Abstract This review deals with the selection of electric propulsion system (EPS) for internationally developed and designed, primary nuclear-electric space tug International Nuclear Power Propulsion System (INPPS). INPPS is scheduled interplanetary missions to Mars Jupiter moon Europa by end decade 2020. Regarding specific technical mission parameters preselected thruster (ET) types, internati...

The open cycle Gas Core Nuclear Rocket (GCR) possesses, in principle, outstanding propulsion characteristics that make it especially attractive for advanced space propulsion. With uranium as fuel and hydrogen as propellant, it can generate several thousand seconds of specific impulse and hundreds of kilonewtons of thrust. In its standard configuration, however, GCR is susceptible to hydrodynami...

James Clay Moltz is Research Professor and Assistant Director of the Center for Nonproliferation Studies (CNS) at the Monterey Institute of International Studies. He also directs the Newly Independent States Nonproliferation Project at CNS. From 1993-98 (Vols. 1-5), Dr. Moltz was Editor of this journal. When the authors of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) crafted the...

Objectives: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

As we know that men have insatiable thirst in exploration and discovery especially to unfold the mysteries of universe. There are lots of frontiers that could be covered in space exploration but unfortunately, there are some reasons which affect it. Firstly, the distances to be covered are extremely large, this large distance in outer space makes it very difficult to prospect for an astronaut i...

This paper is a summary overview of a study conducted at the NASA Marshall Space Flight Center (NASAMSFC) during the initial phases of the Space Launch Initiative (SLI) program to evaluate a large number of technical problems associated with the design, development, test, evaluation and operation of several major liquid propellant rocket engine systems (i.e., SSME, Fastrac, J-2, F-I). One of th...

This paper discusses the variety of teaching methods employed by the Nuclear Department in the education and training of nuclear practioners in support of the United Kingdom’s Naval Nuclear Propulsion Programme (NNPP). Reactor physics is required to be taught at a variety of levels from introductory principles to postgraduate, a variety of teaching methods are employed to satisfy this requireme...
