Micro Modular Reactor - Future of Nuclear Energy?

The Micro Modular Reactor (MMR) system is a 4th Generation nuclear energy system. MMR delivers safe, clean, and cost-effective electricity. Also, the world can use it to delivers heat to remote mines, industries, and communities. For remote location use, a Modular micro reactor is a strong competitor of diesel generator.

What is Modular Micro Reactor?

The modular micro reactor is a small size nuclear reactor as compared to regular size nuclear reactor. So, we can move the modular microreactor very easily and safely from place to place. Where a regular size reactor can supply up to 3000 MW, the MMR can supply a very small amount of MW (like 15 MW). For more energy, we can involve it in modular form.

Basic idea

1. Make a small nuclear reactor core in factory
2. Should have sealed properly and accident-proof
3. Compete for the diesel generator for use in a remote location

Component and fuel

1. Fuel: UCO and UO2 (isotope is U-235 at 10% to 20% enrichment)
2. Carbon
3. Silicon-carbide

The nuclear reaction

1. Production of fast neutrons
2. Carbon moderate (slow down) the neutrons
3. These slow neutrons do the fusion
4. If the fuel heats up both U-235 and U-238 absorb the neutrons before they get slowed and fusion stops

Helium gas is used in the cooling purpose

Safety of Micro Modular Reactor

1. It goes inside a containment concrete block
2. Stays 20 years long
3. Never opened
4. No need for refueling
5. No need for removing waste

Size of Micro Modular Reactor

Size of that can be fitted in a Truck or airplanes.

Advantages

1. It's far superior and efficient for remote area usage rather than a diesel generator
2. No pollution
3. No maintenance after construction
4. Ideal for process heat or district heating
5. For low power, the air-cooled condenser can be used

Disadvantages

1. It's expensive
2. Less knowledge
