“…Unfortunately GPS typically does not work indoors, thus adding severe limitations on the ability to accurately localize objects indoors. Significant research investments have been made in developing technologies for indoor localization that make use of physical mechanisms such as acoustics/ultrasonic and electromagnetic waves (Chen et al, 2016;Zafari et al, 2018). Unfortunately these technologies often suffer from limitations associated with accuracy and noise in the environment.…”

This work presents a novel, comprehensive framework that leverages emerging augmented reality headset technology to enable smart nuclear industrial infrastructure that a human can easily interact with to improve their performance in terms of safety, security, and productivity. Nuclear industrial operations require some of the most complicated infrastructure that must be managed today. Nuclear infrastructure and their associated industrial operations typically features stringent requirements associated with seismic, personnel management (e.g., access control, equipment access), safety (e.g., radiation, criticality, mechanical, electrical, spark, and chemical hazards), security (cyber/physical), and sometimes international treaties for nuclear non-proliferation. Furthermore, a wide variety of manufacturing and maintenance operations take place within these facilities further complicating their management. Nuclear facilities require very thorough and stringent documentation of the operations occurring within these facilities as well as maintaining a tight chain-of-custody for the materials being stored within the facility. The emergence of augmented reality and a variety of Internet of Things (IoT) devices offers a possible solution to help mitigate these challenges. This work provides a demonstration of a prototype smart nuclear infrastructure system that leverages augmented reality to illustrate the advantages of this system. It will also present example augmented reality tools that can be leveraged to create the next generation of smart nuclear infrastructure. The discussion will layout future directions of research for this class of work.

“…El reto científico consistía en diseñar el mecanismo capaz de comprimir el uranio-235 -o el plutonio-239-hasta superar la «masa crítica», a partir de la cual se libera una cantidad proporcional de energía, según la socorrida ecuación de Einstein: E=M x C 2 (la energía es igual a la masa por el cuadrado de la velocidad de la luz en el vacío). La «masa crítica» depende de las propiedades físicas del correspondiente material físil (en particular, su densidad), su probabilidad de experimentar la reacción de fisión y el número de neutrones que libere al desintegrarse, entre otros factores (Clayton, 2010). Por si fallaba una de esas opciones tecnólogicas, el proyecto Manhattan emprendió ambas al unísono: mientras la opción del uranio-235 impulsó la separación isotópica a gran escala del uranio natural para su enriquecimiento (uranio-235 > 80 %), por su parte la opción del plutonio-239 condujo a la invención de la pila o reactor nuclear para producir este actínido ausente en la naturaleza a partir del uranio-238 (Reed, 2014).…”
