Amendment No.125 I
NPF-73 3/4.5 EMERGENCY CORE COOLING SYSTEMS (ECCS)
ACCUMULATORS LIMITING CONDITION FOR OPERATION 3.5.1 Each Reactor Coolant System accumulator shall be OPERABLE with:
- a.
The isolation valve open,
- b.
Between 7532 and 7802 gallons of borated water,
- c.
Between 2300 and 2600 ppm of boron, and
- d.
A nitrogen cover-pressure of between 585 and 665 psig.
APPLICABILITY:
MODES 1, 2 and 3.*
ACTION:
- a.
With one accumulator inoperable, except as a result of a closed isolation valve, restore the inoperable accumulator to OPERABLE status within one hour or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
- b.
With one accumulator inoperable due to the isol-ation valve being closed, either immediately open the isolation valve or be in HOT STANDBY within one hour and be in HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
SURVEILLANCE REQUIREMENTS 4.5.1 Each accumulator shall be demonstrated OPERABLE:
- a.
At least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> by:
- 1.
Verifying, by the absence of alarms, the contained borated water volume and nitrogen cover-pressure in the tanks, and
- 2.
Verifying that each accumulator isolation valve is open.
- b.
At least once per 31 days and within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after each solution volume increase of greater than or equal to 1% of tank volume by verifying the boron concentration of the accumulator solution.

NPF-73 3/4.9 REFUELING OPERATIONS BORON CONCENTRATION LIMITING CONDITION FOR OPERATION 3.9.1 With the reactor vessel head unbolted or
- removed, the boron concentration of all filled portions of the Reactor Coolant System and the refueling canal shall be maintained uniform and sufficient to ensure that the more restrictive of the following reactivity conditions is met:
- a.
Either a Keff of 0.95 or less, which includes a
1% Ak/k conservative allowance for uncertainties, or
- b.
A boron concentration of greater than or equal to 2400
- ppm, which includes a 50 ppm conservative allowance for uncertainties.
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 and continue boration at S30 gpm of greater than or equal to 7000 ppm boric acid solution or-....
its equivalent until Keff is reduced to
< 0.95 or-.-the boron concentration is restored to
Ž 2400
- ppm, whichever is the more-restrictive.
The provisions of Specification 3.0.3 are not applicable.
SURVEILLANCE REQUIREMENTS 4.9.1.1 The more restrictive 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 control rod in excess of 3 feet from its fully inserted position.
4.9.1.2 The boron concentration of the Reactor Coolant System and the refueling canal shall be determined by chemical analysis at least 3
times per 7
days with a maximum time interval between samples of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
(1) The reactor shall be maintained in MODE 6 when the reactor vessel head is unbolted or removed.
