Title: Boiling water reactor fuel element - with integral nuclear superheating
Inventor: MISS ROLF-WOELTJE DIPL PHYS
IPC: G21C15/06
Filed: 1971-11-06
Abstract: The fuel element core is a closely packed structure of fissile spheres coated to inhibit fission product release and joined to form a precise geometric matrix permitting coolant flow through the interstices. Sphere diameter is extremely small and fluid flow is thereby reduced through surface adhesion. From a basic upward flow type element variants are possible including separate feed water and steam manifolds connecting to the elements, and separation of the boiling and superheating phases by means of a central tube within the fuel assembly. Coolant flow is induced to flow down through the peripheral fuel to form steam and up through the centre tube for superheating.
