These loads areintroduced by startup (heatup) and shutdown (cooldown) operations, powertransients, and reactor trips. This LCO limits the pressure and temperature changes during RCS heatup and cooldown, within the design assumptions and the stress limits for cyclic operation.

This Specification contains PIT limit curves for heatup, cooldown, and.......in~servi~ce_

lea~kage and_ hyd~rosta~ti~c

testing, and limits for the maximum rate ofchange of reactor coolant temperature.

The heatup curve provides limits forboth heatup and criticality.

Each PIT limit curve defines an acceptable region for normal operation.

Theusual use of the curves is operational guidance during heatup or cooldownmaneuvering, when pressure and temperature indications are monitored andcompared to the applicable curve to determine that operation is within theallowable region.The LCO establishes operating limits that provide a margin to brittle failure ofthe reactor vessel and piping of the reactor coolant pressure boundary(RCPB). The vessel is the component most subject to brittle failure.Therefore, the LCO limits apply mainly to the vessel.10 CFR 50, Appendix G (Ref. 1), requires the establishment of P/T limits formaterial fracture toughness requirements of the RCPB materials.

Reference I requires an adequate margin to brittle failure during normaloperation, anticipated operational occurrences, and system hydrostatic tests.It mandates the use of the ASME Code,Section XI, Appendix G (Ref. 2).The actual shift in the RTNDT of the vessel material will be established periodically by removing and evaluating the irradiated reactor vessel materialspecimens, in accordance with ASTM E 185 (Ref. 3) and Appendix H of10 CFR 50 (Ref. 4). The operating PIT limit curves will be adjusted, asnecessary, based on the evaluation findings and the recommendations ofRG 1.99, "Radiation Embrittlement of Reactor Vessel Materials" (Ref. 5).The calculations to determine neutron fluence will be developed using theBWRVIP RAMA code methodology, which is NRC approved and meets theintent of RG 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence" (Ref. 11). See FSAR Section 4.1.4.5 fordetermining fluence (Ref. 12).(continued)

Rev. 4RCS P/T" LimitsB 3.4.10BASESBACKGROUND (continued)

The P/T limit curves are composite curves established by superimposing limits derived from stress analyses of those portions of the reactor vesseland head that are the most restrictive.

At any specific

pressure, temperature, and temperature rate of change, one location within the reactorvessel will dictate the most restrictive limit. Across the span of the P/T limitcurves, different locations are more restrictive, and, thus, the curves arecomposites of the most restrictive regions.The heatup curve used to develop the P/T limit curve composite represents a different set of restrictions than the cooldown curve used to develop theP/T limit curve composite because the directions of the thermal gradients through the vessel-wall are reversed.

The thermal gradient-reversal-alters the location of the tensile stress between the outer and inner walls.The criticality limits include the Reference I requirement that they be at least40°F above the heatup curve or the cooldown curve and not lower than theminimum permissible temperature for the inservice leakage and hydrostatic testing.The consequence of violating the LCO limits is that the RCS has beenoperated under conditions that can result in brittle failure of the RCPB,possibly leading to a nonisolable leak or loss of coolant accident.

In theevent these limits are exceeded, an evaluation must be performed todetermine the effect on the structural integrity of the RCPB components.

ASME Code,Section XI, Appendix E (Ref. 6), provides a recommended methodology for evaluating an operating event that causes an excursion outside the limits.APPLICABLE SAFETYANALYSESThe P/l" limits are not derived from Design Basis Accident (DBA) analyses.

They are prescribed during normal operation to avoid encountering

pressure, temperature, and temperature rate of change conditions that might causeundetected flaws to propagate and cause nonductile failure of the RCPB, acondition that is unanalyzed.

Reference 7 establishes the methodology fordetermining the P/l" limits. Since the P/T limits are not derived from anyDBA, there are no acceptance limits related to the P/T limits. Rather, the P/Tlimits are acceptance limits themselves since they preclude operation in anunanalyzed condition.

