Attachment to LER 79-015/01X-1 Rochester Gas and Electric Corporation R.E.Ginna Nuclear Power Plant, Unit No.1 Docket No.50-244 During the piping system inspections for the 30 day report required by IE Bulletin No.79-14, 10 pipe supports were determined to be in non-conformance with design requirements.

These supports were located on the containment spray (CS), residual heat removal (RHR), and service water (SW)systems.The following is a listing of the supports and nonconformances (NCR's G-79-88 through G-79-93 and G-79-95 through G-79-97): CS-53 one less support installed on lower containment spray ring than shown on drawing CS-235 pipe clamp not installed on lower containment spray ring at 235 location as shown on drawing 0 CS-295 pipe clamp not installed on lower containment spray ring at 295 location as shown on drawing 0 CS-12 RH-16 SW-3 U-bolt not installed as required by drawing pipe clamp not installed as required by drawing pipe support not installed at location required by drawing SW-20 SW-22 SW-23 SW-29 six U-bolts not installed as required by drawing four U-bolts not installed as required by drawing pipe clamp not installed as required by drawing pipe support not installed at location required by drawing Supports CS-235, CS-295, CS-12, RH-16, SW-3, SW-22, SW-23 and SW-29 have been reworked in accordance with the drawing requirements.

An engineering evaluation of the nonconformance identified on CS-53 deter-mined that the existing installation was adequate to assure performance of its intended function.Reinspection of support SW-20 showed that the non-conformance had been incorrectly reported;and it was in fact installed correctly.

)2.The corrective actions described above have been completed.

It is our conclusion that the nonconformances are a result of a lack of documented approvals for field changes and nonconformances during original plant con-struction.

Additional inspections as required by IE Bulletin No.79-14 were per-formed, and the results are provided in our 60 day, 120 day, and final responses.
