In February, Pebble Bed Modular Reactor (PBMR) Ltd., an eponymously named South African company announced a major change of strategy. After 10 years of development it said it was abandoning plans to ...

China’s HTR-PM (High Temperature) modular pebble bed reactor has finally started commmercial operation. It has two small reactors (each of 250 MWt) that drive a single 210 MWe steam turbine. It uses ...

It is a pebble bed high temperature gas reactor. All the components of the compact design would be packaged in a single shipping container, making rapid deployment to remote locations or for disaster ...

Although the concept of nuclear fission is a simple and straightforward one, the many choices for fuel types, fuel design, reactor configurations, coolant types, neutron moderator or reflector ...

In the Shidao Bay test, two pebble-bed reactors connected to a 210-MWe steam turbine moderated their own nuclear reactions and safe temperatures were maintained, with the core shutting down in ...

An illustration of the inside of a pebble bed reactor. Argonne National Laboratory Another popular option is called a pebble bed reactor, which involves a series of graphite pebbles about the size ...

The Pebble Bed Modular Reactor (PBMR), a South African technological triumph that was muscled out of the energy discussion in 2010 under former president Jacob Zuma’s presidency, is getting a ...

The new Chinese plant uses an innovative design called a "pebble-bed reactor” to mitigate the risk of meltdown. Unlike most reactors that use water to cool down, it uses helium gas, which can ...

The Xe-100 is a 200MWt Advanced Pebble Bed Reactor that will be deployed in Washington State in the 2028 timeframe with the support of the US DOE Advanced Reactor Demonstration Program.

This is not a design that can be retrofitted to existing nuclear fission plants, however, because it involves a new paradigm called a pebble bed reactor. The team’s findings appear now in the ...
