ASN Report 2018

T he Lille division regulates nuclear safety, radiation protection and the transport of radioactive substances in the 5 départements of the Hauts‑de‑France region. Hauts-de-France region In 2018, ASN’s carried out 111 inspections in the Hauts-de- France region, of which 21 were in the Gravelines NPP, 85 in small-scale nuclear activities and 5 in the transport of radioactive substances. ASN also carried out 12 labour inspection operations in the Gravelines NPP. During 2018, 5 significant events rated level 1 on the INES scale were notified by the Gravelines NPP. In small-scale nuclear activities, 4 events were rated level 1 on the INES scale, while 9 events concerning radiotherapy and brachytherapy treatments were rated level 1 on the ASN- SFRO scale and 1 concerning radiotherapy treatment was rated level 2 on the ASN-SFRO scale. ASN drew up one violation report in the exercise of its oversight duties. Gravelines nuclear power plant The Gravelines NPP, operated by EDF, is located in the Nord département on the shores of the North Sea, 21 km east of Calais and 15 km west of Dunkerque. The site is situated 30 km fromBelgium and 60 km from the United Kingdom. This NPP comprises six 900 MWe pressurised water reactors, representing a total power of 5,400 MWe. Reactors 1 and 2 constitute BNI 96, reactors 3 and 4 BNI 97 and reactors 5 and 6 BNI 122. ASN considers that the nuclear safety and radiation protection performance of the Gravelines NPP is in line with its general assessment of EDF performance. Improvements in operating rigour were observed in 2018. With regard to nuclear safety, the Gravelines NPP made progress in 2018 in the areas of reactor control and compliance with procedures. The site must nevertheless remain vigilant with regard to system configuring and enhancing the reliability of practices.
