The objective of this work is to develop an adequate procedure to determine mechanical properties of nuclear reactor components by means of small specimen test technique. Atomic reactor power plant is a huge structure that the safety factor due to its special function is momentous. The irradiation can change the mechanical properties of the steel used in nuclear power plant structure. The radioactive effect on the vessel of nuclear power reactor causes radiation damage by altering the material properties of nuclear pressure vessel. The effects of the irradiation are mainly important on the...

The main objective of this book is to develop a method to define the optimum cooling rate for cooling continuously as-cast steel on industrial level. An FEM algorithm is introduced to simulate the cooling of as-cast steel from any temperature below the solidification temperature and to predict the generation of the stress concentration regions due to the thermodynamic strains during cooling a steel specimen with different cooling rates. The algorithm is capable of being customized to simulate the thermodynamic behavior of as-cast steel microstructure with any chemical composition and any...
