Nuclear technology

Technical solutions across the entire plant life cycle

SIEMPELKAMP NIS Ingenieurgesellschaft supports operators of nuclear facilities and power plants from new construction and retrofit through operation and outages to shutdown and decommissioning. To this end, we combine engineering, decontamination, residual-material treatment, radiation protection, and nuclear physics with customer-specific machines and technical equipment.

In addition, we offer software and information systems, bolt-tensioning technology, as well as vibration diagnostics and condition monitoring. This gives you a coordinated way to access our services for different project phases and technical tasks.

Services for nuclear facilities and power plants

New construction, retrofit, and plant operation

We develop and implement technical solutions for the new construction, modernization, and retrofit of nuclear facilities. Depending on the project, we take on the planning, design, manufacturing, installation, and commissioning of customer-specific components and equipment.

Primary-system decontamination

We support the decontamination of primary and auxiliary systems with project-specific processes and technical expertise. We tailor planning and execution to the respective facility, its condition, and the operational requirements.

Shutdown and decommissioning

We support shutdown and decommissioning projects from planning through technical implementation. Among other things, we develop special-purpose machines, handling systems, and solutions for dismantling, segmentation, and packaging.

Residual-material and waste treatment

We plan and implement systems and components for the handling, sorting, treatment, and conditioning of radioactive residual materials and waste. The solution is tailored to the material, the process sequence, and the project-specific requirements.

Radiology, radiation protection, and nuclear physics

We support you with radiological, radiation-protection, and nuclear-physics tasks. This includes specialist consulting, calculations, measurement-data management, and technical services for operation, outages, shutdown, and decommissioning.

Engineering and project support

We support your projects from concept development through technical implementation. This includes, among other things, planning, support in the approval process, project execution, outage optimization, and technical documentation.

Overview of services

Technical systems & software

Software for operation and decommissioning

We develop software and information systems for operating, measurement, radiation-protection, and decommissioning data. The applications support structured work processes, traceable documentation, and project-specific evaluations.

Bolt-tensioning technology

We supply bolt-tensioning systems for the controlled tightening and loosening of large bolted joints on power-plant components. Our portfolio includes new systems, modernization, maintenance, spare parts, and technical adaptations of existing systems.

Vibration diagnostics and condition monitoring

We support the condition assessment of machines and plant components with vibration measurements, analyses, and condition-monitoring systems. This makes it possible to detect conspicuous operating conditions and prepare technical decisions on a more solid basis.

Discuss your technical task

Are you planning a retrofit, outage, shutdown, or decommissioning measure? Or do you need software, bolt-tensioning technology, or support for machine monitoring? Describe your facility, the project phase, and your technical task. We will assign your inquiry to the appropriate specialist department and coordinate the next steps with you.
