Valve Testing, Engineering and Flow Services
Using a unique combination of advanced analysis and testing tools, GVIRL provides integrated solutions to valve and actuator O&M challenges. Our credentials include more than two decades of nuclear valve qualification and recertification and Electric Power Research Institute (EPRI) 89-10 Performance Prediction Program experience. These strengths give you an unequaled resource for improving plant availability, meeting regulatory requirements and reducing O&M costs.
We offer a comprehensive package of valve engineering, analysis and testing services ranging from design evaluation and prototype qualification for OEMs, to troubleshooting and design improvement for valves already in-service. As an independent laboratory, GVIRL produces unbiased assessments of valve performance problems. And we create solutions using the latest computerized analysis tools backed by realistic testing. The GVIRL “hot shop” can evaluate radioactive valves, and we can support plant cobalt reduction programs.
We can also perform comprehensive research, engineering and test capabilities for motor operated valves (MOVs). In fact, the EPRI and others selected GVIRL to conduct testing and research on MOVs to support the computer modeling programs developed to predict valve behavior for the industry’s 89-10 response. In applying sophisticated similarity analysis and grouping techniques and by leveraging existing industry data, GVIRL provides the most economical means of meeting plant O&M objectives and regulatory requirements like GL 89-10 and 95-07 requirements.
GVIRL offers the following engineering services:
- Design basis review
- Kinematic, dynamic and weak-link analyses
- Switch setting determination
- MOV diagnostic and upgrade services
- High-flow water and steam testing
- Failure mode analysis
Set Up to Save You Time and Money
The comprehensive valve/actuator database and in-depth field experience of GVIRL is designed to streamline the time and costs of meeting valve qualification needs. Our test capabilities include steam or water blowdown and flow testing up to 2,900 psi and 40,000 gpm capacities. This allows plant conditions to be accurately duplicated for virtually all in-service valves. GVIRL routinely performs ASME code recertification testing of safety relief valves (SRVs) as well as high-flow testing of MOVs, check valves and SRVs.
Our large-capacity facilities and extensive, hands-on experience guarantee a quick, unbiased response to your requirements, including:
- Steam set point/leakage tests
- On-site test services
- Refurbishment support
- Valve transportation and decon
- Steam/water blowdown testing
