Abstract |
This report documents the initial procurement activities from the Superior Tube Company (STC) associated with production quantities of Zircaloy-4 components (Contract 330088-A-T9) and the demonstration of their capability to produce full-length getter (FLG) components (Contract 406957-A-T5). Advanced planning for this contract began in spring 1999. STC was awarded a firm, fixed-price contract with the potential for added incentive payments based on their ability to control their manufacturing processes. Incentives were included in this contract based on the potential benefit to reduce Pacific Northwest National Laboratorys (PNNLs) quality costs and schedule risk. The contract was negotiated to a firm fixed price plus incentives with a not-to-exceed price. The manufacturing activities for the contract included two phases. The first phase consisted of demonstrating production capability for the production of getter-tube stock and inner-liner tubes. The second phase originally consisted of procuring Zr-4 feedstock and producing Zr-4 components, but 13 modifications were made to the contract. There were delays, but STC was able to produce the required amount of components as specified by their contract. There were concerns regarding product quality, including the inside diameter, the outside diameter, and straightness characteristics. Non-contact methods of inspection were implemented to minimize flexing of the tubes during inspection, and the design specification was revised to allow averaging of measurements. Along with the inspection and specification changes, STC continued to pursue process improvements that would yield a better product. Even though the product quality improved significantly, some lots still failed the initial inspection, resulting in a 100% inspection for those lots. |
