"Over the years you have to pull the rods out higher and higher to expose more of the fuel because the fuel on the bottom of the core gets used up, or all these fission products are keeping it from reacting efficiently," Clark said.
Nuclear power plants on new submarines may last 40-plus years
(The French have recently cited this "plutonium mine" scenario as one of their primary motivations for continuing to reprocess.) The technical feasibility of plutonium recovery will indeed increase with time as the fission product radiation barrier decays away.
New nukes: the Bush administration's plan to use fuel reprocessing as the spark to revive nuclear power will not succeed. Only centralized interim waste storage can make a difference in the near term
Some proposals have been made to mitigate this issue, such as producing SiC fibres rather than monolithic SiC and embedding the fibres to form a composite, though this has the disadvantage of being permeable to fission products [21]; thus a combination of monolithic and composite SiC would be needed for fission product retention.
Assessment of Neutronic Characteristics of Accident-Tolerant Fuel and Claddings for CANDU Reactors
The fission products dissolve in the salt and are removed continuously in an online reprocessing plant and replaced with new fuel or fertile material.
Flatpack reactors
In conventional reprocessing, uranium and plutonium are separated from the fission products and other actinides in the spent fuel.
CANDU reactors and advanced fuel cycles
The PWRs encompass more than two-thirds of operating light-water reactors worldwide and have one to two orders of magnitude of coolant and steam generation fission product inventory compared to other reactors.
Numerical Simulation of Decontamination of Airborne Fission Products during In-Vessel Release Phase by Containment Spray
Even if it were, the anti-nuclear activist, Sheldon Novick wrote of fission products in his book, The Electric War, "it is difficult to see in what way they are any more or less hazardous than other poisons produced by industry."
Facts & fission: a veteran of the Manhattan Project argues for the real-world practicality of nuclear power
MELCOR can simulate various SA phenomena such as thermal-hydraulic response of the primary RCS, core uncovering, fuel heat-up, cladding oxidation, heat-up of the reactor pressure vessel (RPV) lower head by the molten core, lower plenum penetration, hydrogen production, and fission product release.

One of the important safety features of the HTGR is the robust fission product retention capabilities of the fuel elements [1].

The fission product emitted to the gas creates about L[E.sup.5] to 1[E.sup.6] electron-ion pairs along its path [10].
Neutron Flux Monitoring Based on Blind Source Separation Algorithms in Moroccan TRIGA MARK II Reactor
This should be based on the results of the research and implementation of defence-in-depth in the design of SMRs, including small power, smaller source term, increased safety margin, enhanced engineered safety system, smaller fission product release, and consequent reduced potential for radiation exposure to population in the vicinity of the plant;
