Easily outweighed by the savings in emissions over the lifetime of the plant. Generation 3 and 3 "Advanced" reactors already generate significantly less waste than the Gen2 reactors that make up the majority in operation. Generation 4 reactors are in the design phase (some with proven technology, others with technology that is scientifically sound in theory but need some additional advances made) that reduce it by even larger amounts. Even Gen2 reactors with all their faults over their lifetime are a huge net win over coal and gas fired power plants. Producing photovoltaic panels generates tons of waste, as well, much of it quite toxic to humans and generally bad for the environment. Even building wind turbines isn't a perfectly clean task. Our primary problem at this point is carbon emissions. Nuclear is a very viable option for significantly reducing them even at current technology levels, and with huge strides on the way.
