BASES FOR SAFETY LIMITS 1.1 FUEL CLA0 DING-INTEGRITY A. FuelCladbinoIntegritylimitatReactorPressure>800psiaandCore .i Flow > 10% of Rated  !

The fuel cladding integrity Safety Limit is set such that no fuel damage is calculated to occur if the limit is not violated. Since the parameters which result in fuel damage are not directly observable during reactor operation the thermal and hydraulic conditions resulting in a departure from nucleate boiling have been used to mark the beginning of the region where fuel damage could occur. Although it is. recognized that a departure from nucleate Loiling would not necessarily result in damage to BWR fuel rods, the critical power at which boiling 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 result in an uncertainty in the value of the

' critical power. Therefore the fuel cladding integrity safety limit is defined as the critical power ratio in the limiting fuel assembly for which more than 99.9% of the fuel rods in the core are expected to avoid boiling transition considering the power distribution within the core and all uncertainties.

The MCPR Safety Limit is determined using a model that combines all of the uncertainties in operating parameters and the procedures used to calculate critical power. The probability of the occurrenr.e of boiling transition is determined using an NRC-approved critical power correlation.

This MCPR Safety Limit is increased for single-loop operation over the comparable two-loop value (Reference 2). Details of the fuel cladding integrity Safety Limit calculation are presented in Reference 1.

BASES FOR SAFETY LIMITS 1.1.B. Core Thermal Power Limit (Reactor Pressure < 800 osia)

At pressures below B00 psia, the core elevation pressure drop (0 power, i 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 drop in the bypass region is essentially all elevation head, the core pressure drop at low powers and flows will always be greater than 4.56 psi. Analyses show that with a flow of 28x108 lbs/hr bundle flow, bundle pressure drop is nearly independent of bundle power and has a value of 3.5 psi. Thus, the bundle flow with a 4.50 psi driving head will be greater than 28x10s lbs/hr. Full scale ATLAS test data taken at pressures from 14.7 psia to 800 psia indicate that the fuel assembly critical power at this flow is approximately 3.35 MWt. . With the design peaking factors this corresponds to a core thermal power of more than 50%. Thus, a core thermal power limit of 25% for reactor pressures

-below 800 nsia'is conservative.

C. Power ransient Plant safety analyses have shown that the scrams caused by exceeding any safety system setting will assure that the Safety Limit of 1.1. A or 1.1.8 will not be exceeded. Scram times are checked periodically to assure the insertion times are adequate. The thermal power transient resulting when a scram is accomplished other than by the expected scram signal.(e.g., scram from neutron flux following closure of the main turbine stop valves) does not necessarily cause fuel damage. However, for this specification a Safety Limit violation will be assumed when a scram is only accomplished by means of a backup feature of the plant design. The concept of not approaching a Safety Limit provided scram signals are operable is supported by the extensive plant safety analysis.

BASES FOR SAFETY LIMITS D. Reactor Water Level (Hot or Cold Shut'down Condition)

For the fuel in the core during periods when the reactor is shutdown,-consi-deration must be given to water level requirements due to the ef fect of decay heat. If the water. level should drop below the top of the fuel during .

this time,-the ability to remove decay heat is reduced. This reduction in cooling capability could lead to elevated cladding temperatures and clad perforation in the event that the water level became less than two-thirds of the core height. The Safety Limit has been established at 378 inches above vessel invert to provide a point which can be monitored and also provide adequate margin.

BASES FOR LIMITING CONDITIONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS B. Control Rods Limiting tonditions for Operation:

Specification 3.3.B.1 requires that a rod which cannot be moved with drive pressure be taken out of service by being disarmed electrically. To disarm the drive electrically, four amphenol type plug connectors are removed f rom the drive insert and withdrawal solenoids rendering the rod incapable of withdrawal. This procedure is equivalent to valving out the drive and is preferred because, in this condition, drive water cools and minimizes crud accumulation in the drive. Electrical disarming does not eliminate position indication. If the rod is f ully inserted and dis, armed electrically, it is in a safe position of maximum contribution to shutdown reactivity.

