Advances buildout of SOLO™ test infrastructure with helium leak-tight circulator for controlled experimental operations
Supports validation of reactor and closed-loop system performance under representative operating conditions
Strengthens technical foundation to de-risk development, and support commercialization
NEW YORK, April 21, 2026 (GLOBE NEWSWIRE) -- Terra Innovatum Global N.V. (NASDAQ: NKLR) (“Terra” or the “Company”), developer of the SOLO™ Micro-Modular Reactor, and Boldrocchi, a global engineering, manufacturing and service firm with more than a century of industrial experience, today announced the signing of a contract for the supply of a helium leak-tight circulator to support the experimental facilities of the SOLO™ microreactor program.
The circulator is a critical component enabling helium handling and closed-loop operation under controlled conditions, supporting validation of a key reactor and system performance while replicating real-world operating environments. Its leak-tight design is essential to maintaining system integrity and advancing the development of high-performance reactor systems.
Boldrocchi’s expertise in rotating equipment for demanding industrial applications makes it well-suited to support Terra’s experimental infrastructure where reliability and sealing integrity are essential to system validation and performance testing.
“Securing this circulator is another important step in building out the experimental infrastructure behind the SOLO™ program,” said Alessandro Petruzzi, Co-Founder and Chief Executive Officer of Terra Innovatum. “As we continue validating the systems that underpin SOLO™’s performance and deployment model, we are focused on working with experienced industrial partners that can deliver high-integrity equipment for demanding operating environments.”
“We are pleased to contribute to Terra Innovatum’s SOLO™ experimental facilities with the supply of a helium leak-tight circulator,” said Pietro Accurso, Compressor Product Director at Boldrocchi. “Helium service and closed-loop operation impose stringent requirements on sealing performance and operational reliability. This project fully leverages Boldrocchi’s engineering and manufacturing expertise.”
This milestone represents a key step in advancing SOLO™ from design validation toward deployment readiness, strengthening the technical foundation required for commercialization and scalable deployment.
