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.

Tokamak equilibria with a snowflake divertor configuration are studied using a wire current model in toroidal geometry. A set of conditions for the formation of a snowflake divertor that can also be applied in full equilibrium calculations using a Grad-Shafranov solver is presented. It is shown that by taking into account the vertical force balance of the plasma, previously obtained results using a simple wire model have to be corrected. For a reactor-type device with coils far away from the plasma to accommodate the shielding requirements, the poloidal field coil currents become so high that they will represent a major technological challenge.