If it is disarmed electrically in a non-fully inserted position, that position shall be consistent with the shutdown reactivity.limitatior, stated in Specification 3.3.A. This assures that the core can be shutdown at all times with the remaining control rods, assuming the highest worth operable- l control rod does not inw-t. An allowable pattern for control rods disarmed  ;

electrically, which shall meet this Specification, will be determined and l made available to the operator. Also if damage within the control rod drive i mechanism and in particular, cracks in drive internal housing, cannot be i ruled out, then a generic problem affecting a number of drives cannot be ruled out. Circumferential cracks resulting from stress assisted intergranular corrosion have occurred in the collet housing of drives at several BWRs.

This type of. cracking could occur in a number of drives and if the cracks propagated until severance of the collet housing occurred, scram could be -

prevented in the affected rods. Limiting the period of operation with a potentially severed collet housing will assure that the reactor will not be operated with a large number of rods with failed collet housings.

Surveillance Requirements:

The weekly control rod exercise test serves as a periodic check against deterioration of the control rod system and also verifies the ability of the control rod drive to scram, since, if a rod can'be moved with drive pressure, it will scram because of higher pressure applied during scram.

The frequency of exercising the control rods under the conditions of three or more inoperable rods provides even further assurance of the reliability of the remaining control rods. l l

A limiting control rod pattern for RWE is a pattern which, due to unrestricted withdrawal of any single control rod, could result in violation of the MCPR Safety Limit. Specification 3.3.F. defines a limiting control rod pattern for RWE. During use of such patterns when both RBM channels are not operable, it is judged that testing of the RBM system prior to withdrawal of control rods to assure its operability will-assure that improper withdrawal does not occur. Reference NEDC-30474-P (Ref.17) for more information.

Limiting Conditions for Operation:

The RWM and the Rod Sequence Control System (RSCS) restrict withdrawals l and insertions of control rods to prespecified sequences. All patterns associated with these sequences have the characteristics that, assuming the worst single deviation f rom the sequence, the drop of any control rod from the fully inserted position to the position of the control rod drive would not cause the reactor to sustain a power excursion resulting in any .)

3.3.G.I. Rod Worttr Minimizer (RWM) (Continued)

In performing the function described above, the RWM and RSCS are not re-quired to impose any restrictions at core power levels in excess of 10% l of rated. Material in the cited references shows that it is impossible to reach 280 calories per gram in the event of a control rod drop occur-ring at power greater than 10%, regardless of the rod pattern. This is l true for all normal and abnormal patterns including those which maximize the individual control rod worth.

At power levels below 10% of rated, abnormal control rod patterns could l ,

produce rod worths high enough to be of concern relative to the 280 cal-  !

orie per gram rod drop limit. In this range of RWM and the RSCS con-strain the control rod sequences and patterns to those which involve only acceptable rod worths.

The RWM and the RSCS provide automatic supervision to assure that out l l of sequence control rods will not be withdrawn or inserted; i.e., it limits operator deviations from planned withdrawal sequences. They serve as a backup to procedural control of control rod sequences, which limit the maximum reactivity worth of control rods. In the event that the RWM is out of service, when required, a second licensed operator or l_

other qualified technical plant employee whose qualifications have been reviewed by the AEC can manually fulfill the control rod pattern conformance functions of this system.

The functions of the RWM and RSCS make it unnecessary to specify a license limit on rod worth to preclude unacceptable consequences in the event of a control rod drop. At low powers, below 10%, these devices force ad-herence to acceptable rod patterns. Above 10% of rated power, the con- ,

sequences of a rod drop event without RWM or RSCS are acceptable.

Power level for automatic cutout of the RSCS function is sensed by first stage turbine pressure. Power level for automatic cutout of the RWM function is sensed by feedwater and steam flow and is set to be consistent with the RSCS setting.

Surveillance Requirements:

Functional testing of the RWM prior to the start of control rod withdrawal at startup,-and prior to attaining 10% of rated thermal power during rod in-l sertion while shutting down, will ensure reliable operation and minimize the probability of the rod drop accident.

BASES FOR LIMITING CONDITIONS FOR OPERATION AND SURVEILLANCE RE0VIREMENTS 3.6.1. Jet Pumps (Continued)

A nozzle-riser system failure could also generate the coincident failure of a jet pump body; however, the converse is not true. The lack of any substantial stress in the jet pump body makes f ailure impossible without an initial nozzle riser system failure.

