This attachment is associated with Design Analysis 4525-2 "Adequacv of Electric Svstem Voltages" Rev 1.
The results of an additional LOCA voltage simulation is presented in this attachment.
Xn particular, case EOF LOCA was repeated with breaker 12BY opened.
This new case (EOF LOC4) quantifies the performance of circuit 767 during a
I.OCA condition when the offsite power system is configured in the normal 50/50 configuration and the grid voltage is at its minimum value of 116Kv.
Xt was not necessary to quantify the performance of circuit 751 for this condition since a
more limiting case (DOF LOCA) gives acceptable results.
2.0 Results For the EOF LOC4 case, 480 volt bus voltages, including the 1E buses, remain above 414 volts.
The lowest 480 bus voltage is 431.5 on Bus 16.
The voltages at motor terminals 16S and 16C are 429 and 430.5 respectively.
The lowest I'ICC voltage is 421.9 on ICC 1D.
The lowest 4160 bus voltage for the EOF LOC4 case was 3964 on Bus 12B which is well above the 3600 volt limit.
3.0 Conclusion The EOF LOC4 case demonstrates that circuit 767 will be able
'o maintain adequate voltages during LOCA conditions for the normal 50/'50 configuration even during worst case grid voltage conditions.
