3. Currently, 20% of the US energy is generated using nuclear reactors.

a. Briefly describe the fission process.

b. Describe how this is used to generate electricity for our homes.

c. List the hazards associated with nuclear energy.

Expert Solution

a. Nuclear ﬁssion is a process where the nucleus of an atom is split into two or more smaller nuclei with large amount of heat is released. When an Uranium-235 isotope is bombarded with a neutron it release a total of 3 neutrons and strontium, xenon stable elements with release of heat energy equivalent to 200 MeV (Million electron volts).

²³⁵₉₂U + ¹₀n --> ⁹⁵Sr + ¹³⁹Xe + 2 ¹₀n + 180MeV

b. Heat produced during nuclear fission to used heat water to convert as steam. The steam is used to spin large turbines that generate electricity. This electricity is supplied to homes through power grid transmission.

c. The radio active isotopes produced during fission continuously emits radio active particles. Exposure to radioactive fallout would lead to an increased risk of genetic disorders, cancer and leukemia. The Fukushima Nuclear Disaster is the latest disaster in Japan.

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the...

Nuclear fission and electrical energy Electrical energy currently produced by nuclear reactors is derived from the decay of 235 92U, through a process known as nuclear fission, whereby a slow-moving neutron is captured by the 235 92U nucleus, creating 236 92U. The uranium nucleus 236 92U is very unstable, and it will immediately decay into two lighter elements and release neutrons. Some of the neutrons will go on to destabilize other nuclei, creating a chain reaction. During fission reactions the...

Nuclear fission reactors consist of three main components: the fuel rods, control rods and the moderator. Draw a diagram of typical reactor and give a brief description of each of the main components. Why are fusion reactors considered ‘cleaner’ than fission reactors?

Nuclear fission is the splitting of an atom and the process emits enormous amounts of energy. When uranium is bombarded by a neutron the reaction results in barium, krypton, three neutrons and energy. The three neutrons are produced in the reaction play a critical role in nuclear energy. Why is it necessary that each fission event produce more than one neutron to sustain the chain reaction discussed above? What role do these neutrons play in an atomic bomb? Please use...

A promising source of energy are nuclear fusion reactors (more stable and with less radioactive products than fission reactors). Their basic reaction is the fusion of two forms of heavy hydrogen into helium and a neutron: d + t → 4He + n. The deuteron (d) consists of a neutron (n) and a proton (p) bound by 2.2 MeV , the triton (t) of 2 n’s and a p bound by 8.5 MeV , and 4He of 2 n’s and...

Fission reactions are induced in nuclear power plants because they produce great amounts of energy. Often, a nucleus must be forced to undergo fission by being hit by another particle. A U-235 nucleus being hit with some other particle causes it to undergo fission and emit more particles. Those particles eventually hit other U-235 nuclei, which propagates the reaction. What is this type of reaction called? A. Chain Reaction B. Alpha Reaction C. Gamma Reaction D. Fusion Reaction

Most of the energy released in nuclear fission is electrostatic. Suppose a uranium-236 nucleus (92 protons and 236-92=144 neutrons), which is initially at rest, splits into two identical “daughter” nuclei each having 46 protons and 72 neutrons. (Protons and neutrons have the same mass, namely 1.67×10-27 kg.)(a) [15 pts.] Initially the two daughter nuclei are separated by 13×10-15 m. How fast will they be moving when they get very far apart?(b) [5 pts.] Fission products usually are not the same...

According to the Department of Energy (DOE), 99 U.S. reactors have generated 805 billion kilowatt hours of electricity in 2016. That is 20% of the U.S. energy generated that year and enough to power 73 million homes. How many tonnes (metric tons) of natural uranium have the U.S. needed that year? In your calculations, ignore the energy gained from the fissioning of Pu239 produced from the fertile U238 (i.e., assume all the energy generated from the fissile U235). Also ignore...
