5 Page 1 of 1 POPULATION NAME: Large Bore Plpe Supports - Rigid PREPARED BY: ,^

I DATE: Julv 30, 1985 RESPONSIBLE QA/QC SUPPORT ENGINEER REV* L POPUI[ATIONSLISTSOURCE:

j The Hanger Installation Tracking System, commonly known as " HITS" is the source document for this population. The HITS program is a computerized

report which contains information for all supports (i.e., Small Bore and i

Large Bore) as to the system, unit, building, room number, support mark i

number and safety class. In addition, data pertaining to pipe size,

, integral attachments and construction status is provided.

i From the entire HITS program, a listing of Rigid Large Bore Pipe Supports was segregated out for only supports which are safety related, construction complete and QC accepted. Attachment 2 lists supports that make up the Large Bore Pipe Supports - Rigid population. A correction was made on page 582 of Attachment 2. regarding one of the Random Samples.

BASIS FOR ACCEPTING THE LIST: (Refer to Attachment 1) e Acceptance of the list is based on random sample verification of the entire

( HITS program content utilizing a separate source for both safety and

non-safety related supports. The separate source was a listing of Brown and Root Hanger Location (BRHL) Drawings. Once the BRHL Drawing Sample was established, all supports contained on the sample drawings were checked against HITS to verify completeness as to total support listings. An additional check was performed to verify the accuracy of support construction status. It was established that the Hanger Mark Number and Construction Status Content of the HITS program was accurate and could be

) used as a source for Large Bore Pipe Supports population.

) BASIS FOR ACCEPTING ANY ADDITIONAL ITEMS: Not Applicable 3

, ATTACHMENT 1 POPULATION SOURCE VERIFICATION PROCEDURE FOR LARGE AND SMALL BORE PIPE SUPPORTS 1.0 PURPOSE This procedure delineates the verification of the source document and related input data. The objective is to verify, with a high level of j

confidence, that all supports which are safety related, work completed, inspected and accepted by QC at Comanche Peak Steam Electric Station (CPSES) Units 1, 2 and common are listed on the source document.

2.0 METHOD 2.1 Background .

The Hanger Installation Tracking System (HITS) is used by all construction site personnel for inputing and updating i' formation related to pipe supports. This inputing is done on a /.aily basis i

through manual means and turned in for computer update prior to shif t j end. Input is checked against output for accuracy.

l

, . The CPRT QA/QC discipline engineers concluded the HITS program would be used as the source for the population items list.

The completeness of the source document (HITS) has to be verified.

@ Due to the large number of supports, a statistical sample based on a source separate from HITS will be used for verification.

Large bore (rigid and non-rigid) and small bore safety related pipe supports are segments of HITS. To ensure that these segmente are complete, the entire HITS program (both safety and non-safety related) shall be checked.

Af ter establishing the validity and accuracy of HITS, those segments required for support populations will be segregated.

I 2.2 Source Verification 2.2.1 A listing of Brown & Root Hanger Location (BRHL) drawings l shall be obtained. From this listing, a random sample of 60 drawings shall be selected using the random digit tables "A Million Random Digita" by the Rand Corporation.

2.2.2 The supports shown on the randomly selected BRHL drawings shall be checked against the HITS output to ensure that the mark numbers appear for those supports. This check provides the confidence necessary that the HITS program contains a total listing of all supports and can be used as a basis for defining the populations.

ATTACHMENT 1 l

i i 2.2.3 The accuracy of the status of'each support requires an I

additional check to be made. The HITS program contains a Task Force (TF) column which is meant to indicate current support construction status. The accuracy of the column shall be checked by using all those supports from 2.2.1 and

.' verifying that the HITS output reflects the actual status.

I l 3.0 RESULTS 3.1 From the listing of 2013 BREL drawings a random sample of 60 was

- obtained.

All supports from the random sample were manually checked against the output from the HITS program. In all cases it was found that the supports were listed in the active, voided or deleted files of the HITS program.

l The listing of supports from the 60 drawings was then used to check the accuracy of the Task Force (TF) column in HITS. The status of each support was manually checked against records in the various vaults and processing areas as indicated on HITS. Again, in every l case, the status of each support as indicated in HITS matched that of the physical record location.

4.0 CONCLUSION

S I 4.1 From the overall sampling and review of documentation, records and

! computer program output, there exists a high degree of confidence that the HITS program can be considered a viable source for population lists and item status therein.

4.2 Basing the verification on the entire HITS program rather than just safety related, QC accepted items allowed an unbiased approach to be made. This approach makes it possible to draw our source from a

, segment of the entire population.

Excluded Attributes The following attributes were considered for inclusion in the checklist but were subsequently excluded for the reasons presented.

1. Piping Plumbness The Piping Erection Specifications, 2323-MS-100 established a 2 inch  !

tolerance for the location of piping. It then establishes the pluabness based on the location of the pipe. Since pipe location is a l separate attribute, plumbness will automatically be included, i.e. if a horizontal line is improperly located it must be rejected and if the horizontal line is located properly the vertical line can not be out-of-plumb.

2. Screwed Joint Thread Engagement The Piping Erection Specification 2323-MS-100 requires that for screwed joints, clean threads of the proper length shall be cut on the pipe to ensure the drawing up' of a pressure tight joint. In order to ensure a pressure tight joint proper thread engagement is required.

However, because of the variation in thread cutting it is not possible to visually inspect for thread engagement.

3. Gradient Although the maximum amount of gradient is specified in specification 2323-MS-100 a deviation from this tolerance has no bearing en system operation because slight variations from exact level do net affect system flow characteristics, pipe stresses, operation, etc. L'here gradient is required it is specified as a minimum slope which is addressed under a separate attribute.

l 4. Vent, Drain, Instrument, and Sample Root Valve Location I'

Although the procedure generally requires the exact location of valves i

to be checked this requirement was not imposed for small valves such j

as vent, drain, instrument, and sample root isolation. These valves j are generally small and symmetric in design. A check of their orientation and linear distance from the main pipe' or flange is sufficient for location determination.
