Three scenarios representing significant levels of containment loss due to moderate, substantial, and major damage to the 102 Building at the Vallecitos Nuclear Center are postulated, and the potential radiation doses to the general population as a result of the airborne releases of radionuclides (hereafter called source terms) are estimated. The damage scenarios are not correlated to any specific level of seismic activity. The three scenarios are: 1. Moderate damage scenario-perforation of the enclosures in and the structure comprising the Plutonium Analytical Laboratory.
