Serviceability of 900 MWe reactor pressure vessels

In order to take into account pressure vessel aging and possible changes in available knowledge and information, the demonstration of the serviceability of NPP pressure vessels is regularly updated by EDF and examined by the French Nuclear Safety Authority (ASN). In anticipation of the decisions to be taken regarding the continued operation of each 900 MWe reactor after the third ten-year inspection (VD3), EDF has submitted a justification documents for technical evaluation by the ASN with the technical support of the French Institute for Radiological Protection and Nuclear Safety (IRSN).

ASN undertakes review of safety options for the new ATMEA 1 reactor

Several countries are planning to build new nuclear power plants. In this context, ATMEA, the joint venture formed by French industrial group, AREVA, and the Japanese industrial group, Mitsubishi Heavy Industries (MHI), called upon ASN to carry out a review of the safety options[1] for a new Pressurized Water Reactor known as ATMEA1. According to ATMEA, this medium-output reactor (1100 MWe) is mainly for the export market.

Instrumentation and control system of the Flamanville 3 EPR

In order to improve the robustness of the instrumentation and control (I&C) system [1] of the EPR reactor, ASN asked EDF to modify one of the reactor’s control platforms. EDF had already considered this modification towards the end of 2009 in response to ASN’s request on 15 October 2009.

Quarterly assessment of radiotherapy events

Twenty-one events, classified as level 1 on the ASN-SFRO scale, were reported between 1 April and 30 June 2010. Although these events are not expected to have any impact on patients’ health, they are analysed to see if any lessons can be learnt from them (particularly as regards organisation) and to avoid any recurrence.

International meeting on national radioactive waste management organisations

An international meeting was held in Paris from 7 to 9 June 2010 on the establishment of a radioactive waste management organisation in each country. Organised by the International Atomic Energy Agency (IAEA) with the support of ASN, DGEC and ANDRA, the meeting brought together around 110 participants from more than 50 countries.

the Tritium White Paper

The Tritium White Paper is the fruit of work by two broad-based working groups set up at ASN's initiative to review the behaviour of tritium in the environment and the evaluation of the biological impact of tritium on humans, in the wake of publications by British environmental and health agencies on the subject.

New nuclear reactors built around the world

One of the major ASN concerns is to achieve harmonization based on the best nuclear safety and radiation protection levels worldwide. We do not want a “two-speed” safety and we continue to promote at European and international levels safety objectives that take into account the lessons learnt from Three Mile Island, Chernobyl and September 11, 2001 events. In the event of proposals to export nuclear reactors which do not meet these safety objectives, ASN will not hesitate to declare that such reactors could not be built in France.
