“…Er as BA is considered for weapon-grade plutonium fuel pebbles of high temperature reactor (HTR) (Kodochigov et al, 2003) and for mixed oxide (MOX) fuel in graphite RBMK reactors (Balygin et al, 1999), where other materials were studied (Er, Gd, Hf and Lu). The US study (Talamo et al, 2009) of the QUADRISO fuel particles for HTR contemplates BA based on Eu rather than Er in the earlier studies.…”

The paper describes the development, validation, and use of U W B 1 code intended for fast calculation of nuclear fuel depletion in burnable absorber research. The degree of effectiveness of burnable absorbers in the form of natural abundance elements, nuclides, and their combinations are compared on metric evaluating characteristic properties of burnable absorbers; namely the initial reactivity compensation, residual poisoning minimization, and the influence of the fuel reactivity for higher fuel burnups. The following materials suitable for burnable absorbers are recommended: Li, Pa, Ir, In and Re, as well as perspective of Li-6 enrichment; beside previously commonly studied boron and rare earth metals. The research results are intended for the application in other technical-economical analyses of the selection of added materials in the nuclear fuel for increasing the fuel efficiency and nuclear safety.

“…However, variants such as the QUADRISO concept have been suggested that incorporate an additional layer of burnable poison such as Eu 2 O 3. 108 Early attempts to fabricate spherical powder relied on mechanical grinding while later internal or external gelation processes were used to form spherical particles of the oxide fuel or porous particles that are then infiltrated by actinide nitrate solutions. ZrO 2 -based mixed oxide fuel and Np-mixed oxide fuel spheres have been produced by internal gelation in which an aqueous metal nitride solution is blended with hexamethylenetetramine (C 6 H 12 N 4 ) and urea.…”

Opportunities for Advanced Ceramics and Composites in the Nuclear Sector

Ceramics have played a crucial role in the development of fission based nuclear power, in glass & glass composite high level wasteforms, in composite cements to encapsulate intermediate level wastes (ILW) and also for oxide nuclear fuels based on UO2 and PuO2/UO2 mixed oxides. They are also used as porous filters with the ability to absorb radionuclides (RN) from air and liquids and are playing a key role in the cleanup at Fukushima. Non‐oxides also find current fission applications including in graphite moderators and B4C control rods. Ceramics will continue to be significant in the near‐term expansion of nuclear power via next‐step developments of fuels with inert matrices or based on thoria and in wasteforms using alternative composite cements or single or multiphase ceramics that can host Pu & other difficult RN. Longer term advances for Generation IV reactors, which will operate at higher temperatures & with higher fuel burn‐up require innovative fuel developments potentially via carbides & nitrides or composite fuel systems. Novel non‐thermal (cement‐like) and thermal techniques are currently being developed to treat some of the difficult legacy wastes. Non‐thermally derived wasteforms developed from geopolymers, composite cements, hydroceramics, and phosphate‐bonded ceramics and thermally derived wasteforms made by Hot Isostatic Pressing and fluidized bed steam reforming (FBSR) as well as vitrification techniques based on cold crucible melting (CCM), Joule‐heater in‐container melting and plasma melting (PM) are described. Future developments in waste treatment will be based on separation technologies for partitioning individual RN along with design & construction of RN‐containing ceramic targets for inducing transmutation reactions. Near demonstration actinide‐hosting ceramic wasteforms including multiphase Synroc systems are described. Opportunities also exist for ceramics in structural applications in Generation IV reactors such as composite SiC/SiC and C/C for fuel cladding and control rods and MAX phases and ultrahigh‐temperature ceramics (UHTCs) may find near core fuel coating and cladding applications. Uses of ceramics in fusion reactor systems will be both functional (ceramic superconductors in magnet systems for plasma control and in Li silicate breeder blankets in tokamaks) and structural including as sapphire diagnostic windows, graphite diverters, and plasma facing C and UHTCs. In all these cases, performance is limited by poorly understood radiation damage and interface controlled processes, which demands a combined modeling/experimental approach.

“…In the QUADRISO concept the poison can be mixed in any of the coating layers of ordinary TRISO particles or in the fuel kernel. 25 It is beyond the scope of the present study to select the optimum configuration taken into consideration the manufacture, the best thermo-mechanical, and the chemical performance issues. QUADRISO particles with a 10 μm layer of ZrC deposited next to the fuel kernel have been fabricated for reducing the pressure on the SiC layer by absorbing oxygen.…”
