Joint Institute of
Nuclear Research, Dubna. 
Research reactors (2).
About 100 kg of
plutonium.
No.
Unsafeguarded.
One reactor, the IBR-2,
is a high-flux, or pulse, reactor that uses 90 kg of plutonium dioxide fuel
(containing approximately 80 kg of plutonium metal). The reactor has an average
power of 2 MW, but its pulses can peak at 1,500 MW. The second reactor, IBR-30,
is no longer operational, but its 20 kg of plutonium metal fuel is used as a
neutron generator in a linear accelerator.
Dubna was one of six sites
recommended by Gosatomnadzor in 1995 to receive Material Protection Control and
Accountability upgrades, some of which have been installed.
