Increasing space-nuclear-reactor (SNR) power requirements force system weights - and temperatures - upward. For such growth thermionic energy conversion (TEC) excels in SNR service between tenths of a megawatt and about ten megawatts. But TEC yields much current at low voltage. And as total outputs soar, radiators at 400 K for conventional power conditioning (PC) balloon compared with those at 1000 K and higher for TEC itself. To reduce PC problems TEC requires contiguous high-temperature inversion or internal electromagnetic-wave generation. Both are possible, potentially practical and probably exploitable through research. However attaining suitable efficiencies with these different operating modes and higher rejection temperatures demands new electrode and additive technologies as well as decreased cesium pressures and increased TEC temperatures. Furthermore such thermal growth necessitates alloys that approach ultimate metal capabilities for space applications.
