Mr. James G. Keppler Regional Director RE:
kM. H. ZIMMER NUCLEAR POWER STATION - UNIT 1 IE BULLETIN 79-14, DOCKET 50-358 W.O.
57300, JuB E-5590 In response to IE Bulletin 79-14, dated July 2, 1979, we submit the following:
For k?!. H. ZIMMER NUCLEAR POWER STATION - UNIT 1, all Seismic Category 1 systems are being verified that the seismic analysis applies to the actual piping configuration as a part of the Zimmer Construction Program. Field inspec ions are performed on each system to verify pipe support design and location, embed-ments, attachments, and valve location and orientation. The architect-engineer, 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-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-mittal of a subsystem package.
The field review and inspection of seismic pipe supports is governed by Construction Inspection Procedure MC-5, " Final Inspection of Pipe Supports",
Attachment C. CG&E QA is responsible for audit and implementation of Procedure MC-5.
Installed supports which deviate from design drawings are reworked or modified to comply with the specified design, or alternatively, a Design Document Change is processed and submitted to Sargent & Lundy.
Internal procedures within Sargent & Lundy for final piping analysis are governed by Project Instruction PI-ZI-13.1 titled " Finalizing Piping Anal-ysis, Hanger and Restraint Design, and Support Loading", Attachment D.
For illustrative purposes, please find copies of Sargent & Lundy internal trans-mittals which demonstrate the use of the referenced Project Instruction Pro-cedure for a typical subsystem:

Attachment E, March 2, 1979 memo from Mechanical Design and Draf ting (MD&D) to Engineering Mechanics (EMD) request-ing review of Design Document Changes M-8055 and M-9038 for subsystem RH-33.

Attachment F, March 23, 1979 memo from EMD to MD&D indicating that re-analysis is required for subsystem RH-33.
c.
Attachment G, April 23, 1979 memo from MD&D to EMD which transmits the computer program card deck and the piping analyt-ical drawings for reanalysis of sub-system RH-33.
We believe the information contained in this response illustrates that the Zimmer Project has an ongoing program to verify the seismic analysis of all safety related piping systems and thus addresses the concerns of IE Bulletin 79-14.

Dear Mr. Borgmann:
r u so.
This letter will confirm the following piping subsystem
~~
packages were hand-carried to Mr.
B.
K.
Culver by Mr. Desai of Sargent & Lundy on May 22, 1979:
HP-1 HP-3 HP-ll RI-20 The subsystem packages consist of the P&ID marked up defining the subsystem boundary, hanger drawings within the subsystem, design document changes written on the hangers, and piping system drawings marked up to show the boundaries of the subsystem.
The field should review the subsystems and verify that all the information reflects the as-built conditions so that the analysis can be certified as being complete and future iteration on piping analysis eliminated.
If analysis is required, it would only be performed one additional time.
Subsystem information which is not complete should be marked on the drawings for both hangers and piping changes so that we can use this to make only one final piping
- c. - m g s)t) $ YOL
SARGENT & LUNDY CNGlNCERS CHICAGO Mr.
E. A. Borgmann SLC-12875 The Cincinnati Gas & Electric Company May 22, 1979 Page 2 analysis prior to certifying the final stress report and hanger designs.
Hangers which are not installed should be reviewed for feasibility and space reserved in the location to preclude future interferences when hardware is delivered and installed.
Reanalysis on these systems will be held until the field confirms that the subsystem packages are complete and correct or comments returned to us to complete the package.
Your early response is required so that final drawing issue can be expedited.
Drawings would be expected to be issued approximately 12 weeks after receipt of your comments if reanalysis is necessary.
Yours very truly R. J. Pruski Project Manager RJP/mw In triplicate Copies:
