Safe and Secure

SMR-300 is an unfailingly safe and secure reactor that provides a steady source of clean energy from fission heat. The fission is used to boil water and uses steam to make power in a conventional Rankine power cycle via a turbine. This next generation reactor design incorporates passive features to ensure the unconditional safety of the reactor without any human intervention and to simplify its operation. All safety systems are located within a containment area protecting them from natural or man-made threats.

The reactor core is located deep underground, protected by a steel and concrete containment enclosure
SMR-300 is “walk-away safe,” requiring no operator actions during natural disasters, man-made threats, or for any of the conditions required to be considered by U.S. regulations
All equipment vital to the safety and security of the plant is housed deep within well-protected areas
Unlike current reactors, SMR-300’s safety systems are passive, eliminating the need for controlled equipment and other active mechanisms
A large water inventory protects the reactor core, which is designed to always remain deeply submerged SMR-300 utilizes Holtec’s HI-STORM UMAX dry storage system, safely holding spent fuel in an underground vertical ventilated module.

Economical and Efficient

SMR-300 delivers high performance with a smaller footprint. SMR-300’s innovative design requires less components, reducing the need for substantial on-site construction, and lowering operational and maintenance costs. SMR-300 has an impressive 80-year service life, two times longer than traditional nuclear power plants. The plant is designed and engineered to reduce maintenance costs and provide ease of onsite inspections. For example, the steam generator provides superheated dry steam to preserve turbine blade life. Its state-of-the-art automated data collection and diagnostic tools minimize emergent maintenance needs.
