If only the weather was like this also this weekend as we're finalizing our week long film project, instead tropical storm Rafael has brought thunder storms, rain and heavy grey skies to our region and there's nothing else to do than sit inside, listening to the aggressive rain drops hammering on deck, drinking tea, eating tartelettes au citron and organizing the material that we have on hand. Hoping for the sun to reappear shortly but seems as we will need to wait at least 48 hours for that wish to come true. Our stay here in St Barts got a bit prolonged which has been very pleasant, and we shall be sailing Southwards later this upcoming week. If all goes as planned, we will be celebrating our three year anniversary as well as our two year anniversary for this World Tour on the beautiful private island of Mustique in the end of the month.
Both boiling water reactor and pressurized water reactor fuel assemblies consist of the same major components. These major components are the fuel rods, the spacer grids, and the upper and lower end fittings. The fuel assembly drawing on page 1-11 shows these major components (pressurized water reactor fuel assembly). The fuel rods contain the ceramic fuel pellets. The fuel rods are approximately 12 feet long and contain a space at the top for the collection of any gases that are produced by the fission process. These rods are arranged in a square matrix ranging from 17 x 17 for pressurized water reactors to 8 x 8 for boiling water reactors. The spacer grids separate the individual rods with pieces of sprung metal. This provides the rigidity of the assemblies and allows the coolant to flow freely up through the assemblies and around the fuel rods. Some spacer grids may have flow mixing vanes that are used to promote mixing of the coolant as it flows around and though t
