Regrowth of Tritium Release from Tritium Contaminated Materials
Fusion Technology, 1995Regrowth in tritium desorption from type 316 stainless steel, copper and borosilicate glass was studied. It was found that the tritium, which was penetrated into materials by long term contact, could not be easily desorbed by a stream of nitrogen gas ( dry, wet or 10 % H 2 ) at room temperature. The ratio of the tritium amount desorbed from surface by

The Significance of Tritium Releases to the Environment
IEEE Transactions on Nuclear Science, 1972Tritium is produced naturally and was present in low concentrations in precipitation and natural bodies of water before atmospheric testing of nuclear weapons. Other sources of tritium are now present from which tritium is released to the environment.

Tritium transport calculations for the IFMIF Tritium Release Test Module
Fusion Engineering and Design, 2014Abstract 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 ...

Simulation of Tritium Spreading in Controlled Areas after a Tritium Release
Fusion Science and Technology, 2005A 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 Release from CTR Solid Blanket
Fusion Technology, 1985In-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.

Behavior of Tritium Released to the Environment
2016Tritium 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 release assay for oleic acid desaturation
Analytical Biochemistry, 1972Abstract 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 sorption by cement and subsequent release
Fusion Engineering and Design, 1995Abstract 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.

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.

Tritium Behavior Intentionally Released in the Room
Fusion Science and Technology, 2008To construct a fusion reactor with high safety and acceptability, it is necessary to establish and to ensure tritium safe handling technology. Tritium should be well-controlled not to be released to the environment excessively and to prevent workers from excess exposure. It is especially important to grasp tritium behavior in the final confinement area,
