This research report gives the effect of impurity radiation on the attainment of high beta and high temperature for an ohmic discharge in the case of a tokamak like HBT-EP. Time dependent, one dimensional transport calculations were done using the HERMES code. The permissible impurity influx from the wall was found to decrease with increase in the magnetic field. For attaining a plasma temperature around 100 eV with the value of {beta} close to the Troyon {beta} limit, the maximum magnetic field was found to be around 0.6 Tesla with a maximum permissible impurity influx of about 0.2% of the hydrogen ion flux reaching the wall. 7 refs., 8 figs.