RCS P/T limits satisfy Criterion 2 of the NRC Policy Statement (Ref. 8).(continued)

LCO The elements of this LCO are:a. RCS pressure and temperature are to the right of the applicable curvesspecified in Figures 3.4.10-1 through 3.4.10-3 and within the applicable heat-up or cool down rate specified in SR 3.4.10.1 during RCS heatup,cooldown, and inservice leak and hYdrostatic testing;b._ The temperature difference between the reactorivessel bottom~he~ad coolant and the reactor pressure vessel (RPV) coolant is _< 1450F duringrecirculation pump startup, and during increases in THERMAL POWERor loop flow while operating at low THERMAL POWER or loop flow;c. The temperature difference between the reactor coolant in the respective recirculation loop and in the reactor vessel is < 50°F during recirculation pump startup, and during increases in THERMAL POWER or loop flowwhile operating at low THERMAL POWER or loop flow;d. RCS pressure and temperature are to the right of the criticality limitsspecified in Figure 3.4.10-3 prior to achieving criticality; ande. The reactor vessel flange and the head flange temperatures are > 70°Fwhen tensioning the reactor vessel head bolting studs.These limits define allowable operating regions and permit a large number ofoperating cycles while also providing a wide margin to nonductile failure.The P/T limit composite curves are calculated using the worst case ofmaterial properties,

stresses, and temperature change rates anticipated under all heatup and cooldown conditions.

The design calculations accountfor the reactor coolant fluid temperature impact on the inner wall of thevessel and the temperature gradients through the vessel wall. Becausethese fluid temperatures drive the vessel wall temperature

gradient, monitoring reactor coolant temperature provides a conservative method ofensuring the P/T limits are not exceeded.

Proper monitoring of vesseltemperatures to assure compliance with brittle fracture temperature limitsand vessel thermal stress limits during normal heatup and cooldown, and.during inservice leakage and hydrostatic

testing, is established in PPLCalculation EC-062-0573 (Ref. 9). For P/T curves A, B, and C, the bottomhead drain line coolant temperature should be monitored and maintained tothe right of the most limiting curve.(continued)

Curve A must be used for any ASME Section III Design Hydrostatic Testsperformed at unsaturated reactor conditions.

Curve A may also be usedfor ASME Section XI inservice leakage and hydrostatic testing whenheatup and cooldown rates can be limited to 20°F in a one-hour period.Curve A is based on pressure stresses only. Thermal stresses areassumed to be insignificant.

Therefore, heatup and cooldown rates arelimited to 20°F in a one-hour period when using Curve A to ensure minimalthermal stresses.

The recirculation loop suction line temperatures shouldbe monitored to determine the temperature change rate.Curves B and C are to be used for non-nuclear and nuclear heatup andcooldown, respectively.

In addition, Curve B may be used for ASMESection Xl leakage and hydrostatic_

testing, but not for ASMESection III Design Hydrostatic Tests performed at unsaturated reactorconditions.

Heatup and cooldown rates are limited to 1 00°F in a one-hourperiod when using Curves B and C. This limits the thermal gradient throughthe vessel wall, which is used to calculate the thermal stresses in the vesselwall. Thus, the LCO for the rate of coolant temperature change limits thethermal stresses and ensures the validity of the P/T curves. The vessel belt-line fracture analysis assumes a l00°F/hr coolant heatup or cooldown rate inthe beitline area. The 100°F limit in a one-hour period applies to the coolantin the beltline region, and takes into account the thermal inertia of the vesselwall. Steam dome saturation temperature (TsAT), as derived from steamdome pressure, should be monitored to determine the beltline temperature change rate at temperatures above 212°F. At temperatures below 212°F,the recirculation loop suction line temperatures should be monitored.

During heatups and cooldowns, the reactor vessel could experience avacuum (negative pressure) at low temperatures (unsaturated conditions) and low rates of temperature change. Under a vacuum, the vessel wallwould experience a uniform compressive

loading, which would counteract the tensile stress due to any thermal gradients through the vessel wall. Toensure the margin to brittle fracture is no less than at any other pressure, Curves A, B, and C require a minimum vessel metal temperature of 70°Fwhen the reactor vessel is at a negative pressure.

Rev. 4RCS PIT LimitsB] 3.4.10BASESLCO(continued)

Violation of the limits places the reactor vessel outside of the bounds of thestress analyses and can increase stresses in other RCS components.

Theconsequences depend on several factors, as follows:a. The severity of the departure from the allowable operating pressuretemperature regime or the severity of the rate of change of temperature;

b. The length of time the limits were violated (longer violations allow thetemperature gradient in the thick vessel walls to become morepronounced);

andc. The existences, sizes, and orientations of flaws in the vessel material.

APPLICABILITY The potential for violating a P/T limit exists at all times. For example, PITlimit violations could result from ambient temperature conditions that result inthe reactor vessel metal temperature being less than the minimum allowedtemperature for boltup. Therefore, this LCO is applicable even when fuel isnot loaded in the core.ACTIONSA.1 and A.2*1Operation outside the PIT limits while in MODES 1, 2, and 3 must becorrected so that the RCPB is retumed to a condition that has been verifiedby stress analyses.

