EDG LOPS B 3.3.8 BASES ACTIONS C.d 1
(continued)
I Condition C is the default Condition should Required Action A.1 or B.1 not be met within the associated Completion Time.
Required Action C.1 ensures that Required Actions for affected diesel generator inoperabilities are initiated.
Depending on MODE, the Actions specified in LCO 3.8.1, "AC Sources-Operating," or LCO 3.8.2, are required to be entered immediate y.
1 SURVEILLANCE 1R 3.3.8.1 REQUIREMENTS l
A CHANNEL FUNCTIONAL TEST is performed on each required EDG LOPS channel to ensure the entire channel will perform the intended function. This test ensures functionality of each channel to output relays.
The Frequency of 31 days is considered reasonable based on the reliability of the components-and on operating experience.
A temporary extension of the frequency has been made to indicate "31 days or 60 days" as the frequency. This temporary condition applies-to a.one-time performance of the surveillance on each diesel generator and will not be effective after November 23, 1997.- The need for this temporary extension of the frequency became evident during replacement of the radiator on the EDGs.
This activity had a minimum duration of 42 days, which was in excess of-the 31-day frequency. Performance of the surveillance on one EDG with the other EDG inoperable because of the radiator replacement was considered as not the safest and most prudent course of action. A note has been added to the frequency to indicate that the 60-day frequency is not effective. after November 23, 1997.
A Note has been added to allow performance of the SR without taking the ACTIONS for an inoperable instrumentation channel' although during this time period the relay instrumentation cannot-initiate a diesel start. This allowance is based on the assumption that-4 hours is the average time required to perform channel Surveillance. The 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> testing allowance does not significantly reduce the availability of the-EDG.

EDti LOPS B 3.3.8
'(
BASES SURVEILLANCE REQUIREMENTS A CHANNEL CALIBRATION is a complete check of the instrument channel, including the sensor. The setpoints and the response to a loss of voltage and a degraded voltage test shall include a single point verification that the trip occurs within the required delay time, as shown in Reference 2.
The 18 month Frequency is based on operating experience and industry-accepted practice.
A Note has been added indicating the voltage sensing device (bus potential transformer since these transformers ar)e passive, inherently stablemay be exc devices which cannot be calibrated.
In the event of l
transformer failure, the corresponding degraded voltage or
. loss of voltage relays would trip on low voltage, actuating the associated channel condition. In addition,(i.e., the channels fail in the safe transforme)r or associated circuits would be provided via theannu l
channel monitor relay, identifying to-the operator a failure 1
within the loss of voltage or degraded voltage channels.
