A Nonselective Automatic Method for Kinetic Simulations of Gas Mixtures under Ionizing Radiation: Case Study of a Nuclear‐to‐Chemical Concept

Chemistry–Methods, Volume 5, Issue 12, November 2025.
This study presents here a versatile and automated method based on open‐access curated databases for complex mixture radiolysis kinetic modeling. The case study is a nuclear‐to‐chemical concept. This method provides a robust way for concept evaluation and could pave the way for radiation‐induced technology development in chemical processing.

Water quality monitoring of Reactor TRIGA PUSPATI

IOP Conference Series: Materials Science and Engineering, 2020
Abstract At present, Reactor TRIGA PUSPATI (RTP) is the only nuclear research reactor in operation in Malaysia since 1982. Each year, the reactor is operated on average for about 600 hours mainly for the advanced neutron and gamma radiation studies as well as for isotope production, sample activation and student training. About one-third

The Transition to Tectonic Control of Magmatism in the East African Rift System—The 20 Ma Samburu Event

Tectonics, Volume 44, Issue 9, September 2025.
Abstract The Samburu Series magmas of the East African Rift System are a key component of the Early Miocene magmatic resurgence, marking the initiation of plate‐scale volcanic events associated with extension, distinct from the prior continental flood basalt episodes.

Structural Architecture of the Cenozoic Kallianos (Post‐?)Orogenic Vein‐Hosted Au‐Ag‐Te Deposit and Its Relationship to the North Cycladic Detachment System, Greece

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract The Kallianos Au‐Ag‐Te deposit is a Cenozoic orogenic‐style deposit on Evia, hosted in the Cycladic Blueschist Unit. Integrated field observations and isotopic data illustrate a connection between the structural architecture that hosts mineralization in the deposit and the regional stress field associated with a crustal‐scale detachment, the ...

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

The Depositional Record, Volume 11, Issue 3, Page 954-974, June 2025.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

Simulation of a TRIGA Reactor Core Blockage Using RELAP5 Code

Science and Technology of Nuclear Installations, 2015
Cases of core coolant flow blockage transient have been simulated and analysed for the TRIGA IPR-R1 research reactor using the RELAP5-MOD3.3 code. The transients are related to partial and to total obstruction of the core coolant channels.

Early Cretaceous to Miocene Tectonic Evolution of the NW Cyclades Based on 40Ar/39Ar Multiple Single Crystal Dating of White Mica From Andros

Tectonics, Volume 44, Issue 6, June 2025.
Abstract The Aegean region marks the convergent boundary between the African and Eurasian plates, reflecting complex tectonic processes, including the closure of the Pindos ocean. The Pelagonian unit (PU) forms the core of mainland Greece and was part of the Eurasian continental margin, while the Pindos oceanic crust subducted beneath it.

The Hydroclimate and Environmental Response to Middle Miocene Warming in the Southwestern USA: Stable Isotope Evidence

Paleoceanography and Paleoclimatology, Volume 40, Issue 5, May 2025.
Abstract Predictions for the southwestern US with warming often suggest increased aridity. We investigate the sedimentary record of the Miocene Climate Optimum and Transition (MCO and MCT; ∼17–14 Ma) in northern New Mexico to understand the impact of warmer global temperatures and higher pCO2 on southwestern US hydroclimate. The MCO and MCT comprised a

Temperature-induced corrosion of the TRIGA 2000 research reactor tank liner in long-term normal operation

Results in Engineering
Aluminum alloy AA-6061-T6 is widely used as the tank liner in nuclear reactors due to its corrosion resistance and low neutron absorption. However, prolonged exposure induces degradation, threatening structural integrity and operational safety.
