Abstract

1533789 Fault finding in coolant systems EUROPEAN ATOMIC ENERGY COMMUNITY 7 May 1976 [7 May 1975] 18966/76 Heading G1N Temperature fluctuations in the coolant for a nuclear reactor are measured by a sensor 4 Fig. 1 located downstream of a bundle of rods 1, consisting of two thermocouples in series opposition, one with a short time constant and the other with a long time constant. The fluctuations T are analyzed to determine where p(T) is the probability density function, and γ in S is the root mean square value of T. The value and the sign of the factor S is said to be indicative of the size and position of a blockage 5 in the coolant channel 2.
