China prioritizes clean energy for power generation in response to climate change and air pollution. By the end of 2021, the installed capacity of wind power has reached 328.48 GW, accounting for 13.8% of China's total installed capacity of 2376.92 GW. However, wind power is inherently unstable and its output depends on resources, which poses challenges for the national grid. Wind curtailment is often encountered when electricity production is plentiful. The main objective of this work is to develop a clean energy generation system for on-demand power supply to improve the utilization of wind resources. The LBE reactor is also a clean energy source with flexible power regulation that helps mitigate the impact of wind variability. Therefore, a hybrid wind-nuclear power system (HWNPS) is proposed. This paper demonstrates the technical feasibility of the LBE reactor and conducts a preliminary analysis of the economics of the HWNPS. The additional cost of HWNPS due to power regulation is about $ 9.04/MWh, which has potential for research and development. [ABSTRACT FROM AUTHOR]

China's record in reducing poverty over the last three decades has been impressive, yet few studies have examined the incidence of poverty among older people despite the rapid ageing of the population. This article uses a unique national data set to examine patterns of poverty, deprivation and exclusion among the urban aged population (60 years and over) in 2000. The results point to the importance of poverty as an issue for older people, particularly for women and those who live alone. A number of indicators of hardship are developed in four areas – economic insecurity, housing, health, and social isolation – and the incidence of these is examined, separately and in combination, by living arrangement and gender. Women are shown to experience greater levels of hardship and isolation than men, and to be more likely to experience multiple deprivation across two or more areas. Finally, the overlap between poverty and hardship is examined as a way of validating the poverty estimates and giving them greater credibility. The results indicate that there are strong overlaps, although these differ across the different dimensions of hardship. Access to pension income and concern over the cost of necessary visits to see a doctor emerge as strong predictors of poverty and point to areas where policy change is needed. [ABSTRACT FROM AUTHOR]
