Which material is commonly used as a burnable neutron absorber in nuclear fuel? Cadmium Boron Zircaloy...
Control rods in a nuclear reactor are often made of cadmium because it absorbs neutrons. Part A Write the nuclear equation in which cadmium-113 absorbs a neutron to produce palladium-110 and an alpha particle. Express your answer as a nuclear equation.
Tetraboron carbide, B4C, is a very hard substance used for grinding purposes, ceramics, and armor plating. Because boron is an efficient absorber of neutrons, B4C is also used as a protective material in nuclear reactors. The reaction that forms B4C from boron(III) oxide, B2O3, is 2 B2O3 + 7 C → B4C + 6 CO (at 2400°C) (b) What is the minimum mass of carbon, in grams, necessary to react completely with 24.720 g of boron(III) oxide, B2O3? (d) What...
18. Which of the following symbols represents a neutron in nuclear chemistry? a. 11 p b. 0-1 e c. 42 He d. 10 n
Nuclear grade Uranium is the key material used in nuclear reactors. In order to understand the property of Uranium isotopes scientists use an equipment which is called Mass Spectrometer. They injected a uranium iron beam with a speed 3.00 x 105 m/s into a 0.6 T magnetic field. Beam velocity and the magnetic field are perpendicular each other. Calculate the separation between impacts points for two isotopes which have masses 3.9508 x 10-25 kg and 3.901 x 10-25.kg. Assume the...

Nuclear (Please show work) 9) Which one of the following is a reason for neutron flux shaping in a reactor core? A. To minimize local power peaking by more evenly distributing the core thermal neutron flux B. To reduce thermal neutron leakage by decreasing the neutron flux at the edge of the reactor core C. To reduce the size and number of control rods needed to ensure the reactor remains subcritical following a reactor trip D. To increase differential control...

Problem 1 An absorber-stripper process is used to remove carbon dioxide (CO2) and hydrogen sulfide (H2S) from a feed (stream 1) consisting of 25% CO2 and 15% H2S in nitrogen. In the absorber, a solvent selectively absorbs hydrogen sulfide and carbon dioxide. The absorber overhead (stream 2) contains only 2% CO, and the balance Nitrogen with no Hys. Ny is insoluble in the solvent. The rich solvent stream leaving the absorber (stream 3) is flashed in a flash separator: the...
