Web31 de mar. de 2024 · Results demonstrate that RELAP-7 has the capability to model different regimes encountered in two-phase flow with wall boiling, superheated steam, subcooled liquid and condensation. RELAP-7 also has the capability of modeling different fluids with their own specific models in a very flexible way, without any code change. Web31 de jul. de 2024 · Hi! I'm a bit curious, what would happen if there would be a leakage in the condenser in a nuclear plant (PWR or BWR). As I understood it the stean in the turbine is expanded to about 4 kPa and I guess the pressure outside in the freshwater that is pumped into the condenser is at atmospheric pressure.

Web8 de fev. de 2024 · In the BWR, the pressure in the reactor vessel is about 1000 psia; the water boils in the reactor vessel and the steam is passed directly from the reactor vessel to the turbine. A PWR uses chemical shim (borated water) to maintain a critical configuration (the control rods that drop from the top are basically for rapid shutdown).
