• RiACTiyrTY.CONTROL SYSTEMS BASES The-bor.c;:in capability required belo"' 200"F ia a*u.fficient to provide a SHUTDOWN MARGIN of l\' delta k/k .&fter xenon dec.si.y and cooldown from 2oo*r to 140°F. This condition requires either 2,600 ga1lons of 6,560 ppm borated water fran the boric acid storage tanks or 7,1u0 gallon* of 2,300 ppm borated water fran 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 gallon* 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 ll.O for the solution recirculated within containment after a LOCA. This pH band minimizes the 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 REFU'BLING ensures that this system is available for reactivity control while in MODE 6. 3/4.l.3 MQVABLE CONTBOL A$SEMBLIEf.

The specifications of this section ensure that (ll acceptable power distribution limits are maintained, (2) the minimum SHCTDOWN MARGIN is maintained, and (3) limit the potential effecta of rod mis-alignment on associated accident analyses.

of the control rod position indicators is required to detei -ine control rod positions and thereby ensure compliance with the control rod alignment and insertion limits. OPERABLE condition for the analog rod position indicators is defined as being capable of indicating rod position to within :t 12 stepo o the bank demand position for a range of positions.

For the Shut own B a, and Control Bank A this range is defined as the group demand counter indicated position between O and 30 steps withdrawn inclusive, and between 200 and 228 steps withdrawn inclusiva.

This permit* the operator to verify that the control rods in these banks are either fully withdrawn or fully inserted, the normal operating modes for these banks.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 position between O 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 dezna.nd counter indicated position between O and 228 steps withdrawn.

Comparison of the group demand counters to the insertion limits with verification of rod position with the analog rod position indicators (after thermal soak after rod motion) is sufficient verification that the control rods are above the insertion limits. The full out position will be specifically for each cycle by the Reload Safety Analysis for that cycle. This position will be within the band established by RF'ULL WITHDRAWN" and will be administratively controlled.

Thia band is allowable to minimize RCCA wear, pursuant to Information Notice 87-19.

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.
