DEFINITIONS VENTING 1,39 VENTING shall be the controlled process of discharging air or gas from a cor.finement to maintain temperature, pressure, humidity, concentration, or other operating condition, in such a manner that replacement air or gas is not provided or required during VENTING.
Vent, used in system names, does not imply a VENTING process.
SPENT FUEL POOL STORAGE PATTERNS:
1.40 Region I spent fuel racks contain a cell blocking device in every 4th location for criticality control.
This 4th location will be referred to as the blocked location.
A STORAGE PATTERN refers to the blocked location and all adjacent and diagonal Region I cell locations surrounding the blocked location.
Boundary configuration between Region I and Region 11 must have cell blockers positioned in the outermost row of the Region I perimeter, as shown in Figure 3.9 2.
1,41 Region 11 contains no cell blockers.
CORE OPERATING LlHITS REPORT (COLR) 1.<2 The CORE OPERATING LIMITS REPORT (COLR) is the unit-specific document that provides core operating limits for the current operating reload cycle.
These cycle-specific core operating limits shall be determined for each reload cycle in accordance with Specification 6.9.1.6.
Unit Operation within these operating limits is addressed in individual specifications.
ALLOWED POWER LEVEL HO 1,43 APL is the minimum allowable nuclear design power level for base load operation and is specified in the COLR.
OL 1.44 APL is the maximum allowable power level when transitioning into base load operation.

4m 2.1 SAFETY llMITS BASES 2.1.1 REACTOR CORE t
The restrictions of this Safety Limit prevent overheating of the fuel and possible cladding perforation which would result in the release of fission products to the reactor coolant.
Overheating of the fuel cladding is prevented by restricting fuel operation to within the nucleate boiling regime where the heat transfer coefficient is large and the cladding surface temperature is slightly above the coolant saturation temperature.
Operation above the upper boundary of the nucleate boiling-regime could result in excessive cladding temperatures because of the onset of departure from nucleate boiling (DNB) and the resultant sharp reduction in heat transfer coefficient.
DNB is not a directly measurable parameter during operation and therefore THERMAL POWER and reactor coolant temperature and pressure have been related to DNB.
This relation has been developed to predict the DNB flux and the location of DNB for axially uniform and nonuni form heat flux distributions.
The local DNB heat flux ratio (DNBR) is defined as the ratio of the heat flux that would cause DNB at a particular core location to the local heat flux and is indicative of the margin to DNB.
The DNB design basis is as follows.
ncertainties in the WRB-1 or WRB-2 correlations, plant operating parameters, nuclear and thermal parameters, fuel fabrication parameters, and computer codes are considered statistically such that there is at least a 95 percent probability with 95 percent confidence level that DNBR will not occur on the most limiting fuel rod during Condition i and II events. This establishes a design DNBR value which must be met in piant safety analyses using values of input parameters without uncertainties.
In addition, margin has been maintaired in the design by meeting safety analysis DNBR limits in performing safety analyses.
The curves of Figures 2.1-1 and 2.1-2 show the loci of points of THERMAL POWER, Reactor Coolant System pressure, and average temperature below which the calculated DNBR is. no less than the design DNBR value or the average I
enthalpy at the vessel exit is less than the enthalpy of saturated liquid.
N These curves are based on an enthalpy hot channel factor, F H of 1.70 (includes measurement uncertainty) and a reference cosine with a da,k oful.55 for axial power shape.
An-allowance is included for an increase in F{H at reduced power based on the expression:
F H = 1.70 [1 + 0.3 (1-P)]
where P is the fraction of RATED THERMAL POWER These limiting heat flux conditions are highor than those calculated for the range of all control rods fully withdrawn to the maximum allowable control rod insertion psuming axial imbalance is within the limits of F function of the Overtemperature trip.
When the axial power imbaldnc(e is not delta I) within the tolerance, the axial power imbalance effect on the Overtemperature delta T trips will reduce the setpoints to provide protection consistent with core safety limits.

