d 3/4.1 REACTIVITY CONTROL SYSTEMS BASES 3/4.1.1 SHUTDOWN MARGIN A sufficient SHUTDOWN MARGIN ensures that (1) the reactor can be made subcritical from all operating conditions, (2) the reactivity transients associated with postulated accident conditions are controllable within acceptable limits, and (3) the reactor will be maintained sufficiently subcritical to preclude inadvertent criticality in the shutdown condition.

Since core reactivity values will vary through core life as a function of fuel depletion and poison burnup, the demonstration of SHUTDOWN MARGIN will be performed in the cold xenon-free condition and shall show the core to be subcritical by at least R + 0.28% aK or R + 0.38%aK, as appropriate.

The value of R in units of %4K is the difference between the calculated value of maximum core reactivity during the operating cycle and the calculated beginning-of-life core reactivity. The value of R must be positive or zero and must be datermined for each fuel loading cycle.

Satisfaction of this limitation can be best demonstrated at the time of fuel loading but the margin must be determined anytime a control rod is incapable of insertion. This reactivity characteristic has been a basic assumption in the analysis of plant performance.

Two different values are supplied in the Limiting Condition for Operation to provide for the different methods of demonstration of the SHUTDOWN MARGIN. The nighest worth rod may be determined analytically or by test. The SHUTDOWN MARGIN is demonstrated by an insequence control rod withdrawal at the beginning of life fuel cycle and, if necessary, at any future time in the cycle if the first demonstration indicates that the margin could be reduced as a function of exposure. Observation of subcriticality in this condition assuret subcriticality with.the most reactive control rod fully witndrawn.

3/4.1.2 REACTIVITY ANOMALIES Since the SHUTDOWN MARGIN requirement for the reactor is small, a careful check on actual conditions to the predicted conditions is necessary, and the changes in reactivity can be inferred from these comparisons of rod patterns. Since the comparisons are easily done, frequent checks are not an imposition on normal operations. A 1% change is larger than is expected for normal operation so a change of this magnitude should be thoroughly evaluated. A change as large as 1% would not exceed the design conditions of the reactor and is on the safe side of the postulated transients.

3/4.2 POER DISTRIBUTION LI!!ITS BASES The specifications of this section assure that the peak clacding tencerature following the postulated design basis loss-of-coolant accicent will not exceed the 2200cF limit specified in the Final Acceptance Criteria (FAC) issued in June 1971 considering the postulated effects of fuel pellet densification.

3/4.2.1 AVERAGE PLANAR LI TAR HEAT GEERATION RATE This specification assures that the peak cladding temocrature following the postulated design basis loss-of-coolant accident will not exceed the limit specified in 10 CFR 50, Appendix K.

The peak cladding tengerature (PCT) following a

postulatec 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 cependent 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 censification.

This LHGR times 1.02 is used in the heatuo coce along with the exposure dependent steacy state gap conductance and rod-to-roc local peaking factor.

The Technical Specification APLHGR is this LHCR of the highest powered rod divided by its local peaking factor.

The limiting value for APLHGR is shown in the figures in Technical Specification 3/4.2.1.

The calculational procedure used to establish the APLHGR shown in the figures in Tecnnical Specification 3/4.2.1, is based on a loss-of-coolant accicent analysis.

The analysis was performed using General Electric (GE) calculational models which are consistent with the requirements of Appendix K to 10 CFR 50. A complete discussion of each code emolayed in the analysis is presented in Reference 1.

Differences in this analysis comparec to previous analyses performed with Reference 1 are:

(1) the analysis assumes a fuel assembly planar power consistent with 102% of the MAPLHGR l

shown in the figures in Technical Specification 3/4.2.1; (2) fission procuct l

l decay is computed assuming an energy release rate of 200 EV/ fission; (3) pool boiling is assumed after nucleate boiling is lost during the ficw stagnation period; and (4) the effects of core spray entrainment and counter-current flow limitiation as described in Reference 2, are inclucec in the Itflooding calculations.

  • POWER DISTRIBUTION LI!!!TS SASES 3/4.2.2 APRM SETPOINTS The fuel cladding integrity Safety Lim'its of Specification 2.1 were based on a power distribution which would yield the design LHGR at RATED THERMAL POWER. The scram setting and rod block functions of the APRM instru-ments or APRM readings must be adjusted to ensure that the MCPR does not become less than 1.0 in the degraded situation. The scram settings and rod block settings or APRM readings are adjusted in accordance with the formula in this specification when the combination of THERMAL POWER and CMFLPD indicates a higher peaked power distribution to ensure that an LHGR transient would not be increased in the degraded condition.

