SUMMARY

MONTH:

March, 1978 i

Oconee 3 ran at near rated power almost the complete month. On 3/18, a small reduction was made to perform periodic tests and returned to near rated power. On 3/30, power was reduced to 75% to remove the i

i 3B1 RCP from service because of a low oil load alarm on the upper oil pot.

The unit remained at this load the remainder of the month.

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

20. UNil AVAILABILITY FACTOR. 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 disiding net electrical energy generated (item 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 ratmg

(' 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 ime (item 14) plus total forced outage hours (from the table in Unit Shutdowns and Pow er Reductions).

Express as percent to the nearest tenth of a percent.

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

It is recognized that shutduwns may be scheduled i. atween reports and that this item may not be allinclusive. 2-n accurate as possible as of the date the report is prepared.

2 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 staius and is not required for units already in con -

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 su tained 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.
