-J Gentlemen:

RE: DAVIS BESSE UNIT T20.1 The Nuclear Regulatory Connission has reviewed the infor:ation t".at you are requireo by your technical specifications to submit as cart of an Annual Operating Report and has concludea that mucn of the infornation now included in the Annual Operatino Repcrt can be celeted anc still scet the desired.WC objectives. Therefore, we are planning to delete the requirecents for an Annual Operating P.cport provided that certain infomation presently in the Annual Cparating Reg -t conti.iues to De reported.

The purpose of this letter is to request that you submit a preposal to delete the requireHent in your technical specifications for an Annual Operating Report. There is, how=ver, one portion of your Annual Operating Report that must be retained in the Technical Specifications. The tabulation of occupational exposure data is needed by fRC and '::Ust continue to be sunaitted on an annual basis. This tabulation cay be submitted along with any report of facility changes, tests or experinents requiree. pursuant to 10 CFR 50.59(b), or as a separate subaittal if you wi sh.

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

The " Average Daily Unit Power Level" femat renahs the same and should continue to be used. The other two femats, "Oper'a'ing Da ta Report" and " Unit Shutdowns and Power Reductions", along with their associated instructions for completing the formats, have been revised slightly.

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

associated instructions are enclosed for yoor use. Additional copies UF

s Tol.edo Edison Company SEP 2 21977 needed nonthly operating infomation, we request that you provide a

" Narrative Suemarv nf Operating Experience" that describes the operatinn of the facility,

,luding major safety-related maintenance, for the monthly recort period. The sumary should be of the style and detail sioilar to that previously orepared for inclusion into the Annual Operating Report.

This requested

• Narrative Sur,:aary of Operating Experience" is to cover each one-month period only and is part of the 11onthly Operating Report which should De submitted by the tenth of the month following the calendar month covered by the report to the Of rector, Of fice of 11anagement Infomation and Program Control. You should state your intentions with respect to providing this revised Monthly Operating Report when you suomit a proposal to de~lete the Annual Operating Report.

In lieu of the 1977 Annual Operating Report, the NRC will ccmpile, from previously sutoitted reports, that information now judged necessary.

This conpflation of operating data will be transmitted to each licensee for validation and aadition of any missing data. Additionally, a separate, one-tise only, " Narrative Sumary of Operating Experience" will be required to cover the transition period (calendar year 1977) t$ecause the narrative of ocerating experience was not submitted wi th previous Monthly Operating Reoorts nor will there be an Annual Operating Report which would have contained the narrative.

We request that you (1) propose a change to your technical specifications that would delete the requirement for an Annual Operating Resort, (2) modify the content of your monthly recort, (3) provide any missing data in the sumnary co1pilation which will be prepared and transatttec to you by HRC, 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 eliminata unnecessary infomation. We request that you nake a submittal as soon as possinle, but no later tnan Noveriber 1,1977, so we may delete the requirsaent for the submittal of an Annual Operating Report by liarch 1,1973.

TEST STATUS is defined as that period following ini-ttal enticality dunng which the unit is tested at succes.

j sively higher outputs, culmmating with operation at full power for a sustamed penod and completion of war-ranty runs. Fol!owtng this phase, the unit is generaily considered by the utility to be available for commeretal operation.

Date of COMMERCIAL OPERATION is detined as the date that the unit was declared by the utility owner to be available for the regular production of electncity, usually related to the satisfactory completion of quali-rication tests as specified in the purchase centract 2nd to the accountmg polic:es and pr2ettees of the utility.
