  • An overview of MCNP with respect to current and future application-driven code development activities at LANL
  • Review and demonstration of previously released MCNP6.2 features and tools
    • Correlated fission physics integrated through CGMF and FREYA
    • Intrinsic Source Constructor (ISC) for source definitions of radioactive material compositions
    • MCNPTools capabilities for improved access and analysis of MCNP outputs
  • New upcoming MCNP6.3 features and improvements
    • HDF5-based outputs including the restart file (runtpe), particle track file (ptrac), fmesh tally file (meshtal), unstructured mesh elemental edit file (eeout), and surface source read and write files (wssa/rssa)
    • Modern parallel-capable and highly efficient particle track buffer and output capability (ptrac)
    • Multigroup cross section generation through new special treatment tally options
    • Several speed and memory-usage performance improvements generally targeted toward large unstructured mesh burn-up applications
    • Automated and expanded V&V testing for many applications

Participants will be provided with workshop slides, examples and any corresponding documentation.  Instructors will be available to discuss participant questions regarding the workshop materials and their specific application needs.

 

Attila

Attila4MC provides a graphical user interface for MCNP 6.2, allowing users to setup, run, and visualize MCNP solutions from CAD data. Attila4MC employs the Attila deterministic solver to generate weight windows variance reduction using the CADIS and FW-CADIS methods. This is a hands-on workshop, where attendees will setup, run, and visualize a deep penetration shielding model starting with a CAD model. Both the CADIS and FW-CADIS variance reduction models will be employed. Attendees wishing to run Attila4MC should bring a Windows 7 or 10 laptop, with at least 6 GB of RAM. Attendees wishing to also run MCNP must also have MCNP 6.2.0 installed.

 

Shift

Shift is Oak Ridge National Laboratory’s flagship Monte Carlo (MC) radiation transport code, designed to scale from laptops to leadership-class supercomputers. As a general purpose MC code widely used for fission, fusion, and national security applications, Shift supports a variety of geometry representations, physics engines, and tally types. Shift will be available as a user-facing tool in the SCALE 6.3 release in late 2020.This workshop will cover the basic usage of Shift for fixed-source shielding problems. Attendees will first be guided through input file setup, code execution, and output interpretation. Two realistic use cases will then be explored in detail. The first will involve using hybrid MC/deterministic transport capabilities (i.e., CADIS/FW-CADIS) for a multi-detector shielding problem. The second will be an SMR excore problem, where Shift is first run in eigenvalue mode to obtain a converged fission source for fixed-source transport.The workshop will conclude with an interactive exercise where attendees can practice using Shift and ask questions as they arise. For this exercise, attendees will be provided with a VirtualBox appliance file with Shift pre-installed. Attendees should bring a laptop and also apply in advance for a license for the SCALE software package (version 6.2 is fine) from RSICC (https://www.ornl.gov/onramp/rsicc).

Proton Therapy

The first radiation therapy treatment was in 1893, and since then, x-rays have been the standard of care in radiation oncology. Recently, there has been massive growth in proton therapy centers in the US and worldwide, due to the reduced risk of side effects and secondary malignancies offered by proton therapy compared to x-rays. These benefits come with unique challenges, including larger and more expensive delivery equipment, uncertainties in treatment delivery, and sensitivity to anatomical changes. In order to treat cancer safely and effectively, protons travel a journey through a cyclotron, magnetic beam line, a 3-story rotating gantry, powerful scanning magnets, a brass aperture, and finally, the patient. Throughout this journey, Radiation Oncologists, Medical Dosimetrists, Medical Physicists, and Radiation Therapists are developing the necessary treatment plans to guide the protons into the tumor and away from healthy organs. We are just starting to glimpse the future of proton therapy and it is very positive.

 

RayXpert

RayXpert is a 3D modeling software associated to a Monte Carlo calculation code for the Nuclear and Medical fields. Our Monte Carlo code is based on GEANT4, but totally re-developed by our company TRAD Tests & Radiations since 2000s.
Thanks to the different tools RayXpert offer you, you will be able to optimize the design of your shielding with 3D mapping and scripting functionalities.
If you are provided with the CAD files corresponding to your electron beams for example, this will even easier to model your case since RayXpert can import directly CAD file (STEP format) so that you don’t have to re-model everything.
You will also be able to compute the dose rate and deposited dose in terms of Gy in the different shapes you are interested in, or in terms of Sv (H*(10) definition or other dosimetric factor) for radioprotection purposes. And the system allows you to launch your calculation on your Linux or Windows cluster of computers with the distributed computation module.
Finally, the software is validated comparing to MCNPX, for Gamma and Beta energies from 1 keV to 100 MeV, and for Neutron from 10^-11 MeV to 20MeV, and it is used worldwide (including US) by more than 40 companies.
During the workshop we will present you the main functionalities of RayXpert through a real case study: the design of our own bunkers in which we have a Co60 and an electron beam source. From the design of the building to the shielding design of our home-made electron generator.
Participant will be provided with the software at the beginning of the workshop that we will install in live on your computers, and let you use the 3D model we will work on to setting up the sources and materials, launch calculations and optimize the shielding.
Presentation performed by a Nuclear Physicist from TRAD Tests & Radiations.
