Sellafield awards $6B ‘high hazard risk reduction’ framework contract
Sellafield Ltd., the site license company overseeing the decommissioning of the United Kingdom’s Sellafield nuclear site in Cumbria, England, has awarded a 15-year framework contract worth up to £4.6 billion ($6 billion) to support “high hazard risk reduction programs” at the site.

Samples of ethylene propylene diene monomer (EPDM) elastomer were exposed to tritium gas in closed containers at 101 kPa (1 atmosphere) pressure and ambient temperature for about one week. Tritium exposure effects on the samples were characterized by dynamic mechanical analysis (DMA) and radiolysis products were characterized by measuring the total final pressure and composition in the exposure containers at the end of exposure period. There was no effect of one week tritium exposure on the glass transition temperature, Tg, of the samples tested. Impurity gases produced in the closed containers included HT and lesser amounts of H2, DTO, and CT4. The total pressure remained the same during exposure.
