The steam from one nuclear circuit heats a secondary, non-radioactive circuit. But isn't an incredible amount of energy lost in the process? So why not simply shield the turbines better and use the steam from circuit 1 instead?

Loading...Hi, this is probably a really stupid question, but I'd like to ask it anyway because I find the concept quite funny. Why wouldn't the following scenario work?
My parents are very strict and don't want me to drink Red Bull. My brother and I bought 24 cans and don't know where to hide it. We have a large outbuilding with an attic where we're hiding it now. Where could we hide it so no one finds it?
Connect the 1000 microfarad capacitor in series with the lamp and the switch to the DC output of the power supply (10 volts). Operate the switch. Observe the lamp. What do you notice? Edit: Maybe I should have phrased my question better. I've already conducted this experiment and observed exactly what you all think, but…
A button is connected with 4×1.5mm² (brown, black, blue, and green/yellow) The brown (L) and green/yellow are clear. Currently, the blue wire is used as the sensing wire in the old circuit. And the black wire isn't connected. Should I rewire the button and use the black wire as the sensing wire?
Hallo. Das was du beschreibst ist ein klassischer Druckwasserreaktor. Es gibt auch Kraftwerke mit nur einem Kreis, mit dem Nachteil das auch die Turbine radioaktiv ist. diese Kraftwerke heißen dann Siedewasserreaktor. Deutschland hatte beide Modelle am Netz. Die neuen Kraftwerke sind fast nur noch Druckwasserreaktoren. Grüße

The second circuit is the cooling circuit. The turbines are driven directly by the first circuit, and the contaminated water is then cooled with the other water (usually river water). This water then evaporates from the cooling towers or returns (heated) to the river. It would be unwise to disperse all that radioactive material all over the world through the cooling tower.
das ist nur bei Siedewasserreaktoren so. Bei Druckwasserreaktoren sind Reaktor und Turbinen in getrennten Kreisläufen.
bitte Frage ganz lesen …
Everything that requires access for maintenance purposes is kept out of the reach of contamination whenever possible, otherwise, every loose screw would require a scheduled overhaul. Incidentally, hardly any energy is lost in the heat exchangers between the circuits (where would it go anyway), and the temperature level in the secondary circuit is already close to the upper limit of what the turbines can withstand.
Because the turbine needs maintenance. And that's impossible if it's radioactive.
I assume this is so that the first circuit does not contaminate the turbine and other things.
Weil sonst der gesamte Turbinenkomplex incl. Rückkühlung radioaktiv verseucht wäre.
Gäbe es keine zwei Kreisläufe, würde man permanent radioactiven Dampf an die Umgebung abgeben.
Even in boiling water reactors, where the reactor and turbines are in the same circuit, the cooling water circuit is separate. And no one would expose the turbine blades to steam from dirty river water. So, in pressurized water reactors, there are three circuits in total.
Und wer sollte dann die Turbinen reparieren und austauschen? Jeder verdammte Wasserhahn wäre hochradioaktiv.
