IAEA Publications on PSR, Configuration Management, and Design Basis Data Management
This subsection provides guidance documents on other important technical areas than ageing management: PSR, Configuration Management and Design Basis Data Management.
For further information, please contact SKALTO.
Guidance documents for PSR
The draft TECDOC entitled “Experience of member states in implementing periodic safety review” is being finalized.
Guidance documents for Configuration Management
Configuration management (CM) is the process of identifying and documenting the characteristics of a facility’s structures, systems and components and of ensuring that changes to these characteristics are properly developed, assessed, approved, issued, implemented, verified, recorded and incorporated into the facility documentation (IAEA TECDOC 1335).
“Configuration Management in Nuclear Power Plants (TECDOC 1335)” identifies the necessary attributes of a good operational CM. The concepts developed in this TECDOC present a basic approach to CM, taking into consideration experience gained from organizations and utilities which have successfully implemented partial or full CM programmes and from discussions at meetings organized on the subject.
The Safety Report, “Application of Configuration Management in Nuclear Power Plants” (Draft, to be issued) provides advice on how to meet challenges in the area of configuration management and examples of how different plants have implemented applications to strengthen the safety. The guidance in this report is primarily intended for nuclear power plant and utility management that have direct responsibility for implementing and supervising a strong and consistent configuration management. Safety authorities can also use this report for the review and verification of the safety approach applied by plant operators.
Guidance documents for Design Basis Data Management
The design basis for structures, systems, or components is the information that identifies the specific functions to be performed and the controlling design parameters and specific values or ranges of values for these parameters. The design basis stipulate the function of the SSCs, essential SSCs parameters of the stated functions and processes, the basic safety margins to be included in the design, accident and fault scenario expectations, environmental considerations and impacts, applicability of safety and industry codes and standards. The design basis of NPPs are used by the plant staff and the regulatory authority in judging the acceptability of the original design and of modifications to the NPP with respect to the safety of the NPP’s personnel, public and environment.
As a pilot project, the Agency has drafted a “Guideline for Design Basis Documents (DBD) Collation and Maintenance for WWER Reactors” and is providing assistance in this area through training and the exchange of experience. In the next step, this Guideline will be generalized to be applicable to all reactor types. To initiate efforts to consolidate the design basis documentation is in particular important for LTO of older plants. Older plants may require a number of modifications to meet current safety requirements applicable, for which the likelihood that the original designer/vendor may not be able to provide the needed support is highest, and, which for technical, organizational or other reasons do not have this information available.
The draft TECDOC entitled “Guideline for design basis documents (DBD) collation and maintenance for VVER reactor types” is being finalized.
