Lancaster, PA November 14, 2017 – Advanced Cooling Technologies (ACT), announced that it is continuing to develop technologies supporting the nuclear industry in the areas of thermal management and materials modeling. Through multiple R&D contracts over the last 7 years, ACT has developed numerous solutions for thermal management in high temperature environments relevant to nuclear fission power generation in space and terrestrial applications. These contracts were awarded from different government agencies including NASA and DOD (Air Force, Navy) through multiple SBIR/STTR/BAA programs. “These projects enable us to develop technologies for the challenging needs of thermal management for nuclear power generation in both conventional reactors as well as advanced reactor concepts for space applications” says Dr. Calin Tarau, Lead Engineer at ACT who led several development efforts in this portfolio. “We have been actively engaged in several initiatives of NASA and DOE Laboratories to advance these technologies for nuclear applications”.
Notable examples of relevant projects include:
- Advanced Stirling radioisotope generator (ASRG) Backup Cooling System (NASA)
- Long-lived Venus Lander Thermal Management (NASA)
- Lunar Regolith Reactor Thermal Management (NASA)
- High Temperature Alkali Metal Heat Pipes for Space & Planetary Power (NASA)
- Low-cost Radiator for Surface Fission Power (NASA)
- Titanium-Water Heat Pipe for Spacecraft Fission Power (NASA)
- Meshless Peridynamics Framework for Corrosion Fatigue Damage Prediction (Navy)
- Atomistically-informed Chemical Kinetics Modeling for Ablative Materials (Navy)
- Multi-physics tool for predicting fatigue crack propagation using Phase field models (Navy)
ACT has a rich history of developing several heat pipe based technologies, as well as advanced material modeling capabilities to address unique thermal management and predictive modeling needs. ACT personnel have contributed to development of:
- Alkali-metal heat pipes for nuclear applications
- Heat pipe power systems for spacecraft and planetary surface vehicles
- Thermal management of both hot end and cold ends of the heat transfer system
- Thermal control devices
- Variable conductance thermal links
- Material models for microstructural evolution under irradiation
- Physics-based meshless modeling tools for corrosion crack propagation
- Multiphysics modeling tools for materials under extreme conditions
- System level models for thermal-hydraulics and design evaluation.
According to Dr. Srujan Rokkam, a Lead Engineer with background in nuclear materials science “These technologies and past experiences provides us with a unique bag of tricks to tackle the challenges and gaps necessary to be mitigated for design, evaluation and development of next generation (Gen IV) advanced nuclear reactor concepts”. “While ACT’s heat transfer devices can enable unique energy conversion concepts, the material modeling capabilities can be applied to gain predictive insights into the thermo-mechanical response of nuclear materials, as well materials chemistry at multiple interfaces and in radiation environments”. Understanding both thermal hydraulics and material behavior in nuclear environment provides us with a unique capabilities for emerging reactor designs and their development.
ACT is looking forward to the opportunities to further advance and develop the aforementioned technologies for nuclear application, through collaboration with NASA, DOE national laboratories, universities and commercial industrial partners.
