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 sustamed period and completion of war-ranty runs. Following this phase. the unit is generally considered by the utility to be availab!c for commercial operation.
