The present paper addresses eight possible routes of producing 99Mo, and discusses both yield and 99Mo specific activities (SA) in the context of future anticipated worldwide demand. The dimensions of the targets are modelled by considering both the limits set by cooling and those by inside-target radiation attenuation characteristics. Energy deposition profiles are modelled by MCNP6, the reaction probabilities are taken from TALYS/TENDL and JANIS codes, and both are used in calculating produced 99Mo. The results suggest that U neutron-fission may remain one of the most relevant and efficient means of producing 99Mo, but that new developments may surface, such as ADSR or AHR production modes. Accelerator- based 99Mo production is discussed as asking for developments in both the cooling of targets and new concepts in post-EOB upgrading of 99Mo SA, and/or new concepts for 99Mo/99mTc-generators, the latter possibly in both volumes (mass) and 99Mo capacities.
