Nuclear power plant lecture slides, brief detail of its working principle and its advantages and disadvantages. history and its efficiency are also explaind.
A nuclear power plant or nuclear power station is a thermal power station in which the heat source is a nuclear reactor. As is typical in all conventional thermal power stations the heat is used to generate steam which drives a steam turbine connected to an electric generator which produces electricity.
Enrico Fermi is considered to have invented nuclear power, along with his colleagues at the University of Chicago in 1942, by successfully demonstrating the first controlled self-sustaining nuclear chain reaction.

The 4.2km² site is in the Niigata Prefecture city of Kashiwazaki and the town of Kariwa, approximately 135 miles north-west of Tokyo, on the coast of the Sea of Japan.
Kashiwazaki-Kariwa is also the world's fourth largest electric-generating station behind three hydroelectric plants: Itaipu on the Brazil-Paraguay border, Three Gorges Dam in China and Guri Dam in Venezuela.
Like all power plants in Japan, Kashiwazaki-Kariwa was built to strict earthquake-resistance standards. However, the 2007 earthquake caused the plant to leak radioactive substances into the air and water. The plant, which has been operating since 1985, was closed until safety checks following the earthquake were completed. The plant was reopened in May 2009.
Boiling heat transfer and Core Hydraulics of NPPMd Asif Imrul
In this report, the objective has been set to provide intense view of boiling heat transfer and core hydraulics. In details the aim was to describe the importance and Fundamentals of Nuclear Power Reactors and thermal hydraulic processes involved in the transfer of power from the core to the secondary systems of a nuclear reactor plant and produce competence in the fundamentals of the calculations associated with these processes.
By this process, here it has been included with a short overview over nuclear power plant definition and types, fission reaction, basic hydraulics, over view over nuclear reactor core and their inter relation.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

'The ice is melting much faster than we thought' “ Even if they (opponents of nuclear energy) were right about its dangers, and they are not, its worldwide use as our main source of energy would pose an insignificant threat compared with the dangers of intolerable and lethal heat waves and sea levels rising to drown every coastal city of the world. We have no time to experiment with visionary energy sources; civilisation is in imminent danger and has to use nuclear - the one safe, available, energy source - now or suffer the pain soon to be inflicted by our outraged planet.” - Eminent Environmental Scientist, James Lovelock, The Independent, May 24, 2004

Combustion of 1 atom of C => 4 eV; Fission of 1 atom of U => 200 MeV
In thermal reactors, the fission is caused by thermal neutrons having energy less than 0.025 eV. This type of reactor uses natural uranium as fuel. The neutrons generated during fission posses very high energy which are slowed down with the help of a moderators to reduce the energy of neutrons less than 0.025 eV. In fast reactors, fission is basically caused by neutron possessing energy more than 1 MeV. Another important process that is taking place in the fast reactor is breeding of fissile material.
In the first stage of our programme we have 12 PHWRs and 2 boiling water reactors operating with high capacity ratio. 8 more reactors are under construction and several other are planned to have potential od generating 10 GWe. A fast breeder test reactor (FBTR) of 40 MW thermal capacity is operating and has given us experience in fast breeder reactor technology. In this category, a 500 Mwe Prototype Fast Breeder Reactor (PFBR) is under construction. We have now initiated the third stage also with a 30 MW thermal reactor named KAMINI which uses thorium fuel. As a futher development in this stage an Advance Heavy Water Reactor (AHWR) and Compact Heavy Water Reactor (CHTR) are being developed. The development of ADS I.e Accelerated Driven Systems can enable early introduction of Thorium on a large scale.
