About SMR

Small Modular Reactors

Small modular reactors (SMRs) are nuclear fission reactors that are smaller than conventional reactors. The term “small” in the context of SMRs refers to design power output.

Small modular reactors have a power output of less than 300 MWe. The term “modular” in the context of SMRs refers to its scalability and to the ability to fabricate major components of the nuclear steam supply system (NSSS) in a factory environment and then transported them to the site.

Key characteristics:


Improved safety

Easier construction

The VBER-300 is a Russian-designed small modular pressurized water reactor (PWR) that is being developed by Rosatom, the state-owned nuclear energy corporation of Russia. Here are some of the key characteristics of the VBER-300 reactor:

  1. Size and power output: The VBER-300 is designed to have a thermal capacity of 880 MW and an electrical capacity of 295 MW. It is considered a small modular reactor due to its relatively compact size and power output.
  2. Pressurized water reactor design: The VBER-300 uses a pressurized water reactor (PWR) design, which is a common type of nuclear reactor technology used in many countries around the world.
  3. Advanced safety features: The VBER-300 incorporates several advanced safety features, including a passive heat removal system, a containment vessel, and emergency core cooling systems. It is also designed to be able to shut down automatically in the event of a loss of coolant accident.
  4. Fuel technology: The VBER-300 uses low-enriched uranium fuel that is designed to operate for up to 4 years without refueling. The fuel is also designed to be highly resistant to damage and failure.
  5. Modular design: The VBER-300 is designed to be built in a modular fashion, which allows for flexible deployment and easier maintenance.
  6. International collaboration: The development of the VBER-300 reactor has involved collaboration with international partners, including China, where a joint venture was established to build a demonstration unit of the VBER-300.

The VBER-300 reactor is currently in the design phase, with plans to build a demonstration unit in Russia by 2026.

The primary purpose of this project is to help the public to learn some exciting and important information about small modular reactors.
