Rosatom’s SMR NPP projects are based on the state-of-the-art RITM series reactors, whose design incorporated many years of experience in operating small reactors in the icebreaker fleet.

SMR NPPs with RITM-200 reactors have a number of advantages:

• increased safety;
• modular design and layout depending on the customer’s needs;
• scalability;
• factory-made units reduce the scope and costs of construction and installation.

RITM-series reactors can be used for various purposes including propelling ships and icebreakers and generating power at on-land and off-shore nuclear plants.

RITM-series reactors

Maneuverability

RITM-200 SMR NPPs can control reactor power output to generate electricity to meet the load requirements in the grid (30-100% of rated power). Power output can be varied by up to 1% per second of the maximum design capacity, which makes it possible to quickly reach and adjust the required load parameters.

Safety

Rosatom’s small nuclear power plants ensure safety and resistance to external impacts. This is a result of utilizing active and passive systems developed to account for the post-Fukushima safety requirements and consistently implement the defense-in-depth protection of the reactor vessel.

Long operating period without refueling

The plant’s unique fuel allows for continuous operation without refueling for up to 6 years (for SMR NPPs) and for up to 10 years (for optimized floating power units). This comes in compliance with all Russian and international rules and regulations including non-proliferation.

Ease of transportation

The main components of on-land SMR NPPs can be easily transported:

• by rail using a special platform car;
• by road using heavy duty vehicles;
• by water transport.

The rest of the equipment has a modular design, which allows for its transportation using regular means of transport.

The floating power unit is fully manufactured at the shipbuilding facility using mature technologies of nuclear icebreaker production. The floating design minimizes the scope and costs of capital construction on site of the nuclear plant. Once fuel is loaded and comprehensive tests are performed, the floating unit is towed to its place of operation where the plant is connected to the grid on shore and begins energy generation.
