DIGITAL SIGNAL PROCESSING CHANNELS
Digital neutron  ux monitoring channels system TK 250 are characterized by ef cient functions, useful procedures for periodical testing, a comfortable operators menu structure and a rugged operational behaviour. Hardware and software are arranged in modules. The internal multiprocessor structure offers the  exibility of reducing the region of highest safety relevance to a small, separated part within the chan­nel.

The signal processing system TK 250 includes neutron  ux monitoring channels for BWR and PWR, and for research
reactors, which are designed and quali ed for applications within the reactor protection system:
DAK 250 Digital Start-Up Channel
For the pulse range (DAK 250-i) with pulse detec-
tors and for the intermediate range (DAK 250-g) with ionization chambers with linear or logarithmic output signal and reactor period signal, optional module for reactivity calculation
DGK 250 Digital Power Range Channel
For processing and numeric calibration of one or two
signal paths with boron coated ionization chambers
DSK 250 Local Power Range Channel
With four signal paths for in-core  ssion chambers in
the BWR
DWK 250 Digital Wide Range Channel
For combination of pulse and Campbell (RMS) signal
processing together with in-core (BWR) or ex-core (PWR)  ssion chambers with pulse, intermediate, and wide range  ux signal and reactor period signal
