When a reactor has burned enough of its fuel that it cannot be made to go critical by pulling all the control rods all the way out, it has reached the end of its useful life. There is a lot of unburned fuel left in the fuel elements, but not enough to achieve criticality the way the reactor core is set up. (Only a small percentage of the fuel is actually burned.) Usually the operators of a nuclear plant will take a reactor out of service and refuel it a bit before this. And military reactors will be taken offline sooner and refueled because of the requirement that the reactor be able to be brought critical at what is called the "peak xenon" point. Generally speaking, the core is removed and put in a storage pool that provided cooling and shielding. The core will remain there until it can be disassembled into fuel bundles and the bundles packed up and moved to a long-term storage facility for a century or a few. It is unusual that the fuel elements are reprocessed to remove the remaining fuel because of the presence of a lot of extremely radioactive fission fragments.

How many years is the useful life of a nuclear fission reactor?
The useful life of a nuclear fission reactor is typically around 40-60 years. However, this can vary depending on factors such as maintenance, upgrades, and regulatory approvals.
How long are the fuel rods typically left in the reactor core in a BWR or a PWR?
The length of time we see fuel rods left in the core of a reactor will depend on the time it takes to deplete the nuclear fuel in those rods. Reactor design, specifically fuel rod design, and the rate at which the fuel is consumed during operation all have an effect. Typical life of the fuel in a nuclear reactor at a power station is several years.
What is the function of shielding in a nuclear reactor?
The first line of shielding is to limit the neutron bombardment of the pressure vessel, to give it a safe life of 40 or more years. Then you need to protect personnel who have to go into areas close to the reactor for maintenance, and also to limit the exposure of equipment which may need maintanance done during the life of the plant
What happens to remainig neutrons after consumption of all the Uranium in uncontrolled Nuclear fission reaction?
Basically, there are two things that can ultimately happen to neutrons. Either they get absorbed into the nucleus of an atom, or they undergo radioactive decay. In a fission reactor, neutrons typically last only microseconds, with the life expectancy depending on conditions. A free neutron, outside the reactor, has a half life of 886 seconds, or a little less than fifteen minutes. During its lifetime, it could travel quite far, but the likelihood of a neutron getting out of the reactor is extremely small, so small that it is discounted as an event rare enough not to warrant concern.capturedescapestriggers fission
What happens from the sun's nuclear fision?
Not much to speak of. There is no significant amount of nuclear fission going on in the Sun.

Nuclear reactor work useful and harmful point?
Produces power efficiently. Very expensive and difficult to decommision at end of life.

What happens in a nuclear change?
it does nothing but then it affacts the half life
How long does a nuclear reactor last?
The lifespan of a nuclear reactor can vary depending on factors such as maintenance, regulatory approvals, and upgrades. Typically, commercial nuclear reactors are designed to operate for 40-60 years, with some being granted license extensions to continue operating beyond their initial design life. After this period, decisions must be made about either decommissioning the reactor or investing in further upgrades to extend its operation.

What happens if your health reaches 0?
If your health reaches 0 you are dead and you will lose a life. If you lose all of your lifes you are defeated and its game over for you.
What are uses for nuclear reactions?
Nuclear reactions are used in nuclear power plants to generate electricity, in nuclear weapons for military purposes, in medical imaging and cancer treatment, as a power source for spacecraft, and in food irradiation to kill bacteria and increase shelf life.
What happens to the nuclear membrane as the cell progresses through prophase?
disappear you go do yourself and freaking get a life!
What are some uses of nuclear energy?
Nuclear fission produces nuclear waste which has to be desposed off and because of the nuclear waste's long half-life it takes thousands of years before the waste becomes safe. Mining for U-238 is expensive and an enrichment process is required to turn U-238 to U-235 before it can be used in a nuclear reactor, this takes time and money and is another disadvantage.
How is energy linked to the sun?
The sun, like all stars, gets its energy from nuclear fusion. The Earth is only habitable for life because of the sun's radiant energy which reaches us. So we all depend on nuclear energy.
What happens after my Prudential term life policy reaches its expiration?
A Term Life Insurance policy ends when it reaches the end of the term period and does not have any accumulated value. You may have to do some paperwork depending upon your particular insurance policy and its specific provisions.
