ASN Report 2018

NORMANDIE REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION the review and the conformity check. This weakness results in an insufficient level of control of the action plan and could be prejudicial to its implementation over the long term. ASN analysed the admissibility of the periodic safety review report for BNI 118 submitted by Orano Cycle in November 2017. It considered it generally satisfactory with regard to the requirements of the Environment Code, but nevertheless requested additional information concerning the conformity check of the activities important to protection, and the examination of the protectionmeasures with respect to fire, the tornado hazard, and the dimensioning of the emergency management resources. The safety review report is currently being examined. Management of the condition of the evaporation concentration containers ASN continued to verify implementation of the provisions of ASN resolution 2016-DC-0559 of 23 June 2016 relative to the fission product evaporators, issued further to the finding of a rate of corrosion exceeding that considered in their design. The regular assessments of the results of the monitoring actions on these equipment items and of the regulatory inspections carried out by the licensee and communicated to ASN show that the thickness of evaporator 4120‑23 in the T2 facility, identified as being the most affected by corrosion, is close to theminimum required thickness.
