PORTABLE OCCURRENCE Initial Cendition TEc Unit I reactor was in hot standby for the HPCI/RCIC i investigation and repair effort when the site engineering ) staff was n o t. I f i e d that the axial supports for the 20" line between the 1E11-F006A-D valves are inadequate. b Nature of Occurrence { CIIIl c reviewing the as-builts submitted for the IE Bulletin e' 79-14 program the AE discovered that hangers IE11-RRRH-196 and i 1 Ell-bHRH-313 would not adequately support their loads during ) a design bases earthquake. The AE then informed the site of k this problem per PDCR 52M-054. \\ Iceediate Corrective Action

A design change request is being written to have the PDCR 4 implemented. These supports #111 be modified prior to the (o unit coming on line. Cause 3' The apparent cause is due to' a faulty design in which
