Flamanville EPR reactor pressure vessel
On 9th October 2018, ASN authorised the commissioning and operation of the Flamanville EPR reactor pressure vessel, subject to the performance of a test programme to monitor the thermal ageing of the steel in the residual carbon positive macro-segregation zone, plus specific inspections during operation of the facility.

Welding of the main steam transfer pipes of the Flamanville EPR reactor
ASN has informed EDF of the conditions for resuming certain welding operations on the main steam transfer pipes of the Flamanville EPR reactor. The welding operations involved are restricted to those performed using the "TIG orbital" process which enables high mechanical performance to be achieved.

Protection of the public, patients and workers in the field of nuclear activities
On 05 June 2018, two decrees concerning the protection of workers against the risks arising from ionising radiation and one decree containing various nuclear provisions were published in the Official Gazette. In particular, these decrees transpose the Council Directive 2013/59/Euratom of 5 December 2013 laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation. They more specifically modify the regulatory parts of the Labour, Public Health, Environment and Defence Codes, and thus supplement the regulatory oversight of certain nuclear activities

Radiation protection recommendations for the transport of radioactive substances
The inspections carried out by ASN, the French nuclear safety authority, reveal that the risk of exposure to ionisation radiation is not sufficiently integrated in the preventive measures relating to the transport of radioactive substances. Yet some transport activities have significant radiation protection implications, particularly for the workers due to their close proximity to the packages. The annual dose for a driver transporting radiopharmaceuticals can thus reach 14 millisieverts per year (mSv/year)1, the maximum regulatory value being 20 mSv/year.

Flamanville EPR reactor: ASN inspection on 10th April 2018
On 10th April 2018, ASN carried out an inspection on the Flamanville EPR reactor construction site to examine how the welds on the main secondary systems were checked following EDF’s discovery of welding flaws, which had not been detected during the manufacturing checks.
