5.0 CONSIDERATIONS FOR PRESSURE TESTI ;0
1.0 INTRODUCTION
This procedure provides the criteria for the fabricat' ion and install-ation of ASME III, Subsection NF, Classes 1, 2, and 3 component sup-ports. Moment restraints are not within the scope of this procedure.
2.0 GENERAL 2 '.1 MATERIAL 2.1.1 Material Control Materials used in the fabrication of NF supports shall be materials acceptable for ASME use and do not necessarily include all materials acceptable for "Q" applications. Evidence of material acceptability g including shim material, will be provided through the use of a Sbteria_1 Identification Log (Attachment 1).
The log shall be completed by the-craft based on the information provided in the Ranger Packare. The log shall then be presented to QC for material verification _and_ signa.-
ture.
NOTE: Heat numbers shall be recorded for Class 1 and for_igpac1 tested support materials.
Welding material shall be controlled in accordance with CPM 6.9B.
2.1.2 Material Identification Prior to cutting, the heat or identification (MIC, co_de,.etc.)_nunker shall be transferred by mechanical marking, and this marking shall remain distinguishable throughout the fabrication process. When mechanical markings on the parts are not possible, such as on all-thread rods, the markings may be applied to bands or labels which are applied to the parts. The transfer of the markings shall be verified by QC prior to division. This verification is documented on the MIL.
Additionally, the support assembly shall be mechanically identified with the hanger mark number which shall remain distinguish-able throughout the installation.

JOB 35-1195 CP-CPM 9.10 11 n1/11/pa 3 of 17 Prior to division _of a bundle of bulk material _,_each piece of material shall be identified with a heat number. A heat code and purchase order number may be used instead of a heat number. Prior to division of the bundle, QC shall be notified so that the markings may be veri-fied and documented in accordance with *the applicable QA procedures.
NOTE: Materials used for some welded attachments will require impact testing. The need for impact tested materials will be speci-fied on the engineering drawing. Where possible, the vendor supplied attachment materials should be used. Otherwise, impact tested materials shall be requested when specified on the drawings.
When design reflects a total change of hanger number but does not physically alter the support, Welding Engineering will issue a modifi-cation MWDC whose only holdpoint will be Operation #1, " Support Number Identification". This will allow craft to change the number on the hanger with QC Inspector verification, per the design change.
2.1.3 Protective Coating Traceability All shop coated steel that requires protective coating and is cited for installation in the Reactor Building shall be stamped with a unique coating code number.
Unique code numbers shall be assigned and applied in accordance with CCP-30 and CCP-30A.
Upon division of materials, unique coating code _ numbers shall be transferred along with other unique material identification numbers.
The transfer of unique coating code numbers shall be witnessed by OC.
The transfer of coating code numbers is necessary only to steel that is cited for installation in the Reactor BuildinJ.
Additionally, upon division of material, any Q-coated steel that remains in stock shall maintain its coating code number.
If coating code number transfer.is necessary to accomplish this, it shal'. be witnessed by QC.

2.1.4 Fabrication of Parts T if 1l Parts for a support, e.g. base plates, structural members, etc..
may be fabricated without a dcawing or Hanger Package orovided they are described on the MIL and verified by QC as required by 2.1.1.
However, when the parts are being assembled into a support, the Hanger Package shall be intact unless the MIL must be removed 9
to fabricate another part.

3.1 RANGER PACKAGES
/
3.1.1 Fabrication / installation of component supports will be in accordance with the Hanger Package for supports. The package will consist of the BRH drawing (or a " typical" for 2" and under hangers), the Material Identification Log (MIL), the Weld Data Card (WDC), and the Weld Filler Material Log (WFML), where welding is required, for each nanger. vesign Unanges, such as CMC's affecting the hangers may be issued directly to the Hanger Package for inclusion and the CMC number recorded on the WDC.
The Ranger Package shall then be returned tU-~
Welding Engineering for review of the CMC to determine if the Weld Data Card requires modification or revision.
In those cases where a modification of the Weld Data Card is required, Welding Engineering will determine the extent of the work necessary to complete the hanger in accordance with the new design and a description of the necessary activities will be entered on the back of the Multiple Weld Data Card in the space provided for this purpose.
3.1.2 Weld numbers shall be assigned by Welding Engineering in the packages for the following weld categories:
1.
Welds to pressure retaining members.
2.
Full penetration welds except flare bevel on structural tubing.
3.
Hangers with multiple processes or multi-filler materials.
4.
Welds requiring NDE, other than visual.
5.
All Class i support welds.
3.1.3 Welding documentation shall be prepared in accordance with CPM 6.9G.
3.1.4 Upon completion of the hanger, the craft shall return the Hanger Package to Welding Engineering for final review. After final re-view, the Hanger Package will be returned to the craf t for final inspection by QC and subsequent transmittal by QES of the Hanger Package to the Permanent Plant Records Vault.
3.1.5 If modification or redesign of a hanger, which is inspected and filed in the Permanent Plant Records Vault, is necessary, the craft may cut any welds required by authority on an " Inspected Item Removal Notice" in accordance with CPM 6.10.
No re-welding may be done without issuance of the modified or redesigned Hanger Package.
3.1.6 If Welding Engineering receives drawing revisions or design changes to Hanger Packages which have already been accepted by QC, those drawings or design changes will be transmitted to the Quality Engineering Systems group.

The responsible foreman shall make this determination based on the NCR, CMC or the items' physical condition, as appropriate.
When Code stamped items or partial assemblies are modified, documentation for such modification shall be prepared as required by Appendix CPM 6.9G, and the modification accomplished accordingly.
Material supplied by ITT or NPSI, or B&R bulk stock may be salvaged Tor use in Glass 2 or 3 systems provided traceability _1p_ma.iDtained as follows:
1.
ITT - the alpha / numerical code identifying the material to a particular material specification and/or grade (i.e., the code "L7" identifies SA-320 Crade L7 material).
2.
NPSI - items identified with N-prefixed or N-suf fixed MIC number.
3.
B&R bulk stock - B&R procured ASME-related materials shall be maintained by heat number. Such stock designated for non-Q applications may be salvaged for Code use provided heat nushat traceability is maintained and is acceptable for Code _use.,
NOTE 1: When salvaging variable springs for use on a support other than where originally designated, the responsible personnel shall ensure that the correct size spring is used. If the load setting is to be readjusted, the original load setting mark on the face plate shall be obliterated by stamping directly over it with the letter "S".
NOTE 2:
Except as permitted above, hanger parts shall be used on hangers where designated and shall not be interchanged.
Material supplied in class 1 may be salvaged for used on class 1, systems provided the item's serial number or heat _, trac,eability.,

Where such attachment welds are removed, the Project Welding Engineer shall be notified. The Project Welding Engineer shall initiate a Weld Data Card or a Repair Process Sheet, as appropriate, requiring liquid penetrant and ultrasonic thickness inspection of the affected areas.
Attachments of any kind to the pressure retaining boundary of systems or components which have been turned over, shall not be removed unless authorized by a SWA, even if authorized by Engineering. This includes valve actuators, retaining plates, etc.
