Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Compared with the serial or single nuclide ACE library preparation method, the distributed and parallel ACE library preparation method provided by the present invention is exactly the same as the former physical processing method, that is, the core is still to use the NJOY99 program to make ACE library, the main difference lies in the way of operation. Distributed jobs need to solve problems such as core database and input parameter preparation required by the ACE library, distributed job environment preparation and job submission, calculation result collection, and multi-temperature ACE library index generation. In addition, it is necessary to solve the identification problem of various files in the whole distributed operation process. The process of the whole technical solution is as follows: figure 2 shown, including the ...

Abstract

The invention relates to a manufacturing method of a distributed multi-temperature ACE warehouse. The core of the method is that ACE document is prepared by adopting an NJOY99 procedure, so that the purposes of preparation of NJOY99 input parameter, distributed operation environment preparation, operation submission, calculation result collection, generation of multi-temperature ACE warehouse indexing, identification of various documents, and the like in the ACE warehouse manufacturing can be achieved. The manufacturing method can be used for overcoming the defects of reduction of efficiency caused by the shortage of a serial method for exception handling, eliminating manual intervention and code rewriting in the manufacturing, promoting the calculation capability by sufficiently utilizing high-performance calculating clusters, and improving the ACE warehouse manufacturing efficiency and ACE warehouse manufacturing convenience.

Description

technical field [0001] The invention belongs to nuclear data technology, and in particular relates to a method for making a continuous energy point section library in ACE format. Background technique [0002] With the development of nuclear engineering design technology, Monte Carlo simulation of neutron transport process is more and more widely used in nuclear engineering. Correspondingly, the demand for the ACE format continuous energy point cross-section library (ACE library) matching the Monte Carlo program MCNP is also increasing. There are increasingly higher demands. [0003] The most basic way to make ACE library is to use the nuclear data processing program NJOY developed by Los Alamos National Laboratory (LANL). The current widely used version of this program is NJOY99 (see R.E. MacFarlane and D.W. Muir. NJOY99.0, Code System for Producing Pointwise and Multigroup Neutron and Photon Cross Sections from ENDF / B Data. Los Alamos National Laboratory, LA-12740 -M, 20...
