Description
EEnsuring the safety of personnel, the environment, and equipment during operation of the Wendelstein 7-X (W7-X) superconducting fusion experiment is a fundamental legal requirement. A central objective of the W7-X development is therefore to reduce the inherent hazard potential through technical, organizational measures and personal safety measures to a level at which the remaining residual risk is acceptable.
The safety control systems of W7-X are designed in accordance with IEC 61511 (functional safety for the process industry).
Since the start of W7-X operation in December 2015, the cSS has been continuously adapted to meet increasing safety requirements, mainly driven by the integration of new technical systems and diagnostics. During previous conversion phases, however, the cSS was shut down.
To reduce or largely eliminate extensive organizational measures, the cSS is being modified for operational phase OP2.4 to enable safety-relevant operation also during conversion and assembly phases by implementing appropriate safety functions.
This paper presents the architecture and core functions of the cSS, followed by a detailed description of the modifications introduced to support safety operation during assembly phases. Newly implemented safety functions, special operating modes, and modifications to the interface cabinets of the cSS for OP2.4 are described. Finally, first results from the commissioning of the enhanced cSS are discussed.
nally, first results from the commissioning of the enhanced cSS are discussed.
