PARET code and the analysis of the SPERT I transients

The PARET code has been adapted for the testing of methods and models and for subsequent use in the analysis of transient behavior in research reactors. Comparisons with the experimental results from the SPERT-I transients are provided. The code has also been applied to the analysis of the IAEA 10 MW benchmark cores for protected and unprotected transients. The present version of the PARET code provides a convenient means of assessing the various models and correlations proposed for use in the analysis of research reactor behavior. For comparison with experiments the SPERT-I cores B-24/32, B-12/64, and D-12/25 were chosen. The results of this comparison of the PARET code with the SPERT I cores are generally quite favorable. The agreement with the B-24/32 core is particularly good. This core might be considered a more representative core for research reactors than either the B-12/64 or D-12/25 cores.
