F.C.D.A. Family Shelter Evaluation

Description: In order to determine the effects of atomic explosions on small civil defense shelters for family use, 29 simple structures were built along an arc 1200 ft from the target point and exposed to Buster Bursts B, C, and D. The structures were of four basic types; covered-trench, metal-arch, wood-arch, and basement lean-to. Because of poor cohesive properties of the soil, much of the earth cover on the shelters was removed by the first shot. Since test procedures prevented restoration of structures… more

Laundered protective clothing survey

Description: It is considered appropriate occasionally to make independent checks on the effectiveness of the plant laundry in removing radioactive contamination from plant-issue protective clothing. Previous surveys have offered constructive criticism resulting in improved handling of high level and soft beta contaminated clothing and incorporation in new designs of ventilating and air sampling recommendations. Recurrently the adequacy of laundry reject limits is questioned, and only recently an accurate, … more

Effect of design changes and operating conditions on combustion and operational performance of a 28-inch diameter ram-jet engine

Description: The results of an altitude test-chamber investigation of the effects of a number of design changes and operating conditions on altitude peformance of a 28-inch diameter ram jet engine are presented. Most of the investigation was for a simulated flight Mach number of 2.0 above the tropopause. Fuel-air distribution, gutter width, the presence of a pilot flame, cimbustion-chamber-inlet temperature, and exhaust-nozzle throat area were found to have significant effects on limits of combustion. Combu… more

Altitude performance of annular combustor type turbojet engine with JFC-2 fuel

Description: An investigation was made comparing the performance of JFC-2 fuel and unleaded, clear gasoline in a 3000-pound-thrust turbojet engine. The JFC-2 fuel was a blend of percent diesel fuel and 25 percent aviation gasoline. Engine combustion efficiency was equal to that obtained with gasoline at rated engine speed and altitudes up to 35,000 feet, but at lower engine speeds or at higher altitudes the JFC-2 fuel gave lower combustion efficiency. No discernible difference was obtained in starting or lo… more

Evaluation of Military Individual and Collective Protection Devices and Clothing

Description: Under conditions resulting from surface and underground detonations of atomic bombs, tests were conducted on Chemical Corps impregnated and unimpregnated protective clothing, Individual Protective Mask M9A1 with M11 Canister, Tank Collective Protector E26 and E22, and Protective Ointment M5. Both impregnated and unimpregnated clothing were capable of preventing contact between the skin and radioactive dusts. Unimpregnated clothing demonstrated better contanmination-decontamination characteristi… more

BRIQUETTING OF MACHINED PLUTONIUM TURNINGS FOR RECYCLE TO THE CASTING OPERATION. Final Report-Production Test 235-6

Description: Twenty-four briquettes of Pu turnings were pressed in a He atmosphere and made into eight castings. Six castings were processed to final form and were comparable to normally processed material. Two castings were recy-cled due to causes other than briquetting. Casting y-ieids. (wt. of casting/wt. of briquettes). were approximately 90%; approximately 10% of the Pu in the briquettes remaining in the melting and pouring crucible as skull. (auth)
