1. OH.lECTIVE This procedure controls the overall perfonnance of the project to ; j i'

1) re-verify which field welds require radiography,

2) generate a listing of field welds,

3) re-verify radiographic package contents, and 1

4) to re-verify that NilY retains those radiographic packages for the field welds : hat requimd radiographic inspections. ,

In addition this procedun: specifies the final report outline and supporting documents, and overchecks perfonned by the NES Project Manager.

2. GENERAL Performance of the project, Verification of Radiographic Records, is conducted in accordance with three procedures. This procedure provides overall control and assembly of all infonnation developed on the project. The specific tasks to review drawings and radiographs an: perfonned under a separate procedure for each activity. Figure 2-1 provides a flow chart for the project.

63 As the data sheets from the drawing review procedure are approved by the Project Manager, the system P&ID will be highlighted to show those portions that have been completed. I 6,4 On a system basis, the Project Manager shall combine the two lists of field welds developed in 6.1 and 6.2 into a single list to show the following: '

- Field welds requiring RT where RT exists

- Field welds requiring RT where RT does not exist or there are deficiencies in the RT records  ;

- Field welds not requiring RT whem RT exists

- Field welds not requiring RT where RT does not exist 6.5 As each system is completed, the Project Manager shall submit an interim mport to the N1lY IRT Manager which will contain the following:

- The marked up P&lD developed in 6.3 above

- The list developed in 6.4 above Any discrepancies or anomalies identified for this system 6.6 After all systems have been completed, a final report will be submitted to the NilY IRT Manager, The report shall summarize the work procedure followed and the results of the review The following shall be retained by NES and referenced in the final report:

- The system reports developed in 6.5 above

- All data sheets developed during the radiograph review and drawing review plus copies of the documents used for input in the drawing review

- The signature log used in the radiograph review

- The signature log for NES employees working on this project

- Copies of Reference 1 and 2 and this procedure

- Copies of all Requests for Engineering Services, Corrective Action Requests and the NHY responses

7. OVERCIIECK In order for the Project Manager to maintain an overview of the two review tasks (6.1 and 6.2 above) he shall perform an overcheck of these tasks as follows:

7.1 On a weekly basis, the Project Manager shall select 5% of the completed data sheets from the Review of Radiographs for overcheck.

7.1.1 For each of these selected packages, he shall perform an independent review in accordance with Reference 1 and prepare a data sheet.

7.1.2 These data sheets shall be clearly marked "PM's Overcheck" across the face of the data sheet.

7.1.3 The Project Manager shall compare the results of his overcheck with the original document reviewer's data sheet. If differences occur, the Project Manager shall determine and take appropriate corrective action.

7.2 On a weekly basis, the Project Manager shall select 5% of the completed data sheets from the Review of Drawings for overcheck.

7.21 The selected ISO's or drawings shall be independently reviewed by the Project Manager in accordance with Reference 2 and data sheets prepared.

7.2.2 These overcheck data sheets shall be clearly marked "PM's Overcheck" across the face of the fomi.

7.2.3 The Project Manager shall compare the results of his overcheck with the original Field Engineer's data sheet. If differences occur, the Project Manager shall determine and take correenve action.

7.3 The Project Manager shall keep a separate file of the overcheck data sheets and any actions taken.
