ABSTRACT\samples of six explosive c a m s (TNT, tetryl, NC, RCIX, W, I Pmn) and four e q l o s i v e mixtures were exposed to the neutron (and gamma) radiation f'ra a parer reactor a t integrated flux 1-1s of approximately l0'5 n/Cmo2 (5 x 10 re), ami 3 x d6 n/cm.* (2 x 10 r . In t h i s paper we present tho results of a pre1hiumu-y study of the effects of the comblned neutron and gcusma mdlatlon from a power reactor on ten organic explosive colPpounds eupd r&diures.

The detonation velocity of pressed TNT has been determined as a function of charge diameter at each of a series of loading densities ρ. Current theories of the diameter effect are discussed and used to compute infinite diameter detonation velocities (D∞) and detonation reaction-zone lengths from the experimental data. The results for the velocity-density dependence may be summarized as follows: D∞ = 1872.7 + 3187.2 ρ, (0.9 ≤ ρ ≤ 0.5342 g/cc); D∞ = 6762.5 + 3187.2 (ρ − 1.5342) − 25 102 (ρ − 1.5342)2 + 115 056 (ρ − 1.5342)3, (1.5342 ≤ ρ ≤ 1.636 g/cc). The reaction-zone lengths computed from the data are a decreasing function of the charge density and are in good agreement with predictions based on the grain-burning model of the reaction zone.
Two sizes of shipping containers for high explosives have been designed and tested at the Los Alamos National Laboratory. The containers have been tested by detonating a powerful, HMX-based explosive in the containers. The containers were approved for shipping 70% of the minimum weight of explosive that could cause vessel failure. I.
