The bundle was rotated 90' esenterclockwise from (to proper position, but a shock of the operating patters el a nearby control rod indleates that the foal bendte had i

no apparent offact.

A 900 minoriented bundle was analysed in the F8AAl peak heat fluxes were calculated to be far beloe feel damage limit.

No ACRS action is recommended.
