Tungsten is one of the candidates for the diverter armor tiles due to the low solubility for hydrogen, excellent thermal properties and low sputtering properties, etc. In the present work, we investigate structure of hydrogen atoms in tungsten in first principle method by using Vienna ab initio simulation package (VASP). In the irradiation atmosphere, many vacancies are introduced in the plasma facing materials. So, we investigate preferable site for hydrogen atom in bulk tungsten and structure of hydrogen-vacancy complexes in tungsten, as well.
