We calculate the light element production induced by the explosion of an isolated supernova in the ISM. We use a time-dependent model and consider energetic particles accelerated at the forward (process 1) and reverse (process 2) shocks. Both processes are primary, but are shown to underproduce Be and B in the early Galaxy. The reasons for this failure are analyzed and used to determine what basic characteristics a model should involve in order to be successful. Quite remarkably, we find that these requirements seem to converge toward a model involving superbubbles as the site of particle acceleration out of a metal-rich material. Such a model is presented in the accompanying paper OG.3.2.51.
