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.

Tritium dissolution in and release from li2o

Fusion Engineering and Design, 1989
The solubility of tritium in Li 2 O crystals equilibrated with HT-H 2 and T 2 gas was measured. The solubility of tritium in Li 2 O was found to obey Sieverts' law. The Sievert's constants K s for hydrogen and tritium dissolution in Li 2 O were determined to be log K s = (1271 ± 46)/ T + (2.33 ± 0.07) atm 1/2 and log K s = (1290 ± 81)/ T +

Tritium Release from Silica Glass

Fusion Science and Technology, 2002
We investigated tritium (T) release behavior from silica glass. The specimens were 8 kinds of commercially available silica glass. T was injected by the 6Li (n,α)T reaction of sintered pellets of lithium oxide (Li 2 O) into the silica glass with thermal neutrons in JRR-2 (VT-8) up to 5 × 10 18 neutrons/cm 2 at ambient temperature (about 350 K).

Overview of the Tritium Release Experiment in France

Fusion Technology, 1988
The results show the dominating influence of the soil on the HT -> HTO conversion rate and allow the qualification of existing computer models.

Tritium Behavior Intentionally Released in the Room

Fusion Science and Technology, 2008
To 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,

Measurement of Uptake and Release of Tritium by Tungsten

Fusion Science and Technology, 2015
Tungsten is currently contemplated as plasma facing material for the divertor of future fusion machines. In this paper the uptake of tritium by tungsten and its release behavior have been investigated. Tungsten samples have been annealed at various temperatures and loaded at also different temperatures with deuterium containing 7.2 % tritium at a ...

Lessons to be learned from a tritium release

Conference Record for 1992 Fifth Conference on Human Factors and Power Plants, 1992
In December 1991, equipment breakdowns resulted in a tritium release at the Department of Energy's (DOE's) Savannah River K-Reactor. A description of the event is presented with emphasis of human factors lessons to be learned. The authors describe the changes in culture that are occurring within the DOE's nuclear complex as the DOE seeks to adopt the ...
