Fort Calhoun Station Decommissioning and Demolition Project Reactor Vessel Segmentation

The Fort Calhoun Nuclear Generating Station (FCS) commissioned in August 1973 was shut down in October 2016. The station was powered by a pressurized water reactor with a name plate capacity of 502 MW. The station is located between Fort Calhoun and Blair in Nebraska, USA. Following the shut-down the decommissioning of the power station started. Siempelkamp NIS was tasked with the segmentation of the Reactor Vessel (RV). The RV was roughly 10 meters high and had a diameter of about 4 meters. The 203 metric ton heavy vessel was cut into 43 segments using an oxy-fuel cutting system. The paper focuses on the whole execution phase of the project.
