Nuclear Energy and the Low Carbon Transition
This PhD thesis examines the role of nuclear energy in the transition to a low carbon economy in the United Kingdom. Theories of sustainable development, including ecological modernisation, are used to frame its findings and emerging geographies of nuclear new build are explored. Analysis of policy …

The effect of elevated temperatures on the wear of medium-chromium steel in carbon dioxide
… lifetimes of components subject to vibration in nuclear power stations. High speed unidirectional sliding experiments were carried out at room temperature in order to characterise the general wear behaviour of the steel. Slow speed unidirectional sliding tests were run in both atmospheres so that …

Nonlinear estimation for condition monitoring of advanced gas-cooled nuclear reactor cores
As the Advanced Gas-cooled Reactor (AGR) nuclear power stations are ageing, the nuclear core composed by graphite bricks can distort. The direct measurement of the core condition is costly and time-consuming, hence, alternative methods have been developed to provide the necessary information about …
