      <p id="d1e89">Nowadays, concrete decontamination is done by, e.g., grinding, milling, etc.,
always combined with labor resources. In order to relieve employees from the
monotonous and physically stressful decontamination work, a novel milling
system for automated surface decontamination has been developed and
assembled. The current work presents this new concept for a milling tool that
could automatically position itself to the wall surface and subsequently
remove surface contamination. A process chain (Fig. 1) defined in the German
Federal Ministry of Education and Research (BMBF)-funded project ROBDEKON was
introduced first. The chain consists of a total of five steps for a compact
process, from environmental exploration to the transportation of waste. This
automated decontamination is the third step in the process chain for
decontamination of building structures in nuclear facilities. The structure
(Fig. 2) of the milling system and the function of each component
are then explained in detail. With the assembled sensors, such as a
laser distance sensor, a force sensor etc., the various physical quantities
can be measured in real time, thus enabling automation of the milling process
during decontamination.</p>

      <p id="d1e94">Heutzutage erfolgt die Betondekontaminierung, z. B. durch
Schleifen, Fräsen usw., immer in Verbindung mit Arbeitskräften. Um
die Mitarbeiter von diesen monotonen und körperlich belastenden Arbeiten
zu entlasten, wird ein neuartiges Frässystem zur automatisierten
Oberflächendekontaminierung entwickelt und montiert. In unserer Arbeit
wird das Konzept für dieses Fräswerkzeug vorgestellt, das sich
automatisch an der Wandoberfläche positionieren und anschließend die
Oberflächenverunreinigung entfernen kann. Zunächst wird eine im
BMBF-geförderten (BMBF: Bundesministerium für Bildung und
Forschung) Projekt ROBDEKON definierte Prozesskette (Abb. 1)
vorgestellt. Diese besteht aus insgesamt 5 Schritten für einen kompakten
Prozess von der Umwelterkundung bis zum Abfalltransport. Die automatisierte
Entfernung der radioaktiven Verunreinigungen ist der 3. Schritt der
Prozesskette zur Dekontaminierung von Gebäudestrukturen in
kerntechnischen Anlagen. Anschließend werden der Aufbau (Abb. 2) des
Frässystems und die Funktionen der einzelnen Komponenten
ausführlich erläutert. Mit den montierten Sensoren wie
Laserdistanzsensor, Kraftsensor usw. können die verschiedenen
physikalischen Größen in Echtzeit gemessen werden und
ermöglichen so die Automatisierung des Fräsprozesses bei der
Dekontaminierung.</p>
