The INPRO Methodology
The INPRO methodology identifies a set of Basic Principles, User Requirements and Criteria in a hierarchical manner as the basis for the assessment of an innovative nuclear system:
|Structure of the INPRO methodology using Basic Principles, User Requirements and Criteria|
It is intended that:
- The fulfilment of a Criterion for an INS is confirmed by the Indicator(s) complying with the Acceptance Limit(s).
- The fulfilment of a User Requirement(s) is confirmed by the fulfilment of the corresponding Criterion (Criteria) (bottom-up approach).
- The fulfilment of a Basic Principle is achieved by meeting the related User Requirement(s).
INPRO takes a holistic approach to assess innovative nuclear systems in seven areas:
As part of the updated INPRO methodology, this manual provides guidance on assessing the sustainability of a nuclear energy system in the area of economics. This is an independent assessment of the economic competitiveness of nuclear power, compared with available alternatives. It starts with a short description of the goals and output of energy system planning, followed by general background information on performing an INPRO economic assessment and presents a discussion of the basic principles, the associated user requirements and criteria. Additional background information on economic terms and support tools is provided in the appendices.
This manual is part of the updated INPRO methodology. It provides guidance on assessing the sustainability of a nuclear energy system in the area of infrastructure. INPRO Basic Principle in this area states that a country shall be able to adopt, maintain or enlarge a NES for the supply of energy without making an excessive investment in national infrastructure. The associated User Requirements and Criteria recognize the need to establish a national legal framework and corresponding institutions; adequate economic infrastructure to facilitate availability of credit lines; industrial infrastructure to cover mainly construction, transport and maintenance; socio-political infrastructure to allow long term commitment and public acceptance; appropriate human resources for all steps of the nuclear programme; minimization of the needed infrastructure for a given nuclear power programme; and regional and international arrangements which can be used for minimization of necessary national infrastructure.
The Basic Principles in the area of waste management have been derived from the IAEA Safety Fundamentals concerning "The Principles of Radioactive Waste Management". Thus, the generation of waste is to be kept to the minimum level practicable, securing an acceptable level of protection of human health and the environment without undue burdens on future generations, and all waste generation and waste management steps are to be taken into account.
The Basic Principles associated with proliferation resistance require that intrinsic features and extrinsic measures be implemented throughout the full life cycle of the INS, and that they be optimized, by design and engineering, to provide cost effective proliferation resistance. In an INS, the attractiveness of nuclear materials and technology for diversion to a nuclear weapons programme should be low, and the diversion of nuclear material difficult and detectable.
One Basic Principle has been defined by INPRO in the area of physical protection. It requires the implementation of an adequate physical protection regime throughout the lifetime of an INS. The corresponding User Requirements are based on the fundamental principles of the amended convention on the physical protection of nuclear materials and facilities, and emphasize the need to take into account jointly all aspects of physical protection, proliferation resistance and safety during all design stages of an INS.
Environmental impact from depletion of resources
This manual is part of the updated INPRO methodology. It provides guidance on assessing the sustainability of a nuclear energy system in the area of environmental impact from depletion of resources. A basic principle of INPRO in the area of environmental impact from depletion of resources is that a nuclear energy system will be capable of contributing to the energy needs in the 21st century while making efficient use of non-renewable resources needed for construction, operation and decommissioning. Recognizing that a national nuclear energy programme in a given country may be based both on indigenous resources and resources purchased from abroad, this publication provides background materials and summarizes the results of international global resource availability studies that could contribute to the corresponding national assessments.
In the area of safety of nuclear installations, the Basic Principles require that the INS enhance the concept of defence-in-depth, with an increased emphasis on inherent safety characteristics and passive safety features resulting in a health and environmental risk of an INS that is comparable with that of industrial facilities used for similar purposes.
