Questions
- 1.
Does t*e 86.25% of 2400 V setpoint of your second level of voltage protection (attachment 2a) adequately pro~ect 480 V and 120 V class lE equipment? Response to item l indicates this setpoint is 0.913 PU.
Resolve the discrepancy.
- 2.
Per NRC guidelines 3 and gb, compare the effect of starting and running the largest non~class lE load on all class lE equipment with the required voltage range for nonnal operation of these loads (starters, contactors, motors, etc.). What is the duration of identified transient undervoltage conditions?
- 3.
As required by NRC guideline 9, CP should provide analysis and comparison of terminal voltages on all class TE loads (2300 V, 480 V, and lower voltage loads) for the worst case starting voltage and steady state running voltages.
The CP submittalsa,c,d do not include all of these values.
- 4.
Plant FSAR, Section 8.3.2.2 and single line diagram indicate
\\
three alternate sources of offsite power to class lE buses.
Reference 2 includes analysis only for one offsite source (startup transformer).
Separate analysis for the other two offsite sources (service transformer and station power transformer) is required.

As per reference e, *the generi~ fssue in reference b, is part of SEP topic VIII-1-A.
CP should, therefore, review the station power system for possible violation of GDC-17 as requested in reference b.
