Plant efficiency: a sensitivity analysis of the capacity factor for fusion power plants with high recirculated power [PDF]
Nuclear Fusion Vol. 61, 046032 (2021), 2021 The plant efficiency of a nuclear fusion power plant is considered. During nominal operation, the plant efficiency is determined by the thermodynamic efficiency and the recirculated power fraction. However, on average the reactor operates below the nominal power, even when the long shutdown periods for large maintenance are left outside the averaging ...

Causes of Design Change Depending on Power Project-Types in Ghana
Energies, 2021 Design change is a common but significant problem in construction projects. Issues of delay, cost overruns, claims, and disputes in projects occur as a result. However, design change studies in the power-project area are less often discussed. As a result,
