Virginia Tech Transport Theory Group ‐ VT 3 GVisionTo be able to perform detailed 3‐D, timedependent,neutral‐ and charged‐particletransport calculation efficiently (computertime & engineer’s time) and accurately forapplication to power, safeguards andnonproliferation, and medicineNuclear EngineeringProgram14
VT3G ‐Advanced Computer codes/Formulations/AlgorithmsOver the last 26 years, VT3G has developed numerousadvanced formulations and computer codes, and applied thesecodes to real-world problems.Advanced numerical formulations:Differencing schemes (DTW, EDW, ADS), Cross-section generation (CPXSD),angular quadrature (Pn-Tn, Ordinate Splitting, fictitious), acceleration scheme(EP-SSn), response function for subcritical multiplication, & hybrid techniquesTransport codes• PENTRAN (Parallel Environment Neutral-particle TRANSport) – A 3-D parallelparticle transport code, Sjoden and Haghighat, 1997.• A 3 MCNP – Automated Adjoint Accelerated MCNP for Monte Carlo neutral particletransport with automated variance reduction, Wagner and Haghighat, 1997.• TITAN –A 3-D Hybrid parallel transport code, Yi and Haghighat, 2007.• ADIES - Angular-dependent Adjoint Driven Electron-photon Importance Samplingfor Monte Carlo electron transport with automated variance reduction, Dionne andHaghighat, 2007.Cross-section generation code• CPXSD – Contributon Point-wise cross-section Driven for generation of arbitrarymultigroup cross-section librariesSpecialized Hybrid methods/algorithms/codes• TITAN-SPECT algorithm• INSPCT-S (inspection of spent fuel pool)• AIMS (Active Interrogation for Monitoring of Special-nuclear-materials) PENTRANstTITANADIES0 2 1AIMS ln r 5453 0.580498 0.561644 0.491674 0.420538 0.353999 0.28285 0.27647 0.897903 0.880437 0.770597 0.653747 0.543993 0.427576 0.38686 1.271323 1.252983 1.094413 0.922518 0.761393 0.591298 0.49337 1.696988 INSPCT‐S1.669344 1.453015 1.219392 1.002015 0.772365 0.59258 1.978009 1.923356 1.665877 1.394836 1.14574 0.880125 0.67336 1.093457 1.058167 0.914234 0.765146 0.628852 0.482792 0.3tNuclear EngineeringProgram
