who we are
Pebble Bed Modular Reactor (SOC) (PBMR ™) was established in 1999 with the intention to develop and market small-scale, high-temperature reactors both locally and internationally.
The PBMR is a helium-cooled, High Temperature Reactor (HTR).  Very high efficiency and attractive economics are possible without compromising the high levels of passive safety expected of advanced nuclear designs.
what is PBMR ™?
The PBMR essentially comprises:
A steel pressure vessel which holds the enriched uranium dioxide fuel encapsulated in graphite spheres.  The system is cooled with helium and heat is converted into electricity through a turbine.
The plant comprises a module building with the reactor pressure vessel (RPV) and the power conversion unit (PCU).
why PBMR ™?
Safe, clean, cost-competitive, versatile, adaptable, and green energy.  These, in a nutshell, are the features of South Africa's Pebble Bed Modular Reactor (PBMR).
project status
From a small nuclear engineering company with barely 100 employees at its inception in 1999, Pebble Bed Modular Reactor (SOC) (PBMR) has grown into one of the largest nuclear reactor design and engineering companies in the world by 2004. In addition to the core team of some 800 people that were at the PBMR head-office in Centurion near Pretoria, more than a 1000 people at universities, private companies and research institutes were involved with the project.
Pebble Bed Modular Reactor (SOC) is a public-private partnership comprising the South African government, nuclear industry players and utilities. The PBMR was clasified as a strategic national project due to its significance to South Africa and its potential in international markets, as a prospective provider of safe, clean energy.
  "The South African PBMR technology is the leader in the world for generation IV type reactor and a leader in HTGR fuel developments."  
  how safe is PBMR ™?  
  The PBMR has inherently safe features as a result of the design, materials used, fuel and physics involved.  
  This is why, should a worst-case scenario occur, no human intervention is required in the short or medium term.
