Fission reactions can be run continously to generate electric power commercially because?

A steady state chain fission reaction is set up in the reactor, when just enough of the neutrons released in each fission is captured by other fissionable nuclei to keep the number of fissions occurring every second at a constant level. Thus the reactor power is held at a steady level. The reactor in terms of nuclear properties is then said to be "critical". As operation proceeds the U-235 gets used up, but this is counteracted to some extent by the production of plutonium from U-238, the plutonium also being fissionable. Eventually the reactor runs out of fissionable material and has to be refuelled, but this can be only at intervals of two years or so, between these refuelling outages the power output can be maintained continously.

Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
How does the highest discharge of an electric eel compare with the voltage that comes out of a normal wall socket?
An electric eel can, in theory, generate burst of 1 Amp at 500 volts, which is more than enough to kill a human that is close enough. They only generate 300 microwatts on a continuous basis.
What kind of tissues generate electrical signals?
The types of tissue that generate electrical signals would have to be examined on a case-by-case basis. There are a number of creatures that are bioluminescent, that generate light (which is electromagnetic radiation). And there are electric eels and electric catfish that generate a "pulse" of electrical energy. Additionally, many organisms have nervous systems that generate electrical signals as part of their nerve function. The variety of tissues that generate electrical signals varies widely depending on what kind of electricity or electrical signal is being generated. These tissues can generally be studied only individually, as the mechanism of electrical generation by one may be significantly different than that of another.
What type of reactions can generate the most energy of nuclear?
Fusion and fission nuclear reactions.

Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
