EMI/RFI Testng
As an industry leader in providing digital I&C to utilities, Westinghouse has developed the knowledge and experience base to perform successful EMI evaluation, testing and design.
Westinghouse can verify that the digital equipment in U.S. plants complies with applicable EMI NRC Regulatory Guides, American National Standards Institute/ Institute of Electrical and Electronics Engineers, Electric Power Research Institute (ANSI/IEEE, EPRI) and/or Military (MIL) Standard requirements.
Globally, Westinghouse can verify that digital equipment complies with the European Union (EU) directives and International Electrotechnical Commission (IEC) requirements for Conformité Européene (CE) certification.
Site Support
Westinghouse’s experienced personnel can perform equipment walk-downs to confirm that safety-related equipment is installed in the facility in the same manner in which it was qualified, and to determine the seismic resistance of equipment. Westinghouse staff can conduct onsite modal and vibration testing to determine the natural frequencies and equipment responses needed for seismic qualification.
Regulations and Standards
Testing and analysis are performed in accordance with regulations and standards, including the following:
- NRC Regulatory Guides and requirements
- IEEE Std. 34, IEEE Std. 323 and supporting standards
- IEC International Standards
- Uniform and International Building Codes
- American Society of Mechanical Engineers
- ASME, American
- Institute of Steel Construction and other industry codes
- EMI directives and guidelines
