Not yet viable.
Perhaps some assumptions are being made about what speculative capital might be required to make said technology viable?
Maybe one of the reasons Small Modular Reactors are still not viable is because investment in wind and solar is much cheaper and is not nearly so speculative. Wind and solar doesn't solve the storage problem, but V2G also has a lot of potential as a future storage technology. Most of the internal combustion vehicles on the road today will have been replaced by 2050. If they have been replaced with V2G capable EVs, storage will simply not be an issue by then.
