Analytical techniques Nuclear Forensics Nuclear Security Security Summit
Japan Atomic Energy Agency (JAEA) initiated R&D for nuclear forensics in 2011, responding to the Japanese national statement at Nuclear Security Summit in 2010. We have developed the basic analytical techniques required for nuclear forensics (isotopic composition analysis, impurity analysis, particle analysis, age-dating, prototype nuclear forensics library) and made efforts to sophistication of these technology as well. Through participating the 4th ITWG Collaborative material exercises, we could test...

degree bend High-cycle thermal fatigue Secondary flow T-junction
In nuclear power plants, there are many T-junctions at which different temperature fluids are mixed. When the fluids with different temperature are mixed, temperature fluctu ation in fluids reachs wall and high-cycle heat fatigue occurs. Depending on amplitude and frequency of temperature fluctuation, it could lead to pipe rupture accident at wo rst. In addition, in case of the T-junction with 90-degreee bend at upstream, there is higher risk for pipe rupture accident due to secondary flow which arises in ...
