Radiogenic Lead with Dominant Content of 208Pb: New Coolant and Neutron Moderator for Innovative Nuclear Facilities

Science and Technology of Nuclear Installations, 2011
As a rule materials of small atomic weight (light and heavy water, graphite, and so on) are used as neutron moderators and reflectors. A new very heavy atomic weight moderator is proposed—radiogenic lead consisting mainly of isotope 208Pb.

Computational investigation of 99Mo, 89Sr, and 131I production rates in a subcritical UO2(NO3)2 aqueous solution reactor driven by a 30-MeV proton accelerator

Nuclear Engineering and Technology, 2015
The use of subcritical aqueous homogenous reactors driven by accelerators presents an attractive alternative for producing 99Mo. In this method, the medical isotope production system itself is used to extract 99Mo or other radioisotopes so that there is ...
