Changes To Final Safety Analysis Report Section 15.4 To Include Continuous Rod Nithdrawal Analysis In the Start-Up Range
M'
Subject:
Justification for changes to Final Safety Analysis Report (FSAR) to include continuous rod withdrawal analysis in the start-up range.
The requested changes to the FSAR are enclosed.
Technical Specification 2.2.1 item 1 under Bases for Limiting Safety .System Settings references the FSAR for an analysis of continuous rod withdrawal in the start-up range. This pertains to an analytical case beyond the licensing basis. The Nuclear Regulatory Commission has imposed similar wording on BWR utilities since the issue was first debated on the Hatch 2 docket.
In order to make sure the Technical Specifications are well supported by the FSAR, Niagara Mohawk requests that FSAR Section 15.4 be revised to include an analysis of continuous rod withdrawal in the start-up range. This revision described a special study previously docketed for Hatch 2, Fermi 2, and LaSalle.

Nine Mile Point Unit 2 FSAR 15.4.1.1..5 Radiological Consequences An evaluation of the radiological consequences was not made for this event since no radioactive material is released from the fuel.
15.4.1.2 Continuous Rod Withdrawal During Reactor Startup 15.4.1.2.1 Identification of Causes and Frequency Classification The probability of initial causes of errors for this event alone is considered low enough to warrant its being categorized as an infrequent incident. The probability of further development of this event is extremely low because it i s contingent upon the simultaneous failure o f two redundant systems, the RSCS and the RWM system concurrent with a high worth rod, out-of-sequence rod selection contrary to procedures, plus operator non-acknowledgement of continuous alarm annunciations prior to safety system actuation.
15.4.1.2.2 Sequence of Events and Systems Operation Se ence of Events Control rod withdrawal errors are not considered credible in the startup and low power ranges. The RSCS and RWM prevent the operator from selecting and withdrawing .an out-of-secruence control rod. A special analysis described in Section 15.4.1.3 shows that, even for the unlikely event where the R'IlN and RSCS fail to block the continuous withdrawal of an out-of-sequence rod, the licensing basis criterion for fuel failure is still satisfied.
Continuous control rod withdrawal errors during reactor startup are precluded by the RSCS. The RSCS prevents the withdrawal ~
of an out-of-sequence control rod in the 100-percent to 75-percent control rod density range and limits rod movement to the b'anked position mode of rod withdrawal from the 75-percent rod density to the preset power level. Since only in-sequence control rods can be withdrawn in the 100-percent to 75-percent control rod density and control rods are withdrawn in the banked position mode from the 75-percent control rod density point to the preset power level, there is no basis for the continuous control rod withdrawal error in the startup and low power range. The low power range is defined as zero power to the RSCS low power set point, i.e., 20 percent of rated core power. For RWE above low power set point see Section 15.4.2. The banked position mode of the RSCS is described in Reference 1.

~ V g gg*t T
Nine Mile Point Unit 2 FSAR Identification of 0 erator Actions No operator actions are required to preclude this event since the plant design as discussed above prevents its occurrence.
Effects of Sin le Failure and 0 erator Errors If any one of the operations involved the initial failure or error and is followed by another SEF or SOE, the necessary safety actions (e.g., rod blocks) are automatically taken prior to any limit violation. Refer to Appendix 15A for details.
15.4.1.2.3 Core and System Performance The performance of the RSCS and RWM prevent erroneous selection and withdrawal of an out-of-sequence control rod.
Thus, the core and system performance is not affected by such an operator error.
No mathematical models are involved in this event. The need for input parameters or initial conditions is not required as there are no results to report. Consideration of uncertainties is not appropriate.
15.4.1.2.4 Barrier Performance An evaluation of the barrier performance was not made for this event since there is no postulated set of circumstances for which this error could occur.
15.4.1.2.5 Radiological Consequences An evaluation of the radiological consequences is not required for this event since no radioactive material is released from the fuel.
15.4.1.3 Special Analysis The RSCS and RNM constraints on rod sequence will prevent the continuous withdrawal of an out-of-sequence rod. This analysis was performed to demonstrate that, even for the unlikely event= where an out-of-sequence control rod is withdrawn at the maximum allowable normal drive speed, the licensing basis criterion for fuel not be exceeded.

Nine Mile Point Unit 2 FSAR This analysis is extracted for Nine Mile Point 2 application from a generic study (Reference 7) previously docketed for Hatch 2, Fermi 2, and LaSalle. The analysis concludes that as a result of continuous withdrawal of an out-of-sequence rod in the start-up range, the reactor is shut down and peak power is limited to 21'/ of rated thermal power with the peak fuel enthalpy well below the licensing basis fuel failure threshold of 170 cal/gm. Therefore, evaluation of barrier performance and radiological consequences is not necessary.
15.4.2 Rod Withdrawal Error at Power 15.4.2.1 Identification of Causes and Frequency Classification 15.4.2.1.1 Identification of Causes While operating in the power range in a normal mode of operation the reactor operator makes a procedural error and continuously withdraws the maximum worth control rod until the rod block monitor (RBM) system inhibits further withdrawal.

iS Changes To Technical Specifications In The Area of Signal-To-Noise Ratio For Source Range Monitors
~ t I'
~
Subject:
Justification for changes to Technical Specifications in the area of signal-to-noise ratio for source range monitor (SRM).
The recent Technical Specifications allow the source count rate to be less than 3 counts per second (cps) for initial fuel loading and plant startup if the following conditions are met: the signal to noise ratio is greater than 2.0, and the signal is greater than 0.7 cps.
Niagara Mohawk requests that the signal to noise ratio be changed from 2.0 to 20 (twenty). The higher signal to noise ensures that the response from the SRM is proper with the lower count rate. The requested changes to Technical Specifications are enclosed.
The 20:1 signal to noise ratio was established by a statistical analysis in order to justify the lowering to the SRM down-scale setpoint of 0.7 cps. From this analysis, it was concluded that a signal to noise ratio of 20 is necessary for a count rate signal to trip at 0.7 cps in order to maintain a confidence level of greater than 95% for source count rate monitoring and a probability of better than 97 .7% for initiating rod b'lock.

22 PLANT SYSTEMS BASES SNUBBERS 3/4. 7. 5 (Continued) before that interval has elapsed may be used as a new reference point to deter-mine the next inspection. However, the results of such early inspections per-formed before the. or iginally required time interval has elapsed, nominal time less 25K, may not be used to lengthen the required inspection interval. Any inspection whose results require a shorter inspection interval will override the previous schedule.
Mhen the cause of the rejection of a snubber is clearly established and reme-died for that snubber and for any other snubbers that may be generically susceptible, and verified by inservice functional testing, that snubber may be exempted from'being counted as inoperable. Generically susceptible snubbers are those snubbers that are of a specific make or model and have the same design features directly related to rejection of the snubber by visual inspection or are similarly located or exposed to the same environmental conditions, such as temperature, radiation, and vibration.
Nen a snubber is found inoperable, an engineering, evaluation is performed, in addition to the determination of the snubber mode of failure, in order to determine if any safety-related component or system has been adversly affected by the inoperability of the snubber. The engineering evaluation shall determine whether or not the snubber mode of failure has imparted a significant effect or degradation on the supported component or system.
The service life of a snubber is evaluated via manufacturer input and informa-tion through consider ation of the snubber service conditions and associated installation and maintenance 'records, i. e., newly installed snubber, seal replaced, spring replaced, in high-radiation area, in high-temperature area, etc. The requirement to monitor the snubber service life is included to ensure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions. These records will provide statistical bases for future consideration of snubber service life. The requirements for the maintenance of records .and the snubber service life review are not intended to affect plant operation.

SUBJECT:
Justification for the changes to Technical Specification and Final Safety Analysis Report in the area of liquid effluent sampling for auxiliary boiler pump seal cooling service water discharge.
The requested changes to Technical Specification and Final Safety Analysis Report are enclosed.
Service water is supplied to the heat exchangers for cooling the closed loop seal water to the auxiliary boiler recirculating pump. The service water discharge from the heat exchangers is routed to the auxiliary boiler building floor drains which is directed to the radwaste system evaporator.
During system testing, it was found that the quantity of the service water returned from the heat exchangers places unnecessary burden on the radwaste evaporator. The service water return was re'-routed to the equipment drain located in the diesel fire pump cubicle. This drain is discharged to the fire pump intake shaft. Therefore, Niagara Mohawk proposes to change the Technical Specification and Final Safety Analysis Report to include periodic local grab samples of the service water discharge for radiological analysis.
Niagara Mohawk also recommends change to the Safety Evaluation Report, page 11-10, from "All release points are continuously monitored for radioactivity before discharge" to "All release points are either continuously monitored or routinely sampled for radioactivity during discharge."

Tritium in the plant areas is determined on the basis of representative grab samples collected from the effluent points or ventilation exhaust ducts. Grab samples are obtained from locations indicated in Table 11 '-2. Samples are analyzed in the health physics laboratory, or by contracted 1aboratori es.
11.5.3 Effluent Monitoring and Sampling All potentially radioactive gaseous and liquid effluent discharge paths are either continuously monitored or routinely sampled for radiation level during discharge (Section 11.5.2). Solid waste shipping containers are monitored with gamma sensitive portable survey instruments. The following gaseous effluent paths are sampled and monitored:
- 1. Plant main stack exhaust.
- 2. Combined radwaste/reactor building ventilation exhaust.
The fol lowing monitored:
liquid ef fluent paths are sampled and
- 1. Liquid radwaste system effluent.
- 2. Circulating water system cooling tower blowdown line.
- 3. Service water system discharge.
All monitor ranges are listed in Table 11.5-1.
An isotopic analysis is performed periodically 'on samples obtained from each liquid effluent release path to verify the adequacy of effluent processing to meet the discharge limits to unrestricted areas.
This effluent monitoring and sampling program is comprehensive and provides the information for the effluent measuring and reporting programs required by 10CFR50 Section 36a, Appendix A, General Design Criterion 64, and Appendix I and Regulatory Guide 1.21 in semiannual reports to the NRC.
The frequency of the periodic sampling and analysis described in the technical specifications is a minimum and is increased if effluent levels approach technical speci-fication limits. Isotopic content of gaseous effluents is continuously monitored by offline monitors. All

