"The Machine Protection Risk Management Lifecycle at the European Spallation Source ERIC will be presented.
Reliability and availability requirements are taken into consideration before and during the design of the Machine Protection Systems at ESS. This is done by systematically identifying, assessing and mitigating damage risks to equipment.
The machine protection risk management lifecycle has the following phases:
1. Identification of concept and scope
2. Risk identification
3. Risk assessment
4. Risk mitigation
5. Requirement specification
6. Design and implementation
7. Verification and validation
In the first phase it is determined which systems will have a detailed Machine Protection analysis and which systems are excluded.
The outcome from the risk identification, risk assessment and risk mitigations is documented in a machine protection analysis. The analysis is performed in workshops, with the related system owners, technical experts and system engineers. The methods used for the identification, assessment and mitigations will be described in more detail.
Based on the analysis the Machine Protection requirement specifications is developed, which identify the systems required to fulfil Machine Protection related functions.
The requirements are fulfilled through the design and implementation process and are then confirmed through verification and validation."
