1. BRIEF DESCRIPTION OF ICCN/CCN:

Purpose:

This ICCN supports PCN 561 and ECP 050500255-34. The ECP revises the setting for the 4-undervoltage relays 3A0420-127D-1, 3A0420-127D-2, 3A0420-127D-3, and 3A0420-127D-4.

This ICCN is to analyze for the expected 4 kV voltage at the early DGVSS window of 4.11 seconds after the lt loading sequence on a postulated switchyard voltage of 219.5 lcV.

Acceptance Criteria:

The calculated 4 kV voltage at the early DGVSS window of 4.11 seconds should be above the maximum design limit value of 4190 V (reference E4C-090, ICCN C-130). This will ensure that the 4 k-V bus remains connected to the normal preferred (offsite) source during the load sequencing when the unit experience a DBA.

Results and

Conclusions:

The resultant 3A04 bus voltage derived from this ICCN is 101.43% x 4160 = 4219.5 V at 4.11 seconds. This is above the acceptance criterion of 4190 V as decribed above, and is therefore acceptable.

3.0 ASSUMPTIONS

See the base calculation for overall assumptions. No additional assumptions are introduced in this ICCN.

4.0 DESIGN DATA:

4.14 Per calculations E4C-1 30 and E4C-090, degraded bus voltage relays 127D-1, 127D-2, 127D-3, and 127D-4 setting and maximum design limit are as follows:

Maximum Design Limit 4190 V Maximum Relay Pickup 4183.9 V

5.0 METHODOLOGY

5.11.1 These degraded bus voltage relays in conjunction with timing relays will initiate a degraded grid voltage signal with SIAS (DGVSS), which will transfer the 4.16 kV Class lE buses to the standby power source, during the first automatic load sequencing cycle only. If no degraded voltage is detected during the first automatic load sequencing cycle, timing relays will ensure that during subsequent load sequencing cycles no DGVSS will be generated. If the voltage is above the 27N maximum pickup voltage (4183.9 V) at 4.11 seconds, all the ESF loads will be sequenced onto the bus irrespective of the bus voltage during the subsequent cycles thus assuring no interruption in the middle of load sequencing. (reference DBD-S023-120 Figure D-I8 and EBD 32220 sht.2) 5.12 CASE I b.4 CASE I.B-A219 - This case considers a Unit 3 ESF bus alignment for Trains A, ESE bus is connected to the X-winding of their dedicated Reserve Auxiliary Transformer. A lumped load of 20 MVA is considered in the Y-winding per Section 3.1. A Design Basis Accident is postulated for Unit 3.

This case was established to verify the capability of the electrical auxiliary system of Unit 3 to start, based on a predetermined sequence, and operate all ESF loads that are required to mitigate the consequences of a Design Basis Accident (DBA) when served from the normal preferred power source. Loading sequence is based on Table 10.1, Case I.B-A-1.

The switchyard voltage used in this analysis is 219.5 kIV. This ICCN is to verify that the 4 kV bus voltage is above the maximum design limit voltage (4190 V) at 4.11 seconds.
