Calculating Free Energy in Nuclear Fuel Reactions

Click For Summary
SUMMARY

The discussion focuses on calculating the free energy released from 1 kg of nuclear fuel, specifically the reaction involving Uranium-235 (235U) and neutrons. The energy release from the reaction is noted as 176 MeV, which is crucial for accurate calculations. Participants discuss the need to balance the nuclear equation and the importance of determining the number of atoms in 1 kg of uranium for precise energy calculations. The conversion of energy from MeV to kilojoules is also highlighted, with 1 mol of 235U equating to 16.5 kJ.

PREREQUISITES
  • Understanding of nuclear reactions, specifically the fission of Uranium-235.
  • Familiarity with energy conversion units, particularly MeV to kJ.
  • Basic knowledge of Avogadro's number for calculating the number of atoms in a given mass.
  • Proficiency in using Einstein's mass-energy equivalence formula, E=mc².
NEXT STEPS
  • Research the process of balancing nuclear equations in fission reactions.
  • Learn how to convert energy units from MeV to kilojoules accurately.
  • Study the implications of neutron production in nuclear reactions.
  • Explore the concept of Avogadro's number and its application in calculating atomic quantities.

Homework Statement


Calculate how much free energy in 1kg of nuclear fuel, assuming the most common reaction at a nuclear plant is 235U + n ---> 139Ba + 86Kr + 11n + 176 mev

Homework Equations


E= mc2 ?
1mol of 235U = 16.5 KJ

The Attempt at a Solution


Do I need to balance the equation? How do I do that?

Can you find how many atoms are in 1 kg of uranium? Is the energy release from a single reaction 176 meV or 176 MeV? It makes a whole lot of difference.
 
nevermind, I found what i was looking for on youtube. Thanks!
