“…For example, a fire in Hinsdale, IL in 1985 caused widespread smoke damage to electronics in a telecommunications central office. 5 The major focus of research based on this fire was (1) estimating the amount of soot or chemical deposits that can cause long term damage to electronics, (2) determining which types of cable insulation and jackets will produce the least damaging chemicals, and (3) developing methods to control the movement of smoke. Most of the concern about the electronics was focused on determining if the equipment could continue to operate after a fire or, if not, be could be salvaged (generally involves cleaning off soot deposits).…”

“…The fourth set of tests was performed on functional circuit boards developed by the Low-residue Soldering Task Force (LRSTF). 2 1 The boards were developed to determine how different low-residue soldering practices would affect the quality and cleanliness of circuit boards. This board contained different types of circuits constructed of COTS and milspec components.…”

“…Some of the most important questions addressed in this paper are: (1) the selection of the plant areas for site survey measurements and susceptible equipment to be tested for immunity; (2) selection of the representative electromagnetic disturbances that shall be simulated during those tests; and (3) practical performance (i.e., coordination of immunity tests with operation of other plant systems and minimization of the undesired interference). Site survey guidance can be partially found in several papers [6], which are mostly outdated, as well as IEEE Std. 473-1985, which has been withdrawn.…”

Room Classification Based on EMC Conditions in Nuclear Power Plants

Electromagnetic compatibility (EMC) in nuclear power plants today mostly relies on the qualification tests of the new equipment and adhering to some good installation practices. Diversity of the electromagnetic environment and different susceptibility of the plant equipment calls for a systematic classification of the EMC zones in a nuclear power plant. The paper proposes a methodology that uses a combination of the qualification tests, in situ and bench immunity tests, site survey measurements, operational experience, and numerical calculations to divide a nuclear power plant into a reasonable number of EMC zones. This would primarily help to have a better overview of the current EMC level in the plant and to unify emission and susceptibility requirements for the new equipment. In this paper, special attention is given to the preparation and performance of the in situ tests, which present the most challenging step of the methodology. In addition, the paper proposes some of the possible applications of the numerical calculations and addresses their challenges and limitations. The novel classification methodology, inspired by the equipment qualification program, is illustrated with examples from Krško Nuclear Power Plant, which recently performed a comprehensive EMC assessment.
