Energy demand is highest in populated regions, but people do not want a reactor in their backyard.
Most people live in coastal regions, so building reactors offshore can provide energy in highly populated without the reactor being in anyones backyard.
High capital costs due to changing reactor designs and new locations for each newly build reactor. New reactor projects are over budget and delayed
Create aproduction facility near a large port, which enables the reactors to be build in one place on a production line, greatly reducing costs and eliminiating the need to move around expertise and machinery to reactor location. When using a standardised design, learnings can ensure the project remains within budget and without delays.
Decomissioning is expensive and the plant location is closed off for decades
Decommissioning can be done in a central location, which can use a standardised process, reducing costs and making it safer.
Nuclear waste is perceived as a burden on future generations.
Newer reactor designs are inherently safe and generate much less waste. Some concepts even use te waste of other reactors, thus solving its own problem.
