pebble bed उदाहरण वाक्य

उदाहरण वाक्य

1. Comparison of the neutron spectra of the helium cooled pebble bed ( HCPB ) blanket of a fusion DEMO reactor, with different planned or existing neutron sources including IFMIF [ 6 ], [ 7 ] .-->
2. Kemal Turkaslan, head of the Ankara-branch of the construction engineers association said the construction code requires that no stone bigger than a pebble be used _ but grapefruit-sized stones were spread around the site of the collapsed dorm.
3. The document begins, " Exelon Corp . believes that we have found a technology that possesses the characteristics necessary to successfully compete in a deregulated environment in the Pebble Bed Modular Reactor ( PBMR ), a design under development in South Africa ."
4. The design concept of using thermal expansion to stabilize a reactor core has since been featured in other reactor designs, notably in the pebble bed reactor which is however neither a fast neutron reactor nor a breeder reactor, and in subsequent Fast breeder reactors.
5. A 400 MWth pebble bed modular reactor demonstration plant was designed by PBMR Pty for deployment in South Africa but withdrawn in 2010, and a consortium of Russian institutes is designing a 600 MWth GT-MHR ( prismatic block reactor ) in cooperation with General Atomics.
6. With an earlier focus on South Africa's Pebble bed modular reactor, in 2012 Idaho National Laboratory approved a design similar to Areva's SC-HTGR ( formerly Antares ) reactor as the chosen Next Generation Nuclear Power Plant HTGR to be deployed as a prototype by 2021.
7. One possibility is the " pebble bed " design, which would circulate uranium fuel shaped like billiard balls through the reactor, and generate only about one-tenth as much heat per square foot as a conventional reactor; as a result, supporters assert that it can not experience meltdown.
8. The THTR-300 was a helium-cooled high-temperature reactor with a pebble bed core consisting of approximately 670, 000 spherical fuel compacts each in diameter with particles of uranium-235 and Fort St . Vrain reactor in the USA, in that the reactor coolant transferred the reactor core's heat to water.
9. Some, such as the pebble bed reactor, passively slow down the chain reaction when coolant is lost; others have extensive passive safety systems ( such as a large thermal heat sink around the reactor core, passively-activated backup cooling / condensing systems, or a passively cooled containment structure ) that mitigate the risk of further damage.
10. It's too early to jump to conclusions about the merits of pebble bed reactors, warns David Lochbaum, a former nuclear safety engineer who now works for the Union of Concerned Scientists in Washington, D . C . To date, " no ( fully operational ) reactor like that has ever operated anywhere on the planet ."
