The hurdles for nuclear power are many, from designs to the permit process. There are a couple of problems that still need to be addressed and those are a long term disposal facility and the decommisioning of old reactors.
The current storage of spent fuel and waste has not changed; the Yucca mountain storage facility had problems both physical and political. There are very few alternative storage solutions beyond storing in the cooling tanks.
Decommissioning a reactor takes a lot more time and expense than given when the reactor facility is proposed. Decommissioning a reactor is similar in concept to cleaning up asbestos contaminated buildings, both use stringent methods to contain the mess and also deal with the collected wastes. Decommissioning a reactor can take as long as a decade with similar problems with dealing with the radioactive wastes.
The alternate nuclear technology may help get all of us through the end of the era of cheap oil. But, there needs to be a good answer to waste disposal and decommissioning.
