Recent advances in the nuclear power generation field have pointed out the need for ferritic steels which will maintain properties at high operating temperatures for extended periods of time. Present designs for the Clinch River Breeder Reactor Project (CRBRP) specify the use of low carbon 2 1/4 Cr - 1 Mo steel for the Steam Generation systems. Many materials development programs have concluded the acceptability of this material; however, little industrial data are available on the mechanical properties of full size production components. This paper evaluates two heats of low carbon 2 1/4 Cr-1 Mo steel subjected to various heat treatments.

Low Carbon Energy

The world is at a pivotal crossroad in energy choices. There is a strong sense that our use of energy must be more sustainable. Moreover, many also broadly agree that a way must be found to rely increasingly on lower carbon energy sources. However, no single or clear solution exists on the means to carry out such a shift at either a national or international level. Traditional energy planning (when done) has revolved around limited cost projections that often fail to take longer term evidence and interactions of a wider set of factors into account. The good news is that evidence does exist on such change in case studies of different nations shifting toward low-carbon energy approaches. In fact, such shifts can occur quite quickly at times, alongside industrial and societal advance, innovation, and policy learning. These types of insights will be important for informing energy debates and decision-making going forward. Low Carbon Energy Transitions: Turning Points in National Policy and Innovation takes an in-depth look at four energy transitions that have occurred since the global oil crisis of 1973: Brazilian biofuels, Danish wind power, French nuclear power, and Icelandic geothermal energy. With these cases, Dr. Araújo argues that significant nationwide shifts to low-carbon energy can occur in under fifteen years, and that technological complexity is not necessarily a major impediment to such shifts. Dr. Araújo draws on more than five years of research, and interviews with over 120 different scientists, government workers, academics, and members of civil society in completing this study. Low Carbon Energy Transitions is written for for professionals in energy, the environment and policy as well as for students and citizens who are interested in critical decisions about energy sustainability. Technology briefings are provided for each of the major technologies in this book, so that scientific and non-scientific readers can engage in more even discussions about the choices that are involved.

Clean energy transition is one of major transformation processes in the EU. There are different approaches among EU countries to decarbonization of their energy systems. The article deals with clean energy transition in France with the emphasis on power generation. While this transformation process is in line with similar developments in the EU, the Franch case has its distinct nature due to nuclear power domination in electricity production there. It represents a challenge for the current model as the transition is linked to a sharp drop of nuclear share in the power mix. It is important to understand the trajectory of further clean energy transition in France and its ultimate model. The article reviews the historical roots of the current model (which stems from Messmer plan of the 1970-es) and its development over years, as well as assesses its drawbacks and merits in order to outline possible future prospects. The conclusion is that the desired reduction of nuclear energy is linked not solely to greening process but has a complex of reasons, the ageing of nuclear reactors being one of them. Nuclear power remains an important low-carbon technology allowing France to achieve carbon neutrality by 2050. A desired future energy model in France can be understood based on the analysis of new legislation and government action plans. The targeted model is expected to balance of nuclear and green energy in the generation mix in 50% to 40% proportion by 2035, with the rest left to gas power generation. Being pragmatic, French government aims at partial nuclear reactors shut down provided that this will not lead to the rise of GHG emissions, energy market distortions, or electricity price hikes. The balanced French model is believed to be a softer and socially comfortable option of low-carbon model.
