In 2015, in response to several requests from ASN, ILL
proposed putting in place an integrated management
system that meets the requirements of the BNI regulations,
and revamping its safety organisation to make it more
independent.
In response to the ASN compliance notice, ILL submitted
requests to be granted particular conditions for application
of Title III of the Decree of 13th December 1999 relative
to nuclear pressure equipment for the 22 equipment items
displaying deviations from regulations. Each of these files
describes the proposed measures to compensate for the
verifications that cannot be performed on account of the
particularities of the RHF equipment. After analysing the
proposals, ASN defined these particular arrangement
conditions through two resolutions in March 2015.
The Activated waste packaging and interim
storage installation (Iceda) at Bugey
The purpose of the Iceda facilitywill be to process and store
activated waste from operation of the EDF installations
and from the decommissioning of first-generation reactors
and the Creys-Malville NPP.
After a break of several years, work on the construction
site resumed fully in early April 2015. After completing its
inspections, ASN considers that the restart was managed
with rigor and that the worksite is well kept. The level
of surveillance put in place by EDF is appropriate for
the risks.
Ionisos irradiator in Dagneux
The Dagneux irradiator – BNI 68 – operated by the
company Ionisos, displayed a satisfactory level of safety
in 2015. The pool water treatment whosemalfunctioning
had been detected by ASNduring an inspection in 2014,
was brought back into compliance with the installation’s
baseline safety requirements.
The periodic safety review of the installation will be
examined in 2016, following which ASN will state its
position on the continuation of its operation.
EDF BCOT - Operational Hot Unit on the Tricastin site in Bollène
On completion of its inspections, ASN considers that the
level of safety of the BCOT is satisfactory. In 2015, ASN
verifiedperformance of the tests prior to starting cutting up
the control rod drivemechanisms for packaging as waste.
CERN - Accelerator and Research Centre (Geneva)
Following the signing of an international agreement
betweenFrance, Switzerland andCERNon15thNovember
2010, ASN and the OFSP (Swiss Federal Office of Public
Health) - the Swiss radiation protection oversight body
- are contributing to the verification of the safety and
radiation protection requirements applied by CERN.
The joint actions concern transport, waste and radiation
protection.
ASN and the OFSP have thus approved the site’s nuclear
wastemanagement study and the safety case of a new linear
accelerator built on the CERN site and called Linac 4.
A joint inspection of this linear accelerator was carried
out with the Swiss authorities in 2015.
A protocol for notifying and sharing information
concerning significant events and their rating on the
INES scale between the organisations (CERN, ASN,
OFSP) has also been drawn up. CERN made its first
significant event notification in 2015, which is positive
with regard to transparency and the improvement of
experience feedback.
1.2 Radiation protection
in the medical field
Radiotherapy
ASN carried out 11 inspections in the 22 radiotherapy
centres in the Rhône-Alpes andAuvergne regions in 2015.
ASN’s inspections focused inparticular on themanagement
of treatment safety and quality, preparation of treatments,
control of patient positioning during treatment and
implementation of the professional practices evaluation
process. Particular attentionwas also devoted to centres
that implement innovative treatment technologies, those
whose staffing levels are considered potentially vulnerable,
and those that are behind schedule with implementation
of the quality assurance system.
The results of these inspections show that all centres have
taken organisational steps since 2009 to implement a
quality assurance approach to improve the delivery of
treatments to patients. These quality assurance systems
are now increasingly used on a daily basis by all the
personnel in the centres as part of a process for continuous
improvement of quality of medical care.
The radiotherapy centres have all put in place a system
for detecting significant events. In the majority of cases,
these events concern a patient over one or a few treatment
sessions and have no expected clinical consequences.
ASN was notified of 23 events in 2015 and is making
sure that the centres concerned draw the appropriate
lessons from these events.
