Title: INSTALLATION AND INTERFERENCE PROBLEMS IN REACTOR INSTRUMENTATION SYSTEMS

Abstract

Reactor control instrumentation systems may be subject to a variety of extraneous signals. Five types are discussed: signals involving high-frequency components which may gain access to critical circuits through wiring that lacks suitable RF filtering; current signnls due to mechanical shocking or flexing of cables; extraneous ion chamber signals, including displacement currents due to fluctuations in the polarizing voltage, as well as currents caused by mechanically induced changes in ion chamber capacity; signals whose origin is magnetic induction into cable loops; and signals involving magnetic induction and ohmic induction into auxiliary loops created by multiple ground connections. The emphasis is placed on magnetic induction and means of eliminating it. (auth)
