3
providing protection for the fuel cladding integrity Safety Limit. Operation of the reactor at pressures lowr-than the MSIV closure setting requires the reactor mode switch to be in the Startup/ Hot Standby position, where protection of the fuel cladding integrity Safety Limit is provided by the IRM and APRM high neutron flux scram signals. Thus, the combination of main steam line low pressure isolation and the isolation valve closure scram with the mode switch in the Run position assures the availability of the neutron flux scram protection over the entire range of j
applicability of fuel cladding integrity Safety Limit.
6.
Main Steam Line Radiation - Hiah I
High radiation levels in the main steam line tunnel above that due to the normal nitrogen and I
oxygen radioactivity are an indication of leaking fuel. When high radiation is detected, a scram is initiated to mitigate the failure of fuel cladding. The scram setting is high enough above background radiation levels to prevent spurious scrams yet low enough to promptly detect gross failures in the fuel cladding. This setting is determined based on normal full power background (NFPB) radiation levels without hydrogen addition. With the injection of hydrogen into the i
feedwater for mitigation of intergranular stress corrosion cracking, the full power background levels may be significantly increased. The setting is sufficiently high to allow the injection of hydrogen I
without requiring an increase in the setting. This trip function provides an anticipatory scram to limit offsite dose consequences, but is not assumed to occur in the analysis of any design basis event.

INSTRUMENTATION B 3/4.2 I
BASES l
3/4,2 INSTRUMENTATION in addition to reactor protection instrumentation which initiates a reactor scram (Sections 2.2 and l
3/4.1), protective instrumentation has been provided which initiates action to mitigate the l
consequences of accidents which are beyond the operator's ability to control, or which terminates operator errors before they result in serious consequences. The objectives of these specifications are to assure the effectiveness of the protective instrumentation when required and to prescribe j
the trip settings required to assure adequate performance. As indicated, one CHANNEL may be l
required to be made inoperable for brief intervals to conduct required surveillance. Some of the settings have tolerances explicitly stated where the high and low values are both critical and may have a substantial effect on safety, it should be noted that the setpoints of other instrumentation, where only the high or low end of the setting has a direct bearing on safety, are chosen at a level l
away from the normal operating range to prevent inadvertent actuation of the safety system involved and exposure to abnormal situations. Surveillance requirements for the instrumentation are selected in order to demonstrate proper function and OPERABILITY. Additional instrumentation for REFUELING operations is identified in Sections 3/4.10.8.
l Current fuel designs incorporate slight variations in the length of the active fuel and, thus, the actual top of active fuel, when compared with the original fuel designs. Safety Limits, instrument water level setpoints, and associated LCOs refer to the top of active fuel. In these cases, the top of active fuelis defined as 360 inches above vessel zero. Licensing analyses, both accident and l
transient, utilize this definition for the automatic initiation and manualintervention associated with these events.
l 3/4.2.A isolation Actuation Instrumentation The isolation actuation instrumentation automatically initiates closure of appropriate isolation valves and/or dampers, which are necessary to prevent or limit the release of fission products from the reactor coolant system, the primary containment and the secondary containment in the event l
of a loss-of coolant accident or other reactor coolant pressure boundary (RCPB) leak. The parameters which result in isolation of the secondary containment also actuate the standby gas treatment system. The isolation instrumentation includes the sensors, relays, and switches that l
are necessary to cause initiation of primary and secondary containment and RCPB system isolation.
I Functional diversity is provided by monitoring a wide range of dependent and independent parameters. Redundant sensor input signals for each parameter are provided for initiation of isolation (one exception is standby liquid control system initiation).
The reactor low level instrumentation is set to trip at greater than or equal to 144 inches above the top of active fuel (which is defined to be 360 inches above vessel zero). This trip initiates closure of Group 2 and 3 primary containment isolation valves but does not trip the recirculation pumps.
For this trip setting and a 60 second valve closure time, the valves will be closed before perforation of the cladding occurs, even for the maximum break.