The 30 minute Completion Time reflects the urgency of restoring theparameters to within the analyzed range. Most violations will not be severe,and the activity can be accomplished in this time in a controlled manner.B]esides restoring operation within limits, an evaluation is required todetermine if RCS operation can continue.

The evaluation must verify theRCPB integrity remains acceptable and must be completed if continued operation is desired.

Several methods may be used, including comparison with pre-analyzed transients in the stress analyses, new analyses, orinspection of the components.

Either possibility indicates a need for more careful examination of the event, best accomplished with the RCS at reduced pressure andtemperature.

With the reduced pressure and temperature conditions, thepossibility of propagation of undetected flaws is decreased.

This Frequency is considered reasonable in view of the controlroom indication available to monitor RCS status. Also, since temperature rate of change limits are specified in hourly increments, 30 minutes permits areasonable time for assessment and correction of minor deviations.

Surveillance for heatup, cooldown, or inservice leakage and hydrostatic testing may be discontinued when the criteria given in the relevant plantprocedure for ending the activity are satisfied.

SR 3.4.10.3 and SR 3.4.10.4Differential temperatures within the applicable limits ensure that thermalstresses resulting from the startup of an idle recirculation pump will notexceed design allowances.

In addition, compliance with these limitsensures that the assumptions of the analysis for the startup of an idlerecirculation loop (Ref. 10) are satisfied.

Performing the Surveillance within 15 minutes before starting the idlerecirculation pump provides adequate assurance that the limits will not beexceeded between the time of the Surveillance and the time of the idlepump start.An acceptable means of demonstrating compliance with the temperature differential requirement in SR 3.4.10.4 is to compare the temperatures ofthe operating recirculation loop and the idle loop. If both loops are idle,compare the temperature difference between the reactor coolant within theidle loop to be started and coolant in the reactor vessel.(continued)

REQUIREMENTS SR 3.4.10.3 has been modified by a Note that requires the Surveillance tobe performed only in MODES 1, 2, 3, and 4. In MODE 5, the overall stresson limiting components is lower. Therefore, AT limits are not required.

TheNote also states the SR is only required to be met during a recirculation pump start-up, because this is when the stresses occur.SR 3.4.10.5 and SR 3.4.10.6Differential temperatures within the applicable limits ensure that thermal--stres-es resultingg from increases irn-THERMAL POWER or recirc~lation loop flow during single recirculation loop operation will not exceed designallowances.

Performing the Surveillance within 15 minutes beforebeginning such an increase in power or flow rate provides adequateassurance that the limits will not be exceeded between the time of theSurveillance and the time of the change in operation.

An acceptable means of demonstrating compliance with the temperature differential requirement in SR 3.4.10.6 is to compare the temperatures ofthe operating recirculation loop and the idle loop.Plant specific startup test data has determined that the bottom head is notsubject to temperature stratification at power levels > 27% of RTP and withsingle loop flow rate _>21,320 gpm (50% of rated loop flow). Therefore, SR 3.4.10.5 and SR 3.4.10.6 have been modified by a Note that requiresthe Surveillance to be met only under these conditions.

The Note forSR 3.4.10.6 further limits the requirement for this Surveillance to excludecomparison of the idle loop temperature if the idle loop is isolated from theRPV since the water in the loop cannot be introduced into the remainder ofthe. Reactor Coolant System.SR 3.4.10.7.

SR 3.4.10.8, and SR 3.4.10.9Limits on the reactor vessel flange and head flange temperatures aregenerally bounded by the other P/T limits during system heatup andcooldown.

However, operations approaching MODE 4 from MODE 5 and inMODE 4 with RCS temperature less than or equal to certain specified values require assurance that these temperatures meet the LCO limits.(continued)

The flange temperatures must be verified to be above the limits 30 minutesbefore and while tensioning the vessel head bolting studs to ensure thatonce the head is tensioned the limits are satisfied.

When in MODE 4 withRCS temperature

< 80°F, 30 minute checks of the flange temperatures arerequired because of the reduced margin to the limits. When in MODE 4with RCS temperature

< 1 00°F, monitoring of the flange temperature isrequired every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months to ensure the temperature is within the specified limits.The 30 minute Frequency reflects the urgency of maintaining thetemperatures-within limits, and also limits the time that the temperature limits could be exceeded.

The 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months Frequency is reasonable based onthe rate of temperature change possible at these temperatures.
