The atomic reactor generates enormous amounts of thermal energy.
Now the pebble bed reactor has the same basic safety features as a high temperature prismatic reactor in a sense that it has a meltdown free core.
One of the key factors in this scenario is determining how the reactor will be shut down because you must shutdown the reactor.
The unit, including the alloy, the reactor and fuel cell might weigh less than 100 pounds.
The quality model of the pilot phase reflects, over the run length of a reactor run, what we anticipated.
Three reactor units at the Onagawa plant are being watched and controlled for radiation leaks and possible meltdown.
The discovery was made even as it emerged that the no 3 reactor was not likely to have been breached, as feared earlier.
A small group of countries with advanced nuclear technologies would co-operate to develop new reactor designs and waste-handling methods, reducing proliferation risks.
On Thursday morning, Japan's Self-Defense Forces started dumping water from a helicopter on reactor No. 3, making four passes. They planned to do the same for No. 4 sometime Thursday.
An agreement between Poland and the three Baltic countries to build a nuclear-power plant on the site of a former Soviet reactor in Lithuania has not yet been signed.
A reactor is a container for chemical reaction.
Effect factor of CO2 conversion rater in urea reactor is analyzed, the application and result of using the new high efficient urea reactor internals is introduced.
A surge of power caused a chain reaction that set the reactor core on fire.
New types of reactors were designed, including the Fast Breeder reactor powered by plutonium and cooled by liquid sodium.
a highly fissionable isotope of plutonium that is used in atomic weapons and as a reactor fuel; produced by irradiating uranium 238 with slow electrons.
As soon as the earthquake struck, the reactors scrammed: the control rods, used to modulate the speed of the nuclear reaction, were inserted into the reactor cores, shutting off the nuclear reactions.
How do you typically cool a reactor?
And they have an operating pebble bed reactor now, they have a small research reactor and it's being proposed in South Africa.
Residents living near a nuclear facility have been evacuated from the region of its overheated reactor.
Not having sanction and not having built the required safety requirements did not stop them form initiating the Chernobyl reactor.
They know that if there is a reactor meltdown it could be a major disaster affecting huge areas and massive Numbers of people, and they are risking their lives to try and prevent that.
Our first atomic reactor was built in 1958.
Backlash from the reactor is likely to be an even bigger problem when the water inside the reactor is much more radioactive than usual and is under extremely high pressure.
The Sandia prototype's solar collector has an area of about 20 square meters (215 square feet) for a reactor the size of a beer keg, Stechel says.
The active reactor zone is a laying of graphite blocks with cylindrical fuel apertures.
For a nuclear reactor to be licensed in Canada its operators have to provide a "safety story" for the Canadian nuclear safety Commission (CNSC).
The bubbling gas causes turbulence and circulates the algae around the reactor.
Another type of high temperature gas reactor is what we call a pebble bed reactor.
Ultimately ending up with a group of thermalized neutrons that also have a certain probability of leakage from the reactor.
This is where having a negative PCR is handy, because it automatically limits the number of neutrons flying through the reactor, so it damps itself down after a momentary power increase.
