![]() Inside the reactor pressure vessel (RPV), the coolant first flows down outside the reactor core (through the downcomer). The primary circuit of typical PWRs is divided into 4 independent loops (piping diameter ~ 700mm), each loop comprises a steam generator and one main coolant pump. The water (coolant) is heated in the reactor core to approximately 325☌ (⍴ ~ 654 kg/m 3) as the water flows through the core. Inlet temperature of the water is about 290☌ (⍴ ~ 720 kg/m 3). 16MPa). At this pressure water boils at approximately 350☌ (662☏). Pressurized water reactors are cooled and moderated by high-pressure liquid water (e.g. It is an illustrative example, data do not represent any reactor design. It is an illustrative example, following data do not correspond to any reactor design. See also: Fluid Acceleration – Pressure Loss It differs by about 9% and therefore ice floats on liquid water It has a maximum of density at 3.98 ☌ (1000 kg/m 3), whereas the density of ice is 917 kg/m 3. For example, water differs from most liquids in that it becomes less dense as it freezes. It must be noted, there are exceptions from this rule. Where ∆T is the change in temperature, V is the original volume, ∆V is the change in volume, and α V is the coefficient of volume expansion. The change in volume of a material which undergoes a temperature change is given by following relation: This phenomenon is known as thermal expansion. However, the amount of expansion or contraction varies, depending on the material. Most substances expand when heated and contract when cooled. The effect of temperature on the densities of liquids and solids is also very important. Compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change. On the other hand, the density of gases is strongly affected by pressure. The effect of pressure on the densities of liquids and solids is very very small. Increasing the pressure always increases the density of a material.
