A
"reactor" is a device or structure that helps create and control a reaction, usually a chemical or nuclear reaction. It can be thought of as a container or system designed to initiate and manage a specific process or change.

Now, the group has started running eerie TV ads against plans for new
nuclear reactors in two southern states.
At present, 30 countries include nuclear
reactors in their power portfolio.
The nuclear industry has been working to lower the cost
of reactors for over a half century but the price has only risen.
Only one of the ill - designed
reactors at the site exploded in 1986.
For the very long term, recycling the fuel of
fast reactors would be so efficient that currently available uranium supplies could last indefinitely.
This is a legitimate concern but I think it is being dealt with with in
newer reactor designs.
And it won't happen so long as large and expensive light -
water reactors remain our only option.
It is designed as a modular
reactor for factory fabrication, and could be used for electricity production and industrial process heat generation.
Specifically it covers particle interaction with the metals and alloys used in nuclear
reactor cores and hence subject to intense radiation fields.
The «spent fuel» is easily radioactive enough to kill with a short contact exposure many years after removal
from reactors.
With all due respect to your efforts and experience, no one is suggesting new 50 - year old
reactor builds.
And he says there's logic to pressing forward on a new generation of
reactors with more safety features.
In early studies, scientists relied on calculations or other indirect means, such as electron spectrum measurements made on
reactor fuels, to estimate these numbers.
When auxiliary batteries were exhausted, the plant was without power to continue
cooling reactor cores and spent fuel pools.
Over the past week, countries around the world have announced plans to check the safety of
operating reactors and rethink nuclear power policies.
Investing in advanced fuels research is critical to developing a new nuclear
reactor technology.
Some fast
reactors use oxide fuels, but those made with metallic fuel are even faster, since oxygen is a fairly light atom.
No one has ever died as the result of radiation due to
commercial reactors in exactly the same way as no one has ever died of lung cancer due to cigarette smoking.
Making a bigger diamond is hard — it might crack as it grows, and you need more material to start it and a
larger reactor.
But a major effort to develop
such reactors does not guarantee they will suddenly become economically competitive.
Most of us have lived our entire lives as
first reactors instead of first responders.
It can be adapted to recycle spent elements from
other reactors, turning nuclear waste from a liability into an asset.
After a 30 - year hiatus, there is a greater push for more nuclear power plants, with 22 new
reactors under review.
In the past it was felt that you get an economy of scale by building a very big nuclear
reactor because of permitting and other issues.
Used fuel is currently stored at
reactor sites around the country.
In general, these plastics can be manufactured using
existing reactors and processed using existing equipment.
Dangerous nuclear weapons proliferation increasing the chance of nuclear war
if reactors are used to produce weapons; 2.
Steam continues to rise in the spent fuel pool at
reactor No. 3, indicating that at least some water is reaching the hot rods.
To learn about the most common
reactor types, scroll below the graphic.
Solar reactors don't need the big turbine or generator for making electricity, but only consist of a tower, a solar field, a receiver and the reaction chamber.
The cable trench there contains much more radiation than those in the other three damaged
reactor units.
Although
thermal reactors generate heat and thus electricity quite efficiently, they can not minimize the output of radioactive waste.
We found out that his father was the one half to the ultimate
arc reactor.
A new generation of
reactors after more than 30 years without a new nuclear plant raises hopes, opportunities and concerns.
This could in turn lead to environmentally friendly, efficient, chemical
reactors based on cellular molecular machines.