INSTRUMENTATION B 3/4.2 BASES 3/4.2.B Emeraencv Core Coolina System Actuation instrumentation The emergency core cooling system (ECCS) instrumentation generates signals to automatically actuate those safety systems which provide adequate core cooling in the event of a design basis transient or accident. The instrumentation which actuates the ECCS is generally arranged in a one-out-of-two taken twice logic circuit. The logic circuit is composed of four CHANNEL (s) and 1
each CHANNEL contains the logic from the functional unit sensor up to and including all relays which actuate upon a signal from that sensor. For core spray and low pressure coolant injection, the divisionally powered actuation logic is duplicated and the redundant components are powered i
from the other division's power supply. The single-failure criterion is met through provisions for redundant core cooling functions, e.g., sprays and automatic blowdown and high pressure coolant injection. Although the instruments are listed by system, in some cases the same instrument is i
used to send the actuation signal to more than one system at the same time.
For effective emergency core cooling during small pipe breaks, the high pressure coolant injection (HPCI) system must function since reactor pressure does not decrease rapidly enough to allow either core spray or the low pressure coolant injection (LPCI) system to operate in time. The automatic pressure relief function ir provided as a backup to HPCI, in the event HPCI does not operate. The arrangement of the tripping contacts is such as to provide this function when necessary and minimize spurious operation. The trip settings given in the specification are adequate to assure the above criteria are met. The specification preserves the effectiveness of the system during periods of maintenance, testing or calibration and also minimizes the risk of l
inadvertent operation, i.e., only one instrument CHANNEL out-of-service.
3/4.2 C ATWS - RPT instrumentation
.The anticipated transient without scram (ATWS) recirculation pump trip (RPT) provides a means of limiting the consequences of the unlikely occurrence of a failure to scram concurrent with the associated anticipated transient. The response of this plant to this postulated event falls within the bounds of study events in General Electric Company Topical Report NEDO 10349, dated March 1971 and NEDO24222, dated December 1979. Tripping the recirculation pumps adds negative reactivity by increasing steam voiding in the core area as core flow decreases.
3/4.2.0 Reactor Core Isolation Coolino Actuation Instrumentation The reactor core isolation cooling system actuation instrumentation is provided to initiate actions to assure adequate core cooling in the event of reactor isolation from its primary heat sink and the loss of feedwater flow to the reactor vessel without providing actuation of any of the emergency l
core cooling equipment.

During MODE 5, adequate SDM is required to ensure that the reactor does not reach criticality during control rod withdrawals. An evaluation of each in-vessel fuel movement during fuelloading 4
i (including shuffling fuel within the core)is required to ensure adequate SDM is maintained during refueling. This evaluation ensures that the intermediate loading patterns are bounded by the safety analyses for the final core loading pattern. For example, bounding analyses that demonstrate adequate SDM for the most reactive configurations during the refueling may be performed to demonstrate acceptability of the entire fuel movement sequence. These bounding analyses include additional margins to the associated uncertainties. Spiral offload / reload sequences inherently satisfy the SR, provided the fuel assemblies are reloaded in the same configuration analyzed for the new cycle. Removing fuel from the core will always result in an increase in SDM.

j 3/4.3,C Control Rod OPERABILITY Control rods are the primary reactivity control system for the reactor. In conjunction with the Reactor Protection System, the control rods provide the means for reliable control of reactivity changes to ensure the specified acceptable fuel design limits are not exceeded. This specification, along with others, assures that the performance of the control rods in the event of an accident or transient, meets the assumptions used in the safety analysis. Of primary concern is the trippability of the control rods. Other causes for inoperability are addressed in other Specifications following this one. However, the inability to move a control rod which remains trippable does not prevent the performance of the control rod's safety function.
The specification requires that a rod be taken out-of service if it cannot be moved with drive pressure. Damage within the control rod drive mechanism could be a generic problem, therefore with a control rod immovable because of excessive friction or mechanical interference, operation of the reactor is limited to a time period which is reasonable to determine the cause of the inoperability and at the same time prevent operation with a large number of inoperable control rods.

However, 200 milliseconds rather than 120 milliseconds is conservatively assumed for this time interval in the transient analyses and is also included in the allowable scram insertion times specified in Specifications 3.3.D. 3.3.E and 3.3.F.
The performance of the individual control rod drives is monitored to assure that scram performance is not degraded. Transient analyses are performed for both Technical Specification Scram Speed (TSSS) and nominal scram speed (NSS) insertion times. These analyses result in the establishment of the cycle dependent TSSS MCPR limits and NSS MCPR limits presented in the COLR. Results of the control rod scram tests performed during the current cycle are used to determine the operating limit for MCPR. Following completion of each set of scram testing, the results will be compared with the assumptions used in the transient analysis to verify the applicability of the MCPR operating limits. Prior to the initial scram time testing for en operating cycle, the MCPR operating limits will be based on the TSSS insertion times.
Individual control rod drives with excessive scram times can be fully inserted into the core and de-energized in the manner of an inoperable rod drive provided the allowable number of inoperable control rod drives is not exceeded, in this case, the scram speed of the drive shall not be used as a basis in the re-determination of thermal margin requirements. For excessive average scram insertion times, only the individual control rods in the two-by two array which exceed the allowed average scram insertion time are considered inoperable.
The scram times for all control rods are measured at the time of each refueling outage. Experience with the plant has shown that control drive insertion times ' ary little through the operating cycle; v
hence no re assessment of thermal margin requirements is expected under normal conditions. The history of drive performance accumulated to date indicates that the 90% insertion times of new and overhauled drives approximate a normal distribution about the mean which tends to become skewed toward longer scram times as operating time is accumulated. The probability of a drive not exceeding the mean 90% insertion time by 0.75 seconds is greater than 0.999 for a normal distribution. The measurement of the scram performance of the drives surrounding a drive, which exceeds the expected range of scram performance, will detect local variations and also provide assurance that local scram time limits are not exceeded. Continued monitoring of other drives exceeding the expected range of scram times provides surveillance of possible anomalous performance.
The test schedule provides reasonable assurance of detection of slow drives before system deterioration beyorld the limits of Specification 3.3.C. The program was developed on the basis of the statistical approach outlined above and judgement. The occurrence of scram times within the limits, but significantly longer than average, should be viewed as an indication of a systematic problem with control rod drives, especially if the number of drives exhibiting such scram times exceeds eight, which is the allowable number of inoperable rods.

