Many redundant safety features were provided at the SRP. These included a moderator dump tank, gadolinium nitrate solution as emergency absorber, continuously mnning diesel generators, and a 95 x 10 -L (25 x 10 -gal) elevated water tank for each reactor, for assurance of cooling.

Larvae of amphibions flee and hide in response to waterborne chemicals from predators (Kats et al. 1988 Kats 1988 Petranka et al. 1987). Run water through a flow-through system of four consecutive tanks from a water tank to a tank with predator fish, to a tank with tadpoles, and finally to a water tank. For the control experiment, there are no fish in the second tank. Observe and measure the spatial distribution and the shelter-seeking by the tadpoles under three conditions in the second tank is no fish a predatory fish and nonpredatory fish.

Ideally, a plant of this size is started up in stages, so that replacement will be a continuous process. Membranes in all the 10 packs of a press are generally renewed at the same time. A reserve of 10 assembled packs can be kept in a water tank for immediate installation. If necessary, a single pack in a press can be renewed at any time, although this complicates the maintenance schedule. The reserve press on the plant, which could serve either stage I or stage II, was used when a press was being serviced. 

The Virus House was finished in October. Besides a laboratory the structure contained a special brick-lined pit, six feet deep, a variant of Fermi s water tank for neutron-multiplication studies. By December Heisenberg and von WeizsScker had prepared the first of several such experiments. With water in the pit to serve as both reflector and radiation shield they lowered down a large aluminum canister packed with alternating layers of uranium oxide and paraffin. A radium-beryllium source in the center of the canister supplied neutrons, but the German physicists were able to measure no neutron multiplication at all. The experiment confirmed what Fermi and Szilard had already demonstrated that ordinary hydrogen, whether in the form of water or paraffin, would not work with natural uranium to sustain a chain reaction. 

Solar dryers applying a water tank for heat storage have an indirect heat transfer system the working medium of the collector is liquid (e.g., water) and the drying air should be preheated in a liquid-air heat exchanger. Two different constructions are discussed below. 

Pumps are required in the feed system either to transfer product within the feed systan or to supply product to the atomizer. The pumps in the spray-dryer feed system are sized and selected for each application depending on the type and properties of the feed material and also depending on the atomizer incorporated in the feed system. When rotary atomizers or two-fluid nozzles are used, low-pressure pumps are also usually used. When pressure nozzles are employed, high-pressure pumps are required [34]. Various types of pumps are used because of the variety of feed materials that are encountered (see Table 52.6). A water tank for dryer startup and shutdown is mounted on the atomizer feed pump. 

After sampling the aggregate in accordance with CEN EN 932-1 (1996) and reducing the amount in accordance with CEN EN 932-2 (1999), a representative portion of dry coarse aggregate is placed in the wire basket, which is then immersed in a water tank for 24 0.5 h, at 22°C 3°C. The minimum mass per test portion required is given in Table 2.12. 

Flow times of polymer solutions were measured using a Ubbelohde capillary viscometer. Relative viscosity (j]x) was obtained from the ratio of the flow times of a solution and the solvent. Before each measurement, a solution in the viscometer was sealed and allowed to equilibrate with a thermostatted water tank for at least 20 min. The temperature fluctuation of the water tank was smaller than 0.1 °C. All samples used for flow time measurements were clarified by filtration through Millipore 0.45 xm PTFE filters. Each polymer solution was measured for three times so that the relative error was less than 0.2 %.
