ACLS By letter dated Kay 24. 1972 Jersey Central Power & Light , , ,

Ccampany reported that the sore was operated threegh wyste z U, 1-B with a fuel bundle miseriented. The needing eerer une made in spite of independent shoeks by the grappts operator, the shif t supervisor and en easineer en the refweling beridge.

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.

based on sensurenaents et stack gas semples taken during
