3D Rod Ejection Licensed Methodology

In June 2020, the Nuclear Regulatory Commission (NRC) finalized Regulatory Guide (RG) 1.2361 for plants evaluating the rod ejection accident (or reactivity-initiated accident [RIA]). The regulatory change is an enhancement of the precursor (RG 1.772 ) requiring a more detailed transient analysis that cannot be completed in the old onedimensional (1D) kinetics analysis methodology.

Acoustic Side Branch Technology

To resolve flow induced acoustic resonance in piping systems, Westinghouse can perform plant specific subscale testing to determine the source of the resonance and the optimal design change required to prevent it. For many plants, this design change involves the implementation of an acoustic side branch (ASB) in the existing piping system. Westinghouse has experience in testing and designing ASBs for several plants with flow induced acoustic resonances. The implementation of ASBs has proven to be an effective solution in reducing the magnitude of mechanical stress in the system and audible tones produced as a result of the resonance.

Advanced Plastics Processing Systems

The advanced plastics processing system (APPS) represents a new approach to plastics waste minimization in nuclear power plant waste treatment and in other areas where radioactive waste arises. Some customers currently sort plastics waste in sorting boxes, place it into compactable drums and then compact or supercompact it. Because compacted plastic has a deformation memory, “spring back” results after compaction, making it difficult to achieve optimal waste reduction. A Westinghouse APPS installation is based on proven techniques that are currently used in the plastics industry worldwide. Westinghouse innovates to enhance them for the nuclear application. Maximum waste reduction is achieved without changing the chemical composition of the plastics.

Advanced Rod Control Hybrid

The Westinghouse Solid State Rod Control System (SSRCS) has been in operation at many plants for over 30 years. This system has been very reliable but obsolescence concerns are increasing and personnel experience for the analog control system is difficult to maintain in the modern, digital world. The system also has limited diagnostics and can be time consuming to troubleshoot, increasing downtime.

Advanced Scale Conditioning Agents

The accumulation of deposits in the secondary side of steam generators (SGs) increases the potential for accelerated tube degradation and flow oscillations. As these deposits harden and form crevices, they can cause conditions that lead to tube corrosion. To improve upon traditional mechanical deposit removal techniques and avoid the potential drawbacks of traditional SG chemical cleaning, advanced scale conditioning agent (ASCA) technology was developed in 2000.

Aging Management and License Renewal Support Services

Aging management is a technical process that provides reasonable assurance that the aging of important nuclear power plant systems, structures and components (SSC) is being managed so they will continue to perform their intended function(s). Outside the United States, the aging-management process is being utilized to confirm the aging-management elements of the International Atomic Energy Agency’s (IAEA) Periodic Safety Review (PSR) process. Most member states require a PSR review once every 10 years for continued plant operation. In the United States, the aging-management process provides compliance with the requirements for obtaining a renewed operating license. License renewal is a regulatory process that allows a nuclear plant in the United States to extend its operating license for an additional 20 years (beyond the 40 years of its original license). Whether applied to the PSR or license renewal, this process provides an extremely cost-effective way to assure available generation capability into the future.

CEDM High Temperature Coil Stack/Gripper Coils

Combustion Engineering (CE) Control Element Drive Mechanism (CEDM) coils have been in use for more than 40 years with a respectable operating history. However, the upper gripper coil, which is normally energized continuously in order to hold the control rod at the full out position, has been found to be under particular stress. As a result, the CE CEDM upper gripper coil is prone to early failures, accelerated by excessively high voltage or exposure to temperatures above its design value.

CEDM High Temperature Gripper Coils

Westinghouse has developed replacement Combustion Engineering (CE) Control Element Drive Mechanism (CEDM) High Temperature (HT) Upper and Lower Gripper Coils that have much higher temperature capability than the original CEDM gripper coil design. CE CEDM coils from the standard CE design have been in use for more than 40 years with a respectable operating history. However, the upper gripper coil, which is normally energized continuously in order to hold the control rod at the full out position, is under particular stress. As a result, the CE CEDM Upper Gripper Coil may fail after several years of service. Its failure is accelerated by excessively high voltage or exposure to temperatures above its design value.


If radioactive liquid or solid waste needs to be converted into a product suitable for final storage, cementation is one of the methods commonly used. Cement is readily available and inexpensive for use in solidifying liquid or wet solid waste, and also for encapsulating solid waste generated during operation of a power plant as decontamination and decommissioning waste and legacy waste. Using cement for immobilizing radioactive waste offers a wide range of possibilities for optimizing the properties of the final end product. Recipes for the end product can be tailor-made to suit particular waste streams – from the highest possible compression strength to the maximum amount of waste at a certain level strength – combined with low leachability.

Chamber Filtration

Removal of particles from liquid waste is one of the most important steps in liquid radioactive waste treatment to get rid of particle-bound activity and protect downstream processes. The Westinghouse chamber filtration system consists of a chamber filtration unit, a feed tank with pump, a permeate tank with pump, a filtration additive tank with pump and a reject system with a Westinghouse-design docking station for the drums. Chamber filtration can tolerate various solid concentrations and build up its own filter layer; therefore, it is particularly well suited for sludge and other similar fluid mixtures. Filter additives can be used, if necessary and no filter cartridge waste is created.

