Abstract
Portal monitors are an important part of the material protection, control, and accounting (MPC&A) programs in Russia and the US. Although portal monitors are only a part of an integrated MPC&A system, they are an effective means of controlling the unauthorized movement of special nuclear material (SNM). Russian technical experts have gained experience in the use of SNM portal monitors from US experts and this has allowed them to use the monitors more effectively. Several Russian institutes and companies are designing and manufacturing SNM portal monitors in Russia. Interactions between Russian and US experts have resulted in improvements to the instruments. SNM portal monitor technology has been effectively transferred from the US to Russia and should be and permanent part of the Russian MPC&A program. Progress in the implementation of the monitors and improvements to how they are used will be discussed.
