Integrating water reclamation and electrolysis processes for green hydrogen production: an economic evaluation
No full textIn this work, the production of green hydrogen using an electrolyser fed with the water produced in a water reclamation process was economically evaluated. The water reclamation process was considered to be implemented in a municipal wastewater treatment plant (WWTP) and consisted of an ultrafiltration and multiple-pass reverse osmosis system. The results illustrated that specific water consumption and water production costs featured a minimal impact on the levelized cost of hydrogen (LCOH). Specifically, the LCOH was around 3 €/kgH2 regardless of the water reclamation scenario evaluated. These results point out that the levelized cost of producing hydrogen using water electrolysis would not experience noticeable variations after implementing an advanced water reclamation scheme in a WWTP. Overall, this study highlights the potential of integrating water reclamation and electrolysis processes to improve the sustainability and resource recovery of future WWTPs.The authors acknowledge the Spanish Agency of Research (AEI) through the project development of upcycling approaches in the agri-food and process industries to promote on-site and sustainable chemicals production (UPCYCLING) (PID2023-147160OB-C21) and Catalan Government for the project 2021-SGR-GRC-00596.Postprint (published version
Analysis of the neutronic performance and reactivity feedback coefficients of lead fast reactors
No full textThe growing global demand for clean and sustainable energy has sparked significant interest in advanced nuclear technologies, particularly those encompassed within the Generation IV nuclear energy systems. Among these, LFRs are gaining attention across Europe, and especially in Belgium. Furthermore, the need to reduce costs and make nuclear energy more attractive and flexible has promoted the development of SMRs concepts. LFRs offer notable advantages, including inherent safety features, high neutron economy, and the potential for improved fuel utilization. However, challenges persist in optimizing core design, material performance, and economic feasibility. The SMR-LFR project at SCK CEN seeks to explore the potential of integrating SMR principles with LFR technology, focusing on the development of a small modular lead fast reactor demonstrator. This thesis contributes to the SMR-LFR project by investigating the core design and performance characteristics of three different SMR-LFR concepts. Using the Serpent2 Monte Carlo neutron transport code, the study evaluates key neutronic and safety parameters, such as Doppler reactivity feedback and delayed neutron fraction, under static criticality conditions. The analysis examines how fuel enrichment, geometric configurations, and other design variables impact reactor performance, guiding optimization toward safe, efficient, and economically viable solutions. Additionally, the thesis validates the methodology by developing a benchmark for the SEFOR and comparing the Doppler constants obtained through simulations with experimental data. Next, a X-sec sensitivity analysis is conducted on the SEFOR benchmark and the most promising SMR-LFR designs, to asses the viability of using SEFOR as a representative benchmark for the validation of the nuclear data and computer code predictive capabilities for the Doppler constant of LFRs. The findings of this research provide valuable insights into SMR-LFR core design, the impact of design parameters on reactor performance, and the validation of computational methods, supporting the advancement of small modular LFR technology and its future deployment in the nuclear energy sector.Outgoin
Preparación del Mundial de Mini-Z. PNWC París 2024
No full textA lo largo de este documento, se realiza el estudio de aspectos necesarios para poder asistir a la competición más importante a nivel mundial de coches de radiocontrol en la categoría Mini-Z. El objetivo que me ha llevado a realizar este proyecto es la ilusión y el deseo de poder comprender de manera más profunda el comportamiento del coche a partir de la dinámica y la electrónica que lo componen. Para llevar a cabo el proyecto, en la parte teórica, ha sido necesario realizar búsqueda por internet, pero la mayor parte de la información se ha obtenido mediante reuniones con personas relacionadas a la competición, como son por un lado un ingeniero mecánico y, por otro, el responsable de comunicación y atención al cliente de la tienda más importante de Mini-Z a nivel nacional, Technical Racing Products. En la parte práctica, se han realizado entrenamientos en diferentes circuitos para poder comprender y aplicar de la mejor manera todos los conceptos adquiridos previamente con la teoría. Para ello, fue necesario un tiempo de adaptación por mi parte, ya que hacía varios años que no tenía ningún tipo de contacto con el radiocontrol. Al final del primer entreno, tenía algunas sensaciones encontradas y para los días posteriores ya se pudo empezar a hacer cambios en los ajustes del coche. Pasados unos meses, en el Campeonato Mundial de Mini-Z, llegó el momento de poner sobre la mesa lo trabajado. Las primeras impresiones sobre la pista no fueron malas, pero dejaron ver que faltó tiempo de preparación, comparado a ciertos rivales, en cuanto a material se refiere, pero referente al contexto que me llevó a proponer este proyecto quedo muy satisfecho, tanto con la idea como por el trabajo realizad
Terrestrial very-long-baseline atom interferometry: summary of the second workshop
No full textThis summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024 (Second Terrestrial Very-Long-Baseline Atom Interferometry Workshop, Imperial College, April 2024), building on the initial discussions during the inaugural workshop held at CERN in March 2023 (First Terrestrial Very-Long-Baseline Atom Interferometry Workshop, CERN, March 2023). Like the summary of the first workshop (Abend et al. in AVS Quantum Sci. 6:024701, 2024), this document records a critical milestone for the international atom interferometry community. It documents our concerted efforts to evaluate progress, address emerging challenges, and refine strategic directions for future large-scale atom interferometry projects. Our commitment to collaboration is manifested by the integration of diverse expertise and the coordination of international resources, all aimed at advancing the frontiers of atom interferometry physics and technology, as set out in a Memorandum of Understanding signed by over 50 institutions (Memorandum of Understanding for the Terrestrial Very Long Baseline Atom Interferometer Study).The workshop was partially funded by contributions from the Long Range Broad Agency Announcement (BAA) for the Navy and Marine Corps Science and Technology programme, Hannover Leibniz University, and the Physics Department at Imperial College London.Article signat per 322 autors/es: Philippos Balamatsias, Antun Balaž, Hannah Banks, Rachel L.

Computation and Conversation
No full textEvery computational process seems to involve two or more entities that are engaged in a conversation with each other. Communication complexity is the study of the complexity of such conversations. In this talk, I will give a broad overview of this connection between computation and conversations, including some nice consequences for computational models like Turing machines and data structures. I will describe some of the big open questions in the area, which are clean mathematical questions in their own right. No background will be assumed
