2.1 SAFETY LIMITS BASES 2.1.1 REACTOR CORE 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 boi regime could result in excessive cladding temperatures because of the
' et of departure from nucleate boiling (DNB) and the resultant sharp eeduction 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 through correlations which have been g
developed to predict the DNB flux and the location of DNB for axially uniform and non-uniform heat flux distributions.
The local DNB heat flux ratio, DNBR, defined as the ratio of the heat flux that would cause DNB at a particular core location to the local heat flux, is indicative of the margin to DNB.
The DNB design basis is as follows: uncertainties in the WRB-1 and WRB-2 correlations, plant operating parameters, nuclear and thernal parameters, fuel fabrication parameters, and sputer 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 or II events. This establishes a design DNBR value which must be met in plant safety analyses using values of input parameters without uncertainties.
The curves of Figure 2.1-1 shows the loci of points of THERMAL POWER, Reactor Coolant System pressure and average temperature for which the minimum DNBR is no less than the design DNBR value, or the average enthalpy at the vessel exit is equal to the enthalpy of saturated liquid.
t SALEM - UNIT 1 B 2-1 Amendment No. 201
.. ~ _..-.
I SAFETY LIMITS BASES The curves are based on an enthalpy hot channel factor, F "as, and a reference cosine with a peak of 1.55 for axial power shape. An allowance is included for an increase in r"aa at reduced power based on the expressions F "an [1. 0 + Pran (1. 0 - P ) )
r"an
=
where F "aw is the lindt at RATED THERHAL POWER (RTP) specified in the Core Operating Limits Report (COLR).
PraH is the Power factor Multiplier for r"aH spe. #ied in the COLR, and P is THERMAL POWER RATED THERMAL POWER These limiting heat flux conditions ace higher than those calculated for the range of all control rod positions from rods FULLY WITHDRAWN to the l
maximum allowable control rod insertion assuming tho axial power imbalance is within the limits of the ft(AI) function of the overtemperature trip. When the axial power imbalance is not within the tolerance, the axial power imbalance effect on the overtemperature AT trips will reduce the setpoints to provide protection consistent with core safety limits.
2.1.2 REACTOR COOLANT SYSTEM PRESSURE The restriction of this Safety Limit protects the integrity of the Reactor Coolant System from overpressurization and thereby prevents the release of radionuclides contained in the reactor coolant from reaching the containment atmosphere.
The reactor pressure vessel and pressurizer are designed to Section III of the ASME Code for Nuclear Power Plant which permits a maximum transient pressure of 110% (2735 psig) of design pressure. The Reactor Coolant System piping and fittings are designed to ANSI B 31.1 1955 Edition while the valves are designed to ANSI B 16.5, MSS-SP-66-1964, or ASME Section III-1968, which permit maximum transient pressures of up to 120% (2985 psig) of component design pressure.
The Safety Limit of 2735 psig is therefore consistent with the design criteria and associated code requirements.
The entire Reactor Coolant System is hydrotested at 3107 psig, 125% of design pressure, to demonstrate integrity prict to initial operation.

i LIMITING SAFETY SYSTEM SETT M 4
operation with a reactor coolant loop out of service below the 4 loop P-8 set point does not require reactor protection system cet point modification because the P-8 set point and associated trip will prevent DNB during 3_ loop operation exclusive of the overtemperature AT set point. Three loop operation above the 4 loop P-8 set point has not been evaluated and is not permitted.
Overoower AT i
The overpower AT reactor trip provides assurance of fuel integrity, e_.g.,
no melting, under all possible overpower conditions, limits the required range for overtemperature AT protection, and provides a backup to the High Neutron Flux trip. The setpoint includes corrections for changes in density and heat capacity of water with temperature, and dynamic compensation for piping delays-from the core to the loop temperature detectors. No credit was taken for operation of this trip in the accident analyses; however, its functional capability at the specified trip setting is required by this specification to enhance the overall reliability of the Reactor Protection System.
i Pressurizer Pressure i
The Pressurizer High and Low Pressure trips are provided to limit the pressure range in which reactor operation is permitted. The High Pressure trip is backed up by the pressurizer code safety valves for RCS overpressure protection, and in therefore set lowe than the set pressure for these valves j.
