TCWS Design and Centralized procurement for ITER Piping Information Day
� Each Supplier or Subcontractor providing equipment or servicesto the ITER Organization must provide a dedicated Quality Plan.
� A Quality Plan covers the whole scope of the contract anddescribes the operational quality system (based on ISO 9001 orequivalent) to ensure that:� Contract requirements will be met� Evidence of such compliance is maintained
� Work shall not start until the relevant Quality Plan has beenaccepted by ITER.
4 - Quality Assurance requirements
Page 7

� The Quality Plan is contract specific and shall identify:
• the specific allocation of resources, duties, responsibilities andauthority;
• details of all suppliers/subcontractors and how interfaces will bemanaged;
• the specific procedures, methods and work instructions to beapplied;
• the specific methods of communication, both formal and informal,to be established between working groups.
� Much of the generic documentation needed to prepare the Quality Planwill normally already exist as part of the Supplier/Subcontractor’squality management system and supporting procedures. The QualityPlan need only refers to this documentation and shows how it is to beapplied to the particular contract.

Manufacturing and Inspection Plan (reference ITER_D_22MDZD)
� Each Supplier and sub-contractor shall supply the DA with a MIPlisting the sequence of manufacturing operations encompassing thewhole scope of the contract (review of drawings, verification ofmaterials, manufacture, inspection and test to delivery…).
� MIP allows supplier, DA and IO to mention control points (NP, HP,WP…).

Deviations and Non Conformances (reference ITER_D_22F53X)
� Deviation: A planned alternative to a specified requirement.
When a deviation to IO specifications is anticipated theSupplier/Contractor shall discuss it with the IO/DA responsible officer asappropriate for that ITER work activity. If the proposal is consideredbeneficial, the Deviation Request shall be sent to IO for approval.
� Non-Conformance: Any condition, which does not comply with a
specified requirement.
When a non-conformance is identified the Supplier/Contractor shall:• Identify, and segregate when practical, the non-conforming item• stop any further work on the item until a decision is made• record and report the occurrence by raising a Non-conformance
Report• Minor Non-conformances are sent to IO for information• Major Non-conformances are sent to IO for approval

• IO recognizes the basic principles of competition, fair andequal treatment of Tenderers
• These principles shall ensure that the IO can obtain the bestvalue for money by soliciting participation of a number ofqualified firms.
� Procurement and Contracts Division (PCD) :
• PCD primary objective and responsibility is to protect the IO’sinterest while procuring supplies, services, and works to meetits organizational requirements.
• PCD in charge of the management of tendering processesand then administrating the contracts

� Ensure that offers are sought only from suppliers who have thefinancial capabilities as well as requested skills, equipmentand experience to perform works or services as described inthe technical summary (and later in the technicalspecifications).
� The PQ form includes :• Questionnaire with Pre-Qualification criteria (pass/ fail)• Technical Summary of the scope • Administrative forms

� Contractual document signed between the IO and Supplier(s)which sets the terms and conditions under which anyDomestic Agency or their contractors may procure identifiedsupplies
� Concluded and signed by the IO to ensure standardization ofsupplies for the ITER Project

� Contemplated selection process in most of the cases:
� Call for Tender with Call For Nomination and Pre-Qualification
� Award criteria based on Lowest Price Technically Compliant approach where the Technical Compliancy for each Requirement is to be justified in the Tender.
