are fusion reactors the clean power plants of the future?

Question

fusion power plants are renewable and safe energy sources that does not cause much/any harm to the environment, unlike many other forms of renewable energy e.g. wind (damages scenery) and hydro-electric (flood area). Fusion technology also promises high energy out puts once it is perfected (major drawback of solar panels) fusion reactors are relatively safe to operate since the fusion reaction is very fragile and any irregularities will cause it to stop ( unlike nuclear reactors). so, are there any drawbacks to fusion technology?

Answer 1

Number 1 drawback is: we don't know how to make them yet. Very qualified scientists are working on them, but some equally qualified scientists claim that any investment done in that field is a waste and that controllable, practical fusion is an impossibility. I do wish those are wrong that that fusion is possible, for all the good reasons you mention.
Now, second drawback, assuming that it IS feasible, is that at least the first practical reactors might be horribly expensive to build and operate. If they are not competitive from a cost point of view with alternative source of energy, investment will not be made at a rate that allows development of the approach.
A last point to remember: if the fusion involves a deuterium-tritium reaction (which is the easiest one to ignite) one requires the facilities to produce tritium, and that usually involves fission reactors. Also, the DT reaction does release neutrons, and that will tend to make at least the reactor core slightly radioactive. The proton-proton reaction is a lot more cleaner, but is also a lot more difficult to achieve (requires higher temperature and better confinement).

Answer 2

Although fusion power plants will generate small amounts of radioactive material due to the high energies involved (the reactor shielding material becomes radioactive after a while), it is considerably less than a fission plant, and the half life of the waste material is considerably less than spend uranium fuel rods, therefore it will be safe much sooner.

By their very design, a fusion power plant cannot "meltdown". Unlike a fission plant which always wants to produce more energy, and the reaction has to be forced to slowed down, a fusion plant can be turned off simply turning off the fuel supply. No fuel, no reaction.

Answer 3

Gosh. it somewhat is an exceedingly great tale. i ask your self even with if it somewhat is ever instant interior the college kit. i think of of the colleges are little heat beds of budding socialists. you're able to learn Ayn Rand's "We The residing". a great little novel set interior the U.S. of the 19 Nineteen 1920s. that they had replace, merely as we are having now. yet particular, it somewhat is exactly the line we are occurring. The heads of companies, the leaders of industry, the self made millionaires, the persons who artwork no longer user-friendly and pay their own mortgages and save to furnish their youthful babies to college are people who're being denigrated now and are going to could foot the bill for Obama's huge money grab. they are the spine of this u . s ., the individuals that pay the expenses, the persons who look after themselves and their own. share the wealth! And somewhat quickly there will be none. inspect Zimbabwe. They did an identical challenge. Took the criteria out of the palms of the evil prosperous white people. Now inspect them. They shared the wealth and now they are starving.

Answer 4

I think so, because even many people say the nuclear plants are dangerous, if you verify since the first plant was built, the quantity of accidents are really small.
