ALE Goldhofer SPMT (Inferred) at Dungeness B Nuclear Power Station Decommissioning

Dungeness, Kent, UK · 2021-Ongoing (Decommissioning phase)

The judgement call

Account-gated at launch

The decommissioning of Dungeness B nuclear power station involves the dismantling and removal of large, heavy, and potentially contaminated structures. While direct evidence of ALE (now Mammoet) or Goldhofer SPMTs being specifically used at Dungeness B is not readily available in public search results, such equipment is routinely employed in nuclear decommissioning projects globally due to its capacity and precision in handling oversized loads. Their use would be critical for the safe and efficient removal of reactor components and other heavy plant.

Key engineering challenges

Safely and precisely moving large, potentially radioactive components within a nuclear site. - Planning and executing complex transport routes to minimize risks. - Adhering to stringent nuclear safety and environmental regulations during decommissioning.
