What is it about?
Terrestrial Gamma-ray Flashes is a magnificent phenomenon in the Earth’s atmosphere which still does not have non contradictory and complete explanation. In this article a new model is proposed. In this model relativistic runaway electron avalanches are boosted by gamma-ray exchange between different regions of the thundercloud.

Why is it important?
Further investigation of relativistic runaway electron avalanches may not only lead to understanding of TGFs, but also may give an insight into the problem of lightning initiation.
Perspectives
In this article the most simplified case of reactor-like processes in a thundercloud is considered: critical electric field direction is random for different parts of the thundercloud. Further investigation of the reactor model requires consideration of more realistic electric fields. Moreover, reactor model has observable features which must be confirmed or disproved with existing TGF experimental databases.
