Simulation-based evaluation of radiation effects at the interface between tritiated water and hydrophobic polymers used in detritiation systems Open
Due to the low energy of β-radiation emitted by tritium, measuring dose-depth profiles in hydrophobic materials at the catalyst-tritiated water interface is challenging. To address this issue, we developed a Geant 4-based model which can f…
Tritium Content Determination in Titanium Tritide Targets from Romanian Decommissioned Nuclear Facilities Open
The decommissioning or refurbishing processes of nuclear facilities result in significant amounts of radioactive wastes. Radiological characterization is essential to ensure safe handling, transportation, and disposal of these wastes and i…

Fuel desorption from JET-ILW materials: assessment of analytical approach and identification of sources of uncertainty and discrepancy Open
This work was carried out to identify sources of errors, uncertainties and discrepancies in studies of fuel retention in wall components from the JET tokamak using methods based on thermal desorption. Parallel aims were to establish good p…
SYNTHESIS OF TRITIUM LABELLED THYMIDINE AND URIDINE Open
This study present tritium labeling methods for uridine and thymidine in the methyl position. The synthesis of tritiated thymidine has been performed using two different methods: catalytic hydrogenation of brominated derivative and respect…

Recent Progress in Radon Metrology at IFIN-HH, Romania Open
The practical implementation of the European Council Directive no. 2013/59/EURATOM in Romania requires reliable indoor measurements of the radon (222Rn) activity concentration in air. In Romania, several Testing Laboratories were designate…
Characterization measurements of fluental and graphite in FiR1 TRIGA research reactor decommissioning waste Open
The objective of this article is to study the activities and special characteristics of graphite and Fluental neutron moderator material in FiR1 TRIGA Mark II type research reactor in Finland. Quantifying the nuclide vector and total activ…
Release of C-14 and H-3 from Irradiated Graphite of the Thermal Column of VVR-S Reactor to Gas Phase Open
14 C and 3 H are produced in all types of reactors, mainly through neutron-induced reactions with common isotopes of carbon, nitrogen and oxygen.They are present in the fuel, fuel cladding, coolant, moderator and structural materials of th…
Release of <sup>14</sup>C and <sup>3</sup>H from Irradiated Graphite of the Thermal Column of VVR-S Reactor to Solution Phase Open
Generally, 14 C is produced in all types of reactors, mainly through neutron-induced reactions with isotopes of carbon, nitrogen, and oxygen. These isotopes are present in the fuel, fuel cladding, coolant, moderator, and structural materia…
Effect of Irradiation and Temperature on Microstructural Characteristic of FeCrAl Alloys Open
Characteristics of FeCrAl alloys family are currently investigated in order to determine their behavior in different types of environment, erosive and corrosive (solid, liquid or gaseous), at high temperatures (400-1000 • C).The applicatio…
