Progress in assessing the effect of ionizing radiation on the anticipated waste package environment at the Yucca Mountain potential repository site

PDF Version Also Available for Download.

Description

Progress in establishing the effect of ionizing radiation on the expected air/water vapor waste package environment is summarized. This work was performed at Argonne National Laboratory (ANL) in support of the Yucca Mountain Site Characterization Project. The radiolytic issues that have been identified are presented. Long-term gamma experiments with gas compositions ranging from dry air to high-humidity air were completed. The predominant nitrogen fixation products in all air-like systems studied were nitrogen dioxide and nitric acid. Yields between 0.8 and 2.3 molec/100 eV have been measured. Ammonia formation, although not predominant, was also observed at temperature below 100{degrees}C. The ammonia ... continued below

Ammonia formation, although not predominant, was also observed at temperature below 100{degrees}C. The ammonia yields were low, and the concentration did not build up with increased absorbed dose. The status of the issues identified is given.
