Production of an "Octopus diagram" defining the principal functions and constraints in the environment
Requirement:
The objective of this study was to define the Specification for modifications to be applied to an industrial emergency power unit so that it could fulfil specific requirements, notably in terms of the safety of the target application. This generator, classed as "important safety equipment", fulfils an emergency power supply function for a test nuclear reactor.
The study therefore involved defining the additional tests or studies which will make it possible to qualify the diesel generator unit with respect to these requirements.

Realization:
Capsim began by compiling a functional specification (external functional analysis) defining the various conditions of use and the relations which maintain the generator and its environment.
Each of these functions is then associated with criteria for the values that make it possible to quantify their condition and correct realization. The criteria for more than 80 values (with source references allowing tracing and justification of the values selected) were then defined.
An internal functional analysis of the target power unit (broken down according to functions) was performed.
The variations from the industrial solution based on the specific requirements were then identified by comparing the criteria from the functional specification and the internal analysis. These variations were analyzed with the manufacturer of the power generating unit.
Finally, Capsim drew up a proposal for modifications to be carried out on the envisaged solution as well as additional tests and studies required for its qualification.

Results:
The results were reported in the form of an action plan of modifications and studies to be carried out and in the form of test protocols required to bring the system into compliance.
