“…For each of the lunar-based options, the mass for the nuclear surface reactors to provide the necessary power is the limiting factor. The HTGR produces 10 MW per reactor with a mass of 49.4 tons each [18]. The launchers are designed to be launched daily in order to take advantage of every launch window.…”

In the future, there will be a need for constant cargo launches from Earth to Mars in order to build, and then sustain, a Martian base. Currently, chemical rockets are used for space launches. These are expensive and heavy due to the amount of necessary propellant.Nuclear thermal rockets (NTRs) are the next step in rocket design. Another alternative is to create a launcher on the lunar surface that uses magnetic levitation to launch cargo to Mars in order to minimize the amount of necessary propellant per mission. This paper investigates using nuclear power for six different cargo launching alternatives, as well as the orbital mechanics involved in launching cargo to a Martian base from the moon. Each alternative is compared to the other alternative launchers, as well as compared to using an NTR instead. This comparison is done on the basis of mass that must be shipped from Earth, the amount of necessary propellant, and the number of equivalent NTR launches. Of the options, a lunar coil launcher had a ship mass that is 12.7% less than the next best option and 17 NTR equivalent launches, making it the best of the presented six options.

“…Having established that Closed Cycle Gas turbine power plants with both directly or indirectly supplied thermal energy from nuclear heat sources would best meet the NGNPP-Gen IV power plant requirements, an author generated CBC code previously used in the modeling of space and planetary surface power systems (Juhasz 2005(Juhasz , 2006(Juhasz , 2007 was modified to meet the modeling requirements of terrestrial nuclear power plants. Special emphasis was placed on incorporating the two series heat exchanger requirements of LFTR-reactors as exemplified by ORNL MSRE technology.…”

An overall system analysis approach is used to propose potential conceptual designs of advanced terrestrial nuclear power plants based on Oak Ridge National Laboratory (ORNL) Molten Salt Reactor (XISR) experience and utilizing Closed Cycle Gas Turbine (CCGT) thermal-to-electric energy conversion technology. In particular conceptual designs for an advanced 1 GWe power plant with turbine reheat and compressor intercooling at a 950 K turbine inlet temperature (TIT), as well as near term 100 1VIWe demonstration plants with TITS of 950 K and 1200 K are presented. Power plant performance data were obtained for TITS ranging from 650 to 1300 K by use of a Closed Brayton Cycle (CB(:') systems code which considered the interaction between major sub -systems, including the Liquid Fluoride Thorium Reactor (LFTR), heat source and heat sink heat exchangers, turbo -generator machinery, and an electric power generation and transmission system. Optional off-shore submarine installation of the power plant is a major consideration.
