Critical Section Selection Methodology for the U.S. EPR™ Standard Nuclear Power Plant
ASME 2010 Pressure Vessels and Piping Conference: Volume 8, 2010This paper presents a three-tier, critical section selection methodology that is used to identify critical sections for the U.S. EPR™ Standard Nuclear Power Plant (NPP). The critical section selection methodology includes three complementary approaches: qualitative, quantitative, and supplementary. These three approaches are applied to Seismic Category

The thermal-hydraulic design of the first PWR’s was mainly based on an experimental approach, with a large series of test on the main equipment (control rod guide tubes, RPV plenums ...), to check its performances. Development of CFD-codes and computers now allows for complex simulations of hydraulic phenomena.

The experimental problems linked to the use of the ultra-wide band high field-high frequency Electron Paramagnetic Resonance (HF2-EPR) spectrometers are illustrated with some key examples. The single pass technique is critically analyzed and compared with other techniques.

Exchange-coupled spin triads nitroxide-copper(II)-nitroxide are the key building blocks of molecular magnets Cu(hfac)(2)L(R). These compounds exhibit thermally induced structural rearrangements and spin transitions, where the exchange interaction between spins of copper(II) ion and nitroxide radicals changes typically by 1 order of magnitude.

EPR Kindred Methodologies for Multiversal FTL Communication
No faster-than-light (FTL) communication device exists today. This paper does not propose a hardware design, but instead examines—in a speculative, pre-device framework—how the FTL pipeline linking two hypothetical communicators would behave under the combined constraints of quantum mechanics (QM) and relativity.openaire +1 more source

The study of the complex of EPR characteristics of metabolic reactions involving free radicals and paramagnetic metal complexes revealed a pronounced dose-dependent dynamic SOS response of the most important life support systems of the body under General gamma irradiation. Studies in actively proliferating tissues of the ribonucleotide reductase enzyme
