ACCESSION #: 9703190043 microelectronics group Lucent Technologies Bell Labs Innovations Power Systems 3000 Skyline Drive Mesquite, TX 75149 March 13, 1997 Document Control Desk U.S. Nuclear Regulatory Commission Washington, DC 20555 Re: Interim Reports - Lucent Technologies, Inc. List 1S Round Cell Explosions Enclosed are Interim Reports on incidents of explosions of the Lucent Technologies' List 1S Round Cell at two (2) non-nuclear customer sites. As a follow-up to the Discovery Report, documented January 27, 1997, the preliminary investigations of the explosions indicate that improper procedures were followed. However, Lucent Technologies is conducting an extensive evaluation in order to determine whether or not a deviation or a failure to comply could create or could be associated with a substantial safety hazard. Per the analysis outlined in the Interim Reports, Lucent expects the Evaluation Report to be completed by May 19, 1997, which is one week after the final test results. The Evaluation Report will be forwarded to the Nuclear Regulatory Commission consistent with the requirements outlined in Part 21 of Title 10 of Chapter 1 of the Code of Federal Regulations. In the interim, Lucent Technologies has communicated, via PowerFlashes, a reminder to all of its customers (nuclear and non-nuclear alike) that they are to follow the safety guidelines as specified in the Round Cell Product Manual Issue 1, August 1990. If there are any questions or requests for clarification, please contact me at (972) 284-3523. Sincerely, Augustus J. Donnell Quality Director Lucent Technologies, Inc. - Dallas Works Copy to: Duke Power Pamela B. Jackson *** END OF DOCUMENT ***