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, and an analysis of abnormal I

operational transients.

For any abnormal operating transient analysis evaluation with the initial condition of the reactor being at the steady l

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 as given in Specification 2.2.1.

To assure that the fuel cladding integrity Safety Limits are not exceeded during any anticipated abnormal operational transient, the most limiting transients have been analyzed to detennine 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 l

insertion, and coolant temperature decrease.

The limiting transient which determines the required steady state MCPR limit is the load rejection trip with failure of the turbine bypass.

l This transient yields the largest a CPR. When added to the Safety Limit l

MCPR of 1.07 the required minimum operating limit MCPR of Soecification 3.2.3 is obtained.

MINIMJM CRITICAL POWER RATIO (Ccntinued)

The evaluaticn of a given transient begins with the system initial parameters shown in FSAR Table 15.1-6 that are ircut to a GE-core dynamic behavior transient computer program described in NEDO-10802(3).

Also, the voic reactivity coefficients that were ircut to the transient calculaticnal procecure are based on a new methed of calculation termed NEV which provices a better agreement between the calculated anc plant instrument power distributions.

The cutputs of this program clong with the initial MCPR form the input for further analyses of the thermally limiting bundle with the single channel transient thermal hydraulic SCAT code cescribec in NEDO-20566(1).

The princical result of this evaluation is the recucticn in MCPR causec by the transient.

The purpose of the Kf factor is to define cperating limits at other than related flow conditions. At less than 10C% of rated flow the recuire MCPR is the product of the o0I! rating limit MCPR and the Kr facter.

Specifically, the Kr facter provides the recuired thermal margin to protect against a flow ircrease transient.

The most limiting transient initiatec from less than rated flow conditions is the recirculation puma sceec w caused by a meter-generator speec control failure.

Fcr coeration in the automatic flow centrcl mece, the Kf factors assure that the operating limit MCPR of Specification 3.2.3 will not be violated shculd the mest limitino transient occur at less than rated flow.

In the manual flow control mcce, the Kr factors assure that the Safety Limit MCPR will not be violatec thould the most limiting transient.cccur at less than rated flow.

The Kr facter values snown in Figure 3.2.3-4 were cevelecee l

The l

For the manual flow control moce, the Kf factors were calculatec Suen that the maximum flow rate, as limited by the pump scoco tube set point anc the cer esponcing THERMAL POWER along the rated flow centrol line, the limiting bundle's relative pcwer, was adjusted until the MCPR was sligntly above the Safety Limit.

Using this relative bundle power, the MCPRs were calculated at different points along the rated ficw contr:1 line i

O PCWER DISTRIBUTION LIMITS EASES MINIMUM CRITICAL POWER RATIC (Continued)

For cperation in the automatic flow control mode, the same procecure was employed except the initial power distribution was established such that the MCPR was equal to the operating limit MCPR at RATED THERMAL POWER and ratec flow.

The Kr factors shown in Figure 3.2.3-4 are conservative for the l

General Electric Plant operation because the operating limit MCPRs cf Specification 3.2.3 are greater than the original 1.20 operating limit MCPP used for the generic derivation of Kr.

At THERMAL POWER levels less than or equal to 25% of RATED THERf'".

POWER, the reactor will be operating at minimum recirculation pumo sceed anc the moderator void content will be very small.

For all cesignatec control roc patterns which may be emoloyed at this point, operating plant experience inoicated that the resulting MCPR value is in excess of recuirements cy a consicerable margin.

With this icw void content, any inadvertent core flow increase would only place operation in a more conservative mode relative to MCPR. Curing initial startte testing of the plant., an MCPR evaluation will be mace at 25% of RATED THERMAL PO)ER with mininum recirculation pumo sceec.

The MCPR margin will thus be cemonstrated such that future MCPR evaluaticn belcw this Acwer level will be shown to be unnecessary.

The cally recuirement for calculating MCPR above 25% of RATED THERMAL PCwER is sufficient since power distribution shifts are very slow when there have nct been significant power or control rod changes.

The recuirement for calculating MCPR when a limiting control rod pattern is approached ensures that MCPR will be known following a change in THERMAL POWER or power snace, regardless of magnitude that could place operation at a thermal limit.

3/4.2.4 LItEAR HEAT GENERATION RATE The LHGR sCecification assures that the linear heat generation rate ir any rod is less than the cesign linear heat generation even if fuel pellet densification is pcstulated.

