The only large-scale use of deuterium in industry is as a moderator, in the form of D2O, for nuclear reactors. Because of its favorable slowing-down properties and its small capture cross section for neutrons, deuterium moderation permits the use of uranium containing the natural abundance of uranium-235, thus avoiding an isotope enrichment step in the preparation of reactor fuel. Heavy water-moderated thermal neutron reactors fueled with uranium-233 and surrounded with a natural thorium blanket offer the prospect of successful fuel breeding, ie, production of greater amounts of (by neutron capture in thorium) than are consumed by nuclear fission in the operation of the reactor. The advantages of heavy water-moderated reactors are difficult to assess. 

Effective with the 1982 model year, particulate matter from diesel vehicles was regulated by the U.S. Environmental Protection Agency for the first time, at a level of 0.37 gm km . Diesel vehicles were allowed to meet an NO level of 0.93 gm km under an Environmental Protection Agency waiver. These standards were met by a combination of control systems, primarily exhaust gas recirculation and improvements in the combustion process. For the 1985 model year, the standards decreased to 0.12 gm of particulate matter per kilometer and 0.62 gm of NO per kilometer. This required the use of much more extensive control systems (1). The Clean Air Act Amendments of 1990 (2) have kept the emission standards at the 1985 model level with one exception diesel-fueled heavy trucks shall be required to meet an NO standard of 4.0 gm per brake horsepower hour.

The next presentations discussed chemical problems encountered in the nuclear power industry. S. R. Hatcher (Atomic Energy of Canada Ltd., Pinawa) gave a general review covering the chemistry of established and novel nuclear fuels, heavy-water production, and reactor operation. 

This process is used to produce light gases, naphtha, distillate fuel, heavy fuel oil, and petroleum coke by cracking heavy residual products such as atmospheric and vacuum resids. Both delayed coking and fluid coking processes are utilized. 

Macrocrystalline wax is larger in size and typically contains waxes from 17 to approximately 30 carbons in length. Plate structure wax is macrocrystalline in form and can be found in low concentration in some distillate fuel. Heavy distillates and residual oils can contain higher concentrations of macrocrystalline wax. 

The plant in Figure A.4 can be dealt with in exactly the same way. The reformer and the two fuel cells would be elevated to IT/SOFC conditions, as in Figure A.6. All surplus fuel, heavy hydrocarbons and unoxidised fuel from the three plant sections, together with three hot exhausts, would be swallowed by a gas turbine combustion chamber as above. That would yield a controllable plant, subject to availability of semi-permeable membranes and of isothermal concentration cells, appropriate to IT/SOFC temperatures and gas turbine pressure.

Heavy industrial gas turbines are usually to be found in refineries, chemical plants and power utilities. They are chosen mainly because of their long and reliable running times between major maintenance overhauls. They are also capable of burning most types of liquid and gaseous fuel, even the heavier crude oils. They also tend to tolerate a higher level of impurities in the fuels. Heavy industrial machines are unsuitable for offshore applications because -...

Other types of reactor fuels that are fabricated include heavy water reactor fuels, research reactor fuels, navel fuels, and mixed oxide (MOX) fuels. Heavy water reactor fuels fabrication is much the same as light water fuels with the exception that the assembly configuration is different and the uranium can be of natural enrichment due to the increased moderation provided by the heavy water. Navel fuel fabrication and configuration processes are classified, although it is generally understood that the fuel is metallic and highly enriched, similar to some research reactors. 

The Gas-to-Liquid (GTL) process is an attractive technology to produce high-value fuels (heavy w-alkanes, a-olefins etc.) based on the Fischer-Tropsch (FT) synthesis. According to this synthesis, a mixture of H2 and CO is converted into liquid hydrocarbons according to the general chemical reaction ...