The requested change is enclosed.
The current Technical Specification 6.9.1.8 (Semi-annual Radioactive Effluent Release Report) requires the use of real-time meteorology in the calculation of radiation dose assessment.
Niagara Mohawk requests the deletion of the requirement in Technical Specification 6.9.1.8 of using real-time meteorology. The Offsite Dose Calculational Manual describes the procedures for radiation dose assessment. We request the option to use average meteorology or real-time meteorology, The guidance for Radiological Effluent Technical Specifications given in NUREG-0133 recommends the use of average meteorology rather than real-time meteorology. The use of real-time meteorology is necessary in the event of specific, short time, high release situations.

Since the calculated maximum decay ratio is less than that of some of the operating plants (for example, Peach Bottom Unit 3 has the maximum decay ratio of 0.93), the staff concludes that NMP-2 core design stability is acceptable for cycle 1 on the condition that the Technical Specifications include appropriate limiting conditions for operation and surveillance requirements to address the concerns stated in SIL-380 and to avoid operation in regions of thermal-hydraulic instability. Also, in order to provide additional margin for stability, normal operation in natural circulation is prohibited."
In a letter from C. O. Thomas (NRC) to H. C. Pfefferlen (GE), "Acceptance for Referencing of Licensing Topical Report NEDE-24011, Rev. 6, Amendment 8, Thermal Hydraulic Stability Amendment to GESTAR II," dated 4/24/85, the Nuclear Regulatory Commission Safety Evaluation report states:
"For GE reloads using Table 1 fuels in plants which have not yet implemented improved stability monitoring Technical Specifications the current practice of using the methods of NEDE-22277-P-1 to calculate a cycle specific decay ratio must be continued. This reload will be considered acceptable if the decay ratio is shown to be less than 0.80 for all possible operating conditions."
This statement is applied to all General Electric-designed fuels contained in Table 1 of the referenced Safety Evaluation Report which includes initial core fuel for Nine Mile Point Unit 2. Therefore, the conclusion of the Safety Evaluation Report is applicable to the Nine Mile Point Unit 2 initial core load, and no stability Technical Specifications (for two loop operation) are required, since the decay ratio is less than 0.8 for the initial core.

54B 3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4. 1 RECIRCULATION SYSTEM The impact of single recirculation loop operation upon plant safety is assessed and shows that single-loop operation is permitted if the MCPR fuel cladding safety limit is increased as noted by Specification 2.1.2, APRM scram and con-trol rod block setpoints are adjusted as noted in Tables 2.2.1-1 and 3.3.6"2, respectively, MAPLHGR limits are decreased by the factor. given in Specifica-tion.3.2P,aad NCPR operating limits are adjusted per Section 3/4.2.3.
Additionally, surveillanc'e on the volumetric flow rate of the operating re-circulation loop is imposed to exclude the possibility of excessive core internals vibration. The surveillance on differential temperatures below 30K" THERMAL POWER or 50K" rated recirculation loop flow is to mitigate the undue thermal stress on vessel nozzles, recirculation pump and vessel bottom head during the extended operation of the single recirculation loop mode.
The objective of GE BWR plant and fuel design is to provide stable operation with margin over the normal operating domain. However, at the high-.power/
low-flow corner of the operating domain, a small probability of limit cycle neutron flux oscillations exists, depending on combinations of operating conditions (e.g., rod pattern, power shape). To provide assurance that neutron flux limit cycle oscillations are detected and suppressed, APRM and LPRM neutron flux noise levels should be monitored while operating in this region, Stability tests at operating BWRs were reviewed to determine a generic region of the power/flow map in which surveillance of neutron flux noise levels should be performed. A conservative decay ratio of 0. 6 was chosen as the basis for
'determining the generic region for surveillance to account for the plant-to-plant variability of decay ratio with core and fuel designs. This generic region has been determined to correspond to a core flow of less than or equal to 45X of rated core flow and a THERMAL POWER Figure 3.4.1. 1-1. < SV8{js'n We NW~{i2d one Og Plant-specific calculations can be performed to determine an applicable region for monitoring neutron flux noise levels. In this case, the degree of conser-vatism can be reduced since plant-to-plant variability would be eliminated. In this case, adequate margin will be assured by monitoring the region which has a deca ratio reater tha or

The final values are determined during startup testing based upon the threshold THERMAL POWER and recirculation loop flow which will sweep the cold water from the vessel bottom head, preventing stratification.

fg 54C The value of 0.8 provides margin to account for calculational uncertainties in predicting the 1.0 threshold for instability. It has been determined for NMP-2 that a decay ratio of less than 0.8 exists for all conditions involving two recirculation loop operation. Consequently monitoring for instability during two recirculation loop operation is not required.

