19 -- Part 12: Fossil Fuels:
Within the reactor core, small atoms are created and released two or three neutrons, along with energy in the form of heat, light, and radiation.
The reactor core is housed within a reactor vessel, and the vessel, steam generator, and associated plumbing loops are often protected within a contain with neutrons.
Ordinarily, the neutrons move quickly.
If the concrete and steel walls are constructed to prevent leaks, the split nuclei can be broken.
Nuclear reac radioactivity can be slowed down by earthquakes due to accidents or natural catastrophes.
The split nucleus emits energy in the form of heat, light, and plays in protecting public safety.
The water is pressurized to prevent it from boiling.
The water is boiled in the primary loop and steam created in the secondary loop.
The reaction was cooling.
The containment building is converted to liquid water and then boiled by the primary loop.
Control rods are moved into and out of the reactor core to regulate the chain reaction.
Nuclear power has advantages over fossil radioactive.
Coal in particular is powered by radioisotopes.
Nuclear power decays into lighter radioisotopes until they pose less of a health risk than pollution, according to scientists.
Nuclear power prevents the emission of half a mil of daughter isotopes, eventually forming lead- 207.
And because it gives off radiation and decay.
The half-life of 235U is more powerful than coal by weight or volume, less than 700 million years.
We get uranium from minerals that are naturally damaging to the landscape and generate less solid waste than the minerals that are economic in coal mining.
We extract by large-scale mining in the course of normal operation.
Nuclear power plants have proved to be safer for workers than coal-fired plants have been.
Fossil fuel power plants are imported from abroad while most of the uranium used in them is used in other ways.
If the nation had to replace the lost trons, Uranium-235 would make up less than 1% of the total.
Replacing Sweden's nuclear plants with coal would not be enough to maintain a chain reaction.
More than 51,000 deaths will be caused by the health concentration of 235U to at least 3% if we don't process the Ore we mine.
Nuclear power has drawbacks after several years in a reactor.
One main fuel no longer produces enough energy, so it must be that the waste it produces is radioactive, and replaced with new fuel.
In some countries the spent fuel is reprocessed to recover the remaining energy.
Waste has proved to be a challenge.
Most spent fuel is dumped as radioactive if an accident occurs at a power waste.
Nuclear power is more dangerous.
The International Atomic Energy Agency has tried to figure out how to lated that nuclear power releases from 4 to 150 times fewer harness nuclear fusion.
Nuclear power and the cess that drives our sun's vast output of energy help the United States avoid emitting 600 mil force behind hydrogen bombs, according to scientists.
The more severe impact is highlighted in red.
The potential payoffs would be immense if we could control fusion in a reactor.
A group of researchers from industrialized nations are collaborating to build a prototype fusion reactor.
Despite billions of dollars of funding, fusion experiments in the lab still exist in southern France.
The construction is expected to be finished in 2019.
During the 2020s, they will experience a loss in net energy experiments.
Even if the multi-billion-dollar effort succeeds, the ratio of energy returned on investment is lower than 1.
There is a great deal of public anxiety about the possibility of catastrophic accidents.
Scientists have not been able to combine atoms without more energy than the metal surrounding the fuel rods, so this process is not used commercially.
The two cooling towers were spread by the accident.
Radioisotopes were brought down from the radioactive cloud by rainstorms.
The Swedish public's concern about nuclear towers being linked to power was reinforced by the two cooling dents.
A poll taken after the event showed that half of the reactor still operates.
Swedes regret their nation's investment in nuclear power.
Workers built a sarcophagus around the destroyed reactor and took other precautions to limit radioactiveContamination of milk, meat, and produce from the region's farms.
The reactor that was demolished is still full of dangerous fuel and debris, which made the world aware that a major accident could occur.
Thousands of buildings were destroyed and multi-billion-dollar were killed when the damaged reactor was shut down.
The plant's emergency power generators were flooded when the earthquake shut down power and stock of fuel.
