CAREM

CAREM (Spanish: Central Argentina de Elementos Modulares) is a small modular reactor for electrical power generation under construction since 2014, near the city of Zárate, in the northern part of Buenos Aires province beside the Atucha I Nuclear Power Plant.

It is basically a simplified pressurized water reactor (PWR) designed to have an electrical output of 25MW for the first prototype, 100MW in the following one.

[1]: 20–22  The primary coolant system uses natural circulation, so there are no pumps required, which provides inherent safety against core meltdown, even in accident situations.

[2] For political reasons the project was halted but was relaunched by the 2006 Argentine nuclear reactivation plan.

[6] A new contract for finishing the concrete structures of the reactor was awarded in November 2021.
