Flashcards: Nuclear Energy Principles and Reactions — 12 cartões

Mass-energy equivalence — formula?

E=mc^2

Nuclear binding — role?

Keeps nucleons together in nucleus.

Mass defect — definition?

Difference between nucleon sum and nucleus mass.

Deuterium nucleus — composition?

One proton and one neutron.

Alpha decay — energy release?

Energy from mass change via E=Δm c^2.

Nuclear fusion — process?

Light nuclei combine into heavier nucleus.

Chain reaction — key factor?

Number of neutrons triggering further fissions.

Mass defect — calculation?

Δm = m_particles - m_nucleus.

Deuterium binding energy — calculation?

Convert Δm into energy using E=Δm c^2.

Fission reaction — example?

U-235 absorbs neutron, splits into smaller nuclei.

Fusion reaction — example?

H-2 + H-3 → He-4 + neutron.

Chain reaction — control?

Regulated by neutron moderation and multiplication factor.
