It is hard to imagine a nuclear power plant and all the money that goes into building one for the sole purpose of heating water to create steam to run steam generators.
Surely there is a more economical way to heat water.

No one has found a cheaper way yet. It looks as if it may be decade or even centuries before any source of energy is found that is cheaper, safer and in adequate supply for the worlds energy needs.

They are not jus heating water. It is a complex process that allows this steam to have high amounts of energy to turn very large turbines. nuclear plants may be expensive to build but the advantage to the enviroment and use of a bountiful resource like uranium, far out way the expense. Especially with the depleting supply of coal or oil that we are so dependent on now.

Its purpose is to generate electricity, as well you know, not to heat water.

And, yes, at present there is a "more economical way". It's called coal; it requires the destruction of vast swathes of countryside, kills miners in its extraction, wastes energy in its transportation, kills thousands with its exhaust and alters the atmosphere of our planet more than any other process.

But, on simple finance, it's cheaper, which seems to be all you're interested in.

It's cheaper because they externalize their health costs.

E.g., I pay for my daughter's inhaler, and we all pay for the care of MEDICARE/MEDICAID enrolled COPD (chronic bronchitis) patients.

the nuclear waste is an issue though. Ask up around WA how they're doing on that. Likely to polute countryside and water. They know no way to dispose of this waste from uranium.

Jessie you are talking about the waste at hanford which is from the production of nuclear weapons. You are right this is not a good situation but it is being cleaned up by DOE. Should have been done sooner but High level waste (fuel) is not the material that is in Hanford's tanks

You perhaps are correct. I thought it around Richland(?) I noted a few yrs. back, this was waste eating through thick steel tanks fixing to start leaking into the area...and yes, this was from WWII...I think. Can't remember as exact as I did. I did know DOE was sending funds up there and 'creating' so many jobs. Just a concern.

Exactly. So "simple finance", as I put it, is not a very good measure of which system is preferable.
