His arguments are propaganda, pure and simple. You endorse his "numbers", but make no mention of the way those numbers fit into a a larger set of equally relevant information that invalidates the significance he assigns his data. For example, using
HIS fundamental criteria for selecting an energy source going forward we should continue to burn fossil fuels.
His ONLY numerical argument for nuclear is that nuclear has produced more electricity than other competing technologies.
He refuses to consider external costs for nuclear, so why should we consider them for fossil fuels?
He refuses to consider the political support that led to the favorable numbers of nuclear, so why should we consider that about coal and demonize the coal lobby?
If the ONLY valid yardstick is aggregate numbers of kWh produced to date, the we should shut down the nuclear plants and increase natural gas and coal generation forever.
Of course that is a ridiculous argument for continuing to use coal, isn't it? It is no less ridiculous when applied to nuclear and the POTENTIAL problems associated it.
The rhetorical sleight-of-hand practiced by Nnadir is to, on a limited basis, compare the crisis created by overuse of fossil fuels to the fact that nuclear isn't a heavy producer of GHG emissions while omitting production numbers - with no mention of production or costs. He then compares the cost and production numbers of nuclear with the cost and production numbers of renewables - with no mention of externalities. That's simply dishonest.
Since this discussion has started the cost figures for nuclear have skyrocketed, so that aspect of nuclear is no longer a reason to support it. When the known/potential externalities and other relevant considerations are factored in to the equation determining what technologies we should pursue to address climate change, the results of the equation are significantly different than Nnadir's "numbers" provide.

Review of solutions to global warming, air pollution, and energy securityMark Z. Jacobson
This paper reviews and ranks major proposed energy-related solutions to global warming, air pollution mortality, and energy security while considering other impacts of the proposed solutions, such as on water supply, land use, wildlife, resource availability, thermal pollution, water chemical pollution, nuclear proliferation, and undernutrition.
Nine electric power sources and two liquid fuel options are considered. The electricity sources include solar-photovoltaics (PV), concentrated solar power (CSP), wind, geothermal, hydroelectric, wave, tidal, nuclear, and coal with carbon capture and storage (CCS) technology. The liquid fuel options include corn-ethanol (E85) and cellulosic-E85. To place the electric and liquid fuel sources on an equal footing, we examine their comparative abilities to address the problems mentioned by powering new-technology vehicles, including battery-electric vehicles (BEVs), hydrogen fuel cell vehicles (HFCVs), and flex-fuel vehicles run on E85.
Twelve combinations of energy source-vehicle type are considered. Upon ranking and weighting each combination with respect to each of 11 impact categories, four clear divisions of ranking, or tiers, emerge.
Tier 1 (highest-ranked) includes wind-BEVs and wind-HFCVs.
Tier 2 includes CSP-BEVs, geothermal-BEVs, PV-BEVs, tidal-BEVs, and wave-BEVs.
Tier 3 includes hydro-BEVs, nuclear-BEVs, and CCS-BEVs.
Tier 4 includes corn- and cellulosic-E85.
Wind-BEVs ranked first in seven out of 11 categories, including the two most important, mortality and climate damage reduction. Although HFCVs are much less efficient than BEVs, wind-HFCVs are still very clean and were ranked second among all combinations.
Tier 2 options provide significant benefits and are recommended.
Tier 3 options are less desirable. However, hydroelectricity, which was ranked ahead of coal-CCS and nuclear with respect to climate and health, is an excellent load balancer, thus recommended.
The Tier 4 combinations (cellulosic- and corn-E85) were ranked lowest overall and with respect to climate, air pollution, land use, wildlife damage, and chemical waste. Cellulosic-E85 ranked lower than corn-E85 overall, primarily due to its potentially larger land footprint based on new data and its higher upstream air pollution emissions than corn-E85.
Whereas cellulosic-E85 may cause the greatest average human mortality, nuclear-BEVs cause the greatest upper-limit mortality risk due to the expansion of plutonium separation and uranium enrichment in nuclear energy facilities worldwide. Wind-BEVs and CSP-BEVs cause the least mortality.
The footprint area of wind-BEVs is 2–6 orders of magnitude less than that of any other option. Because of their low footprint and pollution, wind-BEVs cause the least wildlife loss.
The largest consumer of water is corn-E85. The smallest are wind-, tidal-, and wave-BEVs.
The US could theoretically replace all 2007 onroad vehicles with BEVs powered by 73000–144000 5 MW wind turbines, less than the 300000 airplanes the US produced during World War II, reducing US CO2 by 32.5–32.7% and nearly eliminating 15000/yr vehicle-related air pollution deaths in 2020.
In sum, use of wind, CSP, geothermal, tidal, PV, wave, and hydro to provide electricity for BEVs and HFCVs and, by extension, electricity for the residential, industrial, and commercial sectors, will result in the most benefit among the options considered. The combination of these technologies should be advanced as a solution to global warming, air pollution, and energy security. Coal-CCS and nuclear offer less benefit thus represent an opportunity cost loss, and the biofuel options provide no certain benefit and the greatest negative impacts.
