Radionuclide Absorption Demonstration System

Completed Technology Project

Project Introduction

Radionuclide Absorption Demonstration System
After a nuclear thermal rocket (NTR) is test fired, the engine’s reactor is operated in a cool-down mode during which radioactive exhaust by-products continue to be made, yet at a much lower rate. Extended operation of a Thermal Propulsion Capture System (TPCS) where all exhaust products are totally contained will be uneconomical during that longer term cool-down phase. Instead, a Regenerative Radionuclide Adsorption and Disposal System (RRAADS) could be implemented to trap radioactive emissions. This project built and tested a small scale demonstration system to verify that development of the technology is feasible. More »
