The scope of this research program is to study the structure of nuclei and the properties of the nuclear force, in particular its symmetries, using the tools of nuclear spectroscopy. To this end a unique set of instruments is at disposal, including curve crystal diffraction monochromators, high resolution beta spectrometers and Moessbauer spectrometers.

An increase in scandium-46 activity has been suggested as a possible cause of K Reactor rear face dose rates. The first investigations were initiated on {sup 46}Sc in 1968 after Environmental Evaluation, BNW, reported the increase in the {sup 46}Sc activity in the Columbia River. The first investigation was to verify whether or not there had been any increase in parent material ({sup 45}Sc) in the Columbia River. The resulting neutron activation data for river samples taken at Vernita during the latter part of 1968 and the first part of 1969 are compared with data obtained in 1962 by Silker. These data show that there was no increase in parent scandium since 1962. There also appears to be no seasonal increase in parent scandium as occurs with several other elements such as zinc. This latter observation (based primarily on the 1962 data) is quite puzzling since the BNW river data from samples taken near Richland show a definite seasonal trend. The BNW data are shown. Scandium-46 analyses of the reactor effluent water were initiated in March 1969 and these data also fail to show any significant seasonal trend of the magnitude shown by the BNW data. The reactor effluent data …
