Nuclear Power Plants (NPP) is one of alternative energy that can be used to replace fossil energy. NPP a clean doesn't emit CO2 as residue from the power plant. Pressurized Water Reactor (PWR) most widely commercial reactor date. This usually uses UO2 fuel with enrich U-235 and produce plutonium waste nuclear. In this study, natural uranium addition spent PWR, calling it Uranium-Plutonium Nitri...

In this paper we present the developments in heat flux measurements using gradient sensors (GHFS). The GHFS is a sensor made of artificially created material with anisotropic thermo-electrical properties. Its properties including small size, robustness and low response time make it valuable addition for characterizing space-limited geometries as well harsh environmental conditions. This makes i...

The initial design life of nuclear power plant is 40 years. In 60 year extending license application, the fatigue component should be evaluated under influence factors pressurized water reactor coolant environment. Because original used a more conservative analysis method, result could not meet requirement Cumulative usage factor RCC-M. An optimizing method studied, and as an example Safety Inj...
