Shielding Evaluations – Methodology

MCNP5 Monte Carlo, release 1.41 Computed exterior dose rate (mrem/hr) for 1 Ci of each

energy line or nuclide distributed in the cavity Tallied on segmented (10 cm high segments) cask surface, 2

meters from the vehicle surface and at the cab surface Determined the maximum value on the cask surface, 2

meter surface and cab surface; this defined the dose rate response functions in mrem/hr/curie

Computed responses for the side, top and bottom Utilized ANSI/ANS 6.1.1-1977, Neutron and Gamma Flux-To-

Dose Conversion Factors

Shielding Evaluations

Max. Ci/g addresses non homogeneity . Analysis assumes max. Ci/g is homogenously

distributed throughout the cavity. Resins generally saturate and are uniform in

activity Nylon filter media takes no credit for metal

cartridge and material is filled through the cavity. End user is ultimately responsible for determining

the maximum Curie per gram of their contents.

Shielding Evaluations Sensitivity Study Results

Compaction results in lower side and top dose rates, but a slight increase (2%) in the bottom

0.65 g/cm3 produces the lowest Max. Ci/g Carbon produced the lowest gamma attenuation. NCT and

HAC polystyrene gamma responses are increased by 1.07, 1.10 and 1.09 for the side, bottom and top, respectively.

Zeolite has the lowest neutron attenuation. NCT and HAC polystyrene neutron responses are increased by 3.10, 2.75 and 5.40 for the side, bottom and top, respectively.

Beta/Bremsstrahlung: NCT and HAC responses are negligible. NCT < 1E-6 mrem/hr/Ci and HAC < 1E-4 mrem/hr/Ci.

Neutron NCT and HAC responses evaluated and incorporated into results. However, activities are typically low, and the contributions are negligible.
