Basing their design primarily on the HTR-MODULE, the Pebble Bed Modular Reactor (PBMR) is being developed for commercial use by an international conglomerate of U.S. based Exelon Corporation, British Nuclear Fuels Limited, and South African based ESKOM . Their initial objective is to develop a 116.3 MWe demonstration reactor and start construction in Koeberg, South Africa around mid-2005.
Develop a sufficient technical and economic basis for this type of reactor plant to determine whether it can compete with natural gas and still meet safety, proliferation resistance and waste disposal concerns. What is a Pebble Bed Reactor? 360,000 pebbles in core about 3,000 pebbles handled in FHS every day
There are approximately 370,000 pebbles in a pebble bed reactor. One tennis ball sized pebble comes out the bottom of the reactor every 30 seconds. It can be returned to the top of the reactor for additional use.
X-energy is developing Generation IV high temperature gas-cooled reactors and the fuel to power these reactors. Our innovative solution will deliver energy that is clean, safe, secure and affordable. X-energy is leading the path forward to a clean energy future.
The Pebble Bed Modular Reactor (PBMR), like most new reactor ideas, is a reincarnation of an old reactor idea. In this case the old idea is the "high temperature gas reactor" or HTGR, that then was proposed in a modular version, known as the MHTGR. The PBMR is a variant of the HTGR.
The pebble-bed reactor (PBR) is a design for a graphite-moderated, gas-cooled nuclear reactor. It is a type of very-high-temperature reactor (VHTR), one of the six classes of nuclear reactors in the Generation IV initiative .