One of the acceptable procedures for jet pump surveillance, identified in NUREG/CR-3025, Reference 2, was adopted for Hatch Unit 1. The surveillance is performed to verify that neither of the following conditions occur:

(a) The Recirculation Pump Flow / Speed Ratio deviates by more than 5% from the normal range, or (b) The Jet Pump Loop Flow / Speed Ratio deviates by more than 5% from the normal range.

If either criterion is f ailed, then the procedure calls for comparing either the individual jet pump flow or individual jet pump dif fuser to lower plenum differential pressures to the criteria of the Limiting

) Conditions for Operation (LCO). If the LCO criteria are not satisfied

[ and pump speed is less than 60% of rated, it may be necessary to increase pump speed to above 60% of rated and repeat the measurements

{ before declaring a jet pump inoperable. In this case, it is

) recommended that close monitoring and increased recirculation pump

~

speed should be performed only if the criteria are exceeded by an amount to be determined from previous plant operating experience.

3.6.J. Recirculation System Operation with a single reactor coolant system recirculation pump.is allowed, provided that adjustments to the flow referenced scram and APRM rod block setpoints, MCPR cladding integrity Safety Limit, MCPR Operating Limit, and MAPLHGR limit are made. An evaluation of the performance of the ECCS with single-loop operation has been performed and determined to be acceptable, Reference 4. Based on this Reference, a f actor is applied to reduce the APLHGR limits during single-loop operation. To account for increased uncertainties in the total core flow and TIP readings when operating with a single recirculation loop, an increase is applied to the l MCPR cladding integrity Safety Limit and MCPR Operating Limit over the comparable two-loop values. The flow referenced simulated thermal power scram and rod block setpoints for single-recirculation-loop operation is reduced by the amount of maw, where m is the flow reference slope for the >

rod block monitor and aW is the largest dif f erence between two-loop an(

single-loop ef fective drive flow when the active loop indicated flow is the same. This adjustment is necessary to preserve the original relationship between the rod block and actual ef fective drive flow.

When restarting an idle pump, the discharge valve of the idle. loop is required to remain closed until the speed of the faster pump is below 50% of its rated speed to provide assurance that when going f rom one- to two-loop operations, excessive vibration of the jet pump risers will not occur.

l The possibility of experiencing limit cycle oscillations during single-loop l

operation is precluded by restricting the core flow to greater than or equal to 45% of rated core flow when core power is greater than the 80% rod line.

l This requirement is based on General Electric's recommendations contained in SIL 380, Revision 1, which defines the region where the limit cycle oscillations are more like!! to occur.

l BASES FOR LIMITING CONDITTONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS 3.11. FUEL R005 -

A. Average. Planar Linear Heat Generation Rate ( APLHGR)

This specification assures that the peak cladding temperature following the postulated design basis loss-of-coolant accident (LOCA) will not exceed the limit specified in 10 CFR 50.46 even considering the postulated ef fects of fuel pellet densification.

The peak cladding temperature following a postulated loss-of-coolant acci-dent is primarily a f unction of the average heat generation rate of all the rods of a fuel assembly at any axial location and is only dependent second-arily on the rod to rod power distribution within an assembly. Since ex-pected local variations in power distribution within a fuel assembly af fect the calculated peak clad temperature by less than i 20'F relative to the peak temperature for a typical fuel design, the limit on the average linear heat generation rate is sufficient to assure that calculated temperatures. ,

conform to 10 CFR 50.46. The limiting value for APLHGR is provided in the Core Operating Limits Report.

The calculational procedure used to establish the APLHGR limits is based on a LOCA analysis. The analysis was performed using General Electric (GE) 1 calculational models which are consistent with the requirements of Appendix K to 10 CFR 50. The LOCA analysis was performed utilizing the new improved calculational model, SAFER /GESTR-LOCA. The analysis demonstrated that loss-of-coolant concerns do not limit the operation of the fuel since margin to the 2200*F limit was demonstrated (Reference 9). Therefore, the ,

APLHGR limits are derixed to assure that the fuel thermal-mechanical l <

design criteria are met.

