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 Fenerator 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 NFXT 6 MONTHS (TYPE. DATE. AND DURATION OF EACH). Include type (refuelinF. 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<xplanatory.
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 ptrAer for a sustained period and completion of war-ranty runs. Following this phase the unit is generally considered by the utihty 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-lication tests as specified in the purchase contract and to the accounting pohcies and practices of the utility.
