PLANT SYSTEMS CONDENSATE STORAGE TANK LIMITING CONDITI'ON FOR OPERATION.

I l

3.7.1.3 The condensate storage tank (CST) shall be OPERABLE with a contained water level of at least 57%* (66%") {80%*"}.

l APPLICABILITY: MODES 1,2, and 3.

a.

Restore the CST to OPERABLE status 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 />, or b.

Demonstrate the OPERABILITY of the Essential Service Water System as a -

backup supply to the auxiliary feedwater pumps and restore the CST to -

OPERABLE status within 7 days 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 />.

SURVEILLANCE REQUIREMENTS 4.7.1.3.1 The CST shall be demonstrated OPERABLE 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 verifying the contained water level is within its limits when the tank is the supply source for the auxiliary feedwater pumps.

4.7.1.3.2 The Essential Service Water System shall be demonstrated OPERABLE 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 performing the surveillance specified in Specification 4.7.4a. whenever the Essential Service Water System is the supply source for the auxiliary feedwater pumps.

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) 3)

Verifying a system flow rate of 66,900 cfm i 10% through the train and 22,300 cfm *10% per bank through the exhaust filter plenum during operation when tested in accordance with ANSI N510-1980; and 4)

Verifying that with the system operating at a flow rate of 66.900 cfm 110% through the train and 22,300 cfm 110% per bank and exhausting through the HEPA filter and charcoal adsorbers, the total bypass flow of the system and the darper leakage is less than or equal to 1% when the system is tested by admitting cold DOP at the system intake and the damper leakage rate is determined by either direct measurements or pressure decay measurements at a test pressure of 2 inches of water and the auxiliary building exhaust fans are operating at their rated flow.

After every 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of charcoal adsorber operation, by verifying, c.

within 31 days after removal, that a laboratory analysis of a repre '

sentative carbon sample obtained from each bank of adsorbers of the

. train in accordance with Regulatory Position C.6.b of Regulatory Guide 1.52, Revision 2, March 1978, meets the laboratory testing cri-j teria of Regulatory Position C.6.a of Regulatory Guide 1.52, Revision 2, March 1978, when the average for a methyl iodide penetration of less than 1% when tested at a temperature of 30*C and a relative humidity of 70%.

d.

At least once per 18 months by:

j 1)

Verifying for each filter bank of the train that the pressure drop across the combined HEPA filters and charcoal adsorber banks of less than 6.0 inches Water Gauge while operating the exhaust filter plenum at a flow rate of 66,900 cfm + 10% through the 1

train and 22,300 cfm 110% per bank;

~

2)

Verifying that the exhaust filter plenum starts on manual initiation or Safety Injection test signal; and 3)

Verifying that the system maintains the ECCS equipment rooms at 4

a negative pressure of greater than or equal to 1/4 in. Water Gauge relative to the outside atmosphere during system operation while operating at a flow rate of 66,900 cfm 110% through the train and 22,300 cfm 110% per bank.

After each complete or partial replacement of a HEPA filter bank, by e.

verifying that the exhaust filter plenum satisfies the in place penetration testing acceptance criteria of less than 1% in accord-ance with ANSI N510-1980 for a DOP test aerosol while operating at a flow rate of 66,900 cfm + 10% through the train and 22,300 cfm 110%

per bank; and t
