Public perception of the nuclear area in Brazil
Nowadays human dependence on electricity is increasing and as a result access to energy resources and / or energy, is becoming a priority in most countries, both developed and developing. With this comes the need for government involvement in the planning and expansion of energy activities, especially when dealing with nuclear energy. This study makes a detailed assessment of the availability of energy and its capacity, the geographical location of current and future nuclear plants, economic criteria, the deployment period and public opinion concerning the construction of new nuclear plants. The aim of the study is not only to show the advantages of the expansion of nuclear energy in Brazil but also to evaluate public opinion on this issue
Determination of uranium and zirconium by flow injection analysis
As an integral part of chemical quality control of nuclear materials a method for determination of uranium and
zirconium, in a mixture is presented. A simple, cheap, selective and quantitative Flow Injection Analysis (FIA)
system was developed. Zirconium and uranium were determinate in presence of each other and no prior
separation was needed. Arsenazo III was used as a colorimetric reagent and parameters such as acidity and
reagents concentration were studied and optimized. An analytical throughput of 30 sample determination per
hour was obtained
