Curtiss-Wright Nuclear Canada offers seismic testing service from conception to completion: 

• Procedure Preparation
• Custom test specimen fixturing
• Custom test specimen monitoring
• Reporting

As one of the testing facilities for the EPRI SQURTS program, we offer industry-recognized seismic qualification for EPRI members.

The CWNC facility offers a comprehensive set of equipment qualification capabilities no matter what the requirements:

• Harsh and Mild Environments (High Temperature and High Humidity Testing)
• LOCA (Loss of Coolant Accident) Testing
• Thermal and Mechanical Aging
• Radiation Services
• Gamma Radiation Qualification
• Electromagnetic Interference/Compatibility Testing (EMI/EMC)
• Software Qualification to CSA N290-14
• Testing Facility for the EPRI SQURTS Program

All of the above can be completed individually depending on component and project requirements. CWNC completes this testing from conception and development to completion and qualification.

CWNC has the historical data, knowledge, and experience to assist with the qualification of commercial grade items for use in nuclear safety-related applications.

Our methodology begins with a dedication procedure that includes:

• Full Services Commercial Grade Dedication (CGD) Services
