IMSR News & Events

The company states: "Terrestrial Energy and The Texas A&M University System have signed ground lease and R&D agreements. These agreements provide exclusive access and rights to approximately 77 acres at the Texas A&M-RELLIS campus in Bryan, Texas, facilitate testing activities, and cover multiple projects, including the planned commercial IMSR Plant at A&M-RELLIS. The projects were initiated following the Memorandum of Understanding (MOU) with the A&M System announced in 2025 after its selection of Terrestrial Energy to participate in its Energy Proving Ground initiative, which was established to bring advanced nuclear capacity to the campus. The initiative echoes nuclear policy objectives established by Governor Abbott and the Texas state legislature to catalyze development of advanced nuclear technologies in Texas and their rapid deployment on the ERCOT grid, one of the fastest-growing electricity markets in the country. Growing demand for reliable electricity from data centers, advanced manufacturing, industrial expansion, and other energy-intensive applications continues to drive interest in new sources of firm, carbon-free generation across Texas."

"During the quarter, Terrestrial Energy delivered against the three-pillar framework outlined in March - IMSR engineering and regulatory programs, including our key project engagements with the U.S. Department of Energy, supply chain development, and our commercial pipeline of IMSR Plant projects," said Simon Irish, CEO of Terrestrial Energy. "These developments move us closer to serving large industrial markets and the opportunity to power AI, advanced manufacturing, and the broader U.S. economy."

Terrestrial Energy announced that the U.S. Nuclear Regulatory Commission has issued its Safety Evaluation Report approving the company's Postulated Initiating Events Topical Report. This follows the NRC's acceptance of the company's final Topical Report submission announced in April 2026. The NRC's SER issuance is an approval of Terrestrial Energy's PIE methodology, which identifies and evaluates events that may challenge the safe operation of IMSR nuclear plant. This analysis is foundational to nuclear safety analysis and represents another important regulatory milestone as Terrestrial Energy systematically executes on its nuclear regulatory program. "We are pleased to report the timely issuance by the NRC of the SER on our PIE Topical Report, this follows its acceptance of final submissions just last month," said Simon Irish, CEO of Terrestrial Energy. "The scope of this Topical Report is foundational to nuclear safety analysis and future IMSR Plant licensed operation."

Terrestrial Energy (IMSR) announced that Tyler Gronbach has joined the company as Vice President of Investor Relations and Public Relations. Gronbach joins Terrestrial Energy from Wolfspeed (WOLF).
