3. NATURE OF PHYSICAL PROBLEM SOLVED

SHOSPA evaluates the hot spot factors for fuel and cladding as well as the hot channel factor as a function of the confidence level. Moreover, it evaluates the probability on n hot subassemblies. The code has been developed with emphasis on sodium cooled fast reactors, but it is applicable to any type of reactors constituted of bundled fuel rods with single phase coolant. An option for plotting is available in this version.

7. UNUSUAL FEATURES OF THE PROGRAM

In order to restrict the code to cosine axial power distribution, the FORTRAN functions FP and FC are not defined in the program, but they must be supplied by the user according to the actual axial profile as separate FUNCTION subroutines.
