In the contribution we present a framework for computing realistic plasma neutron source models for ITER, based on coupling between the plasma transport code JINTRAC and the fusion kinematics code DRESS, and demonstrate its application to the MCNP neutron transport code. This allows capturing plasma events throughout the whole predicted scenario trajectory, including transients, and their...

This work presents a systematic optimization study of neutron source shielding for a dedicated multilayer bunker designed to house a cylindrical inertial electrostatic confinement (IEC) neutron source within the framework of the LIBRA project. LIBRA aims to investigate lithium deuteride (⁶LiD) as a tritium breeding material for future nuclear fusion applications.
The bunker design must...

Accurate evaluation of shutdown dose rate (SDDR) represents a key requirement in fusion reactor design and operation and is essential to ensure personnel safety throughout the entire lifetime of fusion facilities, in particular during maintenance and their decommissioning. SDDR tools have been developed for this purpose, among which JSIR2S, developed at the Jožef Stefan Institute, implements...

Miguel Macias (IFMIF-DONES Consortium)10/06/2026, 09:00Performance evaluationInvited
The properties of materials for nuclear fusion applications are not yet fully understood under the neutron irradiation conditions foreseen in future fusion reactors. IFMIF DONES is designed to address this gap by providing neutron irradiation conditions representative of fusion environments. IFMIF DONES is an accelerator-based neutron source composed of a deuteron injector, a Radio Frequency...

ANTONIO JESUS LOPEZ REVELLES (UNIVERSIDAD NACIONAL DE EDUCACION A DISTANCIA (UNED))10/06/2026, 09:20Radiation mappingOral
Radiological dose mapping in the IFMIF-DONES accelerator system poses a demanding neutronics problem because the radiation field is not governed by a single source term, but by the superposition of multiple contributions with different physical origins and spatial distributions. During beam-on, biological dose and absorbed dose in silicon are largely driven by neutrons and photons produced in...

The Start-Up Monitoring Module (STUMM) is currently under development as a dedicated calibration and diagnostic system intended for the commissioning stage of IFMIF-DONES. The module will be positioned in proximity to the neutron source, within the irradiation zone used for material testing. Its main purpose is to enable accurate characterization of neutron source parameters and prevailing...

The materials proposed for nuclear fusion applications have yet to be fully characterized under the neutron irradiation conditions expected in future fusion reactors. IFMIF DONES (International Fusion Materials Irradiation Facility – DEMO Oriented NEutron Source) has been conceived to address this challenge by irradiating materials under neutron conditions representative of those found in...

As part of the IFMIF/EVEDA project, the Linear IFMIF Prototype Accelerator (LIPAc) was constructed at Rokkasho, Japan, and a Superconducting Radio-Frequency (SRF) accelerator has been installed for the upcoming 9 MeV deuteron beam campaign. In the previous 5 MeV beam experiments, radiation transport analyses using MCNP relied on manually created geometry models including only major components....

Lithium targets are commonly employed to produce “fusion-relevant” neutrons in fusion technology validation facilities, where proton-lithium (p-Li) reactions serve as the primary neutron source. Accurate neutron production cross sections are critical for facility designs, shielding calculations, and dosimetry. However, the quality and consistency of available proton-induced lithium nuclear...

Mr Aleksei Pankratenko (ITER RF DA)11/06/2026, 15:40Neutron/gamma diagnostics and calibrationOral
The main goal of ITER operation is demonstration of fusion power reaching values up to 10 times greater than the supplied plasma heating power. This demonstration relies on the set of neutron diagnostics capable of measuring the neutron yield with 10% accuracy and of providing reliable data stream for regulatory purposes. The specified accuracy is planned to be achieved through in situ neutron...

The TU Dresden Neutron Generator (TUD-NG) is an accelerator-driven deuterium–tritium (DT) neutron source designed for fusion-relevant irradiation experiments. The facility delivers deuterium beams of several milliampere onto a water-cooled tritium target, producing neutrons via the 3H(d,n)4He reaction with energies around 14 MeV. The source is designed to reach neutron yields of up to 1012 n/s...

In late 80s-early 90s, two projects of accelerator-based 14-MeV neutron sources were conceived at the ENEA Research Center of Frascati, i.e., the Frascati Neutron Generator (FNG) and SORGENTINA, in response to specific needs of the scientific community involved in Controlled Thermonuclear Fusion. FNG (neutron strength up to 1.5x1011 s-1) was mainly to support the development and benchmark of...
