The nuclear reactions are used to produce heat, which will vaporize the moderator and thus producing some steam. That steam is then used to make turning a dynamo, producing electricity (a nuclear plant can thus be seen as a weird steam machine). The fission reaction produces an energy of 202.8 MeV. The heat capacity of 1 mol of water is 75.385 J/K. 1) How many fission reactions are needed in order to increase the temperature of 1 mol of water from 65 degrees Fahrenheit to 232 degrees Fahrenheit? 2) Deduce from the previous question that one nuclear reaction allows vaporizing several water molecules. 3) What is the consequence of this effect for the total volume of the reactor? Is it mostly filled with fuel or water?

9 H the mass of the products in a fission reaction is 3.2 x 10^28 kg less than the reactants, how much energy is released in the reaction? (A) 3.6 10 45J (B) 1.1 x 10-38J (C) 9.6 x 10420 J (D) 2.9 x 10-11 J

A proposed nuclear reactor facility will have an electrical power output of 908 MW with a 31.3% efficiency in converting nuclear to electrical power. Assuming the average fission reaction produces 234 MeV, how many reactions will take place at the facility every second?

Uranium-235 is used as a nuclear fuel for Canadian made CANDU nuclear power plants. During one such fission reaction, a uranium-235 atom is split by a fast moving neutron to produce krypton-92, barium-141 and an unknown number of neutrons. Determine the number of neutrons produced by this reaction, record that value in blank #1. Determine the energy released by the reaction, rounded to the nearest whole MeV, record that in blank #2.
