MARGIN from expected operating conditions of equivalent to that required by Figure 3.1-5 after xenon decay and cooldown to 200*F.
The maximum boration capability (minimum boration volume) requirement is established to conservatively bound expected operating conditions throughout core operating I
life.
The initial RCS boron concentration is based on a minimum expected hot i
full power or hot zero power condition (peak xenon).
The final RCS boron concentration assumes that the most reactive control rod is not inserted into l
the core.
This set of conditions requires a minimus usable volume of 21,802 gallons of 6300 ppm borated water from the boric acid storage tanks or 1
1,166,000 gallons of 2700 ppm borated water from the refueling water storage tank (RWST).
A minimum RWST volume of 1,166,000 gallons is specified to be consistent with ECCS requirement.
With the RCS temperature below 200*F, one Boron 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 changes in the event the single Boron Injection System becomes inoperable.
The limitation for a maximum of one centrifugal charging pump to be OPER-ABLE and the Surveillance Requirement to verify all charging pumps except the required OPERABLE pump to be inoperable below 350*F provides assurance that a mass addition pressure transient can be relieved by the operation of a single PORV.
The baron capability required below 200*F is sufficient to provide a SHUTDOWN MARGIN of 1.3% Ak/k after xenon decay and cooldown from 200*F to 140*F. This condition requires either a usable volume of 4100 gallons of 6300 ppm borated water from the boric acid storage tanks or 250,000 gallons of 2700 ppm borated water from the RWST:
The unusable volume in each boric acid storage tank is 1300 gallons.
The contained water volume limits include allowance for water not available because of discharge line location and other physical characteristics.
The lialts on contained water volume and boron concentration of the RWST also ensure a pH value of between 7.0 and 7.5 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 minimum RWST solution temperature for MODES 5 and 6 is based on analysis assumptions in addition to freeze protection considerations.
The i
minimum / maximum RWST solution temperrtures for MODES 1, 2, 3 and 4 are based l
l on analysis assumptions.
