Simulation of Tritium Spreading in Controlled Areas after a Tritium Release

Fusion Science and Technology, 2005
A model to simulate tritium behaviour after a release into a confined ventilated volume has been developed. The model assumes that for the investigated cases, tritium behaviour can be characterized by solving the dynamic equations of motion (the compressible Navier-Stokes equations) coupled with the classical k-[variant epsilon] turbulence model to ...

Tritium transport calculations for the IFMIF Tritium Release Test Module

Fusion Engineering and Design, 2014
Abstract The IFMIF Tritium Release Test Module (TRTM) is projected to measure online the tritium release from breeder ceramics and beryllium pebble beds under high energy neutron irradiation. Tritium produced in the pebble bed of TRTM is swept out continuously by a purge gas flow, but can also permeate into the module's metal structures, and can be ...

Tritium sorption by cement and subsequent release

Fusion Engineering and Design, 1995
Abstract In a fusion reactor or tritium-handling facilities, contamination of concrete by tritium and subsequent release from it to the reator or experimental room is a matter of problem for safe control of tritium and management of operational environment.

Tritium release assay for oleic acid desaturation

Analytical Biochemistry, 1972
Abstract The “tritium release” assay for the enzymic conversion of stearic acid into oleic acid introduced by Talamo and Bloch in 1969 (1) represented a major advance in the measurement of enzymic fatty acid desaturation. By measuring the release of tritium from the 9- and 10-positions of erythro-[9,103H2]stearic acid into water instead of isolating ...

Tritium Release from CTR Solid Blanket

Fusion Technology, 1985
In-situ tritium release behavior from Li/sub 2/O powder has been investigated under neutron irradiation at high temperatures. It was found that the chemical form of the released tritium depended strongly on the experimental conditions such as pre-treatment (dehumidification) of the sample and the H/sub 2/ addition to the sweep gas of helium.

Relation between the tritium in continuous atmospheric release and the tritium contents of fruits and tubers

Journal of Environmental Radioactivity, 2013
Concentrations of organically bound tritium (OBT) and tissue-free water tritium (TFWT, also referred to as HTO) in fruits and tubers were measured at a garden plot in the vicinity of the source of chronic airborne tritium emissions during the 2008, 2010, and 2011 growing seasons.

Behavior of Tritium Released to the Environment

2016
Tritium release from a fusion reactor consists of chronic one during the normal operation and accidental one. Once tritium (T) is released from the reactor, it disperses into environment. Because of its low energy of the β-electron released at T decay, internal exposure by T uptake (inhalation and ingestion) and its biological effects are major ...

Tritium releases and leukaemia clusters

Journal of Radiological Protection, 1999
Between 1989 and 1991 six children and one young adult developed leukaemia in the community `Elbmarsch' in Lower Saxony (northern part of Germany). Elbmarsch is located near to a nuclear power station (`Krummel') and since then Germany has had its `Sellafield', a leukaemia cluster next to a nuclear power station.

Tritium release from lithium silicate

Fusion Engineering and Design, 1989
Tritium release from lithium meta- and orthosilicate was studied inpile (LISA experiments) and out-of-pile. In addition to temperature, the dependence on neutron flux and purge gas flow rate, pressure and chemistry (additions of H2, O2 and moisture) were tested.

Release of tritium from boron carbide

J. Chem. Soc., Faraday Trans., 1990
The release of tritium from B4C powder and a single crystal has been investigated in the temperature range 400–800 °C. High-energy tritons, produced by bombarding a Cu target with 104 MeV α-particles, were used to prepare samples with a uniform tritium distribution.