Reactivity Control B 3/4.3 BASES 3/4.3.J Control Rod Drive Housino Sucoort The control rod housing support restricts the outward movement of a control rod to less than 3 inches in the extremely remote event of a housing failure. The amount of reactivity which could be added by this small amount of rod withdrawal, which is less than a normal single withdrawal increment, will not contribute to any damage to the primary coolant system. The design basis is given in Section 4.6.3.5 of the UFSAR. This support is not required if the reactor coolant system is at atmospheric pressure, since there would then be no driving force to rapidly eject a drive housing.
3/4.3.K Scram Discharae Volume Vent and Drain Valves The scram discharge volume is required to be OPERABLE so that it will be available when needed to accept discharge water from the control rods during a reactor scram and willisolate the reactor coolant system from the containment when required. The operability of the scram discharge volume vent and drain valves assures the proper venting and draining of the volume, so that water accumulation in the volume does not occur. These specifications designate the minimum acceptable level of scram discharge volume vent and drain valve OPERABILITY, provide for the periodic verification that the valves are open, and for the testing of these valves under reactor scram conditions during each refueling outage.
3/4.3.L Rod Worth Minimizer Control rod withdrawal and insertion sequences are established to assure that the maximum insequence individual control rod or control rod segments which are withdrawn at any time during the fuel cycle could not have sufficient reactivity worth to result in a peak fuel enthalpy greater than 280 cal /gm in the event of a control rod drop accident. These low power (up to the LPSP) sequences are verified during the cycle reload analysis to ensure that the 280 cal /gm limit is not exceeded. The requirement that an operator follow these sequences is supervised by the RWM or a second technically qualified individual. These sequences are developed to limit reactivity worth of control rods and, together with the integral rod velocity limiters and the action of the control rod drive system, limit potential reactivity insertion such that the results of a control rod drop accident will not exceed a maximum fuel energy content of 280 cal /gm. The peak fuel enthalpy of 280 cal /gm is below the energy content at which rapid fuel dispersal and primary system damage have been found to occur based on experimental data. Therefore, the energy deposited during a postulated rod drop accident is significantly less than that required for rapid fuel dispersal.
The analysis of the control rod drop accident was originally presented in Sections 7.9.3,14.2.1.2, and 14.2.1.4 of the original SAR. Improvements in analytical capability have allowed a more refined analysis of the control rod drop accident which is discussed below.
Every operating cycle the peak fuel rod enthalpy rise is determined by comparing cycle specific parameters with the results of parametric analyses. This peak fuel rod enthalpy is then compared to the analysis limit of 280 cal /gm to demonstrate compliance for that operating cycle. If the cycle QUAD CITIES - UNITS 1 & 2 B 3/4.3 6 Amendment Nos.177 & 175

