At the beginning of this report period the reactor was being operated at a powcr level of 17 Init in continuatien of the test procram to demonstrate the safe and  ;

etable operation er the partial plutoniun ecre. On February let, after a core flux map j was conpleted, the pcuer level was raised to 2210!t . Operations at 22 init continued  !

until February 7th.

On February 7tn the reactor power level was increased to 23 5 lNt, licenced  !

full power. for the first tino with the partini plutonium core. Full power operation  ;

uns continuta until the norning of February 21et when a scheduled het shutdown was initiated. ,