LIMITING SAFETY SYSTEM SETTINGS BASES Intermediate and Source Ranae. Neutron Flux The Intermediate and Source Range, Neutron Flux trips provide core protection during reactor startup to mitigate the consequences of an uncon-trolled rod cluster control assembly bank-withdrawal' from a subcritical condition.
These trips provide redundant protection to the Low Setpoint trip-of the Power Range, Neutron Flux channels.
The Source Range channels will initiate a Reactor trip at about 105 counts per second unless manually blocked when P 6 becomes active.
The Intermediate Range channels will initiate. a Reactor trip - at a current level equivalent to approximately 25% of RATED -
THERMAL POWER unless manually blocked when P-10 becomes active.
No credit was taken for operation of the trips associated with either the Intermediate or Source Range Channels-in the accident analyses; however, their functional capability at the specified trip settings is required by this specification to enhance the overall reliability of the Reactor Trip System.
Overtemoerature AT
"- Overtemperature AT tri all i,.umbinations of pressure, p provides core protection to prevent DNB for pwer, coolant temperature, and axial power distribution, provided that-the transient is slow with respect to piping transit delays from the core to the temperature detectors, and pressure is within the range between~ the Pressurizer High 'and -Low Pressure trips.
The-Setpoint is automatically varied with:
(1) coolant temperature to correct for temperature induced changes in density and heat capacity of water and includes dynamic compensation for piping delays from the core to the loop temperature detectors, (2) pressurizer pressure, and -(3) axial-power distribution.
With normal axial power distribution, this Reactor trip limit is always below the core Safety Limit as shown in Figure 2.1-1. If axial peaks are greater than-design, as indicated by the cifference between top and-bottom power range nuclear detectors, the Reactor-trip is automatically reduced according to the notations in Table 2.2-1.
Operation with 'a reactor coolant loop out of service--requires Reactor-Trip System modification. Three loop operation is permissible after resetting the K1 input to the Overtemperature AT channels, reducing the Power Range Neutron Flux High setpoint to a value just above the three : loop maximum permissible power level, and resetting-the P-8 setpoint to its three ' loop value.
These modifications have been chosen so that, in three loop operation, each component of the Reactor Trip System performs its normal four loop.
function, prevents operation outside the safety limit curves, and prevents the DNBR from going below the design limit during normal ' operational and antici-pated transients.
Overoower AT l
The Overpower AT trip provides assurance-of fuel integrity (e.g., no -fuel pellet melting and less than 1% cladding strain) under all possible overpower conditions, limits the required range for Overtemperature AT MILLSTONE - UNIT 3 B 2-5 Amendment No. JJ,60 0005
l LIMITING SAFETY SYSTEM SETTINGS BASES Steam Generator Water level The Steam Generator W,ter Level Low Low trip protects the reactor from loss of heat sink in the event of a sustained steam /feedwater flow mismatch resulting from loss of normal feedwater.
The specified Setpoint provides allowances for starting delays cf the Auxiliary Feedwater System.
Low Shaft Soeed Reactor Coolant Pumn The Low Shaf t Speed - Reactor Coolant Pumps trip provides core protection j
to prevent DNB in the event of a sudden significant decrease in reactor coolant pump speed (with resulting decrease in flow) on two reactor coolant pumps in any two operating reactor coolant loops.
The trip setpoint ensures that a reactor trip will be generated, considering instrument errors and response times, in sufficient time to allow the DNBR to be maintained greater than the design limit following a four-pump loss of flow event.
Turbine Trio A Turbine trip initiates a Reactor trip.
On decreasing power the Pactor trip from the Turbine trip is automatically blocked by P-9 (a power level of approximately 50% of RATED THERMAL POWER); and on increasing power, reinstated automatically by P 9.
Safety In.iection Inout from ESF If a Reactor trip has not already been generated by-the Reactor Trip System instrumentation, the ESF automatic actuation logic channels will initiate a Reactor trip upon any signal which initiates a Safety Injection.
The ESF instrumentation channels which ' initiate a Safety -Injection signal are shown in Table 3.3-3.
&uctor Trio System Interlocks The Reactor Trip System interlocks perform the following functions:
P6 On increasing power P-6 allows the manual block of the Source Range trip (i.e.,
prevents premature block of Source Range trip) and deenergizes the high voltage to-the detectors. On decreasing pos:er, Source Range Level trips are automatically reactivated and high vol-tage restored.
1 P-7 On increasing power P-7 automatically enables Reactor trips on low flow in more than one reactor coolant loop, reactor coolant pump low shaf t speed, pressurizer low pressure and pressurizer hi decreasing power, the above listed trips are automa' "gh level. On ly blocked.

