________________________________
Do you do a crud burst during your refueling outage?  Yes a crud burst is utilized

Do you do a crud burst during forced outages?  This depends on how long the forced outage is and how long we will be down for.  We did not do one on our current forced outage.  We were only onlice for approx. 2 days.

How long do you run your Crud Burst Cleanup for? - on the schedule it is for 24 hours.  We run the cleanup with RCP's in service and there is a bio delay to ensure any hotspots are identified and flushed as necessary

Do you do fuel cleaning?  Callaway has not performed fuel cleaning for many refuels

Do you do fuel cleaning every outage?  See above
