How many neutrons are needed to initiate the fission reaction shown? 137 97 40 92 Number neutrons
4. a. Assume all the energy in a nuclear reactor comes from the fission of 239Pu (assume 200 MeV/fission). How many fissions per second are required to maintain a power level of 3400 MW? b. How many grams per day are fissioned in this reactor?
Which of the following explain why the critical mass of 239Pu is significantly smaller than that of 235U when used as a reactor fuel? 239Pu is more massive than 235U235U. 239Pu produces more neutrons per fission. 239Pu is easier to fission by thermal neutrons.
Find the number of neutrons released by the following fission reaction. 1 0 n + 235 92 U ? 117 50 Sn + 101 42 Mo + neutron(s)
1. Consider the induced fission of 235U to form 2 fission fragments, 2 prompt fission neutrons with a total kinetic energy of 5.2 MeV, and 7 prompt gamma rays with a total energy of 6.7 MeV. The reaction is shown below: 96x after 139 95 235 ー→ 542 For the specified fission reaction, calculate the following: (a) The prompt energy released for this fission event in MeV (b) The initial kinetic energy of the 140Xe' fission fragment in MeV 1....
3. A fission chain reaction. a. A neutron can cause 235U to fission, producing two daughter nuclei (tin and molybdenum) and three more neutrons. These three neutrons can then, in turn, cause three more 235U nuclei to split. One typical reaction is summarized as follows: n+25131Sn + 102Mo +3 n Find the energy released in this process (in MeV), given that MC3SU) 235.0439 u; M(3Sn) 130.9169 u; M(102Mo)-101.9103 u. b. Lise Meitner's work in 1938 predicted that the fission of...
If 23592U released only 1.5 neutrons per fission on average (instead of 2.5), would a chain reaction be possible? If so, how would the chain reaction be different than if 3 neutrons were released per fission?
