Winters, C E; Secoy, C.H. eds.

The HRE process flow diagram is given, as are diagrams of the tank assembly, the recombiner assembly, and the air flow system. Calculations and preliminary design work are also discussed. Data are given on control and simulator design for the HRE. A detailed evaluation was made of the thermal neutron absorption in the reactor. Data are also given induced activity in stainless steel, steel, and barytes concrete. Self shielding dath are given for various reactor components. The dynamics of the HRE were analyzed, and data are given in graphical form. The simulator was used to obtain data on the effect of a step function in reactivity. The general equations of motion of the reactor are given. Corrosion studies include stueles of protective treatments for stainless steels, corrosion resistance of stainless steels, Zr, and reflector materials, and corrosion in uranyl sulfate systems. Radiation stability and in- pile corrosion tests are described. Results of the tests are briefly summarized. pictorial results of the work done on induction methods of soldering and of pretreated and corrosion-tested stainless steel are included. Studies of the recombination of H and O are summarized. Pilot tests of recombiners are discussed. Data are included on the solubility of fission product sulfates at high temperatures and pressures. Methods for the analytical chemical control of the homogeneous reactor solution are discussed. A study of the properties of the thorium nitrate-water system was completed. Data are given on the behavior of uranium slurries. Methods of the continuous removal of fission products from horaogeneous reactor solutions are discussed. (D.E.B.)
