Consultant's Meeting on
New Evaluated Data File Processing Capabilities

5 - 9 October 2015, IAEA, Vienna

Background

The ENDF-6 format is the currently adopted universally format for storing evaluated nuclear data. However, such data representation is seldom directly usable in application codes. Processing of the data is less trivial than it seems, as demonstrated through the ' Code Verification Project conducted by D.E. Cullen through the IAEA many years ago. As a result, many codes were simply abandoned. Apart from some local codes, the main survivors for basic data processing and for generating application libraries were PREPRO, NJOY and AMPX. Unfortunately, the PREPRO package is limited to the basic operations on nuclear data, while NJOY and AMPX are subject to some restrictions in the distributions.

Motivation

The motivation for the Consultants Meeting is to help steering the Agency's development efforts in the field of nuclear data to better serve the users in Member States. There is a strong desire in Member States to have access to "open source" data processing system that would be well maintained and would avoid the danger of "common mode failure" due to all data processing done with the same set of processing tool, and to enhance the development of data processing capabilities for the emerging alternative data representation formats such as the GND format.

Objectives

Review available nuclear data processing codes, discuss their status, availability, define the necessary development work and the means of implementation, and expected assistance from the IAEA (CRP, DDP, CSA, CM, informal information exchange, etc.)

Agenda

The Agenda is available here.

Codes

The list of well known processing codes is given below.

• NJOY99, NJOY2012
• AMPX
• Fudge
• PrePro2015
• GRUCON
• CALENDF
• Other ...

Work to be done

In preparation for the meeting the participants should prepare answers to the questions listed below. The current status is available in the Questionaire document.

• What is the end purpose of your data processing activities?
• Which application code uses your processed data (is it open source, available on request or classified)?
• What is the processed data format?
• What are the characteristics of the group structure if preparing data for deterministic codes?
• What is the status of your code (e.g.: open source, available on request, classified, under development, etc.)?
• If enhancement of the open-source data processing capabilities is undertaken through the IAEA, are you willing
to contribute your software?
• Which are the data processing modules of highest priority that are not available as open-source software?

By the end of the Meeting a list of data processing codes used in different laboratories and their status should be assembled.

A list of modules should be prepared, where improvements are most urgently needed (in terms of methods, code availability, etc).

Summary Report

The summary report INDC(NDS)-0695 is available.
