Time-Series Forecasting of a Typical PWR Undergoing Large Break LOCA

Science and Technology of Nuclear Installations
In this work, a machine learning (ML) metamodel is developed for the time-series forecasting of a typical nuclear power plant response undergoing a loss of coolant accident (LOCA). The plant model of choice is based on the APR1400 nuclear reactor.

Assessing the spatio-temporal variability of vegetation productivity in Africa: quantifying the relative roles of climate variability and human activities

International Journal of Digital Earth, 2017
Quantitative attribution at the individual pixel level of the relative contributions of climate variability and human activities to vegetation productivity dynamics across Africa is generally lacking.

Classification of Nuclear NPP Reactors

NTU "KhPI" Bulletin: Power and heat engineering processes and equipment
The article deals with the classification of NPP nuclear reactors. A nuclear reactor is a device in which a chain reaction of nuclear fission of heavy elements uranium, plutonium, and thorium takes place, which controls and maintains itself. The possibility of such a reaction is ensured by the fact that each act of nuclear fission produces two or three

Linking Ecosystem Risk, Health, Services to Ecological Security Assessment in the Yellow River Basin: Spatiotemporal Dynamics and Nonlinear Driving Characteristics

Land Degradation &Development, EarlyView.
ABSTRACT A scientific assessment of ecological security (ES) and its nonlinear mechanism for key driving factors in the Yellow River Basin (YRB) is of great significance for ecological protection and sustainable development. This study proposes an ES assessment framework, which links ecosystem risk (ER), ecosystem health (EH), and ecosystem services ...

Driving Mechanisms of Land Degradation Neutrality at the County Level and Zonal Strategies in the Yellow River's Key Ecological Region (Part II: Post‐Assessment Driver Analysis)

Land Degradation &Development, EarlyView.
ABSTRACT Achieving land degradation neutrality (LDN) is critical for sustainable socio‐ecological development; however, its practical implementation is often hindered by scale mismatches between assessments and administrative units, coupled with an over‐reliance on static drivers.