MARGIN from expected operating conditions of equivalent to that required by Figure 3.1-5 after xenon decay and cooldown to 200*F.
boration capability requirement occurs at EOL from fullThe maximum expected aower equilibrium xenon conditions and requires a usable volume of 21,020 gallons of 6300 ppm borated water from the boric acid storage tanks or 1,166,000 gallons of 2700 ppm borated water from the refueling water storage tank RWST).
A gallons is specified to be consi(stent with minimum RWST volume of 1,166,000 ECCS requirement.
With the RCS temperature below 200'F, one Baron Injection System is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity changes in the event the single Boron injection System becomes inoperable.
The limitation for a maximum of one centrifugal charg ng pump to be OPER-ABLE and the Surveillance Requirement to verify all charg ng pumps except the required OPERABLE pump to be inoperable below 350'F provi es assurance that a mass addition pressure transient can be relieved by the operation of a single PORV.
The boron capability required below 200'F is sufficient to provide a SHUTDOWN MARGIN of 1.3% Ak/k after xenon decay and cooldown from 200'F to 1400F, This condition requires either a usable volume of 4100 gallons of 6300 ppm borated water from the boric acid storage tanks or 250,000 gallons of 2700 ppm borated water from the RWST.
The unusable volume in each boric acid storage tank is 1300 gallons.
The contained water volume limits include allowance for water not available because of discharge line location and other physical characteristics.
The limits on contained water volume and boron concentration of the RWST also ensure a pH value of between 7.0 and 7.5 for the solution recirculated within containment after a LOCA.
This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on mechanical systems and components.
The minimum RWST solution temperature for MODES 5 and 6 is based on analysis assumptions in addition to freeze protection considerations.
The minimum / maximum RWST solution temperatures for MODES 1, 2, 3 and 4 are based on analysis assumptions.
The OPERABILITY of one Boron injection System during REFUEllNG ensures that this system is available for reactivity control while in MODE 6.

Verification that the Digital Rod Position Indicator agrees with the demanded position within 112 steps at 24, 48,120, and fully withdrawn position for the Control Banks and 18, 210, and fully withdrawn position for the Shutdown Banks provides assurances that the Digital Rod Position Indicator is operating correctly over the full range of i
indication.
Since the Digital Rod Position Indication System does not indicate the actual shutdown rod position between 18 steps and 210 steps, only points in the indicated ranges are picked for verification of agreement with demanded position.
The ACTION statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original design criteria are met.
Misalignment of a rod requires measurement of peaking factors and a restriction in THERMAL POWER.
These restrictions provide assurance of fuel rod integrity during continued operation.
In addition, those safety analyses affected by a misaligned rod are reevaluated to confirm that the results remain valid during future operation.
The maximum rod drop time restriction is consistent with the assumed rod drop time used in the safety analyses.
Measurement with T greater than or equal to 5510F and with all reactor coolant pumps operatidd9 ensures that the measured drop times will be representative of insertion times experienced during a Reactor trip at operating conditions.

These verification frequencies are adequate for assuring that the applicable LCOs are satisfied.
For Specification 3.1.3.1 ACTIONS b. and c.,
it -is incumbent upon the plant to verify the trippability of the inoperable control rod (s).
Trippability is defined in-Attachment C to a letter dated December 21, 1984, from E. P. Rahe C. O. Thomas NRC).
This may be by verification of a(Westinghouse) tocontrol system failure, usually (el that the failure is associated with the control rod stepping mechanism.
In the event the plant is unable to verify the rod (s) trippability, it must be assumed to be untrippable and thus falls under the requirements of ACTION a.
Assuming a controlled shutdown from 100% RATED THERMAL POWER, this allows approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> for this verification.

'f 3/4.2 POWER DISTRIBUTION LIMITS BASES The specifications of this section provide assuran'ce of fuel integrit during Condition I (Normal Operation) and !! (Incidents of Moderate Freqeency events by:
(1) maintaining the minimum DNBR in the core greater than or equa to the design limit during normal operation and in short term transiente, and (2) limiting the fission gas release, fuel pellet temacrature, and chd61ng mechanical properties to within assumed design cr'teria.
In additlon, limiting the peak linear power density durity Condition I events provides assurance that the initial conditions assumed for the LOCA analyses are met and the ECCS acceptance criteria limit of 22f0'F is not exceeded.
The definitions of certain hot channel and peaking factors as used in these specifications are as follows:
F(I)
Heat Flux Hot Channel Factor, is defined as the maximum local heat g
flux on the surface of a fuel rod at core elevation Z divided by the average fuel rod heat flux, allowing for manufacturing tolerances on fuel pellets and rods; and N
F Nuclear Enthalpy Rise Hot Channel Factor, is defined as the ratio of Ag the integral of linear power along the rod with the highest integrated power to the average rod power.
3/4.2.1 AXIAL FLUX DIFFERENCE The limits on AXIAL FLUX DIFFEREN(,E (AFD) assure that the F (Z) upper bound envelope of the F n
n limit specified in the Core Operating Limits Report (COLR) times the normalfled axial peaking factor is not exceeded during either normal operation or in the event of xenon redistribution following power
- changes, Target flux difference is -determined at equilibrium xenon conditions.
i The full length rods may be positioned within tlie core in accordance with their respective insertion limits and should be inserted near their normal i
position for steady state operation at high power levels.
The value of the target flux difference obtained under these conditions divided by the fraction of RATED THERMAL POWER is the target flux difference at RATED THERMAL POWER for the associated core burnup conditions. Target flux differences for other THERMAL POWER levels are obtained by multiplying the RATED THERMAL-POWER value by the appropriate fractional THERMAL POWER level.
The periodic updating of the target flux difference value is necessary to reflect core burnup considerations.

