You're just making that up, you know. Nuclear has been given such horrible handicaps as 100% loan guarantees. Oh the burden they operate under!
A lot of countries, such as here in Sweden, have a separate nuclear power tax, and a large thermal power tax. Oil and coal, for example, only pay the latter here. These are in addition to the nuclear waste management fees. Nuclear power is the only power source that pays for proper waste disposal (coal, oil and gas just spews it into the atmosphere and wind power installations are simply buried after they expire).
So no, I'm not making it up. Nuclear power is heavily taxed which is the largest reason why it's suddenly turned uneconomical in the last decade.
Over here, renewables are most heavily subsidised through elcertifikat[1], which is basically a tax per kWh on electricity brokers, given to producers of renewable energy. This cost is then passed on to the consumer. However, it's not a straight tax and it's a bit complicated, but a renewable source gets on average around 40% extra on top of the sale price[2]. We don't build new hydro power plants, and our climate isn't very suitable for large scale solar, so "building renewable energy" here basically means building a lot of wind power.
Nuclear power is then levied additional tax on top of this, which was raised quite substantially a few years ago by the Greens when in government. Note the nuclear waste disposal fee is separate to this tax.
Traditionally, our energy mix has been about 50/50 nuclear and hydro power, and some wind and others thrown in. Wind power is now increasing[3]. Nuclear power has historically been very profitable for us and our electricity prices have been very low by international standards, but there's an ongoing phase-out for wind power and the cost of electricity is steadily increasing.
That should give you some insight how and why renewables are heavily subsidied here and nuclear power heavily taxed. I'm sorry sources are in Swedish, a lot of the data seems to be unavailable in English.