Containment Integrated Leak Rate Test Extension

In 1995, the U.S. Nuclear Regulatory Commission (NRC) provided an Option B to Title 10 Code of Federal Regulations (CFR) Part 50, Appendix J, which is a performance-based approach to leakage testing requirements that allows licensees with acceptable test performance history to change surveillance frequencies. Addressed with the performance-based approach are the surveillance frequencies for Type A, B and C tests. The Type A test assesses the overall leakage of containment. The Type B test assesses leakage for containment penetrations. The Type C test assesses leakage for containment isolation valves. At that time, provisions were made for extending the Type A test (integrated leak rate test [ILRT]) frequency from 3-in-10 years to 1-in-10 years.

Since the late 1980s, industry data has consistently identified the feedwater system as one of the top two major system contributors to the number of automatic reactor trips, with poor feedwater control as a significant root cause. In response, Westinghouse has provided leading feedwater control upgrade technology as the basis for numerous retrofits currently operating in dozens of nuclear units worldwide, dating back to its first wave of digital upgrades in the late 1980s that initially utilized the WDPF® Instrumentation and Control (I&C) platform.

Filtered Containment Venting: The Dry Filter Method

Safe and expedient pressure release from reactor containment to the atmosphere must occur so that containment integrity can be maintained if pressure builds up in containment during a severe accident. A filtered containment venting system (FCVS) is necessary to perform such a containment depressurization effectively while minimizing the radioactivity released into the environment.

Fire Probabilistic Risk Assessment (PRA)

A Fire PRA is required to implement plant transition to NFPA 805, as well as to meet NRC Regulatory Guide (RG) 1.200 requirements (i.e., technical adequacy of PRA results for risk informed activities). NFPA 805 is a standard developed by the National Fire Protection Association that provides a risk-informed, performance-based alternative to a plant’s current fire protection program. NUREG/CR-6850 is the NRC-endorsed guidance for developing a Fire PRA that meets the Fire PRA Standard, ANS 58.23.

Hot Resin Supercompaction

The Westinghouse Hot Resin Supercompaction (HRSC) process is applied for volume reduction of organic bead and/or powder resin. It was developed more than 20 years ago to address the specific waste characteristics of one nuclear power plant. The presence of both powder and bead resins was considered in developing the process to address the needs of both pressurized and boiling water reactors. The most critical issue for a successful process configuration is the duroplastic behavior of resins, in particular of the bead resins. This behavior prevents the resins from building a homogenous, solid block and, in the worst case, bursting the metal surface of the pellet, known as the spring-back effect. Various laboratory and full-scale trials had to be performed to adjust the process parameters to address this issue.

Hydrogen Production Capabilities

The Westinghouse Solution Westinghouse is committed to bringing efficient, large-scale hydrogen production to nuclear facilities through operating plant integration and advanced reactor designs.

In-drum Dryer

Drying processes are used for volume reduction of liquid radioactive waste. The final product of this process is a solid waste product. The Westinghouse in-drum dryer dries liquid, non-combustible waste such as evaporator concentrates. During the drying process the solid content in the drum increases and precipitates while the liquid is evaporated and condensed subsequently. By falling below a certain drum filling level, liquid waste is automatically re-dosed. The drying process is complete once a certain condensate flow is no longer reached. The result is a quality dry product that can withstand long-term storage without chemical or biochemical reactions occurring over the subsequent storage period.

Independent Review of Probabilistic Risk Assessment

Westinghouse provides an independent review of probabilistic risk assessment (PRA) program studies to help customers show that their PRAs meet applicable technical-quality requirements. Per Revision 2 of Regulatory Guide 1.200, PRAs used for risk-informed regulatory applications must meet certain technical adequacy and quality requirements, as determined by the American Society of Mechanical Engineers (ASME) and the American Nuclear Society (ANS) PRA Standard (RA-S-2008).

Integrated Hydrogen Monitoring Solutions for Severe Accidents

Background During a severe accident or a beyond-design-basis accident (BDBA), the reaction of water with zirconium alloy fuel cladding, radiolysis of water, molten coriumconcrete interaction (MCCI) and post-accident corrosion can generate hydrogen (H2). The total mass of H2 produced in-vessel depends on several factors. For most reactors, it is on the order of 1,000 kilograms. High peak rates for H2 release to the containment of up to several kg/s can result from discontinuous releases from the reactor pressure vessel. The detonation of H2 can result in damage to structures such as containment buildings or spent fuel buildings. In all reactor designs, H2 monitors can be utilized to monitor the risk of containment or spent fuel building damage due to H2 detonations.

Integrated Outage Model

The delivery of commercially competitive, reliable, zero-emission clean and sustainable energy, with unparalleled safety and flexible operations, are Westinghouse’s key goals.

