The latest release of SCALE contains new shielding analysis tools that incorporate hybrid methods – a Monte Carlo code that uses importance maps and biased sources developed from course-mesh discrete ordinates calculations. The implementation into SCALE hides most of the details and makes the use of these advanced variance reduction techniques nearly automatic. Several example applications will be presented that would not be solvable without the variance reduction provided by the hybrid methods.
Dr. Douglas E. Peplow graduated from Western Illinois University with a B.S. Degree in Physics in 1991. He then received M.S. and Ph.D. Degrees both in Nuclear Engineering from North Carolina State University, in 1993 and 1999. His Ph.D. study was focused on Monte Carlo Mammography Image Simulation with Measured Coherent Scattering Form Factors and Differential Sampling. Currently, he is a Senior R&D Staff Member. Dr. Peplow has been with Oak Ridge National Laboratory (ORNL) for 10 years.
Refreshments will be served.
