A Jimmy generator supplies heat at a highly competitive price compared with other heat sources, offering guaranteed price predictability over 20 to 30 years and enabling industrial customers to shield themselves from energy market volatility.

A Jimmy generator produces heat at 470°C without emitting CO₂, avoiding nearly 100,000 tonnes of CO₂ equivalent emissions per year.

As third-generation reactors, SMRs feature inherent and passive safety characteristics that enable natural cooling of the reactor core.The use of TRISO fuel ensures that fission products remain contained at temperatures of up to 1,600°C, a threshold that is never reached thanks to the natural cooling of the reactor core.Les SMR étant des générateurs dits de 3^ème génération, ils disposent de propriétés physiques assurant une sureté intrinsèque et passive qui permettent un refroidissement naturel du cœur

L’utilisation de combustible dit « TRISO » confine les produits de fission jusqu’à 1600°C, température qui n’est jamais atteinte grâce au refroidissement naturel du cœur

Jimmy has chosen a High-Temperature Reactor (HTR) design, a well-documented technology dating back to the 1970s that has been used for decades, with reactors operating in several countries, including Japan and China.

A Jimmy generator is installed, operated and decommissioned by Jimmy. Depending on the industrial site's requirements and energy consumption, one or more generators can be combined to deliver the appropriate thermal output.
