REACTIVITY CONTROL SYSTEMS BASES The boron capability required below 200'F is suf ficient to provide a SHUTDOWN MARGIN of 14 delta k/k after xenon decay and cooldown from 200'F to 140'F.

This condition requires either 2,600 gallons of 6,560 ppm borated water from the beric acid storage tanks or 7,100 gallons of 2,300 ppm borated water from the refueling water storage tank.

The 37,000 gallons limit in the refueling water storage tank for Modes 5 and 6 is based upon 21,210 gallons that is undetectable due to lower tap location, 8,550 gallons for instrument error, 7,100 gallons required for shutdown margin, and an additional 140 gallons due to rounding up.

The limits on contained water volume and boron concentration of the RWST also ensure a~pH value of between 8.5 and 11.0 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 contained water volume limits include allowance for water not available because of discharge line location and other physical characteristics.

The OPERABILITY of one boron injection system during REFUELING ensures that this system is available for reactivity contro2 while in MODE 6.

3/4.1.3 MOVABLE CONTROL ASSEMPLIES The specifications of this section ensure that (1) acceptable power distribution limits are maintained, (2) the minimum SHUTDOWN MARGIN is maintained, and (3) limit the potential effects of rod mis-alignment on associated accident analyses. OPERABILITY of the control rod position indicators is required to determine control rod positions and thereby ensure compliance with the control rod alignment and insertion limits. OPERABLE condition for the analog rod position indicaters is defined as being capable thebankdemandpositionforarangeofpositions.FortheShutdownBanks,andl of indicating rod position to within the allowed rod misalignment relative to Control Bank A this range is defined as the group demand counter indicated position between 0 and 30 steps withdrawn inclusive, and between 200 and 228 steps withdrawn inclusive. This. permits the operator to verify that the control rodn in these banks are either fully withdrawn or fully inserted, the normal operating modes for these banks.

Knowledge of these banks positions in these ranges satisfies all accident analysis assumptions concerning their position. The range for control Bank B is defined as the group demand counter indicated position between 0 and 30 steps withdrawn inclusive, and between 160 and 228 steps withdrawn inclusive.

For Control Banks C and D the range is defined as the group demand counter indicated position between 0 and 228 steps withdrawn. Compsrison of the group denand counters to the bank insertion limits with verification of rod position with the analog rod position indicatots (after thermal soak after rei motion) is sufficient verification that the control rods are above the insertion limits. The full out position will be specifically established for each cycle by the Reload Safety Ann ysis for that cycle. This position will be within the band established by " FULL WITHDRAWN" and will be administratively controlled. This band is allowable to minimize RCCA wear, pursuant t0 Informa*. ion Notice 87-19.

POWER DISTRIBUTION LIMITS RASES 3 /4.2 7 and 3 /4.2. 3 HEAT FLUX AND NUCLEAR ENTHALPY HOT CHANNEL AND RADIAL PEAXING FACTORS - Fn(Z) AND F"an The limits on heat flux and nuclear enthalpy hot channel factors and RCS flow rate 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 hot channel factors are measurable but will normally only be determined periodically as rpecified in Specifications 4.2.2 and 4.2.3.

This periodic surveillance is sufficient to insure that the limits are maintained provided:

a.

Control rod in a single group move together with no individual rod insertion differing from the group demand position by more than the l allowed rod misalignment.

b.

Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.5.

c.

The centrol rod insertion limits of Specifications 3.1.3.4 and 3.1.3.5 are naintained, d.

The axial power distribution, expressed in terms of AXIAL FLUX DIFFERENCE, is maintained within the limits.

The relaxat:on in F",n as a function of THERMAL POWER allows changes in the radial power shape for all permissible rod insertion limits.

F",n will be maintained within its limits prcvided conditions a through d above, are maintained.

When an Fg measurement is taken, both experimental error and manufacturing tolerance must be allowed for. Five percent 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.

When F",n is measured, experimental error must be allowed for and 4% is the appropriate allowance for a full core map tan with the incore detection e

system. The specified limit for F",n also contains an 8% allowance for uncertainties which rean that normal operation will result in F"an s1.55/1.08 The 8% allowance is based on the following considerations:
