Nozzle ID R -E-11A-161R 1-RC-E-118-16IR 1-RC-E-11C-161R 1-RC-E-110-161R 1-RC-E-11C-111R F.

Request for Relief IR-5: Relief is requested from performing a 100% volumetric examination on seven 6-inch Code Class 2 branch connection welds due to pemanent obstructions that restrict volumetric examinations.

It is noted that neither 83S83 Examination Category C-F, Item C5.30, nor the alternative rules of Code Case N-408, Examination Category C-F-2. Item C5.81, require volumetric examinations of these branch connections.

Based on the above, provide additional information with regards to why relief is requested for these welds, l

G.

General Coment:

The proposed alternative examinations and justifications, used by the Licensee for all requests for relief, are based on the subjet.t welds having received ASME Code Section III volumetric examinations and hydrostratic tests.

Examinations performed during construction ensure the structural integrity during PSI and initial operation.

The results from the

PS! provide baseline information that may indicate the expected i

extent of inservice examinations.

Inservice inspections are intended to detect service-induced degradation.