A flow dependent correction f actor is applied to the rated conditions APLHGR to assure that the 2200'F PCT limit is complied with during LOCA initiated from less than rated core flow. In addition, other power and flow dependent corrections are applied to the rated conditions APLHGR l limits to assure that the fuel thermal-mechanical design criteria are met during abnormal transients initiated f rom of f-rated conditions for two-loop and single-loop operation 3, References 2 and 8. For single-loop operation, a multiplicative factor is applied to the rated conditions A'/LHGR ',imit for all fuel bundles when core power exceeds a specified vaiue. The power and flow-dependent correction factors, and the limiting values for APLHGR for each fuel type used in a particular cycle are specified in the Core Operating Limits Report.

i BASES FOR LIMITING CONDITIONS FOR OPERATION AND SURVEILLANCE REQUIREMENTS y 3.11. B . Linrar Heat Generation Rate (LHGR)

This specification assures that the LHGR in any rod is less than the design linear heat generation if fuel pellet densification is postulated. For LHGR to be a limiting value below 25-percent rated thernal power, the ratio of peak LHGR to core average LHGR would have to be greater than 9.6, which is precluded by a considerable margin when employing any permissible control rod pattern.

C. Minimum Critical Power Ratio (MCPR)

'The required operating limit MCPR as specified in Specification 3.11.C is derived from the established fuel cladding integrity Safety Limit MCPR and an analysis of abnormal operational transients presented in Reference 1.

Various transient events will reduce the MCPR below the operating MCPR.

To assure that the fuel cladding integrity Safety Limit is not violated during anticipated abnormal operational transients, the'most limiting transients have been analyzed to determine which one results in the largest reduction in critical power ratio (A MCPR). Addition of the largest A MCPR to the Safety Limit MCPR gives the minimum operating limit MCPR to avoid violation of the Safety Limit should the most limiting transient occur.

The type of transients evaluated were loss of flow, increase in pressure and power, positive reactivity insertion, and coolant temperature decrease.

Details of how MCPR evaluations are performed, the methods used, and how the MCPR limit is adjusted for operation at less than rated power and flow conditions used for single-loop operation are given in Reference 1 and in the Core Operating Limits Report.

1 2.1 SAFETY LIMITS BASES I

J 2.0 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 operations and anticipated tran-sients. The fuel cladding integrity Safety Limit is set such that no fuel damage is calculated to occur if the 11init is not violated. Because fuel damage is not directly observable, a step-back approach is used to establish a Safety Limit such that the MCpR is not less than 1.07 for two-loop operation and 1.08 for single-loop operation. These limits represent a conservative margin relative to the conditions required to maintain fuel cladding integrity. The fuel cladding is one of the physical barriers which separate the radioactive materials from the environs. The integrity of this cladding barrier is related to its relative freedom from perforations or 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 Limiting Safety System Settings. While fission product migration from cladding perforation is just as measurable as that from use related cracking, the thermally caused cladding perforations signal a threshold beyond which still ,

greater thermal stresses may cause gross rather than incremental cladding  !

deterioration. Therefore, the fuel cladding Safety Limit is defined with a 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.

The evaluations which justify normal operation, abnormal transient, and

, accident analyses for two-loop operation are discussed in detail in Reference 1

1. Evaluation for single-loop operation demonstrates that two-loop transient and accident analyses are more limiting than single-loop, Reference 2.

2.1.1 THERMAL POWER (Low Pressure or Low Flow)

The use of the NRC-approved transition boiling correlation is not valid- l for all critical power calculations at pressures below 785 psig or core flows less than 10% of rated flow. Therefore, the fuel cladding integrity Safety Limit is established by other means. This is_done by establishing a limiting condition on core THERMAL POWER with the following basis. Since the pressure drop in the bypass region is essentially all elevation head, the core pressure drop at low power and flows will always be greater than 4.5 psi. Analyses show that with a bundle flow of 28 x 10' lbs/hr, bundle pressure drop is nearly independent of bundle power and has a value of 3.5 psi. Thus, the bundle flow with a 4.5 psi driving head will be greater than 28 x 10' lbs/hr. Full scale ATLAS test data taken at pressures from 14.7 psia to 800 psia indicate that the fuel assembly critical power at this flow is approximately 3.35 MWt. With the design peaking factors, this corresponds to ,

HATCH - UNIT 2 B 2-1 Proposed TS/0266q/006-77

li i

l SAFETY LIMITS BASES (Continued) a THERMAL POWER of more than 50% of RATED THERMAL POWER. Thus, a THERMAL POWER limit of 25% of RATED THERMAL POWER for reactor pressure below 785 psig is conservative.

