It is pertinent to the safety case for geological disposal in the UK that the behaviour of vitrified wastes in proximity to cementitious materials is understood. In this study, vitrified simulant intermediate level nuclear waste (ILW) was subject to dissolution in a synthetic cement water solution to simulate disposal conditions. Results show that the presence of alkali / alkaline earth elements in the cementitious solution can be favourable, at least in the short-term, leading to lower dissolution rates associated with incorporation of these elements into the altered layer of the glass.

OBJECTIVES/SPECIFIC AIMS: Synthetic cannabinoids (SC) are widely available and are associated with acute psychosis. Our recent study indicated that SC using psychiatric inpatients admitted in 2014 had more psychotic symptoms, aggression, and agitation compared with cannabis [marijuana (MJ)] using patients. The current study will review more charts and will characterize the demographics and presentations of current SC Versus MJ using patients. METHODS/STUDY POPULATION: A chart review was conducted of patients admitted to a New York City inpatient dual diagnosis psychiatric unit from 2014 to 2016. Inclusion criteria were self-reported current SC use or MJ use, or urine toxicology (+) for MJ. RESULTS/ANTICIPATED RESULTS: In total, 585 charts met inclusion criteria, 168 reported current SC use (40 f, 128 m SC users; 122 f, 295 m MJ users). SC using patients were younger (p=0.050), more likely to be Black (p=0.003), and homeless or living in a shelter (p=0.001). SC users were also more likely to be agitated (OR: 2.26) and aggressive (OR: 2.04) and have psychotic symptoms (OR: 3.03) compared with MJ users. SC users received more PRN medication (p<0.001) and had longer lengths of stay (p=0.001). DISCUSSION/SIGNIFICANCE OF IMPACT: Results demonstrate that current SC users had a different demographic profile compared with current MJ users. Our results also support our previous findings: SC using patients were more likely to be agitated and aggressive and were more likely to demonstrate positive psychotic symptoms.

The dissolution of a soda-lime silicate glass in two cement leachate compositions, Young Cement Water (YCW) and Ca(OH)2, was investigated, as an analogue for dissolution of vitrified nuclear waste in a cementitious geological disposal facility. Dissolution was performed at repository temperatures (50°C) and under CO2-exclusion. Dissolution rates were observed to be a factor of 20 times higher in YCW than in Ca(OH)2, as result of the high potassium content of YCW solutions. The precipitation of the zeolite phase, K-phillipsite (K(Si,Al)8O16·6H2O), is thought to be responsible for elevated dissolution rates. Conversely, in Ca(OH)2 solutions, the precipitation of calcium- and silica-containing phases, such as tobermorite (Ca5Si6O16(OH)·4H2O), acted to reduce rates of dissolution by forming a barrier to diffusion. These results show that dissolution of vitrified nuclear waste materials in a cementitous repository may be significant during the early stages of cement leaching in groundwater.

This study details the characterization of a glass sample exposed to hyperalkaline water and calcium-rich sediment for an extended time period (estimated as 2 - 70 years) at a lime (CaO) waste site in the UK. We introduce this site, known as Peak Dale, in reference to its use as a natural analogue for nuclear waste glass dissolution in the high pH environment of a cementitious engineered barrier of a geological disposal facility. In particular, a preliminary assessment of alteration layer chemistry and morphology is described and the initiation of a long-term durability assessment is outlined.
