Liquid level measurement system comprising an improved condensing chamber design |
摘要 |
<p>The disclosed apparatus includes a condensing chamber (CC) that maintain 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). The reference leg (RL) connection provides a flow path for the CRD drive water system backfill to flow into the condensing chamber (CC) and overflow into the variable leg (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 condensing chamber (CC) to the reactor pressure vessel (RPV) in a substantially continuous manner, thereby tending to prevent the introduction of non-condensable gas enriched liquid from the condensing chamber (CC) into the reference leg (RL) and improving the tolerance and reliability of the level measurements and/or reducing thermal stresses on the various condensing chamber (CC) connections.</p> |
