TL;DR: In this paper, an automotive or other power system including a flow cell, in which the stack that provides power is readily isolated from the storage vessels holding the cathode and anode slurry (alternatively called fuel) is described.
Abstract: An automotive or other power system including a flow cell, in which the stack that provides power is readily isolated from the storage vessels holding the cathode slurry and anode slurry (alternatively called “fuel”) is described. A method of use is also provided, in which the “fuel” tanks are removable and are separately charged in a charging station, and the charged fuel, plus tanks, are placed back in the vehicle or other power system, allowing fast refueling. The technology also provides a charging system in which discharged fuel is charged. The charged fuel can be placed into storage tanks at the power source or returned to the vehicle. In some embodiments, the charged fuel in the storage tanks can be used at a later date. The charged fuel can be transported or stored for use in a different place or time.

TL;DR: In order to prevent the spent fuel from going critical, the fuel assemblies are partitioned off from each other in metal boxes whose walls contain neutron-absorbing boron.
Abstract: Because of the unavailability of off-site storage for spent power-reactor fuel, the NRC has allowed high-density storage of spent fuel in pools originally designed to hold much smaller inventories. As a result, virtually all U.S. spent-fuel pools have been re-racked to hold spent-fuel assemblies at densities that approach those in reactor cores. In order to prevent the spent fuel from going critical, the fuel assemblies are partitioned off from each other in metal boxes whose walls contain neutron-absorbing boron. It has been known for more than two decades that, in case of a loss of water in the pool, convective air cooling would be relatively ineffective in such a "dense-packed" pool. Spent fuel recently discharged from a reactor could heat up relatively rapidly to temperatures at which the zircaloy fuel cladding could catch fire and the fuel's volatile fission products, including 30-year half-life 137 Cs, would be released. The fire could well spread to older spent fuel. The long-term land-contaminatio...

TL;DR: In this paper, the Radkowsky Thorium Reactor (RTR) concept has been applied to a Russian design of a 1,000 MWe pressurized water reactor, known as a WER-1000, and designated as WERT.
Abstract: The proliferation potential of the light water reactor fuel cycle may be significantly reduced by utilization of thorium as a fertile component of the nuclear fuel. The main challenge of thorium utilization is to design a core and a fuel cycle, which would be proliferation‐resistant and economically feasible. This challenge is met by the Radkowsky Thorium Reactor (RTR) concept presented in this paper. So far the concept has been applied to a Russian design of a 1,000 MWe pressurized water reactor, known as a WER‐1000, and designated as WERT. The following are the main results of the preliminary reference design: The amount of plutonium contained in the RTR spent fuel stockpile is reduced by 80 percent in comparison with a WER of a current design. The isotopic composition of the RTR‐Pu greatly increases the probability of preini‐tiation and yield degradation of a nuclear explosion. An extremely large Pu‐238 content causes correspondingly large heat emission, which would complicate the design of an explosiv...
