Nuclear safety standard commission (Kerntechnischer Ausschuss KTA, VGB = KTA-consortium)
The KTA has the task of establishing safety rules for producers and operators of nuclear installations and promoting their application. These KTA rules are similar, for example, to German standards with "DIN".
WALTHER is listed in the VGB and thus entitled to manufacture products of the requirement class K5 for nuclear facilities; K4-products on request.
