Gray File RE:
THREE HILE ISLAND UNIT NO.1 The Nuclear Regulatory Comnission has reviewed the infomation that you are required by your technical specifications to sue 11t as part of ~ an Annual Operating Report and has concluded that much of the infomation now included in the Annual Operating Report can be deleted and still meet the desired t!RC objectives. Therefore, we are planning to delete the requirements for an Annual Operating Report provided that certain information presently in the Annual Operating Report continues to be reported.
The purpose of this letter is to reouest that you submit a proposal to delete the requirement in your technical specifications for an Annual Operating Report. There is, however, one portion of your Annual Operating Report that must be retained in the Technical Specifications. The tabulation of occupational exposure data is needed by HRC and must continue to be subnitted on an annual basis. This tabulation may be submitted along with any report of facility changes, tests or experiments required pursuant to 10 CFR 50.59(b), or as a separate submittal if you wi sh.
In addition, we request that you concurrently modify the content of your required Monthly Operating Report. You presently nay De using three
- eport formats contained in " Reporting of Operating Infomation - Appendix A Techr.fcal Specifications" Regulatory Guide 1.16 as your monthly report.
The ' Average Daily Unit Power Level" format rmains 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 instructior.s for completing the fomats, have been revised slightly.
These revised fomats should be used starting with your monthly rrport for January 1978. Twelve copies of each of the current formats and the associated instructions are enclosed for your use. Additional copies may be obtained from our Office of Management Informatic,o and Progran Control. Along with the three recort fomats that provide much of the q

needed monthly operating information, we request that you provide a "Harrative Summary of Operating Experience" tnat describes the operation of the facility, including major safety-related maintenance, foe the monthly report period. Tne surr.;ary should be of the style and cetail sinflar to that previously prepared for inclusion into the Annual Operating Report.
This reauested "Harrative Summary of Operating Experience" is to cover each one-nonth period only and is part of the Monthly Operating Report which should be submitted by the tenth of the month following the calendar nonth covered by the report to the Director, Office of Management Infomation You should state your intentions with respect to and Progran Control.
providing this revised Monthly Operating Report when you submit a proposal to delete the Annual Operating Report.
In lieu of the 1977 Annual Operating Report, the NRC will cmpile, fron previcusly submitted reports, that information now judged necessary.
This empilation of operating data will De transmitted to each licensee for validation and addition of any missing data. Additionally, a separate, one-time only, "Harrative Surnary of Operating Experi1nce" will ce required to cover the transition perica (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 which would have contaired the narrative.
We request that you (1) propose $ change to your technical specifications that would delete the requirement for an Annual Operating Report, (2) modify the content of your montnly report, (3) provide any missing data in the summary caspilation which will be prepared and transmitted to you by NRC, and (4) provide a narrative of operating experience for the year 1977. We believe that this new reporting program will represent a significant paperwork reduction, provide core timely infomation and eliminate unnecessary infomation. We reauest that you make a submittal as soon as possible, but no later than kovceber 1,1977, so we may celete the requirerent for the suomittal of an Annual Operating Report by March 1,1978.
Sincerely, p
