Question:

Explain how radiation damage in a steel pressure vessel differs when caused by neutrons and gamma rays, respectively.


Answers

Gama rays cause damage but very few atomic displacements. The damages can include production of lattice defecta in that do not undergo , formation of gas bubble, potential for enhanced leaching. It can also effect the density and chemical durability.

Neutron radiation significantly increases the yield and tensile strength and decreasing the ductility. Also there is an increase in hardness and thereby cause atructural damage to the crystal lattice.
