ASN Report 2018

BRETAGNE REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION During 2018, EDF continued decommissioning of the Effluent Treatment Station (STE). The basement demolition work, which began in August 2016, was completed in early 2018 due to various work site contingencies. EDF then started the operations to remove the polluted soil situated beneath the STE, in accordance with the soil management plan approved by ASN in April 2018. The partial decommissioning operations were not yet completed on 28 July 2018. Moreover, in accordance with the amending Decree of 16 November 2016, EDF submitted the complete decommissioning file for the reactor in July 2018. This file is currently being examined by ASN. Alongside this, EDF finalised the worksite teardown operations for the reactor containment heat exchanger decommissioning site after the fire that occurred in September 2015. ASN considers that the licensee conducted this work in compliance with the safety and radiation protection requirements. In 2018, the licensee also started arrangements and the work to render secure the reactor building with a view to preparing the operations to take samples from the reactor block. These sampling operations were subject to the prior consent of ASN through a resolution of 21 August 2017. EDF has submitted an application file which is currently being examined by ASN. ASN considers that the licensee shows rigour and transparency in its handling of the malfunctions and deviations that occur on its site. The management of waste, particularly in the storage areas situated within the reactor containment, and compliance with regulatory requirements need to be improved. 40  ASN report on the state of nuclear safety and radiation protection in France in 2018
