Nuclear Technology - Safety through System Expertise

• Qualification of packaging for radioactive material

  The challenge: Safe transportation even under extreme conditions

  An international customer needed a new packaging solution for highly radioactive materials - designed for maximum safety even under the most severe accident conditions. In addition to the strict IAEA specifications (SSR-6), additional national requirements had to be met. Proof of integrity under worst-case scenarios was particularly critical:

  • Impact from a great height

  • Extreme heat (fire exposure)

  • Mechanical penetration

  • High water pressure at depth

  We were looking for an experienced partner with the necessary test infrastructure and interdisciplinary expertise - for safe and efficient approval.

   

  Our solution: a customized test campaign

  IABG developed a customized test strategy: physical tests were combined with computer simulations to assess load limits realistically and efficiently.

  • Drop test from a height of 9 m: proof of mechanical resistance on an unyielding impact target

  • Thermal test at > 800 °C: Testing the containment of radioactive substances when exposed to fire

  • Penetration test: 500 kg projectile on the weakest point to assess punctual resilience

  • Water immersion test: Tightness under 15 m water depth

   

  The result: approval faster than planned

  Thanks to the combination of simulation, targeted tests and close coordination with the approval authorities, the entire process was significantly accelerated.

  ✅ Planning reliability: the combination of simulations and physical tests meant that time-consuming night tests could be avoided.

  ✅ Efficiency: Smooth project management and coordination with authorities

  ✅Safety: Minimum requirements exceeded several times over

• Dismantling Niederaichbach NPP

  As part of the decommissioning of the Niederaichbach nuclear power plant, IABG supported the planning, approval and implementation of the mechanical dismantling of metallic components. We accompanied the project through all phases - from the concept review to the final clearance measurement of the affected building structures.

  Initial situation

  Proof of suitable dismantling technology was required for the safe and license-compliant decommissioning of the KKN. In addition to the manufacture and assembly of the systems, testing, acceptance and quality assurance documentation also had to be ensured.

  
  Our services

  • Concept and planning review of the planned dismantling technology

  • Preparation of a partial report in accordance with the specifications from the safety report

  • Carrying out preliminary tests and approval for production

  • Technical inspections and acceptance tests at the manufacturing plant (machine technology and control system)

  • Supervision of assembly and test acceptance on site at KKN

  • Technical dismantling support up to clearance measurement

  • Supplementary quality checks and documentation

  
  Results and added value

  IABG acted as an independent technical expert and supported the dismantling technology used throughout the entire course of the project - from the initial concept to the end of use. Our systematic testing and documentation work ensured a safe, regulatory-compliant dismantling process.

   

  

• Development of a remote handling system (HMS)

  Specialized, remote-controlled manipulator systems are indispensable for nuclear dismantling projects or operations in highly contaminated areas. On behalf of Kerntechnischer Hilfsdienst GmbH (KHG), IABG has developed a high-performance, modular remote handling system (HMS) that works reliably even under extreme environmental conditions.

  Based on a standard industrial small excavator, the HMS has been fully modified to be suitable for radiation and equipped with numerous tools - from hydraulic manipulators to concrete cutters, grabs and scrap shears. It is controlled by cable or radio, and monitored and remotely controlled via a comprehensive video and sensor system.

  Special technical features:

  • Application range: -40 °C to +55 °C, dose rate up to 100 Gy/h

  • Modular design for flexible tool integration

  • Wading capability up to 550 mm, climbing capability 29°

  • Protection of critical components through containment with lead shielding

  • Communication via redundant signal paths (LAN/WLAN)

  • Conformity with safety-related development standards (e.g. IEC 61508)