(2485 psig). The Low Pressure trip provideo protection by tripping the reactor in the event of a loss of reactor coolant pressure, i
Pressurizer Water Level The Pressurizer High Water Level trip ensures protection against Reactor coolant System overpressurization by limiting the water level to a volume
' sufficient to retain a steam bubble and prevent water relief t

i overall reliability of the Reactor Protection System.
j Loss oi Flow The Loss of Flow trips. provide core protection to prevent DNB in the event of a loss'of one or more reactor coolant pumps.
l Above 11 percent of RATED THERMAL POWER, an automatic reactor trip will occur if the flow in any two loops drop below 90% of nominal-full loop flow.
'Above 36% (P 8) of RATED THERMAL POWER, automatic reactor trip will occur if the-flow-in any single loop drops below 90% of nominal full loop flow. This-
"latter trip will prevent the minimum value of the DNBR from going below the design DNBR value during normal operational transients.
Steam Generator Water Level The steam Generator Water Level Low-Low trip.provides core protection by preventing operation with the steam generator water level below the minimum volume required for adequate heat removal capacity.
The specified setpoint provides allowance that there will be sufficient water inventory in the steam generators at the time of trip to allow for starting delays of the auxiliary feedwater system.

3/4.1 REACTIVITY CONTROL SYSTEMS BASES 3/4.1.1 BORATION CONTROL 3/4.1.1.1 and 3/4.1.1.2 SHUTDOWN MARGIN A sufficient SHUTDOWN MARGIN ensures that 1) the reactor can be made suberitical 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 suberitical to preclude inadvertent criticality in the shutdown condition.
SHUTDOWN MARGIN requirements vary throughout core life as a function of fuel depletion, RCS boron concentration, and RCS T,g.
The most restrictive condition occurs at EOL, with Tes at no load operating temperature, and is associated with a postulated steam line break accident and resulting uncontrolled hCS cooldown.
In the analysis of this accident, a minimum SHUTDOWN MARGIN of 1.3% Ak/k is initially required to control the reactivity transient. Accordingly, the SHUTDOWN MARGIN requirement is based upon this limiting condition and is consistent with FSAR safety analysin assumptions.
With T, s 200'F, the reactivity transients resulting from a postulated steam line break cooldown are minimal and a 1% Ak/k shutdown margin provides adequete protection.
3/4.1.1.4 MODERATOR TEMPERATURE COEFFICIENT (MTC)
The limitations en MTC are provided to ensure that the value of this coeff.cient remains within the limiting condition assumed in the accident and transient analyses.

3/4.1 REACTIVITY CONTROL SYSTEMS BASES 3/4.1.1.4 MODERATOR TEMPERATURE COEFFICIENT (MTC) (Continued)
The MTC values of this specification are applicable to a specific set of plant conditions; accordingly, verification of MTC values at conditions other than those explicitly stated will require extrapolation to those conditions in order to permit an accurate comparison.
The most negative MTC value equivalent to the most positive moderator density coefficient (MDC), was obtained by incrementally correcting the MDC used in the FSAR analysis to nominal operating conditions. These corrections involved (1) a conversion of the MDC used in the FSAR analysis to its equivalent MTC, based on the rate of change of moderator density with temperature at RATED THERMAL POWER conditions, and (2) subtracting from this value the largest dif fert. ices in MTC observed between EOL, all rods withdrawn, RATED THERMAL POWER conditions, and those most adverse conditions of moderator temperature and pressure, rod insertion, axial power skewing, and xenon concentration that can occur in normal operation and lead to a significantly more negative EOL MTC at RATED THERMAL POWER.
These corrections transformed the MDC value used in the FSAR analysis into the limiting End of Cycle Life (EOL) MTC value.
