What is a safety case nuclear?

How are safety cases used in agile development?

Agile development methods have been applied to safety case production. The review of safety cases is an important activity in the safety engineering process, performed throughout development, operation and maintenance, in which the safety case argument and evidence are scrutinized and challenged.

When does a safety case need to be revisited?

A safety case should be revisited when an existing product is to be re-purposed in a new way, if this extends beyond the scope of the original assessment. A safety case aims to show that specific safety claims are substantiated and, in the UK, that risks are kept ‘As Low As Reasonably Practicable’ ( ALARP ).

What are the elements of a safety case?

A safety case requires two elements: Supporting Evidence Results of observing, analysing, testing, simulating and estimating the properties of a system that provide the fundamental information from which safety can be inferred High Level Argument

Why do we need a safety case in the UK?

Such standards typically do not explicitly require an explicit argument for safety and instead rest on the assumption that following the prescribed process will generate the required evidence for safety. Many UK standards are non-prescriptive and call for an argument-based approach to justify safety, hence why a safety case is required.
