PD IEC/TR 63084 is a document that discusses instrument and control (I&C) components important to the safety of nuclear powers plants. The main objective of PD IEC/TR 63084 is to maintain integrity of safety systems containing devices and equipment used in NPPs.
PD IEC/TR 63084 is a technical report that provides an assessment framework and activities for efficient and transparent qualification of I&C platforms for use in nuclear applications important to safety, according to nuclear standards and state of the art. The assessment aims at a prequalification of I&C platforms outside the framework of a specific plant design.
Qualification is assumed to be a prerequisite for allowing the particular I&C platform to be used for the implementation of the safety classified I&C system. It is to enable parties implementing particular plant-specific I&C systems to concentrate on application functions, while for basic system functions to rely on platform qualification.
The features of the I&C platform to be qualified will be identified in requirements on the I&C platform. The requirements can vary, but in essence, are based on suppliers' claims on the product scope and functionality. Those claims are normally given in platform documentation such as system descriptions and supplier's requirements for design, implementation, verification & validation. They are all based on the appropriate IEC SC 45A standards and national regulations.
PD IEC/TR 63084 on nuclear power plants are useful to:
A nuclear power plant (NPP) has a large number of components and equipment, which are all coordinated by instrumentation systems. Hence, the safety of nuclear power plant instrumentation is important for support and reliable power generation through controlling plant processes.
PD IEC/TR 63084 provides an evaluation foundation and requirements for the efficient and transparent qualification of instrumentation and control platforms for use in critical nuclear applications, in accordance with nuclear standards.
PD IEC/TR 63084 guidance on evaluation of the hardware and software functions provided by the platform ensure safe and cost-effective life-cycle support of instrumentation and control systems. That would include tools for software engineering and software development (software module libraries), code generation, validation, maintenance, etc.
