8. If changes occur in capacity ratings (items number 3 through 7) since last report, give reasons: 3 l

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.
