First deployment site for the SOLO™ micro-modular reactor announced

It is Rock City Admiral Parkway Development, a six-million square-foot industrial park in Valmeyer, IL near St. Louis.

GSR III Acquisition Corp., a publicly traded special purpose acquisition company, and Terra Innovatum Srl, a developer of micro-modular nuclear reactors, have announced that the latter entity signed a Memorandum of Understanding with Rock City Admiral Parkway Development, a six-million square-foot industrial park in Valmeyer, IL, to host the first deployment site for the SOLO™ micro-modular reactor.

According to the announcement, this strategic agreement grants Terra Innovatum dedicated use of Rock City’s land for the licensing, testing, and construction of the company’s first-of-a-kind SOLO™ reactor. Subject to customary approvals, Terra Innovatum will supply Rock City’s industrial, logistics, food distribution, and government clients with clean and reliable power from the SOLO™ reactor with an option to subsequently deploy 50 reactors on site, delivering up to 50 MWe for commercial use.

“We are thrilled to partner with Rock City on the siting of our first SOLO™ reactor, which sets the critical foundation needed for the development and anticipated commercial operation of our innovative nuclear solution,” said Alessandro Petruzzi, Co-Founder and Chief Executive Officer of Terra Innovatum. “Rock City is the perfect location for our first deployment as it showcases the massive real-world application potential of our micro-modular reactors and is in close proximity to a hotbed of nuclear research and talent. SOLO™’s modular design enables it to easily integrate into Rock City’s existing infrastructure, providing clean and reliable energy production at the point of demand without the need to connect to the grid.”
