Abstract
Se describe un separador de casquillo mejorado para usarse con disposiciones de barras de combustible de alta densidad dentro de paquetes de barras de combustible de reactor de agua hirviente. Los casquillos están construidos en pares de casquillos coincidentes. Cada casquillo se divide en mitades de casquillo superior e inferior. Una mitad de casquillo tienen lados del mismo con paredes removidas. La otra mitad de casquillo tienen las suyas en su lugar. Los pares de casquillo se ponen de frente con un casquillo invertido con respecto al otro y con cada pared de casquillo completa de una mitad de casquillo estando yuxtapuesta a la mitad de casquillo en la pared faltante. Preferiblemente y en la unión de tangencia entre los pares de casquillos, se define una abertura para recibir y confinar un resorte de lazo doble de tipo 'H'. La descripción incluye casquillos que tienen un contorno circular para las barras de combustible y casquillos que tienen un contorno en sección de octágono para las barras de combustible. Cada miembro del par de casquillo es simétrico y completamente intercambiable para proveer tanto un ensamble conveniente como un pequeño inventario de partes de ensamble.
