ACCESSION #: 9707090271 Northeast Rope Ferry Rd. (Route 156), Nuclear Energy Waterford, CT 06385 Millstone Nuclear Power Station Northeast Nuclear Energy Company P.O. Box 128 Waterford, CT 06385-0128 (860) 447-1791 Fax (860) 444-4277 The Northeast Utilities System Docket No. 50-245 B16531 Re: 10 CFR 21.21 U.S. Nuclear Regulatory Commission JUL 3 1997 Attention: Document Control Desk Washington, DC 20555 Millstone Nuclear Power Station, Unit No. 1 10 CFR 21 Report Concerning GE Class 1E Relays Northeast Nuclear Energy Company (NNECO) is providing this letter to inform the Commission, in accordance with 10 CFR 21.21 (c)(4), that defective Class 1E electrical relays were received from General Electric Company. The non-conforming components were ordered for use at Millstone Unit No. 1. The subject relays were not installed in the plant. Initial notification of this matter was provided via facsimile notification to the NRC Operations Center in accordance with 10 CFR 21.21 (c)(3) on June 6, 1997. The information required by 10 CFR 21 is provided in Attachment 1 to this letter. There are no new commitments made in this letter. Should you have any questions, please contact R. W. Walpole at (860) 440-2191. Very truly yours, NORTHEAST NUCLEAR ENERGY COMPANY John P. McElwain Millstone Unit No. 1 Recovery Officer OS3422-5 REV. 12-95 U.S. Nuclear Regulatory Commission B16531\Page 2 Sworn to and Subscribed Before Me This Day of , 1997 Notary Public My Commission Expires Attachment: 10 CFR 21 Report Concerning Class 1E Relays Provided by General Electric Company cc: H. J. Miller, Region I Administrator Dr. W. D. Travers, Director, Special Projects Office W. D. Lanning, Director, Millstone Assessment Team S. Dembek, NRC Project Manager, Millstone Unit No. 1 T. A. Easlick, Senior Resident Inspector, Millstone Unit No. 1 Docket No. 50-245 B16531 Attachment 1 Millstone Unit No. 1 10 CFR 21 Report Concerning Class 1E Relays Provided by General Electric Company July 1997 U.S. Nuclear Regulatory Commission B16531\Attachment 1\Page 1 In accordance with 10 CFR 21.21 (c)(4), NNECO is providing the following information: (i) Name and address of the individual or individuals informing the Commission. Mr. John P. McElwain Millstone Unit No. 1 Recovery Officer Northeast Nuclear Energy Company P.O. Box 128 Waterford, Connecticut 06385-0128 (ii) Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect. GE-IFCS Class 1E Electrical Relays Millstone Nuclear Power Station, Unit No. 1 Northeast Nuclear Energy Company Waterford, Connecticut (iii) Identification of the firm constructing the facility or supplying the basic component which fails to comply or contains a defect. General Electric Company San Jose, CA (iv) Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply. The IFCS electrical relays provided by General Electric Company (GE) have been reviewed by NNECO with a focus on the dedication of the commercial product conducted under the General Electric Nuclear Energy (GENE) Quality Assurance (QA) program. The GENE commercial grade dedication program has been determined by NNECO to be inadequate in its ability to demonstrate seismic capability of these specific relays as delineated in the procurement specifications. The basic components of particular concern are GE-IFCS relays; however, the apparent weaknesses in the GE commercial-grade dedication program potentially had an impact on the qualification of the entire order of 6 other types of relays purchased under Northeast Utilities Purchase Order No. 02012938. However, NNECO has confirmed the acceptability of these other types of relays through independent testing. U.S. Nuclear Regulatory Commission B16531\Attachment 1\Page 2 The IFCS relays were received in an unusable condition and thus were not installed in the plant. However, if installed, the limiting consequence for a malfunction of the IFCS relays would be the opening of the output breaker for both the Gas-Turbine Generator and the Emergency Diesel Generator resulting in a loss of onsite Class 1E power. NNECO's inspection of the IFCS relays revealed manufacturing defects which may have impacted the structural integrity and capability of the devices. Had the damage been less severe and not identified, the relays would have been made available for installation in the plant. The installation of these relays would have most likely resulted in a situation where the relays may have proper electrical functionality unless subjected to external loads such as a Design Basis Earthquake. Thus, the relays could have appeared serviceable but would potentially not meet their design requirements. This condition, if the relays had been installed, would have represented a significant degradation of safety-related equipment and potentially a condition outside the design basis of the plant for the onsite power supplies. (v) The date on which the information of such defect or failure to comply was obtained. A Non-Conformance Report (NCR) addressing the issue was prepared on April 10, 1997. A Condition Report (CR) was then written on April 18, 1997. (vi) In the case of a basic component which contains a defect or fails to comply, the number and location of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations of this Part. The basic components of concern are GE-IFCS relays provided under Northeast Utilities Purchase Order No. 02012938. Six of the seven IFCS relays ordered were received with damage. This damage was internal and was not detected upon initial receipt inspection. However, none of the subject relays had been installed in the plant at the time of discovery. (vii) The corrective action which has been, is being, or will be taken; the name of the individual or organization responsible for the action; and the length of time that has been or will be taken to complete the action. The defective relays were returned to GENE's facility at 2015 East Bridge Boulevard, Mascot TN 37806 for repair or replacement. The subject relays were repaired by GE and returned to NNECO. The repaired relays were then inspected by NNECO and determined to be acceptable. U.S. Nuclear Regulatory Commission B16531\Attachment 1\Page 3 (viii) Any advice related to the defect or failure to comply about the facility, activity, or basic component that has been, is being, or will be given to purchasers or licensees. None. *** END OF DOCUMENT ***
