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.
To prevent fuel damage decay heat must be removed from the reactor core?
after the reactor shuts down
What is a nether reactor core?
A block that makes the nether.
Where is the nuclear energy produced in a nuclear reactor?
In the core.
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 a nuclear reactor would most likely contain plutonium?
This part is the core of the nuclear reactor containing the nuclear fuel.
The core of a nuclear reactor includes?
Fissionable substances.
What is in the core of a nuclear reactor?
The core of the nuclear reactor includes:nuclear fuel elements (composed of the fuel meat covered with cladding)reactor coolantreactor moderator (for thermal reactors)control elementsmeasuring instrumentsstructural and support structures
What is layer of lead around the core of a nuclear reactor?
Blanket
The part of a nuclear reactor in which the fuel is located is called the?
core
What is a layer of lead around the core of a nuclear reactor?
Blanket
What is the place where controlled nuclear fission reactions take place?
In the core of a nuclear reactor
In what part of a nuclear reactor is the fuel is located?
Fuel in a nuclear reactor is located in the core of the reactor. It is there that the fuel, which is sealed (welded) inside plates or tubes, is situated in fuel bundles.
What are fuel cells in a neclear reactor?
Fuel cells are an important part of a nuclear reactor. The component that powers the nuclear reactor is the reactor core and the fuel cells are found inside and hold uranium dioxide.
