CRYSTAL RIVER - UNIT 3 3/4 5 7 Amendment No. 146
The limit established for minimum boron concentration is based upon ensuring that with a minimum BWST level following a LOCA, the reactor will remain subcritical in the cold condition following mixing of the BWST and RCS water volumes. Large break LOCAs assume all control rods remain withdrawn from the core.
The minimum and maximum boron concertration limits both ensure that the solution in the reactor building emergency sump following a LOCA is within a pH range of 7.0 to 11.0 prior to recirculating the solution through the low pressure injection system and the reactor building spray system.
This pH range will minimize the evolution of iodine and minimize the effects of chloride and caustic stress corrosion cracking on the mechanical systems and componcnts within the reactor building.
The maximum boron concentration in the BWST is also based on the potential for boron precipitation in the core during the icng term cooling period following a LOCA.
BWST boron concentrations in excess of the limit could 2sult in precipitation earlier than assumed in the analyses.
Tho OPERABILITY of one boron injection system during REFUELING ensures that this system is available for reactisity control while in Mode 6.
3/4.1.3 MOViB1E CONTROLAJSEMBLIES The specification of this section (1) ensure that acceptable power distribution limits are maintained, (?) ensure that the minimum SHUTDOWN MARGIN is maintained, and (3) limit the potential effect of a rod ejection accident. OPERABILITY of the control rod position indicators is required to determine control ~ rod positions and thereby ensure compliance with the ;ontrol rod alignment and insertion limits.
(
The ACTION statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ersure that the original i
criteria are met.
For example, misalignment of a safety or regulating rod requires a restriction in THERMAL POWER.
The reactivity worth of a misaligned rod is limited for the remainder of the fuel cycle to prevent exceeding the assumptions used in the safety analysis.
The position of a rod declared inoperable due to misalignment should not be included in computing the average group position for determin n.g the OPERABILITY of rods with lesser misalignments.

The contained water volume limit includes an allowance for water-not usable because of tank discharge line location or other physical characteristics. The limits on contained water volume and boron concentratior ensure a pH value of between 7.0 and 11.0 of the solution sprayed within the containment after a [
design basis accident.
The pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion crtcking on the mechanical systems and components.
