Westfall, R M; Knight, J R

The two-dimensional DOT-IV discrete-ordinates program was applied in analyses of the K-33 cell floor radiation levels due to four hypothetical criticality events. The radiation sources correspond to leakage spectra from critical uranyl fluoride solutions ranging from 1.2 to 4.95 weight percent enrichment. For the criticality-alarm-system ANSI Standard 8.3 minimum accident of concern (1200 Rad/hour at 2 meters from the surface of the critical volume), the dose rates at the maximum source-detector distance vary from approximately 150 to 200 mRad/hour of either neutron or photon radiation. The report includes a discussion of the methodology employed in the study, biological dose rates, thermal neutron reaction rates and appended dose rate plots. 10 references, 15 figures, 7 tables.
