Risk Assessment Activities § General RA objective: answer to the questions What can go wrong? How probable is it ? What are the consequences? § Qualitative Analysis § Quantitative Analysis Dependability Analysis (Fast Analysis) § C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09

Risk Assessment: Dependability Analysis § § Unrepairable OM and DU, Maintenance 1 week per year. Different configurations Unrepairable OM and DU, Maintenance 1 month per year. Different configurations C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09

Risk Assessment: Achievements q Qualification of the methodology and models through many calculations performed on the concept designs q Application of the methodology and models also to the construction and operation life of KM 3 Ne. T Needs to obtain the failure rates of the components: q Government or commercial data q From database Test Maintenance is an issue that affects the availability of the detector and the MTTF of the components and systems of KM 3 Ne. T detector C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09

Quality Assurance Activities § Development of the Quality Assurance System according to ISO-9000 family - Quality Assurance Manual: plan and organization Manual of the activities of KM 3 Ne. T in all its phases to insure that the level of quality defined is achieved - Definition of the Quality plans and general procedures for KM 3 Ne. T to be developed and update, once the project and its phases reach a well defined or modified status - Definition of the Quality management system - Definition of the Quality management document - Definition of a Database for the qualification, construction and operation of KM 3 Ne.

Quality Assurance: Database § For Traceability of the components and systems of KM 3 Net qualification, construction and operation life of KM 3 Ne. T § For document management During the Design study a prototype function was developed: Test report record § C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09

Quality Assurance: Achievements q Development of QA according to ISO 9001 Ø To be considering the starting point to implement the KM 3 Ne. T Quality Standard through the experience gained by the qualification and optimization processes Ø To be diffuse in KM 3 Ne. T collaboration through training on ISO 9000 and KM 3 Ne. T QA System. q Development of the database prototype Ø its future implementation is already planned q Needs to define a qualification process of components systems and to design testes C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09

Conclusions q RA procedures and models have been developed and qualified Ø for the qualification, optimization, construction and operation of KM 3 Ne. T q QA System has been developed Ø it is needed to be updated and implemented to become the KM 3 Ne. T QA Standard Ø It is needed to diffuse it by specific training q A prototype database was realized C. Sollima, INFN-Pisa VLVn. T 09, Athens, 15 October '09
