Dear Mr. O'Reilly:

", Duke Power Company and Westinghouse Electric Corporation have evaluated the information centained in the generic report entitled " Weld Material Documentation of the Eleven Reactor Pressure Vessels Fabricated by RDM for Westinghouse", compiled by the former Ib Rotterdamse Droogdok Maatschappij,N.V. (RDM) to satisfy the requirements presented in IE Bulletin Nos. 78-12,78-12A, and 78-12B and have concluded that the weld material data and other required information pertinent to the Catawba Unit I reactor vessel are included in RDM's report. This generic RDM report includes a certified statement by the vendor to provide further assurance that the subject report addresses all of the applicable materials used in the fabrication of the Catawba Unit I reactor vessel.

This report was submitted to the NRC on October 29, 1979, as evidenced by Westinghouse's transmittal letter, a copy of which is attached for your information.

Fsr the Catawba Unit 1 vessel, RDM has no archive material since it does not no mally maintain an inventory of excess material. Therefore, Westinghouse has inventoried archive surveillance weldment material which may be used for wri'ication purposes. This material consists of full thickness weldments made up of the following:
