CHP (combined heat and power) retrofit for a large MED-TVC (multiple effect distillation along with thermal vapour compression) desalination plant: H…
2016
Abstract Integrated power plants in “dual purpose” configuration may represent a viable option for energy cost abatement of desalted water produced by MED-TVC (Multiple Effect Distillation along with Thermal Vapour Compression). In this paper an existing large MED-TVC plant with a 36,000 m 3 /day capacity is studied: a plant retrofit is designed, based on a steam power plant with condensation and steam extraction used to drive the steam ejector. As the plant operates in CHP (Combined Heat and Power) mode, the possibility to assess the integrated “CHP + MED-TVC” as high efficiency cogeneration according to Directive 2004/8/EC is discussed. Based on a model developed in Engineering Equation S…
Technological performances upgrading and rehabilitation of building heritage inside the historic centre of Palermo
2021
The recovery of building heritage through the containment of carbon emissions is one of the strategies pursued by the city of Palermo. This design approach becomes more paradigmatic when it’s referred to sensitive and historic buildings or urban areas, having an international interest or involved in participatory projects for the Mediterranean city, well beyond the attention that citizens attest to them. We would analyse the Volta electrical Power Station, inside the harbour area and near the Castello a mare, interested by the overall rehabilitation of Palermo waterfront. This building qualifies itself, through a retrofit hypothesis proposed by the authors of this essay, as a significant ex…
Helios and Aeolus
2012
In summer it’s always hot in the Big Apple, but the summer of 2003 had been especially sweltering. Temperatures had been around 35oC during all the month, with humidity approaching one hundred percent. The higher the temperature, the lower the New Yorkers’ thermostats, up to the point where you needed a sweater at the office, while outside delivery men, mail carriers and peddlers had to suffer the heat, together with the tourists brave enough to venture through the smoldering avenues.
Fuel for commercial politics: the nucleus of early commercial proliferation of atomic energy in three acts
2020
Historical research into the nuclear industry has focussed upon military and commercial aspects of the technology whilst ignoring fuel. This article discusses nuclear fuel, the resource at the centre of the industry and the role superpower politics played in its supply. Starting with the context of superpower competition, we examine the spread of nuclear technology from its beginnings in post-war Britain via West Germany in the 1950s to Finland in the 1960s and 1970s. We demonstrate that each country had varied interests affecting the choice of nuclear fuel for early energy projects; British fuel choices were constrained by its weapons programme and Germany needed legitimacy in the face of …
Analysis of Protected Accidental Transients in the EFIT Reactor With the RELAP5 Thermal-Hydraulic Code
2008
The European Facility for Industrial Transmutation (EFIT) is aimed at demonstrating the feasibility of transmutation process through the Accelerator Driven System (ADS) route on an industrial scale. The conceptual design of this reactor of about 400 MW thermal power is under development in the frame of the European EUROTRANS Integrated Project of the EURATOM Sixth Framework Program (FP6). EFIT is a pool-type reactor cooled by forced circulation of lead in the primary system where the heat is removed by steam generators installed inside the reactor vessel. The reactor power is sustained by a spallation neutron source supplied by a proton beam impinging on a lead target at the core centre. A …
Core and Shell: facciate storiche e nuovi edifici. Il caso dell’ex Chelsea and Fulham Power Station a Londra
2022
The maintenance of the façade(s) is one of the most common solutions – in countries where this intervention is allowed – which can also guarantee the “preservation” of the existing built herit- age, as well as the construction of new “zero land consumption buildings”. The English term used to identify this area of work is Façadism. The paper analyses a perfect example attributable to this area of work that is being implement- ed on the former Chelsea and Fulham Power Station in London. The refurbishment project, in the construction phase, was instructed to Midgard Design Service Ltd (Design Department of the Irish construction company JRL Group Limited) which will transform the entire area …

Invenzione, composizione e tempo nell’architettura di Giuseppe Samonà; Invention, Composition and Time in the Architecture of Giuseppe Samonà
2016
Una riflessione su alcune costanti presenti nell’opera di Giuseppe Samonà deve anticipare un approfondimento dedicato esclusivamente alle centrali termiche realizzate in Sicilia dal 1955 al 1962. Si vogliono inquadrare le ragioni di alcune scelte senza per questo avere la pretesa di raggiungere un’esaustività critica rispetto alle molte questioni offerte dall’ampia produzione teorica e progettuale di Samonà. Se si osserva l’architettura di Samonà, in termini di invenzione e composizione ci si accorge come la cosiddetta “rivoluzione miracolosa”, non è una frattura ma una sorta di aggiornamento nel “già costruito” preso a riferimento. Il procedere di Samonà assoggettando frammenti e il rielab…
Preliminary Thermo-Mechanical Design of the Once Through Steam Generator and Molten Salt Intermediate Heat Exchanger for EU DEMO
2020
The European DEMOnstration power plant (DEMO) is considered to be the nearest-term fusion reactor capable of producing several hundred MWs of net electricity, operating with a closed tritium fuel-cycle (achieving the tritium self-sufficiency), and qualifing technological solutions for a fusion power plant with different breeding blanket (BB) concepts that are under investigation. The BB is a key component for the development of the DEMO plant design and, in particular, of those systems having the responsibility to remove the plasma-generated thermal power and its conversion in the electrical energy. This study deals with the preliminary thermo-mechanical design of the heat exchangers and st…
Il confronto delle idee. Visioni progettuali per un recupero possibile (The comparision of ideas. Design concepts for a possible recovery)
2016
Il saggio dà conto e avanza una sintesi dell'esperienza di ricerca attuata nell'ambito del Dipartimento di Architettura dell'Università di Palermo e finalizzata all'individuazione di possibili scenari e di visioni progettuali per il recupero del complesso della centrale termoelettrica "Tifeo" di Augusta, significativa opera di Giuseppe Samonà. La ricerca sottolinea come progetto architettonico e progetto di paesaggio risultino (anche in questo caso) inscindibili e legati da stringenti refluenze reciproche: restauro dell’edificio e “restauro” del paesaggio si presentano come azioni concorrenti e interagenti, mirate verso un unico obiettivo comune, che può attuarsi solo attraverso una rifless…
