Requirement, Characteristics. Choice of Materials which are Moderators as well as Reflectors. Effect of radiation. Solid reflectors.

Why we need Moderators? Nuclear cross sections for effective moderators. Parameters to assess effectiveness - Average logarithmic energy decrement, Macroscopic slowing down power, Moderating Ratio. Characteristics of Moderating materials, Potential Moderators - elements and compounds.

Requirement of coolant, characteristics and different coolant materials, possible design options, corrosion and liquid metal embrittlement.

Requirement of Controlling Fission reactions. Possible methods. Characteristics of control rod materials, properties of some selected popular poison materials.

Requirements and Characteristics of Cladding Materials. Nuclear cross sections for absorption of thermal neutrons for potential cladding materials. Why zirconium and not a specific isotope of Zr? Zr alloys for cladding and their compositions.

Materials used in hot area and their nuclear cross sections, fissile materials, characteristics, advantages and disadvantages of metallic fuels, fissile kernels for Generation IV reactors.

Fissile isotopes of Uranium and Plutonium. Fertile materials. Breeder Reactors

neutron absorption, fission reaction

Discusses fast and thermal neutrons, flux and fluence of neutrons, nuclear cross-sections and fission 27:30 to 27:50: Materials for Poison require sigma of absorption to be LARGE and NOT sigma for Scattering. Please correct this mistake.
