Water bar with two compartments for boiling water reactors.

摘要

A FUEL HARBOR (B) IS PRESENTED FOR A NUCLEAR BOILING WATER RECTOR WHICH HAS AN IMPROVED ROD (W), THIS WATER ROD HAS TWO DISCRETE COMPARTMENTS, ONE UPPER COMPARTMENT (14), TO CONTAIN WATER. THE BOTTOM COMPARTMENT (17) FLOWS THE MODERATOR FROM THE BOTTOM OF THE FUEL HARNESS (B) THROUGH THE WATER ROD COMPARTMENT TO THE DISCHARGE POINTS (20) LOCATED THROUGH THE SIDE WALLS OF THE WATER ROD AMONG THE SEPARATORS LOCATED ABOVE (S); THE UPPER COMPARTMENT (14) OPENS TOWARDS THE DOWN PART (15) AND IS NATURALLY FILLED WITH MODERATING LIQUID ADJUSTING THE FLOW UPWARD OF THE MODERATOR DURING THE OPERATION OF THE REACTOR. THIS RESULTS THAT THE PRESENCE OF THE MODERATING LIQUID WITHIN THE WATER ROD (W) IS REQUIRED FOR THE SUPPLY OF THE UPPER TWO-PHASE ZONE OF THE FUEL HARNESS (B) WITH ALMOST COMPLETE MODERATOR DENSITY. AT THE SAME TIME, THE FLOW OF WATER THROUGH THE WATER ROD FROM THE BOTTOM OF THE FUEL HARNESS TO THE TOP OF THE TWO-PHASE REGION OF THE FUEL HARNESS IMPROVES THERMAL, HYDRAULIC PERFORMANCE. SPECIFICALLY, THE WATER IS DISCHARGED IN THE UPPER REGION OF TWO PHASES OF THE FUEL HARNESS IN THE CENTER OF THE FUEL HARNESS WHERE THE DENSITY OF THE MODERATING LIQUID THAT FLOWS UP HAS THE GREATEST STEAM FRACTION. AS A RESULT OF ALL THIS, THE MODERATOR IS INJECTED WHERE IT HAS THE MAXIMUM BENEFICIAL EFFECT ON THE DENSITY OF THE MODERATOR AND THE BENEFICIAL FORMATION OF A LIQUID FILM JUST ABOVE THE SEPARATORS (S). THE RESULT IS A HYDRAULIC THERMAL PERFORMANCE OF THE FUEL HARNESS (B).
