g RE:

RAcio SECO fiUCLEAR GENERATIhG STATION o

The Nuclear Regulatory Connission has reviewed the information that you are required by your technical specifications to sub5.it as part of an Annual Operating Report ane has concluded that r:cch of tha infomation now included in the Annual Operating Report can be deleted and still neet the desired IMC objectives. Therefore, we are planning to celete tne reouirements for an Annual Operating Report provided that certain infomation presently in the Annual Operating Peport continues to be reported.

The purpose of this letter is to request that you rubait a proposal to delete the requircrent in your technical specifications for an Annual Ocerating Reoort. There is, houever, one portion of your Annual Operating Report that nust be retained in the Technical Specifications. The tabulation of occupational exposure data is needed oy !7<C and cust continue to be submitted en an annual Dasis. This tabulation Ny oc submitted along with any report of facility changes, tests or experittents required pursuant to 10 CFR 50.59(b), or as a separate sunnittal if you t,i sh.

In addition, we request that you concurrently podify the content of your required I onthly Operatino neport.

You presently nay be usino three report fomats contained in "Reportino of Operating Intomation - f.ppcodix A Technical Specifications" Requlatory Guide 1.16 as your nonthly report.

The " Average Daily Unit Forer Level" femat remains the same and should

.i-continue to be used. The other two fomats, "Cierating Data Report" h

and " Unit Shutdowns and Power Reductions", along with their associatc0 instructions for crepleting the formats, have oeen revised slightly.

These revised fomats should be usca starting with your r.cothly report for January 1976.

Twelve copies of each of the currant fer.uts and the N

}

associated instructions are enclosed for your usc. Accitional copies ray be ct:tained fron our Of fice of IMnagerent Infomation and Progra'...

f needed monthly operating infomation, we request that you provide a "flarrative Su: nary of Operating Experience" that describes the operation of the facility, including major safety-related maintenance, for the i,onthly

report period. The surmary should be of the style and detail similar to L.==

j that previously prepared for inclusion into the Annual Operating Report.

i:

This requested "Itarrative Sunnary of Operating Experience" is to cover each one-month period only and is part of the lionthly 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 tianagement Infomation i..;

and Program Control.

You sheuld state your intentions with respect to

[:

providing this revised ltonthly Operating Report when you sux11t a proposal p

to delete the Annual Operating Report.

e.= = =

In licu of the 1977 Annual Operating Report, the NRC will ccr: pile, fron

[4 ~

previously subnitted reports, that infomation now judged necessary.

This compilation of operating data will be transmitted to each licensee for validation and addition of any nissing data. Additionally, a separate, one-time only, "t!arrative Sumary of Operating Experience" will be n 25 required to cover the transition period (calenaar year 1977) because

=

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

[

i Me request that you (1) propose a change to your technical specifications L

that would delete the requirement for an Annual Operating Report, (2)

[

nodify the content of your nonthly report. (3) provide any missing data in the sumnary compilation which will be prepared and transnitted to you by IRC, and (4) provide a narrative of operating experience for the year 1977. Me believe that this new.eporting program will represent a significant paperwork reduction, provide nore tinely infomation and eliminate unnecessary infomation. We request that you nake a submittal as soon as possible, but J

no later than November 1,1977, so ve may delete the requirement for the subaittal of an Annual Operating Report by liarch 1,1978.
