AUG '2 91979 MEMORANDUM FOR:
G. Lainas, Chief, Plant Systems Branch, D0R THRU:
R. Ferguson, Section Leader, Plant Systems Branch, D0R -
FROM:
C. Heit, Plant Systems Branch, DOR
SUBJECT:
EVALUATION OF MONTHLY OPERATING REPORTS The licensees for operating power plants submit monthly operating reports.
At your request, I have reviewed several of these reports and evaluated "eir content for their significance to PSB, Section C responsibilities.
The purpose of this review was to determine "If there is any value in reviewing the Monthly Reports dirculated in PSB".
The requirement for submitting these reports is either Regulatory Guide 1.16 " Reporting of Operating Information - Appendix A Technical Specifications or the equivalent requirements of some plants' Technical Specifications.
In either case, monthly documents submitted usually consist of:
- 0perating Data Reports
- Average Power Level Reports
- Unit Shutdown and Power Reduction Reports
- Narrative Report - Summary of Operations
- Major Safety Related Maintenance Reports
- Refueling Reports The reports are primarily used to prepare the monthly " Gray Book" (issued by the Office of Management and Program Analysis). The " Gray Scak" is published to inform agencies and individuals interested in detecting trends in the nuclear power industry which might have safety implications or in maintainina an awareness of the U. S. Energy situation as a whole.
This book is directeu at individuals outside of the NRC.
The PMs and some PSB personnel agree these monthly operating report; are of little value to them in their work activities.
Information for their work comes from more timely reports.
Other PSB personnel contend that these reports scrve as an alert or reminder that an ernt had occurred or that they are interested in content of the Narrative ano Maintenance Reports and they like to keep a file of these reports for each assigned plant.

. The Operating Data and Average Power Level Reports contain statistical data which is of little value to the PMs or PSB personnel.
The information contained in these two reports and from the Unit Shutdown Report are recorded in the nonthly " Gray Book."
The Unit Shutdown Reports contain the LER's, forced and scheduled shutdown
~
. information.
The PMs assure me that tnis shutdown information is known well in advance of the receipt of these monthly reports.
This appears likely because these monthly reperts are at least 1/2-month to 1-1/2 months late because of the reporting rer,uirement of the Regulatory Gui.de 1.16 and of the equivalent Technical Specifications.
The guide requires that monthly reports be submitted by the 10th of the month following the calender month covered by the report.
Add to this time lag time for mailing and distribution and surely at least 1/2-month to 1-1/2 months have elapsed. Also, this report's column entitled "Cause and Cor; ::tive Actions to Prevent Recurrance" usually either omits the cause and/or the corrective actions or is rather vague about these matters.
Notable exceptions to this are the reports from D. C.-Cook, Brunswick and Browns Ferry which are detailed, whereas the other reports reviewed are vague or lack enough detail for proper review.
The Refueling Report contains boiler plate information concerning the refueling outage. These reports are of little value other than possible reference materi al.
The Narrative Reports present information on a day to day basis with or without a separate High-Light Section.
This report can provide additional information to that in the " Gray Book" regarding forced and scheduled shutdown events. Although this information is not current, it may be of some value to an individual using the " Gray Book" who wishes the detail noted in these reports.
The Major Safety Related Maintenance Report provides the reviewer / project engineer information as to problens encountered in the plant which may or may not be useful. Usually, any significant information should be known much earlier by the PMs and PSB personnel. Again, notably D C. Cook provides the most complete and meaningful run down on safety related maintenance performed.
Summary / Conclusions 1.
Tne information contained in these reports is more readily available from LERs, the PMs or other correspondence or other sources.
2.
These reports are estimated to be 1/2-month to 1-1/2 months late prior to PSB review.
3.
These monthly reports serve mainly as inp.. to the " Gray Book".
d
3-4.
The majority of operating plants should be advised to improve the content of their Narrative, Unit Shutdown anc Maintenance Reports.
In most cases, these repor,ts are either vague or incomplete.
5.
At present, I do not see the need for these reports being reviewed by Section C personnel.
