What Vir Modoetiae said. Commercial Nuclear reactors are generally 700 to 1000 MWe per core. The European Pressurized Water Reactor is 1600MWe. A PRISM (fast) reactor is about the right size for the vanilla stats, at 300 MWe per core, and a clear two cores in the plant. At the 'back' of the plant, you can see two 'soda can' like structures. Those are containment cells, with the reactors located at the bottom.

I have no clue where you got the 12000MW figure...if you are referring to net electric power, you would need a 10+ reactor power plant (i.e. a plant which operates 10+ reactors, which does not exists anywhere in the world). The largest power plant in the world is the Kashiwazaki-Kariwa plant in Japan, it has 7 reactors and outputs almost 8000MW of net electric power.
To keep things realistic, I would suggest setting the power of the Cities:Skylines plant to something between 1500MW and 2000MW, as most plants inthe world output between 750 and 1000MW of net electric power per reactor.

@starman, Not all plants. Palo Verde Nuclear Station outside of Phoenix is in the middle of the desert! They utilize the Phoenix metropolitan wastewater treatment plant and enormous draft fans to act as their ultimate heat sink. It's actually very ingenious design, pulling every bit of usable energy from the process.

Excellent nuclear power plant! I suggest 20 000$/week for your power plant,8000$ is too low for 2400mw. 20 000$/week is a lot of money but we can slide the % to use less energy.

Before your power plant i paid 11000$/week,now 5600$.Thanks a lot The-multiverse

I am currently working on moddeling the Tjernobyl nuclear power plant so stay tuned i gues!

3000 MW Is actually fairly realistic for many designs, the 4 reactor Darlington Power Plant where I live in Ontario, Canada produces 3.1 Gigawatts (or 3100 MW) give or take depending on the demands on the plant. What I'd like to see is a nice big modern looking power plant like Darlington to place in one of my cities.

I think it would increase the realism if you require it to be place by water, not roadside. All nuclear power plants are near large bodies of water for cooling... :D

Should be noted that the actual electricity generating component isn't the reactor core, but turbine generators. The reactores are used as a heat producing element to super heat the liquid medium used to turn the turbines. So power output isn't nessisarilly a matter of cores, but a matter of turbine count and size.

2 core reactor with 1 turbine will produce less power than a 2 core reactor with 3 turbines of the same size.

as a matter of fact a 2 core nuclear power plant produces at best 4GWt that is 4 THERMICAL GW, however the actual electricity production is between 30-40% of that

Well it depends on the purpose. They are a lot testing Plants of course with less than 300MW, but a "modern" Plant has 1000 - 1400MW per Unit (Core). The next Generation (like EPR) is planned for 1700-1800MW.

Thanks for 300 Downloads :D

Thanks for 200 Downloads :D

600MW is not unrealistic for a nuclear powerplant. The largest nuclear power station in the world is the Kashiwakazi-kariwa plant in Japan. a 7 core plant that produces 8,000mw. That is the largest one in the world and it's considered on par with a wonder just by it's sheer size. Some indian NPS produce as little as 1,000MW with 6 cores. That means any core production between 166MW and 1080MW is completely realistic. The in game model is either one or two cores, so 600MW is totally reasonable either way anything between 200 and 2000 MW would be plausible for the in-game model. The campus size is surprisingly spot on as well for a two-stack nuclear station.
