SAFETY ANALYSES i ATLAS test data taken at pressures from 14.7 psia to 800 psia indicate that the fuel assembly critical power at this flow is approximately 3.35 MWt. With ;
the design peaking factors, this corresponds to a
- THERMAL POWER > 55 RTP. Thus a THERMAL POWER limit
- of 2 5 RTP for reactor pressure < 785 psig is conservative. Because of the design therwal hydraulic cc=ptibility of the reload fuel designs with the cycle 1 fuel, this justification and the associated low pressure and low flow limits remain applicable for r
