Question
Uranium-235 is considered ideal for nuclear reactors due toa. its wide distribution as a resourceb. its stable nature as an isotopec. its high EROEId. its minimal production of radioactive wastee. its fissionability
Solution
The ideal nature of Uranium-235 for nuclear reactors is primarily due to its fissionability (option e). Uranium-235 is one of the few materials that can undergo induced fission, meaning a neutron can easily split its nucleus. This property makes it ideal for nuclear reactors, where the fission process is used to generate heat, which is then used to produce electricity.
While Uranium-235 is widely distributed (option a), it is not the most abundant isotope of uranium. In fact, it only makes up about 0.72% of natural uranium, with the rest being mostly Uranium-238.
Uranium-235 is not particularly stable (option b). Its half-life is about 700 million years, which is relatively short in comparison to other isotopes like Uranium-238, which has a half-life of about 4.5 billion years.
The Energy Returned on Energy Invested (EROEI) of Uranium-235 (option c) is high, but this is not unique to this isotope and is a characteristic of nuclear power in general.
Finally, the use of Uranium-235 in nuclear reactors does produce radioactive waste (option d), although the amount and type of waste can vary depending on the specific design of the reactor and the fuel cycle used.
