[2I07] Development of Security and Safety Fuel for Pu-burner HTGR
(13)Test and characterization for ZrC coating
Keywords:Coated fuel particle, Zirconium carbide, ZrC, Chemical vapor deposition, Coating test, Characterization
To extend burnup of security and safety fuel for Pu-burner HTGR, zirconium carbide (ZrC) acting as an oxygen getter is coated directly on the inert matrix fuel kernel. In the fiscal year 2015, ZrC coating test on YSZ dummy kernel by bromide process has been started, and ZrC layer with 14 μm of thickness has been obtained successfully at 1350 0C of deposition temperature with 100 g of particle loading weight. Relationship between material properties and coating conditions on ZrC such as temperature, etc. are examined through upcoming ZrC coating tests.
