QUALITY ASSURANCE ACHIEVEMENTS
Development of QA according to ISO 9001
To be considered as the starting point to implement the KM3NeT Quality Standard,KM3NeT Quality Standard, through the experience gained in the qualification and optimization processes
To be distributed within KM3NeT collaboration through training on ISO 9000 and the KM3NeT QA System.
Development of the database prototype
its future implementation is already planned
Need to define a qualification process for components and systems, then to design tests
QUALITY ASSURANCE SYSTEM
Following the study of possible quality standards, the ISO 9000 family is applied, both for its wide application in industry and its freedom to implement the QMS to the needs of KM3NeT project.
The QAS is implemented to follow two requirements both of QA and RA:
- the quality control process through the Deming cycle
- the needs of the RA to proceed in parallel and interact with the design.
According to ISO 9001, KM3NeT is developed in processes. The detector is represented by a tree logic scheme from the upper layer to the lower.
Once a function of the availabilities of the components is determined two general questions can be answered:
Given the availabilitiesGiven the availabilities of the components of the system, determine the availability of the system.
Given a performance criterionGiven a performance criterion as a required system availability level, determine the component availabilities that satisfy this criterion.
The required functionrequired function of the telescope is to have an appropriate number of optical modules available to detect neutrino interactions. An additional requirement is that the telescope is available for A% of its useful life, assumed here to be equal to 10 years.
As a first approximation, the steady state dependability of the system was calculated. Assumptions made at this stage included that: a) parts of the neutrino-detector will be designed in such a way that they will be retrievable , serviceable and replaceable; b) failure of a component is assumed immediately detectable; and c) repair can either start immediately, or may be only possible after predetermined time delays.
The implementation of the QA and RA procedures follows the Deming cycle (“PDCA”: Plan, Do, Check, Act).
It is a quality control process that allows the optimization of the design and of the project.
Goals• Define a suitable methodology for RA & QMS• Perform a Risk Analysis of design and operation of the telescope,
by a suitable methodology for the RA investigation• Define and diffuseDefine and diffuse the “Quality Culture”• Obtain a common standardisation by an integrated strategy (QMS
& RA, Health-Safety-Environment).

FRAMEWORK and STRATEGIES for QUALITY ASSURANCE and RISK ASSESSMENTFRAMEWORK and STRATEGIES for QUALITY ASSURANCE and RISK ASSESSMENT in the KM3NeT NEUTRINO TELESCOPE PROJECTin the KM3NeT NEUTRINO TELESCOPE PROJECT
The KM3NeT detector, currently being designed , is expected to be operated in the Mediterranean Sea at a depth of up to 5.000 meters (implying an ambient pressure of up to 500 bar) in the chemically-aggressive deep sea environment for at least 10 years without significant degradation. This requirement also applies to each sub-system, component or part of the detector, imposing strict standards to each step of the detector production, transportation and deployment on the sea bed.Through actions planned along well-defined procedures, quality assurance (QA) allows for achieving the defined requirements with a calculable level of confidence  .Through qualitative and qualitative analysis, RA allows for the identification of critical points in the design and/or operation of the detector and for devising improvements and corrective and mitigation actions .Within the framework of KM3NeT, QA and RA are coupled to form an integrated system, that allows for simultaneous monitoring both of the critical points and of the quality control (QC) actions developed to assure the fulfilment of the defined requirements.
