Prototype Instrument for Controlling Reactor Startups

IEEE Transactions on Nuclear Science, 1967
A time-to-power instrument has been developed for use as a primary startup control for nuclear reactors. Time-to-power (TTP) is the projected length of time that will elapse before reactor goal power is reached, as based on the instantaneous neutron flux level and the reactor periods. Thus, the TTP signal is formed by combining the logarithm and period

Status of research reactor instrumentation in the USA

Physica B: Condensed Matter, 1991
Abstract Significant upgrades are planned or are occurring in most of the existing major beam-research reactors in the United States. These range from the installation of new instruments to major additions such as cold neutron guide halls. In this paper the current status and planned upgrades are reviewed for four of the major US reactor facilities ...

The temperature scanning reactor: A kinetics instrument

Chemical Engineering Communications, 2003
The application of temperature scanning methods of kinetic experimentation is explained, documented, and illustrated with two examples. The experimental procedures involved as well as an outline of the required methods of data handling are presented and the advantages of this technique brought out.

The impact of transistors on the design of reactor instruments

Journal of the British Institution of Radio Engineers, 1962
The requirements of reactor instruments demand an unusual emphasis on the philosophy of fail to safety, guaranteed power supplies in all circumstances and reliability over long periods of operation. The special advantages of transistors in the development of these instruments are simplicity of circuit and economy of power required.

Instrumented in-reactor test capabilities in FFTF

Journal of Nuclear Materials, 1981
Abstract Fusion materials research and development requires high neutron fluxes coupled with a large irradiation volume. Both of these needs can be provided by the Fast Flux Test Facility. The Materials Open Test Assembly, the vehicle used for materials irradiations in the FFTF, is described.

The Instrumentation and Control Circuits of Nuclear Reactors

Proceedings of the IRE, 1962
The chain reaction which takes place in a nuclear reactor is a regenerative process and can therefore be unstable, so the fission rate must be closely controlled in order that the nuclear reaction may proceed at a rate which is both useful and safe. Electronic circuits play a vital part in this, and their reliability must be exceedingly high, as many ...

Health physics instrumentation for a power reactor

Electrical Engineering, 1957
No standards exist today for instrumentation adequate to insure health and safety in and around a power reactor. However, it is possible to outline the measurements required, the required ranges and accuracies, and classes of instruments and their application. Based on these outlines, instrumentation for a representative power reactor is suggested.

Instrumentation and control of the Brookhaven nuclear reactor

Transactions of the Institute of Radio Engineers Professional Group on Nuclear Science, 1954
Safe startup and operation of the nuclear reactor require neutron-sensing instruments to cover a range of about 109. This coverage is obtained by a counting rate meter, a period meter, and a high level power indicator. At normal operating levels, the reactor is regulated by the high level power controller and protected by the high level trips ...
