1.0 PURPOSE This instruction provides methods to be used and the accept / reject criteria to be applied in performing reinspections of instrumentation equipsent.

2.0 APPLICABILITY This instruction applies to the reinspection of samples selected from the instrumentation equipment population at Comanche Peak Units 1, 2 and areas common to both units. The population is discussed in the Population Description for Instrumentation Equipment.

3.0 REFERENCES

3.1 CPP-009, Performance of Reinspection and Documentation Review.

3.2 Description Memorandum QA/QC-RT-274, Rev. 1, dated 09/12/85 delineating documentation used in the development of this procedure including specific sources for attributes and exclusion.

4.0 GENERAL 4.1 Responsibilities

1. Responsibility for reinspection is set forth in Reference 3.1.

5.0 INSTRUCTION

, 5.1 Using the information in Reference 3.1 and below, perform the

! reinspection on the items in this population. Use the checklist to record the findings, see Attachment 6.1.

l i Measurements shall be made using standard inspection tools.

Attachment 6.3 provides a list of standard inspection tools and their corresponding codes. Record on Attachment 6.4 the tool code, serial number and calibration due date of the tool used to measure dimensions, where applicable.

1. Instrumentation Piping / Tubing and Components 1.1 Material Identification O

() 5.0 INSTRUCTION (Cont'd)

1. Instrumentation Piping / Tubing and Components (Cont'd)

Instrument Installation Detail drawing. For flanged connections, verify that the stud, nut and gasket materials are in accordance with the applicable drawings and/or supplemental

, instructions.

NOTES: 1. All tubing shall be clearly marked with longitudinal color coded marks for traceability. Use applicable drawing to identify tubing. All welded instrument valves are supplied with a minimum 6" tubing stub ends as part of the valve assembly. This portion of the tubing does not need any longitudinal marks since they are supplied with the valve.

2. If sealant is visible at a joint, it should be Never-Seez compound pure nickel, Neolube No. 2 (nuclear

(~'\ grade) or adhesive back grafoil tape

\s / (catalog #G-6255 and G-6303). The use of Rectorseal is prohibited in all areas. Teflon tape is also prohibited in all areas except the turbine generator building and the circulating water intake structure.

If teflon tape is identified where inappropriate, a Deviation Report should be initiated.

1.2 Piping / Tubing Size and Marking

a. Verify that the piping / tubing si=e agrees with the applicable design drawings.
b. Verify that the tubing associated with instruments annotated by on the tabulation sheetismarkedcircumfere(n)tiallyfor separation criteria at intervals not exceeding 10 feet and at points of entry to and exit from enclosed areas.

The colors for identification marking shall be as follows:

()

I Train A - Orange l Train B - Green i Channel I - Red Channel II - White Channel III - Blue Channel IV - Yellow 3

5.0 INSTRUCTION (Cont'd)

1. Instrumentation Piping / Tubing and Components (Cont'd) 1.3 Routing Verify that the tubing is connected from the sensing element to its associated receiving instrument such as transmitter,-switch, or indicator. Check tag numbers of instruments and proper hook-up of high/ low pressure connections for differential pressure instruments in accordance with the installation detail drawing.

1.4 Slope Verify that the installed tubing for wetted process lines has the proper slope to eliminate air po '-e'ing. The required slope for process wetted lines is 1/4 inch per foot minimum except when noted otherwise in the drawing.

Inspector shall provide actual slope measurement when it is less than 1/4 inch per O foot.

1.5 Air Gap Verify that there is proper air gap. The minimum gap spacing shall always be 1/8 inch to allow each instrument sensing lines to expand independently at all bends without striking adjacent sensing lines, other equipment, concrete or steel building members. The 1/8 inch minimum air gap requirement applies to the entire tubing run.

1.6 Separation Verify that the separation of the instrumentation sensing lines is maintained as required by the applicable drawings.

Where the separation group of a safety-related instrument is I, II, III, IV, A or B, and marked with a $ in the tabulation sheets then the instrument must be separated from its redundant counterpart. The minimum distance between safety-related redundant counterparts O is 18 inches in the horizontal and vertical direction between the closest parts of the respective instruments and/or sensing 4

QI-012 Rev. 1 A

5.0 INSTRUCTION (Cont'd)

1. Instrumentation Piping / Tubing and Components (Cont'd) lines. Safety-related instrument sensing lines of one channel should not directly come in contact with Class IE equipment of another redundant channel.

NOTE: The term " Redundant Counterparts" refers to 2 or more instruments assigned to different separation groups, used to measure or control the same, or similar j parameters.

1.7 System Bends

a. Verify that bends have a minimum of four (4) times the nominal tube size by using a template or the following procedure:

(1) Measure the bend angle (B) in degrees.

(2) Measure the outside are length of the

[h curved segment of the tube (L), in inches,

\-- corresponding to the bend angle.

(3) Divide above measured arc length by bend angle (L/B) and verify resultant values are equal or greater than the minimum

acceptable values provided in Attachment 6.2, Table A.

l (4) Enter measured and calculated values on Attachment 6.2. Initial and date each entry.

NOTES: 1. Vent and drain bends do not have to be verified for the four (4) diameter requirement since vents and drains are not subject to process systems pressures.

  • 2. Where a particular bend is inaccessible for measurement, the inspector shall identify the bend and note on the minimum radius bend f

form that it is inaccessible.

b. Verify that bends curve uniformly and have no

! visible crimps, kinks, or flattening.

i QI-012 Rev. 1 5.0 INSTRUCTION (Cont'd)

1. Instrumentation Piping / Tubing and Components (Cont'd) 1.8 Flex Hose Installation Verify that flex hose is installed without excessible twist being imposed. If the anti-torque indicator lines can be visually observed to be mis-aligned, condition is considered excessive twist.
2. Instruments 2.1 Instrument Identification Verify that the instrument tag number is correct in accordance with the applicable drawings.

2.2 Location Verify that the instrument location is in accordance with the applicable design drawings.

}

Floors and walls are acceptable reference points for instrument location verification.

Locally-mounted off-line instruments are to be installed with a 13 inches horizontal and a 14 inches vertical tolerance. External cage-type level devices shall be installed with a il/4 inch vertical tolerance.

2.3 Installation Verify that the instrument is installed in accordance with the applicable drawings. For differential pressure type instruments, verify the proper hook-up of high/ low pressure connections. Check vents / drains connections, if applicable.

2.4 Separation i

Verify that the separation of the instruments markedwithikonthetabulationsheetsis i maintained as required by the design drawings.

The minimum distance between safety-related j

() instruments is 18 edge-to-edge inches in the horizontal and vertical direction from their redundant counterpart.
