2017 | AFC ACCOMPLISHMENTS 43 exposure in the AdvancedTest Reactor (ATR) and Halden reactor (Institute for EnergyTechnology) starting in 2018. CeramicTubular Products has developed a continuous process for doing chemical vapor deposition of SiC on the surface of SiC composite windings. UnitedTechnologies Research Center has been exploring methods for making composites utilizing SiC particles and SiC pre- polymer compounds to replace the CVI process. Two, 6-inch U3Si2 fueled rodlets (Figure 3) produced by INL have been removed from the ATR after achieving burnups of ~20 MWd/kgU. Swelling was 0% +/- 1% and fission gas release was
