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.

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 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 ...

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.

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 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.

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
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 ...

In order to quantify tritium impact on the environmental, we studied vegetation continuously exposed to a tritiated atmosphere. We chose lichens as bio-indicators, trees for determination of past tritium releases of the Valduc Centre, and lettuce as edible vegetables for dose calculation regarding neighbourhood.

TRITIUM RELEASE FROM NUCLEAR POWER PLANTS IN TAIWAN
Health Physics, 2003Tritium is produced in light water reactors from various sources and the design source terms for both BWR and PWR plants are reviewed. The chemical forms of tritium produced in the coolant are discussed in terms of water radiolysis and free radical reactions in the reactor core regions, and the major form of tritium released from the coolant systems is
