Aiming particularly at the market for direct energy supply to industrial customers, the new reactor designers are breaking away from the historical model by developing reactors that are 10 to 400 times less powerful than the EPR reactor in Flamanville, hence their designation as ‘small’ reactors.
The thermal power of the SMRs currently monitored by the ASNR is between 10 and 540 MWth.
This significant reduction in power also implies a radical adaptation of the economic model for the development of these reactors, on the one hand by seeking to reduce construction times, and on the other hand by relying on standardization and mass production.
It is this new industrial model of mass production with a large proportion of factory prefabrication that gives these reactors the name ‘modular’ small reactors.
