Abstract: A retainer (20) for retaining a grid (17) on a fuel assembly. The retainer (20) has at least one aperture (26) at one end thereof for receiving a shoulder on a guide control tube and legs on the other end thereof for welding to the grid. The one end of the retainer is captured between the shoulder and a surface on the bottom nozzle of the fuel assembly when the guide tube is attached to the bottom nozzle. The retainer reduces the rotation of the guide tube resulting from torquing of the screws which connect the guide tube to the bottom nozzle thereby increasing the integrity of the assembly.

Abstract: A video system (24) which monitors the position of the target member (14) with a camera (20) and provides an output signal commensurate with the target displacement. The camera is mounted near the target for generating a composite video signal including the target and a region (12) extending along the direction of movement of the target. A video signal converter (24) is associated with the camera and includes means for separating the video signal into horizontal and vertical digital data points. The vertical data points define an arbitrary vertical axis (84) which is aligned with the direction of target movement. The displacement of the target is determined by electronically counting the number of vertical data points, or scan lines, between a reference position of the target and a displaced position of the target along the column of vertical data points. In the rotameter embodiment, the number of scan lines in the converted video signal are counted between the no-flow reference position of the target and the target as the target moves or changes in the flow rate. Preferably, a video monitor (30) is associated with the converter for generating an image display to the user. The converter injects a vertical line (40) on the calibration monitor that helps the user align the "counter" column of video data points with the target path (84).

Abstract: The system (12', 14) includes a target member (78) associated with the stem valve (24) and displaceable therewith, and a camera (68) adapted to be positioned adjacent the stem for generating a video signal of at least a portion of the target member. A marker (80) associated with the valve in the field of view of the camera is provided for defining a reference displacement scale (82) in the video signal. A converter (62) is responsive to the video signal for generating target data commensurate with the absolute displacement of the target. First data interface means (42, 58, 60) are provided for digitizing the sensed pneumatic pressure as the pressure is changed to displace the stem, preferably a full stroke from the open-to-close-to-open positions or vice versa. Second data interface means (44, 62) are provided for digitizing the target data commensurate with the displacement of the target. In a preferred embodiment, the displacement of the target member (78) is determined by electronically counting the scan lines or sequence of pixels (92-108) associated with the video signal, which are covered or uncovered, or otherwise interrupted, as the target member is displaced.

Abstract: The steam generator water level, the feed water temperature, and the reactor power are continuously measured and a level signal (76), a temperature signal (78), and a power signal (80) commensurate with these measurements are respectively generated. From the power signal and the temperature signal, a target flow signal (84) is generated corresponding to the feedwater flow rate that would produce a stable steam generator water level at the steady state condition of the power signal and the temperature signal. The level signal is compared to a level signal setpoint (54) and a resulting level error signal (86) is generated. The level error signal is adjusted by a gain factor (88) that is dependent on the temperature signal to produce an adjusted level error signal (90). The feedwater flow through the bypass valve is then controlled in response to the target flow signal (84') and the adjusted level error signal. In a preferred implementation of the invention, the transition between low power control using the bypass valve and high power control using the main feedwater valve is accomplished by generating a main valve position signal (118), and generating an enable signal (124) when the power signal is within a desired transition power range. When the power is in the transition range, the feedwater flow through the bypass valve is ramped down or up in response to the target flow signal, the adjusted level error signal, and the main valve position signal, as the main feedwater flow increases or decreases.