E POWER DISTRIBUTION LIMITS BASES AXIAL FLUX DIFFERENCE (Continued)
At power levels below APLND, the limits on AFD are defined in the COLR consistent with the Relaxed Axial Offset Control (RAOC) opeating procedure and limits.
These limits were calculated in a manner such that expected operational transients, e.g., load follow operations, would not result in the AFD deviating outside of those limits.
However, in the event such 9 deviation occurs, the short period of time allowed outside of the limit 3 at reduced power levels will not result in significant xenon redistribution such that the envelope of peaking fagrs would change sufficiently to prevent operation in the vicinity of the APL power level.
At power levels greater than APLHD, two modes of operation are permissible:
(1) RAOC, the AFD limit of which are defined in the COLR, and (2) base load operation, which is defined as the maintenance cf the AFD within COLR specgications band about a target value.
The RA00 operat procedure above APL is the same as that defined for operation below APL
- However, it is possible when following extended load following maneuvers that the AFD limits may result in restrictions in the maximum allowed power or AFD in order to guarantee operation with Fn(z) less than its limiting value.
To allow operation at the maximum perm'issible power level, the base load operating procedure restricts the indicated AFD to rgatively small-garget band (as specified in the COLR) and power swings (APL 1 power s APL or 100% Rated Thermal Power, whichever is lower).
For base load operation, it is expected that the plant will operate within the target band.
Operation outside of the target band for the short time period allowed will not result in significant xenon redistribution such that the envelope of peaking factors would change sufficiently to prohibit continued operation in the power region defined above.
To assure there is no residual xenon redistribution impact from past operation on tg base load operation, a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> waiting period at a power level above APL and allowed by RA00 is necessary.
During this time period load changes and rod motion are restricted to that allowed by the base load procedure.
After the waiting period, extended base load operation is permissible.
The computer determines the 1 minute average = of each of the OPERA 8LE excore detector outputs and provides an alarm message immediately if the AFD for at least 2 of 4 or 2 of 3 OPERABLE excore channels are:
(1) outside the allowed delta-1 power operating space (for RAOC operation), or (2) outside the allowed delta-1 target band (for base load operation).
These alarms are active when power is greater than (1).50% of RATED THERMAL POWER (for RAOC operation), or MILLSTONE - UNIT 3 B 3/4 2-2 Amendment No. J#,60 0088

3/4.2.2 and 3/4.2.3 r1 EAT F.LVX HOT CHANNEL FACTOR and RCS FLOW RATE AND NUCLEAR ENTHALPY RISE HOT CHANNEL FACTOR The limits on heat flux hot channel factor, RCS flow rate, and nuclear enthalpy rise hot channel factor ensure that:
(1) the design limits on peak local power density and minimum DNBR are not exceeded and (2) in the event of a LOCA the peak fuel clad temperature will not exceed the 2200'F ECCS acceptance criteria limit.
Each of these is measurable but will normally only be determined periodically as specified in Specifications 4.2.2 and 4.2.3.
This periodic surveillance is sufficient to ensure that the limits are maintaint-d provided:
Control rods in a single group move together with no individual rod a.
insertion differing by more than 12 steps, indicated, from the group demand position; b.
Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.6; i
c.
The control rod insertion limits of Specifications 3.1.3.5 and 3.1.3.6 are maintained; and d.
The axial power distribution, expressed in terms of AXIAL FLUX DIFFERENCE, is maintained within the limits.
F"H will be maintained within its limitg provided Conditions a. throu A
- d. above are maintained.
The relaxation of F as a function of THERMAL POWER AH allows changes in the radial power shape for all permissible rod insertion limits.
The F"H as calculated in Speciffcations 3.2.3.1 and 3.2.3.2 are used in A
the various accident analyses where FAH influences parameters other than DNBR, e.g.,
peak clad temperature, and tfi'us is the maximum "as measured" value allowed.