3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 RECIRCULATION SYSTEM Operation for longer than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with a reactor core coolant recir-culation loop inoperable is prohibited until an evaluation of the perform-ance of the ECCS during one loop operation has been performed, evaluated and determined to be acceptable.

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 accident by increasing the blowdowa area and elimi-nating the capability of reflooding the core; thus, the requirement for shutdown of the facility with a jet pump inoperable.

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 prior to startup of an idle loop. Since the coolant in the bottom of the vessel is at a lower temperature than the water in the upper regions of the core, undue stress on the vessel would result if the temperature difference were greater than 145*F.

The loop temperature must be within 50*F cf the reactor pressure vessel coolant temperature to prevent thermal shock to the recirculation pump and recirculation nozzles.

3/4.4.2.1 SAFETY / RELIEF VALVES l

The reactor coolant system safety valve function of the safety-relief valves operate to prevent the system from being pressurized above the Safety Limit of l' 25 psig. The system is designed to meet the requirements a

of the ASME Boiler and Pressure Vessel Code,Section III, for the pressure vessel, and ANSI B31.1, 1975 Code, for the reactor coolant system piping.

The capacity of the safety-relief valves is based on the full MSIV closure transient with failed trip scram, position switches, as described in Supplement 5.A of the FSAR, Section 5.A.6.

Demonstration of the safety-relief valve lift settings will occur only during shutdown and will be performed in accordance with the provisions of Section XI of the ASME Boiler and Pressure Vessel Code.

3/4.4.2.2 LOW-LOW SET SYSTEM The low-low set (LLS) system lowers the opening and closing setpoints on four preselected safety / relief valves (S/RVs). The LLS system lowers the setpoints after any S/RV has opened at its normal steam pilot setpoint when a concurrent high reactor vessel steam dome pressure scram signal is present. The purpose of the LLS is to mitigate the induced high frequency loads on the contatn-.

ment and thrust loads on the SRV discharge line. The LLS system increases the amount of reactor depressurization during an S/RV blowdown because the lowered LLS setpoints keep the four selected LLS S/RVs open for a longer time.

The high reactor vessel steam dome pressure signal for the LLS logic is provided by the exclusive analog trip channels. The purpose of installing special de-7 dicated steam dome pressure channels is to maintain separation from the RPS l'

high pressure scram functions.

REACTOR COOLANT SYSTEM BASES 3/4.4.3 REACTOR COOLANT SYSTEM LEAKAGE 3/4.4.3.1 LEAKAGE DETECTION SYSTEMS The RCS leakage detection systems are provided to monitor and detect leakage from the reactor coolant pressure boundary.

3/4.4.3.2 OPERATIONAL LEAKAGE The allowable leakage rates from the reactor coolant system have been

~

based on the predicted and experimentally observed behavior of cracks in pipes. The normally expected background leakage due to equipment design and the detection capability of the instrumentation for determining system leakage was also considered.

The evidence obtained from experiments suggests that for leakage somewhat greater than that specified for uniden-tified leakage the probability is small that the imperfection or crack associated with such leakage would grow rapidly.

However, in all cases, if the leakage rates exceed the values specified or the leakage is located and known to be PRESSURE BOUNDARY LEAKAGE the reactor will be shutdown to allow further investigation and corrective action. Service sensitive reactor coolant system Type 304 and 316 austenitic stainless steel piping; i.e., those that are. subject to high stress or that certain relatively stagnant, intermittent, or low flow fluids, requires addi-tional surveillance and leakage limits.

3/4.4.4 CHEMISTRY The water chemistry limits of the reactor coolant system are estab-lished to prevent damage to the reactor materials in contact with the coolant.

Chloride limits are specified to prevent stress corrosion cracking of the stainless steel. The effect of chloride is not as great when the oxygen concentration in the coolant is low; thus the higher limit on chlorides is permitted during full power operation.

During shutdown and refueling operations the temperature necessary for stress corrosion to occur is not present.

Conductivity measurements are required on a continuous basis since changes in this parameter are an indication of abnormal conditions. When the conductivity is within limits, the pH, chlorides and other impurities affecting conductivity must also be within their acceptable limits. With the conductivity meter inoperable, additional samples must be analyzed to ensure that the chlorides are not exceeding the limits.

The surveillance requirements provide adequate assurance that concen-trations in excess of the limits will be detected in sufficient time to take corrective action.
