UilITSHUTDOWNS AND POWER REDU LIONS INSTRUCTIONS This report should describe all plant shutdowns during the report period.

In addition. it should be the source of explan-ation of significant dips in average power levels.

Each signi-ficant reduction in power level (greater than 2¹ reduction in average daily power level for the preceding 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ) should be noted, even though the unit may not have been shut down completely 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 Recurrenc:

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 signirtcant reduction in power for that calendar year.

Shen 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.

Auaust 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 significant power reducuons are reported.

TYPE.. Use "F" or "S" to indicate either "Forced" or "Sche.

duled," respectively, for each shutdown or significant power reducrion.

Forced shutdowns inciude 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 of a report period, count only the time to the end oi the report period and pic'p the ensuing down time in the following report periods.

Report duration ofoutages rounded to the nearest tenth ofan hour to faciiitate 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 vn the report form. Ifcategory H must be used. supply brief comments.

METHOD OF SHUTTING DOWN THE REACTOR OR REDUCING POWER.

Categorize by number designation iNoie thar this differs t'rom the Edison Electric Institute IEEI) definitions oi'Forced Partial Outage" and

-Sche.

duled Partial Outage."

For these terni~. I:Fl uses a cliange oi'0

~IW as the break point.

For larger power reactors. i0 MW is iii'ismall a change to warrant explanatiain.

in accordance with the table appearing on the report form.

Ifcategory 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 Preparauon of Data Entry Sheets for Licensee Event Report (LER) File (NUREC4161).

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.) Ifthe outage or power reduction will not result in a reportable occurrence.

the positive indication of this lack ot corr Iation should be noted as not applicable Qt/A).

SYSTE!Vi CODE.

The system in which the outage or power reducuon originated should be noted by the two digit code oi Exhibit G

~ Instructions for Preparation of Data Entry Sheets for Licensee Event Report (LER) File (NUREG4161).

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 Exhibii I - Instructions for Preparation of Data Entq Sheets for Licensee Event Report (LER) File {NUREG4161).

using the followingcritieria:

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 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 for events where a

component designation is not applicable.

CAUSE & CORRECTIVE ACTION TO PREYED RECUR-RFRCE.

Use the column in a narrauve fashion to amplify or explain the circumstanc s 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 vr 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 cominue narrative on separate paper ani reference the shutdown or power reduction i'oi tiu>
