Do you do a crud burst during forced outages?  This depends on how long the forced outage .  Management decides on various factors ,RCS activity, work scope, duration of forced outage.

How long do you run your Crud Burst Cleanup for? - Various, normally based on when we can get to 0.05 uci/ml in our RCS. Last outage it too ~71 hours, previous outage ~70 +/- 24 hours. We run an RCP for our crud burst as well.

Do you do fuel cleaning?  We have only done it once it our history.

Do you do fuel cleaning every outage?  See above

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
