Activation of the dosimetric properties of potassium chloride crystal via doping with lithium ions
A high-temperature thermally stimulated luminescence (TSL) peak at 505 K has been identified in KCl:Li crystals. Its integral light yield ( η KCl:Li ) increases linearly with lithium ion concentration ( η KCl:Li ∼ f(С Li )), and with the dose of X-ray and gamma irradiation ( η KCl:Li ∼ f(D ))…

Laboratory evaluation of desiccation cracking and microstructure change of carbon fiber-reinforced bentonite subjected to thermo-hydro coupled environment for geological repositories
Deep geological repositories that utilize bentonite clay as an engineered barrier material offer a promising solution for isolating and containing waste from the surrounding environment. However, desiccation cracking of bentonite under thermo-hydro coupled conditions may compromise its…

A flexible silicone elastomer/copper oxide nanocomposite for current-mode X-ray dosimetry: Synthesis, characterization, and performance evaluation
Flexible, polymer-based nanocomposite dosimeters have attracted growing interest for radiation monitoring in diagnostic radiology because of their mechanical conformability and potential for low-cost, large-area fabrication. While silicone-based detectors loaded with heavier metal oxides have…

Impact of load conditions on single event transients in power supply circuit
Single-event transients (SETs) of the power supply circuit are investigated by conducting heavy-ion tests. The most sensitive device in the circuit whose SET response dominates the circuit functional degradation is identified. Then the impact of load currents and load types on the SET cross section…

Analysis of helical coil steam generator tube rupture with multiple failure accident at the innovative SMR using SPACE
Steam generator tube rupture (SGTR) accidents may occur due to degradation mechanisms in steam generator tubes, such as stress corrosion cracking and foreign object damage. A more severe accident scenario, referred to as multiple steam generator tube rupture (MSGTR), involves the simultaneous…

Reaction-dissolution characterization of corrosion products Ni and NiO under acid shutdown conditions
The dissolution and release behavior of nickel (Ni) and nickel oxide (NiO), primary corrosion products in nuclear reactors, were investigated under acid shutdown conditions. This study employs thermodynamic and kinetic analyses to elucidate the dissolution mechanisms and their dependencies on water…

Asymmetric loop seal clearing and reformation during a shutdown-cooling LOCA with single-loop passive cooling: ATLAS integral effect test and MARS-KS assessment
A loss-of-coolant accident (LOCA) initiated from a shutdown-cooling condition (shutdown-cooling LOCA) was investigated in the ATLAS integral effect test facility as the C4.2 test of the OECD-ATLAS3 joint project. The test simulated a 50 % direct vessel injection (DVI) line break of APR1400, with…

A variable-domain integral weak solution deep learning method for neutron diffusion calculations in multi-material domains
Neutron diffusion calculations are an important part of reactor physics analysis. In reactor models involving multi-material domains, diffusion coefficients and macroscopic cross sections are typically defined piecewise. Their discontinuities at material interfaces result in discontinuous neutron…

Experimental investigation of damage mechanisms and limit states for nuclear power plant electrical cabinets using tri-axial shaking table tests
Seismic fragility tests using tri-axial shaking table excitation were performed on representative safety-related electrical cabinets for nuclear power plants, namely two MCCs, two switchgears, an inverter, a battery charger, and a load center, to evaluate their ultimate limit states and dynamic…

Factor effect analyses on radionuclide release rate from a spent nuclear fuel transport cask submerged in deep sea for surrogate model development
In Korea, maritime transportation of spent nuclear fuel (SNF) is considered as a highly plausible management option. It is necessary to develop technology to assess the radiological impact of SNF cask submersion accidents to manage the risk caused by the maritime transportation of SNF and to find…

Automating real-time recovery from radiation-induced errors with byte-sized corrections
Radiation-induced errors in high-energy physics detectors threaten data integrity and uptime, posing significant challenges for reliable operation during the future high-luminosity LHC runs. With over 150,000 ASICs to be deployed in the CMS HGCAL front-end, even a very low per-chip error…

Few-shot class-incremental fault diagnosis in nuclear power plants via a static network-based method
The operational safety of nuclear power plants (NPPs) imposes a lifelong adaptability requirement on fault diagnosis systems: they must recognize newly emerging fault types from very limited samples while retaining diagnostic performance on previously learned faults. However, conventional…

A deployment-oriented single-channel integrity assessment and fault-subtype triage framework for in-core instrumentation loops
This study proposes a deployment-oriented single-channel integrity assessment and fault-subtype triage framework for in-core instrumentation loops using only normal-operation data. It couples normal-only reconstruction screening with deterministic rule-based subtype triage, rather than treating the…

Response-dependent layer ordering in fixed-inventory compact neutron–photon shields: Exhaustive OpenMC benchmarks at 2.45 and 14.1 MeV
Layer ordering can alter mixed-field shielding because each layer receives a neutron–photon field modified by upstream materials and leaves a different attenuation inventory downstream. This effect was isolated in a vacuum-bounded finite-slab shield containing 5 cm polyethylene, 5 cm borated…

An efficient prediction method of effective shunt impedance for IH-type drift tube linacs
In conventional drift tube linac (DTL) design, the determination of radio-frequency (RF) parameters relies heavily on iterative three-dimensional (3D) electromagnetic (EM) simulations, which imposes several limitations, including low efficiency in evaluating multiple design schemes. To overcome…

Temperature-dependent corrosion of structural alloys for molten salt reactors in NaCl-MgCl
The corrosion behavior of Inconel 600, SS316H, and Hastelloy C276 was investigated in molten NaCl-MgCl 2 eutectic salt by 500 h static immersion tests at 550 °C and 650 °C. Mass change measurements, SEM-EDS, and XRD were combined to relate alloy degradation to surface and subsurface microstructural…

Integrating compartment-based hydraulic flood propagation with seismic fragility for dynamic risk assessment of combined events in nuclear power plants
This study presents a time-dependent dynamic probabilistic risk assessment (PRA) framework that integrates seismic equipment fragility, compartment-based hydraulic flood propagation, component water-height fragility, and event-tree quantification. The framework is applied to a combined earthquake…

Clause-level structural alignment between ASME Section III and Czech NTD A.S.I. Section III: Domain- and component-resolved assessment
Comparative studies of nuclear pressure-boundary component design codes have focused mainly on selected provisions and governing equations, but domain- and component-resolved clause-level quantification between ASME Section III and NTD A.S.I. Section III has not been systematically reported. This…
