Potential 10CFR50.55(e) Deficiency 55-85-05 Inadequate Design Change Control by Zack Company

-Interim Report Statement of Potentially-Reportable Deficiency / Background

.A condition potentially adverse to quality was identified in the area of design change control. This matter is based on concerns identified by Zack. Company's Corrective Action Request (CAR) No. ZCS-003. The concerns involve design change-documents for which'the review and determination for retroactivity had not been performed.

.Approximately 840 change documents were received by the Zack Company since the lifting of Stop Work Order (SWO) Nos. 14, j

15, and 20. These change documents were generic in nature and could potentially affect the adequacy of previously completed work, in that the change documents were neither-reviewed nor implemented retroactive by.the Zack Company. ,

Investigation Results ,

Illinois Power has prepared and is implementing an investigation plan to determine the extent of this deficiency at CPS. The investigation plan includes:

1. .A review committee has been designated to review all generic change documents-identified by the Zack Company since lifting.of SWO Nos. 14, 15 and 20, to determine those documents which were retroactive.

i

2. 'Sargent and Lundy.(S&L) will perform an indepen-i dent review of the documents identified by item HNo . 1.to: confirm the findings ~and submit final results to-Illinois Power (IP).

i

3. Following completion of Item 2, IP, Zack an'd S&L i  : shall jointly determine the . corrective action to

, be taken on those generic-change documents-determined to be retroactP e. [ Corrective' action may' include rework of completed items, analysis of -

nonconforming items,-or a combination of'the two.]
