Some aspects of the VVER-440 reactor plant life re-extension: a case study of the Novovoronezh NPP Unit 4 [PDF]

Nuclear Energy and Technology, 2019
The re-modernization of Unit 4 at the Novovoronezh NPP (Novovoronezh-4) made it possible to take a new approach to the problem of extending the VVER-440 reactor plant life and operation. The authors analyze the existing problems of the VVER-440/179 power

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 ...

Influence of operating time on the corrosion in single-phase and two-phase media [PDF]

Nuclear Energy and Technology, 2021
Modern foreign computer codes predict a linear growth in the pipeline wall thinning with time due to the process of flow-accelerated corrosion (FAC), i.e. erosion-corrosion wear (ECW).

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,

Using Machine Learning to Predict the Fuel Peak Cladding Temperature for a Large Break Loss of Coolant Accident

Frontiers in Energy Research, 2021
In this paper the use of machine learning (ML) is explored as an efficient tool for uncertainty quantification. A machine learning algorithm is developed to predict the peak cladding temperature (PCT) under the conditions of a large break loss of coolant
