E-MAIL: Click here to contact the contract specialist via, daniel.bertuna@dtra.mil. The Defense Threat Reduction Agency has a requirement to update the Peyton-Byrne model or to develop a new model to account for existing weapons, with their various yield options. Further, models need to be developed to account for the radiation transport through RV/RB cases and carriers when weapons are detonated a various altitudes. Detailed ground motion and cratering calculations and simple engineering prediction models of ground motion for nuclear weapon surface burst explosions are based on a series of well defined, early time coupling calculations completed during the mid 80's to the early 90's. All but two of these calculations assumed a Reentry Vehicle (RV) or Reentry Body (RB) mounted warhead exploding on contact or in near proximity to the earth's surface. Only two of these earlier calculations were based on laydown bomb calculations. The coupling results from these earlier calculations have generally been incorporated into an analytic model for the fraction of the weapon yield coupled into kinetic energy in the ground, the Peyton-Byrne model. The subject solicitation will be provided on the DTRA Homepage ONLY at www.dswa.mil/dswaproc/cont_act.htm. No hardcopy will be provided. All amendments to the solicitation (including questions and answers) will also appear on the home page. It will be your responsibility to view the home page frequently to note any changes or updates.
