Catching Up on Studies Not Employment eutectic circuit passing through a moderator tank containing heavy water. The section of the circuit in the tank was to be made of a zirconium alloy, to minimize thermal neutron absorption. Various protective coatings insoluble in lead-bismuth eutectic were considered. The literature on bismuth and

An increase, of 10% in the coating rate constant describing the growth of ferritic coatings is caused by a decrease in the coating of 1.5% Ni, an increase of 0.09% Al, an increase of 4% Cr or a temperature increase of about 7.C. These variables act independent
