It’s blue for a reason! 🔵🤩 This is the view inside the Penn State Breazeale Nuclear Reactor, and that iconic blue glow is the Cherenkov radiation, which happens when charged particles travel through the reactor water faster than light. ✨⚛️ #PennState #PennStateEngineering #NuclearEngineering #PennStateNuclear #NuclearScience #NuclearReactor #CherenkovRadiation

Nuclear Reactor and Cherenkov Radiation/Effect. In Nuclear Fission Power Plants, civil electricity/energy is produced by the reactor ( usually, there is more than one per plant). A nuclear fission reactor is a type of nuclear reactor capable of managing a chain fission reaction in a controlled manner, starting from fissile material , in order to produce electricity from the heat released during fission. So ... This is what happens in nuclear power plants. In the reactor , the chain reaction is fed and controlled by neutron bombardment to the fissile fuel ( usually uranium/enriched uranium/plutonium ) placed in bars in the core ...unstable radionuclides decay into lighter nuclides releasing energy and ionizing radiation☢☣ To control the reaction, neutron absorbing control bars( cadmium/boron/silver), moderators (heavy water , graphite) , coolant and containment concrete layers are required. ☆And the light we saw in the video ? The Cherenkov radiation!!! The Cherenkov effect occurs when a particle carrying an electric charge travels faster than light through a transparent and specific medium like water . If the particle travels faster than light in this medium, its passage causes a brief and attractive blue or violet flash of light. In the field of radioactivity, the particles concerned by the Cherenkov effect are electrons and positrons. Very light, they reach very high speeds. In water, the speed of light is 200,000 km / sec. ....there are other particles that don’t slow down as much and end up moving faster than light. ☆ 🌐FOLLOW @glamour_physics ☆ 🌐Credits clips used in editing: JSI TRIGA Research Reactor (YouTube) Triga, Pulse operation, Nuclear reactor 240 MW, 7.12.2012: MrStankoman ( YouTube channel) 🌐CREDIT COMPOSITION EDITING @glamour_physics @modernsciencex CONTENT USED FOR EDUCATIONAL PURPOSES ONLY ☆ All Rights And Credits Reserved To Respected Owner (s) No copyright infringement intended Issues?

Briefly: The image shows the test rods of the Chernobyl Nuclear Reactor. In the image on the left, they appear as they should, but their irregular appearance in the image on the right suggests a problem. More awaits you in my account! For those who are curious: The control rods at the Chernobyl Nuclear Power Plant played a critical role in the 1986 accident. Their primary function was to slow down or completely stop nuclear fission in the reactor. Control rods are made from neutron-absorbing materials such as boron, silver, and indium, and as they are inserted into the reactor core, they suppress the chain reaction. The control rods in the RBMK-type reactors used at Chernobyl had a serious design flaw. The tips of the rods were not neutron absorbers, but made of graphite. Graphite is a material that slows down neutrons, increasing the probability of fission. Therefore, when the control rods first entered the core, instead of calming the reactor, they briefly increased reactivity. During the 1986 experiment, when the emergency shutdown system was activated, the control rods simultaneously began descending into the core. However, because the graphite tips entered the core first, a sudden and very powerful surge of power occurred at the bottom of the reactor. This unexpected surge became uncontrollable within seconds, triggering the process that led to the reactor's explosion.Furthermore, it took a considerable amount of time for the control rods to fully enter the core in RBMK reactors. This slowness made it difficult to quickly shut down the reactor in an emergency. Both the graphite tip design and the mechanical delay transformed the control rods from a safety device into a significant part of the disaster in the Chernobyl accident. Following the accident, the design of the control rods in RBMK reactors was modified, the graphite tips were removed, and the emergency shutdown systems were accelerated. This event is considered one of the most striking examples of how even seemingly small details in nuclear reactor design can have enormous consequences. #Chernobyl #nuclear #mystery #reactor #scientific less

Lo que ves en este video no es solo una estructura bajo el agua… es el núcleo de un reactor nuclear de investigación operando con precisión milimétrica. Dentro de estas instalaciones, cada segunda cuenta: temperatura, radiación, flujo de neutrones y presión son monitoreados en tiempo real mediante sensores, cámaras y sistemas computarizados. El agua cristalina no está solo para enfriar: también actúa como una barrera natural contra la radiación, permitiendo a los científicos observar el reactor con total seguridad desde arriba. Este tipo de reactores no se usan para producir energía masiva, sino para investigación avanzada, producción de radioisótopos para medicina, estudios en física de partículas y entrenamiento técnico.

Una bomba nuclear libera energía a partir del núcleo de los átomos, no mediante reacciones químicas como los explosivos convencionales. La diferencia clave está en la escala: la energía nuclear es millones de veces más potente. En las bombas de fisión, el proceso se basa en la división de átomos pesados como el uranio-235 o el plutonio-239. Cuando un núcleo se rompe, libera energía y neutrones que provocan nuevas divisiones en otros átomos, generando una reacción en cadena extremadamente rápida. Esa liberación súbita produce calor extremo, radiación intensa y una onda expansiva devastadora. Las bombas de fusión funcionan de otro modo. En lugar de dividir átomos, unen núcleos ligeros, generalmente isótopos de hidrógeno, para formar uno más pesado. Este proceso, que es el mismo que alimenta al Sol, libera todavía más energía. En este tipo de armas, una explosión de fisión inicial sirve para activar la fusión, multiplicando su potencia. Los efectos de una detonación nuclear incluyen temperaturas capaces de vaporizar estructuras, una onda de choque que destruye todo a gran distancia, radiación inmediata letal y contaminación radiactiva persistente que puede afectar al entorno durante décadas. Por eso, más allá de su uso militar, las armas nucleares representan un riesgo humano, ambiental y político global. Comprender cómo funcionan permite entender por qué su existencia sigue siendo uno de los mayores dilemas de seguridad y ética del mundo moderno.

When a nuclear reactor powers on for the first time, the core fills with a deep blue glow that feels almost unreal as it rises through the water in a quiet surge of energy. The light is Cherenkov radiation, created when charged particles move through the water faster than light can travel in that medium, a discovery made in the 1930s that revealed a new way to see high energy reactions. Every appearance of this glow is a reminder of how powerful atomic reactions can be, showing a rare moment where raw physics becomes something visible and strangely beautiful. Love tech?

Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. #science #nuclear
