The nuclear fission process produces a range of lighter elements as fission products, and many of these are radioactive.
We generally consider nuclear fission as the "splitting" of atoms. In this process, a large atomic nucleus splits into two smaller nuclei. The smaller nuclei are called fission fragments, and they are radioactive. Making nuclear energy, which we do in nuclear reactors, results in the production of large quantities of highly radioactive fission products. These byproducts require that we cool the spent fuel for long periods, and also that we store it for centuries so that the radioactive materials have a chance to decay and become less hazardous.
Nuclear energy generates radioactive waste in the form of spent nuclear fuel, which contains radioactive isotopes. This waste must be stored and managed properly due to its long-term hazardous nature.
The present tense of "spent" is "spend."
I/You/We/They have spent. He/She/It has spent.
Radioactive decay of spent fuel refers to the process where the radioactive isotopes in the fuel break down and release radiation and particles. This decay can continue for thousands of years, making spent fuel a long-term radiation hazard. Proper storage and disposal methods are necessary to prevent environmental and health risks.
I spend
It is highly radioactive (that is the waste contained in the spent fuel)
spent
Spent is a past-tense verb. The present-tense form of spent is spending. The future-tense form of spent is will spend. Hope this helps!
spend is the base verb spent is the past form spent is the past participle spending is the present participle
