SUMMARY

MONTH January, 1978 Oconee Unit 3 was reduced from near rated power from the 4th to the 8th to allow turbine generator moisture separator reheater drains to be directed to the main condenser and again on January 14th when reactor coolant pump 3B1 was removed from service due to a low oil level. The unit was shut down from January 21st to January 26th to repair a body to bonnet leak on core flood valve 3CFl and add oil to reactor coolant pump 3B1 motor bearing reservoir.

Following a normal start up, the unit operated at near rated power the remainder of the month.

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

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

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

21. UNIT CAPACITY FACTOR (USING MDC NET). Com-pute by disiding net electrical energy generated (stem 18) by the product of maximum dependable capacity (item

7) times the gross hours in the reporting period (item 11).

Express as percent to the nearest tenth of a percent

22. UNIT CAPACITY FACTOR (USING DER NET). Com-pute as in item 21. substituting design electrical rating (item 5) for maximum dependable capacity.

23. UNIT FORCED OUTAGE RATE. Compute by dividmg the total forced outage hours (from the table in Unit Shutdowns and Power Reductions) by the sum of hours generator on line (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.

24. SHUTDOWNS SCHEDULED OVER NEXT 6 MONTHS (TYPE. DATE. AND DURATION OF EACH). 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 pessible as of the date the report is prepared.

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

25. Self-explanatory.

26. Self explanatory. Note. however. that this information i

is requested for all units in startup and power ascension test status and is not required for units already in com-rnercial operation.

TEST STATUS is defmed as that period following ini-tial critieahty during which the unit is tested at succes-sively higher outputs. culminating with operation at full power for a sustamed period and completion of w -

ranty runs. Following this phase. the unit is generally considered by the utility to be available for commercial operation.

Date of COMMERCIAL OPERATION is defined as the

-date that the ' unit was declared by the utility owner to be available for the regular production of electricity.

usually -related to the satisfactory completion of quali.

fication tests as specified in the purchase contract and to the secounting policies and practices of the utility.
