2-15-78 NARRATIVE

SUMMARY

a MONTH Januarv, 1978 Oconee Unit 2 was shut down the beginning of the month through January 16, 1978.

Work accomplished during this outage included: Replacement of two control rod drive stators, removal of 2"B" steam generator special test instrumentation, plugging 7 additional 2"B" steam generator tubes and re-plugging of 13 previously plugged 2"B" steam generator tubes.

The unit was started up and placed on line on January 16th.

Following the completion of refueling startup testing the unit achieved rated power on the 22nd.

During routine testing on January 31, the reactor tripped due to a blown fuse in the control rod drive system.

The unit was re-started and in a normal start up sequence at the end of the month.

Information concerning personnel exposure and radioactive releases during the month will be submitted with the February, 1978 report.

19. UNIT SERVICE FACTOR. Compute by dividing hours the generator was on hne (item 14) by the gross hours in the reporting period (item 11). Express as percent to the nearest tenth of a percent. Do not include reserve shut-down hours m the calculation.

UNIT AVAILABILITY FACTOR. Compute by dividmg 20 the unit available hours (item 14 plus item 15) by the gross hours in the reporting period (item 11). Express as percent to the nearest tenth of a percent.

21. UNIT CAPACITY FACTOR (USLNG MDC NET). Com-pute by disiding net electrical energy generated (item 16) by the product of maximum dependable capacity (item

7) times the gross hours in the reporting period (item i1).

Express as percent to the nearest tenth of a percent.

22. UNIT CAPACITY FACTOR (USLNG DER NET). Com-pute as in item 21. substituting design electrical rating (stem ') fu mimum dependable capacity.

23. UNIT FORCED OUTAGE RATE. Compute by dividing the total forced outage hours (from the table in Unit Shutdowns and Power Reductions) by the sum of hours generator on hne (item 14) plus total forced outage hours (from the table in Unit Shutdowns and Power Reductions).

Express as percent to the nearest tenth of a percent.

'4. SHUTDOWNS SCHEDULED OVER NEXT 6 MONTHS (TYPE, DATE. AND DURATION OF EACHl. Include type (refuehng. mamtenance, other), proposed date of start of shutdown. and proposed length of shutdown.

It is recognized that shutdowns may be scheduled between reports and that this item may not be allinclusive. Be as accurate as possible as of the date the report is prepared.

This item is to be prepared each month and updated if appropriate until the actual shutdown occurs.

2' Self-explanatory.

26. Self-explanatory. Note, however, that this information is requested for all umts in startup and power ascension test status and is not required for units already in com-mercial opera:. m.

i ST STATUS is defined as that period fellowmg 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 to be available for commercial operation.

Date of COMMERCIAL OPERATION 6 defined as the date that the unit was declared by the utility owner to j

be available for the regular production of electricity.

usually related to_ the satisfactory completion of quali.

fication tests as specified in the purthase contract and to the accounting policie= and practices of the utility.
