Summary
The impurity radiation for typical tokamak parameters has been numerically calculated using an ''average-ion model.'' Coronal equilibrium values for the emission of oxygen, iron, molybdenum, tungsten and gold were determined from the steady-state solutions of a set of related rate equations which included the effects of electron collisional ionization and excitation, dielectronic and radiative recombination, ..delta..n = 0 and ..delta..n not equal to 0 line transitions, and bremsstrahlung. The results for oxygen and iron compare very well with other calculations. The detailed steady-state emission rates were used to investigate the effects of various concentrations of impurities on the n/sub e/tau requirements for breakeven, ignition, and Q = 5 beam driven reactor experiments.
