Re[2]: Exercise scenarios vs. reality

["Neil, David M" <NEILDM@inel.gov>]

     If the safety analysis was properly done, the possibility of that bolt
     or its like falling during a lift had been assessed.  The margin of
     criticality safety for it falling on a spent fuel rack, and for any
     deformations it could cause, was acceptable, or it would not have been
     allowed to overpass them.

     At least that's the way it's done here.

Hi Jim,  Thank you for your comments.  A few years ago a sling broke when a
heavy bolt (3" dia if I recall correctly) fell into the spent fuel pool.   The
bolt had been stored there and I  am not sure of all the details.  If this
bolt had fallen on spent fuel racks, could criticallity have occured?     What
would have been the consequences in the spent fuel building?  What about areas
adjacent to the building?   I would appreciate the insight from other
radsafers.
