Radiological evaluations and dose calculations range from simple shielding geometries for radioactive waste as well as complex geometries such as spent fuel storage and transport casks or reactor cores. The company has performed extremely complex evaluations of entire loaded arrays of nuclear fuel storage systems. Calculations cover both neutron and gamma radiation, at any distance from the source, from the cask surface to site boundaries miles away. Calculations also include occupational dose evaluations that analyze dose to personnel based on the operational steps around spent fuel casks. As an example, the figure below shows the combined neutron and gamma dose field in and around an interim storage facility with a large number of storage casks.
Finally, the Company has experience in core design for nuclear reactors, optimizing the fuel design and performing design calculations for normal and accident conditions.
