3. DESCRIPTION OF PROBLEM OR FUNCTION

FUELS DATA is a collection of machine-readable fuel behavior data from domestic and foreign water  reactor test facilities developed for use in model verification of the Nuclear Regulatory Commission FRAP codes.

4. METHOD OF SOLUTION

Measurements have been formatted and stored to  facilitate computer application. The storage format for each fuel rod entry provides identification data, design parameters, power history, and corresponding measurement history. The verification data base is expanded prior to evaluating each new version of the model to enable verification runs to have continuing independent benchmark significance because there is always the chance that empiricism in the model based on previous experiments may be mis- directed.

The storage structure is made up of 11 separate file types, 10 of these corresponding to different card types and associated card formats. The identification and design block includes the first four card types: types 1, 2, and 3 appear for each entry. Card type 1 provides the rod designation and run number and experiment and reference report designation. Type 2 contains data availability flags for the 15 measurement parameters which follow and specifies the number of measurement locations. Type 3 represents the main design, fabrication, and system condition data. If local measurements are available, card type 4 gives the instrument location. Card types 5 and 6 describe the rod operation history. Type 5 specifies the heat rating and cumulative irradiation time at  the end of an operating step and the associated step power and burnup condition measurements. Type 6 describes normalized axial power distributions during different operation history periods. The  rod measurement history is defined by card types 7 through 11. Types 7 and 8 contain instrumented rod measurements corresponding to operating steps defined by card types 5 (e.g., integral measurements for fuel and cladding length change, rod internal pressure, fuel and cladding temperature, cladding circumferential strain, and gap conductance at specified instrument locations). Card types 9, 10, and 11 are used for post-irradiation exam (PIE) measurements. Types  9 and 10 contain integral measurements related to gas, void, pressure, and axial deformation conditions. Card type 11 represents  PIE measurements for melt radius, corrosion thickness, permanent hoop strain, and gap conductance from grain growth determination.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maxima of -
   70 operating steps
    5 axial power distribution profiles
    3 measurement locations
FUELS DATA contains only steady-state fuel behavior data.

6. TYPICAL RUNNING TIME

A formatted listing of the fuels data file can be produced using the editing program in about 20 CP seconds on  a CDC CYBER176 and 9 CP seconds on a CDC CYBER175. Approximately 6.5 CP seconds are required for a typical categorical processing run on  a CDC CYBER176 and 17 CP seconds on a CDC CYBER175.
NESC0844/02
NEA-DB executed the editing program on a CDC CYBER 740  using the test case data included in this package in 150 seconds of  CPU time.

8. RELATED AND AUXILIARY PROGRAMS

The FUELS DATA package contains an  editing program to read and print a formatted listing of the fuels data file containing measured data and design parameters for each data category. This fuel rod behavior data file was developed for model verification for the FRAPCON1 (NESC Abstract 694) and FRAP-T (NESC Abstract 658) programs.

11. MACHINE REQUIREMENTS

37,000 (octal) words of memory are used by the auxiliary editing program on a CDC CYBER175; 44,000 (octal) words of memory are required on a CDC CYBER176.
NESC0844/02
The editing program ran on CDC CYBER 740 in 44,000 (octal) words.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Each
edit subprogram is executed independently; a single input card is used to select the data category to be processed. Subroutine DUMPX produces a formatted listing for all data categories for approxi- mately 700 experiments.
A CDC UPDATE source file is also available for use by installa- tions having the CDC UPDATE utility. The file contains both program  and data and provides greater selection capabilities (i.e., specific runs may be compiled separately rather than the entire data set).
