Los reactores modulares pequeños son sistemas de energía de fisión nuclear con una capacidad de producción eléctrica generalmente inferior a 300 MWe por unidad, diseñados desde el principio para la fabricación en fábrica de módulos estandarizados, el transporte por carretera o ferrocarril hasta el emplazamiento y plazos de construcción acelerados; una inversión estructural deliberada de las centrales nucleares a medida de escala de gigavatios, cuyos sobrecostes de capital y plazos de construcción de décadas de duración paralizaron de hecho el despliegue de nuevas centrales nucleares en los mercados occidentales después de la década de 1980.
La física de los reactores y la química de los refrigerantes varían sustancialmente en toda la gama de diseños: reactores avanzados de agua ligera que extienden la tecnología probada de agua a presión a escala reducida, reactores de sales fundidas que disuelven el combustible directamente en refrigerante de fluoruro o cloruro, reactores de alta temperatura refrigerados por gas que utilizan helio y partículas de combustible TRISO, diseños de espectro rápido refrigerados por sodio y por plomo, y microrreactores térmicos destinados a emplazamientos industriales o militares remotos con una potencia inferior a 10 MWe.
Las publicaciones y patentes indexadas a continuación abordan la física de los reactores, la termohidráulica, la seguridad pasiva validación, diseño de conjunto de combustible, calificación de materiales bajo irradiación, fábrica fabricación procesos, metodología de concesión de licencias y evaluaciones tecnoeconómicas en todo este espectro de diseño.
