50 YEARS AFTER THE START-UP OF BR-2 - THE FIRST FAST REACTOR IN EUROPE

摘要

February 14, 2006 is the 50th anniversary of the start-up of the first fast reactor in Europe - the BR-2. This was an important step in the development of fast reactors for nucler power production. Experience in operating a core under conditions with cramped bundles of fuel elements and a liquid-metal coolant with heat flows through the surface of the claddings of about 1.2·10~6 kJ/(m~2 ·h) was gained for the first time on the BR-2 reactor. Investigations performed on the BR-2 of the breeding ratio showed that BR = 1.8 ± 0.3. The first experience of physical start-up of a fast reactor, determining the efficiency of the reactivity control organs and their calibration, was gained.
