ASNnoted thepersonnel’s higher level
of expertise regarding the explosion
risk but considers that EDF must
devote greater effort to training and
exercises for the response crews. ASN
doeshoweverconsiderthatinsufficient
account is takenof the lessons learned
from events on all the reactors.
ASN considers that the organisation
in place on the sites for managing
skills, qualifications and training is
on thewhole satisfactory and that the
management processes are generally
well-documented and coherent.
Generally speaking, the training
programmes are run satisfactorily.
Nonetheless, the range of training
proposedby certain sites is not always
adaptedrapidlyenough.Furthermore,
the persons concerneddonot always
receive the scheduled training.
In general, EDF devotes significant
investment to hiring and training,
in order to anticipate the necessary
renewal of skills. Given the expected
departures and the work to be done
by EDF in the coming years, ASN
considers that EDFneeds to continue
its efforts with regard to hiring and
training.
ASN considers EDF’s approach for
improved integrationof organisational
andhuman factors in the engineering
departments to be pertinent.
Nonetheless, EDF must continue
with its efforts in order to achieve
the expected effects.
ASN observes that the collective
dosimetry on all the reactors was
slightlydown in2015by comparison
with 2014 and that the regulation
annual limit for external whole-body
dosimetry was never exceeded in
2015. ASN notes that the collective
dose has been stable for about ten
years now, reflecting the increased
volume of maintenance work in
controlled areas, combined with
continued optimisation efforts. ASN
considers that weaknesses remain in
the control of industrial radiography
operations and that of the dispersion
of contamination inside the reactor
building continues to be inadequate,
owing toworksite containment faults
or a lackof signallingof contamination
levels.
ASNconsiders that EDF’s organisation
for thenuisance and impact control of
NPPsontheenvironmentissatisfactory
on most sites and is progressing,
more specifically with improved
assimilation of the regulations.
Monitoringof dischargeobjectives and
integration of operating experience
feedback remain an area requiring
progress. Waste management is on
thewhole progressing but could still
be improved.
TheASNassessments of eachNPP are
detailed inchapter 8of the report. The
Penly, FessenheimandSaint-Laurent-
des-Eaux sites stand out positively
in this general assessment, while
Cruas and Gravelines are however
under-performing.
Manufacturing of pressure
equipment
ASN observes that the justifications
anddemonstrations provided by the
manufacturerswith regard tonuclear
pressure equipment regulations are
still regularly unsatisfactory. As of
the first half of 2015, EDF andAreva
therefore tookorganisationalmeasures
to improve their practices and bring
them into line with the regulatory
requirements. ASN considers this
approach to be a positive one and
will be attentive to ensuring that it is
seen through to completion.
Outlook
In 2016, ASN will issue a ruling on
the orientation of the generic studies
to be carried out in preparation for
the fourth periodic safety reviews of
the nuclear reactors, after consulting
the public on the draft additional
requirements to be sent to EDF
concerning its design andverification
programme.
Monitoring the implementationof the
material andorganisationalmeasures
prescribed following the Fukushima
Daiichi accident remains a priority for
ASN. In 2016, ASN will be heavily
involved in examining the design,
constructionandoperatingprovisions
adopted by EDF.
2016 will also see continued
examination of the commissioning
authorisation application for the
Flamanville 3 EPR reactor. ASN
will examine the detailed design
of the reactor and will monitor the
construction and the preparation
for the start-up tests. It will examine
the file that Areva intends to submit
concerning the reactor vessel anomaly.
In 2016, ASN will continue the
extensive work it initiated in 2015
with themanufacturers, licensees and
organisations it approves, regarding
the drafting of professional baseline
requirements and conformity
evaluation baseline requirements.
Finally, ASN will ensure that the
ongoing reorganisation of the
industrial players takes account of
the safety issues and that the safety
improvementmeasures alreadyunder
way are continued.
