OPEllATING DATA REPORT (ADDITIONAL PAGE) l Ooeratina Status I-l 8.

If changes occur in capacity ratings (items number 3 through 7) since last report, l

give reasons:

3 i

i The Nameplate Rating (Gross MWe), item Number.4, has been changed l

from 1138 MWe to 1092 MWe.1138 MWe represents the gross output with j

the Turbine Control Valves Wide Open (VWO). Umerick's Unit 1 licensed ~

i maximum reactor power will not produce enough steam to operate at VWO, therefore the nameplate rating has been adjusted to 1092 MWe.1092 MWe

{

represents the output derived from the turbine manufacture's heat balance j

st the licensed maximum reactor power. The Limerick Unit 2 Nameplate l

Rating has already been established at its maximum reactor power rating j

following the Power UpRate last month.
