Let's do the math...

Average Nuclear Generating station is 1 Gigawatt, which is 1,000,000,000 Joules per second. Even assuming no thermodynamic losses, you would need 245lbs of coal (at 4,068,000 Joules per pound) per second to sustain that. So, just to feed the fire you would need 245 lbs. x 60 seconds x 60 minutes = 884,955 lbs of coal per hour 24/7 to sustain it.

That is actually a doable number, but not in the footprint of a nuclear reactor. The amount of coal for an hour of running would be a pile of 10,171 ft3 or 10' wide x 10' high x 101' long. So, whatever is inside that containment building has an energy density many times that of coal.

Your math is ballpark correct but you're using globalist units :)

The large nuclear units evaporate about 8 million lbm/hr of water at around 1000 psia. Enthalpy of evaporation at that pressure is 650.4 Btu/lbm, so the unit is using 5,203,200,000 Btu/hr to evaporate that water.

Now coal has varying heating values depending on the grade. Hard anthracite is around 13,700 Btu/lbm. Bituminous is around 14,300 (higher because it has more volatiles - flammable gases). Lignite (which the Krauts love to burn) is only 7200 due to all the water in it. Let's be generous and use the highest value - bituminous - which will result in the smallest weight of coal to burn. This comes out to 363,900 lbm/hr or 101 lbm/sec.

This big difference is due to your assumption of 4.1 MJ/lb. It's off by a factor of three as far as good U.S. coal is concerned (4.1 MJ/lb --> 3856 Btu/lb).

But to the main point, now determine the volume of coal for 18 months of operation. Won't fit in containment :)

Good grief you guys and your 'math' ... and if any idiots don't understand what we're saying then you're stoopid and we win the argument. LOL.

My kid has a master's degree in engineering and my sis in law is a math professor, you sound like them lol.

To an extent yes but that wasn't my point really (but I take yours).

those maths don't add up. Takes way less to boil water. The main problem though is no proof, it'd be cool if you took video from inside showing this steam and the generators. I am guessing you don't actually have access to it, you're a janitor at best. Or yeah you're probably afraid you'd lose your job by showing proof. But they keep nuke plants secret for a reason.
