What is the expertise needed to perform an evaluation?

Familiarity with the PR&PP methodology, the system design, and the general requirements of non-proliferation (e.g. international safeguards) and physical protection. Note that this combined expertise need not reside in a single evaluator, but can be represented by an assessment team.

What is the relation between PR&PP and IAEA safeguards?

PR&PP incorporates International Atomic Energy Agency (IAEA) safeguards as external components (sometimes referred to as extrinsic measures) of the nuclear energy system being assessed. PR&PP can be used by designers at an early stage to assess where and how one might implement safeguards, in order to guide conceptual design decisions. Safeguards is one feature of a good design that enables th... more

Why was the PR&PP methodology developed?

The PR&PP methodology was developed to address one of the four goals identified for future nuclear energy systems in the 2002 Generation IV Roadmap (i.e., next-generation power reactor designs that will see commercial deployment beyond 2030): Generation IV nuclear energy systems will increase the assurance that they are a very unattractive (i.e., present significant barriers) and the least desi... more

Does PR&PP apply to national or sub-national actors?

Generally PR applies to national actors, and PP to sub-national actors, although there can be interaction between these two.

How does a PR&PP evaluation relate to a safety and reliability evaluation?

There are possible synergies between PP&PP and safety/reliability if assessed early enough in the design process and possible conflicts that may be addressed at this time. Even at the earliest stages of conceptual design it is recommended that, in addition to representative safety challenges, designers perform qualitative assessments of the potential system response to representative PR and PP c... more

At what stage of an evaluation should a PR&PP evaluation be performed?

PRPP can be performed at the earliest stages of design, and then revisited periodically and detail added as a design progresses and more detail is known.

To what type of systems does a PR&PP evaluation apply?

PR&PP is designed for the assessment of nuclear energy systems, with no specific technology dependence.The elements of the fuel cycle (i.e., components of the fuel supply, reactor, or spent-fuel management architecture) that are included in the assessment are dependent upon the users needs.

Are there other methodologies for performing similar evaluations?

There are other assessment methodologies (e.g. INPRO). The methods are complementary. INPRO assessments can assure that best practices have been considered, and adopted where appropriate, in system design. PR&PP assessments can assure that the system response to PRPP challenges will be acceptable.

Will the PR&PP methodology be updated or is it in final form?

The methodology is ready for use, currently as Revision 6. It will receive updates as feedback is received on implementation, and as the field of knowledge in non-proliferation and physical protection evolves.

What are benefits to performing PR&PP analysis early in the design process?

Benefits include synergies with safety and economics, reduction of risk for schedule slippage, efficiencies in implementing PR&PP-related system design components, guidance on design decisions with maximum flexibility to early design stage.

Where can I find more information?

The PR&PP Evaluation Methodology report is available online. The journal Nuclear Technology provides several articles discussing the methodology and providing examples of its application, in Vol. 179, pgs. 1-96, July, 2012.

How does a PR&PP evaluation differ from an IAEA INPRO evaluation of proliferation resistance?

PR&PP is a design tool that evaluates the system response to a spectrum of potential PR&PP challenges (e.g., diversion, clandestine program, break-out scenario and terrorism), and can also be used by customers or policy makers in guiding decisions; INPRO is a best-practices checklist aimed mainly at assisting embarking countries in making decisions. INPRO is a broad assessment, including high-le... more
