Collection and analysis of component failure data from jet systems: neutral beam injectors and power supply

T. Pinna, G. Cambi, F. Gravanti2007年被引用 7Nuclear FusionIF 3出版社

The objective of this ongoing activity is to develop a fusion specific component failure database with data coming from operating experiences gained in various fusion laboratories. The activity began in 2001 with the study of the Joint European Torus (JET) Vacuum and Active Gas Handling Systems. Two years later the neutral beam injectors (NBI) and the power supply (PS) systems were considered and since last year the ion cyclotron resonant heating system is under evaluation.The number of failures/malfunctions that have occurred during the years of operations, failure modes and, where possible, causes and consequences of the failures were identified, as well as the sets of components under analysis. Components were classified and counted in order to determine component counts by type of component, related total operating hours and related demands to operate (for components operating in an intermittent manner). Main reliability parameters (such as the failure rate and corresponding standard errors and confidence intervals) for the component types were also estimated. In this paper the NBI and PS results are presented.

本活動の目的は、様々な核融合実験施設で得られた運転経験に基づくデータを用いて、核融合装置固有の構成要素の故障データベースを構築することである。この活動は2001年に開始され、当初はJET(共同欧州トーラス)の真空及び活性ガス処理システムの調査から着手した。2年後には中性粒子入射装置(NBI)と電源システム(PS)が対象に加えられ、昨年からはイオンサイクロトロン共鳴加熱システムの評価が進められている。運転期間中に発生した故障・不具合の件数、故障モード、可能な範囲での故障原因と影響が特定され、分析対象となる構成要素の集合も明確化された。構成要素は種類ごとに分類・計数され、各構成要素タイプの数量、関連する総運転時間、および(間欠運転する構成要素については)関連する作動要求回数が決定された。さらに、構成要素タイプごとの主要な信頼性パラメータ(故障率、対応する標準誤差、信頼区間など)も推定された。本論文では、NBIとPSに関する結果を提示する。
