A sodium filled heat pipe was tested in a magnetic field of up to 1 Tesla. An analysis of the heat pipe operation is given. The MHD pressure drop is calculated as a function of the Hartmann number, which includes effects of the magnetic field strength and a characteristic flow area dimension parallel to the lines of magnetic flux. Some vacuum outgassing and atomic hydrogen and helium sticking probability measurements are given for graphite fibers. (MOW)