The 300 ppm surveillance limit MTC value represents a conservative value at a core condition of 300 ppm equilibrium boron concentration that is obtained by correcting the limiting EOL MTC for burnup and boron concentration.
The surveillance requirements for measurement of the MTC at the beginning and near the end of the fuel cycle are adequate to confirm that the MTC remains with its limits since this coefficient changes slowly due principally to the reduction in RCS boren concentration associated with fuel burnup.
3/4.1.1.5 MINIMUM TEMPERATURE FOR CRITICALITY This specification ensures that the reactor will not be made critical with the Reactor Coolant System average temperature less than 541*F.
This limitation is required to ensure 1) the moderator temperature coefficient is within its ant.lyzed tempera:ure range, 2) the protective instrumentation is within its normal operating range, 3) the P-12 interlock is above its allowable setpoint, 4) the preosurizer is capable of being in an OPERABLE status with a steam bubble, and 5) the reactor pressure vessel is above its minimum RTNDT temperature.
SALEM - UNIT 1 B 3/4 1-2 Amendment No.201
l REACTIVITY CONTROL SYSTEMS BASES 3/4.1.2 BORATION SYSTj211 The boron injection system ensures that negative reactivity control is available during each mode of facility operation. The components required to perform this function include:
- 1) borated water sources, 2) charging pumps,
- 3) separate flow paths, 4) boric acid transfer pumps, and 5) an emergency power supply from OPERABLE diesel generators.
With the RCS average temperature a 350'F, a minimum of two boron injection flow paths are required to ensure single functional capability in the event an assumed failure renders one of the flow paths inoperable.
The
'f boration capability of either flow path is suf ficient to provide a SHUTDOWN g
MARGIN from expected operating conditions of 1.3% delta k/k after xenon decay l
and cooldown to 200'F.
The maximum expected boration capability (minimum boration volume) requirement is established to conservatively bound expected operating conditions throughout core operating life.
The analysis assumes that the most reactive control rod is not inserted into the core. The maximum expected boration capability requirement occurs a' EOL from full power equilibrium xenon conditions and requires borated water from a boric acid tank in accordance with TS Figure 3.1-2, and additional makeup from either:
(1) the second boric acid tank and/or batching, or (2) a maximum of 41,800 gallons of 2,300 ppm borated water from the refueling water stotage tank.
With the refueling water storage tank as the only boratcJ water source, a maximum of 73,800 gallons of 2,100 ppm borated water is required.
However, to be consistent with the ECCS requirements, the RWST is required to nave a minimum contained volume of 350,000 gallons during operations in MODES 1, 2, 3
and 4.
The boric acid tanks, pumps, valves, and piping contain a boric acid solution concentration of between 3.75% and 4.0% by weight.
To ensure that the boric acid remains in solution, the tank fluid temperature and the process pipe wall temperatures are monitored to ensure a temperature of 63'F, or above is maintained.
The tank fluid and pipe wall temperatures are monitored in the main control rcom. A 5'F margin is provided to ensure the boron will not precipitate out.
Should ambient temperature decrease below 63*F, the boric acid tank heaters, in conjunction with boric acid pump recirculation, are capable of maintaining the boric acid in the tank and in the pump at or above 63*F.
A small amount of beric acid in the flow path between the boric acid recirculation line and the auction line to the charging pump will precipitate out, but it will not cause flow blockage even with temperatures below 50*F.
With the RCS temperature below 350*F, one 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 change in the event the single injection system becomes inoperable.

l 3 /4. 2 POWER DISTRIBtTTION LIMITS o
BASES 1
The specifications of this section provide assurance of fuel integrity during Condition 1 (Normal Operation) and II (Incidents of Moderate Frequency) events by: (a) meeting the DNB design criterion during normal operation and in short teim transients, and (b) limiting the fission gas release, fuel pellet temperature and cladding mechanical properties to within assumed design criteria.
In addition, limiting the peak linear power density during Condition I events provides assurance that the initial conditions assumed for the LOCA analyses are met and the ECCS acceptance criteria limit of 2200*F is not exceeded.