I 2.1.2 THERMAL POWER (High Pressure and High Flow) i

.The fuel cladding integrity Safety Limit is set such that no fuel damage is calculated to occur if the limit is not violated. Since the parameters which result in fuel damage are not directly observable dur-ing reactor operation, the thermal and hydraulic conditions resulting in a departure from nucleate boiling have been used to mark the beginning of the region where fuel damage could occur. Although it is recognized that a departure from nucleate boiling would not necessarily result in damage to BWR fuel. rods, the critical power at which boiling 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 result in an uncertainty in the value of the critical power. Therefore, the fuel cladding integrity Safety Limit .is defined as the CPR in the limiting fuel assembly for which more than 99.9% of the fuel rods in the core are expected to avoid boiling transition considering the power distribution within the core and all uncertainties.

The'MCPR Safety Limit is determined using a model that combines all of l the uncertainties in operating parameters and the procedures used to calculate- i critical power. The probability of the occurrence of boiling transition is determined using an NRC-approved critical power correlation. Details of the fuel cladding integrity Safety Limit calculation are. presented in Reference 1.  ;

REACTIVITY CONTROL SYSTEMS.

BASES CONTROL RODS (Continued) than has been analyzed even though control rods with inoperable accumulators may still be inserted with normal drive water pressure. Operability of the accumulator ensures that there is a means available to insert the control rods even under the most unfavorable depressurization of the reactors.

Control rod coupling integrity is required to ensure compliance with the analysis of the rod drop accident in the FSAR. The overtravel position feature provides the only positive means of determining that a rod is properly coupled and therefore this check must be performed prior to achieving criticality after each refueling. The subsequent check is performed as a backup to the initial demonstration.

In order to ensure that the control rod patterns can be followed and therefore that other parameters are within their limits, the control rod-position indication system must be OPERABLE.

The control rod housing support restricts the outward movement of a control rod to less than 3 inches in the event of a housing failure.

The amount of rod reactivity which could be added by this small amount of rod withdrawal is less'than a normal withdrawal increment and will not contribute to any damage to the primary coolant system. The support is not required when there is no pressure to act as a driving force to rapidly eject a drive housing.

The required surveillance intervals are adequate to determine that the rods are OPERABLE and not so frequent as to cause excessive wear on the system components.

3/4.1.4 CONTROL R0D PROGRAM CONTROLS 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 be worth enough to cause the peak fuel enthalpy for any postulated control rod-accident to exceed 280 cal /gm. The specified sequences are characterized by homogeneous, scattered patterns of control rod withdrawal. When  !

THERMAL POWER is 2 10?; of RATED THERMAL POWER, there is no possible rod l

worth which, if dropped at the design rate of the velocity limiter, could result in a peak enthalpy of 280 cal /gm. Thus, requiring the RWM to be OPERABLE below 10% of RATED THERMAL POWER and the RSCS to be OPERABLE from 50?; control rod density to 10% of RATED THERMAL POWER provides adequate control.

BASES  !

l The specifications of this section assure '. hat the peak cladding ~l temperature following the postulated design basis loss of-coolant accident will not exceed the 2200 F limit specified in the Final Acceptance Criteria (FAC) issued in June 1971 considering the postulated effects of fuel pellet densification. These specifications also assure that fuel design margins are maintained during abnormal transients. f 3/4.2.1 AVERAGE PLANAR LINEAR HEAT GENERATION RATE 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. peak cladding temperature (PCT) fol'owing 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 dependent only secondarily on the rod-to-rod power distribution within an assembly. The peak clad temperature'is calculated assuming an LHGR for the highest powered rod l which is equal to the design LHGR for that fuel type.

The calculational procedure used to establish the APLHGR limits for l l Technical Specification 3/4.2.1 is based on a ' loss-of-coolant accident analysis. The analysis was performed using General Electric (GE) calculational models which are consistent with the requirements of Appendix K to 10 CFR 50. The Loss-of-Coolant Accident (LOCA) analysis was performed utilizing the new improved calculational model, SAFER /GESTR-LOCA.

