SUMMARY

MONTH January, 1978

)

Oconee Unit I was reduced from near rated power twice during the month of January.

Power was reduced on the 7th and 8th to about 96 percent to maintain full condensate polishing flow. Power was again reduced on January 25, 1978 to about 60 percent because of feedwater pump vibra-tion. The unit was returned to near rated power following a hold to allow for xenon stability.

Information concerning personnel exposure and radioactive releases during the month will be submitted with the i

February, 1978 report.

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

~

20. UNIT AVAILABILITY FACIOR. Compute by dividing 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 (USING MDC NET). Com-pute by dividing 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 (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 dividing 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 nercent.

24. SHUTDOWNS SCHEDULED OVER NEXT 6 MONTHS (TYPE. DATE. AND DURATION OF EACHl. Include type (refueling. maintenance, 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.

25. Self-explanatory.

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

. TEST STATUS is defined as that period following 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 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 accounting policies and practices of the utility.
