Chooz A reactor undergoing decommissioning
The preparatory work for the decommissioning of the
ChoozA reactor vessel continued. The reactor cavity gates
were dismantled and the pressuriser, dismantled in2013,
was removed.
With regard to the environment and nuclear safety, ASN
considers that the decommissioning operations are
being carried out satisfactorily. Vigilance is nevertheless
required in the preparation of the activities, particularly
in the management of the interfaces between the various
contractors on the jobandon the verificationof the electrical
networks.
In the area of radiationprotection, the actions deployed in
2014 to improve themonitoringof outside contractors have
borne fruit. Although the volume of activities involving
riskswas lower than in the preceding years, ASNconsiders
that the radiation protection results are satisfactory. The
outside contractor training and awareness-raising actions
must be maintained.
1.2 Radiation protection
in the medical field
Radiotherapy
ASN inspected six of the twelve centres in 2015. These
inspections confirmed the positive trends regarding
the deployment of quality management systems. The
actions must still be continued in some cases for
the organisation of the medical physics organisation
plans and the updating of the radiotherapy process
risk studies to integrate experience feedback, among
other things.
Interventional practices
Continuing the actions which have been engaged since
2009, ASN performed eight inspections in operating
theatres in 2015. Highly contrasting situations have been
observed, most of which require measures concerning
the radiation protection training of the personnel and
the technical verifications of the machines. Progress
is also still required in the tracking and analysis of
doses delivered to patients, through more systematic
defining and optimising of the intervention protocols
(see chapter 9, point 1.1.2).
