CONTAINMENT SYSTEMS t-3/4.6.2 DEPRESSURIZATION AND COOLING SYSTEMS CONTAINMENT OVENCH SPRAY SYSTEM LIMITING CONDITION FOR OPERATION -

i 3.6.2.1 Two independent Containment Quench Spray subsystems shall be OPERABLE. .

APPLICABillTY: MODES 1, 2, 3, and 4. ,

. ACTION:

With one Containment Quench Spray subsystem inoperable, restore the inoperable system to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> 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 COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE RE0VIREMENTS 4.6.2.1 Each Containment Quench Spray subsystem shall be demonstrated OPERABLE:

a. At least once per 31 days:

1) Verifying that each valve (manual, power-operated, or automatic) in the flow path that is not locked, sealed, or otherwise secured in position, is in its correct position; and

2) Verifying the temperature of the borated water in the refueling ,

water storage tank is between 40'F and 50*F.

l b. By verifying, that on recirculation flow, each pump develops a-  ;

differential pressure of greater than or equal to 114 psid when tested pursuant to Specification 4.0.5; ,

c. At least once per 18 months during shutdown, by:

g 1) Verifying that each automatic valve in the flow path actuates i to its correct position on a CDA test signal, and 1.

, 2) Verifying that each spray pump starts automatically on a CDA test signal,

d. At least once per 5 years by performing an air or smoke flow test through each spray header and verifying each spray nozzle is unobstructed.

SVRVEILLANCE RE0VIREMENTS 4.6.2.2 Each Recirculation Spray System shall be demonstrated OPERABLE:

a. At least ' once per 31 days by verifying that each valve (manual, power-operated, or automatic) in the flow path that is not locked. l sealed, or otherwise secured in position, is in its correct ,

position;

b. By verifying, that on recirculation flow, each pump develops a differential. pressure of greater than or equal to 130 psid when tested pursuant to Specification 4.0.5;

c. At least once per 18 months by verifying that on a CDA test signal,

, each recirculation spray pump starts automatically after a 660 20 I second delay;

d. At least once per 18 months during shutdown, by verifying that each automatic valve in the flow path actuates to its correct position on a CDA test signal; and

e. At least once per 5 years by performing an air or smoke flow test L through each spray header and verifying each spray nozzle is

unobstructed.

3/4.9 REFUELING OPERATIONS  !

i 3/4.9.I BORON CONCENTRATION LIMITING CONDITION FOR OPERATION L

l 3.9.1.1 The boron soncentration of all filled portions of the Reactor Coolant  !

System and the refueling canal shall be maintained uniform and sufficient to l

ensure that the more restrictive of the following reactivity conditions is j

' met; either: ,

L j

a. A K,7f of 0.95 or less, or j l' b.. A boron concentration of greater than cr equal to 2300 ppm. i L

APPLICABILITY: MODE 6.*

ACTION:

With the requirements of the above specification not satisfied, immediately j suspend all operations involving CORE ALTERATIONS or positive reactivity changes and initiate and continue boration at greater than or equal to 33 gpm .

l of a solution containing greater than or equal to 6300 ppm boron or its . I equivalent until K is reduced to less than or equal to 0.95 or the boron '

concentration is r$Nored to greater than or equal to 2300 ppm, whichever is the more restrictive. .

SURVEILLANCE RE0VIREMENTS 4.9.1.1.1 The more restrictive of the above two reactivity conditions shall be determined prior to:

L 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 within the reactor vessel.

4.9.1.1.2 The boron concentration of the Reactor Coolant System and the L refueling canal shall be determined by chemical analysis at least once per L 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. ,

4.9.1.1.3 Valve 3CHS-V305 shall be verified closed and locked at least once per 31 days. ,

• The reactor shall be maintained in MODE 6 whenever fuel is in the reactor vessel with the vessel head closure bolts less than fully tensioned or with the head removed.
