1. Nature of defect or failure to comply:

l The as built drawings for the Reactor Pressure Vessel (RPV) are incorrect which is )

a deviation in the requirement of the reactor pressure vessel procurement document.

2. Date Identified: April 24, 1982 i

3. Basic component information (if applicable):

a. Supplier: Combustion Engineering j

)

i b. Component Quantity: On e t

c. Where Located: Reactor Pressure Vessel

't

4. Na ture of the defect or failure to comply and the safety hazard which was or could be created:

During construction of the RPV the intermediate shell was rotated 15' with respect to the lower shell. This resulted in the intermediate shell longitudinal welds being located in a different position than specified on the RPV drawings. This error in the as built drawings could result in failure to inspect the longitudinal welds during the inservice inspection of the RPV which could allow flaws (if any were to exist) in the welds to go undetected.

5. Advice related to the defect or failure to comply received from supplier:

The vendor recommended that the drawings be updated. Since this defect only ef fects the ISI program which the vendor is not a part of, no other recom-mendation was made.

6. Corrective action that was, is, will be taken; and length of time that has been or will be taken to complete the action: (Attach additional sheets as necessary.)

The Reactor Pressure Vessel will be inspected using-the proper locations for tia intermediate shell longitudinal welds. This inspection will be completed during the 1982 refueling outage.
