Industrial equipment survival/recovery feasibility program during event DICE THROW. Final report
Inexpensive techniques for protecting industrial equipment from nuclear attack environments hold great promise for permitting early repair of industrial machinery and its restoration to production following an attack. Without protection, typical industrial machines suffer 'moderate' damage at about 5 psi and 'severe' damage at about 10 psi. Equipment items representative of fragile machinery, normal machinery and rugged machinery were tested at 40, 80, 200, and 600 psi in the DICE THROW field test event excuted October 6, 1976. The test specimens were placed in trenches excavated at the four appropriate ranges from the DICE THROW explosive charge center. The specimens then were surrounded by a crushable material (aluminum chips) and covered at depths from one foot to five feet with earth material removed in excavating the trenches. The results of these experiments indicate that with the use of crushable fill and with burial depth sufficient to permit earth arching, machines can be protected against overpressures up to 600 psi. However, when depths of covering were too shallow for an earth arch to develop, severe damage occurred.
