It is well known that safety in the operation of nuclear power plants a primary requirement because failure this system can result serious problems to environment. A reactor has several systems help keep it normal operation, within margins. Many these operate control variable quantities circuit reactor. However, reactors are nonlinear physical systems, and introduces complexity strategies. Amon...

Chemical Looping Combustion (CLC) is a low-cost CO2 capture technology highly competitive for industrial and energy applications. Up to date, CLC has been mostly developed at atmospheric pressure. Pressurized may bring additional advantages due the intensification of process. The main objective this work was determine whether an increase in operating pressure could improve fuel conversion syste...

The effect of organic loading rate (OLR) on a pressurized anaerobic filter was studied in a laboratory two-phase anaerobic digestion system. The anaerobic filter was operated successively at two working pressures (9 bar and 1.5 bar). The OLR(COD) for each pressure was increased from 5 to 17.5 kg·m·day. The best performance of the reactor at 9 bar was observed at OLR(COD) of 12.5 kg·m·day and hy...

Today, most software applications, also in the nuclear field, come with a graphical user interface. Recently, the Symbolic Nuclear Analysis Package (SNAP) was designed to simplify the process of performing safety analysis. The purpose of the present study was to develop an SNAP animation model for RELAP5 calculations of a nuclear installation. The facility selected was the Rig of Safety Assessm...

Fuel cycles are designed with the aim of obtaining the highest amount of energy possible. Since higher burnup values are reached, it is necessary to improve our disposal designs, traditionally based on the conservative assumption that they contain fresh fuel. The criticality calculations involved must consider burnup by making the most of the experimental and computational capabilities develope...