Neutron flux noise levels which signifi-cantly bound these values are considered in the thermal/mechanical design of GE BWR fuel and are found to be of negligible consequence. In ad"ition, sta-bility tests at operating BWRs have demonstrated that when stability-related neutron flux limit cycle oscillations occur, they result in peak-to-peak neutron flux limit cycles of 5'o 10 times the typical values. Therefore, actions taken to reduce neutron flux noise levels exceeding three times the typical value are sufficient to ensure early detection of limit cycle neutron flux oscillations.
An inoperable jet pump is not, in itself, a sufficient reason to declare a recirculation loop inoperable, but it does, in case of a design"basis accident, increase the blowdown area and reduce the capability of ref looding the core; thus, the requirement for shutting down the facility when a jet pump is in-operable. Jet pump failure can be detected by monitoring jet pump performance on a prescribed schedule for significant degradation.
Recirculation loop flow mismatch limits are in compliance with -the ECCS LOCA analysis design criteria for two recirculation loop operation. The limits will ensure an adequate core flow coastdown from either recirculation loop after a LOCA. In the case where the mismatch limits cannot be maintained during two loop operation, continued operation is permitted in a single recirculation loop mode.
In order to prevent undue stress on the vessel nozzles and bottom head region, the recirculation loop temperatures shall be within 50'F of each other before startup of an idle loop. The loop temperature must also be within 50'F of the reactor pressure vessel coolant temperature to prevent thermal shock to the NINE MILE POINT - UNIT 2 B3/4 4"2

Typically, neutron flux noise levels show a gradual increase in absolute magnitude as core flow is increased (constant control rod pattern).
Therefore, the baseline neutron flux noise level obtained at a specified core flow can be applied over a range of core flows. Initial baseline data should be taken near the minimum power/flow condition where surveillance is required as determined in Specification 4.4.1.1.5.
Baseline data taken at this condition can be applied to the entire region of surveillance since the'aseline values will be lower (and therefore conservative) at the lower power/flow condition. Since baseline noise levels do not vary significantly during a cycle, the baseline data is only required once per cycle.

75 CHANGES TO FINAL SAFETY ANALYSIS REPORT TABLE 6.2-56 IN THE AREA OF CONTAINMENT ISOLATION SIGNAL
76
Subject:
Changes to Final Safety Analysis Report Table 6.2-56 in the area of Containment Isolation Signal.
As requested by Ms. M. Haughey, Niagara Mohawk will revise Table 6.2-56 of the Final Safety Analysis Report.
Table 6.2-56, "Containment Isolation Provisions for Fluid Lines," lists the containment isolation valves and their respective containment isolation signals'everal valves on the table also receive system actuation signals, and these are also listed. Technical Specification Table 3.6.3-1, "Primary Containment Isolation Valve," lists only containment isolation signals and therefore, does not coincide with the Final Safety Analysis Report.
The attached shows the change to Table 6.2-56 of the Final Safety Analysis Report which differentiates between system actuation and containment isolation signal to valves:
2CSH*MOV ill 2RHS*MOV 33A, 8 2NCS*MOV 112 These changes will be incorporated in a subsequent amendment to the Final Safety Analysis Report.

