The distribution of salinity in surface waters of the ocean is presented in Fig. 1.1. Because the concentrations for many major seawater constituents are unaffected by chemical reaction on the time scale of ocean circulation, local salinity distributions are controlled by a balance between two physical processes, evaporation and precipitation. This balance is reflected by low salinities in equatorial regions that result from extensive rain due to rising atmospheric circulation (atmospheric lows) and high salinities in hot diy subtropical g5Tes that flank the equator to the north and south (20-35 degrees of latitude) where the atmospheric circulation cells descend (atmospheric highs).

Saraiva et al [121] presented an extended model for a circulating atmospheric fluidized bed combustor (CAFBC) which included hydrodynamics for the fast section at the top of the bed as well a bubbling bed section at the bottom of the CAFBC. For the fast section of the bed, one dimensional momentum and energy balances were used to predict the temperature and velocity profiles for gas and particles throughout the reactor. The model contain species mass balances for five gas species including SO2, as well as a model of SO2 retention by limestone particles. A bubbling bed model was considered to simulate the chemical process at the bottom of the combustor.

The RVACS uses natural air convection to remove heatfrom the reactormodule. Atmospheric air is drawn into the reactor building and flows over the outside of the containment vessel. Radiative heat transfer drives cooling from the reactor vessel, through contairunent, and to the naturally circulating atmospheric air. Warm air then returns to a stack and is exhausted using the environment as the ultimate heat sink. The RVACS layout is shown in Figure 6.12. 

Heat removal systems 1) Gas-turbine system is used for normal core heat removal and transient deeay heat removal. 2) Cavity cooling system is the only safety-related system it removes reactor heat through reactor pressure vessel passively, by naturally circulating atmospheric air. 3) Auxiliary cooling system is a non-safety grade system used to shorten eooling time imder normal and accident transient conditions.
