10 CFR PARTS 50.55(e)  :

SUPPLEMENTAL TO FINAL REPORT' 1

i Cause , ,

The nature of the deficiency is such that an exact determination of

{

its cause is not possible. The deficiency was probably due to human '

error in the recording of heat numbers as the materials were logged [

} in. ,

?

I l Action to Prevent Recurrence }

t The appropriate personnel have been reinstructed in the need for j proper and accurate documentation of material heat numbers as i specified in Receiving Inspection Storage and Preventative  !

I Maintenance Procedure C-501 and in addition, Quality Control i

Information Prc

edure, QCI-C-301.Il has been revised (as underlined) j i to read: '

Prior to unloading the material, verify that the heat number '

on t.he (**VA Requisition Form) 575 is acceptable for use per <

the latest list of acceotable heat numbers. f

._ I This revision should prevent any material from entering the  ;

j warehouse which is not on Phipps Bend's lists of acceptable material  !

j heat numbers (heat number log). Therefore, regardless of the cause [

, of an improper log entry (be it human error or otherwise), the error }

would be detected by implementation of this procedure. ,