License Renewal Implementation

With nuclear power plants (NPPs) extending their licenses, there is a large backlog of work that must be performed prior to entering the period of extended operation. After the U.S. Nuclear Regulatory Commission (NRC) grants a plant a new license, the plant must fulfill a significant number of commitments before entering the period of extended operation. To satisfy all the commitments, many smaller tasks must be completed. Reductions in staff and a subsequent loss of experience are issues when completing the required commitments.

LOCA Safety Analysis Services

A loss-of-coolant accident (LOCA) is an inadvertent loss of inventory from the primary side of the reactor coolant system (RCS).

Local Fuel Duty Risk Monitor

Pellet clad interaction (PCI) is a serious concern for operation of nuclear power plants under transient conditions such as those that occur during startup, temporary down power for maintenance activities, load follow or dropped rod recovery. Under these conditions, fuel failure can occur if the core is ramped too quickly. However, the definition of “too quickly” depends on fuel operating history; thus, if a single “rule of thumb” ramp rate is used it will be necessarily conservative and the plant will be delayed in getting maximum power on to the grid.

Long Duration Energy Storage (LDES)

Pumped Thermal Energy Storage (PTES): Engineered to Fill the LDES Gap to Enable the Global Energy Transition.

Long-Term Operations

To keep your plant operating for the long-term, you need to think beyond the problems of today. To empower your colleagues, your neighbors and your community to reach your net-zero goals, you need strategic solutions that will elevate your capabilities for whatever comes next. Your organization must make critical investment decisions based on a variety of factors – from economic, infrastructure and material to social and political conditions. But to keep your plant running successfully into the future, you need more than an investment plan – you need a partner.

Low Power and Shutdown Probabilistic Risk Assessment Modeling for Pressurized Water Reactor Plants

The increased focus on probabilistic risk assessments (PRAs) and risk-informed applications by the U.S. Nuclear Regulatory Commission (NRC) has led utilities to expand their PRA model update efforts. Their efforts have initially focused on updating the Level 1 and Level 2 PRA models for the internally initiated events.

Low Temperature Zinc + Platinum Deposition (LT-ZiP)

Chemical decontamination is routinely performed to remove activated corrosion products from boiling water reactor (BWR) plant piping while simultaneously reducing plant dose rates. This process was developed for commercial use in the early 1980s, and has since been successfully applied by Westinghouse to more than 300 BWR system decontaminations.

Low- and Intermediate-level Radioactive Waste Management

Westinghouse has extensive global experience in the design, licensing, construction supervision and operational support of low- and intermediate-level radioactive waste management facilities. The types of facilities that process both low- and intermediate-level radioactive waste typically must meet two fundamental objectives: providing immediate and deferred protection for both people and the environment and allowing the site to eventually be used freely and without radiological limitations. Westinghouse design for the disposal process is based on a multiple-barriers system that accomplishes both objectives.

Peripheral Power Suppression Assembly

Industry studies indicate that the reactor pressure vessel may be a limiting component with respect to attaining the desired life and life extension (i.e., long-term operation/subsequent [second] license renewal [LTO/SLR]) for many nuclear power plants. The primary reactor vessel life attainment issue is concerned with the prevention of nonductile failure of the reactor vessel welds, which are subject to neutron radiation-induced embrittlement effects. For those vessels where this concern exists during their anticipated operational life, the implementation of neutron flux reduction programs can play a significant role in attaining desired reactor lifetimes. Because fluence impacts to these welds build up over time, effective fluence reduction requires implementing a program as early as possible to minimize the amount of incremental fluence reduction needed in each future cycle after program implementation (see graph).

Permanent Cavity Seal Rings – Narrow Gap and Wide Gap

The annulus gap between the reactor vessel and the containment cavity floor must be sealed to permit the flood-up required for refueling and reactor internal maintenance activities. This sealing is accomplished by installing a temporary pool seal into the annulus gap. The installation of these “temporary” seals is a critical path process that lengthens outage duration as well as increases worker exposure. These seals have also been known to experience leakage, which negatively impacts both outage and normal operation processes.

Phased Array Examinations of Reactor Vessel Nozzle Dissimilar Metal Welds

Operators of Pressurized Water Reactors (PWRs) with reactor vessel (RV) nozzle dissimilar metal (DM) safe-end welds, which are susceptible to primary water stress corrosion cracking, are required to examine those welds with increased frequency unless mitigating actions are taken.

Plant Protection System

The plant protection system monitors plant temperatures, pressures, levels, flows and nuclear instrumentation system outputs. If these parameters exceed plant safety limits, the system issues “partial reactor trip” and “engineered safeguards” commands. The plant protection system sends isolated analog output signals to the plant control system, the data processing and monitoring system, and the main control board. It also provides alarm outputs to the plant annunciator system. The plant protection system can be supplied with an interface to the data processing and monitoring system, or implemented as a standalone upgrade to the existing plant system. When supplied with an interface, a phased approach permits small stand-alone upgrades to be eventually integrated into a total plant information network.
