Why's that? What were we promised? I'd say the wet scrubbers, wet flue gas desulfurization units, and IGCC configurations do a pretty damn good job.
As for the lack of emission from a nuclear power plant, that shouldn't come as a big surprise. Nuclear power releases no solids into the atmosphere. Recirculating water doesn't come in contact with the reactor vessels, and any exhaust or vented gas that is radioactive is stored and compressed until the radioactivity level is deemed acceptable for release to the atmosphere. Air ejector exhausts on modern units have no radiation exposure unless you have leaking boiler tubes. Boiling Water Reactors do have radioactive exhaust that is filtered by charcoal systems, but those are pretty much obsolete. Honestly, most of your nuclear emissions come from the exhaust of backup diesel generators.
