[en] Particle accelerators are an important tool for new discoveries and understanding in different principles of all branches of science and engineering. As the science is progressing, new types of techniques are discovered and journey is still going on for new innovative techniques for acceleration, mainly in achieving accelerators for high energies, high currents and so on and uses of these machines in industrial application and nuclear energy generation and waste incineration. As accelerators increase in size and complexity, demands upon their control systems increase correspondingly. Machine complexity is reflected in complexity of control system hardware and software. Same time imposing easy access and operation of the machine with higher degree of reliability and reconfigurability. Model-based procedures and fast feedback based upon even faster beam instrumentation are often required. Managing machine protection systems with hundreds or thousands of inputs is another significant challenge. Increased use of commodity hardware and software introduces new issues of security and control. (author)

[en] Highlights: • Effect of mixed-use neighborhood scenarios on WtE-CHP plant performance is studied. • Various mixed-use neighborhood design parameters are correlated with WtE-CHP. • Feasibility of single and two stage WtE-CHP plants is examined. • Comparison of energy demand and WtE generation presented for various scenarios. • Useful method for optimal selection of WtE-CHP plant for mixed-use neighborhoods. -- Abstract: In this work, the influence of residential and commercial buildings on the performance of waste-to-energy (WtE) combined heat and power (CHP) plant, within a mixed-use neighborhood is quantified. The waste incinerator-based single and double stage CHP plants considered in study are modeled and simulated in Matlab-Simulink. The performance of WtE-CHP plant is evaluated based on hourly electricity and heat generations, heat extraction temperatures, and GHG emissions. The key results indicate that the use of single or double stage CHP plant is decided by various types commercial buildings, commercial land fraction, and commercial land to total area ratio. Considering a commercial land to total land area fraction of 0.25, two stage WtE-CHP plant can be used irrespective to varying proportions of residential buildings types and their unit densities. The heat extraction temperatures of 100–112 °C can be yielded for two stage CHP, whereas, for single stage CHP it lies between 170 and 180 °C. The GHG emissions for WtE-CHP plants decreases with the increase in proportions of offices, single detached houses, and townhouses. However, it increases with the increase fraction of retails and apartments. The energy generation to consumption fraction lies between 17 and 57% for conventional neighborhoods, whereas, for the high-performance neighborhoods it varies between 22 and 65%.

[en] This news is based on the following article: Negri E., Bravi F., Catalani S., et al. Health effects of living near an incinerator: A systematic review of epidemiological studies, with focus on last generation plants Journal of Environmental Research 2020; 184: 109305. Doi: 10.1016/j.envres.2020.109305. Systematic reviews examining the health effects of pollutant emissions from waste incinerators have not yet taken into account their technological developments and huge improvements. This new study makes up for this limitation by analysing the existing data in depth and by classifying the installations into three categories, according to the year they were put into service and legal standards then in effect. It includes suggestions for better-designed and more useful studies for monitoring third-generation plants. (author)

[en] Recursive operability analysis (ROA) is a powerful hazard evaluation method that is particularly suitable for the safety analysis of plants with multiple protection levels activated by the same process variable. The propagation of deviations of the variable along the process lines can be readily determined with this method, and hence the correct sequence in which the protection means must intervene can be appropriately followed. This paper illustrates the versatility of a ROA through its application to a 900 kg/h liquid chlorinated waste furnace. The following process variable deviations were assessed: primary air flow rate, flow rate and lower calorific power of the treated wastes and furnace temperature. It has been shown that the analysis requires a precise determination of how the variables evolve, especially when they are correlated, as is the case with the temperature and oxygen concentration. The ways in which deviations can develop in quantitative terms and the correct sequence in which the protection means must intervene are deduced from a correct study of the process thermodynamics

[en] The radioactive waste incinerator which processes low level waste at the Ontario Power Generation Western Waste Management Facility has been in operation since the year 2002. The purpose of the incinerator is to safely process both solid and liquid low level waste generated by station activities. The majority of waste incinerated consists of paper, wood, plastic, rubber, cotton, and hydraulic oil. The incinerator has undergone a recent modification in the year 2015. This modification was in response to an overheating event in the underfire air duct which resulted in suspension of solid waste incineration. Underfire air duct plugging is a common challenge to many incinerators worldwide. Underfire air duct plugging leads to a reduction in combustion efficiency, additional maintenance burdens, and processing downtime. Thermal damage due to overheating can also occur if flammable material flows through the underfire air duct and burns. The modification was completed safely and successfully by OPG in conjunction with industry partners. The modification has resulted in the return to solid waste incineration as well as improved sustainable performance. The incinerator has now evolved from a controlled air design consisting of both underfire and overfire air to a controlled air design consisting of only overfire air. The paper will address lessons learned during the modification. The paper will also explore key differences between the operation of the original incinerator design and the new design. (author)

[en] Highlights: • Assessment of infectious waste management in Bangkok, in particular incineration. • Integration of social network and stakeholder analysis assessment methods. • Assessment of stakeholder characteristics, role, interaction and communication. • Interviewees self-evaluate their own characteristics and the system. • Non-technical aspects are important for system acceptability, and sustainability. - Abstract: Assessing the strengths and weaknesses of a solid waste management scheme requires an accurate analysis and integration of several determining features. In addition to the technical aspects, any such system shows a complex interaction of actors with varying stakes, decision-making power and influence, as well as a favourable or disabling environment. When capitalizing on the knowledge and experience from a specific case, it is also crucial that experts do not “forget” or underestimate the importance of such social determinants and that they are familiar with the methods and tools to assess them. Social network analysis (SNA) and stakeholder analysis (SA) methods can be successfully applied to better understand actors’ role and actions, analyse driving forces and existing coordination among stakeholders, as well as identify bottlenecks in communication which affect daily operations or strategic planning for the future way forward. SNA and SA, appropriately adjusted for a certain system, can provide a useful integration to methods by assessing other aspects to ensure a comprehensive picture of the situation. This paper describes how to integrate SNA and SA in order to survey a solid waste management system. This paper presents the results of an analysis of On-Nuch infectious waste incinerator in Bangkok, Thailand. Stakeholders were interviewed and asked to prioritize characteristics and relationships which they consider particularly important for system development and success of the scheme. In such a way, a large quantity of information about organization, communication between stakeholders and their perception about operation, environmental and health impact, and potential alternatives for the system was collected in a systematic way. The survey results suggest that stakeholders are generally satisfied with the system operation, though communication should be improved. Moreover, stakeholders should be strategically more involved in system development planning, according to their characteristics, to prevent negative reactions

[en] The recovery of waste heat is increasingly promoted as an instrument for climate change mitigation and energy transition. However, when such a flow is distributed by a heat network, the stakeholders in charge of the network operation do not have control over the flow production. This article aims at understanding the consequences of this lack of control on the construction and running of a network through the analysis of two French case studies in Dunkirk and the Val d'Europe. It shows that the temporal evolution of the heat flow and the projections that the actors make of it lead the decisions taken regarding the network. Hence, the produced flow is put at the center of the network evolution rational and the infrastructure is built accordingly to distribute it. In that sense, the process is inverted from the classic rational of the construction of urban networks. (author)
