Gentiemen:

f RE: YANKEE-ROWE ATOMIC POWER STATION l 5

The Nuclear Regulatory Commission has reviewed the. infomation that you  !

are required by your tec;-ical specifications to submit as part of an l Annual Operating Report ;ad has concluded that much of the infomation  !

now included in the An.ual Operating Report can be deleted and still meet i the desired NRC objectives. Therefore, we are planning to delete the l requirements for an Annual Operating Report provided that certain l infomation presently in the Annual Operating Report continues to '

be reported.

i The purpose of this letter is to request that you submit a proposal to ,

delete the ' requirement in your technical specifications for an Annual l Operating Report. There is, however, one portion of your Annual Operating  ;

Report that must be retained in the Technical Specifications. The i tabulation of occupational exposure data is needed by NRC and must continue to be submitted on an annual basis. This tabulation may be j submitted along with any report of facility changes, tests or experiments I required pursuant to 10 CFR 50.59(b), or as a separate submittal if you wish. -

In addition, we request that you concurrently modify the content of your required Monthly Operating Report. You presently may be using three report fomats contained in " Reporting of Operating Information - Appendix A Technical Specifications" Regulatory Guide 1.16 as your monthly report.

The " Average Daily Unit Power Level" fomat remains the same and should continue to be used. The other two fomats, " Operating Data Report" and " Unit Shutdowns and Power Reductions", along with their associated instructions for completing the fomats, have been revised slightly.

These revised fomats should be used starting with your monthly report for January 1978. Twelve copies of each of the current fomats and the )

associated instructions are enclosed for your use. Additional copies may be obtained from our Office of Management Infomation and Program Control . Along with the three report fomats that provide much of the i

[ Yankee Atomic Electric Company SEP 161977 needed monthly operating infomation, we request that you provide a

" Narrative Summary of Operating Experience" that describes the operation of the facility, including major safety-related maintenance, for. the monthly report period. The summary should be of the -style and detail similar to that previously prepared for inclusion 'into the Annual Operating Report. l This requested " Narrative Summary of Operating Experience" is to cover 'l

. each one-month period only and is part of the Monthly Operating Report' l which should be submitted by the tenth of the month.following the calendar month covered by the report to the Director, Office of Management Infomation and Program Control. You should state your intentions with respect to providing this revised Monthly Operating Report when you submit a proposal l to delote 'the Annual Operating Report. J In lieu of the 1977 Annual Operating Report, the NRC will compile, from previously submitted reports, that infomation now judged necessary.

This compilation of operating data will be transmitted to each licensee i for validation and addition of any missing data. Additionally, a separate, l one-time only, " Narrative Summary of Operating Experience" will be required to cover the transition period (calendar year 1977) because ,

the narrative of operating experience was not submitted with previous Monthly Operating Reports nor will there be an Annual Operating Report I which would have contained the narrative.  !

We request that you (1) propose.a change to your technical specifications j that would delete the requirement for an Annual Operating Rep'rt, (2) 1 modify the content of your monthly report, (3) provide any missing data 1 in the summary compilation which will be prepared and transmitted to you  !

by NRC, and (4) provide a narrative of operating experience for the year l 1977. We believe that this new reporting program will represent a significant i paperwork reduction, provide more timely infomation and eliminate unnecessary I infomation. We request that you make a submittal as soon as possible, but no later than November 1,1977, so we may delete the requirement for the f submittal of an Annual Operating Report by March 1,1978. '
