Collection and analysis of data related to fusion machines (JET and TLK) operating experience on component failure

Tritium Room Air Monitor Operating Experience Review

“…1,[3][4][5][6] These data are given in Table I. The combined failure to function rate value from the three diverse data sets is estimated to be 3.5E 06/monitor-hr with an upper bound of 4.7E 06/monitor-hr.…”

Comparison of Tritium Component Failure Rate Data

“…Despite the inability to perform a significant update on the TSTA component failure rate data values, comparing the collected data sets from TSTA [13][14][15][16] and other facilities remains a valuable exercise to validate the data. Pinna 17 has reported on an extensive data analysis performed on JET and TLK. Yamada et al 18,19 have reported two data sets on TPL.…”

Data collection on component malfunctions and failures of JET ICRH system

“…Similar data collection and analyses performed for the ICRH were also performed in the past, by ENEA, on other JET systems, namely the vacuum, the active gas handling, the neutral beam injector (NBI) and the power supply (PS) systems, Pinna et al [3,4]. Data from the Tritium Laboratory of Karlsruhe (TLK) were also considered (see [3]).…”
