Summary. The Gas Turbine – Modular Helium Reactor (GT-MHR) couples a High Temperature Gas-cooled Reactor (HTGR) with a Brayton power conversion cycle to produce electricity at high efficiency. It is based on HTGR technology developed over the past. 40 years that includes the design, construction and operation of seven HTGR plants.

The Gas Turbine – Modular Helium Reactor: A Promising Option for Near Term Deployment. The Gas Turbine – Modular Helium Reactor (GT-MHR) is an advanced nuclear power system that offers unparalleled safety, high thermal efficiency, environmental advantages, and competitive electricity….

Abstract. The Gas Turbine-Modular Helium Reactor (GT-MHR) is the result of coupling the evolution of a low power density passively safe modular reactor with key technology developments in the U.S. during the last decade: large industrial gas turbines; large active magnetic bearings; and compact, highly effective plate-fin heat exchangers.
