Background
The second check and review on the P&T technology
(cid:122)
» made by the Japan Atomic Energy Commission (JAEC) in
2008-2009, and the final report has been issued in April, 2009
Future research and development plan on the P&T
(cid:122)
technology should be made
The Research Committee on P&T and MA Recycle,
(cid:122)
Atomic Energy Society of Japan (AESJ)
» noticed the usefulness of Technology Readiness Levels
(TRL) approach
» to support the planning of research and development on P&T
technology

Objectives
Technology Readiness Levels (TRL) approach
(cid:122)
» was used to provide a quantitative assessment for the
maturity of the P&T technology in Japan
The present TRL evaluation was
(cid:122)
» made by the Research Committee on P&T and MA Recycle,
AESJ
» independent of the Fast Reactor Cycle System Technology
Development Project (FaCT Project) in Japan
The main objective of the present TRL evaluation is
(cid:122)
» Not to provide absolute quantitative values of TRL
» But to discuss how to conduct the research and development
of the P&T technology

What is TRL?
TRL is a systematic metric/measurement system that
(cid:122)
supports assessments of the maturity of a particular
technology
» From a new concept that is viable based on first principles
assessment
» To full maturity of long-term routine operations of commercial
plant
» The intermediate steps are defined based on the logical
progression of the research and development towards
demonstration and deployment

Why use TRL?
TRL approach provides
(cid:122)
» a relative measure of where the technology maturity is
compared to the end objective of large-scale deployment
TRL is used as
(cid:122)
» a program management tool
– a common understanding of science and technology exit
criteria
– a consistent comparison of maturity between different
types of technology
– a communication tool between technologists and
managers
