The Beamline Personnel Safety System (BPSS) at Angstroemquelle Karlsruhe (ANKA) started operation in 2003. The paper describes the safety related design and evaluation of serial, parallel and nested radiation safety areas, which allows the flexible plug-in of experimental setups at ANKA-beamlines. It evaluates the resulting requirements for safety system hard- and software and the necessary validation procedure defined by current national and international standards, based on probabilistic reliability parameters supplied by component libraries of manufacturers and an approach known as 'Designated Architectures', defining safety functions in terms of sensor-logic-actor chains. An ANKA-beamline example is presented with special regards to features like (self-) Diagnostic Coverage (DC) of the control system, which is not part of classical Markov process modelling of systems safety.
