WebFeb 1, 2024 · Nuclear reactor fuel pellets in operation may be damaged in various ways; in particular, crack nucleation. We consider a problem for the case of a heat-releasing fuel pellet with cladding: as the heat release intensity increases, zones of heightened stress are formed in the nuclear fuel pellet. WebMay 21, 2024 · Oterkus and Madenci used the BB PD to investigate cracking of UO 2 nuclear fuel pellet during the operation of a power plant. Wang et al. studied the thermal crack in rocks using BB PD. Hu et al. performed the thermomechanical analysis with ordinary state-based (OSB) PD. The elastic dilatation can be evaluated by removing the thermal …
