N2 - Transportable microreactors pose a unique shielding challenge compared with conventional reactors. Many vendors are seeking to transport a microreactor to a site, operate it for a number of months or years, and then transport it to another site. This involves providing the reactor with sufficient shielding during operations and post-irradiation transportation to ensure the safety of the public, all while making it can be transported via traditional means. This work examines the use of a nuclear-grade sandwich composite (NGSC) that seeks to combine the reactor pressure vessel and the biological shielding functions into a single unit. This work determined that the NGSC was sufficient to adequately reduce neutron and gamma current exiting the structure. The results attained show that the concept warrants further investigation as a potential combined vessel and shield option for microreactors.
