Small modular reactors - designing nuclear energy for ...

As such, Helium gas was chosen. Fuel had to be easy to load into the reactor and easy to transport, so graphite-based fuel balls, as large as a cricket ball were chosen. The term "pebbles" was adopted for the fuel. So was born the South African PBMR Project (Pebble Bed Modular Reactor). Development of Small Modular Reactors in South Africa

The Modular Helium Reactor for Hydrogen Production ...

Abstract. For electricity and hydrogen production, an advanced reactor technology receiving considerable international interest is a modular, passively-safe version of the high-temperature, gas-cooled reactor (HTGR), known in the U.S. as the Modular Helium Reactor (MHR), which operates at a power level of 600 MW(t).

The PBMR had been designed with a Brayton cooling system in which helium travels through the reactor core and then directly into the turbine. It then returns to the reactor. The reactor outlet temperature of the helium was 940°C. This was an excellent design. The HTMR-100 – a Small Modular Reactor variant
