Corrosion Testing Framework for STEP
The purpose of this procurement is to establish a framework agreement with a number of pre-qualified, specialist corrosion testing providers to deliver corrosion testing services for the UKFE STEP programme over the next two years. The framework will enable efficient and compliant call-off contracts for testing of high-temperature coolants, carrier gases, and breeder materials against STEP coolant-facing alloys and candidate tritium breeding materials as requirements arise. The framework is intended to streamline p...
