SUMMARY

JULY 1993 [ UNIT 1 i i Unit 1 remains on administrative hold to resolve various TVA and NRC concerns. The operating data report reflects the assignment i of administrative hold status to unit one effective June 1, 1985. Administrative hold status is considered by TVA to suspend the accrual of reporting period hours, because this unit is considered to have a maximum dependable capacity of 0 Mwe. For this reason, cumulative reporting period hours for the period I' after June 1, 1985, to present are not considered when calculating operating status variables such as cumulative capacity factor rate. These considerations will affect the other

l operating status reporting variables accordingly.

4 r UNIT 2 l i Unit 2 operated continuously during the month of July at a capacity factor of 98.8 percent and generated 803,840 megawatt hours gross electrical power. i i ) UNIT 3 i l t Unit 3 remains on administrative hold to resolve various TVA and l NRC concerns. The operating data report reflects the assignment of administrative hold status to Unit 3 effective June 1, 1985. l Administrative hold status is considered by TVA to suspend the accrual of reporting period hours, because this unit is l considered to have a maximum dependable capacity of 0 Awe. For this reason, cumulative reporting period hours for the period after June 1, 1985, to present are not considered when ? calculating operating status variables such as cumulative I capacity factor rate. These considerations will affect the other operating status reporting variables accordingly. i i e 1 i a r- ...,--,,_n,,,-. -r-
