Codes and methods improvements for safety assessment and LTO: varied approaches
نویسندگان
چکیده
Nuclear safety has always been at the heart of concerns nuclear power plant operators and developers, as well various research organizations regulatory authorities. Over last decades, all these actors have developed integrated a large number calculation codes other tools into their work. From system approach to local understanding phenomenon on given component, from neutronics operation optimization for long-term operation, methods constantly evolving since appearance, in order be able integrate new designs components, improve results modeling physical phenomena or quantify thus reduce uncertainties results. Currently, several H2020 Euratom projects are working improvement methods. This article will focus three projects: CAMIVVER (Codes And Methods Improvements VVER comprehensive assessment), APAL (Advanced PTS Analysis LTO), sCO2-4-NPP (innovative SCO2-based heat removal technology an increased level Power Plants) illustrate our thinking frameworks. First, we present work adopted with regard different used each projects. We then conclude overall analysis approaches, highlighting difficulties successes projects, identifying areas general codes.

15 صفحه اولUltrasonic and Cooling Approaches for Reinforcement of the Microextraction Methods
Since solid-phase and liquid-phase microextraction (SPME and LPME) were introduced, as effective solvent-free methods, many efforts have been made to improve their modes and applications. However, due to limitations with sensitivity and efficiency, researchers have focused on improving the performance of their basic primary modes. In this way, in recent years, different methods such as ultrason...

although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولSafety Assessment of cryIAc for human, animals and environment
Risk assessment of a transgene is one of the key steps in genetic transformation. Hence, in order to use cryIAc gene for production of transgenic plants, a library and in-silico research was performed to confirm safety of the gene for human comsumption, animal feed and environment. In the first step, the molecular mechanism of action of the CryIAc protein and its specific receptors in the midgu...
متن کاملImprovements of two preconditioned AOR iterative methods for Z-matrices
In this paper, we propose two preconditioned AOR iterative methods to solve systems of linear equations whose coefficient matrices are Z-matrix. These methods can be considered as improvements of two previously presented ones in the literature. Finally some numerical experiments are given to show the effectiveness of the proposed preconditioners.
