5' COMANCHE PEAK RESPONSE TEAM POPULATION DESCRIPTION Page 1 of 1 POPULATION NAME: Larne Bore Pipe Welds / Material l
PREPARED BY.t- --2,rM^Mdw YM/d5 DATE: September 25, 1985
' assr0NSIBLE QA#qc SUPPORT ENGINEER REV: 1 SYSTEM, COi@vur.nis, AND STRiiuunES:
The population includes:
For safety related systems identified on Attachment A Safety related site-made velds with nominal pipe diameter 21s inches and larger.
Safety related weld material and material of items associated with the
Safety related branch process connection site-made welds, weld
- material, and associated material, for 2 inch and smaller connections.
Site-made welds, weld asterial, and associated material for abandoned pipe support integral attachments.
Site-made welds on mechanical (integral flued head forging or spare end cap to the penetration sleeve weld) and electrical (weld neck flange to penetration sleeve weld) reactor containment penetrations. ,
POPULATION BOUNDARY:
Welds in the population (Unit 1 and Common, and Unit 2) which
- are installation complete and Qualit.y Control (QC) accepted.
Piping Welds in the population that are shown (numbered) on Brown and Root, Inc., piping isometrics which have been developed for safety related piping systems.
Penetration welds (portion considered part of pressure boundary) in the population that are shown as field welds on Brown and Root, Inc.,
piping drawings which have been developed for safety related systems / components.
SPECIFIC INTERFACES:
The population shall not include:
Welds for pipe support integral attachments to pressure retaining components. These are included in the populations for "Large Bore Pipe Supports (Rigid; Non-Rigid)".
2 inch and smaller pipe weld material and material of items associated with welds other than branch connections on large bore pipe. These are included in the population for "Small Bore Pipe and Instrument Pipe / Tube Welds / Material".
Piping configuration. This is included in the "Large Bore Piping Configuration" population.
Penetration welds to liner. These are included in the populations for
" Liners".
