ICSI TRF Status
• Licensed for construction for 30g tritium
• Licensed for commissioning for low tritium level –
initial start
• Tritium on site – 200 kg from CNE Cernavoda
• Work procedures and equipment upgrading for
facility
• Tritium laboratory notification
• Environmental laboratory notification
CERNAVODA TRF
CTRF
• It was proposed in 2004 to start the program for a TRF
• Basically as is it: a five phase project:
– Phase I – Feasibility study – approved in 2007
– Phase II – Design of CTRF – starts in 2008
– Phase III – Procurement & Construction – since 2010
for long term delivery equipments
– Phase IV – Commissioning/Training/Operating
– Phase V – Decommissioning (with U2
decommissioning)
• Technology used – LPCE & CD – similar in Wolsung,
Korea and ICIT, Romania
• Time to finish (estimated): 2013
CTRF Technical Specification
• CTRF will start at 54 Ci/kg
• Target: to reduce the tritium content to 10 Ci/kg in 2
years
• Detritiation factor 100
• Upgrading possibility for heavy water - from minimum
99.7% to 99.95%
• To be used by U1 and possibility to serve also U2. No
U3/U4 in actual design
• Design for 30 years life with possibility for refurbishment
• CTRF will have long term storage capacity for tritium

Location of CTRF
Differences to ICSI TRF
• Design of more than 95 CTRF systems
(<25 in ICSI TRF)
• Issue of more than 45 basic design and
licensing documents
• CTRF is connected to U1, but 8 new
systems had to be implemented
• 5 CTRF licenses to be obtain from local
& central authorities and regulatory body
CNCAN
Licensing
• Initial, at beginning of contract, 3
licenses from CNCAN had to be
obtained: location, safety and
construction
• After discussions, a different approach
was approved using the ICSI TRF
experience – only 2 licenses from CNCAN
• Other licenses – initial approach
Licensing documents issued up-today
• Initial design manual of CTRF – based on tritium
experience
• List of code and standards applicable – based on ASME
codes, Canadian standards, Romanian standards
• Safety Design Guides for CTRF – in revision
• CTRF system classification list - in revision
• Seismic qualification of CTRF systems - in revision
• List of safety systems and safety related systems - in
revision
• Risk hazard for CTRF – in revision
• CU license (from local authorities) – approved in October
2008 after 3 month
• Environment initial documents
• PSAR content agreed with CNCAN
CTRF design phase status
• 75 % of all systems already designed (different
revision)
• Main systems:
–

–
LPCE system – revision 2
CD system – revision 2
Interface systems (HWFS & HWPS) – revision 1/2
HVAC, ADS, TGHSS, VTMS – revision 0 issued
• 3 systems at the beginning (TRS, DMS, AcDS)
• Some of support systems in final stage

Milestones for CTRF design
• Technical project – November 2009
• Final review of TP and issuing final form –
December 2009
• PSAR – First edition December 2009, final
February 2010
• License for construction/construct of CTRF
– April/May 2010
• Detailed design of CTRF – June 2010
WDS ITER
ITER - WDS
ITER – an important subject to Romania and ICSI
• From Romania point of view, materials, water detritiation equipment
and systems can be provided to ITER.
• Romanian experience can be used for Water Detritiation System, with
tritium storage, recombining processes for
hydrogen/deuterium/tritium, materials studies or design using
professional software CATIA.
• Take in account large quantities of tritium from Cernavoda site,
Romania can be the major player on European tritium market, having
in view that Romania is a European Union member.
• Romanian companies can provide services and equipment to ITER
• ICSI is on the list of potential supplier for ITER and open to tender
ICSI for ITER up today

ICSI for ITER
• ICSI starts in 2000 the work for WDS
• ICSI develop catalyst for LPCE columns in WDS,
including endurance tests
• Development of components for WDS in CATIA
V5
• Training networks for young specialists
– “Preparing the ITER Fuel Cycle”
– “Tritium Technologies for the Fusion Fuel Cycle TRI-
TOFFY”
ICSI for ITER in next future
• Most of the items are related to WDS
• ICSI will participate in consortium for:
– Development of method for highly tritiated
water handling in ITER Tritium Plant. Phase 1
– Support for development of Water Detritiation
Systems
• ICSI will send specialists in EU research
centers to support fusion technologies
research
Conclusions
• Romania developed technologies for tritium and will have a
full experimental TRF in next future (by ICSI)
• ICSI has the technology for tritium removal facilities and
therefore ICSI expertise can be used for ITER/CANDU units
• First industrial TRF in Europe will be on Cernavoda site
• From Romania point of view, the main source of tritium for
ITER is CNE Cernavoda
• There is a different approach between ITER and CTRF (ex.
site, code and standards, systems), but CTRF expertise can
be used for ITER. CTRF will starts before WDS from ITER
• For tritium (both ITER and CTRF) a common effort and
collaboration is necessary, more than today
