We present the basic notions of the “Supercritical Pile” model of Gamma Ray Bursts (GRBs). This model is motivated by the need for a process that provides the dissipation necessary in GRBs and presents a well defined scheme for converting the energy stored in the relativistic protons of the Relativistic Blast Waves (RBW) associated with GRB into radiation; at the same time it leads to spectra which exhibit a peak in the burst νF_ν distribution at an energy E_p mg src=""http://www.sciencedirect.com/scidirimg/entities/2243.gif"" alt=""similar, equals"" border=0> 1 MeV in the observer’s frame, in agreement with observation and largely independent of the Lorentz factor Γ of the associated relativistic outflow.
