Nuclear Propulsion Project Workshop summary

NASA-Lewis has undertaken the planning and coordination of a joint NASA/DOE/DOD Nuclear Propulsion Project which will investigate both nuclear electric and nuclear thermal concepts. The three-agency team has been tasked with the development of an Interagency Agreement and Memorandum of Understanding, as well as the drafting of a statement as to astronaut crew guidelines and values, the assessment of human-rating requirements, the development of an interagency safety and environmental assessment plan, and the development of test facility requirements. Attention is to be given to the role of SP-100 for nuclear-electric propulsion applications.

A comparison of Nuclear Thermal Propulsion concepts - Results of a workshop

A Nuclear Thermal Propulsion Workshop, co-sponsored by NASA, DOE and DOD, was held in Cleveland, Ohio on July 10-12, 1990. The workshop was to provide a database of nuclear propulsion concepts and technologies to assist in planning a nuclear propulsion project, identify high priority activities to be initiated early, and to provide cost and schedule estimates for development of concepts to technology readiness level 6 - full system verification in a simulated environment. Sixteen concepts were presented to Technology Review Panels (TRP), and discussed. Each concept was compared to a baseline manned Mars mission. A preliminary comparison of ratings made by the TRP's is presented herein for mission benefit, safety, technical risk, and development cost.
