d. Al'Etijled Block Trio Siillnr.

The Al'R!l rod block trip setting shall be:

Sgg<; 0. 66 V 4 42% - .66 LN where:

S gg ~ llod block sett ing in percent of rated tllerlDnl poWor (2381 11Wt)

W and AW nre defined in Specification 2.1.A.1.n.

In the event of operation wit h a maximum f ract ion of limiting power density (!!Fl.PD) greater thnu the fraction of rated power (FRP), the setting shalI be moditled as follows:

S ggs (0.66 W 1 42% - 0.66 AW) _JJ L lirl.I'D where, FRP - Irnet ion of t at ed thermal power (2381 ItWL) 11Fl.PD - maximum f t act 1on of 1imit lug power densi t y where the 1imiting power density f or each type of fuel hundle is speelfled in t he Core Operat ing 1.imit s llepo r t.

The intlo of FRP t o itFl.PD shall be set equni to 1.0 unless the act uni operat ing value is less than the design value of 1.0, in which en:;e the actuni operntlug value will be used.
