l OPERATIONAL

SUMMARY

l APRIL 1993 l

I I

t UNIT 1 Unit i remains on administrative hold to resolve various TVA and NRC concerns.

The operating data report reflects the assignment of administrative hold status to unit one effective June 1, 1985.

1 Administrative hold status is considered by TVA to suspend the.

l accrual of reporting period hours, because this unit is i

considered to have a maximum dependable capacity of 0 Mwe.

For this reason, cumulative reporting period hours for the period after June 1, 1985, to present are not considered when l

calculating operating status variables such as cumulative l

capacity factor rate.

These considerations will affect the other 1

operating status reporting variables accordingly.

)

t 4

~

UNIT 2 Unit 2 entered a refueling outage on January 29, 1993.- The

~

estimated unit restart is May 21, 1993 (Startup Mode).

The reporting factors have been rev'. sed to reflect the administrative hold status for Unit 2 from June 1, 1985 until restart for l

cycle 6 (May 24, 1991).

l I

'I UNIT 3 J

i Unit 3 remains on administrative hold to resolve various TVA and NRC concerns.

The operating data report reflects-the assignment

.l 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

~

considered to have a maximum ~ dependable capacity of 0 Mwe.

For

_i this reason, cumulative reporting period hours for the period i

after June 1, 1985, to present are not considered when l

calculating operating status variables such as cumulative

(

capacity factor rate.

These considerations will affect the other j

operating status reporting variables-accordingly.
