“…Las armas nucleares tienen diferentes capacidades de energía que se miden en kilotones y megatones, un kilotón equivale a 1 000 toneladas de trinitrotolueno (tnt) y un megatón a un millón de toneladas de tnt (Siracusa, 2015). Un ejemplo de kilotones son las dos ojivas utilizadas en las ciudades de Hiroshima y Nagasaki, las cuales contenían un rango de 15 y 21 kilotones (Malik, 1985).…”

El objetivo de este artículo es analizar las regiones-ciudades fronterizas entre Estados con armas nucleares y Estados sin armas nucleares para una propuesta de norma de protección orientada a prevenir el riesgo de ataque nuclear. La investigación identificó Estados, cantidad de ciudades y de población de las regiones fronterizas y comparó la cantidad de población de las regiones fronterizas con la población cubierta por los tratados de zonas libres de armas nucleares y los tratados de regiones-áreas geográficas libres de armas nucleares. El estudio analizó las consecuencias humanitarias de una hipotética detonación nuclear en una región fronteriza entre Estados Unidos y México (caso Tijuana-San Diego) y sus implicaciones geopolíticas en la seguridad internacional. Las conclusiones exponen que las regiones fronterizas son vulnerables ante la ausencia de normas, y la propuesta es viable para la creación de una norma internacional de protección compatible con los tratados que buscan el desarme nuclear.

“…Fusion processes and their uses (reactors [1,2] and devices [3]) have gained popularity recently owing to their effectiveness in producing large amount of energy and radioactive particles [4]. They have evolved from their initial designs to more compact and robust devices with greatly enhanced coupling to targets, possibility to drive powerful shaped charge jets and forged fragments, enhanced prompt radiation effects, reduced collateral damage and residual radioactivity.…”

Fusion device and its structure may be designed by various means. Two of most popular are; weight basis (described in previous study by author) and energy basis. In present research, later method is explored and described. Energy basis is based on amount of energy released from device upon detonation followed by explosion. Its beneficial in a sense that device size can be kept as independent variable as compared to dependent in former case. Further, it shortens the design procedure. For example, heat transfer pattern in such approach directly helps in quantifying wall thickness which dictates material, fabrication, and manufacturing route. It may also eliminate anisotropy as wall thickness is direct function of amount of heat at which it will rupture and can be much thinner. Device geometry can also be flexibility controlled as it is no longer dependent on pay load bay capacity. This allows more freedom in designing subsystems (compartments, their locations, focusing, switches, and mixers). Such devices can be more compact and simpler. Few such design configurations are proposed.

“…It is fuel efficient, quick, and voluminous process with ability to be scaled up and controlled to yield high amount and throughput of energy. In its native form, it may be harnessed to build reactors (contained devices) or untamed form to build devices [1][2][3] which is an area of interest here. Historically, these devices have been made in many ways such as famous cylindrical configuration (Teller -Ulam design (Fig 1)) [4], modified Teller Ulam design (Ivy Mike (Fig 2 and 3)) [4], oval, cone and dual cone configuration [5][6][7] all on the basis of principle to contain plasma [8] or x-ray shock wave produced, focus them (e.g.…”

With recent developments in fusion engineering, interest has sparked in development of fusion devices for deterrent. Enormous amount of energy generated by combining two light nuclei could be contained and manipulated at will to trigger and accelerate micro explosions (from shock wave, x-rays or ion beam focusing) which finally result in full scale blast. Materials required to make such device are critical. They must possess high strength, high hardness, ductility, formability, drawability, and anisotropic properties. High entropy alloys (HEA) are new class of materials which nicely fulfils this requirement. Essentially, they are solid solutions of multi principal elements (usually > 5) eliminating the need of base metal as in conventional alloys. This gives them many unique properties which may be tailored at will (heat treatment, cold rolling, precipitation, irradiation). They also exhibit excellent directional properties with formation of distinct bands along certain preferred crystallographic planes even in hexagonal close packed structures. These anisotropic properties are strong function of rolling, working, or forging (swaging) direction and can be utilized to benefit. This study encompasses making outer shell of a typical fusion device selected on the basis of the weight, which is a function of area of pay load bay of carrier aircraft.
