Pikkureaktoreiden

Pikkureaktoreiden, meaning "small reactors" in Finnish, refers to a category of nuclear reactors designed to be significantly smaller in physical size and often lower in power output than traditional, large-scale nuclear power plants. These reactors are typically developed for niche applications or as alternatives to conventional energy sources. Their reduced footprint and modularity are key characteristics, enabling them to be deployed in diverse locations or for specialized purposes.

The concept of small reactors has gained traction due to several potential advantages. These include enhanced safety features, lower upfront capital costs, and greater flexibility in siting. Some designs aim for inherent safety mechanisms, reducing the reliance on active systems. Furthermore, their smaller scale can lead to shorter construction times and potentially more predictable project economics.

Applications envisioned for pikkureaktoreiden range from powering remote communities and industrial sites to providing process heat for industries like hydrogen production or desalination. They are also being explored for naval propulsion and for research purposes. Different technological approaches are being pursued, including advanced light-water reactors, high-temperature gas reactors, and molten salt reactors, each with its own set of benefits and challenges. The development and deployment of these small reactors are subject to rigorous regulatory oversight to ensure safety and security.
