Finnish LDR-50 SMR (Small Modular Reactor)-nuclear reactor produces only district heating.

Finnish LDR-50 SMR (Small Modular Reactor)-nuclear reactor produces only district heating. But it's possible to connect energy production units to those reactors. 


Finnish LDR-50 SMR (Small Modular Reactor)-nuclear reactor produces only district heating. That reactor is called LDR-50. And its mission is being stripped from turbines and other things. The cooling of the reactor base is in the water's natural water cycle. At this moment, I must say that the turbines can also installed in the water cycle. Or the district heat water cycle. When we talk about energy, we must realize that the difference in temperatures and vapor pressure are things. That makes energy.

If there is a thing like a closed cycle turbine that uses liquid helium or liquid nitrogen to rotate the turbine wheel, that system can also produce electricity. The difference in temperatures is an interesting thing. If we lived on  Pluto our bodies would give us enough energy. It vaporizes liquid helium to pressure, which can rotate turbogenerators. Those SMR-reactors can have many possibilities. Advanced turbines can installed anyway in the reactor's water cycle. 

The nuclear waste also can give temperature for turbogenerators. That uses liquid helium or nitrogen. And nuclear waste's temperature will vaporize those liquid gases. 

In some visions, the nuclear waste disposal site can also be used as a power plant. The system benefits liquid helium or nitrogen that rotates in a closed cycle. The nuclear waste's heat will vaporize that liquid gas that rotates the turbogenerator. The systems that use nuclear waste as a power source are not very common.

"TRISO particles can withstand extreme temperatures well beyond the threshold of current nuclear fuels". (TRISO Particles: The Most Robust Nuclear Fuel on Earth)



The nuclear fuel called TRISO (Tristuctural-isotropic fuel)


The TRISO means the balls where there are three layers. Those layers are ceramic, graphite, and nuclear fuel isotopes. The graphite layers can include two layers. Regular graphite and the outer layer would be carbonite crystals. Or the structure can be in the artificial diamond. 

The most out layer would be a strong ceramic structure. If there are some problems. The reactor simply removes part of the TRISO balls. That should stop the nuclear reaction because the lack of half of the fuel turns the reactor into a subcritical condition. And when the problem is handled, the system returns those TRISO balls to the reactor. 

The Subcritical nuclear reactors require a laser or some other electromagnetic heater. So they are a little bit like thorium reactors. The laser or microwave beams keep the nuclear reaction on. If those electromagnetic systems will shut down that thing stops the entire reaction.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
