load shifting of Nuclear Power plants using cryogenic energy storage technology
Applied Energy, 2014Co-Authors: Yongliang Li, Dacheng Li, Shuhao Wang, Yulong Ding, Xiang WangAbstract:To balance the demand and supply at off-peak hours, Nuclear Power plants often have to be down-regulated particularly when the installations exceed the base load requirements. Part-load operations not only increase the electricity cost but also impose a detrimental effect on the safety and life-time of the Nuclear Power plants. We propose a novel solution by integrating Nuclear Power Generation with cryogenic energy storage (CES) technology to achieve an effective time shift of the electrical Power output. CES stores excess electricity in the form of cryogen (liquid air/nitrogen) through an air liquefaction process at off-peak hours and recover the stored Power by expanding the cryogen at peak hours. The combination of Nuclear Power Generation and the CES technologies provides an efficient way to use thermal energy of Nuclear Power plants in the Power extraction process, delivering around three times the rated electrical Power of the Nuclear Power plant at peak hours, thus effectively shaving the peak. Simulations are carried out on the proposed process, which show that the round trip efficiency of the CES is higher than 70% due to the elevated topping temperature in the superheating process and thermal efficiency is also substantially increased.

activist protest spillovers into the regulatory domain theory and evidence from the u s Nuclear Power Generation industry
Research Papers in Economics, 2021Co-Authors: Adam Fremeth, Guy L F Holburn, Alessandro PiazzaAbstract:We examine how social activism—in the form of public protests against contentious business practices—can spill over into the regulatory domain, extending beyond activists’ articulated goals to affect firms’ regulatory outcomes in areas that are not directly targeted. We argue that firms are likely to experience broader regulatory repercussions after activist protests because public contention invites greater scrutiny of firm behavior by industry regulators, increasing the likelihood that instances of organizational non-compliance will be discovered. Protests can also cause regulators to evaluate targeted firms more negatively in regulatory assessments, especially firms with less favorable pre-existing reputations or stakeholder relations, and to tighten regulations on non-targeted issues that signal their commitment to safeguarding the public interest. We further contend that the political context within which regulatory agencies operate shapes the extent of protest spillovers: when political institutions are aligned with activist goals, and when regulators are ideologically sympathetic too, protests have a more pronounced negative impact on firms’ regulatory outcomes in non-targeted domains. We find robust support for our predictions in a statistical analysis of the impact of anti-Nuclear protests – which sought to block Nuclear Power plant development by electric utilities – on utilities’ subsequent regulated financial rates of return on their assets. Our analysis contributes new insights to research on the indirect consequences for targeted organizations of social activism.

categorical stigma and firm disengagement Nuclear Power Generation in the united states 1970 2000
Organization Science, 2015Co-Authors: Alessandro Piazza, Fabrizio PerrettiAbstract:How do organizations react to stakeholder disapproval of a category to which they belong? In this paper, we draw on the categorization, stigma, and identity literatures in building a theory to predict whether firms that are involved in stigmatized activities will choose to reduce or terminate their involvement in them, as opposed to resorting to less drastic measures such as defensive practice adoption or impression management techniques. Conceptualizing groups of organizations involved in such contentious practices as stigmatized categories in the eyes of an audience, we argue that organizational responses rest on three elements: 1 the intensity of stigma targeting the category, 2 the media exposure of the category, and 3 the extent to which an organization is a member of the category. A quantitative study of proposed new Nuclear reactor units in the United States between 1970 and 2000, in the face of mounting opposition to atomic Power, provides empirical support for our claims.

categorical stigma and firm behavior Nuclear Power Generation in the u s 1970 2000
Academy of Management Proceedings, 2014Co-Authors: Alessandro Piazza, Fabrizio PerrettiAbstract:In this paper, we draw on the categorization, stigma, and identity literatures in building a theory to predict firm behavior in response to the stigmatization of a category to which the organization belongs. Specifically, we argue that firm response depends on two elements: (1) the extent to which an organization is a member of the stigmatized category; and (2) the intensity of stigma, which we conceptualize as the amount of disapproval expressed in the media towards the category as a whole. Organizations that are prominent members of a stigmatized category—we contend—will be comparatively more prone to perceive such category as an integral part of their identity, and as such they will be more reluctant to abandon it. Moreover, the stronger the stigma effect that a category experiences, the higher the likelihood of defection; this effect will be especially prominent under conditions of low media exposure, due to a contrast effect. A quantitative study of proposed new Nuclear reactor units in the United St...

cryogenic energy storage and its integration with Nuclear Power Generation for load shift
2019Co-Authors: Qinghua Yu, Yongliang Li, Tongtong Zhang, Lige Tong, Xinjing Zhang, Xiaodong Peng, Lin Cong, Xiaosong Zhang, Li Wang, Haisheng ChenAbstract:Abstract This chapter concerns mainly the integration of cryogenic energy storage (CES) with Nuclear Power plant (NPP) for load shift. It starts with an introduction to the CES technology including basic principle, development history, process diagram, performance evaluation, and applications. Data obtained during an operation of the world first CES pilot plant (350 kW/2.5 MWh) are presented to illustrate the potential use of the CES in electric Power grids. This is followed by the comparison of the CES technology with two other major large-scale energy storage technologies, pumped hydro and compressed air energy storage, demonstrating clear advantages of the CES technology in terms of energy density, no geographic and geologic constraints, and flexibility. The integration of the CES technology with NPPs is then discussed. Such an integrated system could be operated in three modes of electric energy storage, electric energy release, and conventional operation, offering significant cost-effective load-shift capabilities and flexibility. Thermodynamic analyses suggest that the integrated system could deliver 2.7 times the NPP rated Power and achieve a round-trip efficiency of the CES at ~ 71%.
