The reactor IWW-2M ( Russian исследовательский водо-водяной [реактор] , German "Research-Water-Water [-Reactor]") is a Russian research reactor operated by the Moscow Nikerdiet Institute in Saretschny in the Oblast .
investment
The research reactor is located on the site of the Nikiet Institute in the immediate vicinity of the Belojarsk nuclear power plant . Construction began on January 1, 1964, and the reactor became critical for the first time on April 23, 1966 . Extensive renovation work was carried out in 1983. The reactor is expected to remain operational until at least 2017.
The swimming pool reactor has a thermal output of 15 MW , the maximum neutron flux density for thermal neutrons is 5 × 10 14 n / (cm² * s). The reactor is operated with 90% highly enriched uranium (UO 2 ). However , there is a cooperation project with the Argonne National Laboratory to convert to low-enriched uranium. The reactor is moderated and cooled with light water and regulated with 15 control rods made of boron carbide in the reactor core .
Tests on fuel rods and reactor materials, experiments on solid state physics and studies on neutron scattering are carried out at the reactor .
Disruptions
In mid-December 2007 exceeded the observed at the site of the nuclear plant Beloyarsk radiation with 33 uR / h the allowed limit of 20 uR / h. It turned out that the cause of the increase was a shutdown of the IWW-2M research reactor due to a pressure drop in a fuel assembly . After a certain time, the measured radiation dropped again to a permissible value of 16 μR / h.
