Description
The paper discusses methods developed in Germany for measurements of hydrogen concentration and airborne nuclide concentration in the containment atmosphere, which are due to provide additional information on the accident history, plant status and effects of countermeasures to reduce hydrogen concentration, and also to help assessing the potential hazard in the vicinity of the plant. In-site hydrogen measurements as well as measurement through extractive sampling are discussed, the former system, using sensors in the containment, providing continuous and simultaneous information displayed in the control room without radiation exposure. Regarding containment atmosphere activity monitoring, the difficulties of extraction pipe systems are described and some preference is given to in-containment sampling and to pool sampling system.
