ASN Report 2022

stored within the bounds of the Cadarache DBNI and which originally came from the Pégase pool. This request led ASN to initiate a process to amend resolution CODEPCLG-2017-006524 amended relative to the removal from storage operations on the Pégase facility. This amendment will be subject to public consultation in 2023. ASN considers that the nuclear safety and radiation protection of the Pégase and Cascad facilities for 2022 is on the whole satisfactory. ASN found the worksite organisation to be satisfactory. The actions resulting from the periodic safety review are followed correctly. ASN will nevertheless remain attentive to the consistency between the baseline requirements applicable to the facilities and the progress of the decommissioning preparation operations, as well as to the management of fuel storage capacity saturation in the Cascad facility. Cabri research reactor – CEA centre The Cabri reactor (BNI 24), created on 27 May 1964, is intended for conducting experimental programmes aiming to achieve a better understanding of the behaviour of nuclear fuel in the event of a reactivity accident. The reactor has been equipped with a pressurised water loop since 2006 in order to study the behaviour of the fuel at high combustion rates in accident situations of increasing reactivity in a PWR. Since January 2018, the CEA has been conducting a programme of tests called “CIP” (Cabri International Program), which began in the early 2000’s and necessitated substantial modification and safety upgrading work on the facility. ASN examined the safety of the reactor taking into consideration the action plan and the compensatory measures proposed by the CEA to deal with the two leaks reported in September 2020 and February 2021. It authorised the resumption of the CIP programme tests by resolution CODEPMRS-2022-022299 of 9 June 2022, after the repair of the fault found on the “core water” system. The licensee has undertaken to provide feedback before 31 October 2023 on the implementation of the compensatory measures which consist in reinforcing monitoring of the condition of the faults still present on the hodoscope. Decree 2022-1108 of 2 August 2022 amending Creation Authorisation Decree 2006-320 of 20 March 2006 has also been signed by the Minister responsible for nuclear safety, further to ASN’s approval. This Decree amendment extends the scope of activities of the facility to include the performance of irradiation tests on electronic components. ASN considers that the level of nuclear safety and radiation protection of the facility is on the whole satisfactory. The licensee has duly taken into account and dealt with some of the faults detected on the various reactor equipment items. Authorisation requests are currently being examined to address the residual defects of the hodoscope and therefore restore a completely normal situation. In this context, the licensee has taken into account ASN’s requests for additional information on reactor operational control in accident situations. Rapsodie research reactor – CEA centre The Rapsodie reactor (BNI 25) is the first sodium-cooled fast-neutron reactor built in France. It operated from 1967 to 1978. A sealing defect in the reactor pressure vessel led to its final shutdown in 1983. Decommissioning operations were subsequently undertaken, but have been partially stopped further to a fatal accident in 1994 during the washing of a sodium tank. At present the core has been unloaded, the fuel evacuated from the installation, a large part of the fluids and radioactive components have been removed and the reactor vessel is contained. The reactor pool has been emptied, partially cleaned out and decommissioned and the waste containing sodium has been removed. The Decommissioning Decree was signed on 9 April 2021. This Decree sets a new perimeter for the facility and regulates, until 2030, the next phase of reactor life, consisting in treating the sodium from the reactor and introducing air into the tank containing it. An authorisation application file will be submitted to ASN for the reactor vessel washing operation. The subsequent decommissioning operations, such as decommissioning of the reactor block or of the civil engineering structures, shall be covered by an update of the decommissioning file.
