DEVELOPMENT OF BARIUM OXIDE-URANIUM OXIDE-TUNGSTEN EMITTERS FOR USE IN NUCLEAR HEATED THERMIONIC CONVERTERS

This developmental program was directed toward the fabrication, operation and testing of unclad nuclear heated thermionic emitters that can be operated in the 1100-1300 C temperature range with an expected current density capability of 1 - 10 amps/sq cm. Electron emitters containing various concentr...

Beschreibung
Zusammenfassung:	This developmental program was directed toward the fabrication, operation and testing of unclad nuclear heated thermionic emitters that can be operated in the 1100-1300 C temperature range with an expected current density capability of 1 - 10 amps/sq cm. Electron emitters containing various concentrations of BaO and UO2 dispersed in tungsten were tested both in the laboratory and in a nuclear reactor. The nuclear reactor data, because of its classification status, are published as a separate report entitled ''Development of Barium Oxide - Uranium Oxide Tungsten Emitters for use in Nuclear Heated Thermionic Converters - Part II''.
