Available in PDF, EPUB and Kindle. Book excerpt: To determine the worst blast environments that eight types of expedient shelters can withstand, we subjected a total of 18 shelters to the 1-kiloton blast effects of Defense Nuclear Agency's DICE THROW main event. These expedient shelters included two Russian and two Chinese types. The best shelter tested was a Small-Pole Shelter that had a box-like room of Russian design with ORNL-designed expedient blast entries and blast doors added. It was undamaged at the 53-psi peak overpressure range; the pressure rise inside was only 1.5 psi. Expedient shelters of the types tested - especially if the ones with shored walls are equipped with blast doors - would afford better protection against the blast and fire effects of nuclear weapons and much better fallout protection than do all but a small fraction of existing buildings. Water storage pits lined with ordinary plastic trash bags were proven practical at up to 53 psi, as were triangular expedient blast doors made of poles.

It was undamaged at the 53-psi peak overpressure range; the pressure rise inside was only 1.5 psi. An unmodified Russian Pole-Covered Trench Shelter was badly damaged at 6.8 psi. A Chinese ''Man'' Shelter, which skillfully uses very small poles to attain protective earth arching, survived 20 psi, undamaged. Two types of expedient shelters built of materials found in and around most American homes gave good protection at overpressures up to about 6 psi. Rug-Covered Trench Shelters were proved unsatisfactory. Water storage pits lined with ordinary plastic trash bags were proven practical at up to 53 psi, as were triangular expedient blast doors made of poles.

Book excerpt: Oak Ridge National Laboratory field tests of expedient shelters during the past three years have resulted in the selection and development of six types of expedient shelters. These were demonstrated by construction exercises to be the most practical for average rural and small-town Americans to build in the principal environmental regions of the United States. Each type of shelter is designed to be built within 48 hours by average family groups of such Americans, using only widely available materials such as trees, to provide all members with high-protection-factor shelter. To evaluate the blast protection afforded by these six types of expedient shelters, they were blast tested as a part of Defense Nuclear Agency's Mixed bompany Event, in the blast area of a 500-ton TNT detonationequivalent in air blast effects to a 1.0 to 1.8 kiloton nuclear detonation. A total of twelve shelters, representing six expedient types, were subjected to blast effecta at surface overpressures ranging from 29 to 3 psi. All except the two Door-Covered Trench Shelters were tested as closed shelters. Only one shelter was damaged: the Door-Covered Trench Shelter that was tested as an open shelter at 5 psi. The six types of shelters. tested at the following measured surface overpressures, were: Two Small-Pole Shelters, at 29 psi; Three Wire-Catenary-Roofed Shelters, at 29 psi and 13 psi; One aboveground A-Frame Pole Shelter, at 17 psi; One Shored-Trench Stoop-in Shelter, at 13 psi; Two Log- Covered Trench Shelters, at 13 psi; and Two Door-Covered Trench Shelters, at 5 psi and 3 psi. Earth arching increased the strength of the shelters that had an adequate depth of earth cover relative to the roof span. A new design of quickly closable, expedient blast door was tested at 29, 17 and 13 psi surface overpressure ranges. Only the blast door at 17 psi was damaged, snd even it remained intact and securely closed. Also tested were two new designs of blast valves, both of which can protect against 100 psi overpressures and are closed in 1 to 2 milliseconds. One of these valves, the Overlapping-Flaps Blast Valve, requires only widely available materials and can be made in a few hours with common tools. (auth).

Book excerpt: The improved design of triangular entryway and blast door of hewn poles, tested at 304 kPa (44 psi), should provide dependable protection from large nuclear weapons at the 173-kPa (25 psi) overpressure range.

Available in PDF, EPUB and Kindle. Book excerpt: This report contains information on protective capabilities of a variety of different personnel shelters against prompt effects of nuclear weapons. This information was collected from previous studies performed for DCPA in this subject area. Protective capabilities are expressed in terms of 'people survivability functions' which relate the probability of survival (or percent survivors) to the free field overpressure at the shelter site. Respective shelters are described in terms of their geometry and material properties. The following shelter categories are included. (1) Existing Engineered Buildings (Upper Stories and Basements), (2) Designed Basements, (3) Single-Purpose Shelters, (4) Dual-Purpose Shelters, (5) Expedient and Special Purpose Shelters and (6) Expediently Upgraded Shelters.
