If a reactor cannot be properly controlled, it will quickly overheat. This is what happend at Chernabyl, Russia. The fuel rods melted into the reactor floor and released a large plume of radio-active steam. The way to immeidatly shut down a reactor is a S.C.R.A.M.(Safety Control Rod Axe Man). A reactor has control rods that exorb radiation and stop the reaction when lowered onto the fuel rods. The first reactor had a rope holding up the control rods. A guy with an axe would chop the rope if the reaction got out of control. Another is shielding. The core is surounded with lead and concrete that shields people from the radiation from the reactor.

Waves that do require a medium are called?
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
Do mechanical pencils use energy?
Mechanical pencils themselves do not need any energy in the forms of battery or electricity. However, mechanical pencils do need human energy to work. We need to add lead and push lead out; they do not do this on their own.
How are nuclear reactors used in nuclear reactors?
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
How many of the reactors exploded?
During the Fukushima Daiichi nuclear disaster in Japan, three of the reactors experienced hydrogen explosions. These explosions occurred in Reactors 1, 3, and 4.
What are the three main advantages of a fusion reactor compared to a fission reactor?
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.
You need a mechanical projects?
yes i need a mechanical project yes i need a mechanical project
What is the efficency of a nuclear power plant?
Mechanical and heat losses in the generating plant aside, the current generation of Light Water Reactors is about 33%. Newer technologies such as Supercritical Water Reactors can reach efficiencies of up to around 45%.
What is the subject in this sentence for what reasons are these rhinos in need of protections?
Rhinos
What is the science that deals with nuclear energy?
We see nuclear physics, which is a branch of physics, that deals with nuclear energy.It could be argued that in a broader sense we need help from mechanical engineers, which is a branch of engineering, to pull it all off. Mechanical engineering is tested to its limits in the design of the plumbing systems of nuclear reactors, like the pressurized water reactor.
What rhymes with reactors?
factors rhyme with reactors tractors rhyme with reactors actors rhyme with reactors
How are nuclear reactors useful?
They produce electrical energy. Humans need a lot of that.
Why we need mineral?
you need minerals or you will become fat , disabled and morbatly obese . minerals are reactors for vitamins and minerals
Do fusion powers nuclear reactors?
No. Our reactors are fission reactors. We haven't yet mastered fusion reactors for power.
Does the bill of rights provide all the protections you need for your life liberty property?
D
What is the need of reactors at capacitor bank?
In the power system, reactors and capacitors banks are used for VAR support (basically to push up or pull down the system voltage). In circuits, capacitors and reactors are used for isolation, filtering, coupling, biasing, oscillating, and the list goes on and on.
Why cant saltwater be used in nuclear reactors?
possibility of corrosion.actually naval ship & submarine reactors are designed to use seawater as emergency coolant. they need significant repairs afterwards, but they would certainly need even more repairs if they overheated due to a LOCA.
How many different types of nuclear reactors are there?
There are several types of nuclear reactors, with the most common being pressurized water reactors (PWRs) and boiling water reactors (BWRs). Other types include heavy water reactors (HWRs), gas-cooled reactors (GCRs), and fast breeder reactors (FBRs). Additionally, there are specialized reactors like research reactors and small modular reactors (SMRs). In total, there are more than a dozen distinct reactor designs used for various purposes worldwide.
