![]() ![]() Next to this theoretical background, a deterministic model is proposed in chapter 3 and in chapter 4 a sensitivity analysis is done on the effect of a varying bismuth capture cross section on the polonium concentration after a period of 90 days, after these 90 days the reactor is scheduled to open for maintenance. In this thesis the theoretical background is provided on the method of characteristics, multiple energy self-shielding methods and on SANDY, a code developed at SCK-CEN to sample nuclear data libraries. Simulations based on Monte Carlo techniques as the neutron transport driving Use these kinds of simulations as first indications. Aĭeterministic method (as opposed to a stochastic method) is expected to provideįaster simulations nevertheless, all this with a lower accuracy. This is why for this thesis the method of characteristics is used. the Nationale Agenda Fotonica (NAF), with a total turnover of 4,2 billion. Monte Carlo methods will require hundreds of days, even with state-of-the-artĬomputers. The Netherlands has a great history in the field of optics and photonics and. ![]() The computational cost is often not prohibitive, but when sensitivity analyses areĭone, many samples are needed, often of the order of 102 − 104 Monte Carlo methods to do sensitivity analysis studies. The companys innovative technology platform offers a revolutionary illumination and analysis system which uses multi-spectral wavelength LEDs in an electrical operation mode, enabling users to increase biomass and quality of crops while reducing energy costs. Strong background (master) in either photonics, electrical engineering. Fotonica is an innovative technology platform designed to assist indoor farming. The goal of this thesis is to implement another method than the widely used Beca de Doctorado FPI en la Universitat de les Illes Balears en Fotnica. MYRRHA uses a lead-bismuth eutectic as coolant and therefore, bismuth 209 is present in large quantities providing the problem of polonium production. The polonium is produced by neutronic capture in bismuth 209. Besides having an estimation of the concentration of polonium, it is also important to have an indication on the possible error on this estimation, which can be done through sensitivity analyses. Especially at times when the reactor would be opened like for maintenance, it is important to know the concentration of polonium. A major challenge of the MYRRHA reactor design is the production of the radiotoxic polonium. For this purpose, a flexible research reactor MYRRHA is currently in design at SCK-CEN. Research is done at SCK-CEN for high level nuclear waste transmutation. Download and use 100,000+ Desktop Backgrounds stock photos for free. High level nuclear waste poses a challenge for society. Plants with different biomass and/or different phenological stages would not all be treated alike, and the same should be said for light.Īs more people throughout the world find their way to the healing benefits of the cannabis plant, there will be more demand on technologies like the Fotonica EVA 3TM system that can not only increase crop yields and cannabinoid concentration levels, but also do so with less environmental impact.SamenvattingThis thesis is situated in the research field of nuclear engineering. It is important to remember that light is just as important a growing component as air, soil and water. Growing indoors offers growers the opportunity to better manage pests, as well as control the temperature, humidity and air CO2 concentration of the growing environment. om het Nederlandse ecosysteem voor gentegreerde fotonica naar een best-in. In his report he stated that “results showed cannabinoid concentration levels that were 20-50% higher (THC, CBG respectively) in comparison to traditional HPS bulbs that were used as control and to standard verity concentration received when grown commercially.” Do you have experience and background of working in a multidisciplinary team. Professor David Meiri of the Laboratory of Cancer Biology and Cannabinoid Research at Technion, The Israel Institute of Technology, recently reported about the EVA3 system. Lighting systems of the past, utilizing HPS or fluorescent light, were originally developed for street or office lighting and were not easily applied or adequate for growing plants, which require a wide spectrum of light. Additionally, light modulation can be performed inclusive of adjustable duty cycle and other light parameters. The smart DLED system provides a fully flexible integrated spectrum curve with 11 bands. Additionally, EVA 3 consume less energy and efficiently converts currents, all while increasing plant biomass and cannabinoids. Israel-based Fotonica recently introduced the EVA 3 DLED (dynamic LED) smart lighting system which utilizes a unique electrical technology that enables growers to implement ‘Light Growth’ protocols that enhance crop yield and reduce energy consumption.ĮVA 3 achieves this by converting electrical currents only to the required wavelengths without exhausting electrons to non-responsive spectrum.įotonica’s EVA 3 adjustable light spectrum allows growers to optimize the use of indoor growing space and reduce human resources as it diminishes the need for two-room operations. ![]()
