KONTEC 2015 – 12th International Symposium “Conditioning of Radioactive Operational & Decommissioning Wastes” including 12th Status Report of BMBF “Decommissioning and Dismantling of Nuclear Facilities” took place from March 25 through March 27, 2015 at the MARITIM Hotel & Internationales Congress Center Dresden at Dresden, Germany.

More than 1.000 attendees from 21 nations and 74 exhibitors on over 1.100 square metres exhbition space made KONTEC 2015 the most successful in its series since 1993.

KONTEC takes place in spring every 2 years and convenes power plant operating experts, equipment manufacturing experts and service people as well as reviewers and authorities representatives for exchange of information and experience. In the course of the KONTEC symposium series 1993 through 1999 in Hamburg and 2001 through 2005 in Berlin and since 2007 in Dresden, KONTEC could be extended into an international symposium which adopted decommissioning as a new topic, thereby establishing KONTEC as an important instrument for the exchange of information and experiences for the experts of this branch of industry.
Since 2003 already the results of BMBF’s r&d program “Decommissioning and Dismantling of Nuclear Facilities” (project executing organisation PTKA-WTE of Resarch Centre Karlsruhe, BMBF’s subordinate research unit) are being integrated into the KONTEC’s conference programme).

The KONTEC 2015 conference programme assigned to the following four main topics

Disposal of radioactive residues from nuclear facilities‘ operation, decommissioning
and dismantling

Decommissioning and dismantling of nuclear facilities

Facilities and systems for the conditioning and packaging of operational and
decommissioning wastesn

Transport, interim and final storage of non-heat generating wastes

informed the attendees in interesting and technically well-founded plenary papers (38) and poster presentations (66), of which 16 posters were additionally presented in 10 minutes technical short lectures in the course of „KONTEC DIRECT technical short lectures in word & vision“, about experiences, newest developments and trends from science and industry in the field of dismantling technology.

The following contributions were awarded in the course of the KONTEC 2015 Best Paper

Best Plenary Paper:

„Cutting Zircaloy components quickly and safely“
by Mr Hannes Jakob of the Institut für Werkstoffkunde of the Leibniz Universität Hannover.

Best KONTEC DIRECT technical short lecture:

„Defined removal of reinforced concrete“
by Mr Ulrich Hess of the Institut für Fertigungstechnik und Werkzeugmaschinen of the Leibniz Universität Hannover (Editorial note: Mr Hess was unfortunately not able to attend the award. His award was presented to him afterwards.)

Best Poster:

„Mechanical Verifications for the Qualifications of Reactor Pressure Vessels and Steam Generators as IP-2-Packages“
by Mr Günther Neumann of the WTI Wissenschaftlich-Technische Ingenieurberatung GmbH

As one further important feature of the KONTEC symposia, also at KONTEC 2015 a technical exhibition on over 1.100 square metres exhibition space took place in parallal and in close proximity to the lecture hall. 74 well-known companies of the branch showcased all aspects of the products and services and invited for dialogue.

Under KONTEC CAMPUS „Companies support new blood in the nuclear industry”, a KONTEC project running since 2009, led by Mr Dr. Thomas Hassel, Head of the Unterwassertechnikum Hannover at the Institut für Werkstoffkunde, Produktionstechnisches Zentrum Hannover (UWTH) and member of the KONTEC Programme Committee, 24 students could attend the conference free of charge thanks to 11 well-known companies of the branch.
KONTEC CAMPUS 2015 started with an informative introductory kick-off meeting, followed by – among others – guided tours through the technical exhibition, where the students and interessested exhibitors had opportunities to talk to each other directly. Numerous cooperation agreements between KONTEC CAMPUS sponsors and students could be developed already during the past KONTEC CAMPUS projects.

The social evening event “KONTEC 2015 Banquet” took place on the terrace level of the MARITIM Internationales Congress Center Dresden on Thursday, March 26, 2015 and was very well attended. In a pleasant atmosphere with delicious food and drinks the attendees had interesting conversations, discussions were deepened and new contacts were established.

Mr Michael Szukala, Chairman of the KONTEC Programme Committee, opened the conference on Wednesday, March 25, 2015 at 10.00 and highlighted the strongest international participation since the beginning of the KONTEC series 22 years ago. The KONTEC format consisting of plenary papers, KONTEC DIRECT short technical lectures, poster presentations and KONTEC CAMPUS characterizes the attractive image of the symposium and invite for intensive communication between speakers, attendees and exhibitors.
Mr Michael Szukala highly appreciated in particular the achievements of Mr Professor Dr.-Ing. habil. Dr.-Ing. E. H. Dr. H. C. Friedrich-Wilhelm Bach, who coined the face of KONTEC decisively.

Thereafter, Ms Sabine Diehr of the German Federal Ministry of Education and Research BMBF welcomed the KONTEC attendees and went in her speech on the politic’s particular task in the course of the introduced energy transition and the phasing out of nuclear technology so decided. Ms Diehr stressed in this context the progress made in the federally controlled and funded large decommissioning projects at the former nuclear research centers in Jülich and Karlsruhe.

In Plenary Section 1 “Disposal of radioactive residues from nuclear facilities’ operation, decommissioning and dismantling” chaired by Mr Hans-Jürgen Blenski ((GNS Gesellschaft für Nuklear-Service mbH) – as substitute for Mr Dr. Günter Petzold – and Mr Rudolf-Josef Printz (Forschungszentrum Jülich GmbH) on Wednesday, March 25, 2015 6 plenary papers topically complemented through 22 poster presentations were presented.

On Wednesday, March 25, 2015, afternoon plenary section 2 „Decommissioning and dismantling of nuclear facilities“ started chaired by Ms Anja Graf (WAK Wiederaufarbeitungsanlage Karlsruhe Rückbau- und Entsorgungs GmbH) and Mr Dr. Helmut Steiner (Kernkraftwerk Gundremmingen GmbH) and was continued on Thursday, March 26, 2015 with the Chairmen Mr Michael Bächler (E.ON Technologies GmbH) and Mr Peter Hildwein (Siempelkamp NIS GmbH). 15 plenary and 16 posters were held in this section.

Plenary Section 3 „Facilities and systems for the conditioning and packaging of operational and decommissioning wastes“ was held on Thursday, March 26, 2015 in the afternoon chaired by Mr Dr. Thomas Hassel (Unterwassertechnikum Hannover am Institut für Werkstoffkunde, Produktionstechnisches Zentrum Hannover (UWTH)) and Mr Dr. Michael Weigl (Karlsruher Institut für Technologie (KIT)) with 8 plenary papers and 19 poster presentations.

Chaired by Mr Dr. Heinz Geiser (formerly GNS Gesellschaft für Nuklear-Service mbH) and Mr Olaf Oldiges (DAHER-NCS GmbH) plenary section 4 on Friday, March 27, 2015 presented 9 plenary papers and 10 posters.
