Commissioning is the process whereby constructed WTP components and systems are verified by testing to meet requirements and subsequently placed into service.

Each WTP facility undergoes a sequence of tests of progressively increasing complexity that demonstrate the facilities meet contractual, regulatory, and functional design requirements.

This testing sequence starts with simple component tests progressing to larger, more complex demonstrations at the system and facility level, culminating with integrated facility demonstrations with chemical simulant and ultimately, radioactive wastes.

This sequence includes readiness and management assessment activities at key points to ensure the WTP Project is ready to introduce new or more significant hazards.

Once a system has been successfully verified during startup testing it will undergo the commissioning phase. During commissioning, workers calibrate, prepare, and maintain the facility, operating staff, and programs and procedures for radioactive waste operations.

All Vit Plant facilities will undergo the startup and commissioning process before being deemed ready to be turned over for operations. This organized, phased approach is an industry best practice to safely build, test, and activate other large, complex, government-regulated projects.
