Simulation of Tritium Behavior after Intended Tritium Release in Ventilated Room [PDF]

Journal of Nuclear Science and Technology, 2001
At the Tritium Process Laboratory (TPL) at the Japan Atomic Energy Research Institute (JAERI), Caisson Assembly for Tritium Safety study (CATS) with 12 m3 of large airtight vessel (Caisson) was fabricated for confirmation and enhancement of fusion reactor safety to estimate tritium behavior in the case where a tritium leak event should happen.

Updated Estimates of Radiocarbon‐Based Deep Ocean Circulation Age

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract The deep ocean circulation age based on radiocarbon was last determined almost 20 years ago, when digital archiving was not standard practice. This work updates the circulation age while making two improvements by using new nutrient data and modifying the calculation. The newly calculated circulation age is spatially more coherent and older in

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, Volume 68, Issue 11, Page 3947-3961, November 2026.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Vadose Zone Transport of Tritium and Nitrate under Ponded Water Conditions

Geosciences, 2022
Vadose zone transport of tritium and nitrate can be important considerations at radioactive waste sites, landfills, or areas with industrial impacts. These contaminants are of particular concern because they typically have a relatively higher mobility in

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, Volume 199, Issue 7, Page e327-e330, 3/10 October 2026.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Analysis of hydrogen isotope release from lithium ceramics with closed pores and different distributions

Nuclear Materials and Energy
In this study, a tritium transport model in lithium ceramics with closed pores was developed. Based on the dynamic equilibrium equations of tritium adsorption and desorption on the top-most surface of the closed pore and the vacant core of the closed ...

Advanced MXene‐Based Multifunctional Nanoarchitecture Materials Engineered for Adsorptive Cleanup of Hazardous Radioactive Pollutants: A Comprehensive Critical Review

Advanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
This work critically reviews MXenes as highly effective multifunctional nanomaterials for the adsorption of radio‐contaminants, demonstrating a remarkable adsorption capacity of up to 1376.75 mg/g and cyclic stability of 2–8 cycles, with complexation, electrostatic interactions, and the numerical strength of MXene active sites playing a key operational

Cuticular Barcoding—A Novel Method for Host Identification From Adult Parasitoid Wasps

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our manuscript presents a novel molecular tool that permits host detection of an adult parasitoid wasp. Our non‐destructive method, that we here tested in a laboratory experiment, allows studying the intricate interactions between parasitoids and their hosts while preserving the parasitoid as voucher specimen for subsequent morphological identification.

Calculation of tritium release from driver fuels into primary coolant of research reactors

Physical Sciences and Technology, 2019
Increasing of tritium concentration in the primary coolant of the research and test reactors during operation had been reported. To check the source for tritium release into the primary coolant during operation of the JMTR and the JRR-3M, the tritium ...

Dose Delivered by Unit Amount of Tritium Released into the Environment [PDF]

Journal of Nuclear Science and Technology, 1997
Dose conversion values (DCV: Sv/kg-Tritium release) associated with a release of tritiated hydrogen (HT) to the atmosphere have been studied in the field experiment performed at Chalk River Laboratories in Canada in 1987. For a near ground-level release of HT, DCVs of 2×10−2 and 3×10−3 Sv/kg-Tritium were evaluated at distances of 100 and 400m on the ...
