The question “can nuclear energy be made available by use of the fission process” is investigated. An analysis of the problem is made in which a mixture of uranium and water or paraffin is considered. The necessary conditions for a chain reaction to take a place are obtained in terms of U, the number of atoms or uranium per atom and C 5 the isotopic U ...

A Deep Learning Approach to Anomaly Detection in Nuclear Reactors
IEEE International Joint Conference on Neural Network, 2018In this work, a novel deep learning approach to unfold nuclear power reactor signals is proposed. It includes a combination of convolutional neural networks (CNN), denoising autoencoders (DAE) and $k$-means clustering of representations.

JAMA: The Journal of the American Medical Association, 1973
To the Editor.— A letter from Mr. Mustard commenting on nuclear reactor safety appeared inThe Journal(223:1158, 1973). His letter is full of errors of fact as well as interpretation. Mr. Mustard's letter begins with a reference to "the fallacy of coal-fired plants creating radioactivity," and "the fact is that coal-fired plants emit no fission ...

Electrical Engineering, 1963
The coupling of nuclear reactors with thermionic converters is reviewed. First, the paper discusses principles of operation of thermionic converters, together with present and anticipated advancements. Particular emphasis is given to parameters that influence optimum performance and life of converters; namely, work function of emitter and collector ...

Reviews of Modern Physics, 1999
The story of fission is a story of drama and emotion, and it is a story that demonstrates possibly better than any other the overwhelming importance of modern physics to the events of this past century. Its discovery, or more properly, its identification, was delayed for a surprisingly long time after the phenomenon had in fact been induced in several ...

Is there a Nuclear Reactor at the Center of the Earth? [PDF]
Earth, Moon, and Planets, 2006 In this paper we discuss the Herndon hypothesis that a nuclear reactor is operating at the center of the Earth. Recent experimental evidence shows that some uranium can have partitioned into the core. There is no viable mechanism for the small amount of uranium that is dissolved in the molten metal to crystallize as a separate uranium phase (uranium ...

Small Modular Nuclear Reactors
2020Small modular reactors (SMRs) encompass a large number of technologies at different stages of development. A key challenge for SMR stakeholders is the evaluation of SMR competitiveness with respect to large reactors (LRs). SMRs are usually considered less competitive than LRs because of a misguided application of the economy of scale principle. However,
