RE:
WINE <fILE POINT NUCLEAR STATION UNIT NO.
1 The Nuclear Regulatory Commission has reviewed the=information that you are required by your technical specifications to,submit as part of an
, 'nnual 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 HRC objectives.
Therefore, we are planning to delete the requirements for an Annual Oper'ating Report provided that certain information presently in the Annual Operating Report continues to be reported.
The purpose of this letter is to request that you submit a proposal to delete'he requirement in your technical specifications f'r 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 coptinue to be submitted 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 ifyou wish.
In addition, we request that you concurrently modify the content of your required Honthly Operating Report.
You presently may be using three report formats contained in "Reporting of Operating Infomation - Appendix A Technical Specifications" Regulatory Guide 1.16 as your monthly report.
The "Average Daily Unit Power Level" format remains the same and should continue to be used.
The other two formats, "Operating Data Report" and "Unit Shutdowns and Power Reductions",
along with their associated instructions for completing the fomats, have been revised slightly.-
These revised formats should be used starting with your monthly report
'or January 1970.
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 tianagement Information and Program
- Control, Along with the three report formats that provide much of the OFFICE~

4 Niagara tiohaHk Po>ger Corporation scps s ~y7 needed monthly operating information, we request that you provide a "Narrative Summary'f 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.
This requested "Narrative Summary of Operating Experience" is to cover each one-month period only and is part of the fhnthly Operating Report which should be submitted by the tenth of the month following the calendar month covered by the repor t to the Director, Office of Management Information and Program Control.
You should state your intentions with respect to providing this revised Honthly Operating Repor t when you submit a proposal to delete the Annual Operating Report.
In lieu of the 1977 Annual Operating Report, the NRC will compile, from previously submitted reports, that information now judged necessary.
This compilation of operating data will be transmitted to each licensee for validation and addition of any missing data.
Additionally, a separate, 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 Honthly Operating Reports nor will there be an Annual Operating Report
~Ihich would have contained the narrative.
'Ile request that you (1) propose a change to your technical specifications that would delete the requirement for an Annual Operating Report, (2) modify the content of your monthly repor t, (3) provide any missing data in the summary compilation which >All be prepared and transmitted to you by NRC, and {4) provide a narrative of operating experience for the year 1977.
He believe that this new reporting program will represent a significant paperwork reduction, provide more timely information and eliminate unnecessary information.
He 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 liarch 1, 1978.

UNITSHUTDOWNS AND POWER REDUCTIONS INSTRUCTIONS This report should describe,all plant shutdowns during the report period.
In addition, it should be the source ofexplan-ation of significant dips in average power levels, Each signi-ficant "reduction in power level (greater than 20% reduction in average daily power level for the preceding 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) should be noted, even though the unit may not have been shut 'down completely1.
For such reductions in power level, the duration should be listed as zero, the method of reduction should be listed as 4 (Other), and the Cause and Corrective Action to Prevent Recurrence column should explain.
The Cause and Corrective Action to Prevent Recurrence column should be used to provide any needed explanation to fully describe the circumstances of the outage or power reduction.
NUMBER.
This column should indicate the sequential num-ber assigned to each shutdown or significant reduction in power for that calendar year.
When a shutdown or significant power reduction begins in one rcport period and ends in another, an entry should be made for both report periods to be sure all shutdowns or significant power reductions are reported.
Until a unit has achieved its first power generation, no num-ber should be assigned to each entry.
DATE.
This column should indicate the date of the start of each shutdown or significant power reduction.
Report as year, month, and day.
August 14. 1977 would be reported as 770814.
When a shutdown or significant power reduction begins in one report period and ends in another, an entry should be made for both report periods to be sure all shutdowns or significant power reductions are reported.
TYPE.
Use "F" or "S" to indicate either "Forced" or "Sche.
duled," respectively, for each shutdown or significant power reduction.
Forced shutdowns include those required to be initiated by no later than the weekend following discovery of an off-normal condition.
It is recognized that some judg-ment is required in categorizing shutdowns in this way.
In
- general, a forced shutdown is one that would not have been completed in the absence of the condition for which corrective action was taken.
DURATION.
Selfwxplanatory.
When a shutdown extends beyond the end ot'a report period, count only the time to the end of'the report period and pick up the ensuing down time in the following report periods.
Report duration of outages
~
rounded to the nearest tenth ofan hour to facilitate summation.
The sum of the total outage hours plus the hours the genera.
tor was on line should equal the gross hours in the reporting period.
REASON.
Categorize by letter designation in accordance with the table appearing un the report t'orm. Ifcategory H must he used. supply briei comments.
METHOD OF SHUTTING DOWN THE REACTOR OR REDUCING POWER.
Categorize by number designation INuie that this dift'ers I'ruin the Edison Electric Institute
{EEI) definitions of -Forced Partial Outage-and "Sche.
duled Partial Outage."
Fur these term~. EEI uses a change ut'0 MW as the break point.
Fur larger power reactors.30MW Is li>u sIIIJII a change tII warrant explanaliull.
in accordance with the table appearing on the report form Ifcategory 4 must be used, supply brief comments.
LICENSEE EVENT REPORT g.
Reference the applicable reportable occurrence pertaining to the outage or power reduction.'nter the first four parts (event year, sequential report number, occurrence code and report type) of the five part designation as described in Item 17 of Instructions for Preparation of Data Entry Sheets for Licensee Event Report (LER) File (NUREG4161).
This information may not be immediately evident for all such shutdowns, of course, since further investigation may be required to ascertain whether or not 'a reportable occurrence was involved.) If the outage or power reduction will not result in a reportable occurrence.
the positive indication of this lack of correlation should be noted as not applicable (N/A).
SYSTEM CODE.
The system in which the outage or power reduction originated should be noted by the two digit code of Exhibit G
~ Instructions for Preparation of Data Entry Sheets for Licensee Event Report (LER) File (NUREG-0161).
Systems that do not fit any existing code should be designa-ted XX. The code ZZ should be used for those events where a system is not applicable.
COMPONENT CODE. Select the most appropriate component from Exhibit I - In<tructions for Preparation of Data Entry Sheets for Licensee Event Report (LER) File (NUREG4161).
using the following critieria:
A. Ifa component failed, use the component directly involved.
B. If not a component failure, use the related component:
e.g..
wrong valve operated through error: list valve as component.
C. If a chain of failures occurs, the first component to mal.
function should be listed. The sequence ofevents, includ-ing the other components which fail, should be described under the Cause and Corrective Action to Prevent Recur.
rence column.
Components that do not fit any existing code should be de.
signated XXXXXX. The code ZZZZZZ should be used for events where a
component designation is not applicable.
CAUSE Sc CORRECTIVE ACTION TO PREVENT RECUR-RENCE.
Use the column in a narrative fashion to amplify or explain the circumstances of the shutdown or power reduction.
The column should include the specific cause for each shut.
down or significant power reduction and the immediate and contemplated long term corrective action taken, ifappropri-ate.
This column should also be used for a description of the major safety. related corrective maintenance performed during the outage or power reduction including an identification of the critical path activity and a report of any single release of radioactivity or single radiation exposure specitically associ
~
ated with the outage which accounts for more than 10 percent of the allowable annual values.

This item is to be prepared each month and updated if appropriate until the actual shutdown occurs.
- 25. Selfwxplanatory.
- 26. Selfwxplanatory.
Note, however, that this information is requested for all units in startup and power ascension test status and is not required for units already in com-mercial, operation.
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'o be available for commercial operation.
Date oi'OMMERCIALOPERATION 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-fication tests as specified in the purchase contract and to the accounting policies and practices of the utility.
