The equivalent scenario for research reactors like ours, known as a BORAX accident, does not produce an ... dispersal in the cooling water of a large amount of molten aluminium in the form of very fine droplets then caused the water to vaporise ...

1967 and that the high-flux reactor went critical for the first time in 1971. However, the lifetime of a reactor is linked to the aging of the components “bombarded” by the neutrons (the flux), in particular ... installation then restarted in 1995, the first and only time this operation has ever been performed on a reactor. This vessel has ...

This is a particularly unfavourable assumption, as the water in the pool is an extremely efficient filter for retaining a very large proportion of the radioactive fission ... The most serious accident would be a core meltdown following the loss of the water inventory. It is on the basis of this extremely ...

also lead to a slight increase in the pressure inside the containment. In the worst possible situation, i.e. on a very hot summer day, the pressure in the containment would rise within a few hours to stabilise ... the event of a core meltdown, the reactor containment is immediately isolated. In the hours following the accident, the pressure inside ...

In a nutshell ... positive charges (referred to as divalent or multivalent ions). This process requires a highly selective membrane. A material which is ...
