A COMPARISON OF TRANSPORT THEORY AND DIFFUSION THEORY CALCULATIONS FOR THE HIGH FLUX ISOTOPE REACTOR

Technical Report ·
OSTI ID:4240757
Comparison calculations for the High Flux Isotope Reactor (HFIR) show good agreement between multigroup diffusion-theory results and transport-theory results. Two-group diffusion theory underestimates the critical mass and the flux peaking. The calculations do substantiate the expectation of obtaining maximum unperturbed thermal fluxes of about 5 x 10/sup 15/ n/cm/sup 2/-sec in the HFIR at 100 Mw. (auth)
