REACTIVITY CONTROL SYSTEMS BORATED WATER SOURCES

COOK NUCLEAR PLANT - UNIT 2 3/4 1-16 AMENDMENT NO. N XN, 148
3 4.1 REACTIVITY CONTROL SYSTEMS BASES With the RCS average temperature above 200 F, a minimum of two separate and 0
redundant boron in)ection systems are provided to ensure single functional
- capability in the event an assumed failure renders one of the systems inoperable.
Allowable out-of-service periods ensure that minor component repair or corrective action may be completed without undue risk to overall facility safety from in5ection system failures during the repair period.
The limitation for maximum of one centrifugal charging pump to be OPERABLE and the Surveillance Requirement to verify all charging pumps and safety in)ectiono
- pumps, except the required OPERABLE charging pump, to be inoperable below 152 F, unless the reactor vessel head is removed, provides assurance that a mass addition pressure transient can be relieved by the operation of a single PORV.
The boration capability of either system is sufficient to provide the required SHUTDOWN MARGIN from expected operating conditions after xenon decay and cooldown to 200 F.
The maximum expected boration capability usable volume 0
requirement is 4905 gallons of 20,000 ppm borated water from the bozic acid storage tanks or 69,215 gallons of borated water from the refueling water storage tank.
The required RWST volume is based on an assumed boron concentration of 2400 ppm.
The minimum RWST boron concentzation zequired the the post-LOCA long-term cooling analysis is 2400 ppm.
The minimum contained RWST volume is based on ECCS considerations.
See Section B 3/4.5.5.
The boration source volume from the boric acid storage tanks has conservatively been increased to 5650 gallons.
This value was chosen to be consistent with Unit 1.
With the RCS average temperature below 200 F, one in)ection system is acceptable 0
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 change in the event the single injection system becomes inoperable.
The boron capability required below 200 F is sufficient to provide the required 0
MODE 5 SHUTDOWN MARGIN after xenon decay and cooldown from 200 F to 140 F.
This 0
0 condition requires usable volumes of either 298 gallons of 20,000 ppm bozated water from the boric acid storage tanks or 2408 gallons of borated water from the refueling water storage tank.
The boration source volumes oi Technical Specification 3.1.2.7 have been conservatively increased to 4300 gallons from the boric acid storage tanks and 90,000 gallons from the refueling water storage tank.
These volumes are based on conservative calculations performed foz Cycle 6 oi Unit 2.
The calculations assumed a final MODE 6 RCS boron concentration of 2000 ppm.
The limits on contained water volume and boron concentration of the RWST also ensure a pH value of between 7.6 and 9.5 for the solution recirculated within containment after a LOCA.
This pH band minimizes the evolution of iodine and minimires the effect of. chloride and caustic stress corrosion on mechanical systems and components.
The OPERABILITY of boron in5ection system during REFUELING ensures that this system is available for reactivity control while in MODE 6.
