“…The software uses a peak shape inspired by the Hypermet [19,24] and Hyperlab [25] programs, and also incorporated in the Hypergam package [26,27]. This model is valid for all regular peaks in the PGAA spectrum, with the exceptions discussed hereafter.…”

Special spectrum regions, like around the annihilation peak at 511 keV, the boron peak at 478 keV, the Ge-triangles, as well as complicated multiplets or heavily distorted intense peaks require special attention when evaluating Prompt-gamma Activation Analysis (PGAA) spectra. A computer code and the related analytical practice of the Budapest PGAA facility is presented to improve the spectroscopy of these cases beyond the past practice relying on the well-known Hypermet-PC software.

“…The results show that HyperGam performed similarly to other commercial programs in terms of its ability to detect small peaks on a low background. When the threshold values of "SIG" for the peak search and "RSIG" for the residual test [3] were lowered to (3, 2), (2.5, 2), (1, 1), the number of small hits increased to 42, 51 and 102, respectively, while the number of false hits increased accordingly to 3, 7, and 12.

The method for the establishment of an equilibrium core model proposed in the previous paper and the source term calculation method proposed in this paper for the characterization of decommissioning waste were verified by comparing the nuclide inventory estimated by MCNP/ORIGEN2 simulations with the measured nuclide inventory according to a chemical assay in an irradiated pressure tube discharged from Wolsong Unit 1 in 1994. At first, the time-average pseudoequilibrium full-core model of Wolsong Unit 1 was developed on the basis of the previously proposed modeling method for the activation of in-core and ex-core structural components. Then, the application level of the neutron flux and cross section in the radionuclide buildup calculation were compromised. Fourteen major actinides and fission products were considered to represent the irradiated fuel condition, and a geometry simplification was also introduced in the burned full-core model for MCNP simulation. The assumption of a constant neutron flux and capture cross section as a function of the irradiation time was applied in the radionuclide buildup calculation in ORIGEN2. As a result, the values estimated from the analysis system agreed with the measured data within a difference range of 30%. Therefore, it was found that the MCNP/ORIGEN system and source term characterization method proposed can be viable to estimate the source terms of the decommissioning waste from a CANDU reactor.
