In total, onlytworeactors were put into operation: RBMK-1000 at the Smolensk NPP (1990) and RBMK-1500 at the Ignalina NPP (1987). The latter is fullydecommissionednow.
What is more, Lithuanian geologists have discovered that -- despite the fact that the Ignalina facility is built on a fault that was the site of an earthquake in 1907 of a magnitude of 7.1 on the Richter scale -- it is only designed to withstand tremors of up to 5.5.
