Sentences with phrase «further nuclear reactions»

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

Not exact matches

On 14 March, engineers decided they had to take further steps to cool the reactor vessel down, and so began pumping sea water into the vessel along with boron, an element that dampens nuclear reactions by soaking up the neutrons which drive them.

Finally, Bergeron summed up the events so far: «Based on what we understand, the reactor has been shut down, in the sense that all of the control rods have been inserted — which means there's no longer a nuclear reaction.

Because of the harsh environment fuel rods are exposed to — heat, steam, and neutrons that emanate from nuclear reactions — extensive further testing will be needed on any new cladding for use in commercial reactors, Kazimi says.

You have those, you kind of solve a lot of the blanket problems where you have your fusion blast in the center and then it hits a blanket which is basically nuclear waste, depleted waste, and there's a lot of left over energy in that waste; and you have neutrons hit that waste and then that catalyzes further reactions, you get a lot more heat.

Their aim is to gain a better understanding of thermonuclear reactions and, ultimately, how controlled nuclear fusion, which has proved remarkably elusive so far, could provide an alternative source of electrical energy.

We know now that such a transformation requires not a chemical reaction but a nuclear one, far beyond the reach of the technology of the time.
