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 ...

QCD on the highly parallel computer AP1000

Nuclear Physics B - Proceedings Supplements, 1992
Abstract We have been running quenched QCD simulations on 32 4 and 32 3 × 48 lattices using a 512 processor AP1000, which is a highly parallel computer with up to 1024 processing elements. We have developed programs for update, blocking and hadron propagator calculations.

The parallelization of the incomplete LU factorization on AP1000

1998
Using a finite difference method to discretize a two dimensional elliptic boundary value problem, we obtain systems of linear equations Ax=b, where the coefficient matrix A is a large, sparse, and nonsingular. These systems are often solved by preconditioned iterative methods.

Improvement of the Reactor Control System in AP1000

Volume 1: Operations and Maintenance, Engineering, Modifications, Life Extension, Life Cycle and Balance of Plant; I&C, Digital Controls, and Influence of Human Factors, 2017
AP1000 is a two-loop pressurized water reactor (PWR) developed by Westinghouse, which uses the forces of nature and simplicity of design to enhance plant safety and reduce construction costs. Compared to traditional reactor control strategies, the AP1000 adopts an advanced Mechanical Shim (MSHIM) core control strategy, which controls the reactivity and

QCD ON THE MASSIVELY PARALLEL COMPUTER AP1000

International Journal of Modern Physics C, 1993
We present the QCD-TARO program of calculations which uses the parallel computer AP1000 of Fujitsu. We discuss the results on scaling, correlation times and hadronic spectrum, some aspects of the implementation and the future prospects.

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

Westinghouse AP1000 advanced passive plant

Nuclear Engineering and Design, 2006
Abstract The Westinghouse AP1000 Program is aimed at making available a nuclear power plant that is economical in the US deregulated electrical power industry in the near-term. The AP1000 is a two-loop 1000 MWe pressurizer water reactor (PWR). It is an uprated version of the AP600. Passive safety systems are used to provide significant and measurable

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.
