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.

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

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

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 ...

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.

Analysis of safety margin of in-vessel retention for AP1000

Nuclear Engineering and Design, 2010
In-vessel retention (IVR) of core melt is a key severe accident management strategy adopted by most operating nuclear power plants and advanced light water reactors (ALWRs), AP600, AP1000, etc. External reactor vessel cooling (ERVC) is a novel severe accident management for IVR analysis.

Experimental investigation of upper plenum entrainment in AP1000

Progress in Nuclear Energy, 2015
Abstract Upper plenum liquid entrainment can reduce the coolant inventory in the reactor pressure vessel and poses great threats to core uncovering and melting in the accident conditions. To make up for the deficiency of upper plenum entrainment database, the Automatic Depressurization and Entrainment TEst Loop (ADETEL) was constructed and upper ...

Toward lattice QCD simulation on AP1000

Nuclear Physics B - Proceedings Supplements, 1992
Abstract AP1000 is Fujitsu Laboratory's experimental parallel computer consisting of up to 1024 microcomputers called cells. It is found that each AP1000 cell can sustain two to three megaflops computational speed for full QCD lattice numerical simulations in IEEE 64-bit floating point ...
