Abstract
The corrosion potential is a useful parameter to monitor the water chemistry of a nuclear power plant (NPP). However
the harsh conditions in the core of a nuclear reactor make it difficult to construct a reference electrode for this location.
An attempt has been made to construct such a reference electrode based on the well-known yttrium stabilized zirconia
(YSZ) membrane electrode. The YSZ electrode is constructed only from radiation-resistant materials (ceramics
and metals) and can survive temperatures up to 350 °C. Special emphasis has been put on the ceramic-metal seal,
which is a crucial part of the design.
