TECHNOLOGICAL DIFFERENCES FROM OLDER NUCLEAR PLANTS

 USNC’s MMR technology is considerably different from the traditional nuclear plants of the past for a number of reasons.

Simply put, conventional nuclear plants split uranium atoms to release a significant amount of heat. This heat boils water, turning it into steam that rises and spins turbines to generate energy. Cooling towers are used to cool the steam to convert it back into water, which is then reused.

Used fuel contains radioactive material, which is extremely hazardous to human health, and can leak out of its containment areas if some type of damage occurs to the nuclear plant. One example is the Fukushima Daiichi Accident (2011), which happened when an earthquake-triggered tsunami crashed into the nuclear plant and caused three nuclear meltdowns that leaked radioactive materials for several days.

Darlington said that SMRs are often referred to as “fourth generation advanced nuclear technology” that was designed to never release any radioactive materials into the environment.

The SMR’s reactor vessel, which is transportable and the size of a tanker truck, comes pre-fuelled and acts as a “nuclear battery.” The fuel inside of this vessel are solid kernels made from a mix of uranium, carbon, and oxygen, with each being roughly the size of a poppy seed. These kernels, which are covered in several ceramic coatings, are then encased in a diamond-like substance, which USNC calls Fully Ceramic Micro-Encapsulated (FCM) Fuel.
