3/4.1.1.4 MINIMUM TEMPERATURE FOR CRITICALITY 1
This specification ensures that the reactor will not be made critical with the Reactor Coolant System cold leg temperature less than 520'F. This limita-j tion is required to ensure (1) the moderator temperature coefficient is within its analyzed temperature range, (2) the protective instrumentation is within i
its normal operating range, (3) the pressurizer is capable of being in an OPERABLE status with a steam bubble, (4) the reactor pressure vessel is above its minimum RT temperature, and (5) the ECCS analysis remains valid for the
{! -
peak linear heat rate of Specification 3.2.1.
)
NDT l
j 3/4.1.2 80 RATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation.
The components required to i
perform this function include (1) borated water sources, (2) charging pumps, (3) separate flow paths, (4) boric acid makeup pumps,.(5) associated heat trac-ing systems, and (6) an emergency power supply from OPERABLE diesel generators.
With the RCS average temperature above 200*F, a minimum of two separate l
and reaundant boron injection systems are provided to ensure single functional i
capability in the event an assumed failure renders one of the systems inoper-i able. Allowable out-of-service periods ensure that minor component repair or corrective action may be completed without undue risk to overall facility safety from injection system failures during the repair period.
The boration capability of either system is sufficient to provide a SHUT-l DOWN MARGIN from expected operating conditions of 2.05 delta k/k after xenon i
decay and cooldown to 200*F. The maximum expected boration capability require-i ment occurs at E0L from full power equilibrium xenon conditions assuming the most reactive CEA stuck out of the core and requires boric acid solution from l
the boric acid makeup tanks in the allowable concentrations and volumes of i
Specification 3.1.2.8 plus approximately 19,000 gallons of 1720 ppe borated water from the refueling water storage pool or approximately 58,000 gallons of I
1720 ppe borated water from the refueling water storage pool alone. The higher l
limit of 447,100 gallons is specified to be consistent with Specification 3.5.4 in order to meet the ECCS requirements.
With the RCS temperature below 200*F one injection system is acceptable without single failure consideration on the basis of the stable reactivity con-dition of the reactor and the additional restrictions prohibiting CORE ALTERA-TIONS and positive reactivity changes in the event the single injection system i
becomes inoperable.
4 The boron capability required below 200*F is based upon providing a 2%
j delta k/k SHUTDOWN MARGIN after xenon decay and cooldown from 200*F to 140'F.
This condition requires either 5,465 gallons of 1720 ppe borated water from the refueling water storage pool or boric <.cid solution from the boric acid makeup tanks in accordance with the requirements of Specification 3.1.2.7.

With the RCS temperature below 200 F one 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 injection system becomes inoperable.
The boron capability required below 200 F is based upon providing a 2% delta k/k SHUTDOWN MARGIN after xenon decay and cooldown from 200F to 140F. This condition requires either 5,465 gallons of 2050 ppm borated water from the refueling water storage pool or boric acid solution from the l
boric acid makeup tanks in accordance with the requirements of Specification 3.1.2.7.

LIMITING CONDITION FOR OPERATION i
3.9.1 With the reactor vessel head closure bolts less than fully tensioned or with the head removed, the boron concentration of all filled portions of the Reactor Coolant System and the refueling canal shall be i
maintained uniform and sufficient to ensure that the more restrictive of the reactivity conditions specified in the COLR is met:
APPLICABILITY: MODE 6*.
ACTION:
With the requirements of the above specification not satisfied, immediately suspend all operations involving CORE ALTERATIONS or positive reactivity changes and initiate action to restore boron i
concentration to within COLR limits.
SURVEILLANCE REQUIREMENTS 4.9.1.1 The more res'.rictive of the above two reactivity conditions shall be determined prior to:
- a. Removing or unbolting the reactor vessel head, and
- b. Withdrawal of any full-length CEA in excess of 3 feet from its fully inserted position within the reactor pressure vessel.
4.9.1.2 The boron concentration of the Reactor Coolant System and the refueling canal shall be f
determined by chemical analysis at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
