Abstract
Vibrocompacted fuel should be seen not only as an unusual method, useful only for testing fuel rods containing sphere-pac fuel. In fact, the liquid metal cooled FBR BOR-60 was completely fueled with vipac fuel rods, produced in an automated pilot plant. The vipac technology was developed and studied on a laboratory scale using granulated uranium oxide with properties comparable to the original fuel. The fuel rods showed good performance and some superior aspects compared to the pellet fuel. These aspects refer to a better thermomechanical stability of the fuel, a higher degree of automation and flexibility to meet special conditions of the fuel cycle. A special condition could be the direct insertion of small amounts of granular metallic getter into the fuel rod to influence the physico-chemical properties of the fuel. A basic condition for further improvement is the use of a programmable dosing facility which we are developing and applying. The aim is to establish an automated fuel cycle technology for the minor actinide transmutation.
