There is often small leakage from the fuel in reactor cores. A fuel bundle is made of 64 stainless steel tubes filled with fuel pellets, each tube about 12 feet long. The tubes are held together with steel straps and forgings to make the bundle. A typical reactor has 160 to 225 of these bundles. About one third of the fuel is replaced each refueling outage and the remaining fuel is moved to a new position in the core to get an even "burn" of the fissionable material in the fuel rod. This means that most fuel rods are in the core for three cycles. Some develop pinhole leaks which are detectable via radiochemical analysis of the reactor coolant. There is no nuclear or personnel danger from this but plants usually will reduce power in the area of identified leakers to minimize the leakage. Fuel manufacturers continue to work to find designs which will not leak.

Why is decommissioning a nuclear power plant so expensive?
because they have to safetly turn of the core of the reactor and dispose of the dangeouse chemicals used
How are nuclear reactors kept safe?
There are many safety procedures put in place to keep a nuclear reactor safe, first of all control rods are used inside the reactor to stop the fission reaction running out of control and melting the reactor core, constant water(coolant) is kept pumping around the reactor cool and to help soak up some of the neutrons and x-ray scans are used to check that there are no natural cracks inside the reactor.
What is the name of India's first nuclear reactor?
India's First Nuclear Reactor was Apsara. It was also the first nuclear reactor in Asia. Apsara went critical at Bhabha Atomic Research Centre (BARC), Trombay on August 4, 1956. It heralded the arrival of India's nuclear energy programme. Dr. Homi Bhabha himself conceptualised the design of the reactor and the reactor was built entirely by Indian engineers in a record time of about 15 months.Apsara is a swimming-pool-type reactor loaded with enriched uranium as fuel. The fuel core is suspended from a movable trolley in a pool filled with water. The pool water serves as coolant, moderator and reflector, besides providing the shielding.
What is a nether reactor core?
A block that makes the nether.
To prevent fuel damage decay heat must be removed from the reactor core?
after the reactor shuts down
What is the function of reflector and reactor core?
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
What part of the reactor contains nuclear fuel?
The nuclear fuel is typically contained in the reactor core, which is a central part of the nuclear reactor where the fission reaction takes place. The fuel rods, which contain the nuclear fuel pellets, are inserted into the reactor core during operation.
Parts of nuclear reactor where nuclear fission occurs?
core
Why does the core of the reactor have a moderator?
The core of the reactor contains the nuclear fuel. Having a moderator in place within the core ensures that the nuclear fuel is processed at an accurate time duration. This can prevent serious problems from occurring within the entire nuclear reactor.
What part of the nuclear reactor is the fuel located in?
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
The core of a nuclear reactor includes?
Fissionable substances.
Where is the nuclear energy produced in a nuclear reactor?
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
What is a part of a nuclear power plant that undergoes a fission reaction?
The nuclear reactor core is the part of a nuclear power plant where fission reactions occur. Within the reactor core, nuclear fuel such as uranium undergoes controlled fission reactions, generating heat energy that is then used to produce electricity.
The part of a nuclear reactor in which the fuel is located is called the?
The part of a nuclear reactor in which the fuel is located is called the core. This is where the nuclear fission reactions take place, producing heat that is used to generate electricity.
What is layer of lead around the core of a nuclear reactor?
The layer of lead around the core of a nuclear reactor is known as the reflector. It helps to reflect neutrons back into the core, increasing the number available for fission reactions. This contributes to the overall efficiency and effectiveness of the reactor.
What is a layer of lead around the core of a nuclear reactor?
Blanket
Name one type of nuclear reactor?
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
