Containment hatches

Containment closure capabilities - The confinement function must be maintained while the fuel in the core (the containment hatch may be open, but must be possible to re-close if necessary - TS to ensure containment integrity while at mid-loop - Administrative controls on containment integrity - Requirement to keep the containment equipment hatch closed during the mid lop operation from the removal of the SG manway to installation of the last nozzle dam ... 

Minimise the off-site consequences The confinement function must be maintained wfrile the fuel in the core ( the containment hatch may be open, but must be possible to re-close if necessary before a core damage is to occur). 

Example 10 Calculation of Multicomponent Batch Distillation A charge of 45.4 kg mol (100 Ih-mol) of 25 mole percent heuzeue, 50 mole percent monochlorohenzene (MCB), and 25 mole percent orthodichloro-henzene (DCB) is to he distilled in a hatch still consisting of a rehoiler, a column containing 10 theoretical stages, a total condenser, a reflux drum, and a distillate accumulator. Condenser-reflux drum and tray holdups are 0.0056 and... 

Some of the ultrasonic systems include ultrasonic transmitters that can be placed inside plant piping or vessels. In this mode, ultrasonic monitors can be used to detect areas of sonic penetration along the container s surface. This ultrasonic transmission method is useful in quick checks of tank seams, hatches, seals, caulking, gaskets or building wall joints. 

Solanoeclepin A (39), a natural hatching agent of potato cyst nematodes, possesses a seven-membered ring in a complex pentacyclic framework. Hiem-stra and coworkers achieved the synthesis of several analogs 42 containing the... 

Figure 2.60 Pictorial representation of the SLIC scheme showing the updating scheme for an upwind and a downwind cell. Cells filled with fluid 1 are indicated in gray, those with fluid 2 in white. Cells containing a mixture of both fluids are represented by hatched areas. In the right column the configuration at the new time step is shown, with interface positions depicted explicitly.

Figure 1.61. Paleobathymetry of the NE Japan Are at 17-14 Ma (circled numbers) (Yamaji, 1990). The arc subsided rapidly from 16 to 15 Ma. The entire inner arc region became at middle bathyal depths until 15 Ma, except that Yuri hill remained at shallow marine depths. The hill was submerged until 14 Ma (Matoba, 1981). Stippled area, Aosawa basalt (Tsuchiya, 1988). Hatched area, Yuri hill. Note that submarine volcanoes are neglected in this figure because volcaniclastic rocks usually contain few fossils.

Larvae of the yellow fever mosquito, which are shallow feeders, were reared at room temperature by methods similar to those used in culturing Anopheles mosquito larvae (2, 6). Filter papers containing the eggs (furnished through the courtesy of R. E. Heal, Merck Co., Inc., Rahway, N. J.) were placed in tap water in shallow porcelain pans (12 X 7 inches, and 2 inches deep). The eggs hatched within 24 hours. When the larvae had hatched, powdered dog biscuit was added daily at the rate of 100 mg. per liter of water. 

Figure 3. Sketch of DDC-expressing neurons in the Drosophila larval CNS. The CNS consists of brain lobes and a segmented ventral ganglion. Filled circles represent dopamine cells open circles represent serotonin cells grayed circles represent DDC cells that contain no detectable tyrosine hydroxylase or serotonin immunoreactivity, indicating that these cells may produce neither transmitter (Lundell and Hirsh, 1994). M, medial dopamine neurons VL, ventrolateral serotonin neurons DL, dorsolateral dopamine neurons. The hatched rectangle shows the region of the ventral ganglion that is shown in Figures 4 and 6.

Fig. 4 Survey spectrum of sputter-cleaned Hf metal containing 3% Zr impurity, with all visible core-line peaks labelled, collected using a monochromatic A1 Ka X-ray source (1486.7 eV). The stepped background hatched), found in all XPS spectra, arises from photoelectrons that lose KE by inelastic electron scattering as they travel through the surface and into vacuum...

Eggs of the Jefferson salamander (Ambystoma jeffersonianum) from a series of ponds that contain 1 to 25 pg Cu/L have — at the higher copper concentrations — a reduction in hatching success and an increase in embryonic mortality (Home and Dunson 1995). 

Eggs were exposed in freshwater to 4 pg Ag/L for 14 days prior to hatch. After hatching, larvae were exposed to 4 pg Ag/L in salt water for 14 days during yolk-sac resorption. Fry were then transferred to uncontaminated salt water and fed a high metals diet for 64 days (diet At end of study, experimentals had a small, but significant, decline in survival. Just prior to transfer to uncontaminated salt water, experimentals contained 62 pg Ag/kg whole body DW vs. 4 in controls. After 64 days in uncontaminated salt water, whole alevins contained 18 pg Ag/kg DW vs. 4 in controls 29...

Figure 5. Ca + bioavailability to mice. The animals were administered by gavage 200 ul of 0.1 mM (cross-hatched) and 1.0 mM CaCl2 (dotted) containing variable amounts of phytic acid as indicated on the abscissa. The mean and standard deviation of 4 to 9 determinations of Ca2+ absorption into the blood after 4 hours are shown on the ordinate. (Reproduced with permission from Ref. 26. Copyright 1984 J.
