'2Cuifeb States Senate WASHINGTON. D.C. 20510 Post Office Box 1938 Portland, Maine 04104 October 4, 1982 Carlton Kammerer Director, Office of Congressional Affairs Nuclear Regulatory Commission 1717 H Street, N.W.
Washington, D.C.

Dear Mr. Kammerer:
Senator Cohen has recently been contacted by Maria Holt of Bath, Maine, who works with the Mid-Coast Health Research Group.
This organization is interested in monitoring the License Event Reports prepared for events that occur at the Maine Yankee nuclear power plant in Wiscasset.
According to Ms. Holt, the format for the License Event Reports has recently been modified.
In June, the NRC began supplying the Wiscasset library with a monthly book of license event reports as well as the forms previously used.
Since August, the library has only received the book.
As you can see by the attached example, the. book format does not include the detailed statistical information contained on the previously used forms.
As a health researcher, Ms. Holt needs the additional information.
I would greatly appreciate your reviewing this matter and advising me why the format change was made and what actions could be taken which would allow Ms. Holt to have access to more detailed information.
Thank you very much for your time and efforts on behalf of Senator Cohen.
Sincerely,
/
C&L Rebecca L. Amsden Staff Assistant to Senator Bill Cohen RLA/rmb Enclosure A:

PRELIMINARY LABORATORY ANALYSIS INDICATES POSSIBLE STRESS CORROSION FAILURE.
ADDITIONAL LABORATORY ANALYSIS IS BEING PERFORMED TO DETERMINE ACTUAL MODE OF FAILURE.
PRIOR TO RESTART ALL MANWAY STUDS FROM REMAINING S/G'S HAVE TO BE MAGNETIC PARTICLE AND ULTRASONICALLY TESTED TO VERIFY THAT THE STUD FAILURES ARE LIMITED TO THE 62 S/G TC MANWAY.

LOSS OF PRESSURIZER LEVEL WAS DUE TO MALPOSITIONING OF AN RHR ISOLATION VALVE AND AN RHR RECIRCULATION VAIVE.
THE ISOLATION VALVt SHOULD HAVE LEEN CLOSED PRIOR TO l
OPLMING THE RECIRCULATION VALVE. PRESSURIZER LEVEL WAS NORMALIEED USING CHARGING PUMPS TAKING SUCTION FROM RWST.
OPERATIONS DEPARTMENT WILL IESUE A MEMO TO ALL OPERATORS RE-EMPHASIZING THE IMPORTANCE OF ADHERENCE TO PLANT PROCEDURES.

OCT 20 092 The Honorable William S. Cohen United States Senate Was' Ngton, DC 20510
Dear Senator Cohen:
This is in response to Ms. Rebecca L. Amsden's letter of October 4,1982, regarding concerns expressed by Ms. Maria Holt of Bath, Maine, whose organi-zation, the Mid-Coast Health Research Group, is interested in monitoring the Licensee Event Reports (LERs) prepared for events that occur at the Maine Yankee Atomic Power Station in Wiscasset, Maine. Ms. Holt indicated that she needed access to the detailed information contained in the LERs, a
and thought that because of a recent modification in the format of a monthly sumary of LERs, this information was no longer available at the Wiscasset Public Library, the Nuclear Regulatory Commission's (NRC's) l-Local Public Document Room (LPDR) for Maine Yankee.
There has been i change in the format and procedures for licensees reporting individual LERs, and this infomation continues to be made available for inspection and copying at the Wiscasset Public Library. The only recent change involved the refomatting of the monthly summary of LERs, not the LER submittal or distribution.
In this regard, seven new LERs or followup reports to previously identified LERs concerning Maine Yankee have been received since August 1982, and we have confimed that these reports are on file at the Library.
Copies are enclosed for your infomation.
Also enclosed are copies of NRC Regulatory Guide 1.16. " Reporting of Operating Information--Appendix A, Technical Specifications, and NUREG-0161, Instructions for Preparation of Data Entry Sheets for Licensee Event Report (LER) File, Revision 1," which describe in detail 'the current procedures for LER reporting.
l For your infomation, the NRC has under consideration revisions to the LER l
reporting procedure.
On May 6,1982, a proposed rule was published in the l
Federal Register entitled, Licensee Event Report System" (copy enclosed).
The proposed rule would revise and codify the existing. LER system; however, licensees would still be required to submit detailed reports on significant operating events. The NRC is now reviewing the responses received on the proposed rule during the public coment period which ended in July 1982.