BASES specific parameters are outside the range used in the parametric study, an extension of the enthalpy may be required. Some of the cycle specific parameters used in the analysis are:
maximum control rod worth, Doppler coefficient, effective dolayed neutron fraction and maximum four bundle local peaking factor. The methodology used for the control rod drop accident analysis is NRC-approved and is part of the license bases referenced in Specification 6.9.A.6.
The rod worth minimizer provides automatic supervision to assure that out-of-sequence control rods will not be withdrawn or inserted, i.e., it limits operator deviations from planned withdrawal sequences (reference UFSAR Section 7.7.2). It serves as a backup to procedural control of control rod worth in the event that the rod worth minimizer is out-of-service when required, a second licensed operator or other technically qualified individual who is present at the reactor console can manually fulfill the control rod pattern conformance function of the rod worth minimizer. In this case, the normal procedural controls are backed up by independent procedural controls to assure conformance.
3/4.3.M Rod Block Monitor The rod block monitor (RBM) is designed to automatically prevent fuel damage in the event of erroneous rod withdrawal from locations of high power density during high. power operation. Two channels are provided, and one of these may be bypassed from the console for maintenance and/or testing. Tripping of one of the channels will block erroneous rod withdrawal soon enough to prevent fuel damage. This system backs up the operator, who withdraws control rods according to a written sequence. The specified restrictions with one channel out-of service conservatively assure that fuel damage will not occur due to rod withdrawal errors when this condition exists.

i The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code 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 safety valves i
are selected such that peak pressure in the nuclear system will not exceed the ASME Code limits l
for the reactor coolant pressure boundary. The overpressure protection system must accommodate j
the most severe pressurization transient. SPC methodology determines the most limiting pressurization transient each cycle. Evaluations have determined that the most severe transient is the closure of all the main steam line isolation valves followed by a reactor scram on high neutron flux. The analysis results demonstrate that the design safety valve capacity is capable of maintaining reactor pressure below the ASME Code limit of 110% of the reactor pressure vessel design pressure.
The relief valve function is not 'ssumed to operate in response to any accident, but are provided to a
remove the generated steam flow upon turbine stop valve closure coincident with failure of the turbine bypass system. The relief valve opening pressure settings are sufficiently low to prevent the need for safety valve actuation following such a transient.
Each of the five relief valves discharge to the suppression chamber via a dedicated relief valve discharge line. Steam remaining in the relief valve discharge line following closure can condense, creating a vacuum which may draw suppression pool water up into the discharge line. This condition is normally alleviated by the vacuum breakers; however, subsequent actuation in the presence of an elevated water leg can result in unacceptably high thrust loads on the discharge piping. To prevent this, the relief valves have been designed to ensure that each valve which closes will remain closed until the normal water level in the relief valve discharge line is restored.
The opening and closing setpoints are set such that allpressure induced subsequent actuation are limited to the two lowest set valves. These two valves are equipped with additional logic which functions in conjunction with the setpoints to inhibit valve reopening during the elevated water leg duration time following each closure.
Each safety / relief valve is equipped with diverse position indicators which monitor the tailpipe acoustic vibration and temperature. Either of these provide sufficient indication of safety / relief valve position for normal operation.
3/4.6.G Leakaoe Detection Systems The RCS leakage detection systems required by this specification are provided to monitor and detect leakage from the reactor coolant pressure boundary. Limits on leakage from the reactor coolant pressure boundary are required so that appropriate action can be taken before the integrity 3
of the reactor coolant pressure boundary is impaired. Leakage detection systems for the reactor coolant system are provided to alert the operators when leakage rates above the normal background levels are detected and also to supply quantitative measurement of leakage rates.

POWER DISTRIBUTION LIMITS B 3/4.11 BASES 3/4.11. A AVERAGE PLANAR LINEAR HEAT GENERATION RATE GE Fuel The calculational procedure used to establish the maximum APLHGR values uses NRC approved calculational models which are consistent with the requirements of Appendix K of 10 CFR Part 50.
The approved calculational models are listed in Specification 6.9.
The daily requirement for calculating APLHGR when THERMAL POWER is greater than or equal to 25% of RATED THERMAL POWER is sufficient since power distribution shifts are very slow when there have not been significant power or control rod changes. The requirement to calculate APLHGR within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after the completion of a THERMAL POWER increase of at least 15% of RATED THERMAL POWER ensures thermal limits are met after power distribution shifts while still allotting time for the power distribution to stabilize. The requirement for calculating APLHGR after initially determining a LIMITING CONTROL ROD PATTERN exists ensures that APLHGR will be known following a change in THERMAL POWER or power shape, that could place operation above a thermal limit.
This specification assures that the peak cladding temperature following the postulated design basis loss of-coolant accident will not exceed the limit specified in 10 CFR 50.46. The specification also assures that fuel rod mechanical integrity is maintained during normal and transient operations.
The peak cladding temperature (PCT) following a postulated loss-of-coolant accident is primarily a function of the average heat generation rate of all the rods of a fuel assembly at any axiallocation and is dependent only secondarily on tne rod-to-rod power distribution within an assembly. The peak clad temperature is calculated asou ning a LINEAR HEAT GENERATION RATE (LHGR) for the highest powered rod which is equal to or less than the design LHGR corrected for densification.
The APLHGR limits specified are equivalent to the LHGR of the highest powered fuel rod assumed in the LOCA analysis divided by its local peaking factor. A conservative multiplier is applied to the LHGR assumed in the LOCA analysis to account for the uncertainty associated with the measu:ement of the APLHGR.
SPC Fetl This specification assures that the peak cladding temperature of SPC fuel following a postulated 4
design basis loss of coolant accident will not exceed the Peak Cladding Temperature (PCT) and maximum oxidation limits specified in 10CFR50.46. The calcutational procedure used to establish the Average Planar Linear Heat Generation Rate (APLHGR) limits is based on a loss-of-coolant accident analysis.
The PCT following a postulated loss of coolant accident is primarily a function of the average heat generation rate of all the rods of a fuel assembly at any axial location and is not strongly influenced by the rod-to-rod power distribution within the assembly.

