The RPS sends controlling signals -to the Control Rod Drive system to cause the actual insertion of control rods. The RPS is composed of two independent trip system-ns, "A" and "B." is initiated by the RF'S, the outlet scram valve Fig 02 C. When a Reactor scram signal (Fl 27) opens to vent the area above the piston to tihe scram discharge header and the inlet scram valve (F126) opens to admit pressure from the scram accumulator to the area below the CRD drive piston. The large differential pressure applied to the drive p:iston produces a large upward force on the index tube and control rod, inserting the rod into the Reactor. D. In order to scram the control rods, the scram pilot solenoid valves Fl 17 in trip system "A" and the Fl 18 valves in trip systenra "B" must both swap to the vent position (de-energize to vent). 1. Instrument air flows through all the scram pLlot air solenoid valves (137 each). In the non-scram condition, both scram pilot solenoid valves are energized, and instrument air holc3s the inlet and outlet scram valves closed. RPS trip system "A" supplies power to the Fl 317 valves, while RPS trip system "B" supplies power to the Fl 18 valves.. 2. Instrument air also normally flows through ttae backup scram valves (Fl 10A and Fl 101B), test valve (F008), and cne of the two scram air header pilot valves (F009 or F040). E. If a scram setpoint is exceeded in RPS trip system "A" only (commonly referred to as a half scram), the scram pilot soleno id valves in trip system "A" (Fl 17s) de-energize, but instrument air is still applied to the scram valves through the trip system "B" scram pilot solenoid valves (F1 1 8s), and the control rods would not scram.

  • Jordan Valve Product Overview
    PRODUCT OVERVIEW THE SLIDING GATE SEAT: A BETTER DESIGN SIMPLE CONCEPT, SUPERIOR PERFORMANCE You will notice something different in a Jordan valve . the sliding gate seat. A remarkably simple concept that offers superior performance and benefits not found in traditional rising stem and rotary valves. The sliding gate seat is made up of two primary parts: a movable disc and stationary plate with multiple orifices. Together, this seat set achieves levels of performance, reliability and accuracy that are hard to find in other valve designs. ADVANTAGES Quiet Operation Compared to conventional globe and cage designs, the sliding gate seat generates between 5-10dB less noise. You won't find a premium price adder for "low-noise trim!" The sliding gate valve is inherently quieter than other types of valves because: The disc and plate remain in constant contact, eliminating • the chatter found in globe-style designs "Massive" globe or The straight-through flow passage minimizes turbulence • cage style valve found in globe and rotary designs, a prime cause of valve noise • The multiple orifices in the plate and disc divide the flow into smaller flow streams resulting in less noise Smaller, lighter Size and Weight sliding gate wafer-design control valve As the line size increases, so too does the size and weight of the valve. Because of the short stroke length, a sliding gate valve is typically smaller and lighter weight than a globe/cage style valve. For the Mark 75 Series control valve, the shipping size, weight, packing waste and costs decrease dramatically due to the wafer style design.

  • Strategic Valve Locations in a Water Distribution System
    Strategic valve locations in a water distribution system Hwandon Jun Dissertation Submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Civil and Environmental Engineering G.V. Loganathan, Chair David. F. Kibler Vinod K. Lohani Antonio A. Trani Tamim Younos May 6, 2005 Blacksburg, Virginia Keywords: Water Distribution System, Valve, Segment, Matrix Algorithm, Simulation, Failure Analysis, Performance Indicators Copyright 2005, Hwandon Jun Strategic valve locations in a water distribution system Hwandon Jun ABSTRACT Valves play a critical role in a water distribution system for subsystem isolation and flow or pressure control. Among them, subsystem isolation is required to repair or to rehabilitate a broken component and can be done by closing adjacent valves. To evaluate the role of valves, the concept of “Segment” is necessary. A segment consists of a set of pipes and nodes isolated together by closing adjacent valves when a pipe fails. An efficient algorithm to identify segments in a water distribution system is proposed. In addition, when a segment is isolated, an additional subsystem may be disconnected from water sources by the segment isolation. It is a topological unintended isolation. In addition, a hydraulic failure, in terms of pressure types of failures at demand nodes should be considered. These three account for the failure impact of a pipe. Placing valves efficiently improves the reliability of a water distribution system. However, the valve reliability itself is not 100%. Therefore, valve failure consequence should be explored in determining the locations of valves.

    NRC INSPECTION MANUAL IRIB INSPECTION PROCEDURE 62710 POWER-OPERATED GATE VALVE PRESSURE LOCKING AND THERMAL BINDING PROGRAM APPLICABILITY: 2515 62710-01 INSPECTION OBJECTIVES The objective of this procedure is to provide guidance to inspectors to independently assess licensee conclusions regarding extent of condition of issues, when selected, as a part of supplemental inspections using IP 95002, AInspection for One Degraded Cornerstone or Any Three White Inputs in a Strategic Performance Area.@ The inspection procedure may also be used when power-operated gate valve pressure-locking and thermal-binding issues are applicable to each input contributing to a degraded cornerstone (2 white or 1 yellow) or to address extent of condition for any white input to the Strategic Performance Area that results in implementation of IP 95002. 62710-02 INSPECTION REQUIREMENTS The scope of the inspection using this procedure should be specifically focused on an independent extent of condition review and oversight of licensee self-assessment consistent with the objectives of IP 95002. The inspection plan should include one or more of the specific requirements listed below that are appropriate to perform an independent extent of condition review and oversight of licensee self-assessment necessary to assess the capability of power-operated gate valves in safety-related systems to operate under pressure-locking and thermal-binding conditions (or avoid such conditions) during normal, accident and abnormal conditions. The inspection may involve an in-depth review of calculations, analyses, diagnostic test results, modifications, and operating procedures used to ensure that proper operation of power- operated gate valves is not prevented by pressure-locking and thermal-binding conditions.

  • Diablo Canyon Part 21 Report Submitted 3/31/06
    FLOWSERVE May 25, 2006 U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Attention: Omid Tabatabai, Reactor Systems Engineer Subject: PG&E - Diablo Canyon Part 21 Report submitted 3/31/06 Reference: Request for Additional Information (copy attached) This letter is provided in response to the attached request and the conference call from 5/18/06. The background information is intended to provide a better understanding of the reasoning behind the Flowserve responses that follow. Background Information The reported valve is a replacement for valves originally supplied by the Anchor / Darling Valve Company (A/DV) in 1991. A/DV manufactured four 8" Tilting Disc Check (TDC) valves for Diablo Canyon. Two valves were supplied with an inspection port on the left side. Two valves were supplied with an inspection port on the right side. The inspection ports do not affect the valve operability. The Anchor/Dading Tilting Disc Check (TDC) relies on a counterweight to position the disc for closure. The counterweight is integrally cast to the disc. The basic operation of the TDC is as follows: * Flow in the direction of the flow arrow rotates the disc open. * The weight of the counterweight rotates the disc towards the seat as the flow decreases. * Flow in the direction opposite of the flow arrow drives the disc into the seat and provides the sealing force. The four TDC's for Diablo Canyon were originally manufactured based on the standard A/DV design. Two valves (one of each inspection port configuration) shipped in January of 1991. The standard design is supplied for a horizontal pipeline application.
