In order to improve estimates of the effectiveness of current regulatory standards, a program was initiated by the US Nuclear Regulatory Commission (NRC) to have the Lawrence Livermore Laboratory (LLNL) evaluate regulatory standards against real world accident conditions. This paper presents the results of the evaluation performed for the hypothetical 30-foot drop onto an unyielding surface and real world impact conditions which might be experienced by a spent fuel cask being transported by a truck. The results of the evaluations performed for other pertinent accident conditions for truck and train transport will be documented at the conclusion of the program. 10 refs., 8 figs., 3 tabs.

The N30 lattice discussed in a previous note showed that a nearly matched lattice could be produced by separating four of the present quadrupole from their present power supplies and powering them separately. Although having significantly higher dynamic aperture, less closed orbit distortion and improved natural emittance compared to the present Aladdin lattice, the proximity of the {nu}{sub x} = 5.24 tune was felt to be too close to the 3{nu}{sub x} = 16 (a structure resonance) and the tune should be raised. In order to demonstrate the tunability of this modified lattice, Yang Cho found a new tune ({nu}{sub x} = 6.27, {nu}{sub y} = 6.23), hereafter called L2V2 lattice. This lattice, although not as nicely matched as the N30 lattice, has a 10% lower natural emittance and considerably more dynamic aperture. The L2V2 lattice has not been fully optimized, but is sufficient to demonstrate the advantages of this modified Aladdin lattice.
