QI-018 Rev. 0 1.0 PURPOSE

(

To provide methods and documentation to be used and accept / reject criteria to be applied when performing reinspection of valves.

2.0 APPLICABILITY This instruction applies to reinspection of samples selected from the population of valves which have been disassembled / reassembled at Comanche Peak, Units 1. 2 and areas common to both units.

3.0 REFERENCES

3.1 CPP-010. Preparation of Deviation Reports 3.2 CPP-011. Population Evaluation and Reports 4.0 CENERAL Asinspections are performed and documented in accordance with this instruction and established project procedures and instructions.

This instruction establishes the documentation to be used, the attributes and accept / reject criteria for reinspections of valves.

5.0 INSTRUCTION 5.1 Documentation 5.1.1 The specific valves to be reinspected are identified on

.1.

5.1.2 The ERC Issue Coordinator er designee will assenble an inspection package consisting of all the docunents pertinent to each specific valve.

Each package will coatain a checklist similar to Attachment 6.2 specific to that particular valve.

The package will also contain a package content sheet listing all drawings, travelers. Permanent Equipment Transfer's (PET's), receipt inspection information, and any other documents in the package.

(Refer to Attachment 6.3.)

5.1.3 When the package has been assembled, the Issue Coordinator will make an entry in a los similar to Attachment 6.4 and send the package to the Inspection Supervisor.

5.1.4 onreceiptofthepackage,theIntspectionSIpervisorwill ensure that it is logged on an index similar to Attachment 6.5.

He will then issue the package to a qualified inspector.

QI-018 Rev. 0 5.2 Inspection

~

l 5.2.1 The Inspector shall locate the valve and verify the valve body and bonnet markings are accessible for visual inspection (e.g.,

free of insulation).

NOTE:

If the valve markings are not visible so note on the checklist and return the package t.o the Inspection Supervisor for logging out. A new sample valve will be selected.

5.2.2 Record markings of the valve body and bonnet on the checklist.

5.2.3 Verify that the markings found are consistent with those found in the receipt inspection report (RIR). The markings will differ according to the manufacturer but in all cases must be traceable to the form NPV-1 in the RIR. Failure to be traceable is cause for rejection.

NOTE:

Valves which have PET's documenting replacement of valve bonnet's and for which the new bonnet is traceable to a form NPV-1 of a valve of identical make, pressure rating, temperature rating, metalurgical type, and code class are acceptable.

5.2.4 The inspector shall complete the checklist and route the package to the Inspection Supervisor for his review. The

(

Inspection Supervisor will log the package out and send it to the Issue Coordinator for review.

5.2.5 Should the reinspection reveal any inconsistency or abnormality the Inspector shall process a Deviation Report in accordance with Reference 3.1.

In addition to the determination of the necessity of a Safety i

l Significance Evaluation the Issue Coordinator will also indicate in block 16 of the deviation report if disassembly of l

the valve for verification of the valve internals. is to be performed.

Should the Issue Coordinator determine that proper i

valve reassembly is suspect he will so indicate this on the DR and will request that TUGC0 Mechanical Engineering have the I

valve disassembled. The Issue Coordinator will write reinspection instructions on a case basis and will coordinate with TUGC0 Mechanical Engineering to ensure necessary hold points are included in the Operational Traveler to allow for the ERC Inspector's presence at the appropriate time.

5.2.6 The overall results of the sample inspection shall be evaluated l

in accordance with Reference 3.2 l
