Nuclear research reactors are often found in open pools, allowing visibility of the core and the bluish luminosity of the Cherenkov radiation. In general, t he thermal energy released in these reactors is monitored by chambers that measure neutron flux. There are other methods used to measure the power, including: nitrogen formation, measure of the fuel rod central temperature, and the energy balance in the heat exchanger. The brightness of Cherenkov radiation is caused by the emission of visible electromagnetic radiation (in the blue band) by charged particles that pass through an insulating medium (water in research reactors) at a speed greater than that of light in this medium. The objective of this research is to propose, design, and assemble a prototype of an equipment, which uses an innovative and alternative method to monitor the power of nuclear research reactors by measuring the intensity of luminosity generated by the Cherenkov radiation produced within and around the core. An Arduino Uno board was used, with color and luminosity sensors. The work was performed simulating and monitoring experimentally in laboratory, the intensity of luminosity generated by the Cherenkov radiation. The prototype presents potential as an auxiliary methodology for measuring thermal power of research nuclear reactors. It is intended to use this measurement system in the IPR-R1 Triga reactor of the Nuclear Technology Development Center -CDTN (Brazil).
The race for electrification and the need for innovation to attract customers has driven the automotive industry to do something different in vehicles, emerging emission control challenges and efficient technological availability are the pillars of innovation. With the need to upgrade industrial manufacturing systems, directly impacting vehicle production, established the search for new prototyping methodologies and use of virtual tools for testing, validation of components and vehicle systems are developed. The demand for electronic components controls units (ECU) is growing, due to the availability of intelligence and security in today's vehicles, directly impacting their development and the performance and functionality tests. To meet this new reality, in addition to the automotive test prototypes used during development, the automotive industry has been using different virtual environments to produce, verify, and validate its vehicles. Therefore, this paper applied integration and validation using the HIL test platform, focusing on the ECU Body Control Unit (BCM), analyzing its functionalities and possible failures of the internal and external light loads. After, a brief commentary will be made exposing other test medium platforms given as the Plywood Buck (PWB), checking the reliability, flexibility, installation time, and costs of the three test platforms Software in the loop (SIL), Model in the loop (MIL) , Hardware in the loop (HIL), in order to verify their advantages, challenges, and problems in the use and information to optimize the use of each platform and test medium.