- 12. Manual Scram NA
- 5. Main Steam Line Isolation Valve - Closure The main steam line isolation valve (MSIV) closure trip was provided to limit the amount of fission product release for certain postulated events. The MSIVs are closed automatically from measured parameters such as high steam flow, high steam line radiation, low reactor water level, h>g earn tunnel temperature, and low steam line pressure. The MSIV's closure scram anticipates the pressure and flux transients that could follow MSIV closure and thereby protects reactor vessel pressure and fuel thermal/hydraulic Safety Limits.
- 6. Main Steam Line Radiation - Hi h The main steam line radiation detectors are provided to detect a gross failure of the fuel cladding. When the high radiation is detected, a trip is initiated to reduce the continued failure of fuel cladding. At the same time the main steam line isolation valves are closed to limit the release of fission products.
- 7. Dr ell Pressure - Hi h High pressure in the drywell could indicate a break in the primary pressure boundary systems. The reactor is tripped in order to minimize the possibility of fuel damage and reduce the amount of energy being added to the coolant.
- 8. Scram Dischar e Volume Water Level - Hi h The scram discharge volume receives the water displaced by the motion of the control rod drive pistons during a reactor scram. Should this volume up to a point where there is insufficient volume to accept the displaced water fill at pressures below 65 psig, control rod insertion would be hindered. The reactor is therefore tripped when the water level has reached a point high enough to indicate that it is indeed filling up, but the volume is still great enough to accommodate the water from the movement of the rods at pressur QW below'65 psig when they are tripped. The Trip Setpoint for each scram discharge volume is equivalent to a contained volume of approximately~ allons of water. This corresponds to a level indicating switch reading of-46-.7-inches above an instrument zero level of elevation 263 feet 10 inches. 43,+
- 10. Turbine Control Valve Fast Closure Tri Oil Pressure - Low The turbine control valve fast closure trip anticipates the pressure, neutron flux, and heat flux increase that could result from fast closure of the turbine control valves due to load rejection with or without coincident failure of the turbine bypass valves. The reactor protection system initiates a trip when fast closure of the control valves is initiated by the fast-acting solenoid valves and in less than 30 milliseconds after the start of control valve fast closure. This is achieved by the action of the fast-acting solenoid valves in rapidly reducing hydraulic trip oil pressure at the main turbine control valve actuator disc dump valves. This loss of pressure is sensed by pressure switches whose contacts form the one-out-of-two-twice logic input to the reactor protec-tion system. This trip setting, a slower closure time, and a different valve characteristic from that of the turbine stop valve, combine to produce transients which are very similar to that for the stop valve. .Relevant transient analyses are discussed in Section 15.2.2 of the Final Safety Analysis Report.
- 11. Reactor Mode Switch Shutdown Position The reactor mode switch Shutdown position provides additional manual reactor trip capability.
- 12. Manual Scram The manual scram pushbutton switches provide a diverse means for initiating a reactor shutdown (scram) to the automatic protective instrumentation channels and provides manual reactor trip capability.

Justification for deletion of items 2.h, 2.i, and 2.j from Plant Systems Actuation Instrumentation Tables 3.3.9-1, 3.3.9-2, and 4.3.9.1-1 in the Technical Specifications.
Niagara Mohawk requests the deletion to items 2.h, 2.i, and 2.j from Plant Systems Actuation Instrumentation Tables 3.3.9-1, 3.3.9-2, and 4.3.9-1 in the Technical Specifications because these parameters do not indicate the operability of the service water system. The parameters being deleted from these tables are associated with the control room chiller subsystem which is addressed in Limiting Conditions For Operation (LCO) 3.7.3, single asterisk footnote. The deleted parameters did not assure operability of the chiller subsystem by themselves. They are only three of the numerous parameters and components monitored by the operators to assure operability of the chi llers and compliance with LCO 3.7.3.

For a particular measurement system, which may include radiochemical separation:
4.66 sb LLD ED V-2. 22x106 Y.exp(-A4t)
Where:
LLD = the before-the-fact lower limit of detection (microcurie per unit mass or volume),
sb = the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (counts per minute),
= the counting efficiency (counts per disintegration),
= the sample size (units of mass or volume),
2.22x106 = the number of disintegrations per minute per microcurie,
= the fractional radiochemical yield, when applicable,
'= the radioactive decay constant for the particular radio-nuclide (sec-~), and
= the elapsed time between the midpoint of sample collection and the time of counting (seconds).
Typical values of E, V, Y, and ht should be used in the calculation.
It should be recognized that the LLD is defined as a before-the-fact limit representing the capability of a measurement system and not as an after-the-fact limit for a particular measurement.
(b) A batch release is the discharge of liquid wastes of a discrete volume.

131 REACTIVITY CONTROL SYSTEMS BASES CONTROL RODS (Continued}
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 before achieving criticality after
-completing CORE ALTERATIONS that could have affected the control rod coupling integrity. 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 indica-tion system must be OPERABLE.
The control rod housing support restricts the outward movement of a control rod to less than 6 inches in the event of a housing failure. The amount of rod reactivity that could be added by this small amount of rod withdrawal is less than a normal withdrawal increment and will not contribute 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 yet limited in frequency to avoid causing excessive wear on the system components.
3/4. 1.4 CONTROL ROD PROGRAM CONTROLS Control rod withdrawal and insertion sequences are established to assure that the maximum in-sequence individual control rod or control rod segments that are withdrawn at any time during the fuel cycle could not be worth enough to result in a peak fuel enthalpy greater than 280 cal/gm in the event of a control rod drop accident. The specified sequences are characterized by homogeneous, scattered patterns of control rod withdrawal. When THERMAL POWER is greater than 20K of RATED THERMAL, POWER, there is no possible rod 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 RSCS and RWM to be OPERABLE when THERMAL POWER is less than or equal to 20K of RATED THERMAL POWER provides adequate control.
The RSCS and RWM provide automatic supervision to assure that out-of-sequence rods will not be withdrawn or inserted.
The analysis of the rod drop accident is presented in Section 15.4 of the FSAR the techniques of the analysis are presented in a topical report (Ref-

