INCAS: an analytical model to describe displacement cascades

RPV-1: A Virtual Test Reactor to simulate irradiation effects in light water reactor pressure vessel steels

“…[13,14]). This section only reminds the main elements which are useful to understand how the simulations are carried out with RPV-1.…”

“…This article is the second of a series aimed at presenting the codes and models used to build RPV-1 [10,11]. Its objective is to describe the structure of the tool and to show its limits and potentialities.…”

“…A comprehensive comparison between results of simulations carried out with RPV-1 and results of experimental programs will be published in a companion paper [12].…”

Modeling Microstructure and Irradiation Effects

“…Theoretical justification for this behavior was provided in Reference 16, which shows that for high PKA energies, where the BCA holds, the mean free path between two high energy collisions (which is proportional to the inverse cross section) is large compared to the cascade extension. To obtain a finite number of low energy PKAs, i.e., PKAs that can be simulated using MD, one can use, for instance, INCAS, [16] which is based on an analytical model of binary collisions. This code predicts the number of (sub)cascades produced, as well as the energy deposited in each subcascade by the PKAs.…”

Displacement damage and transmutations in metals under neutron and proton irradiation

“…Several approaches were developed for assessment of the number of subcascades. Their detailed discussion is outside of the scope of the present paper and can be found elsewhere [27][28][29][30].…”
