Flamanville 3 project, Communication NEWSFLASH EPR FLAMANVILLE 3 JULY 2014 Reactor building Welding work on the first loop of the main primary circuit has been in progress since June... Aerial view- May 2014 Introduction of a" cross over" leg Introduction of a" cold" leg Reactor building The main primary circuit comprises 4" loops", each consisting of three primary legs (see diagram.

Aerial view- May 2014 Reactor building Removal of the reactor vessel transport plug and installation of an access platform in order to prepare for welding work on the main primary circuit. Aerial view- May 2014 Reactor building Installation of a heat exchanger forming part of the chemical and volume control system (CVCS.

EDF submitted to ASN a technical file presenting the procedures for repairing and upgrading the main secondary circuit welds. which had showed deficiencies with respect to the break preclusion requirements.

Communication NEWSFLASH EPR FLAMANVILLE 3 JUNE 2014 More than 2800 workers take part in the 9th industrial safety event, focusing on industrial safety fundamentals Reactor building First welding operations on the main primary circuit, using an orbital welding machine. The welds will connect the" cold" leg to the reactor vessel and the reactor coolant pump casing.

What' s more, in spring 2018 (as we explained at a press conference in July 2018,) EDF detected quality drift in some of the welds of the main secondary circuit at Flamanville and started additional inspections of the entire circuit... which is now complete apart from the main secondary circuit and is now entering the hot functional test phase.

using remotely operated robots, following ASN (2) agreement Pending ASN ruling on the treatment of 3 nozzles of the main primary circuit New nuclear Submission by EDF and the nuclear industry. to the public authorities, of their contribution to the programme to build 3 pairs of new ERP2 reactors in France Small Modular Reactor.

Other welds In addition, the technical investigation into reworking the welds located in the Main Secondary Circuit (Circuit Secondaire Principal) with quality shortfalls and / or not complying with the requirements of the break preclusion reference document defined by EDF is ongoing... However, repair work on other welds of the Main Secondary Circuit and other activities underway on the worksite are also creating additional risk to the schedule and the target cost on completion for the reactor.

Regarding Flamanville 3, repair operations on the eight penetration welds of the main secondary circuit are underway following the ASN' s' approval for the intervention by remotely operated robots. In June, we submitted to the ASN a summary of our studies on the handling of the nozzles on the main primary circuit.
