Abstract |
: |
Neutron transition equation provide the exact account and correct for the distribution of neutrons in addition to the three-dimensional distribution in time and direction and energy. But it can not solve this equation analytically, except in limited cases and simple.
The matters must be applied to resolve the equation numerically. This is done by splitting the variables in the equation of neutron transition, ie, identifying the areas of dimensions, direction and energy to get a new version called the approximate equations of the specific angles of the multi-energy neutrons. In addition, it is necessary to resolve this new version, assuming the relations between the flux in the center ornament with the flux at the edges. In this research was the application of three types of divisions are the Diamond division and partition and partition the weighted non-linear offline. Diamond is a division of the simplest types of relationships, which provides acceptable results in the case of small cells, while the non-linear division offers online space with the results of different cells.
Due to the fact that this type of calculations and time-consuming, especially in the design of nuclear reactors and radiation shields to contain regions of high bounce, it should develop ways to speed up these accounts. One of these means Tangier acceleration diffuse Altaleva the best and most stable and effective, has been developed for many types of divisions in the one-dimensional. In the case of two-dimensional shapes has been enforced only with the diamond division.
In this research, the application acceleration diffuse Altaleva for the first time with all of the Diamond division and partition the weighted non-linear offline and using algorithms developed by the principal investigator on the earlier work. In addition, I use a form of linear accelerator in the case of diffuse Altaleva diamond division in order to avoid problems of non-linear format and to improve the speed of access to the results with large cells.
In short, the purpose of this research is to design a program on the computer to solve the equation of the specific angles of the multi-energy neutrons in the offline and the X and Y using the method of acceleration diffuse Altaleva Tksamesh of three methods of non-connected. |
