Study of the demand-supply for radiopharmaceuticals in IPEN
2019 - MUTARELLI, RITA de C.; LIMA, ANA C. de S.; SABUNDJIAN, GAIANE
Radiopharmaceuticals are unique medicinal formulations containing radioisotopes and are used in nuclear medicine for diagnosis and/or therapy for chronic diseases such as cancer, alzheimer and cardiac disorders. The increase in the incidence of these diseases in the Brazilian population and the trend of increasing demand for radiopharmaceuticals motivated the elaboration of this work from a system dynamics perspective. The aim of this paper is to present a System Dynamic Model for simulating the interaction between demand, capacity, workforce and production of radiopharmaceuticals produced by IPEN. The validity of this model is verified by running in Vensim PLE software using historical data. The model was based on the generic structure of commodity markets and main variables were considered to represent the market polices. The preliminary model presented was able to capture the expected behavior of the industry of radiopharmaceuticals. Two alternative scenarios were developed, one to analyze the impacts of investment in infrastructure of IPEN and the other to investigate the workforce investment. As result, the model performed well in representing the behavior of the market. In addition, scenario tests showed that investment in infrastructure and workforce investment have a significant impact in the dynamic of the system.
Sustainability
2019 - BARABÁS, CARLOS; LIMA, ANA C. de S.; SABUNDJIAN, GAIANE
Over the years, sustainability has been a major theme discussed by the leading environmental organizations around the world. Excessive consumption is one of the factors that is directly connected to environmental issues, interfering with the sustainability capacity of the Earth. Attitudes and behavior are influenced by both conscious (explicit) or unconscious (implicit) associations that subjects have in their memory. In order to identify unconscious associations, specific implicit memory tests are required, such as the Implicit Association Test (IAT), which is widely used to measure implicit associations towards several themes. This work aims to present the results from a pretest using the IAT to identify and measure the implicit associations of a group of environmental specialists regarding consumption and sustainability. By using the FreeIAT software, the IAT was customized for this research. The pretest with environmental specialists was conducted to check the consistency of the customized IAT. The Cronbach´s alpha was applied to measure the reliability of the test and showed good internal consistency. Since the results from the pretest with the specialists demonstrated that the customized IAT is reliable and consistent, this test can be applied to other groups of subjects to identify the implicit associations towards consumption and sustainability. The data obtained from the administration of the customized IAT will contribute to many research fields related to the environment, consumption, sustainability, energy and development.

Study of the economic viability of the innovative nuclear reactor SMART in Brazil
2017 - ESCANHOELA, CORDELIA M.F.; LIMA, ANA C. de S.; SABUNDJIAN, GAIANE
The main objective of this study is to evaluate the economic viability of the installation and operation of the innovative System - Integrated Modular Advanced Reactor (SMART) in Brazil. SMART, developed by the Korea Atomic Energy Research Institute (KAERI), is a small and modular Power Water Reactor (PWR), presents electric power of 100 MW and thermal power of 330 MW; it has a passive safety system and integral refrigeration configuration, characteristics that, allied with modularization, simplification and technological improvements, give SMART greater reliability and economy when compared to conventional reactors. SMART presents, in addition to electricity production, the functions of seawater desalination and district heat generation. The research is based on projections of energy demand in the medium and long term with emphasis on electricity and search for the reduction of greenhouse gases. These previsions indicate the need for energy expansion and diversification of the current sources in Brazil, predominantly water sources. The methodology used is based on the cost of electric generation, production capacity and construction time of SMART, adopting the investment model similar to the Angra 3 plant and the use of mirrored costs between the plants. The feasibility of the project was evaluated through the financial criteria: Internal Rate of Return (IRR), Net Present Value (NPV) and Weighted Average Cost of Capital (WACC), whose revenue should be generated through a tariff passed on to the consumer.
