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

20. UNIT AVAILABILITY FACTOR. Compute by dividing the unit available hours (item 14 plus item 15) by the gross hours in the reporting period (item i1). 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 18) by the product of maximum dependable capacity (item

Express as percent to the ne,mt tenth of a percent.

24. SHUTDOWNS SCHEDULED OVER NEXT 6 MONTHS (TYPE, DATE. AND DURATION OF EACH). 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 r3 ports 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.

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 denned 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 specined in the purchase contract and to the accounting policies and practices of the utihty.
