The Nuclear Hilfsdienst GmbH (KHG) is one of the German nuclear technology supported -Industrie private company, which at fault and accidents in nuclear facilities for security to be used.

Object of the company and structure

The KHG was founded in 1977 by operators of German nuclear power plants , the fuel cycle industry and large research centers. The largest share (87.6%) in KHG today is held by the “Beteiligungsgesellschaft der Energieversorgungsunternehmen an der KHG GbR”, represented by EnBW Kraftwerke AG , E.ON Kernkraft GmbH , RWE Power AG and Vattenfall Europe . The company headquarters are in the immediate vicinity of the Karlsruhe Research Center (formerly the Karlsruhe Nuclear Research Center ) in Eggenstein-Leopoldshafen .

According to the commercial register announcement of January 29, 2004, the object of the company is the establishment, operation and use of a nuclear technical support service as a facility within the meaning of Section 53 of the Radiation Protection Ordinance (“Preparing to combat damage in the event of safety-relevant incidents”) since 2019 Regulation). The company maintains the necessary personnel and the necessary aids to contain or eliminate the dangers arising from accidents or incidents within controlled areas and operational monitoring areas.

The core of permanent employees is involved in constant on-call duty and, in the event of an emergency, moves to the location with the vehicles available at the company headquarters. There he is supported by other people who have been instructed in the equipment and provided by the companies involved. There are 111 employees from 11 companies. With these external personnel, depending on their qualifications and intended use, training courses on KHG equipment and facilities as well as exercises for operators from the KHG shareholders' group are carried out. Several KHG employees are permanent members of the emergency protection working group in the Association for Radiation Protection eV and in the Emergency Protection Committee of the Federal Radiation Protection Commission (SSK).

There is an agreement on mutual assistance with “Groupe Intra”, a French organization with similar tasks. On the occasion of the 40th anniversary of the KHG, an exercise with Groupe Intra took place on the KHG premises in 2017.

The KHG regularly participated in round robin tests and comparative measurements by the Federal Office for Radiation Protection (BfS) on nuclear radiation measurement technology and took part in exercises on emergency preparedness in nuclear facilities.

On April 21, 2020, the federally owned BGZ Gesellschaft für Zwischenlagerung reported its intention to take over KHG to the Federal Cartel Office for examination.

Departments

Kerntechnische Hilfsdienst GmbH is divided into the departments of infrastructure , radiation protection , decontamination and remote handling . They have a mobile operations center and 20 roll-off containers or semitrailers , which can be brought to their place of use either with swap bodies , trucks (Mercedes-Benz) or by train. The vehicle fleet includes a mobile radiation measurement laboratory and three radiation measurement vehicles. Twelve Skylink radio probes can be placed on site to measure the local dose rate . For decontamination include a mobile decontamination system (MDA), two persons shower containers and cleaning machine "Alpha" is available. In order to penetrate into danger areas, the KHG has several radiation-hardened robots, including a heavy manipulator vehicle (SMF), manipulators “MF3” and “MF4”, and a radio-controlled caterpillar . The emergency vehicles have a special signal system , not all of them are labeled, but can still be recognized as belonging to the KHG by their dark brown paintwork with light brown stripes.

Infrastructure

The Infrastructure Department provides equipment for planning and managing operations. In particular, the people who are involved in rectifying the malfunction that led to the incident or accident can be provided with specialist information there.

Radiation protection

The radiation protection department equips assistants deployed inside the affected facility with radiation measuring devices. He also carries out radiation measurements inside and in the vicinity of the facility himself and examines employees, auxiliaries and civilians for possible contamination . To do this, he has devices for measuring the strength of ionizing radiation and for identifying radioactive substances .

decontamination

The decontamination department has showers for cleaning contaminated people and equipment. He also carries breathing apparatus and protective clothing to equip the assistants.

Remote handling

The remote handling department has several remote-controlled vehicles that can be equipped with video cameras and various machine tools in order to carry out manual tasks in contaminated areas and thus rectify faults in the nuclear facility.

Research and development programs

The KHG is or has been involved in several research and development programs, including:

  • Sub-projects of the research program "Research for Civil Security" of the Federal Ministry of Education and Research
    • Membership in the “ROBDEKON” consortium: As an industrial partner, the KHG is a member of the ROBDEKON consortium (robot systems for decontamination in hostile environments). It serves as a competence center for research into autonomous and semi-autonomous robot systems for decontamination in hostile environments and has been funded with 12 million euros by the Federal Ministry of Education and Research since 2018. The term extends until 2022. The skills and knowledge of the KHG are of interest to the consortium in connection with the decommissioning of German nuclear power plants and their dismantling using robot-based decontamination processes, as they have many years of experience in the field of person and material decontamination.
    • Collaboration in the ANCHORS project: KHG was involved in the Franco-German ANCHORS (Assisted Ad Hoc Networks for Crisis Management and Hostile Environment Sensing) project, which was about a new system for detecting the situation from a safe distance from the damage site with the help of robots equipped with sensors goes. The project ran from 2012 to 2015. The KHG received funding of 132,565 euros for sub-project 13N12208 "Development of the overall architecture, creation of a description of the operational scenario, modification of a remote-controlled two-track vehicle including integration of all necessary components". The KHG is itself a beneficiary of the project results because, according to its own statements, it operates a large number of functionally complementary remote-controlled air and ground systems, but cannot use them simultaneously and cooperatively due to various technical restrictions. The following scenarios were examined within the scope of the project: Incidents in nuclear power plants (plane crash on a nuclear power plant, venting in a nuclear power plant after failure of the energy supply), transport accidents with radioactive sources (derailment of a train with a Castor container, damage to a container with radioactive waste), incidents with radioactive material (industrial accident with material test sources , test sources in scrap).
  • As part of the EU framework program “ Horizon ”, the KHG participated in the project “Centauro”, which was estimated from 2015 to 2018, to develop a symbiotic human-robot system in which a human operator remotely controls a centaur-like robot with his whole body . The CENTAURO robot consists of a four-legged base and an anthropomorphic upper body. It is said to be able to move inside buildings and up stairs that are littered with debris and have partially collapsed.
