Design requirement for dual air supplies to melter borescope

Description: The long term survivability and usefulness of the melter surface viewing borescopes would be greatly increased if a method of remote lense cleaning was available. The two units to be installed on the DWPF melter will incorporate air cooling and lense purging into their design. At present a single air supply line would serve both needs. Separating the two air services will allow the introduction of water or steam into the purge service. Tests on the prototype borescope at ETF have shown this to … more
