INVESTIGATIONS INTO THE TECHNICAL AND ECONOMIC ADVANTAGES AND DISADVANTAGES OF THE "POISON CORE" FUEL ROD CONCEPT USING A ROUGH DESIGN OF A REFERENCE CORE BASED ON THE EFDR-50

Fuel rods with a central poison core contain a core of boran graphite besides the fuel in form of UO sub 2 ring tablets. The boron serves here as solid burnable neutron poison to compensate for the burn-up excess reactivity. A reactor core constructed of such fuel rods has a particularly uniform power and burn-up distribution at relatively high specific fuel power. Besides this, it exhibits safety technical advantages, in particular the boric acid use and thus the tritium production in the primary circuit can be reduced with this concept in pressurized-water reactors. The present report contains the results of the lattice studies, a rough design of a reference core, as well as fuel circuit cost estimates. (Atomindex citation 08:307163)
