Abstract—A detailed analysis of interdiffusion processes in emitter shells of electrogenerating channels (EGC) of reactors for space application after long term reactor irradiation is performed. Interdiffusion of Mo and W in the mono- and polycrystalline manufacturing technology with the W layer applied over them with thickness on the order of 10–4 m with irradiation time from 3000 to 12 350 h and at temperatures from 1350 to 1670°C is studied. One of the mechanisms which facilitate the pore-formation process in the W layer and its separation is demonstrated. A method of calculating the activation energy, temperature, and residual thickness of the W layer on the basis of which the state of the shells can be estimated for a long time from the start of irradiation is proposed.
