UitIT SHUTDOWNS AiIDPOWER RE

. IONS 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 sieni ~

ficant reduction in power level (ereater than 20% reduction in averaee 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 completelyi.

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.

IVhen 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 sieniticant power reduction.

Report as year. month. and day.

Aueust 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-rnent 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 rapport 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 duratibn of outages rounded to the nearest tenth ofan hour to faciTitate 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 on the report t'orm. Ifcategory H must be used. supply briei'comments.

METHOD OF SHUTTING DOWN THE REACTOR OR REDUCING POWER.

Categorize by number desienation INoie that this dift'ers i'om the Edison Electric Institute IEEI) definitions of -Forced Partial Outaee" and

-Sche.

duled Partial Outage."

Fiir these tcrnii. I;Fl uses u change oi'0 MW as the break p<<int.

For larger power reactors. 30 MW is iiio small u <<hunee to warrant explanation.

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 (NUREG416I).

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 (NIA).

SYSTFM CODE.

The system in which the outage or power reduction originated should be noted by the two digit <<ode 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 following critieria:

A. Ifa component failed,use the component directlyinvolved.

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 mai ~

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 wnere a

component designation is,not.applicable.

CAUSE"8: CORRECTIVE ACTION TO, PREVENT RECUR-RENCE.

Use the column in.a narrative fashion to ampiify 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 outaee or power reduction includine an identification of the critical path activity and a report of any sinele release of radioactivity or single radiation exposure speciiically associ-ated with the outaee which accounts for more thun 10 percent oi the allowable annual values.

For long textual reports continue narrative on separate paper anil reterence the shutdown or power reduction for ibis narrative.

JUNE, 1980 M-2 C&I-1 CKI-2 Engineered safety feature ventilation fan 2-HV-AES-1 breaker tripped on thermal overload.

Motor leads and end of power supply cable were found burned up.

Replaced motor and had ventilation unit tested.

Engineered safety feature ventilation fan HV-AES-2 motor power leads burned up at the junction box.

The motor was replaced and new power cable installed.

The unit tested satisfactorily following replacement.

A ground condition was indicated on the AB battery when a steam dump signal was applied to the steam dump valve.

The problem was caused by worn insulation at solenoid valve URV-132.

The worn insulation was replaced to eliminate the ground fault.

No.

4 accumulator hi-low level alarm was in, with the level indicators showing normal level.

Investigation disclosed that the low alarm ILA-140 was out of calibration.

The Unit was recalibrated and the level alarm cleared.
