Benzene/nitrous oxide flammability in the precipitate hydrolysis process

Description: The HAN (hydroxylamine nitrate) process for destruction of nitrite in precipitate hydrolysis produces nitrous oxide (N2O) gas as one of the products. N2O can form flammable mixtures with benzene which is also present due to radiolysis and hydrolysis of tetraphenylborate. Extensive flame modeling and explosion testing was undertaken to define the minimum oxidant for combustion of N2O/benzene using both nitrogen and carbon dioxide as diluents. The attached memorandum interprets and documents the … more

Program status 4. quarter -- FY 1989: Fusion technology development

Description: The ARIES-I design is nearing completion. The ARIES-II design work will begin soon and will be based on an advanced physics DT tokamak operating in the second stability regime. The ARIES-I blanket design team has selected the 5 MPa helium-cooled design as the reference blanket for study. Beryllium neutron multiplier will be used together with an advanced super-critical steam cycle for power conversion. Model ICRF tetrode tube anodes demonstrated the equivalent of plate dissipation, exceeding ex… more
