| 摘 要： | 随着计算机的快速发展和超算的应用，开展反应堆多物理、多尺度、多过程耦合成为可能.数值反应堆通过构建一个虚拟堆，在其上开展多物理过程研究，把过去孤立的过程耦合起来，去掉各种简化和近似，向高保真、精密计算逼近.研究手段由实验驱动、工程导向，向科学数值模拟转变.通过调研美国的CASL（The Consortium for Advanced Simulation of Light Water Reactors）计划和欧洲的NURESAFE（Nuclear Reactor Safety Simulation Platform）计划，结合近年核能开发中面临的挑战问题，包括软件自主化中的一些关键技术，提出在国内开展数值反应堆工程的建议设想，供业内专家学者共同探讨.

| Abstract: | With rapid development of computer and super computation, coupling for multi-physics,multi-scale and multi-process has become possible. Some lone process are integrated together. Some approximates from experience will be removed after all of the processes to be considered. This work is based on a virtual reactor. The goal is to improve precision by improvement of modeling and high fidelity computation. At present, study measures are changed from experiment and engineer dependent to theory analysis and numerical simulation. Numerical simulation will become more and more important. In this paper, CASL and NURESAFE are introduced. Then, several challenges, which include key technologies of software, are put forward in development of nuclear energy. Finally, suggestions are given for numerical reactor. It is only for reference and discussion. |
