 pebble bed nuclear reactors

The Pebble Bed Reactor is an advanced nuclear reactor design. This technology claims a dramatically higher level of safety and efficiency. Instead of water, it uses helium as the coolant, at very high temperature, to drive a turbine directly. This eliminates the complex steam management system from the design, and increases the transfer efficiency (ratio of electrical output to thermal output) to about 50%.

The technology in various forms is under development by MIT, the South African power utility Eskom, General Atomic (U.S.), the Dutch company Romaha B.V., Adams Atomic Engines, a U.S. Company, and the Chinese company Chinergy, working with Tsinghua University.

Areva's proposed technology uses a 625 MWt "prismatic" block core (as opposed to pebble bed) with helium cooling coupled to a steam cycle (main steam temperature of 566 deg C) via an intermediate heat exchanger (rather than a "direct" helium Brayton ...
South Africa's abandoned Pebble-Bed Modular Reactor (PBMR) project still casts a shadow over the country's future nuclear energy plans, as far as the National Union of Mineworkers (NUM) is concerned.
We get very excited about (South African) innovation, but then we have struggled to get a patent to commercial development," he says, mentioning the demise of dreams over the Joule electric car, and the pebble-bed modular reactor.
The carbon allotrope is currently used primarily in the steelmaking industry but future projections tie it to increasing demand in such energy technologies as fuel cells, solar panels, pebble-bed nuclear reactors, vanadium-redox batteries and ...

Another potential demand driver is the Pebble Bed nuclear reactor. In April 2011, China started building a fourth generation 210-megawatt nuclear reactor using high-temperature, gas-cooled pebble-bed technology.

There are many uses for graphite, from lithium ion batteries to next-generation pebble bed reactors. James West: Hi, I am James West.
Another potential demand driver is the Pebble Bed nuclear reactor. In April 2011, China started building a fourth generation 210-megawatt nuclear reactor using high-temperature, gas-cooled pebble-bed technology.
Furthermore, additional demand is anticipated for use in fuel cells and the construction of pebble bed nuclear reactors. An average fuel cell vehicle will use 80 kilograms of graphite.

Lomiko optioned the Quatre Milles Graphite Property in Quebec to search for large flake, crystalline graphite which is sought after for use in electric cars, fuel cells, pebble-bed nuclear reactors. Graphene, a newly discovered, chicken-wire shaped ...
Graphite is also projected to be a key component in next-generation pebble bed nuclear reactors, which are fuelled by tennis-ball-sized graphite spheres with uranium embedded in them.
The ideal is that South Africa will one day export its own nuclear power know-how. This was the ambition of the failed Pebble Bed Modular Reactor project, and while the outcome was demoralising, South Africa's ambitions of being a nuclear energy ...