The definitions of hot channel-factors as used in these specifications are ar follows:
Fn(Z)
Heat Flux Hot Channel Factor, is defined as the maximum local heat 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.
N F 3n Nuclear Enthalpy Rise Hot Channel Factor, is defined as the ratio of the integral of linear power along the rod with the highest integrated power to the average rod power.
Fn(Z)
Radial Peaking Factor is defined as the ratio of peak power density to average power density in the horizontal plane at core elevation Z.
3/4.2.1 AXIAL FLUX DIFFERENCE (AFD)
The limits on AXIAL FLUX DIFFERENCE assure that the Fg(Z) upper bound envelope of the Fq limit specified in the Cote Operating Limits Report (COLR) times the normalized axial peaking factor is not exceeded during either normal operation or in the event of xenon redistribution following powar changes.
Target flux difference is determined at equilibrium xenon conditions.
The full length rods may be positioned within the core in accordance with their respective insertion limits and should be inserted near their normal position for steady state operation at high power le.els.
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 Jevel. The periodic updating of the target flux difference value is necessary to reflect core burnup considerations.
SALEM - UNIT 1 B 3/4 2-1 Amendment No. 201
I l
POWER DISTRIBUTION LIMITS BAS"S Although it is intended that the plant will be operated with the AXIAL FLUX DIFFERENCE within the target band in the COLR per Specification 3.2.1 about the target flux difference, during rapid plant THERMAL POWER reductions, control rod motion will cause the AFD to deviate outside of the target band at reduced THERMAL POWER levels. This deviation will not affect the xenon redistribution sufficiently to change the envelope of peaking factors which may be reached on a subsequent return to RATED THERMAL POWER (with the AFD within the target band) provided the time duration of the deviation is limited. Accordingly. 4 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> penalty deviation limit cumulative during the previous 24 aours is provided for operation outside of the target band but within the limits specified in the COLR while at THERMAL POWER levels between 50% and 90% of RATED THERMAL POWER.
For THERMAL POWER levels between 15% and 50% of rated THERMAL POWER, deviations of the AFD outside of the target band are less significant.
The penalty of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> actual time reflects this reduced significance.
Provisions for monitoring the AFD are derived from the plant nuclear instrumentation system through the AFD Monitor Alarm. A control room recorder continuously displays the auctioneered high flux difference and the target band limits as a function of power level. An alarm is received any time the auctioneered high flux difference exceeds the target band limits.
Time outside the target band is graphically presented on the strip chart.

EQWJMIS_TRIBUTION LIMITS BASES 3/4.2.2 and 3/4.2.3 HEAT FLUX AND NUCLEAR ENTHALPY HOT CHANNEL AND PADIAL N
PFtWING FACTORS - Fg(Z), F gng p gg) h The limits on heat flux and nuclear enthalpy hot channel factors 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.
e Each of these hot channel factors are 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 insure that the hot channel factor limits are maintained provided:
a.
Control rod in a single group move together with no individual rod insertion differing by more than i 12 steps from the group demand
- position, b.
Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.5.
c.
The control rod insertion limits of Specifications 3.1.3.4 and 3.1.3.5 are maintained.
d.
The axial power distribution, expressed in terms of AXIAL FLUX DIFFERENCE, is maintained within the limits.
N The relaxation in F AH as a function of THERMAL POWER allows changes in N
the radial cower shape for all permissible rod insertion limits.
F H will be maintained within its limits provided conditions a thru d above, are maintained.
When an Fq measurement is taken, both experimental error and manufacturing tolerance must be allowed for 5% is the appropriate allowance for a full core map taken with the incore detector flux mapping system and 3%
is the appropriate allowance for manufacturing tolerance.
