The reactor would be placed several tens of metres underwater, several kilometres off the sea coast.
[1] The surrounding sea water would provide the heat sink for the reactor, as well as protection from attack.
Another target market for the reactor was medium-sized countries, like Monaco, which may be unsuitable for large nuclear plants.
Proponents of the Flexblue technology point out that this type of reactor would be much less prone to terrorist attacks than terrestrial-based ones.
However, nuclear reactor leaks would be much more difficult and costly to resolve underwater.
