'#. O. 57300, JOB E-5590 In response to IE Bulletin 79-14, dated July 2, 1979, we submit the l
following:
Fo r WM. H. ZDDtER NUCLEAR POWER STATION - UNIT 1, all Seismic Category I systems are being verified that the seismic analysis applies to the actu tl piping configuration as a part of the Zimmer Construction Program. Field inspections are performed on each system to verify pipe support design and location, embed-ments, attachments, and valve location and orientation. The architect-engineer, l
Sargent & Lundy, also verifies actual valve and valve operator weights by the use of certified vendor data.
The field inspection data, in the form of marked-up drawings, are for-I warded to Sargent & Lundy to assess the validity of the original system analysis.
This work is performed on a sub-system basis and is illustrated by " Attachment A", Status of Piping Analysis, which shows the sequence for piping calculations, review, and reanalysis, if required. Sargent & Lundy submits sub-system packages to the field office for their review and comment to cover the as-built conditions for piping and pipe supports. " Attachment B",
letter SLC-12875, is a typical trans-l mittal of a subsystem package.
i The field review and inspection of seismic pipe supports is governed by Construction Inspection Procedure MC-5, " Final Inspection of Pipo Supports".-
Attachment C. CGLE QA is responsible for audit and implementation of Procedure I
MC-5.
Installed supports which deviate from design drawings are reworked or Design modified to com 1"
