Regulatory oversight of facility modifications

Regulatory control of facility modifications

STUK regulates modifications from design to implementation.

Different modifications are carried out in nuclear facilities. The purpose of these modifications may be to improve safety, renew ageing systems and equipment, facilitate operations or maintenance in the facility or to enhance energy production. STUK inspects plans for extensive and safety-significant modifications and supervises the modifications based on documentation submitted by the licensee as well as inspections on site or at manufacturers.
