Of this form, Alcade (1985) observes a similarity enters the structural system of the gtica architecture with the modernista architecture, where both possess not structural walls that can be transformed. Into the case of the modernista architecture, these can be transformed into glass walls. It is had that the European modernistas had faced difficulties to work with the new technologies of the modernista architecture, a time that confused the technology with a cultural problem, relating the changes of style with the technological changes. Brawne (1960) already affirmed that the concern of the Bauhaus was with the rational production of the object and not with the user, as for example, when searching the way simplest to produce a lights without if worrying with the light that happened in its eyes. On the other hand, century XX assumes the importance of the light, claim this carried through during the previous century. Cremonini (1992) quotation that the new period was characterized by new technologies, as the plain glass – allowing innumerable possibilities related with the compositivo direction of the workmanship; brise- soleil and the light shelves? dialoguing construction with the natural light by means of a glass skin. The author also emphasizes the importance of the light in century XX, that he left of side the symbolic significaes and followed route to a impressionista vision. According to Mascar (2005), another technological advance of utmost importance for the illumination of interior spaces in the architecture was launched in the end of the decade of 1940, with the incorporation to the market of the light bulb of fluorescent pipe for artificial illumination, which, together with the light bulbs of gas discharge, existed potentially since the start of century XX. For the project architectural, this innovation represented the creation of rectangular low plants with spaces integrated through the luminous lining, with the land installations and the circulaes placed in the center of the rectangular plant.
In the last days, the world comes intently observing the radioactive problems that had appeared in Japan, due to the happened natural accident in that small country. He is not of today that the North American model of life influences countries in all the continents generating consumption excess, causing a necessity in the magnifying of the natural energy production. To supply this lack, forms of alternative energies had been created having as one of the examples to the nuclear plants. The first idea of the nuclear reactions appeared in the dawn of 16 of July of 1945, when the first nuclear test of the history, carried through in the desert of Alomogordo, New Mexico occurred. Through the ideas of Albert Einstein that dealt with the conversion of mass in energy, some isotopes of certain chemical elements present the capacity to emit energy through its unstable nuclei in search of the nuclear stability. From now on it was observed by the scientists of the time to the possibility of the exploitation and transformation of this type of energy, not but for warlike ends as in the case of the atomic bombs, but for purposes that could have one better exploitation in the day the day of the people. But what it is a nuclear plant? ' ' A Nuclear Plant is an industrial installation used to produce electricity from nuclear energy, that if characterizes for the use of radioactive materials that through a nuclear reaction produce heat. This heat is used by a conventional thermodynamic cycle to move an alternator and to produce energy eltrica' '. (1) the nuclear central offices present one or more reactors, that are impermeable compartments to the radiation, in whose interior mineral bars or other configurations are placed geometric with some radioactive element (in general the Uranian one). In the process of radioactive decomposition, if it establishes a reaction in chain that is supported and moderate by means of the use of elements auxiliary, depending on the type of employed technology.
