Hovedavrusningen

Hovedavrusningen refers to the main decommissioning phase of a nuclear facility. This process involves the systematic dismantling of radioactive components and structures, along with the decontamination of the site. The primary goal of hovedavrusningen is to reduce the radiological hazard to a level that allows for the site to be released for unrestricted or restricted use.

The process typically begins after the operational life of the nuclear facility has ended and any spent nuclear fuel has been removed and safely stored or reprocessed. Hovedavrusningen is a complex and lengthy undertaking, often spanning many years, and requires meticulous planning and execution. Safety is paramount throughout, with strict protocols in place to protect workers, the public, and the environment from radiation exposure.

Key activities within hovedavrusningen include the characterization of radioactive waste, its segregation, treatment, and packaging for disposal. Structures and equipment that have become contaminated are carefully dismantled, often using remote handling techniques to minimize human exposure. Decontamination of surfaces and remaining infrastructure is also a critical step.

The ultimate aim is to achieve a state where the residual radioactivity on the site is below predetermined clearance levels. Regulatory bodies oversee the entire process to ensure compliance with safety standards and environmental protection regulations. Successful completion of hovedavrusningen signifies the end of the nuclear lifecycle for a particular facility.
