's September 22. 1977 Docket Nos. 50-245 and 50-336 Northeast Nuclear Energy Company ATTN: Mr. Donald C. Switzer President P. O. Box 270 Hartford, Connecticut 06101 4
Gentlemen:
RE: MILLST0t!E NUCLEAR POWER STATION Ut11TS NOS.1 AND 2 The Nuclear Regulatory Commission has reviewed the infomation that you i
are required by your technical specifications to submit as part of an Annual Operating Report and has concluied that much of the infomation now included in the Annual Operatind; Report can be celeted and still meet the desired HRC objectives. Therefore, we are planning to delete the requirements for an Annual Operating Report provided that certain infomation presently in the Annual Operating Report continues to dg be reported.
The purpose of this letter is to request 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 NRC and must continue to be suomitted 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
{
wish.
l In addition, we request that you concurrently modify the content of your I
I required Monthly Operatina Report.
You presently may be using three-report fornats contained in " Reporting of Operating Infomation - Appenaix l
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 femats, " Operating Data 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 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 Manaqcment Infomation and Program Control. Along with the three report fomats that provide much of the O

needed monthly operating information, we request that you provide a
" Narrative Summary of Operating Experience" that oescribes the operation j
of the facility, including major safety-related maintenance, for the monthly report period. The summary should be of the style and detail similar to i
that previously prepared for inclusion into the Annual Operating Report.
This requested "Harrative Summary of Operating Experience" is to cover each one-month period only and is part of the Monthly Operating Report 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 to delete the Annual Operating Report.
In lieu of the 1977 Annual Operating Report, the NRC will campile, from previously submitted reports, that infomation now judged necessary.
This compilation of operating oata will be transmitted to each licensee for validation ano addition of any missing data. Additionally, a separate, i
one-time only, "Harrative 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 i
Monthly Operating Reports nor will there be an Annual Operating Report j
which would have contained the narrative.
- ^)
We request that you (1) propose a change to your technical specifications V
that would delete the requirement for an Annual Operating Report, (2) modify the content of your monthly report, (3) provide any missing data 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 1977. We believe that this new reporting program will represent a significant paperwork reduction, provide more timely infomation and eliminate unnecessary 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
, submittal of an Annual Operating Report by March 1,1978.
Sincerely, George L r, Chief Operating Reactors Branch r3 Division of Operating Reactors

TEST STATUS is defined as that period following ini.
(
tial criticality during which the unit is tested at succes-sively higher outputs, culminating with operation at full power for a sustained period and completion of war-
. ranty runs. Following this phase, the unit is generally considered by the utility to be available for commercial operation.
Date of COMMERCIAL OPERATION is defined as the
-]
date that the unit was declared by the utility owner to be available for the regular production of electricity, usually related to the satisfactory. completion of quali-3 fication tests as specified in the purchase contract and to
' the accounting policies and practices of the utility.