N When F is measured, experimental error must be allowed for and 4% is the appropriate allowance for a full core map taken with the incore detection N
system. The specified limit for F also Contains an 8% allowance for uncertainties which mean that normal operation will result in Fa g pRP
/1.08 where FRTP is the limit of RATED THERMAL POWER (RTP)
N AH H
specified in the CORE OPERATING LIMITS REPORT (COLR). The 8% allowance is based on the following considerations:

POWER DISTRIBUTION LIMITS BASES a.
abnorum1 perturbations in the radial power shape, such as from rod misalignment, effect FN nere directly Fq, b.
although rod movement has a direct influence upon limiting Fo to within its limit, such control is not readily available to limit N
F 33g c.
errors in prediction for control power shape detected during startup physico tests can be compensated for in Fq by restricting axial flux N
distributions.
This compensation for F H is less readily available.
The radial peaking f actor F,y(z) is measured periodically to provide assurance that the hot channel factor, Fn(z), remains within its limit. The Fay limit for Rated Thermal Power (FRTP
), as provid$d in the COLR per opecification ay 6. 9.1. 9, was determined from expected powar control maneuvers over the full range of burnup conditions in the core.
3/4.2.4 OUADRANT POWER TILT PATIO The quadrant power tilt ratio limit assures that the radial power distribution satisfies the design values used in the power capability analysis. Radial power distribution measurements are inade during startup testing and periodically during power operation.
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 Fq is depleted. The limit of 1.02 was selected to provide an allowance for the uncertainty associated with the indicated power tilt.
The two hour time allowance for operation with a tilt condition greater than 1.02 but less than 1.09 is provided to allow identification and correction of a dropped or misaligned rod.
In the event such action does not correct the tilt, the margin for uncertainty on Fq is reinstated by reducing the power by 3 percent from RATED THERMAL POWER for each percent of tilt in excess of 1.0.

3/4.4 REACTOR COOLANT SYSTEM BASES 3/4.4.1 REACTOR COOLANT LOOPS AND COOLANT CIRCULATION The plant is designed to operate with all reactor coolant loops in operation, and m et the DNB criterion during all normal operations and anticipated transients.
In MODES 1 and 2 with less than all coolant loops in operation, this specification requires that the plant be in at least HOT STANDBY within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
In MODE 3, a single reactor coolant loop provides sufficient heat removal for removing decay heat; but, single failure considerations require all loops be in operation whenever the rod control system is energized and at least one loop be in operation when the rod control system is deenergized.
In MODE 4, a single reactor coolant loop or RHR loop provides sufficient
' heat removal for removing decay heat; but, single failure censiderations require that at least 2 loops be OPERABLE. Thus, if the reactor coolant loops are not OPERABLE, this specification requires that two RER loops be OPERABLE.
In MODE 5, single failure considerations require that two RHR loops be OPERABLE. The provisions of Sections 3.4.1.4 and 3.9.8.2 (paragraph (b) of footnote (+)] which permit one service water header to be out of service, are based on the following:
I.
The period of time during which plani operatirns rely upon the provisions of this footnote shall be lioited to a cumulative 45 days for any single outage, and 2.
The Gas Turbine sk-ll be operable, as a backup to the diesel generators, in the event of a loss of offsite power, to supply the applicable loads.
The basis for OPERABILITY is one successful startup af the Gas Turbine no more than 14 days prior to the beginning of the Unit outage.
The operation of one Reactor Coolant Pump or one RER Pump provides adequate flow to ensure mixing, prevent stratification and produce gradual reactivity changes during Boron concentration reductions in the Reactor Coolant System.
The reactivity change eate associated with Boron concentration reductions will, therefore, be within the capability of operator recognition and control.
The restrictions on starting a Reactor Coolant Pump below P-7 with one or more RCS cold legs less than or equal to 312*F are provided to prevent RCS pressure transie:cs, caused by energy additions from the secondary system, which could exceed the limits of Appendix G to 10CFR Part 50.
The RCS will be protected against overpressure transients and will not exceed the limits of Appendix 0 by either (1) restricting the water volume in the pressurizer (thereby providing a volume into which the primary coolant can expand, or (2) by restricting the starting of Reactor Coolant Pumps to those times when secondary water temperature in each steam generator is less than 50*F above each of the RCS cold leg temperatures.
