The Nuclear Safety Standards Commission (Kerntechnischer Ausschuss - KTA) consists of 35 members in five groups of seven members each.
The KTA Safety Standards are issued with a 5/6 majority vote (30 positive votes necessary) of the 35 members, meaning each of the 5 KTA-groups has a blocking minority.
