The ISS EEATCS radiator ORU Centaur co-generation experiment; A NASA SBIR 2015 proposal
The proposed decadal small fission reactor sadly is far in our future, so how to test the possibility of a small fission reactors radiators being used as a secondary power source? or a better question, how can this concept be used in non nuclear systems?
lets take the largest spacecraft radiator system now flying as an example, what if these radiators were incorporated into an empty in space stage tank filled with Xenon and with a stirling engine system? Or what if the ISS Ammonia system replaced the role of the Xenon? would Ammonia do damage to the Centaur fuel tank? would Ammonia damage the stirling engine?.
Not having radiators geometry inside the fuel tank would be a weight savings Docking a centaur with ISS with fluid connections to the ISS The EEATCS radiator ORU system or better stated replacing the radiator with the Centaur might be a tall order and what would 70 kW per hour provide to a stirling engine? remaining waste heat after the stirling engines recovered energy radiate through the Centaur in space stage hull.
The NASA radiator paper,
The EEATCS radiator ORU is a direct flow, deployable and retractable radiator system with two independent cooling loops Two MBSU cold plates, each designed to remove 495 watts at 80 lbs/hr. Three DDCU cold plates are each designed to remove 694 watts at 125 lbs/hr. The EATCS is designed to provide 35 kW of heat rejection per loop for a total capability of 70 kW
