'water rod' is not grammatically correct and should not be used as it is in written English.
A better way to say this would be 'watering rod.' You can use this phrase to refer to a long implement used to water plants like a garden. For example, "I went out to buy a watering rod so I can water my plants more easily."
The book is a marvelous account of the author's passion for a scaly, chunky, long-lived denizen of lakes, ponds and streams over much of the world that is usually caught -- sometimes after 12 hours or more of lounging, back against a tree, line in water, rod propped up with a forked stick -- with a hook baited with kernels of canned corn, canned beans, balls of dough or bits of bread.
Both the coolant in water rod and fuel channel flows up and is mixed at the upper plenum.
Four test cases for a high burn-up 8 × 8 fuel bundle with a single water rod were simulated using CFX-10 for the microscopic void distribution benchmark.
In Advance Heavy Water Reactor (AHWR, ECCSS is designed to inject water from a central water rod of the fuel bundle in form of jets to rewet hot surface of fuel pin.
The results show that, by means of reducing the gap size between fuel rods, the heat transfer coefficients between coolant and fuel rod, as well as the heat transfer coefficient between coolant and water rod, would both increase noticeably.
Figure 4 illustrates the background found in a cold water rod which is located in a phantom homogeneously filled with F, I or Y.
By investigating samples after etching, but previous to cleaning with water, rod-like crystals on the NiTi surface were detected.
Two rows of fuel rods are filled between the water rods in the fuel assembly.
Large water rods are introduced to preserve the moderating power and to accommodate finger type control rods.
Each fuel assembly is made up of four sub-assemblies with downward-flow water rods, which is favorable to the core cooling during abnormal conditions due to the large water inventory of the water rods.
Three different SCWR concepts SCWR-M, American SCWR and SSCWR are respectively selected as the representations of multi-pass core, one-pass core with water rods and one-pass core without water rods.
