LOP Instrumentation 3.3.8.1 SURVEILLANCE REQUIREMENTS
-- A----------------
NOTES----------------
- 1.
Refer to Table 3.3.8.1-1 to determine which SRs apply for each LOP Function.
- 2.
When a 4.16 kV Emergency Bus Undervottage channel is placed in an inoperable status solely for performance of required Surveillances, entry Into associated Conditions and Required Actions may be delayed for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> provided the assIcaated Function maintains initiation capability (for Functions 1 and 2) and annunciation capability (for Function 3).
SURVEILLANCE FREQUENCY SR 3.3.8.1.1 Perform CHANNEL CHECK.
12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> SR 3.3.8.1.2 Perform CHANNEL FUNCTIONAL TEST.
31 days SR 3.3.8.1.3 Perform CHANNEL CALIBRATION.
18 months SR 3.3.8.1.4 Perform LOGIC SYSTEM FUNCTIONAL TEST.
24 months I
HATCH UNIT I 3.3-65 Amendment N~o. 243
LOP Instrumentation B 3.3.8.1 BASES SURVEILLANCE REQUIREMENTS SR 3.3.8.1.4 (continued)
The system functional testing performed in LCO 3.8.1 and LCO 3.8.2 overlaps this Surveillance to provide complete testing of the assumed safety functions.-
The 24 month Frequency Is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient If the Surveillance were performed -with-the-reactor at power. The 24 month frequency Is further based on a review of surveillance test history.
