    • The disclosed apparatus includes a condensing chamber (CC) that maintains a volume of a condensate obtained from vapor emitting from a vessel, for example a reactor pressure vessel (RPV). The condensing chamber is connected to a reference leg (RL), a variable leg (VL) and a vapor or steam leg (SL). RL connection provides a flow path for the CRD drive water system backfill to flow into the CC and overflow into the VL. The excess backfill and/or condensate will be returned to the vessel, typically at a point below the liquid level within the vessel. Non-condensable gases will thereby be returned from the CC to the RPV in a substantially continuous manner, thereby tending to prevent the introduction of non-condensable gas enriched liquid from the CC into the RL and improving the tolerance and reliability of the level measurements and/or reducing thermal stresses on the various CC connections.
    • 所公开的设备包括冷凝室(CC),其保持从容器(例如反应堆压力容器(RPV))发射的蒸汽获得的冷凝物的体积。 冷凝室连接到参考腿(RL),可变腿(VL)和蒸汽或蒸汽腿(SL)。 RL连接提供了CRD驱动水系统回填流入CC并溢出到VL中的流路。 多余的回填物和/或冷凝物将返回到容器中,通常在容器内的液面以下。 因此,不可冷凝的气体将以基本上连续的方式从CC返回到RPV,从而倾向于防止将不可冷凝的富含气体的液体从CC引入RL并提高液位测量的公差和可靠性, /或降低各种CC连接上的热应力。
