Abstract: A light water nuclear reactor melt-retention structure to mitigate the extent of direct containment heating of the reactor containment building. The structure includes a retention chamber for retaining molten core material away from the upper regions of the reactor containment building when a severe accident causes the bottom of the pressure vessel of the reactor to fail and discharge such molten material under high pressure through the reactor cavity into the retention chamber. In combination with the melt-retention chamber there is provided a passageway that includes molten core droplet deflector vanes and has gas vent means in its upper surface, which means are operable to deflect molten core droplets into the retention chamber while allowing high pressure steam and gases to be vented into the upper regions of the containment building.

Abstract: An animal additive for growth stimulation and lowering of feed consumption in accelerated fattening of domestic animals, has as an active agent a complex of inosine and an acid addition salt of dimethyl aminoisopropanol, or a mixture of these compounds. The compound or mixture may be used in the fattening of livestock, such as pigs, poultry, cattle, horses, sheep, dogs, and fish, and other animals. Particularly suitable is the complex of about 1 mole of inosine and about 3 moles of dimethyl aminoisopropanol.4-acetamino benzoate or the mixture of such ingredients in the indicated molar ratio.
