1. NAME AND TITLE

EVALPLOT: A Program to Plot Data in the Evaluated Nuclear Data File/Version B Format.

2. CONTRIBUTORS

IAEA, Vienna, Austria. The University of New Mexico, Albuquerque, New Mexico through the OECD Nuclear Energy Agency Data Bank, Issy-les-Moulineaux, France.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 3081 and Vax.

4. NATURE OF PROBLEM SOLVED

EVALPLOT is designed to plot cross sections in the ENDF/B format. The program plots cross sections, angular distributions, energy distributions, and parameters.

5. METHOD OF SOLUTION

In plotting cross sections, the program reads all sections of the file and divides them into five categories. The data are read and the interpolation law is checked; if the data are not linearly interpolative, an error message is printed and the program terminates. The data may then be linearized and the program rerun.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

The sample problem executed in 12.9 seconds.

8. COMPUTER HARDWARE REQUIREMENTS

The code was designed to run on the IBM 3081. Minor changes allow it to run on the VAX 8650.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required. No special requirements or restrictions are made on the operating system.
