The MCNP Unstructured Mesh (UM) Workshop, hosted by Los Alamos National Laboratory (LANL), is a course introducing the UM capabilities introduced in MCNP6 for modeling and simulating complex 3D shapes.

PHITS is a general-purpose Monte Carlo particle transport simulation code developed through international collaboration led by the Japan Atomic Energy Agency (JAEA). It simulates the transport of nearly all particles—including neutrons, protons, heavy ions, photons, and electrons—across wide energy ranges (from 10-5 eV up to 1 TeV).

TopMC is a multi-functional program for neutronics calculation, nuclear design, and safety evaluation. It is the updated version of SuperMC, focusing on high-efficiency particle transport simulations.

The XSUN/SUSD3D computer code package is a specialized software suite used for deterministic neutron/gamma (n/γ) sensitivity and uncertainty (S/U) analysis. It is designed to evaluate how uncertainties in nuclear data (such as cross-sections) affect calculations of radiation transport in shielding and reactor core applications.

The NEA Expert Group on the Physics of Reactor Systems (EGPRS) organized a workshop to foster exchanges among radiation transport simulation developers. The workshop aimed to facilitate exchanges among different code developer teams encompassing both scientific and commercial developers engaged in various radiation transport (RT) applications.

International Commission on Radiological Protection (ICRP) Committee 2 is responsible for the development of dosimetric methodology for the assessment of internal and external exposures, including reference biokinetic and dosimetric models and reference data and dose coefficients, for use in the protection of people and the environment. This workshop will overview the current works of Committee 2 and its Task Groups and discuss future works required to revise the dosimetry system of radiological protection for the next General Recommendations.

Aligned with the next General Recommendations of the International Commission on Radiological Protection (ICRP), the ICRP Task Group 103 have recently completed the development of the ICRP mesh-type reference computational phantoms (MRCPs) series for adults, children, and pregnant females (mother and fetus). This workshop will introduce the new ICRP reference phantoms, highlighting the backgrounds and rationales, overviewing the construction processes and the phantom characteristics, and demonstrating how to use the MRCPs in Monte Carlo radiation transport codes for dose calculations.

The PHITS-Attila4MC coupled shielding calculation method combines the precision of the Particle and Heavy Ion Transport Code System (PHITS) with the advanced variance reduction capabilities of Attila4MC, designed to efficiently solve deep penetration radiation shielding problems, particularly those involving complex CAD geometries.

This workshop will give an easy-to-understand update on the latest progress in advanced Small Modular Reactors (SMRs). We will look at new technologies, current development around the 재강, and how companies are preparing for future use of SMRs.
