Story summary

Steady Energy has begun constructing a 50-megawatt pilot plant in Helsinki to develop Europe's first small nuclear heat reactor, with a budget of 20 million euros.
The facility will provide energy for district heating rather than traditional power generation.
Tommi Nyman, CEO of Steady Energy, states the project focuses on low-heat generation, which is easier to manage.
Steady Energy has partnered with the Helsinki energy group Helen, which is investing in a new nuclear unit after Finland closed its last coal plant.
The final reactor is expected to cost around 100 million euros.
