Abstract

A method of preventing deposition of material inside a fusion chamber includes a step of determining a range of oxygen to carbon ratios where substantially no carbon solids or lead oxides are formed, the range depending upon temperature and hydrogen content of the chamber. Then a step is performed of adding oxygen to the chamber to form carbon monoxide. Next, additional oxygen can be added to the chamber to consume hydrogen in the chamber to form water, and reduce the tritium partial pressure, in addition to forming carbon monoxide. Concentration of additional oxygen levels is limited to levels to preclude lead oxide formation.
