•Introduction

•Radiation effects on solids (Olander text)

1.Basics of Radiation Damage (Chap. 17)

Collision dynamics; displacements; cross sections; dose(dpa); computer simulation of radiation damage due to neutrons.

2. Ion interactions with solids –

The TRIM code; analysis and demonstration

3. Point defect characteristics(Chaps 6, 7, Sects.- 13.3-13.4)- equilibrium concentrations of vacancies and interstitials; diffusion of point defects; point defect reactions

4. Extended Defects in Solids(Chap. 8, Sect. 13.2) - bubbles and voids; dislocations

5. Interaction of point defects and extended defects (Sect. 13.5); diffusion of point defects to cavities and dislocations; interstitial bias of dislocations; point defect balances

Applications to Fission Reactors

6. Void Swelling (Chap. 19); nucleation and growth of voids; effect of gas pressure on swelling 7. Irradiation and Thermal Creep (Sect. 19.7) - swelling-driven creep; SIPA creep

8. Irradiation growth

9. Structural Analysis under Irradiation (Chap. 21)- effects of temperature, swelling and creep

Applications to Fusion Reactors (Dolan test)

10. Fusion Materials (Chap. 24)

11. Vaporization of Plasma-Facing Components (p. 705)

12. Sputtering (pp. 700 - 703)

13. Hydrogen and Tritium Behavior (pp. 696 - 699, 806 - 810)

14. Blistering (pp. 706 - 708)
