A -- AN INNOVATIVE COMPUTATIONAL METHOD FOR PREDICTING NEUTRON TRANSPORT POC Tanya Stasiuk, Negotiator, (703) 325-5029, Scott Morton, Contracting Officer, (703) 325-1200. Proposed contract effort is for computational simulation of the linearized Boltzmann transport equation to address the low energy neutron transport discrepancy of the current radiation transport codes. The contractor shall establish and benchmark a computational methodology for neutron transport based on the Boltzmann-Fokker-Planck equation and compare the computational methodology with atmospheric nuclear test data and current computational capabilities. Contemplated period of performance is 22 months. The Defense Nuclear Agency (DNA) intends to award a sole source contract to the University of Tennessee based upon its unsolicited proposal. The technical approach is an innovative method for solving the Boltzmann diffusion equation for application to low-energy neutron transport. The proposed method is unique and provides a completely fresh look at the thermal neutron discrepancy between calculations and measurements. No solicitation will be issued. For information contact Tanya Stasiuk, AMB, Defense Nuclear Agency, 6801 Telegraph Road, Alexandria, VA 22310-3398, phone (703) 325-5029, fax (703) 325-9295.
