Stallmann, F W

LSL-M2 is a package of computer programs for the adjustment of neutron spectra in nuclear reactors based on the combination of neutron transport calculations and radiometric or other integral dosimetry measurements and their uncertainties in the form of variances and correlations. The underlying algorithm is a least squares logarithmic statistical estimation procedure. Spectra at several different locations can be processed simultaneously which increases the accuracy of the adjusted values and allows the adjustment of spectra at locations without dosimetry. The primary output is adjusted damage parameter values (e.g., fluence > 1.0 MeV and dpa) with uncertainties. The code is written in standard FORTRAN-77 and has been tested for the DEC-10 and the IBM-PC/AT. Requests for the computer code and associated data files should be made through A.
