【 摘 要 】

The Department of Energy (DOE) plans to build a Waste Solidification Building (WSB) at the Savannah River Site (SRS) in South Carolina. The project is currently in the preliminary design phase. In this scoping study surrogate radioactive concrete waste forms were prepared at water-to-cement mass ratios (w/c) of 0.2 and 0.3 and sealed in pressure vessels. Pressure and temperature were recorded electronically for the duration of the test. After about 11 days, the headspace gas of each vessel was sampled and analyzed by gas chromatography for hydrogen, oxygen, and nitrogen content. The data collected during these tests were used to estimate hydrogen gas generation rates and hydrogen G-values (molecules of hydrogen produced per 100 eV radioactive decay energy deposited) for waste forms prepared at each w/c ratio.
