As sub-suppliers can have a direct impact on the in-reactor performance of the fuel and core components, it is critical that the utility have a thorough understanding of the entire supply chain (i.e., key materials, processes, products, etc.). It is important to understand that many of the final in-reactor properties of the finished components are fixed at the sub-suppliers, long before they are delivered to the fuel and component vendors. As such, KLEIN CONSULTING has the capability to perform all of the previously described audit and surveillance activities at the material, piece parts, component and service suppliers that form the supply chain for the fuel and component vendors.
