NUCLEAR REACTORS AND EARTHQUAKES

Description: A book is presented which supplies pertinent seismological information to engineers in the nuclear reactor field. Data are presented on the occurrence, intensity, and wave shapes. Techniques are described for evaluating the response of structures to such events. Certain reactor types and their modes of operation are described briefly. Various protection systems are considered. Earthquake experience in industrial and reactor plants is described. (D.L.C.)

A SUMMARY OF INDUSTRIAL ACCIDENTS IN USAEC FACILITIES

Description: The accident experience of the AEC contractor operation for 1959 and 1960 is reported. Incidents involving radio active materials are described. A table of inadvertent criticality was included to supplement other tables. A tabulation of exposure records at values from 0 to 15 r is given. (M.C.G.)

VARIATIONS IN ISOTOPIC CONTENT OF NATURAL URANIUM

Description: Uranium ore concentrates from seventeen world sources were compared to a standard to determine variations in isotopic content. A spread of about 0.06% in U/sup 235/ content was indicated for the concentrates analyzed. Domestic sources showed much wider variations than those from other parts of the world. (auth)

Hydrogen Production in the Calcium and Magnesium-Nitric Acid Reactions (Deleted Version)

Description: For greater understanding of possible explosion hazards, data are needed of the volume of H/ evolved in the Ca and Mg reactions with nitric acid. Nearly five liters of H/sub 2/ per mole of Ca are produced when 16M nitric acid reacts with Ca metal. The hydrogen evolved slowly increases with decreasing nitric acid to below 4M nitric acid, when a rapid increase occurs. The Mg--nitric acid reaction produces only one liter of H/sub 2/ per mole of Mg with 2M nitric acid, and the volume of H/sub 2/ decreases with increasing nitric acid concentration. (L.T.W.)

ZIRCEX URANIUM SUBLIMATE LOSS

Description: One of the limitations of the Zircex Process is the large percentage loss of U which is carried off with the volatile ZrCl/sub 4/. Since the ratio of U to Zr in the fuel element is quite small (< 1%), a large percentage of U loss can be caused by small amounts of U in the ZrCl/sub 4/ sublimate. The U loss must be kept below 1% if the Zircex Process is to be adapted to industrial scale processing. (W.L.H.)

DISPERSION OF SOLUBLE RADIOACTIVE MATERIAL IN WATER

Description: Theories of diffusion processes in water are discussed and the dispersion of radioactivity is calculated from an interpretation of the molecular diffusion equation with modifications which tend to fit the equation to from fission products in solution are made for a number of situations of interest. Parametric solutions are obtained and plotted on graphs which may be used to obtain water concentrations and thence dose levels. (auth)
