  1. TBM Safety Update Brad Merrill/Fusion Safety Program TBM WG Meeting UCLA, December 12th -14th, 2005

  2. Presentation Outline • Overview of TBM licensing process proposal made by J.-Ph. Girard (ITER SE&H Group Leader) at the last two TBWG meetings and what this could mean to TBM Safety and Regulatory Support • Updated Safety and Regulatory Support cost estimates based on recent guidelines from TomMann 2

  3. Possible TBM Licensing Scenarios Three TBM licensing scenarios presented by J.-Ph. Girard at the Garching TBWG meeting (July 2005) : • TBM is considered and analyzed in Initial Safety Files (scenario presently preferred by ITER) TBM is licensed at the same time as ITER, and operation of the TBM needs only ITER internal approval. This option requires detailed input from initial safety documents (Dossier of Options of Safety - DOS + Report Preliminary of Safety - RPrS) into for Requests for Permits (RPrC) so that TBM is covered by the appropriate Decrees (Decree Authorizing Creation –DAC). • TBM has no extensive description in the Initial Safety Files A description of the anticipated TBM system and enveloping estimates of radioactive wastes and operational/accidental releases is included in the initial safety documents. Licensing will require demonstration to the NSA that the TBM falls within the original envelope, but public review will not be required) • Non-scheduled TBM with respect to Initial Safety Files or supporting documents for issued Decrees Full licensing process required including public review 3

  4. Safety reports ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader 4

  5. – Safety Principles • General Safety Goals ·  Compliance of Safety Functions • Rules for event analysis and components classification – Operation conditions – Event analysis, Calculation codes – Nuclear/non-nuclear risks – Internal hazards analysis • Fire, explosion, chemical risk , load drop, flooding – External hazard analysis • Earthquake, aircraft crash ... – Justification of the design for SIC – Impact of the facility on workers, public and neighbouring environment (in any operation conditions + ALARA) – Normal + abnormal operation / effluents and releases – Quality Assurance (with regard to Safety) – Tests (related to Safety) for start-up + In Service Inspection – Waste (tritium inventory and materials could be a problem) and Decommissioning ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader Safety analysis as proposed by EU-PT&france in their 2005/2006 contribution (BJM – assumed to be for ITER based on GSSR input) 5

  6. D0: Safety report and public enquiry files approved by future operator and sent to authorities Key issue: time between approval by operator (or mandated representative) of safety files, requests for Public Enquiries and Building Permit TBM documentation Draft written together 30/06/2006 Documents available by 1/09/2006 Documents approved, signed and sent by 1/04/2007 First concrete 1/10/2008 ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader 6

  7. ITER Test Blanket Module in EU-FranceMeet the licensing dead line with consistent, sufficient inputs • Description of the experimentation and possible concepts, • Inventory at risk • Safety analysis: prove that all normal, incident, accident situations are under control, clear views on barriers, fire, explosion, scram, bottom-up analysis, TBM facility, facility  TBM • Do the TBMs introduces news accidental scenarios? • Do they substancialy increase risk? • Screening of standards incidental and accidental sequences • Codes & Standards (metallic (material), pressure vessel…) • Waste • Safety tests before start-up (generaly speaking, sequences for TBM experimentation) 7 ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader

  8. EFDA A proposal could be: To set the next meeting in Cadarache and to have the meeting followed by a workshop to finalise the licensing documentation (main objectives, safety and releases) with this calendar: ITER will ask EU-PT to send the canvas of needed information before 01/02/2006 A coordination officer will be mandate to work with partners on the documentation (02 to 06/2006) Workshop to finalize the job 06/2006 draft documents ready by 15/07/2006 under the coodination of the officer ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader 8 -

  9. Impact of TBM Licensing Scenarios on Cost and Schedule • Safety reporting requirements at this time are not very clear, but what is certain is that: • A safety analysis for the TBM that is comparable to ITER’s GSSR (basis for existing DOS and RPrS) has not been undertaken • A “bottoms up review” of to determine postulated initiating events (PIE’s) for the DCLL TBM has not be made • There is not enough time to complete these sort of analyses prior to submission of the RPrC or the issuance of the DAC • All TBM Parties have this same problem based on existing DDD submissions reviewed, but what is the status of the EU DDDs? • The only conclusion that can be drawn is that J.-Ph. Girard believes that the initial analyses can be repackaged with little effort to satisfy DOS and RPrS requirements for the DAC • Dave Petti will meet with J.-Ph. Girard in January to clarify safety reporting requirements and help set the foundation for proposed licensing workshop to be held in February 06 9

  10. ITER-IT/PT meeting CN Nov. 2005J.-Ph. Girard - ITER SE&HGroup Leader ITER Test Blanket Module in EU-FranceQA • Very stringentQA system mustbe implementedfor all safetycomponents • Requirementsfor this QA systemis close to theIAEA 50SGQ • Translation of the requirement given during meeting 10

  11. Impact of Quality Assurance on TBM on Cost and Schedule • All components of the TBM ancillary loops are safety grade components and will require a Quality Assurance (QA) program to obtain licensing/operating approval • A QA similar to ITER’s (based on IAEA 50-C/SG-Q, similar to ASME NQA-1 or 10CFR50 App B) should be adopted • Necessary parts of ITER QA are: • QA Director and a QA Plan • Document Control • Design to nuclear Standards (e.g., ASME B&PV Code Section IX on welds, Section V on NDE) • V&V of computer codes used in the design • Vendor certification and contracting • Audits and other oversight activities are required to ITER success, so plan for 10% cost increase for each WBS item 11
