Calculations are carried out for a flux flattening experiment in the Organic Moderated Reactor critical assembly. It is proposed that the flux be flattened by varying the numbers of fuel plates per element to achieve variable fuel-tomoderator ratio. It is concluded that a reduction of the peak-to-average ratio from 1.69 to 1.17 can be achieved by this method; and that the power distribution is made more uneven by this method, so that variable fuel-to- moderator ratio is probably not desirable for full-scale power reactors.
