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 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.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 signiiicant power reduction.

Report as year.month, and day.August i4.1977 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 signiticant 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.Seifwxplanatoiy.

When a shutdown extends beyond the end of a report period, count only the time to the end oi the report period and pick up the ensuing down time in the folio'wing report periods.Report duration of outages rounded to the nearest tenth of an 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.If category H must be used.supply briei'comments.

METHOD OF SHUTTINC DOWN THE REACTOR OR REDUCING POWER.Categt>rize by number designation INoie that this differs i'rom the Edison'Electric Institute (EEI)definitions of-Forced Partial Outage" and-Sche-duled Partial Outage." F>>r these tLrnis.I:Fl uses a change of..0 NIW as the break pL>int.FL>r larger pL>>ver reactors.30 MW is u>>>small a change t>>warrant cxpianatiL>>i.

in accordance with the table appearing on the report torm.If category 4 must be used, supply brief comments.LICENSEE EVENT REPORT='.Reference the applicable reportable occurrence pertaining to the outage or power reduction.

Enter 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 (NUREG416l).

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 (NUREG416I).

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.

CO>>IPONENT CODE.Select the most appropriate component from Exhibit I-Instructions for Preparation of Data Entry Sheets for Licensee Event Report (LER)File (NUREG416I).

using the following critieria:

A.If a 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 of events.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.'or events where a component designation is not applicable.

CAUSE Sc CORRECTIVE ACTION TO PREVENT"RECUR-RENCE.Use the column in a narrative fashion to ampiify or explain the circumstances of the shutdown or power reduction.

The column should include the soecific cause for each shut~down or significant power reduction and the immediate and contemplated long term corrective action taken.if appropri-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 L>r single radiation exposure speciiically associ~ated with the outage which accounts for more than 10 percent oi the allowable annual values.For long textual reports continue narrative on separate naper and reference tlie shutdown or power reduction for tins lla rfa tive.(L)/7 I cket No.: Unit Name: Completed By: Telephone:
