Today, many nuclear power plants are realizing that they can save money and streamline operations by replacing larger, and more expensive, diaphragm pumps with smaller rotary gear pumps for the following reasons: Performance - Gear pumps are specifically designed to address high flow rates and deliver uniform, pulse-free dosing. Reliability – Chemicals such as sodium hypochlorite tend to off-gas when they come in contact with metal surfaces. However, non-metallic gear pumps feature a simple design that helps prevent off-gasing, which minimizes disruptions and helps to maximize uptime for water treatment operations. Safety - Because exposure to chemicals such as chlorine gas can cause respiratory issues for employees, great care should be taken to ensure that leaks do not occur when dosing hazardous chemicals. Sealless gear pumps offer fewer points of failure because there are no leak points for harsh chemicals to damage the pump or the surrounding equipment. Streamlined Maintenance – Easy access to the inner workings of a gear pump enables it to be maintained in place, which minimizes downtime by eliminating the need to lock out/tag out the pump and move it to the repair shop. The simpler the design is, the easier the pump is to maintain. This gives plant operators greater flexibility to schedule maintenance between shifts, or whenever it is least disruptive to do so. Smaller Footprint – Rotary gear pumps are compact in nature and they don’t require as many ancillary items as diaphragm pumps do (such as pulsation dampeners), so the overall size of the equipment package can be reduced.

BWR auxiliary feedwater valves in OTSG
Air-operated valves LCV-4025 and LCV-4026 control steam generator level for the “A” OTSG, and LCV-4007 and LCV-4009 for the “B” OTSG. The level control system for each valve receives a level input signal from a startup range OTSG level transmitter in the essential controls and instrumentation (ECI) system. This signal is compared with a level setpoint, and the resultant error signal modulates the control valve using a proportionalplus- integral controller. Manual control is available in both the main and auxiliary control room. Parallel flowpaths (one from a motor-driven pump, one from the turbine-driven pump) and redundant instrumentation and control power supplies for the level control valves ensure flow to each OTSG. Motor-operated block valves (V-14A and V-31B in the “A” OTSG supply, V-37A and V-20B in the “B” OTSG supply) provide redundant feedwater isolation of an OTSG. The turbine-driven and motor-driven pump discharge lines combine to supply the auxiliary feed ring in each OTSG.

Dow HDPE water pipe for nuclear power plant
As this was to be the first ever use of HDPE in a safety-related water pipe system at a nuclear plant in North America, the team at Callaway had to create a material specification and related procedures from scratch. In the process, they underwent a change in mindset from focusing on what was available to specifying what was really needed. Most importantly, Callaway engineers began to work closely with members of the HDPE pipe value chain. These players included The Dow Chemical Co. (Dow) as the HDPE supplier, WL Plastics Corp. as the pipe manufacturer, and Independent Pipe Products Inc. for the manufacture of special pipe fittings. The consultant, Frank Schaaf, Jr. of Sterling Refrigeration Corp., was also instrumental in the work necessary to gain approvals from the NRC. Callaway team selected CONTINUUM DGDA-2492 Bimodal Polyethylene Resin from Dow as the raw material for its new ESW secondary water pipe system. According to the team at Callaway, this installation is a first important step toward HDPE becoming a preferred material for safety-related water pipe systems at nuclear power stations. AmerenUE is already planning to replace other buried piping with HDPE in other systems in 2009.

Deoxygenation of Make-Up Water Using Gas Transfer Membranes
A deionized (DI) water storage tank is used at a nuclear power generation site in the United States. As a result, dissolved oxygen concentration in the plant make-up water was above specification. Retrofitting an existing vented tank to eliminate the vent and supply an inert gas blanket or mechanical seal is very expensive. Storage tank replacement can also be costly and may not be practical in terms of downtime and other factors. Because of these issues a GTM® system provided by Ecolochem, Inc. was installed to solve this problem. Ecolochem GTM systems utilize Liqui-Cel® Membrane Contactors manufactured by Celgard, LLC to remove dissolved gases from water streams.

On-Line Water Chemistry Measurements for Power Plants Ravi Jethra, Fred Kohlmann, Bhupen Patel, Endress + Hauser Inc. At the center of every efficient power plant, there is a well run water treatment system. Correct water treatment is crucial to provide high purity water to pre heater, boiler, steam and condensate systems, as well as other systems using boiling-water reactors and pressurized water reactors. The quality of makeup and feed-water is required to be monitored continuously to detect chaining water quality parameters (WQP). These changes in WQP usually indicate maintenance, upsets, leaks, and carryover. The long term data review of WQP also helps to study the gradual trends for prevention of corrosion or scaling. In case of inadequate measuring systems, these conditions may result in increased or unscheduled maintenance, higher capital cost, lower efficiency of heat transfer surfaces, and less profits due to down time. As newer and better technologies increase the power plant efficiencies in other area, the allowable limits on water quality become increasing important. Therefore, the requirements of WQP measurements become more important. The paper discusses data from case histories on water quality. In addition, the authors discuss how WQP measurements can be utilized to implement savings in reagents in the treatment process. The information presented in this paper would be helpful to operations managers, maintenance staff, and process owners of water treatments associated with power and steam utilities.

Power Industry Experience Using Micro Media Filtration and Short Bed Ion Exchange Geoff Hong, Eco-Tec Inc. With the demand for higher efficiencies and lower maintenance and operating costs for boilers and turbines, high purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra supercritical boiler pressures and temperatures, require such high purity water that it is approaching theoretical levels. High efficiency gas-fired combustion turbines, which use high purity water for NOx control and sprint mode, heat recovery steam generators and once through steam generators also require high purity water for the same reasons. Effective pre-treatment for reverse osmosis (RO) and ion exchange (IX) demineralizer systems not only contributes to the production of high purity water, but also helps to reduce the operating and maintenance costs of those systems. The versatility and efficiency of short bed ion exchange systems produce high purity water from feeds of variable characteristics, with lower chemicals consumption and waste volumes. This paper discusses the use of micro media filtration as a pre-treatment for RO or IX systems and the use of short bed IX systems for the production of high purity boiler feed make up water and condensate polishing. The experiences of several installations are outlined for applications in power generation and cogeneration plants.

RO Membrane Pretreatment Ken Robinson, Avista Technologies Pretreatment continues to be a subject that turns up on a daily basis when dealing with RO (Reverse Osmosis) process. Even though pretreatment requirements are well established for RO, the power utility market as a whole tends to see more of these issues as compared to other industries. Part of the reason for this trend is that feed water supplies tend to originate from surface sources while other factors tend to be more directed at equipment and design specifications. This presentation will focus on a number of pretreatment strategies that various power utilities have dealt with over the course of the last couple of years. RO system cases involving softening, coagulation, ultrafiltration, and media filtration will be covered along with RO process issues such as scaling, filtration, and biogrowth. In each of these cases, solutions will be presented on how to best mitigate the problems and show how analytical techniques can be used to fine tune and minimize the impact of the problems.

A New Approach to On-line Sodium Measurement David Gray, Mettler-Toledo Thornton, Inc. Sodium has been a critical measurement parameter for ensuring water treatment performance and purity for nearly four decades. Monitoring cation exchange performance and the purity of makeup water, steam and condensate has benefitted from measurement of this key parameter. Many refinements have been made to the ion-selective electrode method for on-line sodium measurement for these applications. Described here are yet further improvements to this technology including an unique integrated electrode system that measures both sodium and pH to assure proper reagent delivery. The system design minimizes reagent consumption and reduces maintenance requirements well below current practice. The new sodium system uses a particularly simple automatic calibration method and also provides the ability to measure grab samples easily. Its implementation with an operator interface common to other parameters including conductivity, dissolved oxygen, pH and ORP makes it especially convenient for installation and operator training.

Do Neutralizing Amines Have a Role in the Treatment of High Purity Boiler Feedwater? James (Jim) Robinson, Luis Carvalho, Robin Kluck, Richard Krichten, GE Power & Water – Water & Process Technologies Neutralizing amines have been widely used to treat high purity boiler feedwater since at least the 1940s. Notable benefits have been derived, however some consider the use of these amines to be risky. In addition the use of organic chemicals for boiler feedwater treatment often causes steam and condensate cation conductivity levels to exceed current power industry and steam turbine vendor guidelines. The benefits that can be derived and questions concerning the use of neutralizing amines are presented to help plant operators assess the potential value of using them in their systems.
