f

( 2.1.2 The results obtained using these sample plans vill be evaluated in accordance with Reference 6.7.

2.2 Definitions 2.2.1 Lot: Collection of items from which a sample is drawn.

For the Overinspection program, the lot may be developed from travellcrs in a Turnover Package, items in a spec-ified ari a or system, groups of like items such as large bore pipe hangers, or small bore pipe, conduit, etc.

2.2.2 Master Lot Number: A number assigned by IP Overinspection to a let.made up of one or more Balduin Associates' (BA) lot (s) to assure traceability betueen IP and BA lots.

2.2.3 Monconformance

Deficiency in characteristic which renders the quality of an item unacceptable or indetermi-nate.

2.2.4 Overinspection

Program to provide additional inspection of previously verified items.

2.2.5 Random

Obj ective process in uhich all items being considered have an equal chance of selection. In the N100-184 (12-79) Page 1 5 of

ILLINOIS POWER COMPANY QAI- 710.08 QUALITY ASSURANCE INSTRUCTION Revision

{

overinspection program, randomness vill be achieved by the use of randon numbers.

2.2.6 Sample Plan: The required sample size for a given lot (Appendix 7.1).

2.2.7 Traveler

Document listing vork activities to be per-formed, their sequence, scope, requirements, etc.

2.2.8 Turnover Package: Appropriate documentation provided for a systeu, sub-system, area, etc. designated for turnover as a unit.

3.0 RESPONSIBILITIES 3.1 The Supervisor - Helding, NDE and Testing is responsible for the implementation of the Overinspection Program.

3.2 The Area Overinspection Supervisor (AOIS) reports to the Supervisor - Welding, NDE and Testing and is responsible tor:

( a. training of personnel implementing this QAI

b. verification of Overinspection Sample Plans 3.3 The Discipline Overinspection Supervisor (DOIS) reports to the AOIS and is responsible for:

a. preparation of Overinspection Sample Plans

b. determining the applicable Checklist (s)

c. assignment of inspection personnel

d. revicu and approval of completed inspection reports and checklists.

4.0 IMSTRUCTIONS 4.1 Baldwin Associates (BA) shall transmit a report of the results of their field verification inspections of each lot ,

submitted to Illinois Power Supervisor-Uelding, NDE and l Testing for Overinspection. The report shall define the following:

Traveler numbers Component numbers Inaccessible items UCRs initiated.

4.2 The Supervisor - Welding, NDE and Testing shall then foruard the Field Verification Report to the AOIS for action by the appropriate DOIS, who will initiate the Overinspection Sample Plan Form, Appendix 7.2. The DOIS shall obtain a Master Lot number from the Overinspection QA Analyst in accordance with Reference 6.3.

HOTE 1 Identification of lots and the population of the lot may be provided by BA prior to completion of BA inspections in order to allow IP to determine sample size and develop inspection packages.

r

\. NOTE 2 Lots submitted by BA that are comprised of items in the same discipline (electrical, HVAC, etc.) may be combined as approved by the Supervisor - Helding, NDE and Testing.

4.3 The DOIS shall determine which drawing (s) (design / supplier detailed drauings) are required, initiate and transmit a Request for Documents, Form JV-319(BA), to the BA Document Control Center for the required drawing (s).

All drawings utilized in the Overinspection prccess shall be marked with the Overinspection Report number and Master Lot number.
