Nuclear fuel provided with a coating

摘要

This invention relates to a method of preparing a nuclear fuel including the step of depositing a coating which includes fluorine, or at least one compound thereof, around a kernel (12) of fissile material. The invention extends to a coated nuclear fuel particle (10).

主权项

1. A method of preparing a nuclear fuel, which method includes:
depositing a mixture of silicon and silicon carbide around a kernel of fissile material by chemical vapour deposition in a fluidised bed deposition chamber of a chemical vapour deposition reactor from a chemical vapour deposition source gas comprising methylchlorosilane which is fed to the deposition chamber, and fluorinating the silicon and silicon carbide with fluorine gas by adding the fluorine gas to the methylchlorosilane which is fed to the deposition chamber.
