FEB 021983 2 of 12 2.3 RESPONSIBILITY The QC Group Supervisor shall be responsible for the overall implementation of this procedure.

All inspection personnel performing inspections required by l

this procedure shall be trained, qualified and certified in i'

accordance with Reference 1-A.

The Quality Engineering (QE) Completions / Start-up Group Supervisor shall be responsible for supplying Quality Control with all the documentation required to perform piping system status walkdowns and component support design verifications.

3.0 PROCEDURE 3.1 PRERELEASE WALXDOWN p

The QC Systems Leads shall be responsible for performing a sJ status walkdown of piping systems.

1 I

Walkdown statusing of piping systems / subsystems shall be perfonned using the "QC Prerelease Checklist" (Attachment l

1), BRP drawings, vendor supplied subassembly drawings, BRH/GHH and SRHL's, if available, at the time of release.

l and all CMC'sl that have not been incorporated into the latest drawings.

If all drawinos are not available at time T l

of walkdown, that portion of the system which is affected by the missingi drawings will be statused when the drawings are received, i L

I i

The following :information shall be recorded on the system l

BRP drawing during prerelease walkdown:

i a.

Manufacturers identification / serial number of all ASME I

stamped items (i.e. piping subassemblies, valves, pumps and vessels), within the boundries of the BRP.

I b.

Material identification (i.e., Heat numbers, heat code, material specification) for material supplied by B&R, l

if available.

3.2 RELEASE FOR PENETRATION SEALING The Area Management Penetrations Seals Supervisor shall notify QC Systems Superintendent of piping penetrations they want released for sealing.

The QC Systems Lead shall verify the penetration meets the following acceptance requirements:

a.

All welds inside penetrations are completed, pressure tested and acceptable.

b.

No base material defects.

c.

Free of foreign material, d.

Hangers and permanent attachments required are installed and comply with design specifications, e.

Pipe clearance and gradient.

g The Completions / Start-up QC Group will notify Area Management of penetrations acceptable for sealing.

Prior to releasing a penetration for sealing, the Penetration Seal Release Form (Attachment 2) shall be completed and submitted to the ANI for his concurrence.

Completed Penetration Seal Release Forms shall be forwarded to Quality Engineering Systems (QES) for filing in the applicable line file (s).

3.3 COMPONENT SUPPORT DESIGN VERIFICATION The QC Systems Leads shall be. responsible for performing an inspection of all ASME Component Supports to verify they are in compliance with the Vendor Certified (Large Bore) or Design Reviewed (Small Bore) drawings.

Inspections of component supports shall be performed using the "QC Caponent Support Checklist" (Attachment 3).

Any welds on component supports that are not required by the Vendor Certified (VCD) or Design Reviewed Drawing shall be inspected in accordance with Reference 1-B.

The QC Inspector shall indicate on the VCD or Design Reviewed Drawing the actual weld size and its location..

i 3.4 SYSTEM / SUBSYSTEM DEFICIENCIES'

Base material defects and arc strikes shall be identified and resolved per Reference 1-C,*

in addition to being recorded on the "QC Punchlist".

When the prerelease walkdown is completed, the QC Systems clerks shall return all walkdown documentation and a copy of the QC Punchlist to the QE Completions / Start-up Group for coordinating resolution of punchlist. Items (Reference 1-0).

The QE Completions / Start-up Group shall notify the responsible QC Systems Leads when the QC Punchlist items have been corrected by returning their copy of the Punchlist and supporting documentation to the QC Systems clerks. The corrected items will be reinspected to verify acceptability per "QC Prerelease Checklist" or "QC Component Support Checklist" and a copy forwarded to QE Completions / Start-up Group.

Any unsatisfactory items that require an Engineering O

evaluatioa or re ork wiii be ideatified oa hca's ia accordance with Reference 1-C.

A system or portion of a system shall not be considered completed until Quality Assurance has verified through_ the above mentioned QC walkdown and QE Systems documentation review that all permanent piping, valves, pumps and hangers are comp 1'te and intact and have been installed in accordance e

with current installation documentation (i.e., BRP drawings, BRHL's,BRH's,GHH's, CMC's,etc.). Also the pressure! test shall have been completed and accepted by the ANI and the Owner in accordance with Reference 1-E.

other than pipe to pipe, a minimum of one inch shall be maintained, including pipe insulation. All other lines may be installed with a clecrance only for insulation; however, on a case by case basis it might be necessary to notch insulation to establish clearance which will require engineering approval.

17. When installed in bicckouts, sleeves shall be installed so that, for lines with

-O operating' temperatures at or above 200*F.

their centerlines are within 1/4 inch of piping centerlines. For lines with operating temperatures of less than 200*F, the sleeve inside diameter must be no less than 1/2 inch from pipe outside diameter.

18. All bolts installed in flanged connections.
