and formalising the storage area operating instructions.
BNI 49must also be vigilant with regard to themanagement
of decommissioning wastemovements and storage areas
which have led to the notification of two significant events.
The centre’s organisation of transport management was
considered generally satisfactory.
The CEA has also again notified events concerning the
monitoring of gaseous discharges from the installations.
One event in particular revealed that the steps taken by
CEA to ensure compliance with the resolutions regulating
the discharges from the centre had not been carried out
exhaustively and with the necessary rigour.
Operation of the BNIs
ASN considers that the physical upgrades necessary to
start decommissioning of the Ulysse reactor have been
carried out. In 2015, ASN examined the updating of the
operating baseline requirements, whichwas a prerequisite
for decommissioning.
The arrival of a new industrial operator to run the Stella
facility represents a potential risk for the licensee who
must be vigilant with regard to the management and
monitoring of this activity. The operations to remove legacy
effluents fromBNI 35must also be continued in compliance
with the time frames of resolution 2014-DC-0441 of
15th July 2014.
The OSIRIS reactor was shut down at the end of 2015.
The prospect of this shutdown led to the updating of the
decommissioning plan and the defining of final shutdown
preparation operations which are to start in 2016 in
order to benefit from the skills and experience of the
operating team in place.
ASNnotes that the BNI 49decommissioning operations are
proceeding to the set schedules. The level of subcontracting
is particularly high on this BNI. Control of the operations
performed by the outside contractors is therefore an
important issue.
In BNI 50, ASNhas observed that the plannedmeasures
to improve the performance and traceability of technical
verifications and periodic tests have been implemented.
The removal from storage work in progress on BNI 72
is technically well controlled, but the effectiveness of
monitoring outside contractors still needs to be improved.
ASNunderlines that management of the replacement of
high-activity sources of BNI 77 in2015 led tononcompliant
storage in the centre’s installations lasting several weeks
and late notification of the fact. The CEAmust examine the
internal causes of this situation and the lack of transparency.
The Orphée reactor licenseemust bolster its organisation
for the planning and tracking of performance of
verifications and periodic tests. ASN’s inspections have
shown compliance with the planned actions and the
conditions for restarting after the two significant events
concerning the handling of fuel elements which occurred
at the end of 2014.
The CIS bio international plant in Saclay
ASN considers that the operating safety performance of
CIS bio international must be significantly improved.
ASNconsiders that the effortsmadebyCISbio international
to reinforce its integratedmanagement system, its human
resources and operatiing conditions that promote
cross-functionnality put in place in 2015, have not
yet produced lasting concrete results. The verification
of the conformity of operations, compliance with the
baseline requirements of the installation and those of
the regulations for the implementation of modifications
must be reinforced.
Further to noncompliance with the ASN prescriptions
issued after the periodic safety review, ASN applied
coercive administrative policing measures in 2014
and 2015. Formal compliance notices were sent first
of all, then, further to the failures to comply with these
notices, padlocking procedures were applied to oblige
CIS bio international to equip the installation with
automatic fire extinguishing systems in accordance
with predetermined deadlines. Pending finalising of the
works whose deadlines were not met, ASN prescribed
compensatory measures to step up control of the fire
risk through a resolution of 14th April 2015.
A large amount of work contributing to improving
safety, which has been in progress for several years, is not
completed. As a general rule, the large-scale undertakings
of CIS bio international are never completed within
reasonable time frames.
A new laboratory has been put into service and the
automatic fire extinguishing systems are partially installed
and functional. Complementary studies concerning
the consequences of accident situations remain to be
finalised.
The stated time frames for performing the actions defined
further to inspections and events are exceeded too
frequently. The deviations observed during inspections
and the predominance of organisational and human
factors in the causes of events reveal persistent weaknesses
in operating rigour, in intervention processes and in
assessing the importance of the deviations. Equipment
maintenance must be improved in particular.
ASNwill be attentive to CIS bio international’s compliance
with prescriptions, the meeting of its commitments and
its improvement of safety in operation. ASN expects an
increase in the effectiveness of the current organisation
and the industrial approach implemented. Consequently,
it will keep the facility under tightened surveillance
in 2016.
