Not exact matches

The agreement was that if North Korea (and others) joined, they would be given access to peaceful uses for nuclear reactions (see here).

Nuclear reactors often use deuterium oxide to control reactions, because the liquid slows down neutrons without capturing many.

It could also find use in stock market predictions and complex scientific simulations of random processes, such as biological interactions or nuclear reactions.

Steve Mirsky: And you talk about how it's possible that because neutrinos are an inevitable byproduct of nuclear reactions, they could be used to figure out if somebody is running nuclear facilities on the sly.

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.

But there's no doubt that you can trigger nuclear reactions using chemical energy.»

Today's nuclear power plants use the heat from uranium fission reactions to do nothing more complicated than boil water, making pressurized steam that spins turbines to generate electricity.

Circular cracks had formed around several of these steel nozzles in the corroded lid that shield the control rods — 20 12 - inch -(30 - centimeter --RRB- long sticks made of a silver — indium — cadmium alloy that are used to dampen or shut down a nuclear reaction — rendering them vulnerable to simply popping off.

The samples were then analyzed with a technique called polymerase chain reaction (PCR), used to amplify specific nuclear «microsatellites» for statistically measuring gene flow between the different populations and subpopulations located in the western South Atlantic (Breeding Stock A) and the eastern South Atlantic and Indian Ocean populations (Breeding Stocks B and C, and the Arabian Sea humpback whale population, respectively).

But Bickford says some researchers have proposed that a smaller supply of antiprotons, comparable to the population of the belt, could be used as a catalyst to trigger nuclear reactions that would release charged particles.

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.

The essence is that the stars are on the main sequence during most of their life time and «burn» hydrogen in this time («burning» is an often used word here; in reality it's not a chemical reaction, but a nuclear reaction: hydrogen nuclei are fused to helium nuclei).

An American research team in January discovered a way to initiate nuclear fusion reactions in a process called «fast ignition» by using a high - intensity laser, according to the American Association for the Advancement of Science.

As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets used up.

«Subsequently, because of his conviction that if a nuclear chain reaction could be made to work it might be used as an instrument of war to set up violent explosions, Szilard separated that part of the application which related to the nuclear chain reaction and incorporated it in modified form into a later filed application, No. 19157, which he assigned to the British Admiralty in order to prevent its publication.

For commercial use, 192Ir is produced in a nuclear reactor by reaction of 191Ir with neutrons.

If students reveal in an interest inventory that they enjoy working with digital media, leverage that interest in a science class by using new media to build content literacy — for example, what about Einstein's greatest hits playlist, a digital story about nuclear fusion, a video game that simulates a chemical reaction, or a web page that illustrates the formation of the earth?

The heat used to boil water can come from burning of a fuel, from nuclear reactions, or directly from the sun or geothermal heat sources underground.

Nuclear power plants, however, heat the water using fission reactions, splitting atoms of uranium or plutonium and producing no carbon emissions.

The basic principle behind a nuclear reactor is simple: the heat produced by a controlled nuclear reaction is used to create steam pressure that drives a power - generating turbine.
