No U3/U4 in actual design • Design for 30 years life with possibility for refurbishment • CTRF will have long term storage capacity for tritium CTRF Basic Diagram STACK HVAC ADS TRS LPCE CDS TGHSS Zona LPCE Zona CDS Zona TGHSS LIQUID COLLECTION SYSTEM Zona TRS 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 Building TRS CD System ADS L4 L3 L2 L1 L0 B1 LPCE System HVAC Shaft Heating System Tritiated water holding tank system Tritium Storage 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 Torus Fuelling Systems Neutral Beam Heating Storage and Delivery System Tritium / Deuterium from External Sources Neutral Beam Injector Cryo Pumps Isotope Separation System Water Detritiation Tritium Breeding Test Blanket Tokamak Exhaust Processing He Glow Discharge Cleaning Analytical System Torus Cryo Pumps Roughing Pumps On-line Sampling from T-Plant Systems Protium Release Atmosphere and Vent Detritiation Systems Off-gas Release 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
