Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Total mass attenuation coefficients of aqueous solutions of urea, having concentrations ranging from 0.06 to 0.22 g/cm3, have been determined by performing transmission experiments in a narrow beam geometry at 662 keV. The sphere transmission method has also been employed for the direct measurement of mass energy absorption coefficients of these solutions by placing a point source of 137Cs inside a spherical shell. Analysis of the experimental data in terms of cross sections and effective atomic numbers is presented.
