Modeling fast neutron irradiation damage accumulation in tungsten

Due to its advantageous physical properties, tungsten (W) is being considered as a candidate structural material in fusion applications. In this paper, we perform stochastic cluster dynamics calculations of irradiation damage accumulation in pure W under fast neutron spectra in up to doses of 1.5 dpa in the 400∼600◦C interval. Our calculations suggest that He bubbles and dislocation loops accum...

Modeling Irradiation Damage Accumulation in Crystals

Bombardment of crystalline solids by energetic particles produces lattice defects, the accumulation of which is the origin of the macroscopic effects of irradiation damage. In an all-inclusive theory, the defects produced fall into two categories: (1) atomic displacements creating freely migrating vacancies and interstitials and their clusters, both mobile and immobile; and (2) transmutations c...

Making a novel method to obtain the required irradiation time in fast neutron radiation therapy of liver tissue

During radiotherapy by any radiation, it is always essential to stop absorbing the excess dose by a tissue. To better treat cancerous tissues and to make more precise irradiation for a cancerous tumor, there needs the accurate irradiation time to be estimated. First, the constituent materials of any of the existing organs in abdominal tissue are extracted and defined in the MCNPX code. Then, ev...
