Basic technology development of advanced non-destructive detection / measurement of nuclear material for nuclear security and nuclear nonproliferation

The Integrated Support Center for Nuclear Non-proliferation and Nuclear Security (ISCN) of Japan Atomic Energy Agency (JAEA) has been conducting (based on collaborations with JAEA other centers) the following basic technology development programs of advanced non-destructive detection/measurement of nuclear material for nuclear security and nuclear non-proliferation. (1) The demonstration test of the Pu-NDA system for spent fuel assembly using PNAR and SINRD (JAEA/USDOE(LANL) collaboration, completed in JFY2013). (2) Basic development of NDA technologies using laser Compton scattered gamma-rays (Demonstration of an intense mono-energetic gamma-ray source). (3) Development of alternative to He-3 neutron detection technology. (4) Development of neutron resonance densitometry (JAEA/JRC collaboration). This paper introduces above programs. (author)