The analysis demonstrated that loss-of-coolant concerns do not limit the operation of the fuel since margin to the 2200 F limit was demonstrated for all of these

-fuel types (Reference 4). Therefore, the APLHGR limits for the fuel types shown in the CORE OPERATING LIMITS REPORT are based on the fuel thermal-mechanical design criteria.

A flow dependent correction factor is applied to the rated conditions l APLHGR to assure that the 2200 F PCT limit is complied with during a LOCA initiated from less than rated core flow. In addition, other power and flow dependent corrections are applied to the rated conditions APLHGR limit to l assure that the fuel thermal-mechanical design criteria are preserved during abnormal transients initiated from off-rated conditions. For single-loop operation, a multiplicative factor is applied to the rated conditions APLHGR limit for all fuel bundles ihen core power exceeds a specified value. The power and flow-dependent correction factors and the limiting values for APLHGR for each fuel type used in a particular cycle are specified in the CORE OPERATING LIMITS REPORT.

3/4.2.3 MINIMUM CRITICAL POWER RATIO-The required operating limit MCPRs at' steady state operating conditions as specified in' Specification 3.2.3 are derived from the established fuel cladding integrity Safety Limit MCPR of 1.07 for two-loop operation and 1.08 for single-loop operation, and an analysis of abnormal operational trasients (Reference 1). 'For any abnormal operating transient analysis evaluation with l

- the' initial. condition of the reactor being at'the steady state operating limit (specified in the CORE OPERATING LIMITS REPORT), 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 as given in

. Specification 2.2'1. .

To assure that the fuel cladding integrity Safety Limits are not violated l during any anticipated abnormal operational transient, the~ trast limiting transients have been analyzed to determine which results in the largest reduction in CRITICAL POWER RATIO (CPR). The type.of transients evaluated were . loss of flow, increase in pressure and power, positive. reactivity insertion, and coolant temperature decrease.

Details of how evaluations are performed, the methods used,'and how the

' MCPR -limit is adjusted for operation at less than rated power and flow conditions are given in Reference 1 and in the CORE OPERATING LIMITS REPORTS.

3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1.1 RECIRCULATION SYSTEM Operation with a rea. ;olant recirculation loop inoperable is allowed, provided that adjustments to the flow referenced scram and APRM rod block setpoints, MCPR cladding integrity Safety Limit, MCPR Operating Limit, and MAPLHGR limit are made. An evaluation of the performance of the ECCS with single-loop operation has been performed and determined to be acceptable, Reference 1. The adjustments to the APLHGR and the MCPR limits that are required for single-loop operation are provided in the CORE OPERATING LIMITS REPORT. The flow referenced simulated thermal power setpoint for single-loop operation is reduced by the amount of MAW, where m is the flow reference slope for the rod block monitor and AW is the 11rgest difference between two-loop and single-loop effective drive flow when the active loop indicated flow is the same. This adjustment is necessary to preserve the original relationship between the scram trip and actual drive flow.

The possibility of experiencing limit cycle oscillations during single-loop operation is precluded by restricting the core flow to greater than or equal to 45% of rated when core thermal power is greater than the 80%

rod line. This requirement is based on General Electric's recommendations contained in SIL-380, Revision 1, which defines the region where the limit cycle oscillations are more likely to occur.

3/4.4.1.2 JET PUMPS An inoperable jet pump is not, in itself, a sufficient reason to declare a recirculation loop inoperable, but it does present a hazard in case of a design basis loss-of-Coolant Accident by increasing the blowdown area and eliminating the capability of reflooding the core; thus, the requirement for shutdown of the facility with a jet pump inoperable is necessary.

One of the acceptable procedures for jet pump failure surveillance identified in NUREG/CR-3052, Reference 2, was adopted for Hatch Unit 2. The surveillance is performed to verify that neither of the following conditions occur:

(a) The recirculation pump flow / speed ra:'o neviates by more than 5%

from the normal range, or (b) The jet pump loop flow / speed ratio deviates by more than 5% from tne normal range.

^

If either criterion is failed, then the procedure calls for comparing either the individual jet pump flows or the individual jet pump diffuser to lower plenum differential pressures to the criteria of the Limiting Conditions for Operation (LCO). If the LCO is not satisfied and pump speed is less than HATCH - UNIT 2 B 3/4 4-1 Proposed TS/0270q/006-77
