Kontec 2015

Kontec 2015

From 25th to 27th March 2015 the KONTEC 2015 - 12th international symposium "Conditioning of radioactive operational and decommissioning waste" including the 12th status report of the BMBF "Decommissioning and Dismantling of Nuclear Facilities" took place in the MARITIM Hotel & International Congress Center Dresden.

With over 1000 participants from 21 nations and 74 exhibiting companies on over 1,100 m2 of exhibition space, KONTEC 2015 was the most successful in its series of events since 1993.

The KONTEC Symposium has been held every two years since 1993 in the spring and brings together plant specialists, plant manufacturers, service providers, experts and official representatives to exchange information and experience. After the first KONTEC events from 1993 to 1999 in the Congress Center Hamburg (CCH), in the course of which KONTEC established itself as an international conference and the conference program was expanded to include the topic of the decommissioning of nuclear facilities with a focus on the conditioning of radioactive operational and decommissioning waste KONTEC moved its conference location to Berlin from 2001 to 2005 and took place there in the ESTREL Residence and Conference Hotel. Since 2007, KONTEC has been meeting very successfully in the MARITIM Hotel & International Congress Center Dresden.

Since 2003, the status report of the Federal Ministry of Education and Research BMBF on the research projects under the title "Decommissioning and Dismantling of Nuclear Facilities" of the Project Management Agency for Water Technology and Disposal (PTKA-WTE) of the Research Center Karlsruhe has been integrated into the conference program of KONTEC.

The KONTEC 2015 conference program for the 4 overarching topic groups

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

  • Decommissioning and dismantling of nuclear facilities

  • Plants and systems for the treatment and packaging of operational and decommissioning waste
  • Transport, interim and final storage of non-heat-generating waste

informed the participants in interesting and technically well-founded plenary lectures (38) and poster presentations (66), of which 16 posters were also presented in 10-minute short lectures as part of the "KONTEC DIREKT short lectures in words & pictures" format, about experiences, the latest developments and Trends from science and industry in the field of dismantling technology.

The following contributions received awards in the context of the KONTEC 2015 Best Paper Award:

Best Plenary Lecture:

"Quickly and safely cutting Zircaloy components"
by Mr. Hannes Jakob from the Institute for Materials Science at the Leibniz University in Hanover.

Best KONTEC DIREKT short presentation:

"Defined removal of highly reinforced steel structures"
by Mr. Ulrich Hess from the Institute for Manufacturing Technology and Machine Tools at the Leibniz University in Hanover
(Editor's note: Mr. Ulrich Hess, who unfortunately could not be present for the award ceremony, was presented with his prize after KONTEC 2015)

Best Poster:

"Mechanical evidence for the qualification of reactor pressure vessels and steam generators as TYPE IP-2 packages"
by Mr. Günther Neumann from the WTI Scientific-Technical Engineering Consulting GmbH

As an important part of the event series that has proven its worth since the beginning of KONTEC 2015, a trade exhibition was held at the same time and in the immediate vicinity of the large lecture room on more than 1100 m2, at which 74 companies from the industry presented their range of supplies and services and invited to dialogue.

As part of the KONTEC CAMPUS "Companies promote young people in nuclear technology" - a program that has been held at KONTEC since 2009 and is organized by Dr. Thomas Hassel, Head of the Underwater Technical Center in Hanover at the Institute for Materials Science, Production Technology Center Hanover (UWTH) and member of the KONTEC program committee, head of the project to promote young talent - thanks to the support of 11 well-known companies in the industry, a total of 24 students were able to take part in the event at KONTEC 2015 free of charge . After an informative introductory round at the start of the KONTEC CAMPUS, guided tours through the trade exhibition took place, where the participating students and interested trade exhibitors could exchange ideas directly. In the course of past KONTEC CAMPUS projects, there have already been numerous cooperation agreements between participating companies and students.

At the very well-attended evening event on Thursday, March 26, 2015, the "KONTEC 2015 Banquet", on the terrace level of the MARITIM International Congress Center, interesting conversations were held in a pleasant atmosphere and with delicious food and drinks, discussions deepened and new contacts made.

On Wednesday, March 25, 2015 at 10:00 am, Mr. Michael Szukala, Chairman of the KONTEC Program Committee, opened KONTEC 2015 and emphasized the strongest international participation since the beginning of the symposium series 22 years ago. The format of the KONTEC, with only plenary lectures, the KONTEC DIRECT short lectures, the poster presentations and the KONTEC CAMPUS characterize the attractive image of the symposium and thus invite intensive communication between the speakers, participants and exhibitors.
Mr. Michael Szukala particularly appreciated the achievements of Professor Dr.-Ing. habil. Dr.-Ing. eh dr hc Friedrich-Wilhelm Bach, who played a key role in shaping the face of KONTEC.

Afterwards, Ms. Sabine Diehr from the Federal Ministry of Education and Research BMBF spoke the words of welcome to KONTEC 2015 and, among other things, went into the special task of politics in the context of the initiated energy transition and the decision to phase out nuclear technology. In this context, she also emphasized the progress made in the major dismantling projects controlled and financed by the federal government at the former nuclear research facilities in Jülich and Karlsruhe.

In Section 1 "Disposal of radioactive residues from operation, decommissioning and dismantling of nuclear facilities" under the direction of Mr. Hans-Jürgen Blenski (GNS Gesellschaft für Nuklear-Service mbH) - as a representative for Dr. Günter Petzold - and Mr. Rudolf-Josef Printz (Research Center Jülich GmbH) were on Wednesday, March 25, 2015 6 plenary contributions entitled "Transport and Treatment of 15 Boilers from Berkeley NPP", "Dismantling and recycling of large components using the example of CASTOR® S1" , "Conditioning of fuel element boxes in the Mühleberg nuclear power plant, Switzerland", "Dismantling and packaging of irradiated BWR control elements of the Isar 1 nuclear power plant", "Building and site approval of the KWW - a review" and "Experiences in the implementation of the project Site Radwaste Treatment Facility ( SRTF), Sanmen, People's Republic of China”.
