UNITSHUTDOWNS AND POWER RE TIONS 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 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 dov:n completelyl.

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 shutdov'n 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 shouid be made for both report periods to be sure all shutdowns orsignificant 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 signiricant 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 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.

Seif<xplanatory.

When a shutdown extends beyond the end of a report period, count only the time to the end ot the report period and pick up the ensuing down time in the following report periods.

Report duratiOn of outages rounded to the nearest tenth ofanhour 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.

Categ<>rize by letter designation in accordance with the table appearing on the report t'orm. Ifcategory H must he used. supply brie i'omments.

METHOD OF SHUTTING DOWN THE REACTOR OR REDUCING POWER.

Categorize by numher designation iNoie that this dift'ers irnm the Edison Electric Institute (EEI) definitions of.-Forced Partial Outage" and

-Sche.

duled Partial Outage."

For these ter>>t~. I:El uses a cllange of

.0 MW as the break point.

For larger pov er reactors.30 MW is>><o small a change to warrant expianati<>>l.

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 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 (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 Exhibit I

~ Instructions for Preparation of Data Entry 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 reiated 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..-Thecode ZZZZZZ should be used for events where a

component, designation is not applicable.

CAUSE &, 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 ur single radiation exposure spe<<itically associ-ated with the outage which accounts for more than 10 percent oi the allowable annual values.

MAJOR SAFETY-RELATED MAINTENANCE MAY, 1980 The spent fuel pool area exhaust fan, HV-AFX-1 was delivering low flow.

Motor rotation was found to be backward.

Reversed the rotation.

A hot lead was found at the terminal block for containment lower volume vent fan, 1-HV-CLV-2B in motor control center MCC-ELC-A.

Replaced connectors on all three phases.

The sample pump for radiation monitors R-ll and R-12 would not provide sufficient flow.

The sample pump was replaced and proper operation

'verified.

Unit 1 motor driven auxiliary feedpump emergency leak-off valve closed when the pump was started.

The square root extractor and the mercoid pressure switch XPS-257 of the FFC-257 control loop required recalibra-tion.

A test was performed to verify the correct operation of the ELO valve.

The CCRP inverter failed.

Internal cables were found with cracked and missing insulation.

Arcing of the bare wires produced intermittent failure of the inverter.

The damaged cables were replaced and correct operation of the inverter was verified.
