Effluent Scrubbing of Engine Exhaust of a Nuclear Thermal Propulsion Engine Project

Completed TRL 2 (started at 1, targeting 2)

Description

The Institute for Clean Energy Technology (ICET) at MSU already supports long-standing high-efficiency nuclear particulate air (HEPA) filtration research as well as other related research. This project will explore nuclear effluent scrubbing to support Nuclear Thermal Propulsion (NTP). The project will evaluate NTP engine exhaust scrubbing requirements and define corresponding filter and scrubbing system size requirements for selecting filter material, operating temperature range, static and trans-filter pressure differential maximum/minimum, and associated effluent flow rate. The project will provide technical assistance in establishing facility requirements; i.e., pre & post-test safety, filter inspection and hazard mitigation. Scrubber system operational constraints with selected filter technologies, post-test/operations, facility safety, filter replacement disposal requirements, and facility cost estimates will be better developed at the project's conclusion. The goal was to advance the technical immaturity of the direct gas treatment (effluent scrubbing) approach; and to investigate filtering feasibility and identify design requirements. The scope of this effort includes the following: (1) identify and research the latest technologies available for radioactive effluent scrubbing that would work on the magnitude required for testing an NTP engine and stage vehicle development (i.e., up to 30 lbs/sec hydrogen flow rate for 1 hour duration) and (2) scope and estimate costs required for work and effort necessary to develop a hydrogen scrubber system to support NASA's NTP engine and stage development anticipated goals.

Benefits

Benefits to the nation would include providing technologies to enable repeatable and efficient method for establishing an environmentally safe manner for testing and utilizing NT related technologies (nuclear power plants, research reactors, etc.), because future powering capabilities may evolve towards a more global use of nuclear power reactors, since they do not emit the gases that contribute to global warming, acid rain, or urban smog.

How to get involved

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
