ATTACHhENT 3 ' Page 1 of 2 MISCELLAh*20US OBSERVATION FROM SHALL BORE WALKDOWN The following conditions outside the scope of CPPP-5 were observed during the walkdown effort.
- 1. Discrepancy between valve number shown on. BRP drawing and tag on valve in field. Some examples of this observation are:
A. Valve 2CH-453 per BRP-CH-1-AB-031 Rev. 12 is tagged as 2CH-458 in field. B. Valve ICC-043 per BRP-CC-1-AB-049 Rev. 13 is doubled tagged as ICC-045 and ICC-043 in field.
- 2. Incorrect close clearance gaps were observed.
A. CC-1-EC-020-002-5 Gap = 1/4" B. SW-1-SI-006-014-3 Gap = 1/4" C. CH-X-AB,024-019-3 Gap = 1/4" D. CS-1-RB-013A-024-2 Gap = 1/4"
- 3. GH-X-AB-043-003-3 elevation 875'-5" per GHH drawing should be 857'-5".
,4 . GHH-CC-X-AB-013 Rev. 2 -
An unidentified support exists between support 001 and the elbow. This support is not shown on the GHH drawing.
- 5. BRP-CS-1-SB-063 Rev. 5 -
Piping connection to boren tank TEX-XIMEBS-01 does not agree with field condition. Fittings exist but are not shown on the BRP drawing.
- 6. Pipe support drawing H-GH-X-AB-020-026-5 shows support installed on the 3/4" line. There is a reducing insert at the tee, consequently the location of the support is actually on the 2" portion of the line.
- 7. Pipe support FSI-1-2107-01-D-01-1Q2 Rev. CP-1 dated 6/3/85 - design changes made on Rev. CP-1 have not been installed in the field (previous revision of drawing is installed).
- 8. GKH-CS-1-AB-215 -
The drain line located below support 007 is supported with a 2-way (box type) support which is not shown on the GHH drawing. 01291-1545405-N1
Attachment 3 Page 2 -
- 9. Discrepancies between the revision level received from Document Control and the revision level shown in the HITS reports were identified. Some examples are:
A. GHH-CC-1-AB-054 Rev. 6 from DCC, Rev. CP-1 Per HITS. B. CHH-DO-1-DG-003A Rev. 11 from DCC, Rev. CP-1 per HITS. C. GHH-DD-1-AB-011 Rev. 5 from DCC, Rev. CP-1 per ifITS. D. GHH-CS-1-AB-227B Rev 4 from DCC, Rev. CP-1 per HITS.
- 10. CHH-CC-1-RB-051 -
Line is in contact with cable tray support betweens supports 007 and 008.
- 11. Configuration Control -
The configuration of the Class 5 piping that is within the boundary of the ASME stress analysis is usually not shown on the BRP drawings. Per conversation with TUGC0 Engineering personnel routing changes to this piping are made by CMC or DCA against composite drawings. These changes are reviewed by the G&H piping group but are not reviewed by the responsible stress analysts. Therefore, there i s. no assurance that the configuration used in the stress analysis still reflects the present installed configuration. Conse.quently, "this piping should be documented and controlled to the same degree as the ASME portion of the piping. Note: The Class 5 support locations are shown on the GHH drawings. Changes to GHH drawings are required to be reviewed by engineering. r l I 01291-1545405-N1
ATTACKMENT 4 Page 1 of 1 METHOD FOR OBTAINING VAINE LOCATION POPULATION The following method was used to determine total number of small bore valves associated with small bore ASME piping not subjected to the TUGC0 As-Built Program.
- 1. A list of small bore piping isometrics (BRP drawings) for the piping not subjected to TUGC0 As-Built program was generated using the small bore HITS (hanger information tracking -system) report.
This was achieved by sorting BRP drawings which are not associated with stress problems.
- 2. The record prints of these BRP drawings were reviewed. A list of all valves on the small bore piping was generated.
- 3. SkIC identified that portions of this small bore piping had been subjected to the As-Built program. Small bore valves which were included in the As-Built program, were deleted from the list generated in Item 2.

ATTACHMENT 5 Page 1 of 1 METHOD TO OBTAIN POPUI.ATION FOR VALVE AND SUPPORT ORIENTATION The following method was used to determine the total population for valve and support orientation attributes.
- 1. The two previously generated lists, one for support location (HITS Report) and one for valve location (Attachment 4) were used to determine the total population for valve and support orientation attributes. -
- 2. All the valve drawings for the valves in the list generated for valve location attributes were reviewed for extended valve .
operators.
- 3. A list of valves wf.th extended operators was generated and then combined with the list of all small bore supports.
