The environmental protection performance, however, is considered to be below the EDF plant average. With regard to nuclear safety, ASN considers the performance of the NPP to be satisfactory. However, ASN still observes shortcomings in the licensee’s organisation for managing deviations, with numerous findings not being adequately characterised or traced.

This event revealed deficiencies in the planning of maintenance operations and the management of reactor state changes. An inspection will be organised on these themes in 2020. Lastly, ASN considers that particular attention must be paid to the preparation of operational control activities in order to improve the quality of the documentation supporting operation of the facilities and the rigour with which the instructions are applied. With regard to radiation protection, the forward-looking personnel radiological exposure targets were met during the ȸƺƏƬɎȒȸ ژא ȒɖɎƏǕƺِ RȒɯƺɮƺȸً Ɏǝƺȸƺ Əȸƺ ƳǣɀȵƏȸǣɎǣƺɀ ǣȇ Ɏǝƺ ɯƏɵ Ɏǝƺ radiation risks are taken into account. The practices witnessed by inspectors during worksite inspections and the increasing number of significant radiation protection events still reflect a lack of rigour. ASN underlines the need for outside contractors to be better informed of the radiological risk. In the area of environmental protection, ASN observes significant progress in the managements of gases that deplete the ozone layer. Shortcomings have nevertheless been noted in the grasp of the regulations concerning waste management. ASN does however underline the quality of operation of the treatment plant. The inspections relating to worker safety reveal shortcomings in the prevention of chemical risks in the facilities in operation, in the prevention of electrical risks, and in work at height on the construction sites, particularly that of the ultimate backup diesel-generator sets.

Important start-up test phases have also taken place, with the performance of the hot tests, which enable the functioning of the nuclear steam supply systemand the associated auxiliary systems to be tested under the nominal temperature and pressure conditions. ASN conducted several inspections focusing specifically on these operations, including one 3-day tightened inspection on site. ASN underlines the mobilisation of resources and the marked improvement in EDF’s organisation for the start-up tests. EDFmust nevertheless supplement the demonstration of representativeness of the tests performed with respect to the test procedures, in particular through better command of the instrumentation and control configuration and tests carried out on a temporarily modified installation. Improvements are also expected in the utilisation of the accrued experience feedback and the implementation of the resulting corrective actions. ASN also inspected the organisation implemented by EDF for the quality review of the EPR reactor equipment.

ASN considers that EDF must substantially supplement its complementary inspections programme, particularly as regards equipment other than pressure equipment. Greater rigour is also required in the implementation of this programme. This review has nevertheless already disclosed a number of deviations that EDF must address appropriately. EDF must also ensure that a strategy is applied for the conservation, maintenance and testing of the equipment and structures present on the worksite until the reactor is commissioned. ASN inspected EDF’s organisation for the protection of the environment, in particular for the integration of ASN resolutions א ׎׏ ٮ!(ٮז ׎ ژחבה ƏȇƳ א ׎׏ ٮ!(ٮז ׎ גה ׎ ژ Ȓǔ ׏ ژח hɖǼɵ א ׎׏ ژז ȸƺǼƏɎǣɮƺ 70 ASN Report on the state of nuclear safety and radiation protection in France in 2019 REGIONAL OVERVIEWOF NUCLEAR SAFETY AND RADIATION PROTECTION NORMANDIE
