Paul Blejwas

PaulPaul seeks to design a viable nuclear reactor for space applications. MCNP6.1 (Monte Carlo N-Particle code) is being used to systematically evaluate a number of design factors. Simulations are given special care and designed to examine specific parts of potential reactors. Fuels and fuel mixtures, reactor geometry and size, possible moderators, and coolant channels are all items of interest; many of these items require collaboration from other areas of the project as well as from the existing nuclear industry. Through careful iteration and inspection we hope to move towards feasible reactor designs for space applications.

Michael Ishida

One of the power conversion systems that the group is considering for the project is a two-phase space Rankine system. I am working on the thermodynamic analyses of space Rankine systems, developing a cohesive Rankine model that takes user inputs for key thermodynamic values of the system and outputs performance metrics. I am in the process of validating the equations and analysis methods by attempting to recreate the results of existing published papers about other proposed space Rankine systems. If unable to recreate results within a certain tolerance for varying input data assumptions, the model and equations will need to be adjusted to be more accurate. The model will be adjusted to reflect the research done by others in the group on different components of the system. Once that is complete, I will create a design for the possible Rankine system (picking a working fluid, operating temperature, radiator size, etc.) given the given mission constraints; the performance estimates of this optimal Rankine system will be compared to the performance estimates of other systems.

Ryan Moriarty

Ryan’s research is centered around the analysis of thermodynamic systems on nuclear powered spacecraft using an electric propulsion system. Such electric spacecraft are important to the future of space exploration as they are more efficient than chemical powered rockets. Therefore, the development of systems which can efficiently convert the thermal power into electric power a key step in furthering our exploration abilities.

Dana Stevens

Dana’s research focuses on radiators and heat exchangers for spacecraft with electric engines and nuclear power. In order to be efficient the space craft needs to have a good power to weight ratio. The heavier the spacecraft is, the more expensive it would be to send it into space. One aspect of the research is figuring out the best thermodynamic system for powering the spacecraft. The role that I will be playing is looking into the radiator in the thermodynamic system. The radiator needs to work efficiently at dispelling heat. Another requirement is that the radiator is light enough to send into space. We will be looking at the specific power of the radiator.

Kyle V. Neumann

Kyle V Neumann
Kyle earned a Bachelors of Science in nuclear engineering at Rensselaer Polytechnic Institute in December of 2016. During the summer of 2015 Kyle examined the Doppler Broadening utility and the burn-up functions of MCNP6, which will be used in future research into advanced reactor concepts. Currently he is examining the effects of radiation on the solubility of dissolved salts in nuclear waste stored at the Hanford and Savannah River sites. In addition to the solubility of particles in the waste, Kyle is examining the effects the multiphase composition of the waste has on the dissolution rate of each mineral particle phase in the waste tanks.