3/4. 1.5 STANDBY LI UID CONTROL SYSTEM The standby liquid control system provides a backup capability for bringing the reactor from full power to a cold, xenon-free shutdown, assuming that the withdrawn control rods remain fixed in the rated power pattern. To meet this objective, it is necessary to inject a quantity of boron which produces a concen-tration of 660 ppm in the reactor core and other piping systems connected to the reactor vessel. To allow for potential leakage and imperfect mixing, this con-centration is increased by 20K. The required concentration is achieved by having a minimum available quantity of 4418 gallons of sodium-pentaborate solution con-taining a minimum of 5500 lb of sodium-pentaborate. This quantity of solution is' net amount which is above the pump suction, thus allowing for the portion that cannot be injected. The minimum pumping rate of 41.2 gpm per pump provides

negative reactivity insertion rate over the permissible penetaborate solution
~ ~ ~ ~
olume range, which adequately compensates for the positive reactivity effects
~ ~
from temperature and xenon during shutdown. The temperature requirement is
~ ~
necessary to ensure that the sodium pentaborate remains in solution.
~ ~ ~
With redundant pumps and explosive injection valves and with a highly reliable control rod scram system, operation of the reactor is permitted to continue for short periods of time when the system is inoperable or for longer periods of time when one of the redundant components is inoperable.
Surveillance requirements are established on a frequency that assures a high reliability of the system. Once the solution is established, boron concen-tration will not vary unless more boron or water is added; thus a check on the temperature and volume once every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> assures that the solution is available for use.
Replacement of the explosive charges in the valves at regular i.ntervals will assure that these valves will not fail because of deterioration of the charges.

3/4.2. 1 AVERAGE PLANAR LINEAR HEAT GENERATION RATE 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 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 which is equal to or less than the design LHGR corrected for densification. This LHGR times 1.02 is used in the heatup code along with the exposure-dependent steady-state gap conductance and rod-to-rod local peaking factor. 1-he-Teehni~-Speci+~he WVERAG~LANAR-LINEAR-HEAT-GENERATIeN-RA-FE-(APLHGR) mthe-LHBR-o fthe-highest

134 INSTRUMENTATION BASES 3/4. 3. 4 RECIRCULATION PUMP TRIP ACTUATION INSTRUMENTATION The anticipated transient without scram (ATMS) recirculation pump trip system provides a means of limiting the consequences of the unlikely occurrence of a failure to scram during an antic'ipated transient. The response of the plant to this postulated event falls within the envelope of study events in General
.Electric Company Topical Report NED0-10349, dated March 1971, NED0-24222, dated December 1979; and Section 15.8 of the FSAR.
The end-of-cycle recirculation pump trip (EOC-RPT) system is an essential safety supplement to the reactor trip. The purpose of the EOC-RPT is to recover the loss of thermal margin which occurs at the end of -cycle. The physical phenomenon involved is that the void reactivity feedback from a pressurization transient can add positive reactivity to the reactor system at a faster rate than the control rods add negative scram reactivity. Each EOC-RPT system reps o h recirculation pumps., reducing coolant flow in order to reduce the void collapse in the core during two of the most limiting pressurization events. The two events for which the EOC-RPT protective feature will function are closure of the turbine stop valves and fast closure of the turbine control valves.
A fast closure sensor from each of two turbine control valves provides input to the EOC-RPT system; a fast closure sensor from each of the othe", two turbine control valves provides input to the second EOC-RPT system. Similarly, a position switch for each of two turbine stop valves provides input to one EOC-RPT system; a position switch from each of the other two stop valves provides input to the other EOC-RPT system. For each EOC-RPT system, the sensor relay contacts are arranged to form a 2-out-of-2 logic for the fast
.closure of turbine control valves and a 2-out-of-2 logic for the turbine stop valves. The operation of either logic will actuate the EOC-RPT system and trip both recirculation pumps.
I Each EOC-RPT system may be manually bypassed by use of a switch which is administratively controlled by procedures. The manual bypasses and the auto-matic Operating Bypass at less than 30K of RATED THERMAL POWER are annunciated in the control room.
The EOC-RPT system response time is the time assumed in the analysis between initiation of valve motion and complete suppression of the electric arc, i. e.,
190 milliseconds. Included in this time are:. the time from initial valve movement to reaching the Trip Setpoint, the response time of the sensor, the response time of the system logic, and the time alloted for breaker arc supression; Operation with a trip set less conservative than its Trip Setpoint but within its specified Allowable Value is acceptable on the basis that the difference NINE MILE POINT - UNIT 2 B3/4 3-3
135 CONTAINMENT SYSTEMS BASES PRIMARY CONTAINMENT 3/4.6.1.4 PRIMARY CONTAINMENT STRUCTURAL INTEGRITY This limitation ensures that the structural integrity of the containment will be maintained comparable to the original design standards for the life of the unit. Structural integrity is required to ensure that the containment will withstand the design pressure of 45 psig in the event of a loss-of-coolant acci-dent (LOCA). A visual inspection in conjunction with Type A leakage tests is sufficient to demonstrate this capability.
3/4.6. 1.5 DRYWELL AND SUPPRESSION CHAMBER INTERNAL PRESSURE The limitations on drywell and suppression chamber internal pressure ensure that the containment peak pressure of 39.75 psig does not exceed the design pressure of 45.0 psig during LOCA conditions or that the external pressure differential does not exceed the design maximum external pressure differential of 4.7 psi. The limit of 14.2 to ~-psia for initial positive containment pressure will limit the total pressure to 39.75 psig, which is less than the design pressure and is consistent with the safety analysis.
3/4.6.1.6 DRYWELL AVERAGE AIR TEMPERATURE i~,As The limitation on drywell average air temperature ensur es that the containment peak air temperature does not exceed the design temperature of 340'F during steam line break conditions and is consistent with the safety analysis.
In addition, the maximum drywell average air temperature is also the limiting initial condition used to determine the maximum negative differential pressure acting on the drywell and suppression chamber following inadvertent actuation of the containment sprays.

