The Honorable Albert J. Gore, Jr.
President of the United States Senate Washington, D.C. 20510
Dear Mr. President:
I am forwarding the U. S. Nuclear Regulatory Commission's (NRC) " Report to Congress on Abnormal Occurrences, Fiscal Year 1997" for events at nuclear facilities. These reports are i
required by Section 208 of the Energy Reorganization Act of 1974 (PL 93-438). In the context of the Act, an abnormal occurrence (AO) is an unscheduled incident or event that the i
Commission determines to be significant from the standpoint of public health or safety. The Federal Reports Elimination and Sunset Act of 1995 (PL 104-66) requires that AOs be reported l
to Congress annually.
j The report addresses two AOs at facilities licensed or otherwise regulated by NRC. One AO involved an event at a nuclear power plant, and one involved an overexposure of a worker. The
)
report also addresses four AOs at fac!!ities licensed by the Agreement States. Agreement States are those States that have entered into a formal agreement with NRC pursuant to Section 274 of the Atomic Energy Act (AEA) to regulate certain quantities of AEA material at facilities located within their borders. Currently, there are thirty Agreement States. Regarding the Agreement State AOs, two involved overexposures of workers or a member of the public, and two involved radiopharmaceutical misadministrations. Recent information about a previously reported AO is also included in this report.
Sincerely, J

Dear Mr. Speaker:
l am forwarding the U. S. Nuclear Regulatory Commission's (NRC) " Report to Congress on Abnormal Occurrences, Fiscal Year 1997" for events at nuclear facilities. These reports are required by Section 208 of the Energy Reorganization Act of 1974 (PL 93-438).

The Federal Reports Elimination and Sunset Act of 1995 (PL 104-66) requires that AOs be reported j
to Congress annually.
The report addresses two AOs at facilities licensed or otherwise regulated by NRC. One AO involved an event at a nuclear power plant, and one involved an overexposure of a worker.' The report also addresses four AOs at facilities licensed by the Agreement States. Agreement States are those States that have entered into a formal agreement with NRC pursuant to Section 274 of the Atomic Energy Act (AEA) to regulate certain quantities of AEA material at facilities located within their borders. Currently, there are thirty Agreement States.

S:ction 208 of the Energy Reorganization Act of 1974 identf.es an abnormal occcurrence (AO) as an unscheduled incident or sv:nt that the Nuclear Regulatory Commission (NRC) determines to be significant from the standpint of public health or safety.
Th3 Federal Reports Elimination and Sunset Act of 1995 requires that AOs be reported to Congress on an anuual basis. This rtport includes those events that NRC has determined to be AOs during fiscal year 1997.
This report addresses two AOs at NRC-licensed facilities. One involved an event at a nuclear power plant, and one involved materials overexposure The report also addresses four Agreement State AOs Two of tnese AOs involved overexposures and two involved radiopharmaceutical misadminrstrations.