f When RCS flow rate and FN are measured, no additional allowances are necessary prior to comparison hth the limits of the Limiting Condition for Operation.
Measurement errors of 2.4% for four pop flow and 2.8% for three j
loop flow for RCS total flow rate and 4% for F determination of the design DNBR value.
AH have been allowed for in The measurement error for RCS total flow rate is based upon performing a precision heat balance and using the result to calibrate the RCS flow rate indicators.
Potential fouling of the feedwater venturi which might not be detected could bias the result from the precision heet balance in a non-conservative manner.
Therefore, a penalty of 0.1% for undetected fouling of the feedwater venturi will be added if venturis are not inspected and cleaned at least once for 18 months.
Any fouling which might bias.the RCS flow rate measurement greater than 0.1% can be detected by manitoring and trending various plant performance parameters _
If detected, action shall - be taken before performing subsequent precision heat balance measurements, i.e., either the effect of the fouling shall be quantified and compensated for-in the RCS flow rate measurement or the venturi shall be cleaned-to eliminate the fouling.

The limit of 1.02, at which corrective action is required, provides DNB and linear heat generation rate protection with x y plane power tilts.
A limiting tilt of 1.025 can be tolerated before the margin for uncertainty in F is depleted.
A limit of 1.02 was selected to provide an allowance for the g

The 2-hour time allowance for operation with a tilt condition greater than 1.02 but less than 1.09 is provided to allow identification and correc-tion of a dropped or misaligned control rod.

With less than the required reactor coolant loops in operation this specification requires that the plant be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
In MODE 3, three reactor coolant loops, and is Mode 4, two reactor coolant loops provide sufficient heat removal capablitt:y for removing core decay heat even in the event of a bank withdrawal accident; however, a single reactor coolant loop provides sufficient heat removal capacity if a bank withdrawal accident can be prevented, i.e., by opening the Reactor Trip System breakers.
In MODE 4, and in MODE 5 with reactor coolant loops filled, a single reactor coolant loop or RHR loop provides sufficient heat removal capability for removing decay heat; but sin le failure considerations require that at leasttwoloops(eitherRHRorRCS be OPERABLE.
In MODE 5 with reactor coolant loops not filled, a single RHR loop provides sufficient heat removal capability for removing decay heat; but single failure considerations, and the unavailability of the steam generators as a heat removing component, require that at least two RHR loops be OPERABLE.
The locking closed of the required valves in Mode 5 (with the loops not filled) will preclude the possibility of uncontrolled baron dilution of the Reactor Coolant System by preventing flow to the RCS of unborated water.
The operation of one reactor coolant pump adequate flow to ensure mixing, prevent strat(fication and produce gradualRC reactivity changes during boron concentrati o reductions in the Reactor Coolant System.
The reactivity change rate associated with boron reduction will, therefore, be within the capability of operator recognition and control.
The rattrictions on starting an RCP with one or more RCS cold legs less than or equal to 350'F are provided to prevent RCS pressure transients, caused by energy additions from the Secondary Coolant-System, which could exceed the limits of Appendix G to 10 CFR Part 50.
The RCS will be protected against overpressure -transients and will not exceed the limits of Appen61x G by l
either:
(1) restricting the water volume in the pressurizer and thereby providing a volume for the reactor coolant to expand into, or (2) by restricting starting of the RCPs to when the secondary water temperature of each steam generator is less than 50'F above each of the RCS cold leg temperatures.

The 2600 ppm provides for boron concentration measurement uncertainty between the spent fuel pool and the RWST.
The locking closed of the required valves during refueling operations precludes the possibility of uncontrolled boron dilution of the filled portion of the RCS.
This action prevents flow to the RCS of unborated water by closing flow paths from sources of unborated water.
3/4.9.1.2 Boron Concentration in Snent Fuel Pool The limitations of this specification ensure that in the event of a fuel assembly handling accident involving either a misplaced or dropped fuel assembly, the Kggy of the spent fuel storage racks will remain less than or equal to.95.
3/4.9.2 INSTRUMENTATION The OPERABILITY of the Source Range Neutron Flux Monitors ensures that redundant monitoring ca) ability is available to detect changes in the reactivity condition of tie core.
3/4.9.3 DECAY TIME The minimum requirement for reactor subcriticality prior to movement of irradiated fuel assemblies in the reactor vessel ensures that sufficient time has elapsed to allow the radioactive decay of the short lived fission products. This decay time is consistent with the a:sumptions used in the safety analyses.
3/4.9.4 CONTAINMENT BUILDING PENETRATIORS The requirements on containment building penetration closure and OPERABILITY ensure that a release of radioactive material within containment will be restricted from leakage to the environment.
The OPERABILITY and closure restrictions are sufficient to restrict radioactive material release from a fuel element rupture based upon the lack of containment pressurization potential while in the REFUEllHG MODE.
