A Finnish group introduced building of a reactor-based heating plant that would offer residential and district heating, saying the mission would advance the district vitality mannequin and help decarbonization and electrification in Europe as extra international locations transfer away from the usage of fossil fuels for vitality.
Regular Power, an organization spun out of the VTT Technical Analysis Centre of Finland, on June 27 mentioned its heating plant can be powered by a small nuclear reactor and produce warmth at a a lot decrease temperature and stress than conventional reactors. The corporate, which introduced funding from teams together with VTT, Sure VC —a Silicon Valley investor in firms comparable to Google and Uber—and Finland’s Lifeline Ventures, mentioned the ability can be the world’s first nuclear-powered district heating plant and would make the most of VTT’s LDR-50 small modular reactor (SMR).
The corporate on Tuesday mentioned it’ll use its preliminary $2.2 million of seed funding from traders for analysis and growth of a 1:1 scale mockup that might show the performance of an SMR-powered heating plant. The mission has been a part of VTT LaunchPad, a science-based spin-off incubator. VTT LaunchPad helps groups growing VTT-owned mental property rights into fundable spin-off firms.
In Improvement Since 2020
VTT started growing the LDR-50 SMR in 2020. The corporate mentioned LDR-50 is a sort title for a reactor with a warmth output of fifty MW. The reactor is designed to function at about 150C (302F) and under 10 bar (145 psi). The group mentioned these working situations “are much less demanding in comparison with these of conventional reactors, simplifying the technical options wanted to satisfy the excessive security requirements of the nuclear trade.”
“The stress required by the LDR-50 reactor is akin to the stress that of a family espresso machine,” mentioned Tommi Nyman, CEO of Regular Power. “It operates at a decrease stress than a district heating community. This ensures that in case of a malfunction which ends up in a leak, the leak is contained inside the heating plant, with out endangering individuals or the surroundings.”
Regular Power mentioned that about half of all vitality consumed by the residential sector within the European Union (EU) goes towards heating properties. The corporate mentioned the EU’s annual district warmth consumption is about 500 TWh, with about 300 TWh of that complete produced by burning fossil fuels.
Nyman’s group mentioned there are at present about 3,500 district heating networks in Europe, serving about 60 million individuals. It mentioned decarbonizing residential heating throughout the continent represents an infinite financial alternative, and large-scale electrification of district vitality would convey a big discount in greenhouse gasoline emissions.
Nyman mentioned, “75% of district heating methods within the EU are at present powered by fossil gas. The state of affairs is even worse in China. Nuclear vitality is already a serious supply of low-carbon electrical energy, and small modular reactors symbolize a pathway to develop the usage of the expertise to different vitality sectors along with heating. On high of being safer than conventional reactors, SMRs are extra reasonably priced.
“We’re establishing an illustration plant for district heating functions ideally in Finland, however our long-term plan is to have a number of crops working world wide, producing carbon-neutral warmth to properties, places of work and for varied industrial functions,” mentioned Nyman. “We are going to convey to market the world’s greatest nuclear vitality expertise optimized for the heating sector.”
Passive Warmth Removing System
Nyman mentioned the passive warmth removing system that’s a part of the LDR-50 reactor has a serious function in its security, noting that passive methods make it doable to satisfy extraordinarily excessive security necessities with simplified expertise.
TYhe firm mentioned the LDR-50 reactor module options two nested stress vessels, with their intermediate area partly stuffed with water. It mentioned that when warmth removing by way of the first warmth exchangers is compromised, water within the intermediate area begins to boil, which types an environment friendly passive warmth switch route into the reactor pool. The system doesn’t use electrical energy, nor does it have any mechanical transferring elements, which the corporate mentioned might fail and stop the cooling operate. The group mentioned the reactor expertise was awarded a patent in 2021.

“Nuclear energy know-how, nationwide vitality coverage and the world’s main district heating community present the world’s greatest start line for Regular Power to begin its enterprise particularly in Finland,” mentioned Timo Ahopelto, founding accomplice at Lifeline Ventures.
Jyri Engeström, founder and accomplice at San Francisco, California-based Sure VC, mentioned, “Europe and america have woken as much as the truth that small reactors will turn into a part of vitality manufacturing already throughout this decade. We’re speaking a couple of very important market globally.”
Heating and Desalination
Nyman mentioned Regular Power will tailor its enterprise fashions in keeping with buyer wants. The group mentioned the 50-MW dimension of the LDR-50 can be sufficient to warmth a small metropolis, noting {that a} single plant might have a number of reactors. The corporate additionally mentioned a reactor-powered heating plant may very well be used for desalination, supporting manufacturing of contemporary water. The group mentioned its SMR-powered crops additionally may very well be modified to supply steam for industrial functions.
“At VTT, we’ve been turning hope into motion for 80 years by driving scientific innovation to alter the world and companies for the higher,” mentioned Jussi Manninen, govt vp of VTT. “Proper now, humanity is going through its most difficult adversary, local weather change. We’re on a journey to discover tomorrow’s applied sciences and innovate cutting-edge options to construct the carbon-neutral societies of the long run. Regular Power represents our dedication to our objective and embodies the hope we wish to convey to the world.”
“To protect our planet and guarantee generations to return have a wholesome planet, all combustion-based heating should come to an finish,” mentioned Nyman. “Alongside renewable vitality, nuclear vitality offers a gradual supply of vitality and warmth that meets the wants of recent society and helps us in our battle in opposition to local weather change.”
