A framework of the requirements for the management of a nuclear fuel cycle facility

This study introduces a system that can confirm whether all requirements are satisfied, by systematically managing from the highest design requirements to the requirements for the lowest unit devices of the PRIDE facility through mutual relationships, and effectively traces the influences of the requirement changes. To carry out the technology traceability based on pyroprocess facility design data and research data, we need a database system that can manage an extensive amount of data. This paper explains the procedure of developing a pyroprocess system engineering framework and data schema established for this. To confirm whether the technology traceability is carried out within a reliable boundary based on the top requirements, system requirements, sub system requirements, and component requirements of the derived PRIDE system, an experiment was done with an Ar (Argon) cooling system as a target. As a result of verifying the validity of the technology traceability with the sample data input, it was confirmed that, when pyroprocess separation is designed in an Inert (Ar) gas atmosphere, from the top requirements of the pyroprocess, to the capacity and electricity of the Chiller unit, which is the unit process device composed of an Ar cooling system, and down to the requirements for the type, can be effectively traced.

► The study of pyroprocess system engineering framework and data schema carried out.
► It introduces analysis and decision method to logically analyze the traceability.
► The interface between major sub system composing the PRIDE was defined.
► The validity of traceability was confirmed through the Ar cooling system.
