Form of energy released from nucleus. Produced in two ways: Fusion and Fission

Fuel that is used in nuclear reactor to sustain a nuclear chain reaction. Source of energy by nuclear reactors. Energy released through nuclear fission.

Substance that possess unique properties releated to their atomic structure. Used in nuclear technology and power generation.

Two groups of Nuclear Materials

Capable of undergoing nuclear fission

Most abundant isotope of uranium.

Can be converted to uranium 233.

Slow down fast neutron

Reflect neutron back in core

Absorb Neutrons & Control Nuclear Reaction

Transfer heat away from core

Sustain a controlled nuclear fission reaction in nuclear reactors.

Common types of Nuclear Fuel Materials

Industrial process to produce electricity from radioactive element. Starts with mining uranium and ends with disposal of fuel.

Versatile nuclear fuel pre-cursor used in blanket fuel applications due to its resistance in high temperatures.

4 Processing stages of UO2

When uranium is refined to a concentrated product.

A process wherein uranium is converted to a form for fuel fabrication/enrichment.

Two methods of uranium enrichment process.

Forcing gaseous UP6 through semi-permeable membranes to produce slight seperation.

Involves rotating cylinders in series & parallel for motions.

Fabricated fuel assemblies are loaded into nuclear reactor for irridation of nuclear fuels.

Initiated by bombarding a fissile atom. Atom splits into two smaller atoms.

Strategy by nuclear power plants for optimum safety, involving multiple safety systems. Includes high quality design & construction

Core aspects of strategy

Three fundamental safety functions
