AbstractThe Materials Characterization Center (MCC) at Pacific Northwest Lab- oratory is performing three kinds of corrosion tests for the Basalt Waste Isolation Project (BWIP) to establish the interlaboratory reproducibility and uncertainty of corrosion rates of container materials for high-level nuclear waste. The three types of corrosion tests were selected to address two distinct conditions that are expected in a repository constructed in basalt. An air/steam test is designed to address corrosion during the operational period and static pressure vessel and flowby tests are designed to address corrosion under conditions that bound the condi ring the post-closure period of the repository.The results of tests at reference testing conditions, which were defined to facilitate interlaboratory comparison of data, are presented. Data are reported for the BWIP/MCC-105.5 Air/Steam Test, BWIP/MCC-105.1 Static Pressure Vessel, and BWIP/MC-105.4 Flowby Test. In those cases where data are available from a second laboratory, a statistical analysis of interlaboratory results is reported and expected confidence intervals for mean corrosion rates are given. Other statistical treatment of data include analyses of the effects of vessel-to-vessel variations, test capsule variations for the flowby test, and oven-to-oven variations for air/steam tests.

The purpose of this study is to analyze the process of performance evaluation of vendors especially in the vendor that provides a raw material for pressure vessel plate made of carbon steel. As for the evaluation process undertaken by PT. XYZ through performance indicators (KPI) where an evaluation that applied a focus on quality and delivery. In this study, researchers used the designation criteria vendor performance indicator (VPI) where the criteria used consist of quality, cost, delivery, flexibility and responsiveness (QCDFR). The methods used in the analysis process that is Analytical Hierarchy Process (AHP). Data collecting directionally by questionnaire method among 3 respondents on the procurement department that know the performance of the vendors over the years. The result showed that PT. RE has the best performance among the four vendors, as known PT.SS, PT. ST, PT. CH and PT. UN within value 0.540; The vendor with lowest performance owned by PT.CH within value 0.034.Keyword : Analytical Hierarchy Process (AHP), vendor performance indicator (vpi), plate pressure vessel, vendor performance evaluation Penelitian ini bertujuan untuk menganalisis proses evaluasi kinerja vendor khususnya pada vendor yang mensupplai bahan baku plate pressure vessel berbahan carbon steel. Adapun proses evaluasi yang dilakukan oleh PT. XYZ melalui key performance indicator (KPI) dimana evaluasi yang diterapkan hanya berfokus pada quality dan delivery. Dalam studi ini, peneliti menggunakan penetapan kriteria Vendor Performance Indicator (VPI) dimana kriteria yang digunakan yaitu quality, cost, delivery, flexibility dan responsiveness (QCDFR). Metode yang digunakan dalam proses analisis yaitu Analytical Hierarchy Process (AHP). Pengambilan data menggunakan kuisioner terhadap 3 informan pada departemen procurement yang dianggap mengetahui kinerja vendor selama ini. Adapun hasil penelitian menunjukkan bahwa PT. RE memiliki kinerja yang terbaik diantara keempat vendor yaitu PT. SS, PT. ST, PT. CH serta PT. UN dengan nilai bobot sebesar 0.540 sedangkan vendor dengan kinerja terendah dimiliki oleh PT. CH dengan nilai bobot sebesar 0.034.Kata kunci : Analytical Hierarchy Process (AHP), vendor performance indicator (VPI), plate pressure vessel, evaluasi kinerja vendor.
