Borosilicate glass (. alpha. ,n) sources used with ORIGEN-type calculations
The major part of the neutron source in vitrified high-level waste is produced from the actinide {alpha}-particle emission interacting with the light elements in borosilicate glass. Models applying thick target ({alpha},n) yield data have been developed for the ALPHN code and ORIGEN-S at the Oak Ridge National Laboratory. The method requires the relation between the ({alpha},n) yields and the stopping powers of elements, which are constituents in a mixture, and the total ({alpha},n) yield of the mixture. An example is given of results computed by ALPHN, listing the calculated ({alpha},n) sources for each {alpha}-particle emitter in addition to the total. An example computed by ORIGEN-S is given, showing both the total ({alpha},n) spectrum and the total neutron spectrum, including spontaneous fission. A discussion of the limited validation work is also provided.
