Reynolds, A B

The assembly will be a mocknp of the Mixed Spectrum Superheater Reactor, an integral superheater reactor in which boiling occurs in an annular thermal section and steam is superheated in an unmoderated fast section in the center. The assembly is described, and the results of physics design calculations are presented. Power distributions, criticality parameters, loadings, reactivity distributions, control system and core worths, reactivity due to Doppler effect and axial fuel expansion in the fast section, effects of flooding the fast section, and thermal-core Doppler and void coefficients were calculated. Three methods under consideration for the measurement of the Doppler effect in the fast core are also discussed. (D.C.W.)
