Small Modular Reactors: Licensing constraints and the way forward
No full textSMR (Small Modular Reactor) is an acronym for a group of nuclear power plant designs receiving an increasing deal of attention from the industry and policy makers. A large number of SMRs need to be built in the same site and across the word to compensate diseconomies of scale and be cost competitive with large reactors and other base-load technologies. A major barrier is the licensing process, historically developed for large reactors, preventing the simply deployment of several identical units in different countries. This paper, discussing Ramana, Hopkins and Glaser [1], enlarges the view to all the SMRrelated implications on the licensing process, presenting their legislative implications and market effects.

Special Purpose Entities in Megaprojects: Empty Boxes or Real Companies?
No full textMegaprojects involve organizations called "Special Purpose Entities" (SPEs) also known as "special purpose vehicles." Despite their relevance, particularly for governance, SPEs are under-investigated. In the project management literature, there is neither a widely accepted definition of SPEs nor a clear understanding of what it does. This article presents an extensive literature review, which considers three domains: legal, financial, and project management. Four outcomes are presented: the definition of SPE, the typology of existing SPEs, comparisons of existing SPEs, and descriptions of SPE uses in megaprojects

Characterising Nuclear Decommissioning Projects: an Investigation of the Project Characteristics that Affect the Project Performance
Full text linkHistorically, project management research on infrastructure has mostly focused on its planning, design and construction. However, globally, more and more infrastructure, such as nuclear power plants, bridges, dams or oil rigs, are reaching their end-of-life and will soon need to be decommissioned. Decommissioning projects are long, complex and range from small projects to multi-billion megaprojects. Their costs keep increasing, while there is a limited understanding of why this happens. Nuclear Decommissioning Projects and Programmes (NDPs) are the unit of analysis of this article, due to the relevance of this sector and the number of public information available. The aim is to identify the NDP characteristics that mostly affect the NDP performance in terms of cost and time. Findings from the application of content analysis on the information collected through 35 interviews with senior practitioners highlight the importance of several NDP characteristics, including the need to have detailed knowledge of the site conditions, a good relationship with the regulatory authorities, the availability of storage facilities and stable funding
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
