Revision of the VGB Guideline for Water in Nuclear Power Plants with Light-Water Reactors - VGB-R 401 J. VGB working panel ''BWR chemistry''

The VGB Guideline for Water in Nuclear Power Plants with Light-Water Reactors (VGB-R 401J) is at the present time being revised. In this process, experience from material defects which have occurred world-wide is converted into improvements in chemical analysis and into further up-to-date knowledge. In currently available tables for boiling water reactor plant, adaptations to standards applicable in other countries are incorporated. The parameters embraced by the guidelines are discussed in relation to their influence on the performance of materials. (orig.)
