Homework Statement
A steam-electric power plant delivers 900 MW of electric power. The surplus heat is exhausted into a river with a flow of 5.51×105 kg/s, causing a change in temperature of 1.35 oC.
What is the efficiency of the power plant?
What is the rate of the thermal source?

I have a basic understanding about the fissioning process in atom bombs and in nuclear reactors but that's not what my question is about. It's about a nuclear pile of a radio-active material. A pile of the element to power a space station of considerable size like say 500,000 Metric Tons. Is it...
Perhaps this is a very stupid question, but why aren't nuclear power-plants built underground?
In a subterranean structure I'm thinking any natural disaster would at worst collapse the cavity without spreading radioactivity.
Are subterranean construction really so intrinsically difficult...
Anyone has ever came across this powerplant? I'm a final year mechanical student, and i was asked to design the turbine blade to harness tp obtain the maximum efficiency of the hydro vortex. I'll be glad if someone can help me out by giving me some vortex calculations,simulations or any related...

A power plant has a power output of 1246 MW and operates with an efficiency of 34.8 percent. Excess energy is carried away as heat from the plant to a nearby river that has a flow rate of 1.4 * 10^6 kg/s.
How much energy is transferred as heat to the river each second...
I was given this problem as an excercise in thermodynamics and to better understand powerplant systems. I am having difficulties because as a civil engineering student I haven't taken a lot of thermodynamics. The one course I did take was several semesters ago and wasn't that advanced...
This is just a question that has been bugging me for awhile, but, in a worst-case scenario, if you say had an earthquake where the ground split open, and a nuclear plant was right over the split, could the reactor literally be "ripped open" in such an instance? And if so, would this cause the...
Nuclear power generator uses radioactive particle emission to stimulate fluorescent material which then lights up photoelectric cell. It's called PIDEC:

Please, write what is wrong with this reasoning:
ATMOSPHERIC POWERPLANT
The main idea of global warming is that greenhouse gases prevent the energy from leaving the surface of planet. In the same time the upper layers of the troposphere are much colder and successfully emit the infrared...
[SOLVED] Nuclear Powerplant Efficiency
Homework Statement
A nuclear power plant operates at 78% of its maximum theoretical (Carnot) efficiency between temperatures of 540°C and 330°C. If the plant produces electric energy at the rate of 1.3 GW, how much exhaust heat is discharged per hour...
I know that confinement and stability are a big issues when it comes to harnessing fusion power in a controlled fashion, but what if we could do away with the stability constraint? (sorry if this is completely unfeasible, I don't really know very much about plasma and discharge physics).

It details the discovery of a 2300 year old battery found in Iraq.
basically it is a pot with some wiring and a copper rod in the middle add some grape wine and you have have a battery capable of generating 0.8 volts.
so here is my question: if this would be cheap to maintain...
