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.

Thomson scattering system for measurements of radial profile of plasma density (range 0.5-5×1021 m-3) with temperature up to 2 keV was developed at the GOL-3 facility. First harmonics (=1.06 m) of Nd glass laser is used. Scattered light from different points of plasma cross-section is imaged to a set of quartz optical fibers and detected by avalanche photodiodes.During the first 10 s after start of the relativistic electron beam injection the intense light emission from plasma is observed. Single powerful laser pulse is used for providing of good signal-noise ratio in this period. Later the plasma radiation intensity decreases and the less powerful laser oscillator operated in multiple-pulsed regime is used.Description of the diagnostics, methodical aspects of operation, and results of the density dynamics measurements are presented in the paper.