The suppression pool water provides the heat sink for the reactor coolant sys-tems energy release following a postulated rupture of the system. The suppres-sion pool water volume must absorb the associated decay and structural sensible heat released during reactor coolant system blowdown from 1040 psig. Because all of the gases in the drywell are purged into the suppression pool air space during a LOCA, the pressure of the liquid must not exceed 45 psig, the suppres-
~
sion chamber maximum pressure..'he design volume of the suppression chamber (water and air).was obtained by considering that the total volume of reactor coolant is discharged to the suppression chamber and that the drywell volume
.is purged to the suppression chamber.
Using the minimum or maximum water volumes given in this specification, con-tainment pressure during the design-basis accident is approximately 40 psig, which is below the design pres'sure of 45 psig. Maximum water volume of 154,794 cubic feet results in a downcomer submergence of ll feet 0 inch, and the minimum volume of 145,495 cubic feet results in a submergence approximately 18 inches less. The majority 'of the Bodega Bay tests were run with a submerged length of 4 feet and with complete condensation. Thus, with respect to the downcomer submergence, this specification is adequate. The maximum temperature at the end of the blowdown tested during the Humboldt Bay and Bodega Bay tests was 170 F, and this is conservatively taken to be the limit for complete con-densation of the reactor coolant, although condensation would occur for temperatures above 170'F.

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 rem or less whole body, or its equivalent. This limitation is consistent with the requirements of GOC 19 of Appendix A to 10 CFR 50.
3/4.7.4 REACTOR CORE ISOLATION COOLING SYSTEM
. The reactor core isolation cooling (RCIC) system is provided 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 requiring actuation of any of the emergency core cooling system (ECCS) equipment. The RCIC system is conservatively required to be OPERABLE whenever reactor pressure exceeds 150 psig. This pressure is substantially below that for which the RCIC system can provide adequate core cooling for events requiring the RCIC system.
The RCIC system specifications are applicable during OPERATIONAL CONOITIONS 1, 2, and 3, when reactor vessel pressure exceeds 150 psig because RCIC is the pri-mary non-ECCS source of emergency core cooling when the reactor is pressurized.

MEMBERS OF THE PUBLIC resulting from the plant operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR 50 and thereby supplements the Radiological Effluent Monitoring Program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring, Revision 1, November 1979. The initially specified monitoring program will be effective for at least the first 3 years of commercial operation. After this period, program changes may be ini" tiated based on operational experience.

The LLDs required by Table~1~ re considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as a before-the-fact limit representing the capability of a measurement system and not as an after the-fact limit for a particular measurement.
Detailed discussion of the LLD, and other detection limits, can be found in L. A. Currie, "Lower Limit of Detection: Definition and Elaboration of a Proposed Position for Radiological Effluent and Environmental Measurements,"

