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.

TEST STATUS is defined as that period following mi-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-8 ranty runs. Following this phase, the unit is generally considered by the utility to be available for commercial operation.

l 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-tication tests as specified in the purchase contract and to the accouniing policies and practices of the utility.
