A. After turnover contact CRS to perform power swap for Bus 17AC. (Event 1)
B. Using 04-1-01-R21-17, SOI for 17AC bus, the BOP will rotate power from ESF Transformer 12 to normal source of ESF 21.
Loss of Bus 17AC with a Division 3 Diesel Generator failure:
A. 30 seconds after power has been swapped on bus 17AC, incoming feeder 152-1705 will trip causing a loss of 17AC. Div 3 D/G will fail to start. (Event 2)
B. The crew will take the actions per Loss of AC Power ONEP by energizing the 17AC bus from an alternate feeder.
C. If sent to investigate 152-1705, as Electrical Maintenance wait 3 minutes then report problem is unknown and a work order is required.
D. The CRS will determine that TS 3.8.1 Condition B4 applies and require surveillance 06-OP-1R21-W-0001 Attachment II.
Loss of EPA Breaker on B RPS A. When the crew has addressed all required Tech Specs and/or at the direction of the lead evaluator, trigger Event 3 to cause EPA breaker C71-S003D to trip. (This is different from previous exams due to the failure of Electrical Protection Assemblies the RPS M/G will continue to run.)
B. The ATC will recognize and report a Division 2 half scram and determine a loss of B RPS.
C. The BOP will respond to the back panel area and determine a loss of power to the B RPS.
D. If sent to investigate loss of RPS B, wait 3 minutes and report C71-S003D has tripped on undervoltage.
E. CRS will enter the Loss of One or Both RPS Buses ONEP to transfer power to the alternate source.
F. The BOP will transfer B RPS power to alternate source G. The ATC will reset half scram H. The CRS will determine that TR 3.1.5 Condition A applies as long as the half scram is present.
