Release of fission tritium through Zircaloy-4 fuel cladding tubes

, 2005
In order to analyse a potential fission tritium migration from the fuel to the coolant trough the cladding, two experiments of effusion and permeation types, have been performed on H-3 release from Zry4 claddings. During the tests at 350 degrees C, the 3

Study of ratio of tritium concentration in plants water to tritium concentration in air moisture for chronic atmospheric release of tritium

, 2011
Specific activity models (SA) are often used to estimate tritium concentration in the plants for chronic-release of atmospheric HTO in some regulatory models by some countries and commissions.

Tritium retention and release analysis for US-ITER blanket

, 1990
The US design for the ITER tritium-breeding blanket consists of layers of Be multiplier, stainless steel cladding, and Li{sub 2}O ceramic breeder. Tritium is recovered from the ceramic breeder by purging it with He + 0.2% H{sub 2}.

Studies of irradiated two-phase lithium ceramics Li4SiO4/Li2TiO3 by thermal desorption spectroscopy

Nuclear Materials and Energy
Two-phase ceramics Li2TiO3-Li4SiO4 are one of the potentially promising materials for creating a ceramic blanket for DEMO reactor. However, until now, a limited number of studies have been carried out on the release of tritium from this material under ...

Tritium content in water bodies in regions of peaceful nuclear explosions

Радиационная гигиена
Sites of peaceful nuclear explosions pose a potential radiation hazard to the territories of the Russian Federation, primarily due to the possible release of radioactivity from the explosion cavity into aquifers and onto the earth's surface.

Tritium inventory prediction in a CANDU plant

, 1995
The flow of tritium in a CANDU nuclear power plant was modeled to predict tritium activity build-up. Predictions were generally in good agreement with field measurements for the period 1983-1994.

BEATRIX-II: In situ tritium test [PDF]

, 1990
The BEATRIX-II irradiation experiment is an in-situ tritium release experiment being carried out in the Fast Flux Test Facility (FFTF) reactor to evaluate the tritium release characteristics of fusion solid breeder materials.

Effect of heat treatment of titanium beryllide on tritium/hydrogen release

, 2019
In the present paper, a homogenization heat treatment at 1473 K for 8 h was carried out with the aim to obtain the single-phase Be12Ti structure in the pebbles of three Be-Ti compositions: Be-7.0Ti, Be-7.3Ti, Be-7.7Ti at.%.

Release of tritium from tritiated paints

, 1974
A study of the tritium losses from five tritiated phosphor paints showed that the losses from these paints were generally low. Samples of five different paints which were leach tested six times over a period of 11 months had losses ranging from 0.018 to 0.731% of the initial activity in the samples. Tritium evolved from a paint which had been cured for

The Impact of Tritium in the Environment

Applied Sciences
Tritium is a radioisotope that is extremely mobile in the biosphere and that can be transferred to the environment and to humans mainly via tritium oxide or tritiated water.
