Patent number: 10847273Abstract: A steam separation system includes a standpipe configured to receive a gas-liquid two-phase flow stream and a diffuser configured to receive the gas-liquid two-phase flow stream from the standpipe. The diffuser includes a swirler configured to separate the gas-liquid two-phase flow stream. The swirler includes a plurality of swirler vanes and a straightener structure. The straightener structure includes a hub. The plurality of swirler vanes is mounted radially around the hub, and a straightener extends in an upward direction from the hub. The system also includes a separation barrel configured to receive the gas-liquid two-phase flow stream from the swirler. The separation barrel includes a rifled channel having orifices along an inner surface thereof. The plurality of swirler vanes is tuned with the rifled channel, such that an angle of each of the plurality of vanes corresponds to an angle of the rifled channel.Type: GrantFiled: January 17, 2014Date of Patent: November 24, 2020Assignee: GE-HITACHI NUCLEAR ENERGY AMERICAS LLCInventors: Phillip Glen Ellison, Adrian M.

Patent number: 10049775Abstract: In one embodiment, the steam separation system includes a plurality of steam separators configured to separate liquid from a gas-liquid two-phase flow stream; and a steam dryer system disposed above the steam separators. The steam dryer system includes a plurality of steam dryer bank assemblies and at least one moisture trap. Each of the steam dryer bank assemblies is configured to separate liquid of the gas-liquid two-phase flow stream exiting the steam separators. The moisture trap is disposed next to one of the steam dryer bank assemblies and is configured to remove liquid from the gas-liquid two-phase flow stream.Type: GrantFiled: April 29, 2014Date of Patent: August 14, 2018Assignee: GE-Hitachi Nuclear Energy Americas LLCInventors: Bulent Alpay, Adrian M.

Swirler, steam separator including the swirler, and nuclear boiling water reactor including the same
Patent number: 9916909Abstract: In one embodiment, the steam separator includes a standpipe configured to receive a gas-liquid two-phase flow stream, and a first swirler configured to receive the gas-liquid two-phase flow stream from the standpipe. The first swirler is configured to separate the gas-liquid two-phase flow stream. The first swirler includes a direct flow portion and an indirect flow portion. The direct flow portion has a direct flow channel for permitting direct flow of the gas-liquid two-phase flow stream through the first swirler, and the indirect flow portion has at least one indirect flow channel defined by at least one vane in the first swirler for providing an indirect flow of the gas-liquid two-phase flow stream through the first swirler.Type: GrantFiled: December 31, 2014Date of Patent: March 13, 2018Assignee: GE-Bitachi Nuclear Energy Americas LLCInventors: Adrian M.

Patent number: 8797021Abstract: An electrochemical corrosion potential (ECP) probe assembly for monitoring ECP in a high velocity reactor line includes an airfoil shaped ECP cover that improves the streamlines over and around an ECP sensor. The airfoil shaped cover includes flow holes drilled normal to the surface of the ECP cover. As such, the direction of flow of reactor water into the ECP probe assembly is altered to reduce the flow rate internal to the ECP cover sufficiently to prevent damage to the ECP probes. To facilitate use as a retrofit component, the ECP cover may have an elliptical section that is contiguous to a circular section that conforms to the geometry of existing probe wells and probe sub-assemblies.Type: GrantFiled: February 14, 2011Date of Patent: August 5, 2014Assignee: GE-Hitachi Nuclear Energy Americas LLCInventors: Theron D. Marshall, Adrian M. Mistreanu, Angelito Foz Gonzaga, John S. Bennion
