NUCLEAR SUPERHEAT DEVELOPMENT PROGRAM ELEVENTH QUARTERLY PROGRESS REPORT, JANUARY-MARCH 1962

OSTI ID:4827838

Completion of the final reference design of NUSU using double-annular fuel elements is reported. Data from previously outlined critical experiments with annular multitude elements are presented along with data on azimuthal powem peaking in fuel elements adjacent to large water gaps. Results of an investigation concerning the dependence of control effectiveness of flux-trap type reds on size, moderator content, and poison concentration are included. The NUSU fuel element (outer annulus of the double-annular fuel element), was satisfactorily operated for about two months and is being thermally cycled to confirm suspected leaks. Preliminary tests with both Hastelloy-X and Inconel as alternate superheat cladding materials appear satisfactory on visual and photographic examination. Additional examination with microphotographs is necessary. (J.R.D.)
