Abstract
STATUS OF ALLEGRO PROJECT AT VUJEPetr DAŘÍLEK, Branislav HATALA, Radoslav ZAJAC VUJE Inc., Okruzna 5, SK 918 64 Trnava, Slovakia Petr.Darilek@vuje.skABSTRACTThe goal of the ALLEGRO Project is to design, build and operate the first Gas cooled Fast Reactor (GFR) Demonstrator. The GFR belongs to the 4th generation of nuclear reactors. Prototype of the gas cooled reactor ALLEGRO is a subject of common interest of association of countries France, Slovakia, the Czech Republic and Hungary with the goal to deploy prototype of the reactor in Central Europe and present its functionality.In this article are aimed several ALLEGRO core modifications focused on criticality feasibility related to 20 % UOX fuel. Several cases for the criticality analyses are defined. These cases differ in the following parameters – number of fuel rings and fuel height.The last part of the article is proposed to technical description of the first Slovakian helium loop and experimental programme performed at this loop. 26th Symposium of AER on VVER Reactor Physics and Reactor Safety 26 10 – 14 October 2016, Helsinki, Finland
