Refurbishment / enhancement or demolition of Nuclear structure is a controlled activity that involves care and adherenceto rules and safety regulation. Risk mitigation is the key work and controlled decom (decommissioning) involves drilling or sawing of complex heavily reinforced concrete or pure steel structures in a radioactive environment . These activities could potentially be done with or without coolant utilizing synthetic diamond technologies.
Below we show you the projects in which the employees of siegenthalerconsulting GmbH were significantly involved in the past.
Stationary Portal Diamond Wire Saw Sytem for NPP Decommissioning
- Cutting of large steel components in the decommissioning of a nuclear power plant
- Underwater application
- Vertical and horizontal cutting possible
- Guided on rails above and below
- Closed diamond wire loop (no wire connector necessary)
Gallows Diamond Wire Saw System for NPP Decommissioning
- An 8 m high cooling cylinder of a reactor is sawn vertically into 12 segments
- Dry diamond wire sawing in pure steel
- Remote-controlled gallows diamond wire saw system
- The diamond wire is driven by a standard diamond wire saw drive unit
- The 8 m long segments are cut into 1 m long pieces with a mobile diamond portal wire saw
Mobile Portal Diamond Wire Saw System for NPP Decommissioning
- A heat exchanger is sawn into pieces
- Dry diamond wire application
- The diamond wire is driven by a standard diamond wire saw drive unit
- Closed diamond wire loop (no wire connector necessary)
- The sawing advance feed is controlled remotely via the control panel of the drive unit
