How Is Nuclear Energy Produced to Generate Electricity

What is the most technically challenging part of using uranium to generate electricity? A)mining and milling the radioactive material,because of environmental regulations B)separating the uranium from the rock in which it occurs C)using gas centrifuges to preferentially enrich the more energetic uranium isotope (²³⁵U) D)finding a material to moderate the reaction within the reactor

Which of the following is NOT an environment issue associated with nuclear energy? A)uranium mining and milling can contaminate water and land B)fuel rods are stored on site and so pose a risk of radioactive contamination C)Yucca Mountain,the designated repository for spent fuel rods,had a large nuclear explosion D)the Chernobyl nuclear reactor in the Ukraine had explosions and a reactor meltdown and killed at least 56 people
