Cavitation noise in nuclear reactors
Nuclear Engineering and Design, 1968Abstract An experimental investigation was made of the acoustical noise emitted by flow-induced cavitation in reactor fuel element coolant channels. Spectra of the acoustical noise emitted are shown and are correlated with optical measurements taken by means of short-exposure photographs.

On the theory of power reactor noise—III
Annals of Nuclear Science and Engineering, 1974Abstract An operating reactor has intrinsically fluctuating components in its state variables such as the thermal power, the outlet coolant temperature, the occupied region of control rods, etc. The fluctuations are generically called the reactor noise, the analysis of which, from both the theoretical and the experimental approach, is one of the ...

Time-domain noise analysis techniques such as the Rossi-[alpha], the variance-to-mean, and the interval-distribution methods can be used to measure fundamental reactor parameters in a wise variety of reactor systems, provided the power level of the system is not too high.

Application of reactor noise analysis in the candu reactors of Ontario hydro
Progress in Nuclear Energy, 1995Abstract Reactor noise analysis techniques are being applied in Ontario Hydro's CANDU nuclear generating stations to monitor the dynamic characteristics of critical plant components and processes. A comprehensive analysis of stationary signal fluctuations (noise) of the standard instrumentation of Pickering-B, Bruce-B and Darlington units has been ...

Abstract : Noise analysis experiments were conducted on the TRIGA-F reactor at the Armed Forces Radiobiology Research Institute at Bethesda, Maryland. A pseudo-random reactivity perturbation was inserted into a cold critical core. Power level fluctuations were monitored and an estimated transfer function was constructed.

Annals of Nuclear Energy, 1975
A review is given of reactor gamma noise studies, with the main emphasis laid on experience gained from subcritical reactors at Otaniemi, Finland, along with a survey of the development of stochastic models, numerical studies and gamma noise measurements. Within the framework of a space-independent two-energy-group model that has been developed, all

Analysis of pool-type reactor noise
Progress in Nuclear Energy, 1977Abstract A theoretical and experimental analysis is presented of pool-type reactor noise caused by thermal hydraulic and mechanical phenomena. The thermal hydraulic model is based on fluctuations of coolant inlet temperature and coolant velocity as noise sources.

Reactor noise standards in the U.S.A.
Progress in Nuclear Energy, 1988Abstract The American Society of Mechanical Engineers (ASME) has fostered the development of codes and standards to be used by all facets of the general industry. The ASME Committee on Operation and Maintenance of Nuclear Power Plant (O&M Committee) currently has responsibility of 20 ASME nuclear power standards addressing areas such as “Requirements

Power reactor noise measurements in Hungary
Annals of Nuclear Energy, 1975The history of the reactor noise research in Hungary can be divided into three parts. In the first period some very fundamental research work has been done in the field of zero-power reactor noise [I-3]. This theoretical work initiated experimental zero-power reactor noise research: Rossi-~, Feynman and, correlation function measurements, determination
