NOTICE OF VIOLATION GPU Nuclear Corporation Docket No. 50-289 Three Mile Island Nuclear Station License No. DPR-50 EA No.98-456 During an NRC inspection conducted between August 10 and 27,1998, a violation of NRC requirement 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 50.59 states, in part, that changes to the facility as described in the safety analysis report may be made without prior NRC approval, unless the proposed change involves a change in the technical specifications incorporated in the license or an unreviewed safety question. A change shall be deemed to involve an unreviewed safety question if a possibility for malfunction of a different type than any evaluated previously in the safety analysis report may be created.

Contrary to the above, in October 1997, a change to the facility as described in Section 6.1, Emergency Core Cooling systems, of the TMl-1 Updated Final Safety Analysis Report (UFSAR), involving an unreviewed safety question, was made without prior Commission approval. The change, which involved cross connecting the previously separate suction lines of the three high pressure injection pumps by opening valves MU-V69A and MU-V69B, created the possibility for a malfunction of '

a different type than any previously evaluated in the UFSAR in that a new potential for failure of the "C" makeup pump due to gas entrainment from the makeup tank was created.

This is a Severity Level IV violation (Supplement 1)

J Pursuant to the provisions of 10 CFR 2.201, GPU Nuclear Corporation is hereby required i to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, l ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region I, and a copy to the NRC Resident inspector at the facility that is the I subject of this Notice, within 30 days of the date of the letter transmitting this Notice of l 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 j contested, the basis for disputing the violation or severity level, (2) the corrective steps  ;

that have been taken and the results achieved, (3) the corrective steps that will be taken to  !

avoid 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 this Notice, an order or a Demand for Information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, L consideration will be given to extending the response time.

If you contest this enforcement action, you should also provide a copy of your response to i the Director, Office of Enforcement, United States Nuclear Regulatory Commission, i Washington, DC 20555-0001.
