The waste product is salt has to be disposed.
Sell the salt? No, that would have been the solution to the Salton Sea fiasco which has no solution.
—————
Use the salt on the roads in winter or sell it to the many places that do.

For landfills in the desert, take the salt and add it to layers of garbage the salt keeps the microbes from decomposing the garbage and releasing methane or co2 for tens of thousands if not millions of years.
You could also landfill biomass,like brush, agricultural wastes or forest thinnings this also would sequester all that carbon for millions of years if you are into that kinda thing. This would actually work and be cheap too. Much cheaper than injecting liquid co2 into the earth for sequestration. Dr evil aka Bill Gates is planning on using the salt landfill , trees route it is one of the few ways to actually keep megaton amounts of carbon out of the carbon cycle for geological time scales.
Here is a better idea for all that sodium chloride...

Grid scale power storage right next to the nuke no special geology needed for compressed air or hydro storage, also no need to throttle your nuke run that baby flat out.
Oh once you have huge tanks of NaOH and HCl you can do interesting things with very low cost acid and bases in massive amount on tap.
NaOH when mixed with water and air is blown across it has a nice habit of forming Sodium bicarbonate with the co2in the air supplying the carbonate ion. Bicarb has a number of valuable uses and could be sold as is. Bicarb can also be put into a electrolysis cell and DC current run through it...you get back your NaOH and co2 gas comes out at high purity. Did we just do direct air capture on the cheap with nuclear power yes we did. Co2 plus water plus elections from said nuke gets you to all manner of chemicals via electrocells. Ethanol,propane,butane,methane,acetone,isopropyl to name a few all with over 90% faraday eff that means 90% of your energy ended up in the desired products.
Those same cells can also make formate or acetate from co2 and water. Those two are biologics single cell microbes eat them and can be programmed to make , sugars,lipids,oils,starches, and proteins we commonly call that food or feed. On scales of millions of tonnes per year per reactor they would be one a per acre basis a million times more feed or food per acre. You literally can make Kcals from thin air , water and nuclear electrons.
NaOH also can be used to extract proteins from leaf matter and plant stalks as Leaf protein concentrate, having cheap sodium hydroxide opens billions of tonnes of waste biomass to protein concentrate extraction think , chicken and hog feed on a scale that changes the feed industry forever.
HCl acid is the best acid to use for hydrolysis of biomass to sugars, right after your done sucking all the protein out of that biomass you hit it with dilute acid and turn the 50% of the dry mass of hemicellulose into 5 carbon sugars drain those off and feed them to yeast for hooch or E85 with sub 5 cents per lb sugar costs. Cheap acid = cheap sugars. Yeast also turn pentose into high quality proteins again feed that too humans or livestock as a byproduct.
Now you have cellulose and lignin left hit it with strong acid which will become the dilute acid for the first step and you turn cellulose into it’s 6 carbon base units of glucose. Glucose being the universal energy sugar in the biological world, humans literally live off it in our bloodstream everything we eat eventually gets turned into glucose to fuel us, same for every other mammal. Once you have glucose you can feed anything, or use microbes to make any biological chemical there is. No other chemical is more versatile than glucose in the bioworld, the most wasteful thing to do is feed it to yeast and make ethanol but ok let’s do that because Congress loves bug agri. Same same the left over yeast is prime complete protein too.
You have lignin left its nature’s largest source of aromatic rings , it also is what coal is made from once buried. Speed up the process with heat and pressure to crack those rings and you get aromatic hydrocarbons in the jet fuel range aka actual jet fuel, you need high purity llignin to do this step and if you acid treat wood,straw,hay,hemp, or any other grass stems which all grains are grasses you get chemical grade lignin after you remove the Hemi/cellulose sugars from it.
So having those flow batteries with acid base tanks is really a huge source of cheap acids and bases the cost is the electricity not sold by turning them back into salt water. By default if you have an economic flow membrane and battery you already have an acid base making machine on a huge scale.
