Waste? There is very little high level waste. The toxicity of the rest is very low - but people are paranoid about radiation compared to equivalent risks from all sorts of things.
Bad engineering? That's why you use a standard design. Three Mile Island did not hurt anyone. It was a financial disaster.
Do you think that solar and wind don't have related problems. Try disposing of solar panels - much more toxicity per lifetime kWh than nuclear waste (excluding the high level, but very low volume nuclear waste). And, we export a lot of the solar toxicity that advocates don't see. China builds them, and they have little care for the environment, and produce vast amounts of toxic waste. Ditto - again China - with the waste involved in refining the rare earths needed by wind farms and especially electric cars.
But you ignore the true problem: solar and wind cannot deliver reliable power, with a few exceptions. I'm sorry you skipped over that in reading my comment. Storage technologies so far are a joke for this purpose. The cost per kWh stored is enormous, especially when you have to have enough storage to handle extended outages of wind and solar. And, most battery storage technologies proposed are produced with a lot of toxic waste, and contain a large amount of toxins, and they have to be periodically replaced.
As an engineer, I am shocked that anyone would attack nuclear, given its very few failures per kWh produced, and the relatively low environmental and human harm from those failures, when amortized across the whole fleet of nuclear plants. And... those plants are mostly old designs - done before we had good CAD/CAM and before we had good physics simulators. Newer designs can be far better, some are inherently safe from meltdowns, even - i.e. passively safe, no active systems required.
So, engineer, look at the whole system. The system reliability and the economic costs of lowered reliability, the environmental impact (including the vast amounts of land now covered with 300' high wind turbines, or huge solar farms). Look at the human costs of these if you actually do the engineering and resulting construction necessary to have the level of reliable power needed by any modern society.
