1. NAME AND TITLE

INDRA: A Modular System for Calculating the Neutronics and Photonics Characteristics of a Fusion Reactor Blanket.

DATA LIBRARIES

DLC-2: Neutron Cross Section Data.

DLC-7: Evaluated Photon Interaction Library

DLC-12: POPLIB-Secondary Gamma-Ray Yield and Cross Section Data.

ENDF/B: Evaluated Nuclear Data File.

The INDRA system was contributed several years ago (1977) and has not been currently updated. More recent data in each of the above categories is available in RSIC. To use them will necessarily require changes to the code system.

2. CONTRIBUTOR

Max Planck Institute for Plasmaphysik, Federal Republic of Germany.

3. CODING LANGUAGE AND COMPUTER

FORTRAN IV; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

INDRA is a program system allowing a complete evaluation of the neutronics and photonics characteristics of fusion reactor blankets including neutron and gamma-ray heating rates, tritium breeding and other reaction rates of interest.

5. METHOD OF SOLUTION

Uncoupled calculation of neutron and gamma-ray transport by well-established discrete ordinates codes. Preparation of reaction cross-sections by proven computer codes. Auxiliary programs for evaluating and managing the final results. Data transfer between program modules mostly by magnetic tape.

6. RESTRICTIONS OR LIMITATIONS

This version of INDRA permits only one-dimensional calculations to be performed. Further restrictions are set by data availability.

7. TYPICAL RUNNING TIME

Running time depends heavily on the size of the problem. It is different for the single modules. For the sample problems, the following running times were needed: SUPERTOG-332 sec; MACK2 min; GROUCO1 sec; APRFX32 sec; TREVED1 min; DRP2 sec; TAPEMAKER2 sec; DTFMF2 sec; DTF-IV4 sec; ANISN4 sec; CROSS1 sec; POPMAKER1 sec; POPOP41.5 sec; MUG1 min; GAMSO1 sec; GLUCKE1 sec; FLUZI5 sec; GLOUMAN3 sec.

8. COMPUTER HARDWARE REQUIREMENTS

The code was designed to run on the IBM 360/370 Operating System.

9. COMPUTER SOFTWARE REQUIREMENTS

A FORTRAN IV compiler is required.
