NOTICE OF VIOLATION Toledo Edison Company Docket No. 50-346 Davis-Besse NPS License No. NPF-3 During an NRC inspection conducted on May 12 through June 23,1998, one violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:
10 CFR Part 50, Appendix B, Criterion lil, " Design Control," requires, in part, that measures be established to assure that applicable regulatory requirements and the design basis of structures, systems, and components are correctly translated into specifications, drawings, and instructions.
Davis-Besse Updated Saf3ty Analysis Report Section 6.2.2.6.2, states, in part, that an intake screen with a 1/4-inch screen size is installed over the emergency sump to prevent large particles from getting into the recirculating line and plugging containment spray nozzles.
Contrary to the above, as of May 22,1998, established measures were inadequate to ensure that the design basis of the containment building emergency sump (including the installation of 1/4-inch screen size over the emergency sump to prevent entry of large particles into the sump) was correctly translated into specifications, drawings, and instructions. Specifically, on May 22,1998, the inspectors identified that several 8-inch by 5/8-inch unscreened openings existed around the base of the sump screen. These openings were incorrectly specified on Drawing C-119, " Containment Vessel Interior Concrete Fill." The openings could allow particles larger than 1/4-inch to enter the sump, which, in tum, could plug containment spray nozzles that have an orifice of 13/32-inch.
This is a Severity Level IV violation (Supplement 1).
Pursuant to the provisions of 10 CFR 2.201, Toledo Edison is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region Ill, and a copy to the NRC Resident inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for each violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to av6id further violations, and (4) the date when full compliance will be achieved. Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response if an adequate reply is not received within the time specified in l
this Notice, an order or a Demand for information may be issued as to why the license should not l
be modified, suspended or revoked, or why such other action as may be proper should not be l
l taken. Where good cause is shown, consideration will be given to extending the response time.

- Notice of Violation Because your response will be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that
'it can be placed in the PDR without redaction. If personal privacy or proprietary information is necessary to provide an acceptable response, then please provide a bracketed copy of your response that identifies the information that should be protected and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of withholding (e.g., explain why the disclosure of information will create an unwarranted invasion of personal privacy or provide the information required by 10 CFR 2.790(b) to support a request for withholding confidential commercial or financial information), if safeguards information is necessary to provide an acceptable response, please provide the level of protection described in 10 CFR 73.21.
