The 37,000 gallon limit in the refuelinq watex .etarage tank for Mode* s and 6 ie based upon 21,210 gallons that is undetectable due to lower tap location, 8,550 gallons for instrument error, 7,100 g~lLon* 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.Q for the aolution recirculated within containment after a LOCA. 'nlis pH b&nd-.ainimizes the evolution of iodine and minimizes the effect of chloride and cau*tic stre*s corro*ion 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 mystem during RBPOBLING ensures that this syatem ia available for reactivity control while in llJDB 6. 3/4.l.3 tl'YABLi CONTROL A$SIMBLIIS The specifications of this section en*ure that (1) acceptable power distribution limits are maintained, (2) the minimum SHDTDOWR MARGIN is maintained, and (3) limit the potential effects of rod mis-alignment on associated accident analyse*. OPBRABILITY' of the control rod position indicators is required to determin~ control rod positions and thereby ensure compliance with the control rod ali~"'lDent and insertion limits. OPBRABLB condition for the analog rod position indicators is defined LB being capable of indicating rod position to within.;+/- 12 step* of the baiJk demand position for a range of poait1ona. For the Snu *, and Control Ban>t A this range is defined as the group demand counter indicated po*ition between a and 30 steps withdrawn inclusive, and between 200 and 228 step* withdrawn inclusive. 'I1li* permit* the operator to verify that the control rods in these banks are either fully withdrawn or fully in*erted, the normal operating modes for the** bmika. JCnowledge of the*e banks positions in these ranges satisfies all acci~ analymi* ***wnption* concerning their poaition. 'nle range for control Beak B i* dllfined a* the group demand counter indicated position between O alJd 30 *tep* withdrawn inclusive, and between 160 and 228 steps withdrawn incluaive. Por Control Ban>ts C and D the range is defined as the group demand counter indicated position between o and 228 steps withdrawn. Comparison of the group demand counters to the bank 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 ei;*~i::ifically established for each cycla by the RGload Safety Analysis fer tl:'.at cycle. Thie position will be within the band established by "PULLY WITHDRAWN" and will be administratively controlled. This band is allowable to minimize RCCA wear, pursuant to Information Notice 87-19.
