Title: Vented nuclear fuel element
Inventor: GAUTHRON MAURICE
IPC: G21C3/17
Filed: 1968-07-12
Abstract: 1,205,283. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 12 July, 1968 [13 July, 1967], No. 33480/68. Heading G6C. A fuel element for a liquid metal cooled reactor is provided with a vent for the discharge of fission product gases, comprising a tube 2 integral with the lower end portion of the fuel can 12, a first plug 4 of porous material placed within the tube 2, a compartment 3 closed at the upper end by the plug 4 and separated from the liquid metal coolant at the lower end by a second plug 6 and, inside the compartment 3, a powdered material 5 entrained in liquid metal which has passed through the plug 6. The pore size of the material forming the plug 4 is such that the plug is impermeable to the liquid metal since the powdered material 5 with which this is loaded has a sufficient grain size and/or increases the surface tension of the liquid metal. The plug 6 is formed of two layers 6a, 6b of material having pore size decreasing from the compartment 3 to the exterior of the tube 2 with the pores of the outer material being of larger size than those of the material of the plug 4. The powdered material 5 can consist either of impurities which are usually transported by the liquid metal coolant such as, for example, sodium monoxide when the reactor is cooled by liquid sodium, or of a powder having a particle size of 0À01 to 1Á, for example, an alkali metal oxide, an alkaline earth metal oxide, silica or alumina. Inside the compartment 3, the plug 6 is covered by a packing 7 of stainless steel wool which on displacement of the liquid metal from the compartment 3 holds up the powdered material 5 while at the same time it permits the free passage of the fission product gases through the plug 6. Initially, the plug 4 is blocked by the powdered material 5 but when the pressure of the fission product gases exceeds that of the liquid metal coolant, the liquid metal is forced out of the compartment 3 and the gases are vented through the plug 6. The decreasing dimensions of the pores of the layers 6a, 6b produce a filtering action on both the displaced liquid metal and the fission product gases. The vent may alternatively be at the top of the fuel can. In another embodiment (Fig. 4), a discharge pipe 28 is disposed parallel to a tube 20 within an extension 25 of the fuel can 12, a porous plug 24 closing the tube 20 and a porous plug 30 the pipe 28. The plug 30 together with a plug 26 closes the bottom of the can extension 25. The powdered material is dispersed within the compartment 23 but not within the pipe 28 so that the fission product gases can escape through the pipe 28 when the powder contacts the plug 26.
