Revise Item 2 - Nuclear Core of Section B - DESIGN FIATURES to read in its entirety:
2.
Jiuclear Core F.nvimum core diameter (circumscribed circle) 129 in.
Maximum active fuel length, cold 112 in.
2 Marimum number of fuel assemblies by types:
Type III 36 Type III-F 52 I
Type V 82 I
Type VI 78 Type VII (equivalent to Type VI) 85 r
Type VII-Pu 11 Type VIII (equivalent to Type VI) 120 Type IX (equivalent to Type VI) 50 Maximum total number of fuel assemblies 483 The reactor may be operated at any power up to and including rated power with any configuration of the varicus types of fuel assemblics loaded essentially in a 1 in 4 scatter of fuel, provided the maxicum nuraber of assemblias is within the limits specified above.

Revise Ite:: 3 - Determination of Maximum Reactor Powar of Section D
POWER OPERATION to read in its entirety:
3.
Determination of Mav4 mum Reactor Power he rated power of the reactor shall be limited to a t:axic:um steady state value of 700 E(t).
The==vimna# steady state heat flux shall never c::cced 360,000 hTU/ (hr)(f t ).
The reactor shall be operated within the above limit such that a =4ai=2m critical heat flux ratic of at least 1.5, evaluated at 125% of rated power, will be maintained in the fuel closest to burnout based on uniform steam quality over the cross sectinn of each channel. This critical heat flux ratio shall be based upon the correlation in Edison's "Reconsnended Curves of Burnout Limit for Design and Operation of Boiling Water Reactors", dated s
January 5, 1962.* The reactor shall be operated always well within the bounds of stability, as evidenced by the operation itself and any experimental data produced.
