This inquiry consists in collecting and analysing all useful information, without prejudice to any judicial inquiry, in order to determine the circumstances and the identified or possible causes of the event, and draw up the appropriate recommendations if necessary.

The second concerned non- compliance with the general operating rules when draining the primary system on the Golfech NPP. The last was a “generic event” affecting the NPPs of Saint-Laurent-des-Eaux, Civaux, Paluel and Gravelines and concerned a risk of damage of the emergency diesel generating set lines owing to their potential contact with civil engineering structures in the event of an earthquake (see box in chapter 10).

The second concerned a member of a nuclear medicine unit who on a single occasion exceeded the ionising radiation occupational exposure limit value defined by the Labour Code. 2. This scale is designed for communication with the public in comprehensible, explicit terms, concerning radiation protection events leading to unexpected or unforeseeable effects affecting patients undergoing an external radiotherapy medical procedure. As indicated earlier, these data must be used with caution: they do not in themselves constitute a safety indicator. ASN encourages the licensees to notify incidents, which contributes to transparency and the sharing of experience. The distribution of significant events rated on the INES scale is specified in Table 6.

Likewise, significant events concerning the environment but involving non-radiological substances are not covered by the INES scale. Such events are classified as “out of INES scale” events.

To ensure that its inspection work is transparent, ASN informs the public by placing the following on its website asn.fr : Ҋ its resolutions and decisions; Ҋ inspection follow-up letters for all the activities it inspects; Ҋ approvals and accreditations it issues or rejects; Ҋ incident notifications; Ҋ the results of reactor outages; Ҋ its publications on specific subjects. 152 ASN Report on the state of nuclear safety and radiation protection in France in 2019 ׎ ٲ ב REGULATION OF NUCLEAR ACTIVITIES AND EXPOSURE TO IONISING RADIATION