155 INSTRUMENTATION BASES 3/4.3.4 RECIRCULATION PUMP TRIP ACTUATION INSTRUMENTATION The anticipated transient without scram (ATMS) recirculation pump trip system provides a means of limiting the consequences of the unlikely occurrence of a failure to scram during an anticipated transient. The response of the plant to this postulated event falls within the envelope of study events in General
.Electric Company Topical Report NED0-10349, dated March 1971, NED0-24222, dated December 1979; and Section 15.8 of the FSAR.
The end-of-cycle recirculation pump trip (EOC-RPT) system is an essential safety supplement to the reactor trip. The purpose of the EOC-RPT is to recover the loss of thermal margin which occurs at the,end of cycle. The physical phenomenon involved is that the void reactivity feedback from a pressurization transient can add positive reactivity to the reactor system at a faster rate than the control rods add negative scram reactivity. Each EOC-RPT system trips both recirculation pumps., reducing coolant flow in order to reduce the void collapse in the core during two of the most limiting pressurization events. The two events for which the EOC-RPT protective feature will function are closure of the turbine stop valves and fast closure of the turbine control valves.
A fast closure sensor from each of two turbine control valves provides input to the EOC-RPT system; a fast closure sensor from each of the other two turbine control valves provides input to the second EOC-RPT system. Similarly, a position switch for each of two turbine stop valves provides input to one EOC-RPT system;. a position switch from each of the other two stop valves provides input to the other EOC-RPT system. For each EOC-RPT system, the sensor relay contacts are arranged to form a 2-out-of-2 logic for the fast
.closure of turbine control valves and a 2-out-of-2 logic for the turbine stop valves. The operation of either logic will actuate the EOC-RPT system and trip both recirculation pumps.
t Each EOC-RPT system may be manually bypassed by use of a switch which is administratively controlled by procedures. The manual bypasses and the auto-matic Operating Bypass at less than 30K of RATED THERMAL POMER are annunciated in the control room.
The EOC-RPT system response time is the time assumed in the analysis between initiation of valve motion and complete suppression of the electric arc, i.e.,
190 milliseconds. Included in this time are: the time from initial valve movement to reaching the Trip Setpoint, the response time of the sensor, the response time of the system logic, and the time alloted for breaker arc supression.

3/4.3.6 CONTROL ROD BLOCK INSTRUMENTATION The control rod block functions are provided consistent with the requirements of the specifications in Section 3/4. 1.4, Control Rod Program Controls, and Section 3/4.2, Power Distribution Limits. The trip logic is arranged so that a trip in any one of the inputs will result in a control rod block.
Operation with a trip set less conservative than its Trip Setpoint but within its specified Allowable Value is acceptable on the basis that the. difference between each Trip Setpoint and the Allowable Value is an allowance for instru-ment drift specifically allocated for each trip in the safety analyses. The Trip Setpoint and Allowable Value also contain additional margin for instrument accuracy and calibration capability. The setpoint is referenced to a scram discharge volume instrument zero level at elevation 263 feet 10 inches.

This capability is consistent with 10 CFR 50, Appen-dix A, General Design Criteria (GDC) 19, 41, 60, 61, 63, and 64.

157 REACTOR COOLANT SYSTEM BASES 3/4.4.6 PRESSURE/TEMPERATURE LIMITS All components in the reactor coolant system are designed to withstand the effects of cyclic loads from temperature and pressure changes in the system.
These cyclic loads are introduced by normal load transients, reactor trips, and startup and shutdown operations. The various categories of load cycles used for design purposes are provided in Section 3.9 of the FSAR. During startup and shutdown, the rates of temperature and pressure changes are limited so that the maximum specified heatup and cooldown rates are consistent with the design assumptions and satisfy the stress limits for cyclic operation.
The operating limit curves of Figures 3.4.6.1-1, 3.4.6.1-2, and 3.4.6.1-3 are derived from the fracture toughness requirements of 10 CFR 50, Appendix G, and ASME Code Section III, Appendix G. The curves are based on the RTNDT and stress intensity factor information for the reactor vessel components. Fracture toughness limits and the basis for compliance are more fully discussed in FSAR Subsection 5.3. 1.5, "Fracture Toughness."
The reactor vessel materials have been tested to determine their initial RTNDT. The results of these tests are shown in Bases Table B3/4.4.6-1. Reactor operation and resultant fast neutron, E greater than 1 MeV, irradiation will cause an increase in the RTNDT. Therefore, an adjusted reference temperature, based upon the fluence, phosphorus content, and copper content of the material in question, can be predicted using Bases Figure B3/4.4.6-1 and the recommenda-tions of RG 1.99, Revision 1, "Effects of Residual Elements on Predicted Radiation Damage to Reactor Vessel Materials."
-The actual shrift in RTNDT of the vessel material will be established periodi-cally during operation by removing and evaluating irradiated specimens in-stalled near the inside wall of the reactor vessel in the. core area~Since the neutron spectra at the specimens and vessel inside radius are essentially identical@+"(he irradiated specimens can be used with confidence in predicting reactor vessel material transition temperature shift. The operating limit curves of Figures 3.4.6. 1-1, 3.4.6. 1-2, and 3.4.6.1-3 shall be adjusted, as required, on the basis of the specimen data and recommendations of RG 1.99, Revision 1. Data determined from specimens removed at the end of the first cycle will be used to adjust the fluence of Bases Figure B3/4.4.6-1.
The pressure-temperature limit lines shown in Figures 3.4.6.1-1 and 3.4.6. 1-3, for inservice hydrostatic testing and leak testing and for reactor criticality have been provided to assure compliance with the minimum temperature requirements of Appendix G to 10 CFR 50 for reactor criticality and for inservice leak and hydrostatic testing.
The number of reactor vessel irradiation surveillance capsules and the frequen-I cies for removing and testing the specimens in these capsules are provided in Table 4.4.6. 1.3-1 to assure compliance with the requirements of Appendix H to 10 CFR 50.
