Presented December 8, 2016

2. Prairie State Unit 1 Online and operating well
Good Fall Run
One Tube Leak in mid-November (8-days)
Unit 2 online and operating well
Fall Outage
Started 4-days early due to tube leak
Outage ran longer than expected
High Weld rejection rates (10%) caused delay in outage. Moisture in Argon shielding and use of larger weld rods
Corrected weld issues and went back down to a typical 1-2% rejection rate
PSGC staff working to insure weld rejection rates do not reoccur at these high rates and tie reject rates into schedule impact