The scram settings must be adjusted to ensure that the TRANSiLNT LINEAR HEAT GENERATION RATE (TLHGR) is not violated for any power distribution. This is accomplished using FDLRC. The j
scram setting is decreased in accordance with the formula in Specification 3.11.11, when FDLRC is greater than 1.0.
I The adjustment may also be accomplished by increasing the gain of the APRM by FDLRC. This j
provides the same degree of protection as reducing the trip setting by 1/FDLRC by raising the initial i

i The required operating limit MCPR at steady state operating conditions as specified in Specification 3.11.C are derived from the established fuel cladding integrity Safety Limit MCPR, and an analysis i
of abnormal operational transients. For any abnormal operating transient analysis evaluation with the initial condition of the reactor being at the steady state operating limit, it is required that the resulting MCPR does not decrease below the Safety Limit MCPR at any time during the transient assuming instrument trip setting given in Specification 2.2.
i To assure that the fuel cladding integrity Safety Limit is not exceeded during any anticipated l'
abnormal operational transient, the most limiting transients are analyzed to determine which result i
in the largest reduction in the CRITICAL POWER RATIO (CPR). The type of transients evaluated are change of flow, increase in pressure and power, positive reactivity insertion, and coolant j
temperature decrease. The limiting transient yields the largest delta MCPR. When added to the i

BASES Safety Limit MCPR, the required minimum operating limit MCPR of Specification 3.11.C is obtained and presented in the CORE OPERATING LIMITS REPORT.
The steady state values for MCPR specified were determined using NRC approved methodology l
listed in Specification 6.9.
MCPR Operating Limits are presented in the CORE OPERATING LIMITS REPORT (COLR) for both Nominal Scram Speed (NSS) and Technical Specification Scram Speed (TSSS) insertion times. The negative reactivity insertion rate resulting from the scram plays a major role in providing the i
required protection against violating the Safety Limit MCPR during transient events. Faster scram l
insertion times provide greater protection and allow for improved MCPR performance. The application of NSS MCPR limits utilizes measured data that is faster than the times required by the Technical Specifications, while the TSSS MCPR limits provide the necessary protection for the slowest allowable average scram insertion times identified in Specification 3.3.E. The measured crcm times are compared with the nominal scram insertion times and the Technical Specification Scram Speeds. The appropriate operating limit is applied, as specified in the COLR.
l l
For core flows lecs than rated, the MCPR Operating Limit established in the specification is adjusted to provide protection of the Safety Limit MCPR in the event of an uncontrolled recirculation flow increase to the physicallimit of the pump. Protection is provided for manual and automatic flow control by applying the appropriate flow dependent MCPR limits presented in the COLR. The MCPR Operating Limit for a niven power / flow state is the greater value of MCPR as given by the rated conditions MCPR limit or the flow dependent MCPR limit. For automatic flow control, in addition to protecting the Safety Limit MCPR during the flow run-up event, protection is l
provided to prevent exceeding the rated flow MCPR Operating Limit during an automatic flow increase to rated core flow.
t
. At THERMAL POWER levels less than or equal to 25% of RATED THERMAL POWER, the reactor will be operating at minimum recirculation pump speed and the moderator void content will be very small. For all designated control rod patterns which may be emploved at this point, operating plant exponence indicates that the resulting MCPR value has considerabie margin. Thus, the i
demonstration of MCPR below this power levelis unnecessary. The daily requirement for calculating MCPR when THERMAL POWER is greater than or equal to 25% of RATED THERMAL POWER is sufficient since power distribution shitts are very slow when there have not been significant power or control rod changes. The requirement for calculating MCPR after initially determining that a LIMITING CONTROL ROD PATTERN exists ensures that MCPR will be known following a change in THERMAL POWER or power shape, regardless of magnitude, that could place operation above a thermallimit.
