General Atomics

GAMESS stands for general atomic and molecular electronic structure system (we reviewed a version dated Dec. 2, 1998). It is an ah initio and semiempirical program, and has seen the most widespread use for ah initio calculations. The ASCII input hie format is usable but somewhat more lengthy than some other programs. The fact that GAMESS is a free, high-quality software makes it a favorite of many academic researchers.

Many problems have been reported (163), and the process has been abandoned because of the difficulty in handling sohds. Processes which are thought to have the best likelihood of success ate based on sulfuric acid decomposition. Three prominent cycles are based on this reaction the General Atomics iodine—sulfur cycle...

The HTGR designed by the General Atomic Company and constructed at Peach Bottom, Pennsylvania, U.S.A., was a 40 MW(e) experimental power plant which was similar in many respects to the Dragon reactor. Peach Bottom started commercial operation on June 1, 1967, and ceased operation on October 31, 1974 [36]. The major performance parameters of the Peach Bottom Reactor are shown in Table 8.

We have mentioned (p. 9) that, in general, atoms of the second row of the periodic table do not form stable double bonds of the type discussed in Chapter 1 (n bonds formed by overlap of parallel p orbitals). However, there is another type of double bond that is particularly common for the second-row atoms sulfur and phosphoms. For example, such a double bond is found in the compound H2SO3, as written on the left. Like an ordinary double bond, this double bond contains one s...
