Le réacteur AP1000

Annales des Mines - Réalités industrielles, 2012
L’année écoulée a été difficile pour l’industrie nucléaire, notamment pour les entreprises cherchant à construire de nouvelles centrales. Il est inutile de rappeler les événements survenus à Fukushima, au Japon, en mars 2011. Ceux-ci auront un impact sur l’ensemble des projets nucléaires à travers le monde pour les années à venir, cela sous différentes

AP1000® Plant Adaptation To European Markets

Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle and Balance of Plant; Nuclear Fuel and Materials; Plant Systems, Structures and Components; Codes, Standards, Licensing and Regulatory Issues, 2014
The AP1000® plant is an 1100-MWe pressurized water reactor (PWR) with passive safety features and extensive plant simplifications that enhance construction, operation, maintenance and safety. One of the key design approaches in the AP1000 plant is to use passive features to mitigate design basis accidents. Active defense-in-depth (DiD) features provide

AP1000® SBLOCA simulations with TRACE code

Annals of Nuclear Energy, 2015
Abstract The AP1000 ® is an advanced pressurized water reactor (PWR) design developed by Westinghouse which implements passive safety systems to provide core cooling in case of accident. The performing of such systems must be evaluated through the performance of experiments and simulations with a variety of thermal–hydraulic codes.

Off-Site Emergency Response of AP1000

Volume 3: Nuclear Safety and Security; Codes, Standards, Licensing and Regulatory Issues; Computational Fluid Dynamics and Coupled Codes, 2013
Considering the emergency evacuation of Fukushima, special attention shall be paid on the reasonableness of the emergency evacuation area and the population distribution in the site vicinity. Based on the radioactive release source of AP1000 in the event of a severe accident, this paper proposes the classification of emergency area of AP1000 and ...

Low-Latency Message Communication Support for the AP1000

[1992] Proceedings the 19th Annual International Symposium on Computer Architecture, 1992
Low-latency communication is the key to achieving a high-performance parallel computer. In using state-of-the-art processors, we must take cache memory into account. This paper presents an architecture for low-latency message comunication and implementation, and performance evaluation.

Improving AP1000 parallel computer performance with message communication

Proceedings of the 20th annual international symposium on Computer architecture - ISCA '93, 1993
The performance of message-passing applications depends on cpu speed, communication throughput and latency, and message handling overhead. In this paper we investigate the effect of varying these parameters and applying techniques to reduce message handling overhead on the execution efficiency of ten different applications.

Architecture of highly parallel ap1000 computer

Systems and Computers in Japan, 1993
AbstractThis paper describes the architectural features of the AP1000 message‐passing computer. The architecture is designed to speed up barrier synchronization, data distribution and collection, broadcasting, and message handling. In recent message‐passing computers, the most significant communication overhead is that associated with interrupt ...

AP1000 Plant Typical Operational Transient Analysis

Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle and Balance of Plant; Nuclear Fuel and Materials; Radiation Protection and Nuclear Technology Applications, 2013
According to advanced light water reactor (ALWR) Utility Requirement Document (URD), plant control systems should be designed to meet the specified design requirements for an advanced 1000 MWe class PWR nuclear power plant (NPP). As per the plant design requirements, AP1000 control systems were simulated, and plant thermal-hydraulic ...

The AP1000 reactor?the nuclear renaissance option

Nuclear Energy, 2004
The AP1000 is a two-loop, 1150 MWe pressurised water reactor (PWR) with passive safety features and extensive plant simplifications to enhance construction, operation and maintenance. The AP1000 design is derived directly from the AP600, a two-loop, 600 MWe PWR. The AP600 uses proven technology, which builds on over 30 years of operating PWR experience
