3.

Leakage rates greater than 1.0 gpm but less than or equal to 5.0 gpm are unacceptable if the latest measured rate exceeded the rate determined by the previous test by an amount that reduces the margin between measured leakage rate and the maximum permissible rate of 5.0 gpm by 50% or greater.

Operational Guidance for Section 314.4 3/4.4.1 Reactor Coolant Loops and Coolant Circulation 1.

Cold Shutdown

- Loops Filled: The Reactor Coolant System loops are considered filled while in a Cold Shutdown condition when the following conditions are met:

A.

The RCS must have been filled and vented in accordance with 1-NOP-Ol.05 /

2-NOP-Ol.05, RCS Fill and Vent, (If the Unit was just removed from service, the fill and vent was performed during the preceding startup).

B.

The RCS is at an inventory level of greater than or equal to 30% pressurizer level as indicated on Ll-1103.

C.

The RCS is capable of being pressurized to greater than or equal to 70 psia (55 psig) within the allowed time from loss of cooling to initiation of core boiling as per Attachment 1 in 1-AOP-03.02 / 2-AOP-03.02 as indicated on PlC / P1 -1103 or PlC / P1 -1104.

D.

Both SG narrow range levels greater than 10%.

E.

The RCS has not been drained below 63 as indicated on the refueling level indicator LI-i 117-i since the last RCS fill and vent procedure was performed.

3/4.4.6.1 Leakage Detection Systems The Reactor Cavity Flow Monitoring System consists of the Weir Pit, the flowmeter (FR-07-3), and the associated alarms (N-35 (Unit 1) from FR-07-3 and N-46 (both Units) from LS-07-12). The function of the system is to detect a 1 gpm leak within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

2.

The Reactor Cavity Flow Monitoring System is considered fully operable when both an alarm function works and the flow indication is functional.

If either the alarm(s) or flow indication is out of service, the system is operable, but degraded subjected to the following compensatory actions:

A.

If the Rx Cavity Leakage High Alarm is out of service, initiate a DS 30 to ensure leakage flow rates per FR-07-3 are recorded hourly. Unit 1 would require both N-35 and N-46 to be declared OOS to require this action.

B.

If FR-07-3 is out of service, no exceptional contingency actions are required.

A.

For up to 30 days provided the following occurs:

1.

The Containment Atmosphere Radioactivity Monitor (particulate) remains operable.
