AC Sources-Operating B 3.8.1 Brunswick Unit 1 B 3.8.1-20 Revision No. 88 BASES SURVEILLANCE recommendations of Safety Guide 9 (Ref. 5), Regulatory Guide 1.9 REQUIREMENTS (Ref. 11), and Regulatory Guide 1.137 (Ref. 12), as addressed in the (continued) UFSAR.

Where the SRs discussed herein specify voltage and frequency

tolerances, the following summary is applicable. The minimum steady

state output voltage of 3750 V is derived from the recommendations

found in Safety Guide 9 (Ref. 5) and bounds the minimum steady state

output voltage criteria of 3698 V associated with the 4.16 kV emergency

buses analyzed in the AC Auxiliary Elec trical Distribution System Study.

This value (3698 V) allows for voltage drop to the terminals of 4000 V

motors whose minimum operating voltage is specified as 3600 V. It also

allows for voltage drops to motors and other equipment down through the

480 V level where minimum operating voltage is also usually specified as

90% of name plate rating. The specified maximum steady state output

voltage of 4300 V ensures the maximum operating voltage at the safety

related 480 V substations is no more than the maximum rated steady

state voltage criteria for the 480 V motor control centers. The maximum

steady state output voltage was determined taking into consideration the

voltage drop between the DGs and the 4.16 kV emergency buses and a

5% voltage boost at the 480 V substation transformers. This maximum

steady state output voltage also ensures that for a lightly loaded

distribution system, the voltage at the terminals of 4000 V motors is no

more than the maximum rated steady state operating voltage. The

specified minimum and maximum frequencies of the DG are 58.8 Hz and

61.2 Hz, respectively. These values are equal to +/- 2% of the 60 Hz

nominal frequency and are derived from the recommendations found in

Safety Guide 9 (Ref. 5).

SR 3.8.1.1 This SR ensures proper circuit continuity for the offsite AC electrical

power supply to the onsite distribution network and availability of offsite

AC electrical power. The breaker alignment verifies that each breaker is

in its correct position to ensure that distribution buses and loads are

connected to their preferred power source and that appropriate

independence of offsite circuits is maintained. The 7 day Frequency is

adequate since breaker position is not likely to change without the

operator being aware of it and because its status is displayed in the

control room.
