has been reused, and then clean out the areas in which
the radiological anomalies are incompatible with land
use. In this context, at the end of 2014 Areva identified
through aerial surveys followed by ground verifications,
58 sites in municipalities of the Nièvre and Saône-et-
Loire
départements
where mining waste rock has been
deposited. This inventory was supplemented in 2015 by
a radon measurement campaign in the buildings of the
municipalities concerned. Arevamust propose solutions
for remedying the radiological anomalies resulting from
the reuse of mining waste rock to the State. ASN will
inform the prefectural authority of its opinion on Areva’s
proposals in 2016.
ASN is particularly attentive to the monitoring of two
sites situated in Saône-et-Loire on the municipalities
of Gueugnon and Issy l’Evêque, because they contain
radioactive substances which are not mining waste rock.
In Issy l’Evêque, waste fromnuclear installations andmine
tailings have been stored in a former uraniummine (Bauzot
site). A prefectural Order of 7th April 2011 instructed
Areva to improve the knowledge and monitoring of the
radioactive substances stored on the site. In 2015, ASN
assisted the prefectural authority by having IRSNappraise
studies carried out by Areva on the basis of samples
taken from the site in 2013. The prefectural authority
asked Areva to supplement the assessment of radioactive
substances present on the site and the monitoring of the
site environment.
InGueugnon, waste froma uraniumore processing plant
which operated there between 1955 et 1980 is stored
in an ICPE. As part of the procedure for listing mining
waste rock deposit sites, Areva discovered the presence
of mine tailings, which constitute radioactive waste, in
five sites near the ICPE. Additional investigations have
been undertaken to obtain an exhaustive assessment of
the radiological condition of the sites, involving taking
soil samples and radonmeasurements in buildings. Areva
must present the prefectural authority with solutions to
remedy the situation.
2. ADDITIONAL INFORMATION
2.1 Informing the public
Press conference
On 15th June 2015, ASN held a press conference on the
status of nuclear safety and radiation protection in the
Bourgogne and Franche-Comté regions.
Valduc (Seiva)
A structure providing a forum for discussion and
information on the CEAValduc centre (Seiva) has existed
since 1996. This structure, which is funded chiefly by
the
conseil général
(General Council) of the Côte-d’Or
and ASN, informs the public of the impact of the Valduc
centre’s activities, insofar as the subjects addressed do not
concern confidential aspects covered by its classification
as a Secret Basic Nuclear Installation. ASN took part in
the annual general meeting of Seiva which was held on
3rd February 2015. Seiva undertook the supplementing
of its multi-year environmental monitoring dashboard in
2015 by taking measurements in the sediments.
2.2 The other notable events
Emergency situation preparedness
On 1st October 2015, the Dijon division took part in
the national emergency exercise simulating a radioactive
substance transport accident in Saône-et-Loire on the
A6 motorway. The aim of this exercise was to verify the
response of a non-nuclearised
département
in the event of
such an emergency and to test the prefecture’s response to
media pressure and its interfaces with the national level
of the nuclear authorities. The exercise pinpointed areas
inwhich the management of such emergency situations
can be improved, such as the involvement of themayors,
triggering and broadcasting the alert, and the method of
interchange between the stakeholders.
On 10th December 2015, the Dijon divisions took part
in the local emergency exercise organised by the Nievre
prefecture to test part of the departmental organisation
for the distribution of iodine tablets should the “Orsec”
(national emergency response) plan be triggered by
the national authorities. The exercise allowed the
implementation of some of the measures provided for
in the departmental plan for the distribution of iodine
tables to the population, and highlighted the need to
supplement the local safeguard plans.
Management of emergency situations
The Dijon division assisted the prefectural authorities in
the management of the following emergency situations:
•
On 23rd July 2015, further to the discovery of a source
of caesium and traces of uranium contamination in a
private individual’s home in Yonne, ASN asked the
CEA (French Alternative Energies and Atomic Energy
Commission) to ensure the radiological remediation of
the site and IRSN to subsequently verify that all added
radioactivity had been removed.
•
On 16thOctober and 7th November 2015 in the Jura,
following the discovery of an object containing natural
uranium in a station of the
Gendarmerie
and an object
containing radium in a private individual’s home. These
objects were recovered by Andra.
